Findings Of Fact Background On January 29, 1981 respondent/applicant, George H. Hodges, Jr. (applicant or Hodges), filed application number 16 39644 with respondent, Department of Environmenta1 Regulation_ (DER), seeking a dredge and fill permit to generally authorize the excavation of 26,000 cubic yards of material from a 3,700 foot portion of an existing channel (Old Pablo Creek) just west of the Intracoastal Waterway (ICW) in Jacksonville, Florida. The channel then proposed was a straight channel along the northern boundary of his property. Hodges also sought to construct two boat slips, three floating docks, an 850 foot vertical bulkhead adjacent to the docks, and to dispose of all dredged material in a diked upland site. Thereafter, DER informally advised applicant that it intended to deny the application for various reasons, including the fact that the dredging would eliminate .75 acres of marsh and wetlands. After receiving this advice, Hodges proposed a series of amendments to his application in 1984 and 1985 in an effort to counter and satisfy DER's objections. The final amendment was made on September 10, 1985. As finally amended, Hodges proposed to confine all dredging to existing salt channels, thereby eliminating the objection that adjacent marshes would be destroyed. Applicant also proposed to restrict his dredging to only 2,250 feet along the northern portion of Old Pablo Creek and to remove 29,250 cubic yards of fill (silt) and sand and place the same in a 12.5 acre upland spoil site. By proposed agency action issued on February 28, 1985, DER announced it intended to issue the requested permit. This prompted a protest and request for hearing from petitioner, Jacksonville Shipyards, Inc. (JSI), which owns and operates a ship repair facility on the ICW just south of the proposed project. In its petition, JSI generally alleged that (a) Hodges had failed to give reasonable assurances that water quality standards would not be violated, (b) the project would adversely affect its property, (c) the project would have an adverse effect on the conservation of fish and wildlife, (d) the project would cause harmful erosion or shoaling, (e) DER failed to consider the long-term effect of the project on marine productivity and the cumulative impact of the project, and (f) the proposed vertical bulkhead did not meet statutory requirements. The Project The project site is a shallow horseshoe shaped creek approximately 3,700 feet in length which meanders through a vegetated salt marsh just west of the ICW in Duval County, Florida. Both ends of the creek connect into the ICW. The site is approximately one-half mile north of the bridge on Atlantic Boulevard which crosses the ICW. The ICW is a man-made channel constructed by the U. S. Corps of Engineers which runs in a north-south direction just east of the project site. It is commonly referred to as Pablo Creek. The channel or creek in which the dredging will occur is known as Old Pablo Creek (creek). An excellent aerial view of the entire area is shown in petitioner's exhibit 4 received in evidence. The creek is a predominately marine water classified as a Class III water of the State. Accordingly, it is subject to DER's regulatory jurisdiction. For purposes of this hearing, the parties have referred to the upper and lower portions of the creek as the northern and southern portions, respectively. Hodges intends to dredge the northern portion of the creek, which measures approximately 2250 feet in length from the ICW to a bend at its western end which crosses Hodges' property and where a residential site is located. According to Hodge's affidavit of ownership, he is the "fee interest owner of adjoining lands except for the dredge channel which is owned by the State of Florida". He acknowledged, however, that the residential site is owned by his superintendent, and that the marshes adjoining the most southern bend in the northern portion of the creek, and the southern portion of the creek, are owned by JSI. Except for the cleared residential site at its western end, the creek is surrounded by vegetation and salt marshes. The vegetated portion of the marsh is marked by a clearly delineated edge which separates it from the creek bottom. The dominant species of vegetation in the marsh are Juncus and Spartina. The marsh serves as a habitat and breeding ground for numerous species, including fiddler crabs, mussels, barnacles, mollusks, faunal communities and gastropods. In addition, the marsh is beneficial because of its biotic productivity and entrapment of nutrients and sediments. For this reason, the habitat should be maintained. Some forty years ago, the portion of the creek that Hodges intends to dredge was eight to twelve feet deep. However, dredging of the ICW by the Corps of Engineers and the placement of fill at the site of the Atlantic Boulevard Bridge have contributed to the shallowing of the creek over time. Today, portions of the creek are exposed and impassable under low tide conditions. Indeed, many parts of the creek are dry during the low tide phase of the ICW. At high tide, the creek is flooded to an approximate depth of four feet. Hodges proposes to dredge the creek channel to a uniform depth of five feet below mean low water (MLW) with side slopes at a 3:1 ratio to restore navigational access from his upland property to the ICW. He has represented that his use of the channel will be restricted to one, or possibly two, small boats for personal use and enjoyment. When completed, the creek channel will have a depth of nine feet at high tide, or an average depth of seven feet over a diurnal cycle. In his amended application, Hodges proposed to confine his dredging to existing creek channels, and to not disturb the actual body of the salt marsh or the vegetation bordering the creek. It is noted that there is no vegetation growing in the existing creek bottom. However, at hearing he conceded that dredging "may include some minor removal of isolated patches of grass growing in the creek channel". One such patch of grass lies in the elbow of the canal which reaches south of Hodges' property, a patch separated from the main body of the marsh by a five foot wide slough deep enough to be navigated at high tide. Hodges estimates this patch of grass to be less than 1/100 of an acre in size (10' x 40') and maintains the effect of its removal would be negligible. The excavation will be effected by means of a Mud Cat hydraulic dredge which operates by suctioning the sediment and water into a pipe. The dredge material (sediment/water mixture) will then be pumped into a series of containment cells on a 12.5 acre upland spoil site that lies approximately one-half mile northeast of the project. Any discharge from the spoil site will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. The natural grade of the existing creek bottom is at or below the mean low water datum. At high tide the existing creek is 4.3 feet deep at its deepest point and gradually slopes upward to a depth of 2.4 feet near the marsh. The elevation of the creek where it meets the marsh is close to mean high water. Even so, the channel width does not always correspond with the mean high water line boundaries of the creek, and creek waters sometimes inundate and extend back into the marsh at high tide. Because Old Pablo Creek is tidally influenced, any water quality violations in the northern portion of the creek can be expected to also have an adverse effect in the southern portion as well. Creek Width Petitioner has raised the issue of whether the creek is as wide as Hodges represents it to be on the drawings attached to the amended application. This is significant since (a) the engineering plans are based upon the assumption that the measurements in the application are correct, (b) the proposed dimensions (depth and side slopes) of the new channel are dependent upon the existing creek having a minimum width of from sixty to eighty feet, as represented by Hodges, and (c) any excavation outside of the existing channel will result in the removal (destruction) of vegetation and marsh. In his application, Hodges reflects the top width of the creek to be sixty to eighty feet, which width will enable him to dredge the channel to an average depth of five feet below MLW, and maintain a side slope ratio of 3:1. This ratio is necessary because of the composition of the sediment in the creek. The minimum top width required to excavate a channel with 3:1 side slopes to a depth of five feet below MLW is fifty- four feet. Petitioner's exhibit 4 identifies five points along the eastern half of the northern portion which have been measured by the parties to determine the actual width of the creek. Although only five points were measured, it may be inferred that these distances are representative of the creek's width throughout its eastern half. At points five through eight, the widths are forty-nine, thirty-five, fifty and fifty feet, respectively, which are less than the measurements contained in the application. If the channel is constructed with the minimum top width (54 feet) required to have 3:1 side slopes, it will result in the elimination of 6 feet of marsh at point 5, 19.5 feet of marsh at point 6, and 4.1 feet of marsh at both points 7 and 8. This equates to the elimination of approximately .33 acres of marsh. Since the above measurements are representative of the eastern half of the northern portion, other areas of vegetation, albeit in unknown proportions, would also have to eliminated. If, for example, applicant attempts to construct a channel within the confines of the portion of the creek that has a top width of only thirty-five feet (point 6), the maximum channel that could be constructed would be V-shaped with a depth of one foot at low tide. Assuming the remaining part of the channel was excavated to -5' MLW, a stagnant area would develop in this portion of the channel and adversely affect water quality. However, to counter the problem at point 6, Hodges intends to remove one patch of grass 10' by 40' in size to achieve the desired width. Any adverse effects on the adjacent marsh at that particular point would be negligible. Because the estimated creek width is not accurate, even the agency now concedes the engineering plans are no longer useful. As a condition to the issuance of a permit, DER has suggested that Hodges be required to submit new certified engineering drawings depicting the proposed cross-section of the channel. It also suggests that the proposed cross-section comply with the top-widths depicted in applicant's exhibit 53, and depict side-slopes of three to one. It further suggests that a condition for the issuance of any permit be a requirement that the 3:1 ratio be maintained, and that other than point 6, no other grass be removed. Finally, the agency proposes that if the new plans and conditions do not permit a -5 MLW depth, the proposed depth be reduced accordingly. However, the evidence supports a finding that either vegetation must be removed at various points along the eastern half of the creek in order to maintain a 3:1 ratio for side slopes, or the depth must be reduced. By reducing the depth at certain points, stagnant areas in the creek will develop, thereby adversely affecting the quality of the water. Further, as noted hereinafter, the validity of the flushing analysis performed by applicant's experts rests upon the assumption that a -5' MLW uniform depth will be used. Finally, the applicant has not given reasonable assurance that the marsh and habitat will not be adversely affected by the elimination of the vegetation which is necessary to achieve the desired depth and concomitant 3:1 ratio. Therefore, the alternative conditions suggested by DER are neither reasonable or appropriate. The Spoil Area The spoil area to be used by applicant is a 12.5 acre upland disposal site approximately one-half mile northeast of Hodges' property. Applicant does not own the upland spoil site but has obtained easements from the owner which expire in March, 1987. In other words, he must complete all work on the project by that date or lose access to the property. The proposed spoil site is completely diked, and is sectioned off into three sections by interior dikes with overflow pipes. Internal baffles and silt fences are also designed into the area. Uncontradicted testimony established that the spoil area is "unusually well designed". Any discharge from the spoil area will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. Discharge, if any, will be outfall from an overflow structure in the third section of the spoil area to a dump area land then by sheet flow to salt marshes adjacent to Greenfield Creek. The vegetation in Greenfield Creek consists of a salt marsh expanse of Spartina alterniTlora and Juncus roemerianus. Both species survive in and are indicative of regular introduction of saline waters, and show high tolerance to varying salinity levels. If saline waters from Old Pablo Creek were introduced into Greenfield Creek, it would have no adverse impact on the Greenfield Creek ecosystem. The size of the site was originally designed for a project of 100,000 cubic yards. The site will retain all |effluent from the dredging. The expected total effluent, both sediment and water, is roughly 5.3 million cubic feet of material, assuming a ratio of 6.7 cubic feet of water for each |cubic foot of sediment dredged. This is slightly lower than the 5.4 million cubic feet total capacity of the site. The supernatant from the discharge being deposited into the first cell of the spoil area will only flow into the next cell when the first cell fills and the level of the supernatant rises above the top of the vertical drain pipe overflow structure. If rainfall events cause the cells to fill with water during dredging and discharge operations, the discharge to the next cell or to Greenfield Creek will be primarily fresh water. This will occur because introduction of fresh rainwater into the brackish water from the dredge area will cause stratification, and the fresh rainwater will form a layer on top that will flow into the overflow structure. Turbidity Effects In removing the mud bottom from the creek to a depth of -5' MLW, some turbidity will occur. This is a natural by- product of using the hydraulic dredge. However, the amount of turbidity, and its effect on the waters at the dredge site and discharge point, are in issue. State water quality standards prohibit the discharge of water with a turbidity level greater than twenty-nine nephelometric units (NTU's) above the background levels of the receiving waters. The evidence indicates that the background turbidity levels at the creek are now in the range of ten to twenty NTV's. Excessive levels can result in adverse effects on local biota such as decreasing productivity by reducing light penetration. Excessive turbidity can also be expected to suffocate organisms. The area to be dredged contains sediment deposited from the surrounding salt marsh and carried in from the ICW. The sediment is composed of 14% clay, with the remainder being sand and silt. This was confirmed by a laboratory analysis conducted by JSI. As a general rule, the coarser the material, the faster it tends to settle out thereby creating less turbidity problems. Therefore, sand, which is of a grain size, can be expected to settle out quickly while silt takes somewhat longer. However, clay size particles are much smaller than silt and do not settle out as easily. Applicant made no laboratory analysis of sediment and consequently he erroneously assumed the mud to be sand and silt, and did not take the clay particles into account. The dredging in the creek will cause the turbidity levels to rise to 150 NTU's. However, the placement of a turbidity screen at the entrance to the ICW will prevent the release of this turbidity into that water body. Therefore, if a permit is issued, such screens should be used by Hodges at the dredge site. At the spoil site, clay size particles will also be included in the matter pumped for discharge. If these particles do not settle out, or are not treated, their discharge into Greenfield Creek (a jurisdictional water) will cause violations of the turbidity standards. To counter their effects, flocculants (chemicals) should be added when necessary to the confined material to aid the particles in settling. If a permit is issued, this should be made a condition in the permit. Dissolved Oxygen Impacts The dissolved oxygen (DO) levels in the creek fluctuate on a daily and seasonal basis. As a general rule, DO levels tend to be lower in warmer weather and during the early morning hours. Therefore, a "worst case" situation will generally occur in the summer months in the early part of the day. State water quality standards contained in Rule 17- 3.121(13), F.A.C., provide that in predominately marine waters, the concentrations of DO "shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter." Sampling conducted by petitioner at 5:00 a.m. in early July, 1986 during high tide revealed readings ranging from 3.06 mg/1 in the western portion of the creek to 4.59 mg/1 at the mouth of the creek. Dissolved oxygen levels in the ICW ranged from 3.94 to 4.68 mg/1. Hodges also sampled the creek and ICW in the late morning or early afternoon on August 6,1986 and determined DO levels to be 4.8 mg/1 in the creek and 5.8 mg/1 in the ICW. Testing at that hour of the day produced higher values than those found by JSI. The readings collectively confirm that DO levels in the creek are approximately 1.0 mg/1 less than