Findings Of Fact On October 15, 1982, Hal Thomas Reid Associates applied for a septic tank permit to serve a 16-room motel. On February 2, 1983, this application was amended to a 5,800 gallon septic tank to serve a 32-unit condominium and office. The lot on which this drain field is to be located is 70 feet by 100 feet. When the application was filed, the lot was inspected by the Citrus County Health Department. The elevation of the land averaged 2.5 to 2.9 feet above mean sea level. The 10-year flood plane in this area is 4.9 feet. Occasional high tides inundate this area; however, the water drains off rapidly and no one testified that water ever remained standing as long as seven consecutive days. Usually the water drains off in less than 24 hours. On March 1, 1983, an extremely high tide flooded this area and roads in the vicinity to a depth of approximately one foot. This water remained on the site less than 24 hours. The site is not located adjacent to state waters, is not an area designated as wetlands, and is without the dredge and fill permitting jurisdiction of the United States Army Corps of Engineers and the Florida Department of Environmental Regulation (Exhibits 20 and 21). By adding five feet of fill to the site, the bottom of the gravel below the drain pipes will be above the 10-year flood plane. The drain field capacity is adequate to handle the flow from 33 bathrooms of residential units. In approving this permit, the Citrus County Health Department used the 150 gallons per day discharge for residential units rather than the 100 gallons per day discharge from a motel unit. The water table at this location is two feet above mean sea level. This is determined by the elevation reached at high tides for 14 consecutive days. As a condition to Citrus County withdrawing as an intervenor in these proceedings, Applicant agrees: To revegetate and restore any alleged wetlands affected by the permit to a like or similar condition; To install three shallow draft monitor wells around the drain field towards the wetlands area adjacent to the site and towards Woods 'n Waters subdivision, establish an existing level of bacteria count prior to the activation of the septic tank, and to monitor said wells through the Citrus County Health Department on a quarterly basis; and In the event any monitor wells shall test at an unsatisfactory level, Applicant will forthwith correct this condition to the satis- faction of the Citrus County Health Department. This application meets all of the code requirements of Chapter 10D-6, Florida Administrative Code.
The Issue The issues are: (1.) Whether Respondents' request for variance from requirements of Rule Chapter 10D-6, Florida Administrative Code, should be granted. (2.) Whether Respondents are guilty of violation of certain provisions of Chapter 381 and Chapter 403, Florida Statutes, and Rule Chapter 10D-6, Rule Chapter 17-550, and Rule Chapter 17-555, Florida Administrative Code, regulating the operation of onsite sewage disposal systems.
Findings Of Fact Respondent V.M.P. Corporation (VMP) operates a lounge known as Stud's Pub in Jacksonville, Florida. Licensed for 75 seats, the lounge actually contains 50-55 seats and employs five people full time. Additionally, 10-15 independent entrepreneurs known as dancers may be present at times. The dancers are not employees of Respondents. Less than 25 people, other than patrons, are present at the facility at any time. Respondent Vincent M. Paul (Paul) owns the facility and the corporation. The lounge is on lots that were platted prior to 1972. Petitioner is the statutory entity with authority for granting variances for onsite sewage disposal systems regulated by Petitioner pursuant to provisions of Section 381.0065(8)(a), Florida Statutes (1991). The lounge is serviced by a septic tank with a drainfield which is covered by an asphalt parking lot. The portion of the parking lot over the drainfield is bounded to the west by a dirt city street, to the north by other pervious surfaces, to the east by the lounge and to the south by the remainder of the asphalt parking lot. A sign on the premises which advertises the business is protected from automobile traffic by concrete barriers. The septic tank system and drainfield were installed prior to 1972 by a previous owner. Respondent Paul retrofitted the septic tank system after 1972. Respondent Paul was responsible for paving over the drainfield after he purchased the property. Petitioner's representatives inspected the lounge, determined the drainfield to be covered by the asphalt parking lot and requested Respondents to remove the asphalt covering. Respondents requested a variance pursuant to Rule 10D Administrative Code, for the asphalt covered drainfield and other deficiencies of the onsite sewage disposal system. Petitioner's review board recommended denial of the request on the basis that the variance would not constitute a "minor deviation" from rule requirements. Although the term is not defined by Petitioner's rule, Petitioner's usage of this term was the result of the consideration by Petitioner's review board of the application for variance within the context of Section 385.0065(8)(a), Florida Statutes, which authorizes Petitioner to grant variances only where the hardship is not intentionally caused by the applicant, where no reasonable alternatives exist and where no evidence of adverse effect upon public health or ground and surface waters is demonstrated. Respondent has no record of failure of the septic tank or drainfield. Water samples from the onsite potable water well filed with Petitioner tested below detectable limits for nitrates and coliforms, the only parameters Petitioner is required to analyze. Respondents' records of water flow or usage from the well into the lounge show daily flow rates of between 320 and 580 gallons, with an average rate of between 450 and 480 gallons. Respondent Paul is responsible for the installation of an unpermitted chlorinator on the water supply system which provided actual flow information. The only onsite water well has no grout sealant. It is the only well of which the parties are aware that lies within 100 feet of the septic system. The potable water well is located approximately 42 feet from the edge of the covered drainfield. The well head does not extend above line surface and there is no concrete pad around the wellhead. The exact depth of the well is unknown, although the well is located upgradient of the drainfield and a nearby junkyard. Denial of the variance would require that Respondents uncover the drainfield since there is no practically available offsite sewage system currently available. Soil in the area of the drainfield is classified as well- draining sand. Due to the impervious surface covering the drainfield, Petitioner's representative was unable, during his inspection, to discern any symptoms of drainfield failure in the form of "blow field should be totally unobstructed to allow aerobic processes to take place in the drainfield which will permit the breakdown of contaminants. A portion of Respondents' 1200 gallon septic tank is located partially under and immediately adjacent to Respondents' facility. A dousing tank which retains liquid waste and operates as part of the septic system is also totally covered by the asphalt pavement. Although there has been no detectable failure of the system, every eight or nine months Respondents have the septic tank and dousing tank pumped out. The tanks never get full.
Recommendation Based on the foregoing, it is hereby Recommended that a final order be entered by Petitioner denying the variance requested by Respondent with exception of such minimal distance as may be required to relocate the water well as far as possible from the drainfield on the Respondent property, and, Further Recommended that such final order also assess Respondent Paul an administrative penalty of $500 for each of the four violations contained in the Administrative Complaint which were proven in this proceeding for a total of $2000, and a continuing assessment of $500 per day for each violation for a total of up to $2000 per day after first allowing Respondents a 60 day period within which to correct all four violations. DONE AND ENTERED this 3rd day of May, 1993, in Tallahassee, Leon County, Florida. DON W. DAVIS Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 3rd day of May, 1993.
The Issue The issues in this case concern the entitlement of Petitioners to the grant of a variance for the purpose of installation of an onsite sewage disposal system on property located in Dixie County, Florida. See Section 381.272, Florida Statutes and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact On April 27, 1989, the property which is at issue was deeded over to Diane H. and Charles A. Miller. The property is located in Dixie County, Florida, and contains 0.377 acres. On Nay 23, 1989, Petitioners were granted an easement for purposes of ingress and egress to and from the property. On May 4, 1989, under the signature of Diane H. Miller, a Petitioner in this case, an application was made for onsite sewage disposal at the aforementioned property. A copy of that application form may be found as Petitioners' exhibit No. 3 admitted into evidence. It states that this application is for a new system at lot No. 2, southwest corner, New Pine Landing Subdivision. Reference is also made to the directions to the property and suggestion that the property is located behind Nevin Kean Public Park [sic]. The warranty deed, a copy of which may be found as Petitioners' exhibit No. 1 admitted into evidence, describes the fact that the property is adjacent to Nevin Keen Public Park. The application form points out that this is a new system which is by type of residence "MH." It would contain two bedrooms and a heated or cooled area which is 12 feet by 60 feet. Also attached in Petitioners' exhibit No. 1 is a paper which purports to establish the benchmark elevation of the property as part of what that paper describes as the unrecorded subdivision at New Pine Landing. It speaks in terms of an elevation of 11.36 feet as allegedly surveyed by Herbert H. Raker. That information is hearsay and may not be used for purposes of fact finding in establishing the true elevation in an instance where Herbert H. Raker has not provided this explanation. See Section 120.58, Florida Statutes. As a consequence, there being no other explanation of the elevation, it is unknown. To the extent that it is accepted that there exists a New Pine Landing Subdivision, of which the Miller property is a part, evidence was not presented at the hearing which would establish the date upon which it was platted. Copies of the warranty deed and easement which were admitted into evidence do not indicate that the property is in New Pine Landing Subdivision, nor do they describe the date upon which the subdivision was platted, if ever. From the proof submitted, especially the warranty deed and easement, it does not appear that the parcel in question is part of a recorded subdivision. This coincides with representations by Ms. Virginia Sessions, whose daughter is Diane Miller. Ms. Sessions speaks in terms of this being an unrecorded subdivision and Petitioners' exhibit No. 4 admitted into evidence directed to Jermone Blake of the Dixie Public Health Unit on stationery of Suwannee River Water Management District refers to this location as New Pine Landing. Under the circumstances it is accepted that this parcel lies within an unrecorded subdivision known as New Pine Landing. There was a period of time during which the applicants did not receive a response from Respondent concerning the request for a permit to install the onsite sewage disposal system. Ms. Sessions testified that her daughter made a phone call to the Respondent to determine the status of the application and that the daughter reported that someone affiliated with Respondent said that Respondent would be getting back in touch with the applicants. This report by Mrs. Sessions of her daughter's remarks concerning a purported conversation between the daughter and the Respondent's employee is hearsay and may not be used to decide whether in fact there was a communication between the daughter and the Respondent. See Section 120.58, Florida Statutes. In any event, Mr. Blake communicated with Mrs. Sessions and informed Mrs. Sessions that the Petitioners would not be given a permit for installation of an onsite sewage disposal system and would need to file a request for variance from the requirements to obtain permission to install the onsite sewage disposal system. In furtherance of that instruction, the appropriate fee was paid and a form executed by Mrs. Sessions requesting a variance. A copy of that variance request may be found as Petitioners' exhibit No. 8 admitted into evidence. The date of that application was July 13, 1989. The form makes reference to the authority of the agency to examine the request for variance as being set forth in Chapter 381, Florida Statutes, and Chapter 10D-6, Florida Administrative Code. The form points out to the applicants that the variance may not be granted unless: The Department is satisfied the stated hardship was not caused intentionally by the applicant. A reasonable alternative sewage treatment method is not available The sewage discharge will not adversely affect public health and/or significantly degrade ground or surface water quality. The application for variance makes reference to the New Pine Landing Subdivision. It states that the parcel in question is lot No. 2, and makes reference to a book and page number and a plat number and purported page number associated with the plat number allegedly pertaining to the subdivision. Competent evidence was not presented to establish that these references found on the application were correct portrayals of the recordation of the subdivision and plat number. See Section 120.58, Florida Statutes. Again, this leaves the record incomplete as to any recordation of the existence of the subdivision and a plat number associated with that subdivision. The application describes the reason for requesting a variance as related to the fact that the lot is in a flood area where more than 36 inches of fill dirt may not be added. Proof was not submitted at hearing concerning the exact nature of the property in question; however, Mrs. Sessions as the person who had applied for the variance and has a layperson's knowledge of the property in question, is entitled to depict the general nature of the property and her explanation that it is flood prone is accepted. How much fill dirt may be added to the property was not established by competent evidence. Under the instructions for the owner associated with the application for the variance, the applicants are told that they should provide any supportive material and documents to the County Health Unit in Dixie County, Florida. This entails submission of a site plan, site location and reference map. These details were not submitted with the application as far as the record reveals. More importantly they were not provided at hearing. The instructions call upon the applicants to satisfy the terms of Section 381.272(2) and (3), Florida Statutes, and to state the reasons for requesting the variance under the requirements of Chapter 10D-6, Florida Administrative Code. The applicants were told to explain why variance from the requirements would relieve or prevent excessive hardship and to provide technical documentation to support the supposition that a variance would not likely result in pollution or impairment to public health. Written on the form submitted is the suggestion that this project is a variance from the requirements of Rule 10D-6.047(6), Florida Administrative Code, related to the 10 year flood event. The application points out the size of the parcel as being approximately .38 acres and the sewage flow anticipated is 250GPD. It points out that the drinking water supply is a private source. It points out that the type of residence is a single-family retreat that has two bedrooms. It describes the proximity to sanitary sewer as 13 miles and to public water supply as 7,500 feet. The distance to private wells is said to be 775 feet and to a stream 7,400 feet. The proposed system that the applicant has in mind is a septic tank and drain field that is mounded. The system is referred to as a subsurface septic tank and drain field with six inches of fill sand. Although the application describes that the water table during the wettest season of the year is below the ground surface by 36 inches and at the time testing was done that the water table was below the ground surface and "not found 72 inches," competent proof of these assertions was not presented in the course of the hearing. The description of the type of soil as being sand is accepted. Nothing more was revealed about the soil characteristics. The application points out that the 10 year MSL flood elevation is 14 feet and that the property elevation MSL is 11 feet. Competent evidence of those facts was not presented at hearing. Nor was there competent evidence of the adequacy of the surface water drainage at the property site. The application form points out that the Dixie County Health Unit recommended approval of the variance on July 13, 1989. That says that the property is in the Suwannee River floodway where maximum fill allowed is 36 inches and that mounds are subject to erosion and moving water. It is accepted that the property is in the area of the Suwannee River. The other facts that are suggested in these summary remarks were not established by competent evidence. The form reminds the county health unit that procedures associated with the variance requests must comply with Section 120.60, Florida Statutes. The county staff is instructed to list additional details in terms of the site evaluation and tell why standards cannot be met if that is the opinion held. It reminds them to reference the specific sections within Chapter 10D-6, Florida Administrative Code, and Section 381.272, Florida Statutes, that are involved with the variance request and state reasons why a recommendation of approval or disapproval is being made. The completed form is then submitted to the Environmental Health Program ten days prior to any scheduled Variance Review Board meeting date. Substantiating documents must be submitted in place of or in addition to the data just described to include the application for septic tank permit, denial letter and engineering report and USDA Soil Conservation Service reports. Based upon this record an engineer's report has never been submitted. More particularly, an engineer or acceptable substitute did not present evidence supporting the variance. Mrs. Sessions received an August 18, 1989 letter from Richard G. Hunter, PHD, Assistant Health Officer for Environmental Health. A copy of this may be found as Petitioners' exhibit number 5 admitted into evidence. It requests that additional information be provided to the Dixie County Public Health Unit associated with the date that the lot was subdivided from lot 2, if it was subdivided at one time. Mrs. Sessions testified that she responded to this request. The exact information that she provided was not presented at the hearing. Consequently, it is not clear whether the information that was presented satisfied that review group. Within the correspondence of August 18, 1989, is mention of the fact that the review group will consider the variance request at a September 7, 1989 meeting in Tampa, Florida, assuming that the information that had been requested was provided by August 28, 1989. On November 29, 1989, Kevin M. Sherman, PHD, M.P.H., Environmental Administrator, Environmental Health Programs wrote to Mrs. Sessions to advise her that the application for variance had been placed on a meeting agenda for December 7, 1989 in Sarasota, Florida. A copy of this may be found as Petitioners' exhibit No. 6 admitted into evidence. This is seen as an acceptance of the application for purposes of making a decision on the merits. Neither Petitioners nor someone representing their interests attended the December 7, 1989 meeting in Sarasota, Florida. On December 13, 1989, Dr. Hunter wrote to Mrs. Sessions to advise her that the request for variance had been rejected. A copy of this letter of rejection may be found as Petitioners' exhibit No. 7 admitted into evidence. It reminds the applicants that the purpose of the grant of a variance is for relieving or preventing excessive hardships where it can clearly be shown that the public health will not be impaired and where pollution of groundwater or surface water will not result. The basis of rejection was that the request was not considered to be a minor deviation from minimum requirements specified in Rule 10D-6.047(6), Florida Administrative Code. The letter of rejection advised Petitioners of their right to a hearing. That request for hearing was made on January 11, 1990, within the 30 days allowed for making such requests. Testimony presented by Alma Walker did not establish the nature of the New Pine Landing Subdivision and whether it had been recorded or not and the date that the property may have been platted. Mrs. Walker talked with a person within the Dixie County Health Unit whose name is Frost. This gentleman told Mrs. Walker that the case had been referred for a hearing and that the applicants should continue to pursue that matter. His secretary made some remark to Mrs. Walker concerning the impression that six inches of fill is less than allowed for septic tanks. This representation is not considered to be competent evidence as to the amount of acceptable fill. Mrs. Walker's comments concerning the applicants seeking a new benchmark from a surveyor and the suggestion that the surveyor gave this information to Mr. Frost is hearsay and does not establish the fact that a surveyor presented a new benchmark for the property to Mr. Frost. Nonetheless, following this circumstance Mrs. Walker spoke to Mr. Frost about the survey to establish benchmark and was told by Mr. Frost that the applicant still could not get a permit because of not meeting the requirements of the 10 year floodplain. Petitioners' exhibit No. 4 admitted into evidence attempts to describe the impression of the application for a variance as held by the Suwannee River Water Management District. It is hearsay and may not be used to find facts in that competent evidence about the opinion of the Suwannee River Water Management District as to the acceptability of the variance request was not presented at hearing.
Recommendation Based upon the consideration of the facts found and the conclusions of law, it is, RECOMMENDED: That a Final Order be entered which denies Petitioners request for a variance from the requirements to obtain a permit for onsite sewage disposal. DONE and ENTERED this 8th day of June, 1990, in Tallahassee, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 8th day of June, 1990. APPENDIX CASE NO. 90-1204 The following discussion is made of the fact finding suggested by the parties. Petitioners' Facts Paragraph 1 is subordinate to facts found. Paragraph 2 is subordinate to facts found with the exception of suggestion that a benchmark elevation was determined. No competent evidence was presented to establish the benchmark elevation. Paragraph 3 is subordinate to facts found in the sense that it is acknowledged that an application for onsite sewage disposal system permit was made. Proof was not established that all necessary information required by law was presented with the application. Paragraph 4 with its discussion of the significance of information provided by the Suwannee River Water Management District is not accepted to the extent that it attempts to describe the entitlement to a permit based upon remarks made by the Suwannee River Water Management District. The issue of whether adequate reasons were given for denying the permit application was not noticed for consideration at the final hearing and to the extent that that issue has any relevance in considering the variance request Petitioner's have failed to demonstrate any prejudice to their cause in pursuing the variance request. Paragraphs 5 and 6 are subordinate to facts found. The indication in paragraph 7 that Petitioners were having to reapply for a variance does not coincide with the understanding of this process in which the facts tend to establish that the initial variance request was processed to conclusion. In Paragraph 8 the idea of reapplication is rejected as is the contention that there was a failure in the explanation as to the reasons why the variance was denied. The explanation was adequate to notice the Petitioners of the reasons which the agency had in mind in denying the variance application. Respondent's Facts Paragraphs 1-7 are subordinate to facts found. Paragraph 8 constitutes a conclusion of law.

