Findings Of Fact Respondent, Okaloosa County Board of County Commissioners, gave notice of a new storm water discharge to the Department for the proposed replacement of a 42" diameter storm water pipe with one 48" in diameter. Notice was given in letters, telephone calls and personnel meetings between representatives of Okaloosa County and the Department. Upon investigation of the project, the Department determined that the project would not significantly enlarge the storm water discharge system, nor enlarge the watershed which the system now drains. The Department also determined that the addition of an energy dissipater, a structure not now present at the discharge end of the pipe, would improve the performance of the discharge system by limiting the velocity of the storm water discharge to 2.3 feet per second. The Department determined that the new storm water discharge would not have a significant adverse impact on the water quality or designated uses of Gap Creek. On May 6, 1980, the Department issued to Okaloosa County a letter of intent to exempt the project from storm water licensing requirements. The Department considered the following in reaching its conclusion that the replacement of the existing pipe would not significantly affect water quality or designated usage: The use of an energy dissipater structure designed to limit the discharge velocity into Gap Creek to a maximum of 2.3 feet per second. The placing of sod around all storm water inlets associated with the pipe replacement to prevent the continued entry of sand into the system; and The pipe replacement and addition of the energy dissipater will not result in a significant enlargement of the existing storm water discharge system, nor otherwise result in the drainage of a larger area. The replacement of the drainage pipe by the county will not add to the amount of water entering Gap Creek, or significantly affect the quality of water in the Creek. Presently, storm water runoff travels within a county-owned drainage ditch and overflows at the point where the county intends to replace the existing 42" pipe. The present pipe is not capable of handling the amount of runoff in the ditch and this results in water overflowing the drainage ditch at the mouth of the pipe and traveling by natural contour to Gap Creek. The 48" replacement pipe and energy dissipater will allow a greater volume of water to remain in the drainage ditch and divert its flow away from the front and back yards of some Gap Creek residents.
Recommendation Upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That a final order be entered by the State of Florida, Department of Environmental Regulation, granting the applicant, Okaloosa County, an exemption from storm water licensing requirements for the installation of a 48" storm water pipe to replace an existing smaller pipe that enters into Gap Creek. DONE and ORDERED this 27th day of February, 1981, in Tallahassee, Leon County, Florida. SHARYN L. SMITH, 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 27th day of February, 1981.
The Issue The issue presented here concerns the entitlement of the Petitioner, Turtle Lake Land Trust, to be permitted by the Respondent, State of Florida, Department of Environmental Regulation, to dredge approximately 600,000 cubic yards of material in the area known as Turtle Lake, which is located near Jackson street and Fairfield Drive, Pensacola, Florida. The purpose of this project is to create a manmade lake. The dredged material world be placed on the lake shore.
Findings Of Fact On May 9, 1979, the Respondent, State of Florida, Department of Environmental Regulation, received an environmental permit application from the Petitioner, Turtle Lake Land Trust. The details of that permit application were contained in a form provided by the Department together with attachments to that form. A copy of this permit application may be found as the Respondent's Exhibit No. 2 admitted into evidence. By this application, Turtle Lake requested that it be allowed to dredge approximately 600,000 cubic yards of material in an area known as Turtle Lake, which is located near Jackson Street and Fairfield Drive, Pensacola, Florida. The purpose of the excavation was to establish a manmade lake approximately twelve (12) feet in depth in an area which is a cypress swamp and subject to periodic inundation by water. The materials removed from the dredging would be deposited on the shores of the lake, effectively raising the ground elevation at lakeside. The dredging would intersect the groundwater on the project site. The project is part of an overall development which would involve construction of residential housing and commercial facilities in the vicinity of the lake, with the lake to be used for fishing, sailing and other water recreation. The proposal of the Petitioner was reviewed by the Department and certain timely additional requests were made from the Department to the applicant to provide information necessary to evaluate the request for permit. The exhibits dealing with the request for additional information and responses to those requests may be found as Respondent's Exhibits 3, 5, 8, 9, 10 and 11 admitted into evidence. The Department solicited comments from the Florida Game and Freshwater Fish Commission on this subject and the comments were provided by correspondence from the Executive Director of the Commission. These comments may be found in Respondent's Exhibit No. 6 admitted into evidence, which is a copy of those remarks. The Department of Environmental Regulation, in keeping with the provision Subsection 253.124(3), Florida Statutes, performed a biological survey of the project site and submitted it to the Board of County Commissioners of Escambia County, Florida, for the Board's action. A copy of the survey may be found as Respondent's Exhibit No. 7 admitted into evidence. The Escambia County Board of County Commissioners, by Resolution dated October 11, 1979, approved the project subject to action by the Respondent and the United States Corps of Engineers. A copy of this Resolution may be found as the Respondent's Exhibit No. 12 admitted into evidence. Upon consideration of the permit request, the Department of Environmental Regulation notified the applicant of its intent to deny the permit request. This Letter of Intent to Deny was issued on January 31, 1980, and a copy of it may be found as Respondent's Exhibit No. 13 admitted into evidence. This matter has been presented for consideration before the State of Florida, Division of Administrative Hearings, upon referral by the Respondent of the original Petition and has been heard after opportunity for and amendment to that Petition. The hearing was conducted on September 23, 1980, as scheduled, in keeping with the provisions of Subsection 120.57(1), Florida Statutes. The project site is located in a cypress swamp which has also been referred to as a cypress head. The southern boundary of the project site east of Fairfield Drive has an impoundment area which is fringed by pine trees and other upland species, to include gallberry, southern brackin, blackberry and oak. There is within this area aquatic vegetation dominated by Eleocharis sp. and fragrant waterlily (nymphaea odorata). The cypress head itself, which is bounded on the west by Fairfield Drive, consists of cypress, blackgum, sweetbay and cinnamon fern, fragrant waterlily and pickerel weed (pontederia lanceolata). Within the zone of the cypress head standing water may be found, the dimensions and depths of which were not established at the hearing in sufficient detail to allow further comment in these findings. Fairfield Drive serves to contain the water found in the Turtle Lake swamp on the eastern side of that roadway; however, there is an exit from the cypress head under Fairfield Drive by a series of three 24-inch culverts which connect the manmade ditches. These ditches flow into Bayou Marcus and Bayou Marcus Creek and eventually into Perdido Bay. This water connection is a direct connection and Bayou Marcus, Bayou Marcus Creek and Perdido Bay are waters of the State. Immediately adjacent to Fairfield Drive east of that roadway in the vicinity the culverts water may be found standing and could be navigated and this may be seen by Respondent's Composite Exhibit No. 14. This water which although subject to navigation wad not identified sufficiently at the hearing to establish its length and breadth. The depth was two to three feet. This water adjacent to Fairfield Drive is not within that area of the proposed excavation. At present, the storm water runoff from the Forte subdivision located to the north and east of the project site, enters the cypress head swamp and at times of periodic inundation, this storm water runoff arrives at the area of the culverts into the ditch system and into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. The oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which make up the storm water constituents are somewhat filtered by the cypress head swamp as it now exists, prior to the entry of those materials into the culvert area adjacent to Fairfield Drive and from there into the transport mechanism constituted of the ditches, bayou, creek and bay. If the project is built out, the dredging will remove those flora mentioned herein and the fauna which inhabit this swamp and will remove the cypress head from future use by the fauna which normally inhabit this form of environment. It would also take away the natural filtration to be provided by the swamp in the way of removing undesirable storm water constituents from the residential runoff in Forte subdivision and the proposed development associated with the lake construction. The removal of the swamp would destroy the capacity to convert raw nutrients into usable sources of food for indigenous dawn stream organisms. As can be seen in the Petitioner's Exhibit No. 1, the existing water table at the site is approximately 23 feet and ordinary highwater elevation has been measured at 24 feet with an existing grade of 21 feet. If the lake were excavated, the lake would show a water table with an elevation of 20 feet. The berm or dykes around the lake would have an elevation of 24 feet. Storm water from the current subdivision and the residential and commercial build-out associated with the project in question would be carried through underground storm water piping into four holding areas which have been referred to by the applicant as drainage corridors and retention area. These areas are separated from the lake by siltation screens and will serve the function of filtering out some storm water constituents which are solid particulates. The constituents which have been dissolved will flow through the siltation screen devices and into the lake proper. When the lake rises to a depth of 23 feet, the excess water will he transported through a proposed ditch into the area of the three culverts under Fairfield Drive and via those manmade conveyances into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Those storm water constituents such as oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which have not settled or been filtered will be transported through this system and deposited into waters of the State. In this connection, the drainage corridor and retention areas are not designed for long-term retention; they are primarily for short-term detention, depending on the amount of loading from the storm water runoff. The only pre-treatment associated with the storm water runoff is that filtration that occurs in the drainage corridor and retention area. (There was some discussion of possible gravel filters in conjunction with the drainage corridor and retention area but they were not part of the plan submitted to the Department in the process of project review.) In addition to the introduction of the storm water contaminants into the waters adjacent to Fairfield Drive at the area of the culverts and the bayou, creek and bay, these contaminants will be introduced into the ground water in the lake proper Although some increase in retention of storm water runoff may be expected, if the project were built, there would be a significant increase in the introduction of dissolved contaminants into waters over which the Respondent has jurisdiction, i.e., Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Increases in these areas will occur in biochemical oxygen demand and undesirable nutrient and dissolved oxygen levels will decrease if this project is constructed. In association with this change, an increase in nuisance species would occur. The Petitioner has failed to do any background sampling to establish the natural background levels of the aforementioned conditions in waters of the State in order to identify whether water quality in the receiving waters would be degraded from existing conditions to the extent of violating the Department's water quality criteria.