the DO levels in the ICW. This deficit is primarily caused by the high oxygen demand exerted by the adjacent marsh and muds in the creek. This situation will not be changed by the dredging. The flushing time of the creek channel is an important factor in predicting post-dredging impacts on water quality. Flushing time determines how rapidly waters of the ICW will exchange and mix with the water in the creek channel. Both Hodges and JSI conducted tidal prism studies to determine how many tidal cycles would be required to flush a hypothetical pollutant to 10% of its initial concentration. Under worst case conditions, the channel is expected after dredging to flush every 3 to 4 tidal cycles or 1.6 days. Under more favorable conditions, the creek is expected to flush every 2 to 3 tidal cycles. This compares with the current system which flushes almost 100% every tidal cycle or once every twelve hours. The increased flushing time is due to the significantly greater volume of water that will enter the creek channel after dredging. Because of increased channel depths, the water will move at a slower velocity. Therefore, the oxygen consuming components have a longer period of time to react in the water column. This in turn will cause reductions in DO levels of between .7 mg/l and 1.5 mg/l in the creek. This was confirmed through tidal prism modeling performed by JSI. In this regard, it is noted that JSI's modeling was more sophisticated, better calibrated, and its assumptions were more accurate and reasonable. Consequently, its testing results are considered to be more reliable and persuasive than that of applicant. It must also be recognized that the deepening of those areas that are currently exposed at low tide will allow water to move more easily through the channel and remove some oxygen demanding sediments that now draw from a shallow water column. This will tend to have a beneficial effect on water quality. However, the overall impact of these beneficial effects is unknown, and it was not demonstrated that the otherwise adverse effect on DO will be offset or minimized by the unmeasured impact of deepening the shallow areas. Therefore, applicant has not given reasonable assurance that water quality standards will not be violated by the project. At the same time, it must be further noted that a reduction in the channel depth due to the smaller width of the creek will alter the results of the tidal prism studies, as well as negate some of the beneficial effects caused by deepening the shallow portions of the channel. To what extent the studies are changed, or benefits will be reduced, is not of record. Other Effects of Project As noted earlier, Hodges intends to use one or two boats on the deepened channel. The use of the boats will not introduce pollutants in any significant quantity. Hodges proposes to construct his docks and place rip- rap on the northern side of the widest portion of the creek channel. Little, if any, vegetation will be eliminated by these activities. The use of rip-rap for the construction of the bulkhead is the most environmentally sound means of bulkheading, and will stabilize the shoreline as well as provide habitat for aquatic organisms. The dredging of the creek channel will improve the navigability of the creek, and permit the use of boats in areas where access is now impossible under low-tide conditions. In addition, the sharp bends in the creek will prevent the operation of boats at high speeds. JSI's concern that boats may run aground once they leave the northern portion and enter the southern portion is not meritorious since few, if any, are expected to use the latter part of the creek, and the sharp bends will force boaters to operate at low speeds. Shoaling or erosion of the southern portion will not result from the proposed activities. Indeed, an increased flushing and introduction of new flow into the system may benefit the northern portion. Any situation occurring in that part of the creek should not exceed the rate of siltation occurring under current conditions. The benthic organisms which populate the bottom of Old Pablo Creek include crabs, mussels, barnacles and other species normally associated with estuarine systems. The removal of the mud bottom in the dredging operation may remove some of these organisms. However, this should not significantly change the habitat of these benthic organisms. Rapid recolonization by these species would be expected with recolonization substantially underway within forty-eight hours
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 16-39644 of George H. Hodges, Jr. for a dredge and fill permit be DENIED. DONE and ORDERED this 2nd day of December, 1986 in Tallahassee, Florida. DONALD R. ALEXANDER, Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 2nd day of December, 1986.
Findings Of Fact By application dated August 28, 1984, Petitioner sought a permit from Respondent to deepen an existing ditch on his property from a current depth of one and a half feet to a proposed depth of three feet. The ditch is eight feet wide and eight hundred and fifty feet long and extends through a wetlands area to Lake Tohopekaliga which has been classified as a Class III waterbody. Petitioner intends to dredge approximately 377 cubic yards of material waterward of the ordinary high water elevation in order to make the existing storm drainage ditch navigable. This application was received by Respondent on September 11, 1984, and was accepted as complete on November 6, 1984. On January 9, 1985, an on-site inspection was concluded by Barbara Bess supervisor of dredge and fill permitting in Respondent's Orlando district office, who thereafter prepared an appraisal report dated January 23, 1985. As expressed in her report, Bess' primary concern with this application was the potential loss of fish and wildlife habitat which would result from the loss of grasses and macro-invertebrates resulting from the proposed project. Lake Tohopekaliga is a very popular and productive sportfishing lake, and the cumulative effect of such dredging activity, if it occurred around the lake would have a severely negative impact on the lake's food chain. This would in turn have adverse consequences for sportfishing and the water quality of the lake. Since similar drainage ditches do exist around the entire lake, there is a reasonable likelihood of similar projects occurring if this one is approved. Petitioner proposes that his dredging take place during a draw-down of Lake Tohopekaliga which has already been planned, and contends that the negative impact of the proposed deepening will be minimized since the ditch will be substantially dry during the draw-down. Petitioner's contention, however, is not supported by the evidence. Testimony from Barbara Bess, who was accepted as an expert on water quality standards and the biological impact of construction projects on water quality, and testimony from Ed Moyer, fisheries biologist with the Game and Fresh Water Fish Commission, established that Petitioner's ditch may not be completely dry during the draw-down, and that the proposed deepening will increase boat traffic due to the ditch's navigability, thereby reducing vegetation and harming the food chain in the immediate area of the ditch. The cumulative effect of similar projects occurring, even during the draw-down, will be negative for sportfishing and the water quality of the lake. Respondent issued its Intent to Deny on January 25,1985, in response to which Petitioner timely sought a hearing. The parties were allowed to submit proposed findings of fact and conclusions of law pursuant to Section 120.57(1)(b)4, F.S. A ruling on each proposed finding has been made either directly or indirectly in this Recommended Order, except where such proposed findings of fact have been rejected as subordinate, cumulative, immaterial, or unnecessary.
Recommendation Based on the foregoing, it is recommended that Respondent enter a Final Order denying Petitioner's permit application. DONE and ENTERED this 23rd day of May, 1985, at Tallahassee, Florida. DONALD D.

Findings Of Fact This hearing was occasioned by the Respondent's denial of (an) environmental permit(s) requested by the Petitioner, Baker Cut Point Company, a corporation owned by James C. Dougherty. The Respondent has asserted permit jurisdiction pursuant to Chapters 253 and 403, Florida Statutes, and attending regulatory provisions of Chapter 17, Florida Administrative Code. The Petitioner requested a formal hearing to consider the matters in dispute, and that hearing was conducted on the dates indicated before and in keeping with Subsection 120.57(1), Florida Statutes. The Petitioner owns land in Monroe County, Florida, identified as Buccaneer Point. This parcel of land is a peninsula which extends from the west side of Key Largo, Florida, and has as its essential features two interior lakes and well-defined mangrove stands to include red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinans). This parcel of land is bordered on the north by Buttonwood Sound and on the south by Florida Bay, navigable water bodies. Respondent's Exhibit No. 1, admitted into evidence, depicts the present condition of the parcel of land, with the exception of proposals involved in the permit review process, which are the subject of this Recommended Order and the companion case of James C. Dougherty v. State of Florida, Department of Environmental Regulation, DOAH Case No. 80-1055. At present, the two lakes do not offer normal access to Buttonwood Sound and Florida Bay, nor do they offer an interior water connection between the two lakes. The southernmost lake does have intermittent water exchange with Florida Bay. Those lakes are identified as North Lake and South Lake. The Petitioner had initially applied for permission to place 75,000 cubic yards of clean limerock fill at the project site and indicated that the fill would be placed landward of the mean high water line. That fill would have covered approximately 17.56 acres in the residential subdivision. The application was made on October 27, 1978. See Petitioner's Exhibit No. 20, admitted into evidence. The Respondent issued an Intent to Deny the permit connected with that request, and that Intent to Deny was issued on April 3, 1980, asserting permit jurisdiction by the Respondent under the provisions of Chapters 253 and 403, Florida Statutes. See Petitioner's Exhibit No. 5, admitted into evidence. The Petitioner modified the permit application effective April 24, 1981. Under the terms of the revised permit application, the Petitioner would place limerock fill over 5.7 acres, including mangroves, constituting approximately 30,000 cubic yards of fill. Additionally, the applicant modified the permit request to include filling the exterior rim of the interior lakes to create a littoral zone and the placement of a berm at that exterior. See Petitioner's Exhibit No. 6, admitted into evidence. The project, as contemplated, allows for a preserve area of mangroves along the northern end of the peninsula and also employs a "pad" concept to preserve the mangrove acreage where fill is to be placed. Those "pads" for houses would be bordered by six- inch dikes to divert upland runoff which might find its way into the interior lakes on the property. The fill material to be placed in those areas, other than the lakes, would be placed above or landward of the line of mean high water, as determined by the mean high water line survey found in Petitioner's Exhibit No. 1, admitted into evidence, dating from December, 1975, and whose methodology was approved on January 15, 1980, for purposes of Chapter 177, Florida Statutes, through the offices of the State of Florida, Department of Natural Resources. This factual determination is also borne out by a review of the Petitioner's Exhibit No. 6, in pari materia with Respondent's Exhibit No. 1 and Petitioner's Exhibit No. 1. As the lakes are now constituted, the placement of the limerock fill at the fringe of the lakes would not be waterward of the line of mean high water; however, when the placement of this fill material is considered in view of the permit request made in Division of Administrative Hearings' Case No. 80-1055, which permit request attempts to open up the lakes by direct water connection to the aforementioned navigable water bodies, then the placement of the fill would be below the line of mean high water. See Petitioner's Exhibit No. 6. Therefore, treatment of the placement of fill for purposes of this case will be considered on a basis that the lakes remain landlocked and the matter of the placement of this fill will be a matter assumed in the Division of Administrative Hearings' Case No. 80-1055, dealing with an attempt to open those lakes by direct water connection to navigable waters of the State. Although the mangrove areas to be filled by the project are landward of the mean high water line, those mangroves are inundated by water at times and considered to be "submerged lands" adjacent to the State water bodies, Buttonwood Sound and Florida Bay. If the mangroves are removed, part of the ecosystem's ability to filter sediments and nutrients contained in stormwater runoff of adjacent upland areas and from tidal flows will be destroyed and will affect water quality considerations for adjacent open bay estuarine or marine systems. The extensive root system of the mangroves and associated vegetation assist in stabilization of estuarine shoreline sediments and attenuation of storm generated tides. Even though some of the mangroves in the proposed area for fill are in a stressed condition, i.e., a condition in which their growth is stunted, if left alone, those mangroves would flourish and provide the same water quality functions as healthy mangroves. A biologist presented by the Petitioner identified the number of mangrove species, the number of mangroves, the diameter of those mangroves and the height of canopies of the mangroves in areas of the project site. These items were summarized through the use of the Holdridge Complexity Index, which measures structural complexity of mangroves within the sites. See Petitioner's Exhibit No. 17, admitted into evidence. In particular, four such station pairs were studied and the pairs were constituted of a station within the basin of the mangrove stand and a station at the fringe of the mangroves. There was a site at each proposed waterway and a site at the northeastern and western points of the peninsula, the area of the proposed mangrove preserve. See Petitioner's Exhibit No. 6, admitted into evidence. This study indicated that fringe mangroves are more developed than the ones in the heart of the basins. This study also revealed that the upland fill would remove primarily black mangroves. The removal of the mangroves and placement of fill would be in furtherance of the creation of twelve to fourteen residential lots, the majority of which would be located on Florida Bay. See Petitioner's Exhibit No. 6. In furtherance of the intention to offer these lots for sale, the Petitioner has sold one of the lots on Florida Bay for $95,000 on or about June 2, 1981. If the proposed utilization of the property in question was not allowed, the Petitioner stands to lose money in his investment in the face of preliminary developmental expenses which, at present, exceed monetary returns from the sale of lots. The area in which the upland fill would be placed is porous limerock, which allows water to seep through and be transported underground to adjoining water bodies, both on site and off site, in addition to the runoff from the upland areas. To address these concerns, the Petitioner has planned for the installation of dikes in the various upland areas which are to be built to prohibit drainage into the remaining mangrove areas and ambient waters. The littoral zones around the edge of the inland lakes would promote marine and wetland vegetation which assists in the function of filtration of sediments and nutrients. On the subject of water quality considerations, the use of the clean limerock fill, which is calcium carbonate, would tend to stabilize seawater at its natural PH level, thereby allowing the specific conductance (measurement of salinity) of the lakes and surrounding ambient waters to remain in a natural state in terms of direct effects of the fill material. On the subject of contamination of water by copper, normally, seawater contains 3 micrograms per liter of copper. In a project such as this one, it is not expected that higher amounts of copper would be found, and the limerock contains only trace amounts of copper, if any. Specific testing done at the project site reveals less than 1 microgram per liter of copper in the North Lake and 4 micrograms per liter in the South Lake. Therefore, the activity is not expected to increase the levels of copper to the extent that measurements exceed 500 micrograms per liter in either the lakes or surrounding waters. In dealing with the substance of zinc, seawater contains as much as 30 micrograms per liter of zinc. Sampling by the Petitioner indicated 2 micrograms per liter in the North Lake and 8 micrograms per liter in the South Lake of that substance. The activity and the development is not expected to increase the levels of zinc to the extent that measurements exceed 1,000 micrograms per liter in either the lakes or surrounding waters. In sampling for lead content, the samples revealed less than 50 micrograms per liter of lead and the placement of limerock fill will not cause the amounts of lead in the lakes and surrounding