Findings Of Fact Petitioner owns property adjacent to Sims Creek located in Palm Beach County, Florida. Petitioner is undertaking a development on the property. The development was initiated by the Great American Anvil Corporation, the previous owner of the property. The development as originally conceived included construction of a dock in Sims Creek. The Great American Anvil Corporation applied for a permit to the State Board of Trustees of the Internal Improvement Trust Fund. On February 5, 1975, a permit was issued to allow Great American Anvil Corporation "to construct eight (8) finger piers each twenty feet long by two feet wide, and three triangular piers twenty feet long by five feet wide at the base and two feet wide at the top" in Sims Creek. The permit was issued for construction of the docking facility and by its terms expired on a specified date. The permit was never assigned or transferred to Petitioner. The permit has expired, and is no longer effective. A bulkhead has already been constructed along Petitioner's property. Petitioner is seeking a permit which would authorize it to construct a perimeter dock which would run along the approximately three hundred foot border of Petitioner's property and Sims Creek, and extend four feet over Sims Creek. Petitioner is also seeking to construct ten piers out from the perimeter dock, each of which would be twenty-five feet long and two feet wide. Mooring spaces would be provided for sixteen or more boats The perimeter dock and the ten piers would be supported by pilings which would be placed in the creek bottom. The permit application provides that the pilings would be installed by a process called "jetting". Sims Creek is a natural, navigable tributary of the Loxahatchee River. The mouth of Sims Creek on the Loxahatchee River is located in fairly close proximity to where a canal known as the "C-18 Canal" empties into the river. Sims Creek is a winding stream which has been relatively undisturbed by development. Petitioner's project is located approximately one thousand to fourteen hundred linear feet upland from the mouth of the creek. Approximately five hundred feet upland from the proposed docks, the creek veers sharply to the south and becomes significantly more shallow. The creek is influenced by both estuarine and tidal flows. During high tides, water flows from the Loxahatchee River upland into the creek. During low tides the water flows out of the creek into the Loxahatchee River. In addition, water generally drains through the creek into the river. The creek has good flushing characteristics. The "residence time" for water in the creek is typically one day, except in isolated pockets along the shoreline, and in deeper basins which occur in the creek. The area of the creek where the proposed docks would be constructed is a basin area. Waters reach a depth of eight feet. This area of the creek is stressed in water quality terms. Dissolved oxygen values measured at the site are in excess of Department standards. This is the result of the depth at the location; the oozy, organic bottom soils; and the fact that a storm water outfall and a sewage outfall enter the creek on the opposite side from Petitioner's property. The creek is generally more shallow than in this basin area. Near to the mouth of the creek, water depths are as shallow as 2.25 feet during high tide. The deepest continuous channel from the proposed docks to the mouth of the river is approximately three feet at high tide, and from one to one and one-half feet at low tide. The shallower areas of the creek are characterized by sandy bottoms, good water quality, and a rather high level of plant and animal activity which is diverse. Shorelines along most of the creek are dominated by mangrove vegetation. There is presently a limited amount of boating activity that occurs in the creek. Persons who testified at the hearing witnessed at various times from one to seven small motor craft in the creek. Construction of the perimeter dock and piers in the manner proposed by Petitioner in its application would have significant adverse short term water quality impacts. The "jetting process" for installing pilings would result in considerable turbidity which would be likely to violate state standards within the area of construction, and downstream to the mouth of the creek. These short term adverse impacts could be alleviated by installing the pilings through a "driving technique" and by use of turbidity screens. Petitioner has expressed a willingness to utilize these construction techniques. The proposed docking facility is likely to have an adverse impact upon water quality in Sims Creek. The project, if completed, is likely to cause violations of the Department's water quality standards. Dissolved oxygen levels in the area of the proposed project already exceed the Department's standards. The Petitioner's proposed docks would cover a significant portion of the water surface with docks, and this would exacerbate dissolved oxygen levels. Furthermore, increased boating activity in the area would, due to the interjection of greases and oils, further adversely impact dissolved oxygen levels, and can reasonably be expected to lead to violations of the Department's standards for biologic oxygen demand and oils and greases. Petitioner's proposed docking facility includes mooring spaces for approximately sixteen boats. The dock would serve therefore to increase boating activity in Sims Creek by three times or more Sims Creek is difficult to navigate without disturbing the productive shallow bottom areas. Increased boating activity is likely to disturb these areas and to lead to the destruction of a natural marine habitat. Sims Creek is too shallow a water body to sustain the sort of boating traffic that would be generated through construction of a docking facility such as Petitioner has proposed. Sims Creek is sovereignty land of the State of Florida. Petitioner has not received approval from the Board of Trustees of the Internal Improvement Trust Fund or the Department of Natural Resources to use Sims Creek in the manner proposed.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, hereby, RECOMMENDED: That a final order be entered by the Department of Environmental Regulation denying the application submitted by Landin Ltd, for a dredge and fill permit to construct a docking facility in Sims Creek, West Palm Beach, Florida. RECOMMENDED this 5th day of April, 1982, in Tallahassee, Florida. G. STEVEN PFEIFFER Assistant Director Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 5th day of April, 1982.

The Issue The issue to be resolved in this proceeding concerns whether an on-site sewage disposal system ("OSDS") construction permit should be issued to the Petitioner based upon the question of whether the property lies within the ten- year flood elevation of the Suwannee River, and if so, whether an appropriate system can be designed which will remove the system an adequate distance above the ten-year flood elevation level and thus comply with Rule 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner, Allyn B. Giffin, wishes to construct a vacation-type, part-time residence on his lot lying in Dixie County, Florida, in the vicinity of the Suwannee River. The subject proposed disposal system site lies at the Suwannee River Water Management District's river mile no. 50 and the ten-year flood elevation for that site and river mile is 21 feet above mean sea level ("MSL"). The property also lies within the "regulatory floodway" of the Suwannee River, as regulated by the Suwannee River Water Management District, and may require a "works of the district" permit. The elevation of the surface grade at the subject site is approximately 17 feet, 7 inches above MSL, as shown by the survey of Herbert Raker, a certified land surveyor. Because the property lies within the regulatory floodway of the Suwannee River, the pertinent rule requires that an engineer certify that any mounding of the system to raise it above the flood plain and the regulatory floodway level will not cause any alteration in the base flood level in that regulatory floodway of the Suwannee River. Aside from being within the regulatory floodway and beneath the ten- year flood elevation, the property is amenable to the type of subsurface septic tank and drain-field system proposed. The water table at the time of the site evaluation performed by Mr. Fross, of the Department was 72 inches below the existing surface grade. Based upon mottling in the soil, the estimated wet season water table was 42 to 48 inches below surface grade. Since the surface grade elevation at the proposed site is 17 feet, 7 inches, and the ten-year flood elevation is only 21 feet, it was shown to be quite feasible to elevate the septic tank system in a filled mound and mound pad, such that the entire system could be raised the required regulatory distance above the ten-year flood elevation level. Mr. Ted Biddy was accepted as an expert witness in the field of civil engineering with emphasis on sanitary system engineering. He testified on behalf of the Petitioner. Mr. Biddy has designed a sewage disposal system for the Petitioner, which design is admitted into evidence, which is designed to be constructed and to operate above the ten-year flood plain elevation found above. The system is called a "mounded balancing system". It will consist of a raised earthen pad with a raised mound on top of that pad containing the septic tank and drain-field system at an elevation sufficient to maintain the required regulatory differential between the bottom elevation of the drain-field trenches and the ten-year flood elevation. This system was established by Mr. Biddy's testimony to avoid any deleterious effect on public health and environmental safety which might be posed by the sewage effluent entering the system if it were placed below the existing surface grade of the lot in question. The water table elevation is at a minimum of 42 inches below the surface grade of the lot; and if the proposed system were raised above the ten- year flood elevation, the bottom grade of the drain-field trenches would be at least five feet above the surface grade elevation of the lot at the proposed installation site, plus an additional 42 inches above the wet season water table level established by the testimony of Mr. Fross, who did the site evaluation for the Department. It was thus established that such a mounded system will meet all of the parameters contained in Chapter 10D-6 and, specifically, Rules 10D- 6.044-049, Florida Administrative Code, the rules as they applied at the time of application and hearing. Dr. Richard Hunter, testifying as an expert witness for the Department, had not seen this design until the day of the hearing. Upon reviewing it, he agreed that if such a system were installed on the lot in question, it would meet all of HRS regulatory parameters and would be permittable, at least for a two-bedroom dwelling. Mr. Biddy further established that even with a three-bedroom dwelling, as originally proposed by the Petitioner, because it would only have intermittent, occasional use as a vacation retreat, the sewage loading would be substantially less than would the loading from a normal three-bedroom, full-time residence. It is also true, as found above, that the property is in the regulatory floodway of the Suwannee River. Because of this, the Department's rule requires that an engineer certify that installation of such a mounded system will not raise the base flood level of the so-called "100 year flood". This is a balancing system, as described by Mr. Biddy, which involves the removal of approximately 877 cubic yards of fill material from the site or that portion of the site which lies within the regulatory floodway. This is an amount exactly equal to the required amount of fill to construct the mounded system, as proposed. Because of this, the addition of the 877 cubic yards of fill material for the mounded system will not cause additional displacement and resulting raising of the base flood level. Thus, the Department's rule in this regard will be complied with. This is because the fill material will replace an equal amount of material excavated from the lot in that portion below the regulatory floodway level, which excavated material will be removed from the regulatory floodway entirely, thus resulting in no net gain of fill material within the regulatory floodway and, therefore, no additional displacement or elevating of the base flood level. In summary, it has been demonstrated that the addition of the mounded system, as proposed by the Petitioner through the testimony of Mr. Biddy, will not pose any environmental hazards or any potential harm to public health and safety and will result in the sewage disposal system proposed being installed at an elevation properly above the ten-year flood elevation of 21 feet above MSL. The Department has interpreted the Executive Order of the Governor, 90-14, purporting to prohibit such systems beneath the 10-year flood elevation of the Suwannee River as requiring strict prohibition of such systems in those circumstances when it carries out its enforcement of the requirements of Rule 10D-6.047(6), Florida Administrative Code, the rule applicable to this permit application, hearing and circumstances. Further, the Petitioner has agreed to limit the size of his dwelling to a two-bedroom dwelling instead of a three- bedroom dwelling.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be issued by the Department of Health and Rehabilitative Services granting a permit to the Petitioner, Allyn B. Giffin, authorizing the installation of an on-site sewage disposal system in the manner and under the conditions enumerated in the above Findings of Fact and Conclusions of Law.

Findings Of Fact The Parties The Applicant, Trail Ridge Landfill, Inc. (Trail Ridge), is a corporation formed in 1989 for the purpose of developing a landfill project and providing waste disposal capacity for the City of Jacksonville. Trail Ridge Landfill, Inc. is a wholly-owned subsidiary of Waste Management of North America, Inc. Its operating division is involved in the waste collection, recycling and disposal business. Waste Management of North America, Inc. is a wholly-owned subsidiary of Waste Management, Inc., which is involved in all facets of solid waste collection and disposal nationally. The Florida Department of Environmental Regulation (DER) is an agency of the State of Florida charged with the responsibility of regulating solid waste management facilities and with permitting their initial construction and operation. It is charged with reviewing applications for permits for construction of such facilities, for reviewing applications for dredge and fill permits in wetlands or waters of the State and, as pertinent to the project involved in this proceeding, for storm water management and storage of surface water and the regulation thereof through its permitting and enforcement authority contained in Chapters 403 and 373, Florida Statutes, and Titles 40C and 17, Florida Administrative Code. The Petitioners are Coastal Environmental Society, Inc. (CESI), a not- for-profit Florida corporation established for the purpose of protecting natural resources. St. Johns Preservation Association, Inc. (SJPA), also a not-for- profit Florida corporation established for the purpose of protecting the community, including environmental concerns; Baldwin-Maxville Coalition, Inc., also a not-for-profit corporation established to promote the health and welfare of its community, including environmental concerns; William McCranie, a resident of Jacksonville, Florida; Darryl Sperry, a resident and citizen who lives 1 1/4 miles from the proposed landfill site in Baker County. All Petitioners have been established to be substantially affected by the proposed permitting and the projects related thereto and all have met pertinent standing requirements as a matter of fact and law. The Respondents do not contest the standing of the Petitioners. Background and Purpose of the Project The purpose of the proposed landfill facility is to address the solid waste disposal needs of the City of Jacksonville and Duval County (the City). The City currently disposes of solid waste at two landfills. One is on the east side of Jacksonville on Gervin Road, and the other is located in the north area of Jacksonville on Island Road. The presently used, east landfill is an unlined landfill currently operated pursuant to a DER Consent Order, in connection with which closure of that landfill is planned. The north landfill consists of three unlined cells and one lined cell. The City currently has unused landfill capacity at these two landfills which will last approximately one more year, but has also sought approval for expansion of the north landfill which would provide about two more additional years of capacity, if approved. The proposed landfill project, if approved, constructed and operated, would meet these solid waste disposal needs for approximately 20 to 25 years. The project at hand began when the City issued a Request For Proposal for private companies to submit bids to the City for construction of additional landfill capacity somewhere to the northwest of Jacksonville in Duval County. Two companies that met qualifying requirements submitted proposals in response to the request for proposals. Trail Ridge was one of those two qualifying bidders. The City selected the Applicant for contract award and then entered into a contract. The Applicant has an option to purchase the proposed landfill site from Gilman Timber and Land Company (Gilman, Gilman Paper Company). After issuance of the permits to the Applicant, the option would be exercised. Thereafter the property would be immediately conveyed to the City from the Applicant. Thus the site of the proposed facility will ultimately be owned and controlled by the City, although the Applicant will operate the landfill under its contract with the City. Gilman presently uses the 1,288 acre site and several thousand surrounding acres for growing timber, principally pine trees, in a pine plantation-type operation grown for use as pulp wood. Much of the site and surrounding Gilman land is characterized by pine trees grown to an age of 20 years or less and then harvested. A great deal of the site property has recently been cut, chopped, plowed re-bedded and re-planted with pine trees. Although some of the site is characterized by mature timber, much of the timber has been recently planted or is otherwise timber not yet mature enough for harvest. The option agreement provides that Trail Ridge will purchase the property from Gilman for $10,000 per acre. The City will then purchase the 1,288 acres from the Applicant for $2,600 per acre, which the Applicant maintains is the current, fair-market-value for the land as it is currently used as pine plantation for growing pulp wood. These terms and conditions are a part of the City's Request For Proposals. In addition to paying the Applicant $2,600 per acre for the 1,288 acre site, the City will pay the Applicant a fee over the life of the operation of the proposed landfill. The fee, amortized over the 20- year span of the agreement, will make up the difference between the Applicant's $10,000 per acre purchase price paid to Gilman and the City's $2,600 per acre initial purchase price paid to the Applicant. The City will thus ultimately re- pay Trail Ridge the $10,000 per acre for the purchase price for the property. The Applicant corporation will operate the landfill over its entire useful life and then close it. Thus, the Applicant's own figures show the land is valued at $3,348,800. The record does not reflect the reason for the purchase price paid to Gilman being $12,880,000, of which the City will repay $9,000,000 to the Applicant in the form of the operation fee, over and above the initial payment to the Applicant of $3,348,800. In any event, the utilities payment to the Applicant of the $12,880,000 for the land and the operation of the landfill only represents the recompense to the Applicant for the purchase funds expended for it to buy the site from Gilman. Additionally, the Applicant, through its option agreement with Gilman, is required to pay Gilman a $60,000 per month option fee. $15,000 per month of that must be paid during the pendency of the option, with the remainder of the $45,000 monthly fees due upon closing of the purchase. The portion of the operation fee paid by the City over and above the $2,600 per acre initial purchase price, attributable to the land appraisal itself, will be paid by the City on the basis of a certain dollar fee-per-ton of solid waste handled and disposed of in the landfill by the Applicant. Testimony indicates this will be approximately $8.00-$15.09 per ton, although the evidence as to which amount is indefinite. The testimony of Applicant's witness Allen, in any event, references these amounts as applicable to the City's solid waste "stream" handled by Trail Ridge at the proposed facility. Its contact with the City assures the Applicant of a minimum of 569,000 tons of waste per year to which the fee would apply. The City currently generates approximately 750,000 tons of waste per year. There is no evidence of what the construction or other capital costs or operation expenses related to the proposed facility will be over the useful life of the facility for the Applicant or related corporations. Site and Design The proposed site is 1,288 acres in size, located in southwestern Duval County, approximately three miles south of Interstate Highway 10, 1.5 miles west of U.S. Highway 301 and 1.14 miles north of State Road 228. The site is located in a sparsely populated area approximately 4 to 6 miles from the City of Baldwin, 5 miles from the City of Macclenny and 2 miles from the City of Maxville. A substantial portion of the proposed site will be left undisturbed and used as a buffer area to separate it from any surrounding development. There are water supply wells within fairly close proximity to the site. One well is within a mile of the site and three are approximately 1.5 miles southeast of the site. The proposed facility will include both a Class I and Class III solid waste disposal area. The Class I area will be approximately 148 acres in size, and the Class III area, 28 acres. The Class III disposal area will only be used for non- household refuse such as construction debris, tree and shrubbery clippings and the like, which will not generate deleterious substances in liquid or gaseous form, as will the Class I landfill. The remainder of the 1,288 acres will be used for buffer zones, dirt borrow areas, storm water management facilities and ancillary facilities necessary to the day to day operation of the landfill. No part of the Class III disposal area will be located within 200 feet of jurisdictional wetlands, which are the closest bodies of water. The project will be located on "Trail Ridge," which is a relatively elevated geographic feature, extending generally in a north-south direction in western Duval County. Geologically, it is an ancient sand dune. There is a substantial decline in elevation of this portion of the ridge from west to east, which produces surface water drainage patterns in a west to east direction at the site, also accompanied by surface water drainage patterns in a southerly- northerly direction into wetlands which occur on the south and north verge of the site, because the site is a prong or easterly extension of Trail Ridge lying between wetlands which occur on the northerly, southerly and easterly boundaries of the Class I disposal site. The 1,288 acres, including the landfill sites themselves, have been used for silvi-culture practices since 1948 or earlier, and are currently managed primarily as a slash pine plantation grown for pulp wood purposes. The present owner of the site, Gilman Paper Company, plans to continue this use of the site should the landfill project not be approved and constructed. Since 1948, the entire site, including much of the wetlands thereon, have been logged, some portions of it as many as three times. The silvi-culture practices at the site include clear- cutting, chopping, burning, harrowing, tilling and bedding of the soil, and planting of pine trees. The pine trees are grown to be harvested on a 20-year cycle or less. Due to these intensive silvi-cultural practices, the natural conditions of the site have been significantly altered and much natural vegetation, such as bottom-land hardwoods, has been replaced by planted pine trees. The area has been extensively ditched for drainage purposes and logging roads have been constructed throughout the site. The design of the Class I disposal area of the landfill includes three major components: a liner system, which includes a permanent leachate collection and removal system, a cap and closure system and a gas control system. The Class I disposal area is designed to be 140 feet high when the landfill is completed and closed in approximately 20-25 years. It will have typical landfill refuse "lifts," of approximately 8 to 12 feet in height, with a side slope grade of three horizontal feet to one vertical foot of elevation gain. This is the maximum grade steepness allowed by DER rules. The Class III landfill, in which no household garbage, chemicals, oils and greases or other deleterious substances will be deposited, will include only a cap and closure system. In order to carry out Department regulatory requirements designed to contain waste permanently in a well- defined area and to minimize the amount of leachate produced within a landfill, as well as to collect and remove leachate that is produced, the landfill will have, in effect, a double liner system. The liner system is designed to contain the leachate produced when rain water contacts waste in the landfill and to cause that leachate to percolate vertically downward through the landfill, capture it in the liner system, prevent it from contacting groundwater and to remove it and treat it. Leachate from the Class I disposal area will be contained by the liner system and removed by a leachate collection and removal system. The liner system, starting from the bottom and proceeding upward, will consist of a 6 inch thick layer of compacted, subgrade soil. Over that layer, a prefabricated "bentonite" clay-like material will be deposited. Directly over the bentonite layer will be a high density polyethylene liner (the secondary liner) called a "geomembrane." The bentonite material has the characteristic of swelling when contacted by a liquid so that, if the geomembrane leaks, the bentonite will swell and plug the hole in the liner above it. On top of the bentonite layer and the geomembrane layer, is a synthetic drainage material called "geonet." Geonet has a very high transmissivity rate and therefore has great capacity to conduct