Recommendation Based upon a full consideration of the facts as presented and the Conclusions of Law reached in this matter, it is RECOMMENDED that the Secretary of the State of Florida, Department of Environmental Regulation, deny the Petitioner a dredge and fill permit pursuant to Rule 17-4.28, Florida Administrative Code; a construction, operating and maintenance permit pursuant to Section 403.087, Florida Statutes; a ground water permit in accordance with Rules 17-3.071, Florida Administrative Code, and 17- 4.245, Florida Administrative Code; and be it further RECOMMENDED that the Secretary take no further action to require a permit(s) as might be indicated in keeping with Chapter 253, Florida statutes. 1/ DONE AND ENTERED this 22nd day of October, 1980, in Tallahassee, Florida. CHARLES C. ADAMS Hearing Officer Division of Administrative Hearings The Collins Building Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of October, 1980.
Findings Of Fact In conjunction with the preparation of plans for widening Dale Mabry Highway in Tampa, Florida, DOT in November 1985, filed a map of reservation which includes 6.49 acres owned by Petitioner. The map of reservation was filed and approved by the Hillsborough County Commission in compliance with all applicable statutes and regulations. The property in question is adjacent to the west boundary of Dale Mabry and south of the Waters Avenue intersection. The purpose of the map of reservation is to restrict building on the property for up to five years pending the filing of condemnation proceedings. DOT intends to use the area for storm water management of the runoff from the additional pacing resulting from the widening of Dale Mabry. The parent tract is 8.3 acres in size while the area encompassed within the reservation map is 6.49 acres. The entire tract is undeveloped, but to the north and south of the property along Dale Mabry Highway industrial and commercial development has occurred. The tract was acquired by the Petitioner in 1969 as an investment and has remained essentially in an undeveloped state since that time. During the period between 1969 and the present the value of the property has gradually risen until today it is sufficiently valuable to warrant development and the cost associated therewith. In the distant past most of this area in the vicinity of this property was wetlands. Prior to the acquisition of this tract by the owners, a drainage ditch, channel H, was dug through an area just west of this tract. That has had the effect of draining part of the area and has impacted on the wetlands function performed by this tract. Some dredging was done on this tract before dredge and fill laws were enacted and the area is no longer a pristine wetland. Both Channel H and the earlier demucking have caused some diminution of the property's wetlands effectiveness. No development plans have been submitted to the Department of Environmental Regulation (DER) for the development of this property. Preliminary surveys of the property conducted by DER personnel indicate approximately fifty percent of the property is wetlands and can be developed only by obtaining a dredge and fill permit from DER. Until such time as development plans are received DER will not commit itself to what developments will be permitted on land subject to DER jurisdiction. The highest elevation on this tract is adjacent to Dale Mabry highway. This area is clearly upland and can be developed without a permit from DER. The map of reservation excludes the portion of the tract running along the west Dale Mabry boundary 165 feet deep. This tract constitutes 1.81 acres (8.3 - 6.49) abutting Dale Mabry. The undeveloped tract currently performs a wetland function in that storm water runoff from the east side of Dale Mabry highway flows through a culvert under Dale Mabry in the vicinity of this property then across this property to Channel H. Similarly, storm water runoff from the west side of Dale Mabry runs south to this property thence to Channel H. Prior to selecting the Petitioner's property for ultimate condemnation to use in the storm water management program necessary for the construction on Dale Mabry, the consulting engineers on the project surveyed the area looking for appropriate sites. This site, another site at the southwest junction of Dale Mabry and Waters, and two sites east of Dale Mabry were considered. The sites east of Dale Mabry consisted of borrow pits. One was too high and would require extensive piping to transport the water to Channel H and the other already has water quality problems which could preclude water from this pit being pumped into Channel H (and from there to state waters). The property at the southwest intersection of Dale Mabry and Waters was deemed to be more valuable for commercial development and would require more development as a storm water management area than the site owned by Petitioners. Petitioner's property will require little, if any, changes to serve the intended function as a waste water management area. This will reduce the cost to DOT for so using the property. After tentatively selecting this site for storm water management the consulting engineers went to DER to obtain information on sites DER would suggest to use for storm water management purposes. DER suggested Petitioner's property and advised of water quality problems in the borrow pit. Both the Hillsborough County Environmental Protection Commission (EPC) and DER are involved in the development of environmentally sensitive areas. In 1984 the EPC advised Petitioner that one of EPC's water quality managers had stated that 85 percent of this property was developable and invited Petitioner to submit preliminary plans for developing 85 percent of the property (exhibit 2). No development plans have been submitted. Despite EPC's 1984 letter, DER exercises ultimate jurisdiction over dredge and fill permits involving wetlands and no such property can be developed exceeding that approved by DER. Accordingly, the 85 percent developable ratio used by Petitioner's witnesses is given little credence. Some three weeks before DOT filed its map of reservation Petitioner entered into a contract to sell this property for $800,000. The contract is contingent on the buyer being able to obtain the permits necessary to develop the property. Several meetings have been held between the buyer, DOT and DER personnel to discuss how the property may be developed and still serve DOT as a storm water management area. No plans for such joint use have been presented to DER. Petitioner presented one witness who opined the property was worth $1,000,000. Presumably that appraisal did not include the 1.81 acres fronting along Dale Mabry which is not included in the map of reservation. The contract to sell the property for $800,000 cash comprised the part included in the map of reservation and the tract 165 feet deep fronting on Dale Mabry. This contract which was reached in an arms length transaction indicates the price a willing buyer is willing to pay a willing seller and is a much more credible sum than is the $1 million appraisal offered by Petitioner's witness. If this witness intended his $1 million valuation to be applicable to the 8.3 acre tract, in estimating the loss to Petitioner as a result of the restrictions imposed by the map of reservation, this witness neglected to deduct the value of the 1.81 acres fronting Dale Mabry highway in reaching that calculation. This witness attempted to place a value on the loss sustained by Petitioner as a result of the inability to market the property after the filing of the map of reservation. In making this calculation he assumed 85 percent of the property to be developable and a value of $1 million. These figures are unsupported by credible evidence and the value arrived therefrom is not credible. Further, the filing of the map of reservation only restricts the issuance of a permit in connection with this property. Petitioner is free to do with the property exactly what it has done with the property since it was acquired in 1969. Although no evidence was presented that the project involving the widening of Dale Mabry in the vicinity of this property will be accomplished on a date certain, the project is scheduled to be let for bids in December 1987. Prior to commencing any work on the project condemnation proceedings for all property involved must be underway. Although this schedule is subject to change if funding is not timely provided, this is not an event expected to occur. DER requires the storm water runoff from additional paving resulting from the widening of Dale Mabry be treated before this storm water runoff is discharged into State waters. Accordingly, it is essential that DOT show capability for storm water management before this project can be approved. Section 337.241, Florida Statutes (1985), was enacted as s. 140 ch. 84-309 Laws of Florida, 1984, and amended slightly by s. 2, ch. 85-149, Laws of Florida, 1985. Some of these provisions were formerly found in s. 335.02(3) and (4), Florida Statutes. The purpose of the filing of a map of reservation is to preclude development of the property, while road construction plans are being prepared which include the use of the property, before the acquisition of the property by DOT. During construction involving the widening of US 19 in Pinellas and Pasco Counties, numerous instances arose where development of property needed for storm water management as a result of widening of US 19 commenced after plans for use of the property had been made but before condemnation of the property by DOT. This resulted in an increase in the cost of acquiring the property.