waters to exceed 50 micrograms per liter. Testing for phenolic compounds at the site revealed that these materials were below established standards of the Respondent, and it is not expected that those standards will be exceeded through activities proposed in this permit process. The testing for oils and greases indicated less than 1 milligram per liter of oils and greases, which is below the State's standard of 15 milligrams per liter, and the activities proposed at the project site are not anticipated to exceed 15 milligrams per liter of oils and greases. Normal PH for coastal waters is 6 to 8.5, and the PH levels of the lakes and ambient waters in the area were in the range of 8, except for measurements done in the winter at the North Lake, where they were shown to be 7.5. The placement of limerock fill will not cause an imbalance in the pH readings. The activity as proposed will not add substances which are created by industrial or agricultural means or cause other discharges, colors or odors, or otherwise promote a nuisance condition in the ambient waters or the lakes. Measurement was made to toxic materials in the way of synthetics, organics or heavy metals. Those tests in the lakes and ambient waters showed heavy metals to be at low levels. There were no sources revealed of synthetics or organics. (The calcium carbonate found in the limerock fill would assist in breaking down lawn pesticides into phosphate.) In summary, the filling, as proposed, is not expected to promote the introduction of toxic substances into the lakes or surrounding waters. The placement of the clean limerock fill in the upland area is not expected to cause problems with turbidity in the lakes or ambient waters, which turbidity would exceed 50 Jackson Units above background. The filling will not affect dissolved, oxygen levels of the surrounding waters. Biochemical oxygen demand, the measurement of demand for oxygen of organic and chemical materials in the water, will not be influenced by the placement of the clean limerock fill related to surrounding waters. The limerock fill is not expected to introduce other oxygen demanding materials into the subject waters, such that dissolved oxygen levels would be lowered by BOD loading. There will be no problem with dissolved solids, in this instance, salts, due to the fact that calcium carbonate fill would not affect the dissolved solids in the ambient waters or in the lakes. Coastal water PH normally measures 6 to 8.5 and PH for open waters in the range of 1. Placement of calcium carbonate fill on the uplands would not cause the PH in the Class II waters in Everglades National Park, which is 300 feet east of Baker Cut Point, to vary above or below normal levels for either coastal or open waters. In addition, there would be no discharge of toxic substances from the calcium carbonate fill into the Class II waters herein described. Tests conducted in the vicinity of homesites utilizing septic tanks, and specifically as sampled in waters adjacent to Buccaneer Point and the subject lakes in a development known as Private Park and Buttonwood Sound , indicated less than one fecal coliform bacterium per 100 milliliters. See Petitioner's Exhibit No. 14, admitted into evidence. Anticipated setbacks for additional septic tanks to be associated with the buildup at the project site would be in keeping with the requirements of Monroe County, Florida, and harmful septic tank leachate is not expected to be a problem.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: On May 3, 1978, the petitioner filed with the respondent an application for dredge and fill permits and a water quality certificate to allow petitioner to complete its planned residential community on and adjacent to Marco Island, Florida. the petitioner expended in excess of $100,000.00 in preparing the permit application. The proposed project involves some 4,000 acres of development on approximately 17,000 acres of land owned by the petitioner. On November 28, 1979, after seeking and obtaining additional information from the petitioner, the respondent issued its notice of "intent to deny" the permit application. The Department claims jurisdiction over the proposed project pursuant to Chapter 253 and 403, Florida Statutes, and Section 17-4.28 and 17-4.29, Florida Administrative Code. The nine page "intent to deny" specifically cites Rule 1704.28(3), Florida Administrative Code, and concludes that state water quality standards will be violated. Beyond that regulatory citation, the "intent to deny" does not specify by rule number which of the water quality standards the Department feels would be violated by the proposed project. However, the "intent to deny" does conclude that the area proposed for development will include "approximately 1,500 acres of uplands and approximately 2,600 acres of waters of the State, submerged lands of waters of the State, and transition zone of submerged lands of waters of the State. In discussing the overall impact from the project as a whole, the respondent notes that the intertidal shoreline areas are utilized by wading birds and that the mangrove tidelines provide a vital habitat for fish and wildlife. In discussing the specific work areas, the respondent concludes that the destruction of the extensive freshwater marsh system would eliminate a significant habitat intensely utilized by a wide variety of birds. The "intent to deny" further concludes that the development of the proposed work area would be expected to violate state water quality standards for dissolved oxygen. The respondent's "intent to deny" is the subject of a pending administrative proceeding between these same parties in Case Numbers 79-2471 and 80-683. In those proceedings the petitioner is contesting, inter alia, the respondent's application of the rules under challenge in this proceeding. Although petitioner challenges other rules of the Department, the testimony adduced at the hearing concerned only those rules relating to water quality standards; to wit: Rules 17-3.05, 17-3.08(4) and 17-3.09(3). Dissolved oxygen concentrations are an important gauge of the existing quality of water and the ability of a water body to support a well-balanced aquatic animal life. A concentration of at least 5.0 parts per million (or milligrams per liter) is needed to support a well-balanced fish population, and a concentration of 4.0 mg/1 is about the lowest which will support a varied fish population. There are numerous natural factors which affect the concentration of dissolved oxygen in surface water bodies. Such factors include physical transfer between the water and the atmosphere (aeration), the limit of a water body's ability to absorb oxygen (saturation value), the amount of oxygen used to decompose dead material, photosynthesis of aquatic plants and the actual vertical location of the sampling. These factors are influenced by many variables, such as wind, temperature, stratification, salinity, the season of the year, the time of the day, rainfall, water clarity, mixing and flushing. The level of dissolved oxygen can vary significantly in the same body of water during one twenty-four hour period. A balance of dynamic, natural processes causes dissolved oxygen levels to vary extensively in different water bodies and within the same water body during different times of the day and during different seasons of the year. Some of the water bodies in the Marco Island area contain dissolved oxygen values below 4.0 parts per million (or milligrams per liter) during at least a portion of a twenty-four hour period. This is due to natural, as opposed to manmade, causes. A water body containing levels of dissolved oxygen less than 4.0 milligrams per liter does not necessarily indicate a discharge of contaminants into that water body. The parties have stipulated that the Final Order rendered by the Department of Environmental Regulation in the case of Capeletti Brothers, Inc. v. Dept. of Environmental Regulation, Case No. 79-1602R (July 7, 1980), accurately represents the Department's position with respect to its authority to consider wildlife and other biological factors in reviewing permit applications pursuant to Chapter 403, Florida Statutes.
Findings Of Fact On April 2, 1981, Lee County applied to DER for a permit to construct an extension of Colonial Boulevard east to State Road 82B by dredging 4,600 cubic yards of material landward of the ordinary high water mark, and by depositing 83,000 cubic yards of fill landward of the ordinary high water mark in an area of Lee County known as the Six Mile Cypress Strand or Six Mile Cypress Slough. The permit application was made by Lee County on standard DER forms which would have been appropriate for an application under either or both Chapters 253 or 403, Florida Statutes. Additionally, Lee County tendered a permit application fee to DER sufficient to cover the cost of an application under both statutes. After review of the application, DER determined that it had no jurisdiction under Chapter 253, Florida Statutes, and refunded to Lee County that portion of the permit application fee required for a Chapter 253 permit. As indicated above, Lee County's application, on its face, reflected that no fill material or dredging was proposed waterward of the ordinary high water mark. The Six Mile Cypress Strand is a meandering swamp, approximately 44,000 acres in size, dominated by cypress trees. At periods of high water the waters of the swamp empty into Ten Mile Canal, an artificial water body which connects to Estero Bay by way of Mullock Creek, a natural stream. All water bodies involved in this proceeding are classified as Class III waters. Six Mile Cypress Strand functions as a major aquifer recharge area for the eastern central portion of Lee County. The area drained by the Strand receives approximately 54 inches of rainfall annually. The wetland vegetation and uneven contours of the Strand allow the assimilation of nutrients and reduction in turbidity and erosion which could otherwise adversely affect downstream waters. The drainage area north of the proposed project consists of approximately 5,000 acres, or 11 percent of the total drainage basin served by the Strand. The proposed roadway would cross the Strand through a corridor which contains three cypress heads, or flag ponds. These ponds generally retain water during dry periods and support a more diverse community of aquatic life than those portions of the Strand which become completely dry. At the time of final hearing in this cause, these ponds exhibited dry season characteristics and contained less than one foot of water in their deepest portions. During low water periods the Strand itself may be virtually dry except for standing water in the vicinity of cypress heads and flag ponds. Only during the rainy season, which occurs during approximately four months of the year, does the Strand contain standing water. During high water periods, however, water may flow continuously throughout the length of the Strand. During these latter periods, canoes and other such small water craft may be able to negotiate portions of the Strand. No evidence was presented, however, which would indicate that the Strand is now or has ever been utilized, or is susceptible to utilization, for commercial boat traffic. The lands in the Strand over which Lee County proposes to build the roadway were conveyed by the Trustees of the Internal Improvement Trust Fund to private ownership after having been acquired from the federal government under the Swamp and Overflow Grant Act of 1850. The Strand was not meandered in the original government survey of the area, and, in fact, the surveyor's field notes reflect that the area of the Strand was densely vegetated and crossed by several roads, including one crossing the section line in the same vicinity proposed for the Colonial Boulevard extension. The existence of this last referenced road is corroborated by biological evidence presently existing on the site, and from examinations of full infrared aerial photography of the area. It is approximately nine miles from the Strand to the nearest meander line contained in the original government survey. Further, evidence of record in this proceeding establishes that water craft may not presently be navigated from Estero Bay into the Strand because of man-made barriers, and no record evidence establishes that such navigation would have been possible at the time of Florida's admission to statehood in 1845 when the stream presumably was in its natural condition. The Department of Natural Resources was notified in accordance with DER policy, of the pendency of Lee County's application, and asserted no claim of ownership over sovereignty lands in the area of the proposed project. The design for the proposed roadway includes a system of collector and spreader swales on the upstream and downstream sides of the Strand, respectively, connected by large culverts to be located beneath the roadway. The swales and culverts are intended to minimize interruption of the Strand's hydroperiod, the natural fluctuation and flow of waters within the affected portion of the Strand. A vegetated swale system paralleling the roadway is also included in the proposed roadway design to provide treatment and nutrient uptake from storm water runoff generated from the surface of the roadway. In addition, the toe of the slope of the roadway will be replanted with native vegetation, and the edge of the fill area will be meandered to save some existing vegetation. It is anticipated that the roadway could result in runoff containing from .17 to .18 pounds per day of nitrogen, and from .01 to .07 pounds per day of phosphate. The grassy swales proposed for inclusion in the project design have the capability of assimilating from 1.8 to 3.6 pounds of these nutrients per day, thereby ensuring a significant safety factor. It can also reasonably be anticipated that the swale areas are capable of absorbing any BOD loading from the roadway surface. As a result, it can reasonably be anticipated that the construction of the project will not result in the discharge of nutrients into the Strand, and that any heavy metals will be bound in organic sediments and not result in degradation of existing water quality. Ambient water conditions in the Strand show low dissolved oxygen content together with high biochemical oxygen demand, neither of which should be exacerbated by construction of the project. No violation of water quality criteria relating to herbicides is anticipated in view of Lee County's commitment at final hearing in this cause to control vegetation by way of mowing instead of by the use of herbicides. The proposed construction will, of course, destroy aquatic vegetation in the area lying in the path or "footprint" of the roadway itself, consisting of approximately seven and one-half acres, three acres of which are predominantly cypress. However, because of the design features of the proposed roadway, including grass, collector and spreader swales and the culvert system, the anticipated impact on the hydroperiod upstream and downstream of the project, and thereby the effect on aquatic vegetation and water quality will not be significant. Construction fabric will be used to allow the road surface to be supported without demucking, thus minimizing turbidity during construction periods, although it is intended that construction be conducted during the dry season, thereby further reducing the potential for turbidity violations. Further, the detention swales which are to be equipped with French drains are designed to retain the first inch of rainfall. Culverts to be constructed on the roadway are designed to accommodate a 50-year, 24-hour storm event. The Secretary of DER issued the subject permit on August 18, 1981, without any prior notice of intent. ASSWF received notice of DER's action in the form of a complete copy of the permit on August 27, 1981. On September 2, 1981, ASSWF filed its petition requesting a formal Section 120.57(1), Florida Statutes, hearing. This petition was received by DER on September 8, 1981. ASSWF and Audubon, and the members of these organizations, use the Six Mile Cypress Strand in the vicinity of the proposed project for field trips and environmental education activities which will be impacted should the project be approved. In addition, Audubon owns property within the Strand which may also be affected by the proposed project if permitted. Intervenors, Community Council and Lehigh Acres of Florida, Inc., Ralph Marciano, Claudia Tipton and H. Mark Strong requested to be granted party status in this proceeding in support of the application. Ralph Marciano owns a business allegedly limited because of the present poor highway access to the business center of the city. Claudia Tipton owns an electrical construction business alleged to be seriously hampered because of extended transportation time in emergency trips. H. Mark Strong is a retired fire marshal and contends that paramedics are seriously hampered in transporting emergency patients to the community hospital located in Fort Myers. The Community Council of Lehigh Acres was formed to serve as a council representing the entire community of Lehigh Acres on problems and projects affecting the health, welfare, growth and prosperity of Lehigh Acres. Essentially, these intervenors assert that the general public welfare and, in some cases, their own personal business interests, will be enhanced by building the proposed roadway, thereby enhancing vehicular access to various portions of the community.