water within its own plane. Lying immediately above the geonet material is a geotextile filter designed to keep sand out of the pores or interstices of the geonet. Above that geotextile filter is a second geomembrane (the primary liner). Above the second geomembrane is another geonet layer, as well as another geotextile filter layer. Then to protect the entire liner system from damage, two feet of clean sand will be placed above the uppermost geotextile filter layer. The two feet of sand also acts as a drainage layer for the uppermost geonet. The leachate that percolates down through the waste and the sand will contact the geonet and then be carried down slope on top of the geomembrane. This constitutes the leachate collection system. The bottom geonet is called the "leak detection system." This is because, if a hole develops in the primary liner, any leachate coming through the hole will be quickly drained away through the bottom geonet. The bottom geonet thus operates as a backup leachate collection system, since any leachate reaching the bottom geonet will also be discharged into the leachate removal system. If a leak should develop in the secondary liner, the bentonite material would quickly plug the leak, swelling and absorbing that liquid. The Petitioners have stipulated that the Applicant has proposed a liner system and leachate collection system for the Class I disposal area which meets all criteria of Chapter 17-701, Florida Administrative Code, except as to the requirements of Rule 17-701.050(5)(c), (e)3. and 4. and (f)3., Florida Administrative Code. The Applicant demonstrated that the liner system and leachate collection system will meet the criteria of Rule 17- 701.050(5)(c), Florida Administrative Code. The liner system will be installed in accordance with a quality assurance plan. A specific condition already agreed upon will require the Applicant to submit for approval a revised quality control and assurance plan for installing the Class I synthetic liner system, after selection of the liner manufacturer and prior to the liner's installation. The liner system is designed so that it will be protected from puncture by waste materials or landfill operation equipment. In addition to the two feet of sand placed on top of the entire liner system to protect it, when initial waste disposal begins, the first lift of waste across the entire area of the liner system, as it is installed in phases, will be composed of 6-8 feet of "select waste" to protect the liner from puncture. Select waste is waste containing no pipes, roots or other potentially puncturing objects which could penetrate the sand layer to damage the liner system. A quality assurance engineer will be on site full-time supervising the initial placement of the select waste until that phase of the landfill operation is completed. A grant of the permit should be so conditioned. The Applicant has established that the liner system and leachate collection system will meet the criteria of Rule 17-701.050(5)(e), Florida Administrative Code. The leachate depth on top of the primary and secondary liners will not exceed a foot because the geonet has the capacity to quickly remove leachate from the liner. The actual hydraulic head of leachate on the primary liner will be only approximately 1/4 inch. The depth on the secondary liner was shown to be even less. The liner system and leachate collection system will meet the criteria of Rule 17-701.050(5)(e)3. and (f)3., Florida Administrative Code. The design of the collection system, including the geotextile filter, will prevent clogging of the system throughout the active life and closure period of the landfill, primarily by placing a gravel aggregate around the collection pipe so as to prevent debris from entering the system. A pilot line will also be installed in each collection pipe to facilitate access for mechanical cleaning, should it be necessary. In the unlikely event of an obstruction in the system, the leachate would simply bypass that area and continue down-grade to the next downstream leachate collection pipe and be removed from the landfill for treatment by that means. The liner system and leachate collection system will also meet the criteria of Rule 17-701.050(5)(e)4., Florida Administrative Code. The leachate collected will be carried downhill to pipes at the east end of the landfill. The leachate will then be pumped from the pipes into storage tanks. Trucks will then be filled with leachate to be transported to the City's Buckman Regional Wastewater Treatment Plant, owned and operated by the City, for treatment and disposal. Unrefuted evidence shows that this plant has adequate capacity and treatment capability to safely treat and handle the leachate. The truck loading areas will be equipped with berms and other means of protecting the surrounding wetlands, surface and groundwaters from leachate spills during the truck filling process. The Applicant's evidence does not demonstrate, however, that the tanks themselves and the area surrounding them will have protective measures for containing leachate spills. In order to comply with the above rule, the totality of the evidence concerning the leachate collection, disposal system and treatment method demonstrates that the tanks should be accompanied by a surrounding containment system (walls or berms) which will have the capability of containing the entire capacity of a tank should failure of a leachate collection tank or related piping or valving occur. Any grant of the permit should be so conditioned. The Petitioners have stipulated, and the Department agrees, that the Class III disposal area is exempt from the liner system and leachate collection system requirements of the above-cited rule provisions. Covering and Closure System Both the Class I and Class III landfills are designed with a composite soil covering system to minimize the amount of rainfall which can come into contact with the solid waste so as to minimize the creation of leachate. During the day to day landfill operations, a 6 inch initial cover will be applied to enclose each Class I landfill disposal cell on a daily basis, except for the working face itself, where waste is currently being deposited. The working face may be left uncovered, so long as solid waste is scheduled to be placed on it within an 18 hour period. A 6 inch initial cover will also be applied once every week to enclose each Class III landfill disposal cell. Thereafter, an intermediate cover of one foot of compacted earth will be applied on top of the initial cover within seven days of initial completion, if a final cover or additional lift on top of that completed cell is not to be applied within 180 days of cell completion. The initial cover will consist of sandy soil, over which will come the intermediate cover of one foot of compacted earth. The final cover will be applied to those portions of the landfill which have been filled with waste to the extent of designed dimensions at the time those portions have been filled. The final cover, to be placed on the sides of the landfill and ultimately upon the top at the end of its useful life, will be placed on top of the 12 inches of intermediate soil layer and will consist of 12 inches of compacted clay with a permeability of 1 X 10/-7 cm/sec. Next will come a layer of 12 inches of compacted soil and then a final layer of 12 inches of top soil, upon which the Applicant will plant grass for erosion control. Erosion of the cover layers on the side slopes is designed to be minimized by closing areas of the landfill as they are filled, an operational procedure commonly referred to as "close as you go." The final cover layers placed on the landfill outside of the clay cap are designed to allow the establishment of a planted grass cover as soon as possible to minimize erosion of the cover material and the side slopes. In addition, the intermediate cover placed on top of and between each cell, beneath the clay layer surrounding the outside perimeter of the landfill, has a high permeability, thereby acting as a drainage layer to direct rainfall and leachate vertically downward to the leachate collection system, as well as to collect runoff so as to retard erosion. Erosion is also retarded, as is the runoff of storm water/leachate over the side slopes of the landfill, by containing storm water which comes into contact with the working face of the landfill cells. This will be accomplished by minimizing the size of the working face to approximately 42 feet width. This will serve to reduce the potential for storm water to contact waste. Additionally, berms will be constructed around the working faces of each active cell which will cause any runoff or storm water which gets inside the working face of the cell to remain there and to percolate through the land fill to eventually be collected as leachate by the collection system. If enough rain falls on the working face of a cell to cause an overflow of storm water over the berms, additional berms placed on the interior slopes of the landfill will catch the overflow and divert it back through the landfill and the leachate collection system. The Applicant contends that normal maintenance equipment and personnel will be able to maintain the exterior side slopes of the landfill and thus minimize erosion. However, if erosion should become a problem, the Applicant proposes to install interceptor berms constructed on the side slopes, accompanied by various geotextural fabrics or synthetic materials proposed to be imbedded on the side slopes to help anchor the interceptor berms. These berms, however, have been demonstrated by Petitioner's witness, Mr. Peavy, to be inadequate to retard erosion. In fact, they may promote erosion because they would be insufficiently anchored to the side slope (as designed with 3:1 slope) and the downhill slope of the berms themselves is considerably steeper than a 3:1 ratio, which will actually promote erosion. The erosion problem will be discussed in further detail infra, but the proposed "optional" berm system, consisting of two proposed berms down the length of the 450 foot side slope will have to be redesigned in order to serve the purpose of retarding side slope erosion. The cap or cover for the exterior side slopes of the landfill will consist of a relatively impermeable clay layer overlain by a sand layer, as well as a top soil layer. Mr. Lithman, an expert in geotechnical engineering testifying for the Applicant, established that as a result of the side slope stability analysis he conducted of the clay layer for the Class I disposal area, that the clay layer would be stable, with a safety factor of 2.9-3, which is more than adequate for a slope as designed for the Class I disposal area (3:1). Mr. Evander Peavy, testifying for the Petitioners and accepted as an expert witness in the fields of civil engineering, soil mechanics, surface water hydrology and hydraulics, agreed that there was an adequate safety factor in the clay cap layer itself and that no plane of failure would likely occur in that layer. The problem, however, lies in the sand layer immediately predetermined or potential plane of failure will occur at the interface between the sand layer and clay layer. This is where the side slope of the landfill is most likely to fail. Failure means that the weight of the sand and soil layers on the outside of the clay layer would exceed the resisting forces, holding them back on the slope of the landfill, which would result in a deformation, slumping or break in the sand layer. If this slumping or break occurs in the sand layer and is not immediately repaired, rain water can erode the clay layer, which is highly erodible if exposed to rainfall. If not redressed soon, this could result in exposure of the waste of the landfill to rain water with the result that leachate could seep out of the side slopes of the landfill and enter surface waters of the State through the functioning of the storm water system. The most likely layers a civil engineer would analyze to determine the stability of the side slope would be the sand and soil layers above the clay layer because they are the weaker layers in terms of adhesion, shearing and resistance to downward movement under stress. However, Mr. Lithman, Trail Ridge's expert who conducted a side-slope stability analysis, only analyzed failure in the clay layer initially, until he was called on rebuttal to address findings of Mr. Peavy. The DER rule provision that allows 3:1 ratio side slopes for the sides of such landfills only serves as a guideline or maximum steepness criteria for design engineers. It does not relieve an engineer from analyzing slope stability in accord with good engineering practices. Analyzing side slope stability must be done in terms of establishing "safety factors." An acceptable safety factor for a landfill is 1.5 because, if failure occurs, solid waste can quickly be uncovered which can cause leachate contamination to surface waters of the State. A safety factor of 1.5 is the commonly accepted factor for earthen dam design because of the risks posed by failure of such slopes or embankments. Mr. Peavy is extensively experienced in the design of earthen dams and similar earth works, including extensive analysis of slope constituents and design for stability under shear forces and other failure-inducing factors, as well as for resistance to erosive forces. He was engaged in such phases of engineering work for approximately 26 years, during which period he designed and oversaw construction of numerous dams, revetments and other earthen embankments and works of many types. Because of this, and because of the commonly accepted engineering methods and calculations he used in analyzing the stability and integrity of the side slopes of the landfill, involving plane of failure analysis and erosion damage analysis, his testimony is credited over that of the other witnesses testifying on the subject matters involving side slope integrity of the landfill. Because of this, a safety factor was established for the side slopes of the landfill, for the sand and soil layers of 1.5. Safety factors of 1.25 are indeed commonly used for highway embankments, but highway embankments are not designed with predetermined or potential planes of failure, such as is involved at this landfill (as presently designed) between the sand-soil layers and the clay layer. Trail Ridge's expert witness in this area, Mr. Lithman, had testified that a safety factor of 1.25 would be adequate because it was typical of DOT earthen embankments for roadways. Mr. Niehoff testified that a 1.3 safety factor was sufficient. In fact, however, Mr. Peavy, testifying for the Petitioners, calculated the safety factor of the side slopes of the landfill to actually be 0.85, using his initial assumption of a weight for a cubic foot of the sand-soil layer of approximately 100 pounds. Mr. Niehoff testifying for Trail Ridge found no basic fault with Mr. Peavy's analysis of the safety factor and alleged that his analysis was done with accepted engineering procedures, but only with use of slightly different assumptions. He testified that if he had used the same assumptions as Mr. Peavy, he would have reached the same conclusions. Mr. Peavy also calculated his safety factor again by employing the same equation used by Trail Ridge's expert, Mr. Lithman, and assumed instead that the unit of sand-soil layers was 125 pounds per cubic foot, as did Mr. Lithman. This assumption coupled with the internal angle of friction of 35 degrees used by Mr. Peavy, which was shown to be a conservative assumption, resulted in a calculated safety factor of 1.05, which is still unacceptable, even under Mr. Lithman's analysis, because Mr. Lithman opined that the safety factor should be 1.25. Using Mr. Peavy's equation, but his own assumptions as to angle of friction and weight per cubic foot of the sand-soil layer, Mr. Niehoff, testifying for the Applicant, calculated a safety factor of 1.3. This safety factor also is unacceptable because it is less than the 1.5 safety factor established as proper by Mr. Peavy's testimony and, indeed, if Mr. Lithman's safety factor of 1.25 could be deemed acceptable, the 1.3 figure would result only in a marginal safety factor at best. The major difference between the safety factor calculations of Mr. Peavy and Mr. Niehoff is that Mr. Peavy assumed that the sand-soil layer above the clay layer would be saturated, while Mr. Niehoff assumed that only 19 inches of the 24 inch sand-soil cover layer would be saturated by rainfall. However, Trail Ridge's own experts, Mr. Lithman and Mr. Niehoff, offered conflicting testimony between themselves on the amount of saturation to be expected. Like Mr. Peavy, Mr. Lithman did his analysis on the basis that the sand-soil layers would be saturated completely, contrary to Mr. Niehoff's subsequent testimony that this would not happen beyond a 19 inch depth in the layer. Mr. Niehoff's conclusions that the sand-soil layer would not become saturated or valid only if there is a complete grass cover over the entire side slopes of the landfill. He admitted that if the sand-soil layer became saturated, the safety factor would only be 1.1 or less according to his own calculations. Trail Ridge offered no preponderant evidence to establish that an adequate grass cover could be established so as to prevent saturation of the sand-soil layer during the design 25-year, 24-hour storm event (approximately 8- 9 inches rainfall in 24 hours). The evidence indicates, rather, that establishing and maintaining a grass cover on the side slopes of the landfill will be very difficult to achieve on a uniform, completely grassed basis. This is because of erosion and because of the damage by equipment necessary to repeatedly repair erosion damage and because of the fact that much of the side slopes of the landfill will be, in effect, under construction until the landfill is completely built out and completed at the end of approximately 20 years. Even if the lower several lifts of the landfill, when covered on the "cover as you go" basis can achieve them, more recently deposited, will not have a complete grass cover. Thus, there is a substantial likelihood of saturation of the sand-soil layer, during storm events of the type for which the landfill is designed. Further, the volume of water that would saturate into the sand-soil layer, even if the landfill was completely grassed, will still be sufficient to totally saturate the lower 90 feet of the landfill side slopes above the clay layer in the event of a 25-year, 24-hour storm event. If the sand-soil layers become saturated, sloughing or failure of those layers will occur at the toe of the landfill. If that occurs, then the clay layer, protective cap can be quickly eroded by subsequent rainfall and surface runoff. This will cause the waste within the landfill to be exposed to rainfall, generating leachate which can migrate to the surface of the landfill and thence to the storm water system and ultimately to the surface waters of the State. No provisions have been made in the design to remove water from the sand-soil layers once it reaches the area near the toe of the landfill to prevent sand-soil layer failure. The impermeability of the clay layer would prevent the rainfall from migrating through the clay layer and continuing to the interior bottom of the landfill to be collected properly as leachate because the clay layer properly should be an impermeable barrier to storm water. Thus, a saturated condition of the sand-soil layers would be most likely to cause their sloughing and failure near the toe of the landfill, with resulting damage by erosion or cracking to the clay layer with the effect of allowing leachate to escape to surface waters of the State. Although the Applicant's expert, Mr. Lithman, opined that side slope stability had not been a problem with the 3:1 ratio slopes at the City's Rosemary Hill Landfill, he admittedly was unaware of the height or length of the side slopes of that landfill. The longer the side slopes and the higher the landfill, the more likely it is that the sand-soil layers will become saturated and fail during design storm events or shortly thereafter, especially as the landfill, in its later years is built both longer and higher toward its final configuration. Further, Mr. Lithman and the Applicant's evidence does not reveal the composition of the side slopes of the Rosemary Hill Landfill, in terms of whether or not the clay and sand-soil layers designed in the proposed landfill are present. Due to the height of the proposed landfill, the lengths of its side slopes and the absence of design features such as terraces and benches, failure of the side slopes, especially in the later years of the landfill's life and, indeed, after closure (closed landfills can generate leachate) is likely to occur, based upon the facts established through Mr. Peavy's testimony. The likely side slope failure is a result of the design flaw and is not a problem which can be cured by normal operation and maintenance activities. Indeed those activities may aggravate the problem through their deleterious effect on the establishment of a uniform, complete grass cover. Because of the height of the proposed landfill, the length and slopes of its sides and the lack of design features such as benches or terraces, it is likely to experience significant side slope erosion due to storm water. The volume of rain water that would accumulate and flow down the sides of the landfill will achieve velocities which would destroy even a well established grass cover, especially in the later years of the landfill's life when the sides have reached significant length and height. Storm water would thus gain sufficient velocity to destroy a grass cover and to particularly attack those portions where the grass cover is incomplete, thinned or possessed of an insufficient root mat to hold the soil. Once erosion starts, small rills will form which will soon develop into deeper gullies, ultimately penetrating the sand-soil layer. It can then quickly erode away the resulting exposed clay cap layer, exposing the waste to storm water. Leachate could thus leak from the landfill. Because of the present design of the Class I landfill, the only way to repair erosion damage is to push material from the bottom with heavy machinery, such as bulldozers. These erosion maintenance activities themselves would prevent the establishment of a uniform solid grass cover. The presently operated East Landfill in Duval County exhibits both side slope failure and erosion damage due to rainfall on its 3:1 slopes, including damage to the grass cover. Erosion damage to the slope layers due to erosion maintenance activities of the type which would be necessary to repair damage at the proposed landfill has occurred. Both erosion and side slope failure will ultimately result in exposure of solid waste to rainfall runoff and assure side slope seepage of leachate. The material eroded or sloughed away from the side slopes can obstruct the drainage conveyance system surrounding the landfill, rendering the MSSW/storm water system inoperative. Because of the presently proposed design of the landfill, it would be impossible to effectively correct side slope erosion or failure, due especially to maintenance activities. Even if a uniform grass cover could be established in the last years of landfill operation and after closure, the great length and slope of sides of the landfill by that time would result in erosion even if the grass cover were initially uniform and solid on the entire slope of the landfill. A change in the design of the landfill, however, whereby 15 foot wide benches or terraces would be incorporated into the sides of the landfill every 20 or so vertical feet, would likely prevent the side slope erosion and failure established to be likely by Mr. Peavy. In fact, benches or terraces similar to those found to be required by Mr. Peavy have had to be recently installed at the East Landfill in Duval County in order to resolve side slope erosion and failure problems on those 3:1 slopes. The mere installation of interceptor berms, as depicted in TRL Exhibit 28, would not alleviate side slope failure and erosion problems, but rather would aggravate them and would reduce the safety factor of the side slopes to 0.5. Consequently, in order to grant the permit, it should be conditioned on the landfill being re-designed and constructed so as to incorporate benches or terraces at approximately 20 foot intervals on the slope of the landfill from bottom to top. Although this may potentially reduce the volume of space within the landfill, depending on how it is accomplished, it has been established that, without the use of the bench or terrace system, pollutant leachate cannot be reasonably assured to be prevented from entering State waters and wetlands. Leachate Control Leachate is any water coming in contact with solid waste. The chemical constituents of leachate which are present and will be present in the Duval County solid waste stream, to be disposed of at the proposed landfill, include chlorobenzene, volatile organics of various types, benzene, acetone, phenolic compounds, gasoline constituents, chloroform, methylethylketone, methylene chloride, toluene, xylene, ethylbenzene, total organic carbon, nitrogen, phosphorus and metals such as aluminum, chromium and zinc. Leachate thus contains toxic, hazardous and priority pollutants which will be disposed of in the landfill. The breakdown and degradation of solid waste can also generate additional toxic or hazardous compounds and substances. Leachate can potentially be discharged in a proposed landfill into groundwater and surface waters in a number of ways, including leakage from the bottom of the landfill liner into groundwaters, including into the Class I storm water pond and surface waters of the State through discharge from the groundwater into the storm water pond system. It could also be deposited into the storm water system through spillage of leachate where tanker trucks are loaded, through seepage of leachate through the side slopes of the proposed landfill by damage to the integrity of those side slopes as found above. The Petitioners maintain that side slope seepage of leachate will occur because the permeability of the intermediate cover layers surrounding the cells of the landfill is significantly less than the permeability of solid waste. This will have the result, according to Petitioners, that leachate will migrate horizontally through the intermediate cover layers to the sides of the landfill. Once there it arguably would migrate to the surface of the landfill side slopes through erosion of the outer cover, and fissures in the clay due to drying from exposure to the sun and through erosion. Additionally, the Petitioners maintain that leachate will migrate downward through the peripheral intermediate cover layer