The Issue The issue is whether an Environmental Resource Permit should be issued to Luther E. Blake, Jr. and Irene Blake Caudle authorizing the construction of a stormwater management system to serve a single-family development known as Walnut Creek, Phases I and II, in Gainesville, Florida.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background In this environmental permitting dispute, Respondent, St. Johns River Water Management District (District), proposes to issue an Environmental Resource Permit to Respondents, Luther E. Blake, Jr. and Irene Blake Caudle (Applicants), authorizing the construction of a stormwater management system to serve Phases I and II of a single-family development known as Walnut Creek Subdivision in Gainesville, Florida. The system will be located on a 31-acre, L-shaped parcel of undeveloped, forested land. The proposed system includes a 135-lot single family subdivision, internal roadways with curb and gutter, a storm sewer system, and five dry retention ponds. The project site is located west of Northwest 13th Street (Highway 441) in the northwestern portion of the City of Gainesville between Northwest 39th Avenue (State Road 222) and Northwest 31st Boulevard, west of Palm Grove Subdivision, and east of Hidden Pines Subdivision. Petitioner, Glen Springs Preservation Association, Inc. (Association), is a corporation made up of an undisclosed number of persons, at least one of whom resides adjacent to or near the proposed project site. Petitioner, Elizabeth T. Furlow (Furlow), who did not indicate that she is a member, also resides with her husband near the project site. As set forth in the parties' Prehearing Stipulation, Petitioners contend that the proposed system fails to meet certain design and performance criteria, that the Applicants have failed to submit the appropriate documentation to satisfy the operation and maintenance entity requirements, and that the Applicants have failed to provide reasonable assurance that the system meets the general requirements for issuance of a permit. More specifically, they contend that the requirements of Rules 40C-42.023(1)(a)-(c), 40C-42.025(1), (3), (4), (5), (6), (7), (8), and (10), 40C-42.026(1)(a), (c), and (d), and 40C- 42.027, Florida Administrative Code, have not been met.2 On these technical issues, the parties have presented conflicting expert testimony, and the undersigned has accepted the more credible and persuasive testimony, as set forth in the findings below. Respondents have not stipulated to Petitioners' standing. Through the testimony of Furlow's husband, it was established that the Furlows live just south of the project site, approximately 100 yards north of Northwest 31st Boulevard near a creek known as Glen Springs Creek (Creek). The Furlows fear that if a permit is issued, runoff from the project site will cause further erosion of the Creek's banks and flooding during rainfall events. Although three persons who live adjacent to or near the project site appeared as witnesses, only one (Bonnie O'Brien) indicated that she is a member of the Association. Ms. O'Brien has lived just west of the Creek since 1969, around one-half mile from the project site. Over the years, and due to erosion caused by increasing development in the area, much of which began before the District began permitting stormwater systems, the Creek's banks have increased in depth from around a foot or so to as much as six feet. During large storm events, the Creek's waters rise up to as much as five feet in depth. Like the Furlows, Ms. O'Brien fears that runoff from the project will go into the Creek and adversely affect her property. There was, however, no evidence concerning the Association's interests, whether the Association is a Florida corporation, the number of members in the Association, and except for Ms. O'Brien, whether any of its members are substantially affected by the proposed activity.3 Design and performance criteria The Applicants propose to use a dry retention system consisting of five dry retention ponds ranging in depth from three to four and one-quarter feet which will be located mainly along the western boundaries of the project site. In general terms, stormwater runoff from the residential lots will sheet flow to roadways and alleys, will be collected by curbs and gutters, and then will be conveyed to the five ponds for water quality treatment. Rule 40C-42.025(1) requires that "[e]rosion and sediment control best management practices shall be used as necessary during construction to retain sediment on-site." The more persuasive evidence shows that the applicants have done so, and that the best management practices used by the Applicants are generally utilized throughout the development community. Therefore, the requirements of this rule have been met. Rule 40C-42.025(3) provides that unless applicable local regulations are more restrictive, "[n]ormally dry basins designed to impound more than two feet of water or permanently wet basins shall be fenced or otherwise restricted from public access." The proposed retention basins that have three-to-one (horizontal: vertical) side slopes will be fenced to prevent public access. The evidence also shows that there are no applicable, more restrictive local regulations. Under Rule 40C-42.025(4), "[a]ll stormwater basin side slopes shall be stabilized by either vegetation or other materials to minimize erosion and sedimentation of the basins." As to this requirement, the evidence establishes that all of the stormwater basin side slopes will be stabilized by vegetation to minimize erosion and sedimentation of the basins, as required by the rule. Further, the proposed retention basin side slopes are four-to-one and three-to-one. Slopes of this dimension are typically stable and will not easily erode. Rule 40C-42.025(5) requires that the systems be designed so that they "accommodate maintenance equipment access" and "facilitate regular operational maintenance." The evidence shows that the Applicants own the entire project site, and each of the five retention ponds can be accessed from roads and alleys within the project site. Rule 40C-42.025(6) requires that an applicant "obtain sufficient legal authorization as appropriate prior to permit issuance for stormwater management systems which propose to utilize offsite areas to satisfy the requirement in subsection 40C-42.023(1), F.A.C." Because the Applicants are not proposing to use any offsite areas for the system, and the system is located entirely on the project site, no "legal authorization" from other persons is required. Under Rule 40C-42.025(7), the system "shall provide gravity or pumped discharge that effectively operates under . . . [m]aximum stage in the receiving water resulting from the mean annual 24-hour storm." Calculations performed by the Applicants, and verified by the District's independent calculations, show that the system is designed to retain all of the runoff from the mean annual 24-hour storm event. Therefore, this rule has been satisfied. Rule 40C-42.025(8) provides that if a system serves a new construction area with greater than 50 percent impervious surface, an applicant is required to demonstrate that "post- development peak rate of discharge does not exceed the pre- development peak rate of discharge" for the mean annual 24-hour storm event. If the system serves a new construction area with less than 50 percent impervious surface, however, the requirements of this rule do not apply. The evidence shows that the proposed retention system will serve a new construction area (around 12 acres) with less than 50 percent impervious area. Therefore, the rule does not apply. Even so, the Applicants demonstrated that the post- development peak rate of discharge from the project site will not exceed the pre-development peak rate of discharge for the 24-hour storm event. In fact, the post-development peak rate of discharge from the project site during the 24-hour mean annual storm event will be zero. Finally, Rule 40C-42.025(10) requires in part that the construction plans and supporting calculations be "signed, sealed, and dated by an appropriate registered professional." The evidence shows that the final set of plans submitted in January 2002 by the Applicants was signed and sealed by H. Jerome Kelly, a professional engineer.4 Specific design and performance criteria Rule 40C-40.026(1)(a) requires that the retention system provide retention of stormwater runoff in one of four ways. Here, the Applicants have designed the system to provide "[o]n-line retention of an additional one half inch of runoff from the drainage area over the volume specified in subparagraph 1. above." Subparagraph 1. requires "[o]ff-line retention of the first one half of runoff or 1.25 inches of runoff from the impervious area, whichever is greater[.]" Because the system will provide on-line retention of a minimum of one inch of runoff from the project area, plus 1.25 inches of runoff from the impervious soil in the project/drainage area, it is found that the capacity of the proposed retention system is more than adequate to capture the quantity of stormwater runoff required by this rule. Under Rule 40C-42.026(1)(c), the system must be designed to "[p]rovide the capacity for the appropriate treatment volume of stormwater specified in paragraphs (a) and (c) above, within 72 hours following the storm event assuming average antecedent moisture conditions." To assure compliance with this rule, and to demonstrate that the system meets the required recovery of the water quality treatment volume, the District performed modeling to predict the vertical infiltration rate and the groundwater mounding effects of the proposed retention system. For the reasons stated below, it is found that the system will provide the required amount of treatment volume capacity within 72 hours of a storm event assuming average antecedent moisture conditions, as required by the rule. The District used one of the latest versions of the MODRET computer modeling program, a methodology routinely used by the District to support an application for this type of retention system. That program takes into account vertical percolation into the soil; once the water reaches the water table, the model then takes into account the lateral or horizontal movement of the water out of the pond. The model is used to determine whether the required water quality treatment volume, which is significantly less than the storage volume in the ponds, will draw down within three days. The modeling confirmed that this requirement will be satisfied. Data from the Applicants' on-site soil survey was used in the model to establish the depth below ground surface of the seasonal high water table level. This resulted in a conservative assumption of an above-normal average antecedent moisture condition beneath the retention ponds. The Applicants also collected soil samples from the project site, including those areas where the retention ponds will be located, and they performed laboratory tests in accordance with ASTM D2434 to calculate the vertical hydraulic conductivity and the horizontal hydraulic conductivity for those soils. The results of both tests fall within accepted ranges as stated in the published soils texts and governmental soils surveys for the project area. In addition, the Applicants conducted an independent test to determine the mean seasonal high water table on the project site. Based on visual observations of the soil samples, the Applicants determined that the mean seasonal high water table is between six and seven feet below ground surface. The visual observation of the soil samples is compatible with the results of Petitioners' soil augers obtained off the project site. As noted earlier, the proposed retention ponds will have a depth of three to four and one-quarter feet, which places the bottom of the ponds above the mean high water table as determined by the Applicants' calculations and as stated in the soils survey for Alachua County. Therefore, the dry retention ponds should not be considered impervious surfaces. Finally, Rule 40C-42.026(1)(d) requires that the retention system "[b]e stabilized with pervious material or permanent vegetation cover." The evidence shows that the proposed retention system will be stabilized with permanent vegetative cover. Other requirements and concerns Runoff from other developed properties in the vicinity of the proposed project site discharges into the Creek, contributing to erosion in the Creek. Not all of these existing developments have stormwater management systems on-site, since some of the older properties were built before the District assumed regulation over this activity. The proposed system can be effectively operated and maintained without causing or exacerbating the erosion problems that currently exist within the Creek system. This is because once the system is built, the amount of runoff leaving the site will be less than what is now present in the pre-development state. Thus, the project, as now designed, will not adversely affect drainage and flood protection on adjacent or nearby properties. Through the submission of a copy of the Articles of Incorporation and Declaration of Covenants for the Walnut Creek Homeowner's Association, the Applicants demonstrated that the District's requirements regarding the operation and maintenance of the proposed system after completion of construction will be met, as required by Rule 40C-42.027(4).