The Issue The issues in this matter concern Petitioner's requests of Respondent to be granted an after-the-fact dredge and fill permit related to the placement of fill. See Chapters 253 and 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code. Respondent denied this request and this occasioned the formal hearing of February 10, 1984.
Findings Of Fact Petitioner placed a bulkhead waterward of the line of mean high water and the landward extent of the St. Johns River in Duval County, Florida, to improve his property. He then placed approximately 140 cubic yards of fill material in existing wetlands which were located landward of the bulkhead. This was done without obtaining an environmental permit from Respondent. Subsequently, Petitioner discovered that such permit was necessary and on April 28, 1983, he applied to the Department of Environmental Regulation for the issuance of an after-the-fact dredge and fill permit in keeping with the requirements of Chapters 253 and 403 Florida Statutes, and Chapter 17-4, Florida Administrative Code. An on-site inspection was made by reviewing authorities within the Department of Environmental Regulation and, based upon an appraisal of the project, the Department issued a Notice of Intent to Deny the application. The date of the notice was August 15, 1983. A Final Order related to the environmental permit request was issued on August 29, 1983, conditioned upon failure of the Respondent to apply for an administrative hearing within 14 days of the date of that order. Petitioner filed a Request for Formal Hearing on August 31, 1983, and the formal hearing ensued. The placement of the bulkhead and fill material was approximately 15 feet waterward of the line of mean high water in the St. Johns River and 30 feet waterward of the landward extent of the St. Johns River according to the plant indices set forth in Rule 17-4.02(17), Florida Administrative Code. The St. Johns River is a Class III water body and is a navigable waterway over which the state retains possessory and public trust rights. Notwithstanding the fact that the Petitioner has obtained permission from the State of Florida, Department of Natural Resources, related to property rights and utilization of the waters of the St. Johns River in the area of his project, he is not relieved from obtaining an environmental permit from Respondent. The Department of Environmental Regulation has jurisdiction over the construction of the bulkhead and the placement of the fill in the landward extent of St. Johns River, according to Chapters 253 and 403, Florida Statutes, and the associated rules of the Department. The landward extent of the waters of the St. Johns River was determined by the existence of smooth cordgrass (Spartina alterniflora), the dominant vegetation of the area filled by the Petitioner and a variety listed in Rule 17-4.02(17), Florida Administrative Code, as an indicator species of the Department's jurisdiction. That vegetation was covered over by the fill material along the 100-foot wide front in which the fill was placed. The previous existence of smooth cordgrass was established by testimony of the Petitioner's son and the continuing existence of that species in a property adjacent to the Petitioner's land along the St. Johns. The effect of the placement of the fill landward of the bulkhead caused the removal of approximately 1,200 to 1,500 square feet of tidal marsh. That tidal marsh was a vital part in the maintenance of water quality in the St. Johns River. In effect, the vegetation and microbiopopulation in soils served to filter out and assimilate pollutants from upland runoff and from the water in the river, and with the placement of the fill those resources and protections were destroyed. Moreover, water quality standards within Chapter 17-3, Florida Administrative Code, were also adversely impacted with the installation of the fill, including those standards related to BOD, dissolved oxygen, nutrients, and turbidity. Petitioner not only failed to give reasonable assurances that the placement of the fill in its short-term implication would not violate the aforementioned water quality criteria, he has also failed to give reasonable assurances that there will be no violations in the long-term results of the placement of fill. The destruction of the tidal marsh is detrimental to the ecological system in that it takes away detritus which is a necessary part of the food chain. Removal of the marshland is detrimental to the conservation of fish, marine and wildlife, and other natural resources. Petitioner has failed to affirmatively demonstrate that the quality of this detriment will not be contrary to the public interest. In fact, Respondent's presentation shows that the activity of the placement of fill is contrary to the public interest because of the adverse impacts on the natural resources of the area, in that natural marine habitats and grass flats suitable to nursery or feeding grounds for marine life were destroyed when the marshland was removed.
Findings Of Fact THE PARTIES The Respondent is the successor agency to the Florida Department of Environmental Regulation and has permitting authority over the subject project pursuant to Chapter 403, Florida Statutes. The Respondent's file number for this matter is 311765419. Petitioner, Alden Pond, Inc., is a subsidiary of First Union National Bank of Florida and is the successor in interest to Orchid Island Associates. John C. Kurtz is the designated property manager for this project and appeared at the formal hearing as Alden Pond's authorized agent. THE PROPERTY AND THE VICINITY Petitioner has record title to all of Government Lot 9 in Section 15, Township 31 South, Range 39 East, less the Jungle Trail Road right of way, and all of Government Lots 2, 3, 6, and 7, Section 22, Township 31 South, Range 39 East, less the road right of way for State Road 510. Petitioner does not own land below the mean high water line of the Indian River, which forms the western boundary of the property. Much of the property, approximately the northern half, abuts a part of the Indian River that has been leased by the State of Florida to the United States Fish and Wildlife Service as part of the Pelican Island National Wildlife Refuge. The Pelican Island National Wildlife Refuge was the first national wildlife refuge established in the United States and has been declared to be a water of international importance. Upland of the proposed project is a golf course and residential development. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II Outstanding Florida Waters. The Indian River in the vicinity of the project is part of the Intercoastal Waterway system, is navigable by large vessels, and is an important travel corridor for manatees. The Indian River in the vicinity of the project is a healthy estuarine system. Minor deviations from Respondent's dissolved oxygen standards have been recorded. These minor deviations are typical and represent natural conditions for this type of system. Water quality sampling from March 1994 yielded no samples in which deviations from Respondent's dissolved oxygen standards were observed. THE ORIGINAL PROJECT On February 21, 1990, Orchid Island Associates submitted to the Respondent an application for a wetland resource permit to construct a boat basin and canal on its property adjacent to the Indian River. The artificial waterway that Petitioner proposes to construct on its property will, for ease of reference, also be referred to as a canal. Petitioner proposes to dredge from the north terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the hydrological channel. Petitioner proposes to dredge from the south terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the access channel. The original project involved, among other features, a canal approximately 6,400 feet long, the dredging of the hydrological channel and the access channel, the construction of 44 docks to be located along the eastern side of the canal, and the dredging of an area adjacent to the canal for a 58 slip marina. The width of the canal was to range between 100 and 200 feet. The original project required the filling of 4.72 acres of wetlands and the dredging of 8.81 acres of wetlands for a direct impact on 13.53 acres of wetlands. On January 15, 1991, Respondent issued a preliminary evaluation letter pertaining to the initial application that contained the following conclusion: "the project cannot be recommended for approval." On September 12, 1991, Respondent issued a Notice of Permit Denial dated September 12, 1991, which stated that the application would be denied. This denial letter did not suggest any revisions that would make the project permittable and represented a strong position by the Respondent that the project as originally proposed should be denied. The September 12, 1991, Notice of Denial correctly described the project site and the initial proposal as follows: . . . The proposed project is located north of and adjacent to County Road 510, north and east of Wabasso Bridge and adjacent to the eastern shore of the Indian River. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II, Outstanding Florida Waters. The Pelican Island National Wildlife Refuge, also an aquatic preserve and an Outstanding Florida Water, is immediately west of the project site. Historically, the site of the marina and its associated upland development consisted of a wetland adjacent to the Indian River and a large citrus grove. Subsequently, the wetland was surrounded by a dike and impounded for mosquito control purposes. At some point in the past, a borrow pit 1/ was excavated within the landward (eastern) edge of the impounded wetland. Most of the citrus grove has been converted to a residential community associated with a golf course. * * * The proposed project included excavation of a 6,400 linear ft. canal along the upland/wetland edge between the impoundment and the adjacent upland, dredging the existing borrow pit to a depth of -8 ft. NGVD to create a boat basin that will connect it to the excavated canal, construction of 58 boat slips within the excavated boat basin, excavation of two flushing channels through a portion of the impoundment dike and wetlands within the impoundment to connect the excavated channel to the Indian River and a natural lake within the impoundment, excavation of a 700 ft. long access channel to connect the excavated canal to the Intercoastal Waterway through the seagrass beds along the southern boundary of the project site, filling of 4.72 ac. of wetlands at three locations within the impoundment to create uplands, and construction of a boardwalk along the southern edge of the excavated canal through the wetlands in the impoundment to provide access to the marina basin. To mitigate for the loss of wetlands, the applicant proposes to enhance 68 ac. of wetlands within the mosquito impoundment by returning the impoundment berm to grade and implementing a rotary ditching project and open marsh mosquito management to improve the hydrology of the wetlands in the impoundment, planting high marsh species, and donating the enhanced wetlands to the State of Florida for incorporation into the Pelican Island National Wildlife Refuge through a lease to the United States Fish and Wildlife Service. The September 12, 1991, Notice of Denial provided, in pertinent part, the following reasons for the denial of the project: The Department hereby denies the permit for the following reasons: Water quality data for the Indian River adjacent to the project site indicates that the dissolved oxygen (D.O.) standard is not currently being met. The proposed 8 ft. deep canal and marina basin to the Indian River would be expected to result in introduction of additional low D.O. waters into a system which already does not meet the D.O. standard, thereby resulting in further degradation of the water quality in the Indian River. In addition to the D.O. problem, the project would result in water quality degradation due to the pollutant loading of marina related pollutants from the boats docked at the 58 slips that are proposed as part of the project in the marina basin. Additional water quality degradation also may result from boats that are moored at docks that may be constructed at a later date by the owners of the 44 lots adjacent to the canal, pursuant to the exemption in Section 403.813(2)(b), Florida Statutes. This exemption provides that private docks in artificially constructed waters are exempt from dredge and fill permitting and may be constructed without a permit providing they meet the size criteria listed in the statute and provided they do not impede navigation, affect flood control, or cause water quality violations. The boats in the canal system and boat basin would be a chronic source of pollutants for the life of the facility. The proposed water depths and slip sizes will make the basin accessible for use by large boats which can be expected to have on-board sanitation devices. The hydrographic report submitted by the applicant indicates the proposed waters will flush with a 2.6 hr. duration. Although this flushing rate will prevent water quality pollutants from being concentrated in the waters of the basin, it also will have the effect of transporting boat related pollutants to the Indian River, thereby causing degradation of the Outstanding Florida Water. The project site is within Class II Waters, prohibited for shellfish harvesting, but is adjacent to Class II Waters, approved for shellfish harvesting. Discussion with the Department of Natural Resources, Bureau of Regulation and Development, indicates that the pollutant loading from the project would probably cause the adjacent waters to be reclassified as "prohibited for shellfish harvesting." The reclassification of the adjacent waters would lower the existing use of the waterbody. Rules 17-302.300(1), (4), , and (6), Florida Administrative Code, state that: Section 403.021, Florida Statutes, declares that the public policy of the State is to conserve the waters of the State to protect, maintain, and improve the quality thereof for public water supplies, for the propagation of wildlife, fish and other aquatic life, and for domestic, agricultural, industrial, recreational, and other beneficial uses. It also prohibits the discharge of wastes into Florida waters without treatment necessary to protect those beneficial uses of the waters. * * * Existing uses and the level of water quality necessary to protect the existing uses shall be fully maintained and protected. Such uses may be different or more extensive than the designated use. Pollution which causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Waters having water quality below the criteria established for them shall be protected and enhanced. However, the Department shall not strive to abate natural conditions. If the Department finds that a new or existing discharge will reduce the quality of the receiving waters below the classification established for them or violate any Department rule or standard, it shall refuse to permit the discharge. As a result of the above cited factors, degradation of water quality is expected. The applicant has not provided reasonable assurance that the immediate and long-term impacts of the project will not result in the degradation of existing water quality in an Outstanding Florida Water and the violation of water quality standards pursuant to Rules 17-312.080(1) and (3), Florida Administrative Code, and Rule 17-4.242(2)(a)2.b, Florida Administrative Code. Specific State Water Quality Standards in Rules 17-302.500, 17-302.510 and 17-302.550, Florida Administrative Code, affected by the completion of the project include the following: Bacteriological Quality - the median coliform MPN (Most Probable Number) of water shall not exceed seventy (70) per hundred (100) milliliters, and not more than ten percent (10 percent) of the samples shall exceed a MPN of two hundred and thirty (230) per one hundred (100) milliliters. The fecal coliform bacterial level shall not exceed a median value of 14 MPN per 100 milliliters with not more than ten percent (10 percent) of the samples exceeding 43 MPN per 100 milliliters. Dissolved Oxygen - the concentration in all waters shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter. Normal daily and seasonal fluctuations above these levels shall be maintained. Oils and Greases: Dissolved or emulsified oils and greases shall not exceed 5.0 milligrams per liter. No undissolved oil, or visible oil defined as iridescence, shall be present so as to cause taste or odor, or otherwise interfere with the beneficial use of waters. In addition