under the clay and contact the impermeable clay anchor cap, build up hydraulic head pressure and thus seep out through landfill sides near the toe of the landfill. The Petitioners maintain that Trail Ridge's policy and proposal to punch holes in the intermediate cover layers atop the cells of the landfill to encourage downward migration of leachate and discourage horizontal migration of leachate through the intermediate cover layers will be ineffective because the intermediate cover is more permeable than the solid waste itself so that punching holes in the intermediate cover to allow the leachate to migrate down through solid waste will actually not occur. Additionally the Petitioners contend that the filter system and the storm water pond will not treat the dissolved chemical components of the leachate specified in Petitioner's Exhibit 2 and that these dissolved components will move through the sand filters into waters of the State. Contrary to Petitioner's contentions, however, the Applicant has demonstrated that leachate will not avoid capture by the leachate collection system by seeping horizontally through the cover or cap and out the sides of the landfill, provided that the side slope failure and erosion prevention measures found to be necessary in the above Findings of Fact are instituted in the design, construction and operation of the landfill. The design of the cap and closure system is basically a side slope seepage prevention system, except for the absence of terraces or benches. The intermediate soil cover beneath the clay cap and surrounding each cell of the landfill acts as a drainage medium. It will channel any seepage of leachate from the cells of solid waste through the permeable, intermediate soil cover, generally in a downward direction, both in and between the cells of the landfill throughout its cross-section, as well as downward through the intermediate soil cover lining immediately beneath the clay cap around the periphery of the landfill. This system, if the above design deficiency is corrected, will tend to force the leachate downward into the collection system, as opposed to horizontally out the cover or the sides of the landfill. The reason this system will work in this manner is because the intermediate cover soil is more permeable than the solid waste itself. The permeability of the intermediate cover will promote vertical movement of the leachate because, as the leachate migrates across each cell, it will encounter the vertical, intermediate soil cover layer at the side of each cell and that will promote its moving downward toward the collection system. The water in the landfill will thus follow the path of least resistance, so that the vertical portions of the intermediate cover layers surrounding each cell and surrounding the sides of the landfill beneath the clay cap, coupled with the force of gravity, will provide a preferential path downward toward the leachate collection system. This finding includes consideration of the Petitioners' contention that leachate will migrate downward and contact the impermeable clay anchor cap and build up head pressure so that it will seep out of the sides at the toe of the landfill. The intermediate cover layer underlying the sides of the landfill beneath the clay anchor cap is connected with the leachate collection system underlying the bottom of the landfill. Thus, a continuous conduction of leachate down through the intermediate cover, permeable layer will allow the leachate to seep downward all the way to the leachate collection system rather than pooling behind the impermeable clay anchor cap. This condition will be enhanced by the fact that surrounding each cell is the approximately vertical, permeable intermediate cover layer, throughout the entire cross-section of the landfill, such that much of the leachate will migrate downward in the interior of the landfill. Because of the ready conductance of leachate in a downward direction by the intermediate cover layers, Trail Ridge's policy of punching holes in the intermediate cover layer on the top of each cell in order to seek to prevent side slope seepage of leachate will be ineffective because the intermediate cover is more permeable than the solid waste. Thus, this procedure is unnecessary and, in fact, could become counter-productive to the extent that punching holes in the intermediate cover would allow rain water mixed with leachate to contact more of the solid waste contents of the landfill as it migrates down through the interior of each solid waste cell. This would result in a more highly concentrated form of leachate, which could pose more deleterious threats to ground and surface waters should it escape to ground and surface waters. Therefore, any grant of the permit should be conditioned on a prohibition of the Applicant thus violating the integrity of the intermediate cover layer overlying each cell as the landfill is built up in lifts. Gas Control System The Class I disposal area is designed with a gas control system which will prevent explosions and fires caused by the accumulation of methane gas due to decomposition of the waste in the landfill. The gas control system will prevent damage to the vegetation on the final cover of the closed portions of the landfill or vegetation beyond the perimeter of the property. It will prevent objectionable odors off site. The Petitioners have stipulated that the Applicants' gas control system will be designed in accordance with Rule 17- 701.050(5)(j), Florida Administrative Code. Although the Petitioners presented testimony of various persons who live in close proximity to other landfills, which were at one time operated by Waste Management subsidiary companies, neither the persons who testified of odor problems at those landfills, nor other witnesses presented testimony to show whether any of the landfills utilized a gas control system or one of equivalent design to that proposed for the subject facility. No evidence was presented to support a finding that the proposed landfill facility would produce objectionable odors to any significant degree. The Petitioners have further stipulated that the Class III disposal area is exempt from the gas control system requirements set forth in Rule 17- 701.050(5)(i) and (j) and (6)(i), Florida Administrative Code, and the Department agrees. Hydrogeology and Ground Water Monitoring The Applicant filed as part of its application, and placed in evidence, a hydrogeological survey and groundwater monitoring plan, contained in TRL Exhibit 51. The hydrology of the proposed landfill site may fairly be characterized as complex because it contains many different features such as recharge and discharge areas, varying zones of conductivity, a sand component to the surficial aquifer as well as a rock aquifer component and multi-directional groundwater flows. Additionally, wetland systems occur down-gradient from the higher levels of the surficial aquifer on the north, east and south sides of the proposed Class I disposal area. From the surface grade down to a depth of approximately 100 feet lies the surficial aquifer, which primarily consists of a coarse sand medium. Lying below the sand aquifer is a confining unit (relatively impermeable) identified as the Hawthorn Group, which consists of denser marls, dolomites and silver clays. Beneath the Hawthorn layer, at a depth of approximately 300-400 feet, is the Floridan aquifer, which serves as the principal deep water supply source for this part of Florida. Additionally, immediately above the Hawthorn layer in the deep zone of the surficial aquifer, a "rock aquifer" exists under a portion of the landfill site, generally the eastern-most portion. It was not shown to be continuous throughout the site. The rock aquifer is connected to the sand surficial aquifer lying above it. Zones of varying higher and lower permeability occur at various places within the surficial aquifer. Generally, groundwater at the site flows down-gradient in an easterly direction, caused by rain or surface water recharging the surficial aquifer on the higher portions of Trail Ridge, including the western side of the landfill Class I disposal site. The surficial aquifer then discharges this groundwater to the land surface and the wetlands lying on the eastern side of the site. Additionally, some northward and southward flow of groundwater occurs from recharge areas to the wetlands lying on the northerly and southerly boundaries of the Class I disposal site in the wetlands. The specific condition 19 contained in the Department's Notice of Intent to issue permit and draft permit requires the Applicant to periodically (quarterly) sample monitoring wells to ensure that water quality standards are not exceeded at the boundary of a zone of discharge established by that specific condition and authorized by Rule 17-28.700(4)(a), Florida Administrative Code. A groundwater monitoring plan has been developed by the Applicant, with accompanying hydrogeological survey as mandated by Rule 17-28.700, Florida Administrative Code. The proposed groundwater monitoring system consists of 42 monitoring wells in and around the area of the proposed Class I and Class III landfill sites. The system is designed to monitor upgradient and downgradient flows in wells constructed to sample from the shallow and intermediate zone and from the deep zone (to some extent) on the east boundary of the Class I disposal site. Specific condition number 18 of the Notice of Intent to grant the permit and draft permit, to which the Applicant has agreed, requires that a detailed chemical characterization of a representative sample of leachate be performed, so as to allow for any necessary modifications to the list of chemical substances to be analyzed in water samples drawn from the monitoring wells on a quarterly basis. Although there are up-gradient monitoring wells for the shallow and intermediate portions of the surficial aquifer, there are no upgradient monitoring wells for the deep zone of the surficial aquifer. There are no upgradient monitoring wells on the west side of the landfill in the deep zone. The deep zone of the surficial aquifer is the zone between the intermediate zone and the top of the Hawthorn confining bed. The rock aquifer is present beneath the proposed landfill site and was encountered at well locations B-7, B-8, B-12 and B-14. That rock aquifer is hydrologically connected to and part of the deep zone, which is hydrogeologically connected throughout the site to the uppermost portions of the surficial aquifer lying beneath the landfill. The rock aquifer is a significant source of drinking water in Duval County and the surrounding northeast Florida area and is used as a supply source for domestic and commercial wells within one and one-half miles of the landfill Class I site. "Sinkers" are immiscible liquids contained in landfill leachate that are denser than water. When released from the landfill they would sink to the first low permeability unit in the surficial aquifer. This would be at the bottom of the surficial aquifer at the rock unit. Once they encountered a lower permeability unit or strata, sinkers would then move in a more lateral direction downgradient in undetermined directions. The silty clay layer depicted on Figure 9 of TRL Exhibit 51 would intercept those sinkers and cause them to tend to move in a direction toward the silty clay layer intercepted by well B-1. At that point the sinkers would then have a tendency to move in a north or south direction on top of the confining zone. The direction those sinkers would move, following a gradient, cannot be determined at present from the groundwater monitoring plan because no deep wells are proposed in either of those areas which could detect sinkers. The groundwater monitoring plan is thus not adequate for the deep zone or to detect pollutants that could migrate off site in the rock aquifer because there are no monitoring wells in the deep zone on the west, north and south sides of the Class I landfill area. Monitoring for sinker compounds in the deep zones is thus insufficient and water supply wells nearby in the deep zone would be at risk because there is no way to detect pollutants between those water supply wells and the source of the pollutants at the landfill. The groundwater monitoring plan is inadequate because there is insufficient information to determine the direction of water flow in the deep zone. Sufficient upgradient monitoring wells in the deep zone are necessary in order to determine the direction of water flow in the deep zone which will in turn indicate where additional deep zone monitoring wells should be located to detect contaminants migrating off site. Leachates also contain contaminant constituents or compounds called "floaters." Floaters are immiscible liquids which are lighter or less dense than water. They tend to float on top of the groundwater table. The hydrologic information depicted with the application and the Applicant's evidence is not sufficient to determine where floaters might migrate. The shallow monitoring wells referenced in TRL Exhibit 42 would not adequately detect floaters at or near the water table surface. Due to the lower lying stream or wetland systems on the north and south side of the Class I landfill on Trail Ridge, groundwater flows in the vicinity of those areas are likely moving northward and southward to some extent. Thus, TRL Exhibit 51, and particularly Figure 14 of that exhibit, is insufficient to support a determination of where monitoring wells should be located because it does not include the impact of the stream or wetland systems on the north and south sides of the landfill. Groundwater contours bend into the stream areas on the north and south sides of the landfill which would indicate groundwater flow to the south and the north instead of just from west to east. The general shape of these contour lines would resemble the contour lines depicted in Figure 16 of TRL Exhibit 51. These contour lines bend back to the east and the west on the north and south sides of the Class I landfill. Since there is groundwater flow to the north and to the south from the Class I landfill, intermediate and deep monitoring wells in addition to shallow wells, should be located along the west, north and south sides of the landfill. Because they are not in the groundwater monitoring plan thus far, the plan is inadequate. A grant of the permits should be conditioned on such additional wells being installed and made a part of the monitoring program, in accordance with the above findings. A zone of discharge for the proposed landfill has been established pursuant to Rule 17-28.700(4)(a)2., Florida Administrative Code, which is intended to extend vertically from the base of the surficial aquifer and horizontally 100 feet beyond the footprint of the landfill or to the compliance groundwater monitoring wells, whichever is less. (See pages 611- 618 of the transcript.) Therefore, even if the groundwater monitoring wells are closer than 100 feet to the footprint of the landfill, they are to be used for monitoring for compliance with applicable water quality standards, including the primary and secondary drinking water standards for G-II groundwater, as contained in Rules 17-550.310 and 17-550.320, Florida Administrative Code. The Applicant has agreed to this location of the wells, their spatial relationship to the footprint of the landfill, to the zone of discharge and to their use for compliance purposes. Storm Water and Surface Water Management System The Applicant proposes as part of its permit application a storm water discharge and surface water management system. The application for permitting for that system was submitted to the DER which reviewed it using the Water Management District's permitting criteria set forth in Chapters 40C-4 and 40C- 42, Florida Administrative Code. Pursuant to its independent permitting authority set forth in Section 373.413, Florida Statutes, the DER noticed its intent to issue the MSSW permit to the Applicant, based upon its opinion that the project will comply with applicable rules. The proposed storm water discharge/surface water management system (MSSW system) will utilize roadside swales, perimeter ditches, catch basins, culverts, detention ponds and pump stations to manage storm water in compliance with Chapters 17-25, 40C-4 and 40C-42, Florida Administrative Code. The solid waste disposal areas will operate as watersheds, routing storm water in to the MSSW system. The retention areas have been designed to handle the retention treatment requirements of a 25-year, 24-hour "design storm" runoff, resulting from approximately eight to nine inches of rainfall. The system is comprised of three independent parts; the Class I landfill system, the Class III landfill system and the separate roadway surface water management system. The Class I system will use temporary berms to intercept storm water runoff from the cap cover system of the landfill, on top of the solid waste disposal area. These top berms will divert the storm water runoff to regularly spaced pipes which will convey the storm water into the perimeter swale located at the foot of the landfill side slopes. The runoff will then be diverted through a culvert into a concrete-lined perimeter ditch which will convey it to the pond. The top berms of the landfill also operate as erosion control features, capturing and channelling some storm water runoff away from the side slopes of the landfill, thereby assisting in erosion control. The Class I retention pond covers an area of approximately ten acres and will contain approximately 43 million gallons of water at design water levels. The peak flow of storm water runoff from a design 25-year, 24-hour storm can be accumulated and released at predetermined rates. The runoff from the first one inch of rainfall in a 72 hour period is retained and stored in the pond. No discharge will be allowed to the pond's outfall system, rather all the outfall from the runoff from the first inch of rainfall will be routed through the sand filter system prior to discharge. When storm water runoff enters the pond, it will mix with the water already in the pond and become part of the total water column. When a rainfall event then produces greater than one inch of rainfall, some water will have to be discharged from the pond by passing it through the sand filter and then discharging through the outfall structure. The water discharged is water which was already resident in the pond before the rainfall event, mixed with the current rainfall runoff from that hypothetical rainfall event. The volume of the pond is so large that storm water runoff will constitute a very small fraction of the actual water volume in the pond at any given time. On the average, it will take 33 days for a given molecule of storm water runoff to travel through the pond, the sand filter and then be discharged through the outfall system. the sand filter system operates on a water level trigger device involving floats in wet wells attached to electrical switching mechanisms. When a certain water elevation in the wet wells, reflective of the elevation in the pond, is reached, the pumps automatically start and pump water into the filter chambers, causing the water to flow over a filtering sand. The filter will be maintained periodically by lowering of the water level to permit removal and replacement of the top six inches of sand in the filter. The Class III storm water pond is similar in design to the Class I pond except that it will not use a top berm. Rather, a perimeter swale will function similarly to the Class I landfill top berm, intercepting storm water runoff from the top and side slopes of the Class III landfill. The Class III storm water pond is equipped with the same type of filtration and pumping system as the Class I pond. The Class III system is designed also to retain the first inch of storm water runoff from a "design storm" rainfall in a 72 hour period. All of that runoff from the first inch of rainfall will likewise be routed through sand filtering prior to discharge. The roadway storm water system utilizes grassed roadside swales to act as a retention structure to filter the storm water runoff. The runoff retained in the swales will be conveyed by pipe to a smaller detention and dispersion pond located between the Class I and Class III disposal areas and built with the same design constraints as the Class I pond. The roadway system will not use a pumping system to operate, but rather discharge will occur through natural action of gravity through the dispersion pond. The filtered storm water runoff from the Class I and Class III disposal areas will be discharged into adjacent wetlands after it leaves the ponds. The discharge will be performed by a wetland irrigation system. The irrigation system will discharge the filtered storm water through conveyance pipes to the wetland boundaries. There a series of perforated pipes will extend outward from the conveyance pipes themselves and serve as a means of gradually releasing the filtered storm water into the wet land area as a means of wetland replenishment and mitigation. Concerning the issue of surface water quality, it has been established that the sand filtering systems on the Class I and Class III storm water ponds are capable of providing 100 percent of the treatment required by State water quality standards when considered in conjunction with the treatment capability of the ponds themselves as natural lake systems. The individual sand filters each provide twice the capacity for treatment necessary which equates to a safety factor of 2. With both filters operating, there is a combined safety factor of 4. Although the Class I and Class III retention ponds are designed with filtration systems, the primary pollution removal system will be the ponds themselves operating as natural lakes. Once storm water enters the ponds, the average residence time is adequate to allow the biological processes of uptake and assimilation to function to remove the bulk of the pollutants, including those derived from any spillage of leachate into the storm water management system and ultimately deposited into the ponds. The volatile organic compounds which can occur in the leachate can largely be removed simply by the process of evaporation, due to the adequate retention time of any leachate- containing storm water which reaches the ponds. It has been established that, due to the storm water pond's natural treatment mechanisms, especially the long retention time, the size and volume of the ponds, as well as the vegetated sides of the ponds, that, considering also the operation of the filter system, the water discharging from the Class I and Class III storm water treatment facility will have very low concentrations of total nitrogen, phosphorous, biochemical oxygen demand (BOD), suspended solids and heavy metals. The Applicant's expert witness on water quality and water chemistry, Dr. Harper, also assumed that the Class I retention pond would have some leachate migration into the pond through groundwater influx. Worst case scenarios were used to estimate this possible influx and the results established a maximum deposition of 2.46 gallons of leachate into the pond over a 65 day period. This amount would be diluted by a factor of 14 million solely by new storm water runoff and rain normally expected under average rainfall conditions during such a 65 day period, without even considering the considerable dilution by the existing water volume of approximately 43 million gallons already in the pond in such a period. Dr. Harper's testimony is accepted. It is unlikely that any runoff can enter the retention pond on one day and then exit within one day's time through the outfall overflow device. Even assuming that runoff occurs in excess of the designed one inch, that runoff would dilute with the large volume of water already present in the storm water pond. Thus, the new storm water would be mixed, diluted and subject to natural biological processes and the process of evaporation (of volatile organic compounds), operative in the pond before it can be released through the outfall structure. The runoff will enter the pond at the west end and discharge through the opposite or east end of the pond. The majority of water caused to be discharged through the outfall because of a larger-than-design storm event runoff would thus actually be water already present in the pond as opposed to incoming runoff from the recent rain event being deposited in the west end of the pond where the storm water system discharges from the Class I disposal area. Even a rainfall event producing twice the designed-for volume would produce no effect on the water quality of the discharge. Further, along with the filter systems and the natural processes of biological uptake, assimilation as well as evaporation in the natural lake system which would operate in the pond, the side slopes of both ponds will be vegetated so as to further assist in uptake and removal of any pollutants present in the runoff, further mitigating any potential for water quality impacts. It has been established that the surface water management system is designed to segregate surface water from leachate by minimizing the size of the landfill working face and reducing the potential for storm water to contact waste and become leachate. Further, a berm will be constructed around each working face which will encompass the entire active cell of the landfill, causing any runoff water entering the working face to remain there and percolate through the landfill to the leachate collection system, rather than entering the storm water system. If a severe rainfall event could cause leachate to overflow those berms, the design includes additional berms on the interior slopes of the landfill to catch that overflow and divert it back through the leachate collection system. The berms are relocated as the working face of the landfill changes, so they will continue to fulfill these functions on an ongoing basis. In terms of a worst case event, the Applicant has also established that the estimated impact of runoff from approximately one acre of exposed solid waste entering the retention pond would still cause no water quality impacts. Further assurance of leachate segregation from surface waters is provided in a spillage control plan which would be activated in the event of leachate spillage from a tanker truck. In connection with this, any grant of the permit should be conditioned upon an adequate berm system surrounding the tank truck leachate filling device in order to contain any such spill to prevent the leachate from entering the storm water retention facilities and surface waters. Such a system should also be characterized by (and the permit conditioned upon) retention berms or other forms of containment being placed around each leachate storage tank, designed to retain