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the St. Johns River Water Management District enter a final order granting application number 42-001- 71000-1 of Luther E. Blake, Jr. and Irene Blake Caudle for an Environmental Resource Permit. DONE AND ENTERED this 14th day of February, 2002, in Tallahassee, Leon County, Florida. ___________________________________ DONALD R.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant fact are found: On May 3, 1989, Cersosimo submitted an application for a Management of Surface Water Permit to the District. Subsequent to the submission of this application, the Polk County Board of County Commissioner (Commissioners) added an additional requirement to Cersosimo's Planned Unit Development (PUD) that there was to be a pre- development/post-development match for basin runoff in the event of a twenty- four hour one hundred (100) year storm event, i.e. following completion of this project (post-development) it will handle the same outflow or flow of storm water for the twenty four-hour one hundred-year storm event as in a pre- development situation. Based on the Commissioners' requirement, the design of the PUD was amended to provide for the required storage capabilities. On July 26, 1990, Cersosimo submitted to the District, its amended application, Management of Surface Water Permit No. 405733.01 incorporating the changes necessitated due to the Commissioners' additional requirement as to storm water runoff. On August 24, 1990, Ramon E. Monreal, P.E., of the Polk County Engineering Division, noted in a letter of that same date referring to Cersosimo's modification of Retention Pond No. 300 for the project in question that "this revision appears to meet the PUD condition by the Board of County Commissioners for drainage and compliance with the Surface Water Management Ordinance". The application of July 26, 1990, amends the original application by superceding and replacing that application. In connection with the application for permit, soil borings were taken at the site location for the retention ponds in order to establish the elevation of the seasonal high water level (SHWL) for that site. The borings indicated an elevation for the SHWL of 110 feet to 112 feet above mean sea level (AMSL). The District conservationally established the elevation for the SHWL of this particular site as 112 feet AMSL. The floor elevation of the lowest retention pond was established at 114.00 feet AMSL. The elevation of the surface of Lake Mabel for the ten year flood warning Level is 114.50 feet AMSL as established by Rule 40D-8.624(1)(z), Florida Administrative Code. District policy requires the floor elevation of a dry retention pond to be a minimum of one foot above the established elevation of the SHWL of that particular site. Even though the surface elevation of Lake Mabel for the Ten Year Flood Warning Level was established as 114.50 feet AMSL, there is insufficient evidence to show that there was lateral migration of water from the lake's edge to the site of the soil borings such that it was evidenced by a demarcation in the soil profile. To the contrary, the evidence shows that there were demarcations in the soil profile to establish an elevation for the SHWL for this site of 110 feet to 112 feet AMSL. The designed weir crest in the lower retention pond, Pond No. 300, has an approximate elevation of 118.50 feet AMSL which prevents water from coming over the top into the pond in the event Lake Mabel reaches the ten year flood level warning elevation of 114.50 feet AMSL. The distance from the present water edge of Lake Mabel to the bottom of Pond No. 300 would be approximately 600 feet, laterally and if the lake reached the ten year flood level warning elevation of 114.50 feet AMSL, the lake's water edge would be approximately 100 feet laterally from the bottom of Pond No. 300. There was sufficient evidence to show that even if the surface elevation of Lake Mabel reached the ten year flood level warning of 114.50 feet AMSL and the SHWL (ground water level) reached 112 feet AMSL, the retention ponds as presently proposed with a floor elevation of 114.00 feet AMSL would still percolate sufficiently, even though the percolation may be diminished from what it would be under present conditions, so that there would still be a pre- development/post-development match for basin runoff. Cersosimo can give reasonable assurances that the surface water management system as presently proposed will not diminish the capabilities of Lake Mabel to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code. Among others, the following specific conditions in pertinent part will be placed on the permit, if granted: . . . The applicant shall visually monitor the ponds on a monthly basis to ensure that the ponds are dry within 36 hours from the end of the last rainfall event. Should the ponds fail to percolate the required water quality volume per District criteria, a permit modification shall be required. . . .

The Issue The central issue in this case is whether the application for a surface water management permit (permit no. 4-009-0077AM) filed by the Respondent, David A. Smith (Applicant), should be approved.
Findings Of Fact Based upon the prehearing stipulations of the parties, the testimony of the witnesses, and the documentary evidence received at the hearing, the following findings of fact are made: The Applicant is the owner of the subject property. The Applicant filed an application for a permit to construct a stormwater management system which was proposed to serve a residential and golf course development to be known as Sabal Hammocks. The site of the proposed project is approximately 720 acres in size and is located in township 24 south, sections 28, 29, 30, 32, 33, and 34, range 35 east, Brevard County, Florida. The entire project site for the Sabal Hammocks development is located within the boundaries of the St. Johns River Water Management District. To the west of the project site is an 140 acre public park that treats its own stormwater and releases pre-treated stormwater during some storm events into the canals on the Sabal Hammocks site. The Applicant's site is located adjacent to Lake Poinsett and prior uses of the land have included cattle grazing and the cultivation of rye and oats. The Applicant filed his application for the stormwater management permit (permit NO. 4-009-0077AM) on December 22, 1989. That application was deemed complete by the District on June 19, 1990. The District issued a notice of its intended action to approve the permit application on June 28, 1990. Save timely filed a petition challenging the proposed action. By law the District is the appropriate agency charged with the responsibility of reviewing applications for stormwater management permits within the subject area. Save is an association of individual persons and representatives from groups who utilize the waters of Lake Poinsett and its surrounding areas for recreational and business purposes. The receiving waters for stormwater discharge from the proposed Sabal Hammocks development will be Lake Poinsett. That water body is classified as Class III waters. Currently, a dike system exists along the southern boundary of the subject property. That dike system separates the internal grazing lands of the parcel from the lower marsh and flooded areas external to the dike. A series of ditches cross the parcel to drain the interior areas. Two agricultural discharge pumps are currently in use at the site. The operation of those pumps has been authorized pursuant to a consent order approved by the District's governing board on December 13, 1990. The dike system on the subject site has been in place since the 1970s. The original construction specifications of the dike are unknown. Sometime in the 1980s, several openings or breaches were cut in the dike system. Those breaches were opened pursuant to permits issued by the District and the Department of Environmental Regulation (DER) . The breaches were cut to a sufficient width and depth to allow boats to navigate through to interior areas of the subject property during those times when the water levels outside the dike would allow such entrance. The breaches were not cut to ground level and the original dike remained intact and uncompromised by the breaches. That is, the dike has not failed to impede water movement and the integrity of the dike was not weakened by the breaches. The original outline, dimension of the dike, remained visible despite the breaches. In 1986, the Applicant requested permission from the District staff in order to close or restore the dike breaches. At that time, the District staff advised David Smith that a permit would not be required to restore the dike since such improvements would be considered a maintenance exemption. Subsequently, and in reliance upon the representations made by the District's director,, the Applicant closed the breaches and restored the continuity of the dike system of the subject property. The Applicant's work to close the breaches was performed in an open manner, would have been visible to persons using the adjacent marsh or water areas for recreational purposes, and was completed at least one year prior to the application being filed in this case. Neither the District nor DER has asserted that the work to complete the original dike in the 1970s, nor the breaches completed in the 1980s, nor the restoration of the breaches in 1986 was performed in violation of law. Further, the District had knowledge of the subject activities. Save contends that the restoration of the dike system was contrary to law and that it was not afforded a point of entry to contest the closure of the breaches. Additionally, Save infers that the original construction of the dike system in the early 1970s was without authorization from authorities. Save's contention is that the prior condition of the property, ie. the parcel with breached openings, must be considered the correct pre- development condition of the land. The District, however, considered the pre- development condition of the parcel to be that of a diked impoundment separated from Lake Poinsett. The same assumption was made regarding the pumping of water from the area enclosed by the dike via an existing 36 inch pump which discharges to Bass Lake (and then to Lake Poinsett) and an existing 12 inch pump that discharges into the marsh areas adjacent to the property (between it and Lake Poinsett). The District's