the applicant has not provided reasonable assurance that ambient water quality in the OFW will not be degraded pursuant to Rule 17-4.242(2)(a)2.b, Florida Administrative Code. In addition, pursuant to Rule 17-312.080(6)(a), Florida Administrative Code, the Department shall deny a permit for dredging or filling in Class II waters which are not approved for shellfish harvesting unless the applicant submits a plan or proposes a procedure to protect those waters and waters in the vicinity. The plan or procedure shall detail the measures to be taken to prevent significant damage to the immediate project areas and to adjacent area and shall provide reasonable assurance that the standards for Class II waters will not be violated. In addition to impacts to water quality, the project is expected to adversely affect biological resources. A portion (estimated at between 0.4 and 0.5 ac.) of the access channel alignment is vegetated by seagrasses, the dominant species being Halodule wrightii (Cuban shoal weed). Seagrass beds provide important habitat and forage for a variety of wildlife species. The loss of seagrass beds will result in a loss of productivity to the entire system that would be difficult to replace. The 4.72 ac. of wetlands proposed to be filled and the excavation required for the proposed channels (approximately 38 ac.) are productive high marsh and mixed mangrove wetlands which are providing wildlife habitat and water quality benefits. These wetlands have been adversely impacted by the freeze of 1989, but they appear to be recovering well. The proposed mitigation would provide some benefits through exotic removal and increased hydrologic connection to the Indian River. However, these benefits would not be adequate to offset the adverse impacts of the proposed wetland losses for this project. The project site and the adjacent Pelican Island National Wildlife Refuge are used for nesting and foraging by a variety of species, including little blue heron (Egretta caerulea) (Species of Special Concern (SSC)--Florida Game and Fresh Water fish Commission (FGFWFC)), reddish egret (E. rufescens) (SSC-FGFWFC), snowy egrets (E. thula) (SSC-FGFWFC), tricolored herons (E. tricolor) (SSC-FGFWFC), brown pelicans (Pelecanus occidentalis) (SSC-FGFWFC), roseate spoonbills (Ajaja ajaja) (SSC-FGFWFC), least tern (Sterna antillarum) (threatened-FGFWFC), and wood storks (endangered-FGFWFC). The construction of the project and the increased boating activity due to the project would result in the disturbance of those species that use the wetlands in the project area. The Indian River adjacent to the project site is used by the West Indian Manatee (endangered-FGFWFC). The increased boat traffic would increase the chance of manatee deaths due to boat impact. In addition, the excavation of the access channel through the seagrass beds would decrease the available forage for manatees in the project area. For the above reasons, this project is also not clearly in the public interest, as required pursuant to Section 403.918(2), Florida Statutes, because it is expected to: adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; be permanent in nature; diminish the current condition and relative value of functions being performed by areas affected by the proposed activity. The applicant has not provided reasonable assurance that the project is clearly in the public interest. On September 12, 1991, the owner and holder of the mortgage on the Orchid Island development (which includes the real property on which the Petitioner hopes to construct the project at issue in this proceeding) instituted foreclosure proceedings. The circuit judge who presided over the foreclosure proceeding soon thereafter appointed an interim receiver to manage the property until a receiver who would manage the property for the duration of the foreclosure proceeding could be appointed. THE PROJECT MODIFICATIONS AND FACTS AS TO ESTOPPEL On October 31, 1991, representatives of Orchid Island Associates met with Respondent's staff to discuss this application. Trudie Bell, the Environmental Specialist assigned to supervise this application, and Douglas MacLaughlin, an attorney employed by Respondent, attended the meeting. Those attending the meeting on behalf of Orchid Island Associates included the interim trustee, the attorney for Orchid Island Associates, and Darrell McQueen, who at all times pertinent to this proceeding was the project engineer. Mr. McQueen was upset that the project was going to be denied and wanted to know what could be done to make it a permittable project. In response to Mr. McQueen, Ms. Bell, without making any promises, suggested the following modifications to the project that might make it permittable: moving the canal more upland, elimination of the boat basin/marina, reducing the depth of the artificial waterway, and increasing the width of the littoral zone. On November 11, 1991, the representatives of Orchid Island Associates responded to the Respondent's suggested modifications and agreed to make the modifications. In an effort to design a project that would be acceptable to Respondent, Orchid Island Associates proposed to the Respondent to make certain modifications to the design of the project. Petitioner has agreed to those modifications which include the following: Elimination of the boat basin and associated 58 dock marina and clubhouse, but with the addition of 18 relatively narrow residential lots, each of which would have a dock on the south end of the waterway. 2/ Reduction of the depth of the artificial waterway to -7 feet NGVD from the proposed -8 feet NGVD. Realignment of the artificial waterway as depicted on the sealed drawings submitted to Respondent and dated January 28, 1993. Increasing the width of the littoral zone to be created along the length of the artificial waterway to 40 feet on the west side and 10 feet on the east side. On November 12, 1991, John C. Kurtz was appointed the receiver of the Orchid Island Associates property and remained the receiver until the property was conveyed to Petitioner at a foreclosure sale on July 31, 1993. After it acquired the property, Petitioner employed Mr. Kurtz to manage the subject property. Mr. Kurtz has been active in the project since his appointment as the receiver of the property. On November 21, 1991, Petitioner met with Respondent's staff, including Ms. Bell, to discuss the modifications. At that meeting, the Respondent's staff reacted favorably to the modifications agreed to by Petitioner. Ms. Bell described the revisions as "excellent" and "a great idea" and stated that the project was "a nice project" and that it looked like the project was heading in the right direction. Ms. Bell also represented that the Respondent would grant the Petitioner extensions of time to allow for a formal revision if the project was deemed permittable. Ms. Bell kept her superiors informed of the status of her review. On December 11, 1991, Charles Barrowclaugh, an employee of the Respondent, made an inspection of the site and informed representatives of the Petitioner that he had briefed Carol Browner, who was Secretary of the Department of Environmental Regulation, as to the project and the proposed modifications. Mr. Barrowclaugh stated that he believed the project was permittable. Petitioner was encouraged by Mr. Barrowclaugh's comments and by the fact that he would incur the expenses of traveling to the site. Between December 11, 1991, and November 13, 1992, Petitioner provided information to Respondent pertaining to the revised project. This additional information included a description of the revised plan and a revised schematic drawing, but it did not include detailed drawings of the revised project. On November 13, 1992, Ms. Bell wrote to Mr. McQueen a letter that stated, in pertinent part, as follows: The Bureau of Wetland Resource Management has reviewed the revised plan and additional information submitted on September 16. The revised proposal appears to address all of the issues that made the original proposal unpermittable. The detailed 8.5 by 11 inch permitting drawings will have to be revised to reflect the revised proposal and submitted to the Bureau for review. Kelly Custer and Orlando Rivera will be reviewing the project in the future. Petitioner interpreted that letter to mean that the Respondent intended to permit the project. At the time she wrote the letter of November 13, 1992, Ms. Bell thought the revised project would be permitted. Petitioner relied on the oral representations made by Respondent's staff and on the November 13, 1992, letter in continuing pursuit of a permit. Absent these encouraging comments by Respondent's staff, Petitioner would have discontinued pursuit of the permit. Although Petitioner was understandably encouraged by the discussions its representatives had with Respondent's staff, it knew, or should have known, that the favorable comments it was receiving from members of Respondent's staff were preliminary and that additional information would be required and further evaluation of the project would take place. Petitioner's representatives knew that the staff with whom they were having these discussions did not have the authority to approve the application, but that they could only make recommendations to their superiors. In late 1992, Kevin Pope, an Environmental Specialist employed by Respondent, was assigned as the primary reviewer of the revised project. At the time he became the primary reviewer of the project, Mr. Pope did not make an immediate, independent evaluation of the project, and relied on what other staffers who had been involved in the review told him. Until he conducted his own review of the project, Mr. Pope believed that the project was "clearly permissible". Mr. Pope informed a representative of the Petitioner of that belief and told the representative that he was prepared to start drafting the permit once he received final drawings documenting the modifications to the project. Subsequent to that conversation, Mr. Pope received the drawings he requested. After he received and reviewed the final drawings, Mr. Pope determined that all issues raised by the denial letter had not been addressed. Among the concerns he had was the fact that the project would dredge into the Indian River to the Intercoastal Waterway and that part of the dredging activity (at the north end of the project) would be in Class II shellfish approved waters. Mr. Pope again contacted the state and federal agencies that had originally commented on the project, described the proposed modifications to the project, and requested comments. Most of the agencies continued to object to the project. On August 5, 1992, Mr. Pope held a meeting with the commenting agencies and with representatives of the Petitioner to discuss the objections to the project. 3/ The agencies provided additional comments after this meeting and most continued to oppose the project. Mr. Kurtz testified that on June 1, 1993, Stacey Callahan, an attorney employed by Respondent, told him that she was attempting to draft the permit for the project. Ms. Callahan asked for sample wording for a restrictive covenant or for an easement that would limit the number of boats that could use the proposed docks. Subsequent to that inquiry, Petitioner was informed by Mr. Pope that the project would be denied. Petitioner has not made any specific proposal to assure a limitation on the number of boats that will be able to dock in the proposed canal. In June of 1993, a large number of objections to the project were filed with Respondent by members of the public. In early July, 1993, Secretary Wetherell responded to those objectors with a letter stating, in part, that the "Department's letter of November 1992 indicating an intent to issue for the project was imminent appears to have been premature." On September 20, 1993, Mr. Pope informed Petitioner's attorney that the Respondent was not going to change its position that the project, even with the modifications, should be denied. The decision not to permit the modified project was made by Mr. Pope. The only permit application filed by the Petitioner was the application for the initial permit. No formal amended application that incorporates all of the changes that Petitioner discussed with Respondent's staff was filed. A total of $74,735 was spent on behalf of the applicant on this project between December 26, 1991, (the date of the meeting with Mr. Barrowclaugh) and July 31, 1993, (the date the property was conveyed to Petitioner). From July 31, 1993, through April of 1994, Petitioner spent an additional $47,488 on the application for this project. The expenditures after July 31, 1993, included engineering costs that were incurred before that date. These figures do not include the costs of this proceeding. THE REVISED PROJECT The revised project may be summarily described as follows: Petitioner proposes to construct a canal that will be approximately 6,400 feet long, up to 200 feet wide, and -7 NGVD deep as depicted on drawings that have been submitted into evidence. There will be a littoral zone 40 feet wide on the west side of the canal and a littoral zone 10 feet wide on the east side. A hydrological channel, proposed from the north terminus of the canal to the Intercoastal Waterway to enable a proper flow of water through the canal, will be some 200 feet wide, 70 feet in length, and -3 NGVD. Petitioner proposes to construct a barrier at the north terminus of the canal to prevent manatees and boats from entering the canal from the north and has agreed to maintain that barrier. An access channel, proposed from the south terminus to the Intercoastal Waterway to enable boats access to the canal, will be some 200 feet wide, 700 feet in length, and -7 NGVD. A total of 62 docks are proposed. The project includes a mitigation plan that will be discussed below. THE REQUESTED VARIANCE The construction of the hydrological channel would be in Class II conditionally approved shellfish waters. Dredging in Class II conditionally approved shellfish waters is prohibited unless a variance is issued by Respondent that would permit this otherwise prohibited activity. Petitioner's attorney submitted a letter to the Respondent on August 18, 1993, for a variance to construct the channel from the north terminus of the canal to the Intercoastal Waterway. That letter stated, in pertinent part, as follows: DEP Rule 17-312.080(17) states: "Permits for dredging or filling directly in Class II or Class III waters which are approved for shellfish harvesting by the Department of Natural Resources shall not be issued." This provision is applicable to the pending application by Orchid Island Associates. Accordingly, we discussed Orchid Island requesting a variance pursuant to Section 403.201, Florida Statutes, and Rule 17-103.100, Florida Administrative Code, as a means of overcoming this prohibition. Since the dredge and fill application is pending, you indicated it would be appropriate for Orchid Island to ask, during final review of this application, that the Department also consider a request for a variance pursuant to the above mentioned statute and rule. Please consider this letter that request. . . . Petitioner did not submit along with its request the fee required by Respondent to process that request. Respondent did not advise Petitioner that it would not process its request without the requisite application fee until the prehearing stipulation was prepared for this proceeding shortly before the formal hearing. There was no evidence that Petitioner attempted to check on the status of its request for a variance or that it expected Respondent to act on the request for a variance independent of its final review of the overall project. As of the time of the formal hearing, Petitioner had not submitted to Respondent the fee that Respondent asserts is required before the request for the variance will be processed. Respondent asserted that position in the prehearing statement that was filed shortly before the formal hearing. The evidence as to the flow of water through the proposed canal assumed the existence of the hydrological channel from the north terminus of the proposed canal to the Intercoastal Waterway and the existence of the access channel from the south terminus of the proposed canal to the Intercoastal Waterway. CONSTRUCTION OF THE PROJECT The revised version of the artificial waterway will be excavated primarily from uplands, but the excavation will require that 3.6 acres of wetlands be filled and 7.1 acres of wetlands be dredged. The direct impact on wetlands will be at least 10.7 acres. The mitigation plan proposes that the