the full capacity of such a leachate storage tank in the event of a catastrophic tank valve, piping or other failure. It has been demonstrated, moreover, that if the leachate-storm water separation and control system were to fail in some way so that leachate directly entered the retention pond, the volume of leachate entering the pond would have to exceed approximately 150,000 gallons to cause any water quality violation in the storm water retention pond, even assuming the high concentration of contaminants in the leachate envisioned in the opinion of Dr. Robert Livingston, the Petitioners' aquatic ecologist and toxicologist. He raised concerns that pollution of the head water systems of the St. Johns and St. Mary's Rivers might result from the operation of the project. The Applicant has rebutted the concerns expressed by Dr. Livingston and Dr. Parks and established reasonable assurances that toxins and contaminants occurring in leachate will not deposit in surface waters of the State in any significant or rule-violative amounts for the reasons expressed in the above Findings of Fact. Draw-Down Effects The Petitioners contend that there will be a draw-down of groundwater levels in surrounding wetlands caused by these storm water ponds and associated pumping, in violation of the Water Management District's rules and policy embodied in MSSW Handbook Section 10.6.3. This section presumes an adverse impact on wetlands will result if the system causes the groundwater table to be lowered more than five feet lower than the average dry season low water table. The Petitioners' expert in this area, Dr. Motz, estimated that a measurable draw-down of groundwater of one to two feet in the wetlands water table would extend outward as far as maybe 1,000 feet in all directions from each of the storm water ponds. Dr. Motz used a large error convergence factor in his calculations, however, and also used a model for a confined aquifer, which was not shown to exist at the subject site. He did not use a model which should be appropriate for unconfined or semiconfined aquifers which the evidence reveals is the more appropriate hydrogeology which would be employed in groundwater modeling for the subject site. Dr. Motz' use of a large error convergence factor can potentially result in an answer which is far from the actual appropriate draw-down figure. Numerical models are approximations of reality and the smaller the error convergence factor, then the closer to the real number of the cone of depression, or draw-down level, the model will give. Consequently, the use of an analytical groundwater, cone of depression model was shown by the Applicants' witnesses to give a more accurate result, especially in view of the large error convergence factor employed by Dr. Motz in his numerical model. It was not shown that Dr. Motz had actually "calibrated" the groundwater model he employed. The Applicants' hydrogeology expert, Don Miller, used three analytical and two empirical methods to determine radius of influence or draw-down from the storm water ponds and calibrated the models he used. Validating the data or calibrating the model is a way of making sure the model actually represents the situation intended. Calibration is performed in this instance by inputting some data and then seeing if the model itself could accurately predict the remainder of the data of interest. Using these various methods, Dr. Miller arrived at a range of radius of influence likely to occur from the Class I storm water pond of 167 feet to 184 feet at the western end of the pond and approximately 40 feet at the eastern end. The maximum radius of influence for the Class III storm water pond was shown to be approximately 160 feet at the western end and 0 at the northeastern corner. The other hydrogeology expert for the Applicant, Dr. Leve, performed a separate analytical analysis of draw-down using the Southwest Florida Water Management District's "KOCH" model to produce a projected radius of influence of approximately 167 feet, which is comparable to the projections of Dr. Miller. In conjunction with this, it was shown that Dr. Motz' use of a small value for groundwater infiltration and the large error convergence factor served to increase his predicted radius of influence in an inaccurate way. Dr. Motz also used a higher value for transmissivity or hydraulic conductivity ("K"). The Applicant's experts relied on the average of the actual permeability test results obtained for the site. A different figure for transmissivity or hydraulic conductivity results from Dr. Motz taking into account two test wells in which hydraulic conductivity could not be measured because the well water level rose too quickly to obtain a measurement. Consequently, he predicted or assumed that that factor might affect the hydraulic conductivity at the site by a whole order of magnitude, which resulted in his 1,000 foot prediction for draw-down cone of influence. The problem here is that the evidence does not demonstrate clearly that this much- greater hydraulic conductivity factor with regard to these two wells, which was an isolated incident compared to all other wells tested, is not some mechanical or human error in the installation or evaluation of the wells. Further, even if one predicts the hydraulic conductivity of the unmeasured, apparently highly conductive wells at the geometric mean of all the hydraulic conductivity measurements for the water table zone (except for the marl zone) at 3.0 X 10 cm/sec or three times greater than the value used by the Applicant, it would result in a cone of influence of 265 feet instead of 184 feet. If one also assumed a value for the two ignored wells, as data points, by assuming that they had a hydraulic conductivity value of 3.5 x 10/-3 cm/sec, the highest reported well conductivity value, and then employed that in the empirical formula used by Donald Miller, it would still not greatly exceed the 265 foot cone of depression number. No evidence was adduced to demonstrate that a cone of depression of that magnitude would have any adverse affect on the wetlands, especially in view of the recharging of the wetlands through the storm water pumping and irrigation system. In summary, the totality of the evidence in the Applicant's case, especially on rebuttal, demonstrates that Dr. Motz' methodology significantly overestimated the radius of influence for draw-down at both storm water ponds. The parties agree that the maximum draw-down of 16 feet would occur within the Class I storm water pond, where a "seepage face" would be formed where the pond would cut into the water table through earth borrowing activities. The maximum draw-down inside the Class III storm water pond, where a seepage face would be formed by the excavation into the water table to construct the pond, will be 14 feet. The lowered groundwater within the storm water ponds is due in part to the natural sloping land surface of that area and the concurrent natural slope of the water level before the ponds are even excavated. The slope of draw-down will decrease rapidly, that is, much of the 14 foot or 16 foot apparent draw-down amount will be the result of the relatively sheer seepage face formed by the pond excavation. At the top of that seepage face, the groundwater cone of depression will flatten out considerably and very rapidly so that, as the slope of the draw-down decreases rapidly in the immediate vicinity of the pond, the groundwater outside the ponds themselves will actually be lowered less than five feet. The groundwater levels used in the application were based upon seasonal high water level for the site, rather than "average dry season low" water levels, as referenced in Section 10.6.3 of the Water Management District's Applicant's handbook. Therefore, the projected draw-downs are very conservative and would overestimate the actual draw-down for dry season low water table groundwater levels. Consequently, the weight of the evidence supports the Applicant's predictions on the effects of draw-down. The evidence demonstrates that draw-down from the storm water ponds associated with both landfills will have either no impact or minimal impact on wetland species, either transitional or submerged, in the surrounding wetlands. Silvi-culture activities on the site have considerably altered the area and lowered the natural water table through the construction of drainage structures by the timber company in the past. In general, the wetland jurisdictional lines from the storm water ponds are based on United States Army Corps of Engineers (Corps) wetland criteria and thus do not contain species generally considered to be wetland species for purposes of DER dredge and fill or Water Management District MSSW jurisdictional purposes. Many species used by the Corps in determining jurisdiction, such as slash pine, can grow both in uplands or wetlands. The edges of the areas delineated as jurisdictional wetlands are dominated by transitional and upland plant species such as slash pine, gallberry, palmetto, grapevine and huckleberry, which can tolerate dry conditions. It is only as one's investigation proceeds waterward or toward the center of the delineated wetlands, (in which area the land surface slopes down- gradient at the same area where the draw-down cone of influence rapidly diminishes to an insignificant level), that the plant species change to those species adapted to regular and periodic inundation for purposes of the State agencies' wetlands jurisdiction. The draw-down maximum for any wetland location using the maximum projected radius from Dr. Miller's efforts of 184 feet, (17 feet beyond the projection based upon the Water Management District's model), is on the southwest edge of the Class I pond. Maximum draw-down there will be 24' inches at the wetland boundary line, that is, the Corps jurisdictional boundary line where the dominant plant species are transitional or upland plants such as slash pine, gallberry and bay trees. Pine trees at this point exhibit tall and vigorous growth which indicates that the water table, before installation of the ponds, is already well below the surface, otherwise these upland trees would lack sufficient oxygen to grow if water levels were closer to the surface. The potential draw-down here would thus have little effect on this vegetation. There will be essentially no draw-down effect further down-gradient beyond the DER Water Management District jurisdictional boundary, where the pines are already of diminished stature because of water existing close to the land's surface and where DER wetland jurisdictionally-listed plants predominate. The draw-down at the wetland boundary line on the southeastern part of the Class I pond will be 9 2/3 inches. Wetland species which could be affected are found 50-60 feet beyond that radius of influence at this point. The radius of influence on the northern side of the Class I pond will not cross any wetland boundary until it widens at the northwestern corner. The maximum draw-down at the wet land line near the northwestern corner of the pond would be approximately 15 1/2 inches. Here again the predominant plant species are the upland species of slash pine and gallberry and thus the draw-down will have little effect on those species for reasons mentioned above. On the western edge of the Class III pond is an isolated wetland for purposes of the Water Management District MSSW and Corps jurisdiction only. The edge of that wetland is dominated by slash pine and gallberry. The estimated draw-down on the boundary line of that land in the area dominated by slash pine and gallberry is six inches. There will be no draw-down from that Class III borrow pond area in any wetland dominated by transitional or submerged species. In addition to the above considerations and factual findings concerning the effect of the draw-down, the Applicant is proposing an irrigation systems as delineated above, which will deliver water to the wetlands to mitigate and replenish any minimal impacts of groundwater draw-down. The irrigation system will increase the degree and duration of saturation of the soils at the wetlands' boundary. This will mitigate any minimal effect of draw- down and may actually have the effect of enhancing the health and quality of the wetlands over time, from the wetlands' boundary waterward. In order that the irrigation system will pose the maximum benefit and most closely imitate the natural systems, the irrigation system will be designed for flexible operation. A wetlands ecologist will review the wetlands quarterly and adjust the irrigation system as necessary, as to location and operational regime, in order to properly maintain the health, including water levels and hydro-periods in the wetlands. The Applicant has agreed that the grant of the permit be conditioned to allow for this ongoing quarterly investigation and adjustment. Dr. Motz indicated in his testimony his belief that, to a large extent, the water pumped to the wetlands through the irrigation system would simply immediately migrate to the groundwater and immediately back to the storm water pond, through the effects of the draw-down, and not serve the purpose of replenishing the wetlands. He admitted, however, that he did not know whether the proposed irrigation system would work or not. The Applicant's expert witness in this regard, Dr. Leve, established that the irrigation system would effectively distribute water into the wetlands and saturate the surface due to the "mound effect" of water at the irrigation systems' discharge point at the wetland boundary. He used a standard, generally-accepted "mounding model" to predict the effects of the mounding for the irrigation system. Mounding is a hydrogeological phenomenon whereby water will mound up and create a zone of saturation in the soil at the point of discharge to the ground surface. Mr. Leve ran that model for a cross-section of each of the storm water pumps. He also ran the model for two different values of groundwater inputs into the ponds. A figure of 28,800 gallons of groundwater infiltration into the pond per day, as predicted by the Applicant's expert witnesses, and the 100,000 gallon per day groundwater input predicted by Dr. Motz was used. For both cross- section locations examined by Dr. Leve, the discharge of 28,000 gallons per day at the wetland boundary would raise groundwater levels by approximately three inches. The discharge of 100,000 gallons per day at the same locations through the irrigation system would increase water levels by approximately nine inches. These calculations ware based upon the discharge of the groundwater inputs into the storm water pond only. Discharge additionally of the inputs from storm water runoff from the surface of the landfill into the pond and then through the irrigation system would also be delivered into the wetlands as warranted. Additionally, a berm system will prevent surface water runoff from entering the north dirt borrow area. A berm will be constructed at the eastern boundary of the north borrow area to maintain an interior water elevation of 125 feet or one foot above the natural ground, whichever is higher. Water levels will thus be maintained at the north borrow area so that there will be no lowering or de-watering of the groundwater table. Additionally, storm water will be diverted by berms along the west end of both the Class I and Class III landfills upgradient and into the wetlands, so that the adjoining wetlands receive significant surface water recharge that previously did not flow into those wetlands. Mitigation A mitigation plan was proposed for purposes of both the dredge and fill permit application and, in the solid waste landfill application, for the MSSW permitting. It was incorporated into the draft dredge and fill permit and draft landfill permit incorporated in the Department's Notice of Intent to issue. The mitigation plan and other measures will offset the impacts from filling and other activities caused by the project in both the dredge and fill and MSSW jurisdictional wetlands on the site. The proposed mitigation measures include the creation of 4.76 acres of new wetlands; the irrigation of the wetlands surrounding the Class I and Class III storm water ponds, as delineated above, and the diversion of surface water around the landfills into the wetlands to aid in their recharge. A high quality, forested wetland will be created utilizing the reliable method of mulching and, an extensive hardwood planting program which will include red maple, sweetgum, cypress and tupelo trees. The created wetland will contain deep water and transitional zones. The area will be monitored to insure 80 percent survival of the trees planted and routine maintenance will be performed. Approval of this mitigation plan and any issuance of the permits should include the requirement that rapid replanting be done to replace any dead trees and such approval should also be conditioned on the use of the largest trees possible to be planted, by appropriate tree planting equipment, so that the beneficial uptake and filtering functions, as well as wildlife habitat functions of such hardwood wetlands can begin operating as a mitigatory factor as soon as possible. The created wetland area will replace lost wetlands with a wetland type of higher quality and potentially higher habitat function, depending upon the maturity of the trees planted (see above condition). The wetland replacement ratio attendant to the creation of this wetland area is proposed to be 2.8:1 and the permit should be conditioned on at least that ratio being observed in the mitigation wetland installation plan. Although there was some testimony critical of the wetland creation proposal because it would alter 4.76 acres of uplands which might be of significance to the wildlife in the area, in fact the site of the mitigation area is currently pine plantation which has been greatly altered from its natural state. It does not currently provide high quality upland wildlife habitat. Additionally, only 30-40 percent of the uplands on the entire tract will be altered by the entire project construction proposed. This leaves a majority of the uplands presently on the site in their current condition to the extent that it serves as wildlife habitat at the present time. A conversion of the subject area into a high quality hardwood forest wetland, which would remain bordered by upland on one side in any event, will not have any significant impact on the present value of the mitigation areas as habitat. Wetlands Assessment and Impacts Through the use of consultant personnel skilled in the fields of surveying, biology and botany, the Applicant established jurisdictional lines demarcating the boundaries of DER jurisdiction for dredge and fill permitting purposes and MSSW permitting purposes in the field and adduced evidence of those boundaries at the hearing. The jurisdictional lines established were conservative in the sense that they reflect the jurisdictional standards of the U.S. Army Corps of Engineers, which is generally landward of the lines which would be established by the plant communities characteristic of DER dredge and fill and Water Management District MSSW jurisdiction. The locations of the flags as placed by the biology-botany consultant were then professionally surveyed and plotted by a trained surveyor such that the jurisdictional line was signed and sealed as a "specific purpose of survey." Further, a biologist met with the surveyors weekly to review the plotted line to ensure accuracy. That survey was submitted to the Department in connection with the applications herein. The Department supports that jurisdictional determination in this proceeding. The Department's own jurisdictional determination staff members were on the sites of the jurisdictional determinations for approximately eight days. The location of the wetland jurisdictional line for purposes of MSSW permitting has not been challenged by Petitioners, and no evidence regarding MSSW jurisdiction has been presented by Petitioners in this proceeding. The wetlands jurisdictional survey prepared by the Petitioners, however, showed "new" DER jurisdictional wetlands which would represent, if accepted, an alteration of the DER jurisdictional wetland boundary. Additionally, the challenge to the DER. jurisdictional determination is restricted by the Petitioners to the area around the Class I landfill footprint and its associated storm water pond. No evidence has been presented regarding the jurisdictional determination for the remainder of the site and project, including the access road. Witness Don Garlic has a degree in marine biology with additional coursework and training in the field of botany, including field training in wetland species. He visited the site for seven days for the purpose of critiquing the dredge and fill DER jurisdictional line established by the Applicant and offered as proof by the Applicant in this proceeding. In the 2-3 mile segment of the jurisdictional line around the Class I landfill and associated storm water pond, Mr. Garlick opined that there were three gaps 18-20 feet wide where he did not agree with the dredge and fill jurisdictional line determination. These areas represented by the gaps, if the gaps were determined to be jurisdictional, would add rather long, linear features of putative wetlands to the jurisdictional wetlands already encompassed by the proposed Class I portion of the project. They would add approximately 1/2 acre of additional DER jurisdictional wetlands impacted by the project. The Petitioners, however, did not establish the duration of water flow at any of the areas in which dredge and fill jurisdiction was contested. Mr. Garlick stated that water was flowing each of the seven days he was on the site, from March 28 to May 8, 1991, but stated that it was raining when he was there on April 23. He did not review rainfall data to determine whether it had rained prior to any of his visits. Likewise, he was not shown to have reviewed any groundwater data or to have performed any tests to ascertain groundwater levels in relation to claiming jurisdiction over the disputed Areas A, B, C and D depicted on Petitioners' Exhibit 8. This site has not experienced a prolonged drought. For the period 1988 through the hearing, only the latter portion of 1990 reflected a significant lack of rainfall based on rainfall data obtained from the National Oceanic and Atmospheric Administration Office (NOAA) at the U.S. Navy's nearby Cecil Field, as well as the Jacksonville International Airport. Nineteen eighty-eight, in fact, had above-average rainfall of 61 inches. The Class I landfill area was originally "flagged" in September and early October 1989. July, August and September 1989 were months of above average rainfall. September 1989 had 14 inches of rain, twice the normal rainfall. Nineteen ninety had slightly less than half of its average rainfall for the year, although it started out with normal rainfall and became dry in the fall months. There has since been twice the normal rainfall for the few months of 1991 prior to the hearing. A drought of the type and duration experienced in the latter part of 1990 would have had no significant effect on the plants at the sites in question (sites A, B, C and D). They are perennial plants that remain year-round and therefore are adapted to drought and flood conditions. (T-2047) 1/ The Applicant's jurisdictional determination based upon dominant plant species, established by its consultant in evidence was based upon perennial plant species. Therefore, the hydrological conditions on the site were normal ones when these areas were originally reviewed in 1989 and the jurisdictional delineations established and the conditions found at the site shortly prior to the hearing in March through early May 1991 by Mr. Garlick were unusually wet conditions and do not reflect the normal conditions prevailing at the site. Mr. Byron Peacock was accepted as an expert in wetlands ecology and botany with a B.S. degree in each of those disciplines, with emphasis on Florida wetland species, especially with regard to Florida fresh water wetlands. Mr. Peacock is quite familiar with the site, having been to the site "dozens of times" since September 1989, almost every month for a 21-month period. Mr. Godley, another of Applicant's expert witnesses, also visited the areas put into contention by Mr. Garlick in his testimony for purposes of testifying in rebuttal and also concluded that these areas were not jurisdictional for purposes of the DER's dredge and fill jurisdiction. Mr. Mike Eaton of DER visited at least one of the areas or sites in contention and was of the same opinion. Mr. Garlick had relied on flowing water being present and the plants present to determine that Area A, a ditch along Hells Bay Road, was a jurisdictional wetland area. The areas on both sides are upland. Mr. Garlick testified that there were breaks in the vegetation in Area A and that the vegetation was sufficient to establish a connection. Area A does not contain sufficient water to support a dominance of listed wetland species under either the "a or b tests," as provided in Rule 17-301.400(1)(a) and (b), Florida Administrative Code. There is upland vegetation growing all the way across the ditch on both sides at its connecting point and point of discharge to dredge and fill wetlands. If the ditch held water it would be wettest at this point of discharge into the jurisdictional wetlands, but the ditch does not contain water on a regular and periodic basis, as established by the testimony of Mr. Peacock. Therefore, the water observed in the ditch by Mr. Garlick would have been surface water runoff from the recent high rainfall. Concerning Area B in the Class I storm water pond footprint, Mr. Garlick indicated that he relied on herbaceous wetland plants as a basis for his finding of that as a jurisdictional area. He used the "b test" vegetation method of at least 80 percent transitional plants, less than 10 percent submerged or upland species, as well as the presence of "other indicators" of regular and periodic inundation for that Area B for purposes of the rule cited last above. Area B is a logging road and lies between upland stands of planted pines. It has been used as a road within the past year and there are "rutted- out" or gouged areas in the road caused by vehicular traffic which have puddled water, but between the puddles are areas dominated by upland vegetation. There is also a clear vegetative break in jurisdiction at the point where Area B connects to the jurisdictional line at Area B's southern end. The vegetation at that connecting point is a mixture of red. root, a transitional plant and many upland species, the dominant one being amphicarpum muhlenbergianum, which looks similar to red root in the field. Mr. Garlick testified that red root was the predominant plant in Area B. Mr. Garlick may have