consideration of the site and the application at issue was based upon the actual condition of the land as it existed at the time this application was filed. The pre-development peak rate and volume of discharge from the site was calculated based upon the maximum discharge capacity of the two existing pumps (described above). Accordingly, the maximum pre-development rate of discharge from the two existing pumps is in the range of 90-107 cubic feet per second. The pre-development volume of discharge, based upon actual pump records, was calculated as 710 acre-feet for a 25 year, 96 hour storm event. The total areas encompassed by the Applicant's proposal are the 720 acre site where the golf course and residential homes will be located together with 140 acres from an adjacent public park. The runoff entering the stormwater system from that public park will have already been treated in its own stormwater management system. The Applicant's proposed stormwater system will consist of a series of lakes and interconnected swales. This wet detention system will capture the runoff and direct its flow through the series of swales and lakes via culverts. The waters will move laterally from the northwestern portion of the parcel to she southeastern end of the site. From the final collecting pond, she waters will be pumped to Bass Lake and ultimately flow to Lake Poinsett. Wet detention systems generally provide greater pollutant treatment efficiencies than other types of stormwater treatment systems. The maintenance associated with these systems is also considered less intensive than other types of treatment systems. The wet detention system proposed for Sabal Hammocks accomplishes three objectives related to the flow of stormwater. The first objective, the collection of the. stormwater, requires the creation of several lakes or pools into which water is directed and accumulates. The size and dimension of the lakes will allow the volume of accumulated water to be sufficient to allow stormwater treatment. The capacity of the lakes will also provide for a sufficient volume to give adequate flood protection during rainfall events and storms. The second objective, the treatment of the stormwater, requires the creation of a littoral zone within the system. The littoral zone, an area of rooted aquatic plants within the lakes or ponds, provide for the natural removal of nutrients flowing into the system. The plants serve as a filtering system whereby some nutrients are processed. The proposed littoral zone in this project constitutes approximately 37 percent of the detention system surface area and therefore exceeds District size requirements. The depth of the treatment volume for the proposed system will not exceed 18 inches. A third objective accomplished by the creation of the series of lakes is the provision for an area where pollutants flowing into the detention system may settle and through sedimentation be removed from the water moving through the system. The average residence time estimated for runoff entering the Sabal Hammocks detention system is 48 days. The permanent pool volume will, therefore, be sufficient to assure the proposed project exceeds the District's requirements related to residence time. The design and volume of the Sabal Hammocks system will also exceed the District's requirements related to the dynamic pool volumes. In this case the Sabal Hammocks system will provide for approximately 65 acre-feet of runoff. Thus, the proposed system will adequately control and detain the first 1 inch of runoff from the site. The length to width ratio for the proposed lakes, 18:1, exceeds the District's minimum criteria (2:1). The final lake or pond into which the stormwater will flow will be 17 acres and will have 15 acres of planted wetland vegetation. Before waters will be released into Bass Lake, the site's runoff will pass through 3100 linear feet of this final lake before being discharged. The proposed project will eliminate the two agricultural pumps and replace them with one pump station. That station will contain four pumps with a total pumping capacity of 96 cubic feet per second. Under anticipated peak times, the rate of discharge from the proposed single station is estimated to be less than the calculated peak pre-development rate of discharge (90-107 c.f.s.). The estimated peak volume of discharge will also be lower than the pre-development discharge volumes for the comparable storm events. The proposed pump station is designed to be operated on electrical power but will have a backup diesel generator to serve in the event of the interruption of electrical service. Additionally, the pumps within the station will be controlled by a switching device that will activate the pump(s) only at designated times. It is unlikely that all four pumps will activate during normal rainfall events. The Applicant intends to relinquish maintenance responsibilities for the stormwater system including the pump station to Brevard County, Florida. Finished floor elevations for all residential structures to be built within the Sabal Hammocks development will be at a minimum of 18.2 mean sea level. This level is above that for a 100 year flood. The floor elevations will be at least one foot above the 100 year flood elevation even in the event of the dike or pump failure or both. Finished road elevations for the project will be set at 17.5 feet mean sea level. This elevation meets or exceeds the County's requirements regarding the construction of roadways. It is estimated that the Sabal Hammocks system will retain at least 26 percent of all storm events on site. If the lake system is utilized to irrigate the golf course the proposed system could retain 45 percent of all storm events on site. Of the 31.27 acres of wetlands within the proposed site, only 4.73 acres of wetlands will be disturbed by the construction of this project. Some of the wetlands are isolated and presently provide minimal benefits to off-site aquatic and wetland dependent species. No threatened or endangered species are currently utilizing the isolated wetlands. The areas of wetlands which are productive and which will be disturbed by the development will be replaced by new wetlands to be created adjacent to their current location at a lower elevation. The new wetlands should provide improved wetland function since those areas will be planted with a greater diversity of wetland plant species. Additionally, other wetland areas will be enhanced by the removal of invader species and increased hydroperiod in the area. The integrated pesticide management plan for the proposed project will be sufficient with the additional condition chat use of Orthene, Subdue, and Tersan LSR will be authorized when approved insecticides or fungicides have not been effective. In this case, the estimates regarding the water quality for the proposed project were based upon data from studies of multifamily residential projects. Data from single family/ golf course developments was not available. Therefore, based upon the data used, the projected runoff concentrations for this project should over estimate pollutants and are more challenging to the treatment system than what is reasonably expected to occur. In this regard, the overall treatment efficiencies are estimated to be good for all of the parameters of concern with the exception of nitrogen. The projected increase in nitrogen, however, will not adversely impact the receiving water body. The projected average concentration for each constituent which may be discharged is less than the state standard with the exceptions of cadmium and zinc. In this regard, the District's proposed conditions (set forth in the District's exhibits 4 and 9) adequately offset the potential for a violation of state water quality standards. More specifically, the use of copper-based algaecides in the stormwater management system should be prohibited; the use of galvanized metal culverts in the stormwater management system, or as driveway culverts, should be prohibited; and the use of organic fertilizers or soil amendments derived from municipal sludge on the golf course should be prohibited. Additionally, a water quality monitoring plan should be implemented by the Applicant. The monitoring plan mandates the collection of water samples from areas in order to adequately monitor the overall effectiveness of the treatment facility. The source of cadmium is not be expected to be as great as projected since the most common source for such discharge is automobiles. It is unlikely that the golf course use will generate the volume of discharge associated with automobile use that the multifamily data presumed. The projected quality of the discharges from this project should be similar to the ambient water quality in Lake Poinsett. In fact, the post- development pollutant loading rates should be better than the pre-development pollutant loading rates. The discharge from the proposed Sabal Hammocks project will not cause or contribute to a violation of state water quality standards in Lake Poinsett nor will the groundwater discharges violate applicable state groundwater quality standards. The floodways and floodplains, and the levels of flood flows or velocities of adjacent water courses will not be altered by the proposed project so as to adversely impact the off- site storage and conveyance capabilities of the water resource. The proposed project will not result in the flow of adjacent water courses to be decreased to cause adverse impacts. The proposed project will not cause hydrologically-related environmental functions to be adversely impacted The proposed project will not endanger life, health, or property. The proposed project will not adversely affect natural resources, fish and wildlife. The proposed project is consistent with the overall objectives of the District.
Recommendation Based upon the foregoing, it is RECOMMENDED: That the governing board of the St. Johns River Water Management District enter a final order approving the application for permit number 4-009-0077AM with the conditions outlined within the District's exhibits numbered 4, 8, and 9 and as previously stated in the notice of intent.

The Issue Whether Respondent's statements as set forth in the First Amended Petition to Determine Validity of Agency Statements Defined as Rules are rules as defined in Section 120.52(15), Florida Statutes, which have not been promulgated as required by Section 120.54(1)(a), Florida Statutes.