berms around the mosquito impoundment will be leveled, the berm ditches will be filled, and certain rotary ditches will be dredged. The amount of wetlands to be impacted by that proposed activity was not established. The artificial waterway will be constructed utilizing a series of separate construction cells, a rim ditch, and filtration chambers. All excavated material will be disposed of on uplands. The construction system will filter most solids. Turbidity suppression devices will be used to minimize any turbidity associated with the excavation of the access channel at the south terminus and the hydrological channel at the north terminus. Petitioner established that its proposed construction techniques are consistent with best management practices. The small body of water that is referred to as the former borrow pit in the denial letter of September 12, 1991, is known as Boot Lake. Petitioner proposes to dredge the eastern end of Boot Lake, consisting of an area 800 feet by 180 feet (3.3 acres), to create part of the canal. The access channel at the south terminus of the canal will be approximately 700 feet in length and will have to be hydraulically excavated in the Indian River to connect the canal to the Intercoastal Waterway. The hydrological channel at the north terminus of the canal will be hydraulically excavated to connect the canal to the Indian River. The connection will require approximately 70 feet of dredging to -3 NGVD, which is the minimum necessary to maintain the proper flow of water through the canal. HYDROLOGY OF THE CANAL The artificial waterway will function as a flow-through system driven by a difference in the water surface elevation (the head difference) between the north terminus and the south terminus. The flushing of the artificial waterway far exceeds the Respondent's flushing requirement benchmark, which is a flushing time of four days. If a hypothetical pollutant's concentration is reduced to 10 percent of its initial concentration in four days, the flushing is considered to be acceptable. The flushing time for the system is approximately 2.6 hours, which will produce five total volume replacements per tidal cycle. The predicted flushing of the artificial waterway is quite rapid and energetic. The predominate flow of water in the artificial waterway is from north to south. At times, however, the flow will be from the south to the north. At the request of the Respondent, Petitioner conducted a tracer dye study within the Indian River at the proposed south terminus of the artificial waterway. No tracer dye study was requested for the north terminus. Although there was some disagreement as to the import of the tracer dye study, it established that pollutants introduced into the Indian River from the canal would be rapidly dispersed in the Indian River. WATER QUALITY - THE CANAL The artificial waterway will be classified as Class III waters of the State. Water quality within the artificial waterway will reflect the current water quality in the Indian River. Petitioner has provided reasonable assurances that the water quality within the artificial waterway itself will not violate state standards. Two potential sources of pollutants to the artificial waterway have been identified. The first source is stormwater runoff through the stormwater management system associated with the upland development. The second is pollution inherent with the docking and operation of large vessels. Respondent interprets its rules so that discharge of pollutants into the artificial waterway will constitute indirect discharges to the Indian River. Because of the excellent flushing capacity of the canal, pollutants will not tend to accumulate in the canal. A pollutant entering the canal or a spill of pollutants into the canal will mix very little in the canal, probably less than five percent, so the pollutant will discharge from the canal into the Indian River as a plug. There was a conflict in the evidence as to whether pollutants introduced into the canal will enter the Indian River in measurable quantities. Testimony was elicited from Dr. Roessler, one of Petitioner's experts, that water entering the Indian River from the artificial waterway will not contain pollutants that are either measurably or statistically differentiable from the Indian River itself. That result depends, however, on the amount and the source of the pollutant introduced into the canal. Because of the rapid flushing of the canal, small spills or slowly released discharges of pollutants are not expected to result in water quality degradation in the Indian River. Since a pollutant introduced into the canal will exit in a plug essentially in the same concentration as it entered the canal, Petitioner has not provided reasonable assurances that large spills or discharges of pollutants from vessels or from other sources will not be discharged into the Indian River in concentrations that can be measured or that such large spills or discharges will not degrade the quality of the Indian River. Water from the canal will come out of both the north end and the south end of the canal. Some of the plume coming out of the north end may tend to hug the shoreline, with some of the plume reentering the canal when the tides change. Stormwater runoff contains significant amounts of fecal coliform, sometimes more than raw sewage. The stormwater management system associated with the upland development was permitted by the St. Johns Water Management District. The majority of the system is currently in place and functioning to retain stormwater runoff. The stormwater management system is designed to retain all of the first 4.75 inches of rainfall and most of the first 6.2 inches of rainfall. The design of this system exceeds the requirements imposed by the St. Johns Water Management District, which is that the first 1.5 inches of rainfall be retained. Stormwater management regulations are technology-based treatment criteria. If a system meets the retention requirement, it is presumed that no water quality will be violated by discharges through the system. Petitioner established that the stormwater management system was designed and constructed to retain at least three times the amount of rainfall required by the St. Johns Water Management District. Construction of the proposed canal will intercept two stormwater discharge pipes from the upland golf course and residential development. There was no evidence that the St. Johns Water Management System has reviewed this change in the system that has been permitted. The proposed change in where the outflow will be discharged could be significant since the discharge pipes are presently designed to discharge overflows from the system into wetland areas that provided additional natural treatment of the overflow before the overflow reaches the Indian River. With this change the overflow will be discharged during extraordinary storm events into the canal and thereafter into the Indian River without additional natural treatment. Because there will be modifications to the stormwater system the approval of that system by the St. Johns Water Management District should not be relied upon as providing reasonable assurances that no water quality violations will be caused by stormwater discharge. If this project is to be permitted, Petitioner should be required as a condition precedent to the issuance of the permit to have the proposed changes to the system reviewed by the St. Johns Water Management District and it should be required to obtain an amendment to the stormwater management system permit that would authorize the proposed changes. The project contemplates the construction of 62 docks. The size and the docking capacity of each dock has not been established. While Petitioner presented testimony that it is likely that only 50 percent of the docks will likely be used at any one time, that testimony is considered to be speculative. The number and size of boats that can or will be docked in the canal at any one time or on a regular basis is unknown. It is likely that each dock will have docking capacity for at least one vessel up to 60 feet in length and for a smaller vessel. The manner in which these docks will be constructed was not established. Chromatic copper arsenic, which is frequently used to coat docks and anti-fouling paints containing heavy metals used on boats are sources of contamination to shellfishing. Oils and greases from boats contain hydrocarbons which can adversely impact shellfish. These contaminants can have adverse impacts to shellfish at very low concentrations. Petitioner has agreed to prohibit live-aboard vessels and to prohibit the fueling and maintenance of vessels within the artificial waterway. Sewage containing fecal coliform dumped or spilled from boats or from stormwater discharge is a primary source of contamination for shellfishing waters. It is the practice of the Respondent's Shellfish Environmental Assessment Section to close waters to shellfishing in the vicinity of marinas, mainly due to potential contamination from untreated sewage. The Shellfish Environmental Assessment Section does not recommend the immediate closing of shellfishing waters when a project involves single family docks associated with a residence because it assumes people will use bathroom facilities in the house instead of on the boat. The Respondent does not have reasonable assurances that there will be houses associated with each of the 50 foot lots designated at the southern end of the canal. If a proposed facility has boat docks, but does not have houses associated with each dock, the Shellfish Environmental Assessment Section would recommend closure of shellfishing in the vicinity of the facility. The Shellfish Environmental Assessment Section would not recommend immediate closure of the shellfishing waters in the vicinity of this proposed project because it has assumed that each of the proposed docks will be associated with a house. If this project is to be permitted, reasonable assurances should be required that a residence will be constructed before or contemporaneously with the construction of a dock. The modifications made by Petitioner to the project will reduce the danger of pollutants from vessels in the artificial waterway. However, because the number and the size of the vessels that will be using the artificial waterway was not established, the extent of pollutants from vessels is unknown. Consequently, it is concluded that Petitioner did not provide reasonable assurances that measurable pollutants would not indirectly discharge into the Indian River from the canal. IMPACT ON WETLANDS Of the approximately 10.70 acres of wetlands that will be directly impacted by the proposed waterway, 4.10 acres are predominately impacted by invasive exotic (non-native) plants, 4.27 acres are somewhat impacted by exotic plants, and 2.23 acres are not impacted by exotic plants. The exotic plants found at the project site are primarily Australian Pine and Brazilian Pepper. The mitigation plan, which will be discussed below, proposes that the berms constructed around the mosquito impoundment area be removed and the rim ditches that abut the berms be filled. The amount of wetlands to be impacted by that activity was not established. The project contemplates that rotary ditches will be constructed at different places in the mosquito impoundment area after the berms are removed and the berm ditches filled. The areas to be impacted by the construction of the rotary ditches were not identified. The Petitioner proposes to dredge out the entire east end of Boot Lake for use as part of the canal. This area will be approximately 800 feet by 180 feet and will be 3.3 acres. Boot Lake is a fairly healthy biological system, about the same as the Indian River. It was found to contain 22 species of fish and seven species of birds, with brown pelican and the great blue heron dominant. Eleven species of crustacean, six species of mollusks, 24 vermes 4/ and one coelenterate were collected from the lake. Replacement of the eastern portion of Boot Lake with the canal will adversely impact those species. Between the Indian River and the proposed waterway is a mosquito impoundment constructed in the early 1960s. The mosquito impoundment and associated berms total approximately 105 acres. The exact area was not established since there is an unresolved issue as to the exact location of the mean high water line. 5/ The impoundment is breached in several locations and no longer functions efficiently as a mosquito impoundment. IMPACTS ON SEAGRASSES The excavation of the access channel from the south terminus to the Intercoastal Waterway will involve the removal of approximately 2500 square feet of a healthy, productive seagrass bed. Seagrasses are beneficial for wildlife habitat as they provide a substrate for algae and diatoms. Seagrasses are a direct food source for manatees and other species, and provide shelter and protection for fish. Seagrasses observed in this area where grasses will be eliminated are Halodule writtii, Syringodium filiforme, and Halophia johnsonii. Halophia, one of the identified species in this seagrass bed, is designated by the Florida Natural Areas Inventory as a rare and endangered species. Besides the seagrasses actually eliminated where the channel is to be constructed, other nearby seagrasses are also likely to be affected. The sides of the channel are likely to slough to some degree, which would adversely impact the seagrasses abutting the channel. The operation of power boats, even at slow speeds, will cause turbidity that will likely adversely impact seagrasses. Maintenance dredging, which will be required every few years, will cause turbidity that will likely adversely impact seagrasses. There are presently thousands of acres of seagrasses located within the Indian River. There has been a historical decline in seagrass in the Indian River Lagoon. Since 1950, there has been a 30 percent loss of seagrasses and seagrass habitat. IMPACTS ON SHELLFISH The proposed project will have an adverse impact on shellfish and shellfishing. At a minimum, the project will require dredging in a shellfishing area. The hydrological channel that will be dredged to connect the north terminus of the canal with the Intercoastal Waterway will be located in Class II waters that have been conditionally approved for shellfishing. Both commercial and recreational shellfishing occur in the Indian River adjacent to the project site. The predominate flow of water through the canal will be southerly. There will be, however, a predictable northerly flow of waters that will cause waters from the proposed canal and any associated contaminants contained in those waters to flow from the north terminus of the canal into the Class II waters that have been conditionally approved for shellfishing. The proposed project may introduce a significant amount of freshwater into the adjoining shellfishing waters of Indian River, primarily in the vicinity of the north terminus of the canal. Any additional freshwater discharges to shellfishing waters is a concern because fecal coliform bacteria survive longer in freshwater than saltwater. Three likely sources of freshwater that would be added by this project to the Indian River in the conditionally approved shellfishing area were identified by Respondent. First, the proposed canal appears to be intersecting near its north terminus with a sulphur spring or artesian well which produces fresh water with a high sulphur content. Fresh water will likely be introduced into the canal from this source and discharged into the shellfishing waters when the tidal flow becomes northward. Second, freshwater may be introduced into the canal from the overflow pipes from the surface water management system. This source of freshwater would not be significant. Third, additional freshwater may enter the area after the berms around the mosquito impoundment area are removed as contemplated by the mitigation plan. The extent of this source of freshwater was not established. If this project is permitted, the Shellfish Environmental Assessment Section will monitor this area for water quality to determine if the area will have to be closed for shellfishing. This additional monitoring, for which Respondent will pay, will be required because of the potential adverse impacts this project presents to shellfishing. Because of evidence of deteriorating water quality, the Shellfish Environmental Assessment Section is recommending that the shellfishing waters adjacent to the site be reclassified from "conditionally approved" to "conditionally restricted". In "conditionally restricted" waters, shellfish