mistaken amphicarpum muhlenberqianum for red root. He was not familiar with that upland species and did not know if it was found at the site. A review of photographs from the 1950s, 1960s, 1970s and 1980s showed that Area B had historically always been uplands. The evidence shows that this area holds water only in limited areas following rainfall and that there is no hydrological, "a or b test" vegetative connection between these areas and jurisdictional waters of the State. Area C, located on the west side of the present West Fiftone Road, also contains part of an old road bed, as well as a ditch. Area C was determined to be within MSSW jurisdiction by the Applicant, but was also claimed as a dredge and fill jurisdictional area by Mr. Garlick for the Petitioner. Mr. Garlick indicated in his testimony that plants in Area C were mixed transitional and submerged species, but were sufficient to make out the area as within DER jurisdiction, based upon those plants. He also testified that different parts of Area C met the "a test" or the "b test." The ditch on the eastern side of Area C is dominated by upland vegetation, including amphicarpum grass, slash pine and goldenrod. The slash pines growing in the ditch, as shown by a photograph in evidence, were several years old. This ditch was dry on all of Mr. Peacock's visits to the site except recently during heavy rains. The remainder of Area C is characterized by a canopy of slash pines, a subcanopy of titi shrub of an upland type, with less than ten percent of the vegetation being characterized by bay and tupelos. There is a ground cover over most of that area consisting of upland species such as chokeberry, gallberry and reindeer moss. This area was determined to be jurisdictional for MSSW purposes because of a wet area in the middle containing fetter bush and sweet gallberry, which are both transitional species for jurisdictional purposes. The entire Area C was delineated as MSSW in the permit application, even though it may not all be jurisdictional, simply for ease of delineation and survey. The MSSW wetland areas within Area C, however, have no vegetative or hydrologic connection to the dredge and fill jurisdictional wetlands. Area C thus does not contain sufficient water or vegetation under either the A or B test connected with other jurisdictional areas to be considered jurisdictional for purposes of the DER's dredge and fill jurisdiction. Area D consists of a rutted trail-road used on a regular basis by persons visiting the tract. There is an upland pine plantation on either side of the roadway. Mr. Garlick contended there was a "flow way" in Area D, but that the vegetation was spotty or sporadic. During the past 21 months, Area D was dry every time Mr. Peacock was on the site, except recently after prolonged, heavy rains. At the eastern end of Area D near its connection to Area C, there is a patch of upland amphicarpum grass, growing all the way across the ditch and road. There is also the presence of beak rush, an upland plant which looks similar to submerged rush. There is insufficient water or wetland vegetation under either the a or b test to establish that this Area D is jurisdictional. The evidence thus did not support the Petitioner's contention that additional dredge and fill wetlands would be impacted by the project. The areas claimed by the Petitioners as additional jurisdictional wetlands did not contain sufficient water to be determined jurisdictional, pursuant to DER Rule 17-301, Florida Administrative Code. These areas held water only at certain times of the year in direct response to heavy or frequent rainfall and were normally influenced, that is, fed, by surface water rather than groundwater. Likewise, these areas did not contain sufficient plant species in the canopy, subcanopy or ground cover to be considered jurisdictional pursuant to vegetation indices and procedures delineated in Rule 17- 301.400(1)(a) or (b), Florida Administrative Code. Mr. Mike Eaton of DER testified and established a 1990 DER policy embodied in a memorandum admitted into evidence explaining how the Department employs the above-cited rule for purposes of using hydric soils in making dredge and fill jurisdictional determinations. Both Mr. Eaton and the DER policy in evidence established that hydric soils are not used by the Department except as an indicator of regular and periodic inundation once "b test" vegetation has been determined to be present for purposes of the above rule. Mr. Garlick testified that he used hydric soils as a "back up" to jurisdictional determinations based upon hydrology and plants. He did not identify any area where his jurisdictional determination was based on soils alone. The Department policy memorandum in evidence emphasizes the importance, in jurisdictional determinations with hydric soils as an aid, of not merely determining whether the soil in question is hydric, but also of investigating the specific characteristics of the soil profile, which the Department maintains must be performed by a soils scientist. Mr. Carlisle, a soil scientist, visited the site and took samples of the areas indicated by Mr. Garlick. These locations were located in an approximate fashion by Mr. Garlick on Petitioner's Exhibit 8 at the hearing. Thirty-four of the 35 samples taken were determined to be hydiric by Dr. Carlisle. There are, however, breaks of up to approximately 525 feet between the hydric soils test findings in Areas A, B and D and yet the distance between one hydric and non-hydric soil test finding was shown to be approximately 50 feet. No soil samples were taken by Dr. Carlisle in Area C. These samples are found to provide an insufficient basis for determining the presence of hydric soils throughout Areas A-D. Additionally, Areas A-D did not contain areas of "b test" vegetation contiguous to other jurisdictional areas. Therefore, even if hydric soils had been present throughout these areas, these soils standing alone, without supporting "b test" vegetation, are insufficient to establish jurisdiction in the areas maintained to be so by Mr. Garlick. General Wetland Impacts This project will impact wetlands subject to the DER jurisdiction and which are jurisdictional for MSSW purposes under Chapter 40C-4, Florida Administrative Code, the rules of the St. Johns River Water Management District. Thus, a dredge and fill permit is required pursuant to Section 403.91 et seq., Florida Statutes, and DER Rule 17-312, Florida Administrative Code. Areas subject to DER dredge and fill jurisdiction and MSSW permitting jurisdiction are considered pursuant to DER Rules 17- 301 and 40C-4, Florida Administrative Code. The 1,288 acre site contains approximately 550 acres of wetland, much of which contains planted pines as well as some naturally occurring pines, as well as hardwood swamp, cypress and gum swamp, seepage slope, ditches and swales. Virtually all of the wetlands have been adversely affected in some way by the forestry practices which have occurred and are still occurring on the site. Most of the sloughs and natural flow-ways have been channelized. Ditching has drained the adjacent wetlands and significantly altered the hydrology of the entire wetland system on the site. The wetland known as Hells Bay Swamp, immediately east of the landfills, is currently being clear cut by the Gilman Paper Company. The 550 acres of wetlands are jurisdictional for either dredge and fill or MSSW purposes or both. Some 3.17 acres of MSSW wetlands will be impacted by project construction; 1.61 acres of these are also dredge and fill wetlands. The 1.61 acres of the impacted dredge and fill and MSSW wetlands consist of roadside ditches along the Hells Bay Road and a road on the north side of the Class I landfill. These roads are currently subject to logging traffic, which decreases the usage of the roadways and ditches by wildlife. Consequently, the master of species present and using these ditches is limited. In addition to the 1.61 acres of ditches, the impacted MSSW wetlands also include 0.16 acres of wetland ditches along the entrance road in proximity to dredge and fill wetlands, a 0.80 acre isolated cypress head wetland located within the footprint of the Class I landfill and a 0.60 acre wetland located along West Fiftone Road extending into the south border of the Class I landfill footprint. The 0.80 acre cypress head has already been impacted by a logging road or fire break, and ditches have been constructed through the interior of it. The larger cypresses have been logged, and the remaining vegetation is sparse, rendering it of little quality as habitat for fish and wildlife. The 0.60 acre wetland extending into the south border of the Class I landfill is an old road bed with evidence of ruts from vehicular traffic depicted on photographs in evidence. This area has a slash pine canopy and is dominated by titi shrubs, with a few black gum and traditional wetland plant species such as fetter bush and gallberry in disconnected areas. It is a low quality wetland of scant value as habitat for fish or wildlife. Prior to and during construction, as a condition on a grant of the permits, all wetlands on the site will be protected from erosion, siltation, scouring or excessive deposition of turbidity, de-watering or other construction and operationally-related impacts by the installation and use of siltation barriers placed at wetland boundaries. Because of the significant possibility of the impacts mentioned above, especially siltation and turbidity, to the wetlands during the construction phase of the facilities and attendant to ultimate operation of the landfill itself, grant of the permit should be conditioned on acceptance of monthly inspections by DER enforcement personnel once construction has begun. Wildlife and Archaeological Resource Impacts Wildlife surveys were conducted by expert witness Isaac Rhodes Robinson and members of his staff, as well as by Biological Research Associates, Inc. in the months preceding the hearing. Mr. Robinson and the biologists on his staff spent approximately 1,000 man hours surveying the site, and Mr. Robinson, accepted as an expert in wildlife ecology and wetland ecology, testified on behalf of the Applicant in this proceeding. Assessments of the site were performed by reviewing relevant literature as well as conducting field surveys for both upland and wetland species. No evidence was found of any threatened or endangered species on the site. Mr. Robinson and his staff conducted surveys in 1990 and in early 1991 and biologists from Mr. Robinson's staff were present on the site at various times from September 1989 through the time of the hearing. Surveys performed by Mr. Robinson and his personnel were conducted in accordance with Florida Game and Fresh Water Fish Commission (FGFWFC) guidelines and exceeded that agency's guidelines by surveying 100 percent of the upland areas. No testimony of any witness in this proceeding indicated any physical evidence of use of the site by any endangered or threatened species. Wildlife surveys revealed a shall colony of gopher tortoises, listed as a species of special concern by the FGFWFC in a marginal habitat zone on the extreme western boundary of the Class I disposal area. The colony consists of less than ten individuals and there will not be a significant impact to the tortoises because the individuals will be trapped and relocated to a more suitable habitat on another area of he Applicant's tract, which will be undisturbed by the landfill or its operations, or else to a suitable habitat area off-site, as directed by the FGFWFC. Jay Stephen Godley was accepted as an expert in wildlife ecology and wetlands ecology. He directed an independent assessment of the site and project's impacts. The assessment included reviewing permitting documents, aerial photographs and literature pertaining to wildlife use of the site, as well as over 90 man hours spent at the site. He confirmed that the small population of gopher tortoises was the only significant species on the site and that the project would not significantly impact any listed wildlife species. Extensive trapping and investigation of gopher tortoise and armadillo burrows reveal no evidence of listed "commensal" species, or those species commonly found in association with gopher tortoises, such as Florida mice, gopher frogs, Florida pine snakes, or Eastern indigo snakes. In additions the isolated cypress head in the Class I landfill footprint was sampled for gopher frog tadpoles, and none were found. Florida pine snakes prefer scrub or sand hill habitats, neither of which are found on the site. Pine flatwoods environments, without the presence of either sand hill or scrub habitat, like this site, are not good indigo snake habitat. No indigo snakes' shed skins or other evidence of indigo snake frequency were observed on the site. Indigo snakes are large black snakes which are active during daylight hours and easy to observe in the course of extensive surveys such as those that were conducted for purposes of this project. Considering the amount of time spent by the various biologists on the site, it is quite likely that indigo snakes would have been observed if they frequented this site. The project will have no significant impact on wading birds. All wetlands were surveyed for listed bird species for a minimum of five days using FGFWFC guidelines. No wading birds were observed on the site during the 21 month period of review by Mr. Robinson's firm. The existence of the wood stork, bald eagle or Florida sand hill crane was not established on this site and is considered unlikely by the expert witnesses, whose opinions are accepted. No eagle nests were observed and, since the tree cover provides very limited extent of open water, the site is less than satisfactory as habitat for the little blue heron, snowy egret and Louisiana heron. The only wading bird observed by the Petitioner's expert witness on wildlife issues was a little blue heron observed in a wetland area east of the site, which is off the site being purchased by the Applicant and which was recently clear-cut by the Gilman Paper Company. The project will have no significant adverse impact on the Florida black bear's habitat. The black bear is a threatened species, but black bears do not use the site. No evidence was presented that black bears have ever been present on or in the immediate vicinity of the site. No witness, including Mr. Goodowns, an employee of Gilman Paper Company who has frequently visited and worked on this site over many years, has ever observed a black bear or any sign of a black bear present on the site. Bee hives have been kept at the site since at least 1969 and, although these are very attractive to black bears, they have never been known to have disturbed the hives, nor has it ever been necessary for bee keepers to erect electric fences or other devices to protect the hives from bears. The site presently is not far isolated from human activity, which fact deters the use of it as a habitat or an occasional travel way for black bears. It is located in an area completely enclosed by I-10, State Roads 228 and U.S. Highway 301, all heavily traveled public highways, as well as in close proximity to the town of Maxville, approximately two miles away, and Macclenny, approximately five miles away. Highways with high traffic volumes are significant barriers to movements of black bears, rendering it even less likely that black bears have or will frequent the site. The only evidence of potential black bear presence anywhere near the site presented by the Petitioners was the site's position near the Osceola Black Bear Range, as interpreted from one published article, as well as indication of three bear road kills from six to 15 miles away from the site, and supposed black bear movements recorded by the FGFWFC, all represented on a hand-drawn map, only admitted a corroborative hearsay pursuant to Section 120.58, Florida Statutes. The map exhibit contained the expert's own redrawing of his interpretation of the extent of the Osceola Black Bear Range from the article he referenced, which itself was not offered into evidence. Bear movements depicted on the map really consisted of those of a bear apprehended by the FGFWF and released in the area. The map did not show any roads, therefore making location and distances to the reported road kills speculative at best. Because black bears do not use this site and because of its encirclement by significant human activity, the site is not significant as a bear dispersal corridor or travelway between the Osceola Forest bear population and the Ocala Forest population. No direct evidence by radio-telemetry data or otherwise was offered to show that black bears actually move between the Osceola and Ocala Forest populations, nor particularly that they move through the area in the immediate vicinity of the project site. Construction of the landfill would not prevent the movement or foraging of black bears through the site. Neither fencing nor presence of traffic on the landfill access roads only during daylight hours would prevent such movement. It is also unlikely that bears would likely be hit by traffic on the roads because the noisy trucks which will use the road would provide ample warning to bear's of any danger from traffic so they would avoid it. If the landfill were constructed on this site, less than one-half of 5/100 of one percent of the 3,800 square- mile area of the Osceola Black Bear Range, referenced by the Petitioners' expert witness, would be impacted. The site itself does not provide high quality black bear' foraging or denning habitat. Even the Petitioners' expert characterized it as "good" or "better than average" habitat. All but 3.17 acres of the area to be impacted by the project is upland, consisting primarily of pine flatwoods. Authoritative studies show that flatwoods are not heavily utilized by bears, which spend 70 percent of their time in swamp or wetland habitat. The 550 acres of wetlands, including approximately 280 acres of swamps, which will be left undisturbed on the site, will provide habitat and travel corridors for the black bears should any ever frequent the site. Additionally, the 4.76 acres of hardwood wetlands to be created as mitigation, would add high quality wetland habitat for black bears. Therefore, due to the extremely small area involved, the unlikelihood of use by black bears and the mitigation proposed, the landfill will have virtually no impact on black bear habitat, travelways or populations. The evidence thus established that the project will not have an adverse impact on endangered or threatened species or their habitats. Because the site has been under extensive commercial forest management and harvest operations for over forty years, the density of plant and animal life has been reduced, thus making the site as a whole, low quality wildlife habitat.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the Department of Environmental Regulation approving Trail Ridge Landfill, Inc.'s applications for the above-referenced permits for the proposed solid waste management facility, including a solid waste management facility permit, a storm water/management and storage of surface waters permit and a dredge and fill permit, provided those mandatory conditions specified in the Notices of Intent to issue such permits, as well as those conditions found to be necessary in the above Findings of Fact and Conclusions of Law are made mandatory conditions of permitting and subsequent facility operations. DONE AND ENTERED this 20th day of September, 1991, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 20th day of September 1991.
The Issue The issue is whether Petitioners are entitled to an after-the-fact permit from Respondent for the garage and storage building erected by Petitioners within the floodway of the Suwannee River.
Findings Of Fact Petitioners are the owners of real property located at Lot 15, Suwannee Bluffs as per Plat Book 4, page 18 of the public records of Lafayette County, Florida. Respondent, Suwannee River Water Management District, is an agency of the State of Florida with a responsibility for surface water management within the District. Petitioners live in a home on their Suwannee River property and, in 1999, completed a garage and storage structure on the property without obtaining a permit for construction of the structure. The structure measures 35 feet by 50 feet. It is a concrete block structure on a concrete slab with a metal roof. There are three doors on one side of the structure. The remainder of the structure is enclosed. On or about March 31, 1999, Petitioners, prior to construction of the garage and storage structure, applied for an environmental resource permit for a boat ramp, which permit was subsequently granted. The entire lot of Petitioners is within the floodway of the Suwannee River. The floodway is defined as a work of Respondent's district in Rule 40B-4.3000, Florida Administrative Code. The Suwannee River flows within the boundaries of the Suwannee River Management District. On or about April 18, 2000, Notice of Violation was sent to Petitioners by Respondent. On or about June 19, 2000, Petitioners executed a Notice of Intention to construct a surface water management system for the already completed garage structure. Basically, the surface water management system envisioned by Petitioners would have consisted of modifications to the already completed garage to permit flood waters to flow through the structure. Respondent did not send any responsive formal notice of denial to Petitioners regarding such proposed intention. Instead, Respondent filed a lawsuit in July of 2000, within the 90-day period required by Section 120.60(1), Florida Statutes, in circuit court against Petitioners to prevent the construction of the system. Such action by Respondent constituted denial of Petitioners' requested action. Petitioners' garage construction was in violation of Ordinance 1-87 of Lafayette County, Florida, and in fact, Petitioners received a Notice of Violation from Lafayette County, Florida, dated December 9, 1999, which has still not been resolved. Rule 40B-4.3040, Florida Administrative Code, prohibits the placing of a structure in the works of a District without a works of the District development permit. Petitioners' garage structure was not permitted and was in violation of the rules of the District in force and effect at the time of its construction, notwithstanding Respondent's informal delegation of enforcement of those rules to local county governments in Respondent's district prior to July 1999. Rule 40B-4.3030 Florida Administrative Code, proscribes the issuance of a works of the District's development permit for any work structures, road, or other facilities which have the potential of individually or cumulatively reducing floodway conveyance or increasing water surface elevations above the 100-year flood elevation or increasing soil erosion. Testimony of two experts offered by Respondent at the final hearing establishes that the structure in question will cumulatively reduce floodway conveyance and increase water surface elevations above the 100 year flood elevations and potentially increase soil erosion. Adverse impacts to the public interest include the following: increased flood levels; increased scouring by debris and erosion; and increased water surface elevations above the 100 year flood elevation. The cumulative impact of allowing Petitioners' structure and other structures would magnify the problems of increased erosion, debris damage, and floodway conveyance. The cumulative impact from such construction along the water could have significant cumulative adverse impact on the waters of the State of Florida and specifically, the Suwannee River.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Suwannee River Water Management District enter a Final Order dismissing the petition in this case and denying the issuance of an after-the-fact works of the District permit to Petitioners.

The Issue The issue in this case is whether the development order issued by Polk County for Robert Crowder's development known as Paradise Country Estates complies with Chapter 380, Fla. Stat. (1991). The Department of Community Affairs' Petition for Appeal of Development Order (the DCA Petition) alleges that the development order is contrary to Polk County's 1985 comprehensive plan for the following reasons: Paragraph 11 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 9, Objective III, "Natural Resources," of the Land Use Element (LUE) of the 1985 Plan. Policy 9 states: "Structures should be placed in a manner which will not adversely affect the natural flow regime and which will not reduce the recharge capabilities." Paragraph 12 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 10, Objective III, "Natural Resources," of the LUE. Policy 10 states: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Paragraph 13 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 11, Objective III, "Natural Resources," of the LUE and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Respectively, these policies state: 11. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Paragraph 14 of the DCA Petition alleges that the development order is contrary to a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources," which describes the Green Swamp as a "rare and unique land area resource for conservation consideration" and also states: The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Paragraph 15 of the DCA Petition alleges that the development order is contrary to the following section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships": The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. Paragraph 16 of the DCA Petition alleges that the development order is contrary to Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan: "Protect or improve existing ground and surface-water quality." Paragraph 17 of the DCA Petition alleges that the development order is contrary to Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE: Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. Paragraph 19 1/ of the DCA Petition alleges that the development order is contrary to Policy 2, Objective IV, "Residential Uses," in Part V of the LUE: Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. Paragraph 20 of the DCA Petition alleges that the development order is contrary to Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code). 2/ Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Paragraph 21 of the DCA Petition alleges that the development order is contrary to Section 5-2(4) of Polk County Ordinance 81-28. 3/ Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Paragraph 22 of the DCA Petition alleges that the development order is contrary to Section 6-2(3)(a) of Polk County Ordinance 81-28. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site.