Findings Of Fact Petitioner alleges that the following constitute agency statements defined as rules but not properly adopted as rules by the District: The District considers a particular parcel of property to be located within a "floodway" within the District's regulatory jurisdiction for Works of the District (WOD) permitting on the basis of the parcel being located within a floodway established pursuant to a currently-approved Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The District will not accept any alternative floodway boundaries that are inconsistent with those established in the FIS unless FEMA confirms that the alternative boundaries are more accurate than those obtained from the existing FIS, and FEMA approves the alternative boundaries through a formal approval process, such as a Letter of Map Revision that also requires local government concurrence. If the District determines the parcel to be within its regulatory floodway, it will require an Environmental Resource Permit (ERP) application for any development activities within the floodway, other than those entitled to a general permit under Rule 40B-4.3010, Florida Administrative Code. The District will require an ERP for the activities described in paragraph "c" notwithstanding the fact that the Department is evaluating those same activities as part of an ERP application that has been submitted to the Department of Environmental Protection (Department) for the same activity in the same location under the terms of the Operating Agreement.1/ The District will evaluate an application to conduct development activities as described in paragraph "c" based upon the full range of ERP permitting criteria contained in the District's rules, even though the Department is processing an ERP application for the same activities pursuant to the Operating Agreement between the District and the Department. The District's policy is to deny or to object to the issuance of any permit application to conduct commercial mining operations in the WOD composed of the Alapaha River floodway. It is the policy of the District to consider any proposed development activity in a WOD, other than those eligible for a general permit under Rule 40B-4.3010, Florida Administrative Code, to have an adverse impact on the regulatory floodway, and thereby to be unpermittable by the District. The District's policies against allowing development activities in WODs apply even if a professional engineer certifies under Rule 40B-4.3030, Florida Administrative Code, that the activity will not violate the conditions of issuance set forth in the rule. The policies apply because the District will consider the development activities to violate ERP permitting rules applicable to all development activities, not just those within WODs. It is also the District's policy to ask the Department to deny ERP applications for development activities proposed in WODs that require ERPs even though the Department is processing the application pursuant to the Operating Agreement. The District's policy is to deny ERP applications to conduct commercial mining activities in WODs as determined by the FIS, and to recommend to the Department that ERP applications to the Department for such projects be denied, unless the applicant goes through the FEMA amendment process described in paragraph b to remove the area from the FEMA- determined floodway. Each party requests that it be granted costs and attorney's fees pursuant to Section 120.595(4), Florida Statutes. Stipulated Facts Angelo's is a Florida Limited Partnership, whose address is 26400 Sherwood, Warren, Michigan 48091. Respondent is an agency of the State of Florida established under Chapter 373, Florida Statutes, with its address at 9225 County Road 49, Live Oak, Florida 32060. Angelo's owns property in Hamilton County approximately four miles to the east of Interstate 75 and to the north of U.S. Highway 41, immediately to the east of the Alapaha River. Angelo's conducts commercial sand mining operations on a portion of its property pursuant to various agency authorizations, including an ERP issued by the Florida Department of Environmental Protection (Department), Permit No. 158176-001, and a Special Permit issued by Hamilton County, SP 98-3. The ERP was issued by the Department pursuant to its authority under Chapter 373, Part IV, Florida Statutes. Angelo's mining operations constitute a "mining project" as that term is used in Section II.A.1.e of an Operating Agreement Concerning Regulation under Part IV, Chapter 373, Florida Statutes, and Aquaculture General Permits under Section 403.814, Florida Statutes, between Suwannee River Water Management District and Department of Environmental Protection (Operating Agreement). The Operating Agreement has been adopted as a District rule pursuant to Rule 40B-400.091, Florida Administrative Code. Angelo's has filed with the Department an application to modify its ERP to expand its sand mining operations into an area of its property immediately to the west of its current operations (the "proposed expanded area"). Angelo's application is being processed by the Department at this time. Angelo's ERP modification application is being processed by the Department under the Operating Agreement. The District has asserted permitting jurisdiction over the proposed expanded area because the proposed sand mining activities would occur in what the District asserts to be the floodway of the Alapaha. The District asserts that an ERP would be required from the District so that the District can address the WOD impacts. It is the District's position that the District's review of any ERP application to undertake development activities in a WOD would be based upon all of the ERP criteria, and not just those criteria relating to floodway conveyance referenced in Rule 40B-4.3030, Florida Administrative Code. On or about November 30, 2001, the District published in the Florida Administrative Weekly a notice of its intent to adopt the FEMA Flood Insurance Rate Maps (FIRM) to delineate floodways for the purpose of its works of the district regulatory program. Facts Based on Evidence of Record Background/Events leading up to this dispute The total amount of the subject property owned by Petitioner is approximately 560 acres. The property is generally a rolling terrain. A significant feature is a man-made berm which was placed around the perimeter of the property by a former owner, presumably to keep water off of the land during floods of the Alapaha River. Dennis Price is a self-employed registered professional geologist. At one time, he was employed by the District and at another time, he was employed by Petitioner. For purposes of this proceeding, he was hired by Petitioner as a consultant for certain permitting projects including the project that gave rise to this dispute. Mr. Price met with and corresponded with the District as well as staff from the Department over a period of two years regarding this mining project. In June of 1999, the Department wrote to Mr. Price in response to a meeting. The letter noted that Petitioner intended to expand mining operations. In addition to informing Mr. Price of the Department's permit requirements, the letter referenced the District's permitting requirements: Mr. Still provided us with an aerial photograph showing the SRWMD's regulated floodway in the area of your mine. A copy is enclosed with the floodway line highlighted in orange. A substantial portion of your proposed expansion area will be within this floodway. The SRWMD has adopted the Alapaha River and its floodway as a works of the district. The Department adopted the SRWMD's regulations pertaining to the environmental resource permit; however, this did not include the regulations pertaining to projects within works of the district. If your permit application only includes areas outside of the floodway, a single application will have to be provided to this bureau. If you intend to expand within the floodway, a separate application will also have to be provided to the SRWMD for a works of the district permit. In either situation, the Department's Jacksonville office will review any modifications to your industrial wastewater permit. (emphasis supplied)2/ In response, Mr. Price wrote to the Department in July of 1999 and stated in pertinent part: Dear Mr. Neel, this letter is in response to your June 22, 1999 letter "RE: Permits for Mining Operation". Angelo's currently has a Sand and Limestone General Permit from DEP - General Permit Number FLA011635. That permit is based on a 5 year mining plan that was presented to the DEP on January 11, 1999. The permit, my letter and the 5 year mining plan presented to DEP are enclosed. Another attachment is an aerial photo of the property showing the Regulatory Floodway line and the location of the areas to be mined under that 5 year mining plan. The aerial photograph has superimposed upon it the location of the floodway of the Alapaha River, as determined by FEMA maps. Please note that the 5 year mining plan and the associated storage and processing areas are outside the regulatory floodway. Therefore, no works of the district permit will be needed at this time. See FAC Rule 40B-4.300(1)(a) [sic]. Future mining beyond the five year mine plan will not occur without first applying for and obtaining permits from the appropriate regulatory agency. At the present time we will only mine areas within the 5 year mine plan. We will have an engineer field locate the floodway line on the property to ensure that no mining or associated storage and process activities occur within the floodway. We are requesting that the ERP permitting process remain within the DEP bureau of Mine Reclamation since the DEP has already issued a general permit for this activity and the DEP normally handles ERP's for mining operations. We have determined that the mining area will be less than 100 acres, and based on Rule 40B-4.2020(2)(B) FAC a general permit may be applied for. We will notify you when we have a draft application prepared and would like to meet with you at your earliest convenience after that to discuss the permit application. (emphasis supplied) In response to information which Mr. Price provided to the Department, the Department wrote to Mr. Price in December of 1999 and again addressed concerns about the area of the project in relation to the floodway line: Specific Item: FLOODWAY Information submitted in response to the request for additional information (RAI) dated August 12, 1999, indicates that Angelo's proposed project boundary and activities extend up to and coincide with the Floodway Line. There appears to be no set-back or buffer from the Floodway (or any other) Line. Chapter 40B-4, Florida Administrative Code (F.A.C.), contains the rules for the Suwannee River Water Management Area which were adopted by the Department of Environmental Protection. Section 40B-4.2010(2)(b)(3)(b) provides that a General Permit may be issued for construction, operation, and maintenance of a surfacewater management system servicing a total project area less than 120 acres provided the system will not be located in, cross or connect to a work of the district. Information submitted with this (November 12, 1999) submittal indicates that the proposed activities within the proposed project coincides with, or is so closely located to, the Floodway Line so as to indicate that the proposed activities would be considered to be connected to a work of the district. This is based upon examination of the plan views and [sic] well as cross section information that has been provided. Please provide a discussion, and drawings as may be needed, that addresses all activities along the established Floodway Line. This information should address all aspects of all operations