can still be harvested, but the harvested shellfish have to be placed in designated waters or in on-land facilities so the shellfish can cleanse themselves of fecal coliform before going to market. The conditions in the area of the proposed project are not yet bad enough to prohibit shellfishing. IMPACT ON MANATEES There are approximately 2,000 manatees living in Florida waters, with approximately 1,000 living on the east coast and approximately 1,000 living on the west coast. The manatee is an endangered species, and the long-term survival of the species is not secure. The Indian River in the area of the proposed project provides good habitat for manatees and is a major travel corridor for several hundred manatees. Indian River County is one of 13 key counties that has been designated by the Governor and Cabinet to address special manatee concerns. Manatees traveling back and forth in this area usually use the channel of the Intercoastal Waterway because it is deeper and allows manatees an easier travel route. Speed zones for boat traffic are an effective manatee protection mechanism. The artificial waterway will be posted as an idle speed zone. The area where the access channel connecting the south terminus of the canal with the Intercoastal Waterway will be dredged is presently designated as a slow speed zone and the access channel itself will be marked. Petitioner has agreed to implement Respondent's standard manatee conditions. Seagrasses are an important source of food for manatees. The project contemplates that 0.05 acres of seagrass will be dredged, but that Spartina will be planted in parts of the littoral zone. While manatees eat Spartina to some extent, they prefer seagrasses. Since there are thousands of acres of seagrass located in the Indian River, it is concluded that the elimination of 0.05 acres of seagrass associated with this project is negligible and will not adversely affect manatees. A barrier to navigation will be maintained at the north terminus of the waterway to preclude boat access and limit access to the waterway by manatees. Manatees would be unable to enter or leave the artificial waterway via the north terminus. The artificial waterway will not attract manatees and should not, in and of itself, adversely impact manatees. The main adverse impact to manatees from this proposed project is the threat of collisions by boats that leave the canal and enter the waters of the Indian River, including the Intercoastal Waterway. At least ten West Indian manatees have been killed by boats in Indian River County since 1981. Even with the speed limits, the increase in boating in this area will present an increased risk to manatees. IMPACT ON BIRDS No species of wading birds, including those listed as endangered or threatened, nests or roosts within the project site. The project site is not currently heavily utilized by wading birds, but several species of wading birds were observed foraging for food in Boot Lake. It is reasonable to expect that dredging of Boot Lake and the increased boat traffic will have an adverse impact on birds. Diving birds, such as the brown pelican and least tern, will benefit from the increased open waterway created by the canal, which should serve as a feeding habitat. Wading birds congregate and nest in rookeries. The area of the proposed project is within the foraging range of 14 active rookeries, and it is reasonable to expect that those rookeries will be disturbed by the increased boat use or human activity that the project will bring to this area. Officials of Pelican Island National Wildlife Refuge have observed such disturbances and are opposed to this project. The pressure of human and boating activities on bird rookeries in the Pelican Island National Wildlife Refuge, including human intrusion into buffer zones established to protect the birds, has resulted in a continuing decline of the bird population since 1960. When disturbed by boats or by humans, the parent wading bird will often leave the nest, which exposes the eggs or the chicks to attack by predators or to overexposure to sunlight. Boaters will often cause wading birds who are foraging for food to flush, which disturbs their search for food. Certain species of wading birds are flushed more frequently and for longer distances when flushed from narrow tidal creeks in Spartina marshes (a habitat similar to the proposed canal) than in open shoreline habitat. IMPACT ON FISH The existing ditches inside the mosquito impoundment berms presently provide a habitat similar to that of a tidal creek for a variety of fish, including juvenile snook, tarpon, red drum, black drum, lady fish, and mullet. The proposed project will result in the filling of these habitats and impoundments. As a consequence of that activity, these species of fish will be adversely impacted by the project. Although Petitioner proposes to construct certain rotary ditches that it asserts would provide a habitat similar to that provided by the existing ditches, Petitioner has not submitted any plans or drawings or other specific information concerning these rotary ditches and has not provided reasonable assurances that these proposed rotary will replace the habitat that will be eliminated by the filling of the existing ditches. CUMULATIVE IMPACTS Other projects have been permitted on the Indian River north and south of the proposed project that have increased boat traffic on the Indian River in the vicinity of the project. The Respondent has not identified any similar projects which have been permitted in the vicinity within the last five years. The only similar application pending before the Respondent in the vicinity of the project is for two docks north of the project site. Although Respondent established that boat traffic on the Indian River has increased, this project is unique in scope and design, and it is concluded that Petitioner has given reasonable assurances that no negative cumulative impacts will be associated with the project. OTHER PERMITTING CRITERIA The parties stipulated to the following facts that pertain to permitting criteria: The project will not adversely affect navigation or the flow of water. The project will not cause harmful erosion or shoaling. The project will be of a permanent nature. The project will not adversely affect any significant historical or archaeological resources. The project will not adversely affect the property of others. The proposed waterway will be located almost entirely on private property in areas not currently utilized for fishing or other recreational activities. Except for the impacts on shellfishing, birds, and fish discussed above, the project will not adversely affect the fishing or recreational values within the vicinity of the project. THE MITIGATION PLAN Petitioner has taken all reasonable steps to minimize the adverse impacts associated with the type project it is proposing. Because there will be adverse impacts to an Outstanding Florida Water, the project can be permitted only if it is determined that the mitigation plan offsets the adverse impacts and makes the project clearly in the public interest. Petitioner's mitigation plan was contained in the original application and was revised between October 1991 and January 1992. Respondent considered the current mitigation plan in its review of this project. The current mitigation plan consists of the creation of wetlands, the enhancement of wetlands, and the preservation and donation of wetlands owned by Petitioner within the mosquito impoundment. The estimated cost of creation and enhancement of the mitigation plan is $600,000. Petitioner proposes to create approximately 14 acres of wetlands by removing the mosquito impoundment berms and converting other uplands within the impoundment to wetlands. These areas will be revegetated with various wetland plant species including red, black, and white mangroves. In addition, Petitioner proposes to create a forty foot wide intertidal littoral zone along the entire length of the western side of the artificial waterway and a ten foot wide littoral zone along the entire eastern side of the artificial waterway. Approximately three acres of the littoral zone will be created from uplands. The littoral zone will be revegetated with 80 percent cord grass and 20 percent red mangrove. Petitioner proposes to implement an open marsh mosquito control management program consisting of the elimination of natural accumulations of water in low lying areas within the impoundment by rotary ditching small channels to allow these areas to drain and to allow predator fish access to the areas. Petitioner will remove exotic plant species throughout the impoundment and will revegetate with native species such as red, black, and white mangroves. Petitioner proposes to monitor the project area to assure that exotic plant species do not re-colonize. The mosquito impoundment area and the associated berms is estimated as being approximately 105 acres. Because of the difficulty in determining the mean high water line and because of the number of breaches in the berms, the precise acreage within the impoundment area that is not currently sovereign lands was not established. If accurately surveyed, it is possible that the amount of acreage within the impoundment owned by Petitioner may be determined to be up to 10 percent less than is currently estimated. For the purposes of this proceeding, it is found that 105 acres is a reasonable estimate of the area of the impoundment owned by Petitioner. After completion of the enhancement program, Petitioner proposes to donate all the property it owns within the impoundment to the State of Florida. Petitioner asserts that it would have the right to construct single family docks from its property directly into the Indian River if this project is not permitted and that these docks would not be subject to Respondent's permitting jurisdiction. The construction of such docks would have an adverse impact on manatees and seagrasses. As part of its mitigation plan, Petitioner offers to waive its right to construct single family docks from its property directly into the Indian River. EVALUATION OF THE MITIGATION PLAN The wetland in the existing impoundment area is presently a good biological system that contains a good diversity of plants and animals. While Petitioner's proposals will enhance this area, the evaluation of that enhancement should take into consideration the quality of the existing system. There are at least three existing breaches in the berm system. Through these breaches there is some tidal influences and the export of detrital material. Because of the relatively isolated nature of the mosquito impoundment, it currently contributes little to the productivity of the Indian River. The removal of the berm system will result in greater tidal influence in the impoundment area. As a consequence, much of the leaf litter from mangroves within the impoundment that presently accumulates on site would be exported as detrital material to the Indian River, which will add material to the food chain. It is expected that increased tidal influence will also result in an improvement in the dissolved oxygen levels within the impoundment. The reestablishment of tidal influence within the impoundment area will increase habitat for fish, shrimp, and crabs, and therefore benefit the Indian River. Removal of the impoundment berms to reestablish tidal influences within the impoundment area will increase and improve feeding and forage habitat for wading birds. Consequently, wading birds that nest in the vicinity of the project will be benefited. Increased tidal influence will likely result in better growth for mangroves which would create roosting sites for wading birds where none presently exist. Currently, Australian pines are the dominate species in areas within the impoundment area. Other areas of the impoundment are heavily populated by Brazilian pepper. Australian pines and Brazilian peppers do not serve as food sources for any native wildlife and have the potential to crowd out native plant species such as mangroves. If not removed, the potential exists for Brazilian pepper to become the dominate plant species. Removal of exotics and replanting with native species is a benefit to the Indian River system. With an appropriate monitoring plan, the exotic removal should be successful. If the project is permitted, the implementation of an appropriate monitoring plan should be a condition of the permit. Because of widespread mosquito control activities, the high marsh ecosystem is now rare in the Indian River system. The restoration of the impoundment area to an area of high marsh would be of benefit to the Indian River ecosystem. Prior to alteration by man, the mosquito impoundment was a high marsh ecosystem consisting primarily of black and white mangroves over an understory of succulent plants. There was a conflict in the evidence as to whether the Petitioner's proposals would result in the impoundment area returning to a high marsh area. While the impoundment area will be enhanced by the Petitioner's proposals, it is found that whether the area will be returned to a high marsh system is speculative. The mosquito impoundment is breached in various locations and, as a consequence, the impoundment is not functioning to control mosquitoes as it was originally designed. The current primary mechanism for mosquito control within the breached mosquito impoundment is aerial spraying of insecticides. The proposed removal of the existing berms will not adversely affect mosquito control and may positively affect mosquito control due to the increased accessibility of the impoundment by natural predators such as fish. This open marsh management plan is an effective means of controlling mosquitoes. The wetland creation proposed by Petitioner should have a high rate of success. Petitioner has agreed to implement a suitable monitoring plan to further guarantee the success of the proposal. If the project is permitted, the implementation of a suitable monitoring plan should be a condition of the permit. Scraping down the mosquito berms will create more wetlands, but the earth from the berms will be placed in the adjacent ditches, which presently serve as valuable tidal creek type habitat. Therefore, the mitigation itself will have some adverse impact. Petitioner's unspecified proposal to put in some rotary ditches to offset the loss of tidal creek habitat is inadequate in that there has been no specific proposal as to the location, size, shape, configuration, or acreage of the proposed rotary ditches. While planting of the littoral zones on the edges of the canal with Spartina provides some biological value, the growth of Spartina on the ten foot ledge on the east side will be impacted by boats and docks. The littoral zones will likely perform valuable wetland functions if properly planted and monitored and will likely become a productive wetland system that will provide habitat for wading birds. If the project is permitted, the Petitioner should be required to monitor the Spartina planting to ensure its successful growth. Even if the creation of the 13.9 acres of wetlands is successful, it will take years to become a mature biological system similar to the wetlands they are to replace. This time lag should be taken into account when evaluating the mitigation plan. There are adverse impacts from this proposed project that the mitigation plan does not offset. The mitigation plan does not offset the elimination of seagrasses, the loss of the Boot Lake habitat, the potential adverse impacts to shellfish and shellfishing, or the impacts to manatees. It is likely that property owners wishing to construct docks directly into the Indian River would have to get a permit from Respondent to gain access to the parts of the property where these docks could be constructed. Any proposal to extend docks into the Pelican Island National Wildlife Refuge would likely be prevented by the U.S. Fish and Wildlife Service. Whether such docks would, or could, be constructed is speculative, and this portion of the mitigation plan should be accorded little weight. As part of its mitigation plan, Petitioner proposes to donate approximately 105 acres to the State of Florida. This is considered to be a favorable aspect of the mitigation plan. The central issue in this proceeding is whether the mitigation plan offsets the negative impacts of this project so that the project becomes "clearly in the public interest." This issue is resolved by finding that even when the mitigation plan and the conditions that are recommended herein are considered, this project is "not clearly in the public interest."