Findings Of Fact The Proposed Project and Location. The project site is on Dean Still Road in Polk County, approximately 2 miles west of State Road 33. It is approximately 6 and 1/2 miles from Polk City and 15 miles from the City of Lakeland. The proposed project is comprised of 356 lots on approximately 1280 acres with a gross density of 1 unit per 3.6 acres. Although the average lot size varies, the project was reviewed under the Southwest Florida Water Management District's (SWFWMD) criteria for rural development which requires that at least 90% of the lots be at least 2 acres in size (excluding jurisdictional wetlands), and 10% of the lots be at least 1 acre (excluding jurisdictional wetlands). The site has been zoned Rural Conservation under Polk County's Zoning Code for approximately 12 years. This designation allows a density up to 1 unit per acre. Individual water wells and on-site waste disposal systems (septic tanks) will be utilized for each home. There are no water or sewer extensions proposed for the site or for adjacent areas by any governmental entity. Access to the site from Polk City is along Dean Still Road, which is unpaved at this time. The County has plans to pave it in the near future. Of the 1280 acres comprising the project site, 362 acres have been claimed as jurisdictional wetlands and approximately 642 acres have been mapped within the 100-year floodplain by the Federal Emergency Management Agency (FEMA). 51 of the lots platted in the project are entirely within the FEMA 100- year flood plain. Several other lots contain large portions within FEMA 100- year flood plain. Despite the significant amount of wetlands and floodplains on the site, the project is designed so that no net loss will occur in the floodplains and less than 1% (.59%) of the jurisdictional wetlands will be impacted by development. Impervious conditions on the site will only increase by 2.8% after development. All structures will be set at or above the 100 year flood elevation, as calculated by the project engineers, and will be constructed in accordance with the County's flood protection standards. The project is designed so that post-development runoff is less than pre-development runoff and post-development drainage basins conform to pre-development drainage basins. Existing drainage patterns for the site are designed to be maintained. The property comprising the project has been used through the years for a variety agricultural purposes, including harvesting watermelons, soybeans, corn, and silage. It has been drained and ditched to facilitate these activities. It is currently being used for grazing cattle. A sod farm is located to the south of the property. Additional cattle grazing lands run south from there to Polk City. To the north of the site are ranchlands which run to the border of the Withlacoochee Wildlife Area. Immediately to the west of the site are 20-30 scattered mobile homes and additional ranchlands in a subdivision known as Evans Acres. This subdivision was initially approved by DCA in 1983, and was comprised of 48 lots on approximately 1,290 acres. The original lots ranged in size from 5 to 60 acres. Apparently, individuals have since split their lots and many of the existing lots are 2 to 5 acres in size. A few of the original lots are used for both residential and ranching purposes. Including the large and small lots, there are approximately 163 lots on the property comprising Evans Acres. On the property directly to the east of the site are approximately 16 mobile homes along Melody Lane. These existing homesite numbers are small and scattered when compared to the 356 lots proposed for Paradise Country Estates. Approximately 120 families live in the general vicinity of the proposed project. The Green Swamp. The project is within the Green Swamp Area of Critical State Concern (ACSC). The site is within the drainage basin of the Withlacoochee River, which has been designated an Outstanding Florida Water (OFW) and is approximately three and a half miles to the north. The Green Swamp ACSC was designated by the Legislature. Chapter 79- 73, 380.0551, Florida Statutes (1991). It was the second area to be designated and now is one of only four areas in the State retaining this designation. The Green Swamp was designated because the area's natural resources were considered to be of regional and statewide importance and because of concerns that uncoordinated development could endanger these resources. The Green Swamp is a regionally significant area for recharge of the Floridan Aquifer. The Green Swamp is unique because the top of the Floridan Aquifer is at or near the surface over much of the area. This creates what is known as the potentiometric high of the Floridan Aquifer. The potentiometric high pressurizes the Floridan Aquifer, permitting it to be used for drinking water wells. The Florida Aquifer serves as the principal source of drinking water for central Florida. It supplies the entire State with about 48 percent of its ground water supply. The potentiometric high also serves to hold back salt water intrusion into the Floridan. Recharge is important in maintaining the potentiometric high of the Floridan Aquifer. Although the Green Swamp has been characterized as a recharge area for the Floridan Aquifer, the actual recharge capabilities of the Green Swamp vary considerably throughout the region. Some areas within the Green Swamp, such as the high, dry, sandy ridge on the eastern boundary of the Green Swamp clearly are high recharge areas. In some areas, the Floridan Aquifer rises essentially to the ground surface, with no confining layer above it. In those areas, a considerable amount of surface water filters into the Floridan Aquifer. In other areas, including in the vicinity of the project site, recharge capability is considerably less. See "G. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code, (3) Ground Water Recharge." The head waters of several rivers, including the Withlacoochee River, are in the Green Swamp. Polk County's Comprehensive Plan. Polk County's Comprehensive Plan, as amended by Polk County Ordinance 85-08 (Ordinance 85-08), is referred to as Polk County's 1985 comprehensive plan, or the 1985 plan. It includes a Land Use Element (LUE) and a Conservation Element. The Land Use Element. The 1985 Plan is a "policy plan." As a "policy plan," the LUE does not map land use classifications or densities or intensities of development. The different parts of the plan must be considered together to ascertain their meaning. As stated in the Foreward to the LUE: The Policy Plan is a flexible and realistic guide to future public decisions. Existing conditions are first determined and analyzed. Then, community goals are identified providing a process of finding out where we are and where we want to go. * * * . . .. The challenge is to determine the means of achieving the identified community goals at minimal cost and the least possible hardship on any segment of our society. Under the policies planning process this is accomplished by developing all possible alternative courses of action that will advance the community toward the desire goal. The policies are then a general statement of purpose and outlining broad principles toward which the plan is guided in the implementation stage. A policy plan does not detail specific actions or locations on a map. Rather it provides a broad framework within which day-to-day decisions are made in a consistent manner toward an identified goal. The ultimate product of those community goals will be the heritage of Polk County's future. At 4-2, the LUE discusses the need to give attention to "the proper distribution of population densities in keeping with sound planning practices, the physical capabilities of the land, and the relationship of the population and housing densities to existing or proposed transportation facilities and other community services." It then speaks to "Retention of Open Spaces": A second potential problem to be faced, as urban growth continues, is the potential loss of the open space characteristics that now contribute substantially to its desirability as a community in which to live and visit. To a large extent, the desirable characteristics are provided by extensive agricultural areas. Such uses are compatible with residential and other types of urban land uses and should be encouraged to remain to the maximum extent possible. Desirable open space is also presently provided by . . . wetland areas not suited for urban development. By encouraging such areas to remain in their present condition, a substantial amount of open space can be retained to provide the needed visual relief and openness necessary within a highly urbanized community. At 4-5, discussing "Retention of Unique Agricultural Lands," the LUE states that cattle raising and field crops are subject to potential intrusion by urban development and states: "The development of planning techniques, which will encourage the retention of important agricultural lands and provide for orderly urban development, thus becomes a matter of considerable importance." The Goals, Objectives, and Policies (GOPs) of the LUE starting at 5-1 include the following: General Goal: To maintain productive and mutually compatible use of lands and waters within Polk County in a manner consistent with the economic, physical and social needs, capabilities, and desires of Polk County and its citizens. Objective I - Agricultural Uses: To ensure that a sufficient quantity of appropriate lands are available and protected for productive agricultural uses necessary to a sound economic base. Policies: * * * 2. Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. * * * 5. Provide all possible incentives for the retention of lands into agricultural production. * * * Objective III - Natural Resources Minimize adverse impacts of development on valuable natural resources including the protection of water quality and quantity in surface and ground waters. Policies: * * * 2. The subdivision and platting of land shall be permitted in accordance with the zoning district applied to the property and in compliance with the Polk County Subdivision Regulations and Flood Protection/Surface Water Management Ordinance. * * * Site alteration should be permitted only when such alteration will not adversely affect the natural flow regime or the natural recharge capabilities of the site. Site alteration should be permitted only when such alteration will not result in the siltation of wetlands or reduce the natural retention and filtering capabilities of wetlands. Site alteration activities should provide for water retention and settling facilities; should maintain an overall site runoff equivalent to the natural flow regime prior to alteration and should maintain a runoff rate which does not cause erosion. * * * Storm water runoff should be released into the wetlands in a manner approximating the natural flow regime. Structures should be placed in a manner which will not adversely affect the natural flow regime and which well not reduce the recharge capabilities. Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. Objective IV - Residential Areas To ensure that an adequate supply of appropriately located lands are available for the development and maintenance of residential areas that can be efficiently and effectively provided with necessary public facilities and services. Policies: Promote and encourage the provision of a wide range of housing opportunities, in appropriate locations, to permit a choice of housing types to suit the particular needs of all citizens. Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. * * * Encourage new residential development that can be effectively served by the existing transportation facilities. Promote new residential development in non-urban areas, that is properly designed to combine with future adjacent development, to create a neighborhood of sufficient size to facilitate the efficient and effective provision of all necessary public facilities and services. Part VI of the LUE, entitled "Alternate Approaches," discusses the pros and cons of different concepts for planning and managing of growth. It settles on a "Resource-Responsive Concept" as the preferred growth alternative. This concept holds in part: Wherever possible, future growth should be encouraged to take place in or near established urbanized areas. Scattered growth incapable of functioning as meaningful self-contained communities should be discouraged. And it is preferable that the urbanizing area, as it extends over extensive areas within the County, not be developed in one continuous, monotonous maze of residential, commercial, and industrial uses - but that there be open space provided at appropriate intervals so as to provide visual relief and a sense of scale to the overall urban community. Such open space areas can be productively utilized for agricultural and conservation purposes or recreation areas, public facilities and services required. It is proposed that the most appropriate urban growth concept to meet such guide-lines and the policy statements of this land use plan be a resource-responsive growth concept. Under this concept, urban growth and development will be guided and encouraged with respect to its responsiveness to the natural and human resource capabilities of the County. Within any given area of the County, the resources will be careful evaluated in terms of their capability to support growth, and the physical form and intensity of development will be then shaped to provide the physical form and intensity of development will be then shaped to provide a balance with such resources. Prime resources to be considered are as follows: Natural Resources Topography and soil conditions Vegetation and tree cover Wildlife habitats present Drainage characteristics; relationship to rivers and lakes Natural water supply capabilities General aesthetic qualities Human Resources Transportation facilities (roads, railroads, airports) Available water supply and sewage facilities Community facilities, such as schools, parks, libraries Protective services, such as fire and police Established land uses within the area Economic conditions and potentials. Part VII of the LUE, entitled "Implementation," states: "Initial implementation of a Comprehensive Plan and initiation of the continuing planning process for growth management requires the establishment of principals and standards for measurement of proposed activities against the adopted policies of the community." It includes a section entitled "Principles and Standards for the Control and Distribution of Population Densities and Structural/Development Intensity," which provides in part: All Types of Urban Development: * * * Each new development or land use should follow sound land planning principles to maximize site advantages, avoiding when possible, adverse impacts on the natural resources and hazards to health, safety, or general welfare. * * * Residential Development: Low-density single-family development (1-4 units/acre), other than rural residences related to agricultural operations, shall be located in areas capable of being developed into stable, cohesive neighborhoods. In a section entitled "Legal Requirements of Implementation," it states that "all actions taken by local government, whether in the form of permitting private development to occur or in the provision of public facilities and services, are required to be fully consistent with the adopted Comprehensive Plan. The plan, once adopted, must occupy a central position in the consideration of all proposed development." In another section, entitled "Coordination with Other Plan Elements," it states that the "land use element cannot be implemented alone [but] must be coordinated with the [other elements]." In another section, entitled "Needed Improvements in the Zoning Ordinance," it is recognized that "it will be essential that a thorough review of the zoning ordinance be undertaken and that the ordinance be revised as appropriate to achieve consistency with overall planning objectives." It acknowledges that there were "major identified deficiencies in the current zoning regulations" and advises that "the following needs among others should be addressed as a minimum in making revisions to the zoning ordinance": "Revision of the Density Requirement in Residential Districts." Despite the admonitions in the 1985 Plan, to date there has been no revision of the land use classifications, densities, or intensities in the County's zoning code. As before the 1985 Plan was adopted, zoning in the Green Swamp ACSC remains Rural Conservation (RC) and allows up to one unit per acre residential development. The Conservation Element. Part II of the Conservation Element of the Polk County Comprehensive Plan is a "Summary of Natural Resources." At 2-18, there appears a section entitled "Rare and Unique Natural Resources," which describes the Green Swamp, as well as other natural resources in the County, as a "rare and unique land area resource for conservation consideration." At 2-19, as amended by Ordinance 85-08, this element of the comprehensive plan also states: This area comprises the hydrologic heartland of Central Florida and contains the headwaters of the Withlacoochee, Hillsborough, Peace and Oklawaha Rivers. The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Part IV of the Conservation Element is a "Summary of Special Problems, Areas, Issues, and Relationships." Starting at 4-2, it addresses the following: Displacement . . .. Cities in Polk County have historically developed on the ridges and the urbanized areas are spreading outward rapidly into the prime citrus lands and the "marginal" (flood prone) lands. There is considerable concern about urban development in wetland soils and flood prone areas. The double barreled concern for development in wetland soils and wetland areas is that they might well serve valuable natural functions and the private and public problems created by development subjected to flood damages. This property damage promotes public pressure for drainage in wet areas. The issue in wetland drainage and flood control is the jeopardy of natural functions that wetlands and water fluctuations provide in natural systems and flood damage costs. . . . [C]oncern for the growing demand for uplands development which steadily displaces [good pasture land] . . . relate[s] to the use of good pasture land for development. Density The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. * * * Water * * * Another area of concern relates to the draw down and recha[r]ge of the Floridan Aquifer and is claimed to be a rational concern of an area much larger than Polk County. * * * Pollution Environmental pollution, as it relates to water, is a major local concern. * * * Water pollution is concerned because of its effects on recreation and tourism. Water degradation and the pollution of lakes and rivers tends to remove the intangible value that Polk County enjoys in thee form of its surface water resources. * * * Also, the related cost issues of municipal sewage treatment and disposal, effluent disposal techniques, septic tank useage are environmentally economic choices to be made by the public. Discussing the topic, "Preservation and Management," starting at 4-4, Part IV of the Conservation Element states in part: Many issues relate to what, how, or when something should be conserved. * * * Lakes, rivers and canals of the county are of concern as sources of flooding and as resources for flood control, if properly managed. Flood prone areas surrounding surface water have been identified for much of the county. These water bodies are also legitimate concerns as the habitat for fish and other wildlife that provide a significant value in their own right. The area of these water bodies are also special scenic and recreational values that contribute to tourism and development. Part V of the Conservation Element is where the "Goals, Objectives and Policies" are found. It start with some general observations, including in part: . . .. It can be expected, therefore, that the natural environment of the county will continue to undergo modification of one type or another in response to the needs of people. . . . The inventory of total space will, therefore, diminish as these changes take place, resulting in corresponding losses within particular categories of natural resources. What is important is that no critical loss of impairment of a natural resource take place; that development be managed so as to create minimum disturbance of the remaining natural resource systems; and that there be compensation replenishments of resources wherever possible. It then lists a General Goal and several resource-specific objectives and policies: General Goal: Maintain, protect, develop and utilized the natural resources in a manner that will balance and replenish the natural ecological systems and will best serve and promote the desired quality of life for Polk County resident, present and future. * * * Water Resource Objective: To conserve and protect the quality and quantity of water resources through proper management. * * * 6. Identify and protect significant acquifer [sic] recharge areas for maximum recharge capability and protect the water available for aquifer recharge. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Protect the functions of the Potentiometric High of the Floridan Aquifer. Prevent further salt-water intrusion into the Floridan Aquifer. Protect or improve existing ground and surface-water quality. Protect the water retention and biological-filtering capabilities of wetlands. Protect the natural flow regime of drainage basins. Rare and Unique Natural Resource Objective: To conserve and protect, through proper resources management, areas having unique natural characteristics and particularly sensitive environmental balance. * * * Policies: Identify all significant areas in Polk County deemed to have unique natural resource characteristics. Encourage proper management of unique wetland areas of the County as a vital water resource. Encourage a proper system for control of development in flood prone and wetland areas to regulate alternation [sic] of the natural system of water retention and storage during periods of heavy rainfall. Preserve and protect, to the maximum extent possible, all delineated areas having valuable unique resource characteristics. Part V of the Conservation Element concludes with a "Summary," which states in part: The objectives and policies set forth above should not be considered as controls to be rigidly applied in every instance of decision-making dealing with the natural environment. Rather, in dealing with resource conservation issues, guidance is preferable to control. . . . A number of potential implementation actions and programs, presented in the following part, will further assist in establishing the direction and scope of conservation activities in the County. Part VI of the Conservation Element is entitled "Implementation." While acknowledging at 6-1 that Polk County cannot establish an implementation program unilaterally, without regard to the co-responsibilities of other governmental authorities at the regional state and federal levels, it states at 6-2 that Polk County "can and should": Utilize the general objectives and policies established by this Element as considerations in all decision making concerning the use and improvement of land within the County. * * * 3. Utilize, to the fullest extent possible, the policies and implementation controls of other elements of the Polk County Comprehensive Plan, and those of other governmental entities having jurisdiction, to further the conservation of natural resources. Starting at 6-3, Part VI discusses the Conservation Element's "Relationship to Other Plans." At 6-4, after stating that the Conservation Element will be largely implemented through the policies and programs of other comprehensive plan elements, Part VI provides: Land Use Element - This element will provide the overall framework for conservation [sic] potentialities through the manner in which land uses are distributed, arranged, and interrelated throughout Polk County. Policies and implementation programs of this element will determine the degree to which new development is properly related to soil types and capabilities, natural habitats, flood prone areas, wetlands and unique resource areas of the County. Land regulatory controls such as zoning, subdivision regulations and development impact reviews provide the basic tools for implementation of the policies of the Land Use Element. Starting at 6-5, Part VI discusses "Guidelines for Implementation." At 6-5, it points out: The nature of conservation policy, being of such broad application and diversity of interest, requires that its effective implementation utilize many approaches, techniques and procedures. Its application is carried out, for the most part, in an indirect way as a by-product of other more direct decisions and actions relation to the development and growth of the County. It is essential, therefore, that Polk County draw upon all possible alternative mechanisms and techniques which will lead to the effective conservation of its natural resource systems. Among the various approaches which Polk County may utilize to further its conservation objectives are the following. * * * Influence in the allocation of resources to achieve the objectives of the conservation plan. Control of events which determine resources allocation in keeping with the conservation plan. * * * Specific procedures and techniques which may be utilized to facilitate the implementation process include the following. * * * 7. Protect natural water bodies and adjacent wetland areas through the regulation of development densities and proper management of stormwater runoff. This would require a cooperative effort with the Water Management Districts in identifying flood plains for various flood frequencies. Polk County's Flood Protection and Surface Water Management Code. Polk County's Flood Protection and Surface Water Management Code was enacted as Ordinance 81-28 and was amended by Ordinance 85-07. Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code. Land Use, Density and Intensity. DCA alleges that the land use, density and intensity of the development Crowder proposes for the site is inconsistent with: (1) the section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships"; (2) a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources"; (3) Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE; and (4) Policy 2, Objective IV, "Residential Uses," in Part V of the LUE. 6/ As previously stated, the 1985 Plan is a policy plan that does not map land use classifications or densities or intensities of development. Crowder's Paradise Country Estates is consistent with the County's Zoning Code, which has not changed since before the 1985 plan, and Zoning Map. The development was not otherwise reviewed for land use, density or intensity. But it is clear that the 1985 plan does not condone exclusive resort to the zoning code to determine the appropriateness of the land use, density and intensity for development in the Green Swamp ACSC. See, especially, the section entitled "Density" in Part IV of the Conservation Element of the Plan. In the Green Swamp ACSC, especially, reference must also be made to the Plan itself. See Part VII of the LUE, entitled "Implementation." It is not found that all residential use on the Crowder property would be, in itself, inconsistent with the 1985 Plan. But, taking into consideration all of its land use, density and intensity provisions, it must be found that the development order issued in this case, especially at its level of density and intensity and especially in the manner of its issuance, is inconsistent with the 1985 Plan. The crux of the problem with this development, like others in the Green Swamp ACSC already permitted by County development orders, is that, first, the 1985 comprehensive plan and the County zoning regulations in place at the time were inadequate and, second, the steps envisioned in the plan to make them adequate have not been taken. For the plan and the zoning regulations to be adequate, and for a development order for a project in the Green Swamp ACSC in Polk County to be consistent with the 1985 comprehensive plan, either: (1) the plan must be amended to map land use classifications, densities and intensities of development in the Green Swamp ACSC; (2) the zoning code must be amended as envisioned in the comprehensive plan for the Green Swamp ACSC; or (3) the County must evaluate development orders for projects in the Green Swamp ACSC on a case- by-case basis for consistency with the comprehensive plan. None of these three possibilities happened in this case. 7/ Flood Plain Delineation. Paragraph 12 of the DCA Petition alleges that the Crowder development violates Policy 10 of Objective III, "Natural Resources," of the LUE: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Specifically, it is alleged that the use of a Federal Emergency Management Agency (FEMA) undetailed "A" zone to map the flood prone area on the site, and the failure to perform a detailed study, did not comply with the Flood Disaster Protection Act of 1973. Other allegations in the DCA Petition also implicate the delineation of the flood prone areas on the site. See, (5) Ground and Surface Water Quality, below. A FEMA "A" zone is the zone depicting the area determined by FEMA to be flood prone. In this context, FEMA defines a "flood prone" area as an area flooded in a 100-year, 24-hour storm. At the time Polk County reviewed the Crowder project for approval of the roadway and construction drainage plans, FEMA was requiring that a detailed study be performed to delineate the flood prone area. Polk County apparently was not aware of this requirement and was not enforcing it. Nor, apparently, was Crowder's engineer aware of it. In any event, Crowder did not have a detailed study performed to delineate the flood prone area on the site, and the County did not require it. In approximately March, 1992, Polk County received a written communication from FEMA advising of the requirement for a detailed study of the flood prone area in the case of developments like Crowder's. Polk County now requires compliance with this FEMA requirement. Crowder did not rely simply on the FEMA undetailed "A" zone to map the flood prone area on the site. Crowder's engineers used the existing undetailed FEMA maps as a starting point for determining base flood elevations. The engineers digitized the areas which had been designated as flood prone on the FEMA panels. The engineer then overlayed the digitized FEMA map with the on- site wetlands survey of the property, which had been field-staked and field- shot. Topographical field shots of the property which had been conducted throughout the site at one foot intervals were also overlayed on the digitized FEMA map. In addition, the engineer took into consideration mapped wetlands soils and compared flooding conditions which had occurred on adjacent property to assess whether all areas actually prone to flooding had been characterized as flood prone on the FEMA map. The methodology used by the project engineers was based on sound engineering practices. Nonetheless, it does not qualify as a "detailed study" as far as FEMA is concerned. A "detailed study" would include the application of a computer program that would "route" hypothetical flood waters onto and through the property to ascertain flood elevations in different stages of the hypothetical flood. It is not possible to determine how a detailed study would change the delineation of the flood prone area in Crowder's proposal. The total area of flood prone area could either increase or decrease; it could increase in some places and decrease in others. As it is, several of the lots platted in the Crowder development would be entirely within both the FEMA undetailed "A" zone and the flood prone area