along this line through the completion of reclamation activities. Be sure to address best management practices, and any proposed setbacks in the response to this request. (emphasis in original)3/ Mr. Price described the proposed project as part of the permit application which was submitted to the Department: Describe in general terms the proposed project, system, or activity. Angelo's Aggregate Materials, Ltd. (AAM) owns approximately 341 acres of land. The current mining site, known as the Jasper Pit, is located on a 160 acre parcel of land. Of the 160 acres, only 82.45 acres are available for mining since the remainder of the property falls within the floodway boundary of the Alapaha River. The 160 acre parcel has an existing berm around the entire perimeter of the property constructed in the 1950's by the previous owner. The Alapaha flood study conducted for FEMA did not take into account this berm. AAM is proposing to construct a 20' wide access road between NW 8th Boulevard and the Jasper Pit, encompassing approximately 7.22 acres. This roadway will be constructed within the limits of property owned by AAM. The stormwater management system for the roadway will consist entirely of grassed swales as covered under FDEP's swale exemption. The Jasper Pit is a sand and limestone mining operation. (emphasis supplied) On August 28, 2001, David Still, the District's Director of Resource Management, wrote a letter to the Department in response to a request received by e-mail from the Department for technical assistance. Mr. Still responds to requests for technical assistance from other agencies as a matter of routine and as contemplated by the operating agreement between the Department and the District. The letter reads as follows: The floodway along the Alapaha River was identified and mapped as part of a Federal Emergency Management Association (FEMA) flood study performed by the United States Army Corps of Engineers, subsequently approved by FEMA and adopted as part of the local government (Hamilton County) ordinance. Based on the above, Suwannee River Water Management District (SRWMD) then adopted the floodway as a Work of the District (WOD). There is only one floodway. SRWMD recognizes and accepts the FEMA flood study performed by the U.S. Army Corps of Engineers and local government (Hamilton County) floodway boundary as the best available information to identify the floodway boundary. There is a formal process whereby change can be made to the FEMA boundary with additional or improved information. If FEMA and Hamilton County approve a revised floodway delineation and boundary, so be it, SRWMD will recognize it, however, SRWMD will not unilaterally change a boundary resulting from a detailed federal flood insurance study. We have informed Mr. Thompson and his client of this. We consider the kind of work contemplated by the applicant (at least based on our earliest discussions with them) will cause an adverse impact to the WOD (the floodway) which of course is in conflict with the requirements of 40B-400.103(1)(h) and SRWMD 40B-4, Part III, Florida Administrative Code (F.A.C.). The District will object to the issuance of any permit in direct conflict with District rules. We feel the rule is clear and any conflict with 40B-400.103(1)(h), F.A.C. which the Florida Department of Environmental Protection has adopted by reference requires denial of the Environmental Resource Permit (ERP) application. Any work of this nature within a WOD is subject to the additional permitting requirements of 40B-4, Part III, F.A.C., even if the District needs to implement such requirements with a separate WOD permit. Mr. Still's reference to "the applicant" in the August 28, 2001, letter is to Petitioner. While Mr. Still is not the agency head, his August 28, 2001, letter clearly communicates the District's policy. Given his position in the agency and the manner in which he discussed this issue, the letter describes and communicates the District's policy on what constitutes a floodway and its boundary. Mr. Still does not have final authority to make decisions on permitting within the District, as that authority rests with the governing board. In a letter written on October 10, 2001, in response to a letter from Petitioner's counsel, Mr. Still stated that District staff would recommend to their governing board that Petitioner's proposed activity is an activity within a floodway that is regulated under Chapter 40B-4, Part III, Florida Administrative Code, and that the proposed activity would adversely impact the floodway: "Therefore, as staff, we would recommend our governing board consider this activity adverse to our rules." This letter is case specific to Petitioner. Within a few days of Mr. Still's October 10, 2001, letter, Petitioner filed its Petition to Determine Validity of Agency Statements Defined as Rules. Other facts established by the evidence of record The District uses FEMA FIRM maps as evidence of the location of the floodways in the works of the district. The District communicated this policy in Mr. Still's letter dated August 28, 2001. The District will not unilaterally change the floodway delineation and boundary established by FEMA. In order for an applicant to persuade the District that a proposed activity within the FEMA floodway line is not within the District's floodway, an applicant must apply to FEMA for a map amendment or revision. The District will acknowledge that a proposed activity is not within the floodway of a work of the district only if the applicant is successful in obtaining a map amendment or revision showing that the proposed activity indeed is not within the floodway. The District has applied this policy to another company which applied for a permit. That is, the District required the permit applicant to apply to FEMA for a map revision or amendment as a condition of issuance of a permit because its proposed activity was within the FEMA floodway as established by the FEMA maps. Petitioner has not filed a permit application with the District regarding the proposed mining project. It is Petitioner's position that to do so would be futile.
The Issue Is Respondent responsible for alterations to a dam over which Petitioner has jurisdiction? Has Respondent performed these alterations without the benefit of a permit issued by Petitioner? Should Respondent be required to make changes to that structure?
Findings Of Fact One and one-half miles east of Crestview, Florida, which is in Okaloosa County, a dam has been constructed. The dam construction has formed an impoundment area thereby altering the course of a tributary to the Shoal River, an Outstanding Florida Water Body. Respondent contributed to the construction which formed the dam. He did so without benefit of a permit from Petitioner. No other person has obtained a permit from Petitioner for the dam construction. Respondent is a resident of Crestview, Florida. At present the impoundment of water created by the dam is more that 10 feet but less than 25 feet in height from the natural bed of the water course at the down stream tow of the barrier formed by the dam. The work which has been done on the dam by the Respondent is based upon his belief that he is entitled to an easement at the stream crossing. The dam impoundment has no agricultural purpose. John Rittenour claims ownership of the land at the stream crossing and takes issue with Respondent's belief that Respondent has an easement for that crossing. Mr. Rittenour did not authorize Respondent to do the work at the subject site nor was Mr. Rittenour responsible for performing work at the subject site independent of Respondent's activities. There is no dispute concerning Respondent's ownership of property in the vicinity of the stream crossing. Prior to March, 1990, Respondent had made certain changes at the subject site to maintain a vehicular crossing. The pre-March, 1990 changes were to a structure which used a culvert to allow the water in the stream to flow through the crossing. In addition Respondent was trying to create a water impoundment area behind that structure prior to March 1990. The nature of these activities was not such that the Petitioner had a basis for imposing the regulatory requirement that Respondent obtain a permit to conduct the alterations at the subject site. In March, 1990, the dam at the subject site breached. As a consequence, other structures down stream also failed. Those structures belonged to Mr. Rittenour. The breach created conditions unsafe to the public. In April, 1990, following the breach, Respondent reestablished the stream crossing. The work which he did created the present dam height which had been described. The stream crossing provides local residents with access to their homes. There is another route to those homes, but its future availability is in question. On July 30, 1993, Jerry Sheppard, Senior Field Representative for Petitioner, inspected the subject site. The findings that he made at that time are set forth in Petitioner's Exhibit No. 3. That Exhibit roughly describes the structure in question. In particular, it references the fact that the dam height is approximately 10.5 feet as observed through the form of measurement already described. The dam is 13 to 15 feet in depth. It's width is approximately 200 feet. It has horizontal culvert pipes to allow water flow through the dam. One pipe is 18 inches in circumference. The other pipe is 36 inches in circumference. The inspection which Mr. Sheppard made on July 30, 1993, revealed that the changes to the structure following the breach in March, 1990, had increased the water impoundment area as to the landward extent of that water. Mr. Sheppard was concerned with safety problems associated with the dam which he observed on July 30, 1993. He found the overall construction to be of poor quality. There were problems with vertical slopes on the dam faces, trees were observed to be on the slopes and the aggregate material used for construction was sandy in composition. All these conditions contributed to the substandard construction. Mr. Sheppard was also concerned about a change in the surface water volume that was created with the increase in the impoundment area. This could cause greater safety hazards in a future dam breach than had been occasioned by the March 1990 breach. The March experience released a lesser volume of water by comparison to the expected volume of water with a future breach. Lance Laird, P.E., had accompanied Mr. Sheppard on the inspection at the subject site that was conducted on July 30, 1993. Mr. Laird is an expert in agricultural engineering and design of small dams. Mr. Laird is employed by Petitioner and was in its employ in 1993. Mr. Laird's observations concerning the dam that were made on July 30, 1993 are memorialized in a document which Mr. Laird prepared on August 2, 1993. That document is Petitioner's Exhibit No. 5. Pertinent to this case, Mr. Laird notes that the method of establishing the dam height was done by shooting the dam centerline at 50 foot intervals and the elevation of the tow by examining the elevation of the normal ground at station 1+75. Specifically, the dam crest was found to be at a height of 10.48 feet to 11.04 feet. Therefore, it was established that the maximum impounding capacity would be at 11.04 feet of dam height. On September 7, 1993, Mr. Sheppard spoke with the Respondent. Respondent told Mr. Sheppard that the Respondent had an easement across the stream to allow access to property away from the stream. For that reason, Respondent told Mr. Sheppard that Respondent believed he could make alterations or repairs to the structure at the stream crossing that would be acceptable. Respondent also told Mr. Sheppard that the stream crossing structure was there before Respondent purchased property in the area and that Respondent had been responsible for making the repairs which are under consideration in this case. On this occasion Respondent told Mr. Sheppard that there were three or four mobile homes further down the lane from the stream crossing, in addition to one house site located in the area of the stream crossing. Respondent's Exhibit No. 4 is a memorandum concerning the telephone conversation which was conducted between Mr. Sheppard and the Respondent on September 7, 1993. As described in the August 2, 1993 memorandum which reflected the findings on July 30, 1993, the road crossing was over a dam found at the perennial stream which goes under the roadway formed by the dam. As Mr. Laird observed, the effect of the two culverts is to back the water up to within 3 feet of the dam crest. A plywood stop-log is placed over the entrance of the 36 inch pipe that serves as a principal spillway. There is a plywood plug for the inch pipe; however, it was not installed on July 30, 1993. On that date Messrs. Sheppard and Laird noted a washed out area that serves as the emergency spillway that was approximately 20 inches wide. When Mr. Laird made his inspection on July 30, 1993, he was of the opinion that the dam would not meet current engineering standards for construction of an earthen impoundment dam. In particular, he believed that the utilization of horizontal pipes and the history of failure of the structure were indications that the dam did not have the hydraulic capacity to meet the design storms that are anticipated for this area. The location of the 36 inch pipe was such that it was canterlevered out from the road fill by about 5 feet. The side slopes were from steep to vertical on the back slope. The upstream slopes were not found to be as steep. In the August 2, 1993 report Mr. Laird expressed the opinion that the facility/dam needed to be modified to meet hydrological/hydraulic requirements and other construction standards for dams used as access roads. Mr. Laird specifically noted that a further dam breach would have adverse affect on Mr. Rittenour's property, and ponds which were down stream and possibly cause the failure of structures that Mr. Rittenour had put in place, all leading to the possibility of the release of sediments into the Shoal River. On November 3, 1994, Mr. Laird returned to the subject site for further inspection. He rendered a report of that inspection on November 4, 1994. That report is found as Petitioner's Exhibit No. 7. In the course of the November 3, 1994 inspection Mr. Laird observed that the appearance of the dam was similar to that on July 30, 1993. The principal difference was that logs and debris were now present in the inlet and outlet ends of both of the culverts/pipes. Some of the logs were fairly large. One log was estimated to be 12 to 14 inches in diameter and 20 to 25 feet long. This log was at the outfall of the 36 inch pipe. The consequence of this debris in the areas of the two pipes was to restrict the hydraulic capacity of the system. This was made more significant because the horizontal pipes had inherent limitations on their hydraulic capacity. Under the circumstances it was imperative that the debris be removed. On this visit Mr. Laird also noted that the pipes were uncoated and rusting, thus limiting their life span. On this visit Mr. Laird noted that the emergency spillway had now become filled with sediments that had eroded from the road leading down the hillside to the dam site. Mr. Laird expressed a concern about the method of construction and the material used in that construction and the susceptibility of those fill materials to erode. In particular, Mr. Laird observed that the material was sandy and for that reason susceptible to erosion. Finally, Mr. Laird noted upon this visit that the sizing of the culverts had not been proven to be adequate when considering their intended function in the dam. On November 15, 1993, Messrs. Morgan, Laird, Sheppard and Mitchell May met with the Respondent and his attorney at the subject site. The outcome of that meeting is memorialized in the memorandum from Mr. Morgan dated November 16, 1993, a copy of which is Petitioner's Exhibit No. 2 admitted into evidence. In the November 15, 1993 meeting, Respondent and his attorney were told about the various concerns which the Petitioner had about this dam consistent with the prior observations made by Petitioner's staff as described in this recommended order. Discussions were held concerning the means of correcting the problems. At this time Respondent indicated that he had been informed, by someone who was not identified, that the alternate route for residents in the area to gain access to their homes was being closed and that the stream crossing would then form the only means of ingress and egress to those properties. Respondent explained that he had spent $3,000 in improving the dam. Further he made mention that he had originally sold 12.5 acres of property around the impoundment created by the dam and no longer had any interest in the property. Although no resolution was reached concerning the proper disposition of the problem created by the dam, Mr. Morgan noted in his November 16, 1993 memorandum that this safety hazard that had resulted from the impoundment of water at the dam site by virtue of the deficiencies in the dam construction must be corrected if the crossing was to be used as the sole access route into the residences which have been described. On November 19, 1993, Mr. Laird prepared a memorandum in response to the request by Respondent's counsel through correspondence dated November 8, 1993, concerning the method of establishing Petitioner's jurisdiction over the dam pursuant to the dam height. The November 19, 1993 memorandum coincides with prior observations about the method to be employed in establishing that jurisdiction which are set forth in this recommended order. A copy of the memorandum is Petitioner's Exhibit No. 6. Petitioner's Exhibit No. 6 has a rough sketch and other calculations in support of the determination of the dam height. Concerning Mr. Laird's testimony at hearing, he reiterated that the establishment of the dam height was through a measurement of the down stream site in which the elevation difference between the impounded water and down stream elevation at the stream bed were critical factors in determining the potential hazard should there be a further breach of the dam. As established by Mr. Laird, proper methods of dam construction must be carried out in accordance with accepted engineering practices. In trying to determine acceptable engineering practices Mr. Laird relies on his experience as a professional engineer and expert in the design of small dams together a number of publications, to include publications from the Soil Conservation Services on design of dams, the U.S. Corps of Engineers and the Bureau of Land Reclamation. As Mr. Laird described at hearing, the dam design is deficient in that it is not made of suitable materials. Those materials are sandy. This allows water to migrate through the dam and to saturate the dam, thereby making the dam more prone to failure. The slopes on the back side of the dame are so steep that they cannot be maintained. The dam is eroding and two gullies have formed extending up to the crest of the dam. There is a third pipe in the dam face which is 18 inches in diameter and it is rusting. This pipe was there before the dam breach in March, 1990. It was left in place when repairs were made following that breach. Its existence could increase the flow of water in the event of a failure of the dam or if this third pipe collapsed it could form a void in the dam face. The principal spillway for the present dam is created by the use of the newer pipes that were placed horizontally. The placement of those two pipes creates limited capacity for flow-through and their rusty condition creates limitations on the effective life of those pipes. Those pipes could not be relied upon to handle storm events. In anticipation of a storm event, the pipes are placed so high on the dam face that they could not be used to evacuate water to meet the contingency of an upcoming storm or flood event. This arrangement unlike a head gate or control device below the water surface, which would allow the evacuation of water to meet the upcoming contingency of a storm or flood event, is without utility. The placement of the present pipes at the dam site is so high that they cannot be relied upon to dewater in anticipation of such a contingency. As has been verified by observations of these pipes, horizontal pipes are prone to be clogged by debris. An appropriate spillway would have a means of protecting the spillway against clogging. The emergency spillway is inadequate in that it continues to be filled in from erosion of the hill above the emergency spillway. On the dam surface, trees, weeds and other debris make it difficult for someone to perform an inspection of the dam condition, which is a necessary activity. Those same materials can penetrate the dam surface and cause erosion or in some instances if a tree were to fall and break the surface of the dam could cause further erosion. In summary, the dam does not meet generally accepted engineering standards for design nor comply with the requirements of safety for small dams as established by the opinion of Mr. Laird. The dam poses a safety hazard to people using the dam to cross the stream and for the down stream landowners should the dam breach as it did in March 1990. Mr. Rittenour would not be opposed to having a stream crossing at the subject site to allow access to nearby properties. He is opposed to a dam at the site with its associated impoundment. Under the circumstances the appropriate means of addressing the problem of the dam would be to remove the dam and its associated impoundment of water and replace that structure with a crossing which would allow vehicular traffic. This disposition is consistent with the order for corrective action. This would involve the safe removal of water behind the present dam structure and reduce the risk of sudden release of an increased volume of water from a future breach when contrasted to the 1990 breach. In this solution the spillway pipes would be lowered to an elevation at the natural level of the stream, thus the impoundment would be ended with the new structure which would allow vehicular traffic to cross the stream. A one to two foot fill would need to be placed over the pipes to maintain the crossing as a roadway. This would lower the crest of the structure to an elevation just above the stream bed. During the course of any construction, sediment barriers would need to be placed downstream and in areas where the construction was ongoing to prevent problems with sedimentation. Grass would need to be placed on any disturbed areas and on the slopes of the new structure. Alternatively, the entire structure could be removed with proper controls being placed to protect against sedimentation and erosion in the area in question. Maintenance of the structure as a dam with its associated impoundment is not contemplated by this administrative action and would only be appropriate in the event that the dispute over the ownership of this site is resolved by informal settlement between Respondent and Mr. Rittenour or through litigation.
Recommendation Based upon consideration of the facts found and the conclusions of law reached, it is, RECOMMENDED: That a final order be entered which declares the dam and impoundment to be a public nuisance created by Respondent and informs the Respondent of the necessity to obtain a permit before removing the dam and impoundment and reestablishing the roadway at stream bed level.