mapped by Crowder's engineers. Ground Water Recharge. DCA alleges that platting Paradise Country Estates will adversely impact recharge of the Floridan Aquifer, contrary to Policy 9 and 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. In the vicinity of the project site, the Floridan Aquifer comes to within 35 feet approximately of the ground surface. Above the Floridan Aquifer is a shallow aquifer, which rises to within approximately 12 inches of the surface. There is a layer of clastic soils (sand and clay) between the surficial aquifer and the Floridan Aquifer. This confining layer slows the rate of recharge to the Floridan. As a result, the project site is in an area having low, or even very low, to moderate recharge capabilities, at best. USGS Professional Paper 1403-E, which was released in 1990, uses groundwater modelling to quantify recharge rates, instead of using qualitative terms such as "low," or "poor," "moderate" and "high" to describe recharge capabilities. USGS Professional paper 1403-E reports that many areas in the Green Swamp previously labeled as good, moderate or high recharge areas are actually capable of only recharging at rates of 3 to 4 inches per year. The subject property appears to be in the 2 to 3 inch range per year for recharge according to USGS Professional Paper 1403-E. Only three known sample soil borings have been taken on the project site. As a result, the extent of permeability and overall thickness of the confining layer between the surficial and Floridan aquifers is not certain. But there is no reason to believe that there are any karst features or other geologic faults in the area that would allow for direct connections between the surficial and Floridan aquifers. The soil borings that have been taken on the site verify the various geological surveys and studies describing the recharge capabilities in the area. Due to the site's limited capabilities as a recharge area, it is unlikely that the platting of this site will result in any significant reduction in its natural recharge rate. The project is not inconsistent with Policy 9 or 11, Objective III, "Natural Resources," of the LUE, or Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Individual Water Well Use. DCA alleges that the planned use of individual water wells in Crowder's Paradise Country Estates will impact the quantity of the Floridan Aquifer (and the surficial aquifer) contrary to Policy 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. The potentiometric level of the Floridan Aquifer protects the Floridan Aquifer from salt-water intrusion. Significant de-watering of the aquifer caused by large municipal or industrial wells extracting a high volume of water from the aquifer at an intense rate can lower the potentiometric pressure, thus increasing the potential for salt-water intrusion into the aquifer. (Furthermore, the lowered potentiometric pressure creates a hydraulic gradient which encourages surface waters to percolate downward at a faster rate due to the decreased pressure in the Floridan Aquifer. See the preceding sections on Ground Water Recharge and the following section on Ground and Surface Water Quality.) Large municipal, industrial or agricultural wells which exceed 6 inches in diameter must obtain consumptive use permits from the SWFWMD. The Water Management District takes into account what the District determines to be a safe yield per acre when issuing a consumptive use permit. Small, residential wells are not subject to this permitting process as their impacts are much smaller and less intense, and not a concern with regard to their effect on the potentiometric pressure. For this reason, some coastal areas have begun using smaller, individual wells as an alternative to larger municipal wells. The Floridan Aquifer is replenishing itself fast enough for residential wells not to "de-water" or "draw down" the aquifer's supply of ground water. Residential wells do not lower the potentiometric pressure of the Floridan to a significant degree. Nor would they affect the normal supply of ground water, or contribute to salt-water intrusion. Pumping tests performed within two to three miles west of the project site which utilized several residential-size wells support the foregoing conclusions. For these reasons, it is found that the development will not adversely impact the normal supply of ground water and thus will not interfere with the functions of the potentiometric high of the Floridan Aquifer, including its protection against salt-water intrusion. Since the water wells would pump only from the Floridan Aquifer, they would not impact the supply of surface water. In regard to the use of water wells, the project is not inconsistent with Policy 11, Objective III, "Natural Resources," of the LUE, or with Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Ground and Surface Water Quality. DCA alleges that Paradise Country Estates will result in unacceptable contamination of the Floridan Aquifer, the surficial aquifer, and the surface water (particularly the Withlacoochee River) contrary to Policies 9, 10 and 14 of the "Water Resource Objective" of the Conservation Element. Paragraph 20 of the DCA Petition alleges that the use of individual on-site disposal systems (OSDS), or septic tank systems, in violation of Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code), 8/ in particular, will be part of the cause of the unacceptable contamination (other causes being from lawn and garden maintenance and automotive wastes.) On-Site Disposal Systems. Chapter 10D-6, Florida Administrative Code, sets forth requirements for the use of on-site waste disposal, or septic tank, systems in the State of Florida. That chapter, which is administered by the Department of Health and Rehabilitative Services ("HRS") through local health departments, provides construction standards for the installation of on-site waste disposal systems. The septic tank serves as a holding tank designed to separate solids and floatable materials and allows anaerobic digestion of organic materials. The remaining effluent exits the tank into the soil infiltrative process, which is referred to as the drainfield. The drainfield is composed of gravel placed around perforated pipes, which are designed to evenly distribute and release the effluent into soil material where the effluent undergoes aerobic digestion. Eventually, any constituents remaining in the effluent which have not been absorbed by the root zone or otherwise decomposed reach the subsurface waters which are referred to as the surficial water table. Each individual lot owner will be required to obtain a permit from the local health department prior to installing an on-site waste disposal system. Prior to issuing a permit, HRS inspects each site to assess soil limitations and to conduct a percolation test to determine the seasonal high water table for the site. Because the soils on the site are severely limited for filtration purposes and the high water table is only 10 to 12 inches below the surface, individual lot owners will be required to mound their on-site waste disposal systems to overcome these limitations. Although the fill used to mound the systems will be comprised of suitable soils, it is possible that the foreign soils will absorb moisture from the existing soils on this site, a phenomenon referred to as capillary fringe affect. This phenomenon can cause those portions of the fill which come in direct contact with the existing soils on the site to lose their filtration capabilities. Unless the fill becomes saturated from other sources, it is unlikely that capillary fringe affect will render the filtration process ineffective. The effects of capillary fringe affect can be lessened by mixing fill with soils found on the site, a practice undertaken by contractors when installing on-site waste disposal systems. In addition, increasing the amount of fill used to mound the system would decrease the potential affects of this phenomenon. 9/ Floridan Aquifer Water Quality. In some areas of the Green Swamp, the Floridan Aquifer is actually considered a surficial aquifer since no confining layers of soil or clay separate the subsurface water from the Floridan Aquifer. These areas would typically be characterized as areas with high recharge capabilities (or high potential for contamination). However, throughout the project site, a confining layer exists which is composed of clayey sands which have a very low permeability. Therefore, there is relatively little interaction between the surficial aquifer and the Floridan Aquifer on this particular site. For this reason, the use of individual on-site waste disposal systems on this site would pose no significant risk to the water quality of the Floridan Aquifer. Surficial Aquifer and Surface Water Quality.-- As for the surficial aquifer and surface water quality, Chapter 10D-6, Florida Administrative Code, requires on-site waste disposal systems be located at least 75 feet from waterbodies. Normally, and when the systems are operating properly, this assures that adequate filtration and decomposition occurs before wastewater reaches surface waters on or near the site. But, in the case of the Crowder proposal, it is necessary to consider that at least some of the mounded systems will be subjected to flooding and will become saturated. Even based on the analysis by Crowder's engineers, 51 of the lots in Paradise Country Estates are entirely flood prone; there is no place to put an OSDS on those lots that is not flood prone. If a "detailed study" had been done, it is possible that more lots would be entirely within the flood hazard zone. Other lots not entirely within the flood zone may not be able to accommodate an OSDS on the part of the lot not within the flood zone. If the OSDS mound is saturated during flood conditions, the system will fail, and untreated waste, or inadequately treated waste, will be released into the surface flood waters. This waste water will move laterally across the project site. Roots may absorb some nitrates or other organic compounds; 10/ otherwise, the waste water and its constituents will remain in the surface water. Lateral movement across the site generally will be slow, as the site is relatively flat. Some of the waste water and its constituents will get into the surficial aquifer. There are ditches or canals alongside and on the site that will direct the rest of the surface water into Pony Creek and other tributories of the Withlacoochee River, an Outstanding Florida Water approximately three and a half miles to the north. The Department of Environmental Regulation issued a dredge and fill permit for the project's road network's impact on wetlands on the site. But it did not pass on the use of OSDS in the individual lots. It also erroneously referred to the Withlacoochee as a natural Class III, instead of an Outstanding Florida Water. See F.A.C. Rule 17-302.700(9)(i). The Southwest Florida Water Management District (SWFWMD) issued a surface water management permit for the project. In evaluating a permit application, SWFWMD considers surface water quality. But the focus of SWFWMD's inquiry is the pre- and post-development peak flows. Also, when it considers water quality, SWFWMD considers the impact of site alteration on water quality, not the impact of the use of OSDS on the site. In addition, the Crowder project was reviewed under special criteria for low-density rural subdivisions that do not require the submission of as much information. It was not clear from the evidence precisely how SWFMD evaluates water quality under those criteria. For these reasons, based on the evidence, it cannot be said that the Crowder project's OSDS will be meet the minimum standard of being "located to avoid impairment to them or contamination from them during flooding," as required by Section 5-1(6) of Polk County Flood Protection and Surface Water Management Code, or that the project will "protect the normal . . . quality of ground and surface water . . . necessary for the protection of resources of state and regional concern," as required by Policy 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Finally, the project will not "protect or improve existing ground and surface-water quality," as required by Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan. Other Appeal Issues. Except as set forth above, the Crowder development did not violate the 1985 comprehensive plan and Flood Protection and Surface Water Management Code provisions cited in the DCA Petition. Agency Practice - Other Development in the Area. As previously described, Evans Acres, to the west of the Crowder site, was approved by DCA in 1983. (See Finding 10, above.) As approved, it was comprised of 48 lots on approximately 1,290 acres (a density of one unit per 27 acres). The original lots ranged in size from 5 to 60 acres. Unbeknownst to the DCA, individuals apparently have since split their lots and many of the existing lots are 2 to 5 acres in size. A proposed development known as Turkey Creek is located between the project site and Evans Acres. Turkey Creek is comprised of approximately 57 lots on 170 acres with a gross density of 1 unit per 3 acres. The physical characteristics of the Turkey Creek property, including the abundance of wetlands and floodplains, are essentially the same as the proposed project site. DCA appealed Turkey Creek in June of 1992. However, in that case, the County had been approximately two years late in rendering the Turkey Creek development order to the DCA. Meanwhile, the developer incurred development expenses and already had constructed roads and drainage facilities for the development. The developer, the County and DCA executed a settlement agreement which allows the development to proceed according to the original construction plans, but requires homeowners to install dual septic tank systems and have their septic tanks cleaned and inspected every three years. Several other developments, which are in the general vicinity of the project site and have many of the same physical characteristics, including Yearling Trace and Buck Hill, have been appealed by DCA. Yearling Trace is comprised of 108 units on approximately 544 acres. Buck Hill is comprised of 55 units on approximately 214 acres. Those projects were appealed by DCA in June and April, 1992. In some of these cases, the County did not timely render development orders to DCA in a timely manner. In the case of Buck Hill, the DCA had been mailed an unapproved copy of development plans in October, 1990; in early 1992, DCA contacted the County to inquire, as no County-approved development plans ever had been sent to the DCA. In many of these cases, substantial development expenses had been incurred; in some cases, roads and drainage facilities already had been constructed. DCA decided to settle the pending appeals in which the County was late rendering the development order, and in which the developer already had constructed roads and drainage facilities, consistent with the Turkey Creek settlement. In cases where the County was late rendering the development order, but the developer had not already constructed roads and drainage facilities, the DCA determined to settle not only for stipulations to upgrade the OSDS, as in the Turkey Creek settlement, but also for requirements that a "detailed" flood zone study be done, in accordance with the FEMA requirements. Prior to the DCA appeal, Crowder had expended approximately $31,000 in permit fees. In addition, he has incurred development costs, primarily for engineering fees and related services. Through the time of the final hearing, he had spent approximately $99,000 on engineering fees and services. (The evidence was not clear how much had been incurred by the time of the DCA appeal.) However, the County was not late in rendering the Crowder development order, and Crowder has not constructed roads or drainage facilities. In view of the different circumstances in Crowder's case, DCA's prior agency practices do not compel that Crowder's development be treated in the same manner, i.e., be settled on the same terms, as the Turkey Creek and the others. DCA has argued that FLWAC's Final Order in the case of Dept. of Community Affairs v. Narbi International Company, Inc. and Lake County, 14 FALR 3223 (1992), controls this case and requires the Crowder development order to be overturned on appeal. Narbi involved development Green Swamp ACSC, albeit in Lake County. Factually, there are many differences between Narbi and this case. The Narbi development order was a rezoning from agricultural with a residential density of up to one unit per five acres to a residential planned unit development (PUD) zoning with a density of one unit per 1.35 acres. Also, Lake County's comprehensive plan had an "urban containment policy," which DCA equated with its non-rule policy preventing "urban sprawl" or "leap-frog development." Thirdly, in Narbi, it was found that a geologic fault existed on the project site which allowed a direct connection from the surficial aquifer to the Floridan Aquifer. Because of the factual differences, Narbi does not control the outcome of Crowder's case. Conditions for Approval. Based on the testimony of its witnesses, DCA has proposed that, notwithstanding its deficiencies, the Crowder project can be approved if its density is lowered to between one unit per ten acres and one unit per 20 acres. The rationale of DCA's witnesses seems to be that the proposed lower density, in and of itself, would cure at least the most significant of the deficiencies. Since the Crowder development order under review was for approval of particular road and drainage plans, the plans would have to be redrawn at the lower density and resubmitted for approval by the County subject to the final order to be entered in this case. It is not possible for the Commission to approve, on condition of lowered density, the plans that were the subject of the development order in this case.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Florida Land and Water Adjudicatory Commission enter a final order rescinding and denying approval for the development order in this case. RECOMMENDED this 10th day of March, 1993, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 10th day of March, 1993.
The Issue The issue for consideration in the proceeding concerns whether the Petitioner is entitled to an on-site sewage disposal system permit ("OSDS") authorizing installation of an on-site sewage disposal system for property the Petitioner owns near the Suwannee River in Gilchrist County, Florida, in consideration of the relevant provisions of Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code, and whether the Petitioner should be entitled to pursue a variance from the permitting statute and rules embodied in that chapter of the code.
Findings Of Fact The Petitioner owns certain real property located in Gilchrist County, Florida on the east bank of the Suwannee River, adjoining the river. The property is more particularly described as Lot 9, Block B, Two River Estates. The property was purchased on January 3, 1985 and was platted as a subdivision on January 5, 1959. The lot in question upon which the OSDS would be installed should a permit be granted, is approximately one acre in size. On April 30, 1990, the Petitioner made application for an OSDS seeking authorization to install such a conventional septic tank and drain-field system for disposing and treating household sewage effluent on the subject property. The system would be designed to serve a single-family residence, containing approximately two bedrooms, and approximately 1,200 heated and cooled square feet of living space. Upon making application, the Petitioner was informed that he would have to obtain a surveyed elevation of his property, as well as the ten-year flood elevation for his property for the river mile of the Suwannee River at which his property is located. The Petitioner consequently retained Herbert H. Raker, a registered land surveyor, who surveyed the elevation for his property. Mr. Raker established a bench mark elevation of 29.24 feet above mean sea level ("MSL"). The site of the proposed OSDS installation on that lot has an elevation at the surface grade of 28.5 feet. The subsurface of the lot at the installation site is characterized by appropriate, "slight-limited" soil extending 72 inches below the surface grade of the lot. The wet season water table is 68 inches below the surface grade of the lot. Consequently, there is more than adequate slight-limited soil to handle disposal and treatment of the sewage effluent from a single-family residence, such as is proposed, since the wet season water table is 68 inches below the surface of the property. Thus, a more than adequate treatment space and appropriate soil beneath the bottom surface of any proposed drain field to be installed at the site would exist so as to comply with the pertinent rules cited herein. The problem with a grant of the subject permit consists only of the fact that the property lies beneath the ten-year flood elevation, that is, it is approximately 1.5 feet beneath that elevation. The Suwannee River Water Management District report submitted to the Respondent agency by the Petitioner in the application process for the OSDS permit (in evidence) reveals that the ten-year flood elevation for the property in question is 30 feet above MSL. The soils prevailing at the proposed installation site, the great depth of the wet season water table, and the fact that the lot is approximately one acre in size and above the minimum size requirements for the installation of an OSDS, all militate in favor of a grant of the permit, except for the basis for its denial initially, that is, that it is simply beneath the ten-year flood elevation for purposes of the prohibition contained in Rule 10D-6.047, Florida Administrative Code. Although located within the ten-year flood elevation, the site is not located within the regulatory flood way so that if a mounded system or other raised OSDS alternative system were proposed and installed, an engineer's certification would not be required regarding the issue of raising the base flood level by the deposition of fill at the installation site for purposes of Rule 10D-6.047(6), Florida Administrative Code. There is no central water system available to the property; however, although there was conflicting testimony about the distance the proposed installation site would be from a neighbor's potable water well, the testimony of the Petitioner is accepted as being most certain in establishing that more than the required distance from that potable water well exists between it and the proposed septic tank and drain-field installation site, since the Petitioner established that approximately 110 feet is the actual separation distance. The Petitioner purchased the property to construct a single-family residence for himself and his family. He expended a substantial sum of money for the property and is unable to use it for its intended purpose without the subject permit or at least a variance so as to authorize him to install an OSDS. The Petitioner offered no concrete proposals or plans for an alternative system which might reasonably accomplish treatment and disposal of the sewage effluent in question without harm to ground or surface waters or the public health. No substantial proof was offered of a system which would either dispose of and treat the effluent at a location above the ten-year flood elevation or, if still below it, would adequately treat and dispose of the effluent sewage to safeguard the public health and the ground or surface waters involved, such that its existence slightly beneath the ten-year flood elevation would only be a "minor deviation" from that portion of the permitting rules. In point of fact, it would seem that a mounded system would be feasible on a lot this size, especially in view of the fact that the bottom surface of the proposed drain-field trenches or absorption beds would only have to be raised slightly over 1.5 feet from the surface grade of the subject lot and installation site in order to comply with the ten-year flood elevation parameter, which was the only basis for denial of this permit application. No proof was offered concerning how such a mounded system would be designed, installed and otherwise accomplished, however. Upon denying the initial application for the OSDS permit, the Respondent advised the Petitioner that he should pursue a formal administrative hearing process rather than make application for a variance and proceed through the internal variance board mechanism operated by the department in order to obtain a variance from the requirements of Rule 10D-06.47(6), Florida Administrative Code. The Respondent advised the Petitioner of this because the subject property was located within the ten-year flood elevation of the Suwannee River; and as the Respondent interpreted the Governor's Executive Order Number 90-14, which incorporated by reference the "Suwannee River Task Force Report" commissioned by the Governor, the Order absolutely prohibited the granting of any variances authorizing installation of OSDS's beneath the ten-year flood elevation of the Suwannee River or the granting of any OSDS permits themselves authorizing such installations.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying the Petitioner's application for an OSDS permit.

Findings Of Fact Charlotte Highlands is an approximately 97-acre mobile home subdivision in Charlotte County, Florida. The roads in the subdivision are unpaved. The stormwater sheet flow in the area is from west to east. To the east of Charlotte Highlands is a 21-acre hardwood swamp, the wetlands in question in this proceeding. Stormwater from the 97-acre subdivision west of the wetlands and from the 250 acres west of the subdivision flows to the east into the wetlands. Water flows out of the wetlands to the east, from the 21-acre wetlands through a stream into Myrtle Slough. Myrtle Slough is part of the waters of the State. The County wishes to create a stormwater drainage system for Charlotte Highlands. Under the County's plan, stormwater from the 97-acre subdivision would be discharged into the wetlands owned by Desrosiers Brothers. Although the County and the Department view this project as involving only the discharge of stormwater from the 97-acre subdivision into the wetlands, the stormwater discharged would include the stormwater flowing into the 97-acre subdivision from the 250 acres located directly west of the subdivision. The County met with individuals from the Southwest Florida Water Management District, and that agency questioned the method of calculations used by the County in determining the amount of runoff into the proposed drainage system. Although new calculations of stormwater runoff volume were performed by the County, those new calculations were not provided to the Department in the County's permit application. The wetlands in question contain cypress, maples, laurel oak, bay trees, percia, dahoon holly, buttonbush, ferns, palmetto, and wet pine. Some of these species, especially the maples, cannot withstand much flooding. The outflow from the wetland into Myrtle Slough is via a natural stream. Although there are some indications that some excavation may have taken place in the stream, such as the spoil located near the cattle watering pond near the mouth of the wetlands, water flows from the wetlands to Myrtle Slough through a natural watercourse with no man-made connections. The hydroperiod is the length of time water stays in a wetlands before it drains out of the wetlands. This determines the water level, the critical factor affecting a wetland's ability to perform its vital functions. If the rate or volume of either the inflow or outflow of a wetlands is altered enough, the water level changes, usually with adverse environmental consequences. Certain species of flora will die off if the water level rises too much. Others require high water levels for their survival. In order to assess the effects of a proposed alteration to such a system, one must determine the existing high pool and low pool. Donald H. Ross established the high and low pools for the County. He went to the wetlands and observed the stain, rack, and lichen lines on tree trunks. He also observed the cypress buttress. Ross also determined the invert of the stream, the elevation at which water first starts to run in it. Based solely on this site visit, the County determined the high pool in the wetlands to be at 14.8 NGVD and the low pool to be at 14.1 NGVD. No rainfall data was collected and analyzed; no hydrological studies were performed; no observations were made over a period of time. There are two aspects of this project which can alter the hydroperiod of the wetlands. The first involves the amount of water entering the wetlands, and the second involves the amount of water leaving the wetlands. Currently, runoff from the 97-acre subdivision as well as the 250-acre area west of the subdivision drains toward the wetlands. The County intends to pave the roads in the subdivision and construct a system of swales. Although the paving will increase the impervious surface by an insignificant amount, the runoff will be delivered to the wetlands faster. Accordingly, peaks in water level will occur more suddenly with increased water arriving more quickly. Stormwatr is discharged into wetlands to take advantage of the pollutant-filtering functions of wetlands vegetation. To realize this function, the water must be held in the wetlands for a certain amount of time. The County intends to accomplish this by the installation of a control structure, known as a weir, which will regulate the amount of water leaving the wetlands. The County proposes to construct a weir on the stream between the wetlands and Myrtle Slough approximately 100 feet from the mouth of the wetlands. The top of the weir for this system will be set at 14.8 NGVD, the high pool established by Ross for the County. The weir will also have an orifice set at 14.1 NGVD, the low pool established by Ross and the County, which will allow a constant flow of water out of the wetlands at that elevation. The control structure will cause water to remain in the wetlands for a longer period of time, which will raise the water level in the wetlands by some amount. In order to accurately predict this amount, it is necessary to determine the storage capacity of the wetlands. The County calculated that a storage capacity of 177,761 cubic feet would be required for the wetlands to contain the first one-half inch of rainfall from the 97-acre subdivision. No calculations have been made as to the storage capacity required for the wetlands to contain the first one inch of rainfall from the 97-acre subdivision as well as the 250-acre area that drains into the subdivision which then drains toward the wetlands. The County has failed to establish the hydroperiod of the wetlands. Having failed to establish the hydroperiod of the wetlands, the impact of its project on the wetlands cannot be determined. As an alternative to this project the County considered rerouting the stormwater away from the wetlands. Diverting necessary water from the wetlands would result in the desiccation of the wetlands. However, an increased water flow if not properly discharged would likely result in an over impoundment of the wetlands. Either approach would have an adverse impact on a productive wetland system, such as the wetlands involved here, and a change in the vegetation would adversely impact the wetland's ability to treat the discharge. The treatment of stormwater in wetlands is a relatively new technique. Although some projects have been approved in other parts of the State, projects such as that proposed by the County have not been used yet in southwest Florida.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, RECOMMENDED that a Final Order be entered denying Charlotte County's application for a wetlands stormwater discharge facility permit.