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Respondent enter a final order that adopts the findings of fact and conclusions of law contained herein and which denies the modified application for the subject project. DONE AND ENTERED this 31st day of August 1994, in Tallahassee, Leon County, Florida. CLAUDE B. ARRINGTON 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 31st day of August, 1994.
The Issue Whether Michael Chbat's 2008 application for a Wetland Resource Permit (WRP) to construct a culvert extension across his property in Walton County, Florida, should be approved?
Findings Of Fact La Grange Bayou Estates La Grange Bayou Estates is a residential subdivision in Freeport, Walton County, Florida. The subdivision lies to the north of the shoreline of Choctawhatchee Bay. It can be viewed as divided roughly in half between bayfront lots south of an east-west road that transects the subdivision and lots that are north of the road. The subdivision is platted and the plat is in the public records of Walton County. Filed with the Clerk of the Circuit Court in and for Walton County, Florida, on September 15, 1982, the plat ("the 1982 Plat") shows 29 residential lots in the subdivision as of that date. See Petitioner's Ex. 6. Lots 1 through 16, according to the 1982 Plat, are the bayfront lots, south of a 40-foot wide road designated as a private road in the plat. That road is now known as Alden Lane. Wetlands over which the Department has jurisdiction ("jurisdictional wetlands") comprise much of the southern portion of bayfront lots and the drainage easement. Among the bayfront lots are both Lot 9 which belongs to Mr. Chbat and Lot 8 which belongs to Mr. Sheehey. A 50-foot easement lies between Lot 9 and Lot 8 and is described more fully below. The presence of jurisdictional wetlands on Mr. Chbat's lot over which he hopes to install the culvert extension requires that he obtain a WRP. To the north of Alden Lane are lots numbered by the 1982 Plat as 17 through 29. The lots are served by Alden Lane and, in what is roughly the northeast quadrant of the subdivision, by two other roads. One of the roads is shown on the 1982 Plat as a "40' PRIVATE ROAD." Id. A 2006 aerial photograph introduced into evidence by Chbat designates the road "unnamed." See Chbat Ex. 5. The other is designated as a "graded county road," on the 1982 Plat. By 2006, it had come to be known as Beatrice Point Road. Id. Beatrice Point Road transects a pond that runs roughly 340 feet (excluding about 30 feet of roadway) in a northeasterly direction from Alden Lane to the southern edge of an area north of the subdivision shown on the 1982 Plat to be un-platted. The pond is most likely the result of a "borrow pit" dug in order to obtain fill for the construction of the roads when the subdivision was initially developed. The southern boundary of the pond lies along approximately 140 feet of Alden Lane's northern edge. The pond is across the street from Lots 9, 10 and 11 of the subdivision. The pond is also not far northeast of the 50-foot easement (the "Drainage Easement") between Lots 9 and 8. The Drainage Easement The Drainage Easement is just to the west of Lot 9. It is noted on the 1982 Plat as a "50' EASEMENT (PRIVATE)." Id. The 50-foot wide Drainage Easement runs the length of the western boundary of Lot 9 and the length of the eastern boundary of Lot 8. The northeast corner of the Drainage Easement is approximately 30 feet from the southwest corner of the pond separated from the pond by the roadway of Alden Lane. The eastern boundary of the Drainage Easement is 226.37 feet in length, or if taken to the middle of Alden Lane, 246.3 feet. The western boundary is 206.13 feet long or if taken to the middle of the road, 226.65 feet. The purpose of the Drainage Easement, as is evident from its denomination in this recommended order, is drainage. As Mr. Street definitively put it at hearing, it is "now and always has been intended to drain stormwater to the [B]ay." Tr. Vol. III at 179. Mr. Street's opinion of the function of the Drainage Easement is supported by drawings submitted by Mr. Chbat as part of the WRP application. The drawings show that the Drainage Easement's function is facilitated by three culverts north of the Easement (referred to during the hearing as "pipes") each of which is intended to direct stormwater at its point of discharge toward the Drainage Easement. See Chbat Ex. 1. One of the culverts ("the Drainage Ditch Culvert") serves a drainage ditch that is to the north of the Easement and Alden Lane. According to the drawings, the drainage ditch lies on the other side of the "un-named road" from the pond, that is, to the west of the pond, and is some 40-to-50 feet north of the Drainage Easement. The Drainage Ditch Culvert extends from the ditch to the southern half of Alden Lane from where it appears from the application's drawings that stormwater would be conveyed to the western side of the Drainage Easement along it's border with Lot 8 and on toward the Bay. In fact, it is a functioning culvert that "conveys water from a swale on the side of the road into the [D]rainage [E]asement." Tr. 64. Once in the Drainage Easement, according to the drawings, the water should flow into the Bay out of a "cut," id., that is labeled on the drawings as an "existing trench." See Chbat Ex. 1. The trench, however, has been filled in with sand by tidal activity or sediment deposited by stormwater or both. The trench has not been maintained, and it no longer exists. The other two culverts (the "Pond Culverts") lie east of the Drainage Ditch Culvert. They catch overflow from the pond caused by stormwater and convey it under and through Alden Lane toward the Drainage Easement. The westernmost Pond Culvert (the "Western Pond Culvert") appears to terminate in Alden Lane near its southern edge just north of the Easement. At the time of hearing, however, it was not functioning properly. "[I]t is full of sand and silted up . . .", tr. Vol. I at 58; "[t]he pipe to the west is clogged and it is not functioning." Tr. Vol. I at 64. It is also at an elevation that would keep it from serving drainage purposes in all but the most severe storm events. See Chbat Ex. 9 at 22. The other Pond Culvert, (the "Eastern Pond Culvert") terminates in the northwest corner of Lot 9 at the border between Lot 9 and the Drainage Easement about 10 feet southeast of the terminus of the Western Pond Culvert. The Eastern Pond Culvert is the culvert with which the Amended Permit is concerned, that is, it is the culvert to be extended by the permit. Calling it a "pipe," Mr. Street offered the following about the assistance the Eastern Pond Culvert offers in conveying stormwater into the Drainage Easement and down to the Bay: There is currently a pipe that discharges into that easement. There . . . was an attempt to place the water from the . . . pond into the easement. And the natural flow of water on this entire property from the road to the [B]ay is north to south. At some point, at least 2004, that drainage easement contained a conveyance at its southern end that would safely discharge stormwater to the [B]ay. Tr. Vol. III at 179-80. Petitioner Sheehey and Lot 8 Thomas Sheehey is the owner of Lot 8, where he has a residence in which he makes his home. He has lived in the residence approximately five years. During that time, Mr. Sheehey has fished in the Bay and enjoyed the use of his kayak and his waverunner on the Bay. He also enjoys "sitting down having a cup of coffee and looking at it," tr. vol. III at 151, as well as watching his neighbors fish. The recreational uses to which he puts the Bay is the reason he chose to purchase a bayfront lot in La Grange Bayou Estates. Over the period of time that he has resided on Lot 8, Mr. Sheehey has observed the effects of rain events on his lot and well as lots close to Lot 8. He has also taken pictures of his property and the near-by lots. Among the photographs were four taken after rain events or "after a wet period," tr. vol. III at 88, at some point in the last four years. The four photos were introduced as a composite exhibit, Petitioner's Ex. 2, with each photograph marked as 2A, 2B, 2C or 2D. Mr. Sheehey could not specify when the pictures were taken in the past four years other than that if a picture had a certain dock in it, then it was taken after January of 2009. Petitioner's Ex. 2A was taken from Mr. Sheehey's lot looking toward the Bay. It shows an area of the lot under water separated from the Bay by a ridge. Petitioner's Ex. 2B is a picture taken from Lot 13 looking west across Lots 12, 11, 10, 9 "down through 8." Tr. Vol. III at 86. Much of what is photographed is among trees and vegetation emerging from water standing above the surface of the soil. Petitioner's Ex. 2C is a picture taken from Alden Lane looking south across Mr. Chbat's property. It shows a wide swath of water that extends from the road across most of the property to the Bay. The water is either in a swale or constitutes overflow outside the swale. The most recent of the four is Petitioner's Ex. 2D, which shows the dock referred to by Mr. Sheehey that was built in early 2009. It is a picture taken from Lot number 13 toward the west through Lots 12, 11, 10, 9. Like the others, it shows vegetation standing in water to the north of the Bay. Taken together, the four pictures in Petitioner's Exhibit 2 demonstrate that significant portions of the lots depicted are under water following sufficient amounts of recent rain. The four photographs that comprise Petitioner's Exhibit 2 are not the only photos taken by Mr. Sheehey that were introduced into evidence. Three other photographs of Mr. Sheehey's, Petitioner's Exhibits 7A, 7B and 7C, were admitted following testimony about them from a long-time observer of the flow of water from Alden Lane to the Bay. A Long-time Observer Thomas Eugene Cummins had lived in La Grange Estates "[t]wo months shy of 20 years," tr. vol. III at 7, at the time of his testimony. His house was the fourth to be constructed in the subdivision. Over the two decades of his residence, the pond between Alden Lane and the property north of the subdivision has been in existence. Consistent with the drawings submitted to DEP as part of the application, when asked where the pond overflows today, Mr. Cummins answered "it drains under Alden Lane on to Mr. Chbat's lot." Tr. Vol. III at 8. Asked by Mr. Chesser at hearing, "When the water comes out of the pond, is it possible to know where it spreads?"1/ Mr. Cummins testified: On really heavy rains, I have watched the normal color of the pond change from its dark blackish gray color into the reddish color that the clay has washed down into it, flow under Alden Lane and on to Mr. Chbat's lot, and then proceed west through the wetland on lots eight, seven, six, and my five, and turn reddish color even in my lot. Tr. Vol. III at 9-10. Mr. Cummins knew the source of the "red color" of the stormwater: red clay introduced to La Grange Estates by the County half a decade earlier. Mr. Cummins testified: Beatrice Point Road, which is the road that runs over the pond, about five years ago the county did some repair on the road and actually put red clay in certain spots to even it out. Tr. Vol. III at 9. Prior to the county's work on the road referred-to by Mr. Cummins, there had been no red clay in the neighborhood. Alden Way, for example, has no red clay. It is a road composed of shell. The only red clay in the subdivision is that which is on Beatrice Point Road. The water that runs onto Mr. Cummins' lot following a heavy rain rises to as much as 12 inches.2/ The water rises as high as it does because it is held back by a naturally-occurring land formation between the Bay and Mr. Cummins property. This geo-formation was referred-to at hearing as the ridge line or the ridge. The Ridge The Ridge was described by Mr. Cummins as a vegetated mass of earth that most of the time, even in heavy rains, sits above the water that collects on the bayfront lots of La Grange Estates. The Ridge prevents a substantial amount of stormwater runoff from entering the Bay from the wetlands on the southern portion of the subdivision's bayfront lots. For that reason, the ridge is called "our upland,3/" tr. vol. III at 13, according to Mr. Cummins. Between Lot 9 and Lot 5, the ridge varies in width "anywhere between 10 feet . . . up toward Mr. Chbat's lot, down to [Mr. Cummins'] lot where its around 30 or 40 feet [wide.]" Id. (It may extend, in fact, across all of the bayfront lots.) The ridge meanders not far from the shoreline. Id. In some places it is as narrow as five feet. The height of the ridge varies as well from as low as one foot to as high as two and half feet. Mr. Street also testified about the Ridge, referring to it in his testimony as a "ridge line": Now, there is a ridge line, and there's been a lot of testimony about this ridge line, that it exists across all of the lots. My testimony was, essentially, related to the review that I did, which was primarily associated with lots eight and nine, and the drainage easement between them. And from what I can tell, the elevation of that ridge line is give or take three. Elevation three, not a height of three. An elevation of three. It could be lower, and perhaps, is higher. And its subject to the vagaries of a number of factors, flow of stormwater, wave action, tidal influence, and the like. And these accretions and depositions of sand over time change that ridge line. And sometimes, it opens up. And sometimes it may not have a natural opening, depending on where you are along that entire stretch of beach. * * * [T]o the extent there is an opening in that ridge line, water will flow naturally to the bay. Tr. Vol. III at 180-181. An "east west flow of water," tr. vol. III at 181, along the bayfront lots, that is, a flow of water either in an easterly direction or a westerly one is contrary to the flow from Alden Lane north of the lots to the Bay south of the lots. Whether flowing east or west, the water in the southern portions of the bayfront lots is "controlled by the ridge line." Id. In other words, stormwater that flows from north to south across the bayfront lots, including Mr. Chbat's and the Drainage Easement, is going to collect and begin to flow from east to west or west to east at some point north of the Ridge before it drains into the Bay. The only exception to east-west flow, as made clear by Mr. Street, is when and if there is an opening in the Ridge that allows the water otherwise held back by the Ridge to flow southward into the Bay. The east-west flow of the water along the Ridge was described at hearing as "unnatural." Id. In fact, it is not un-natural. The Ridge is the cause of the east-west flow and, as Mr. Street testified, the Ridge is the result of natural processes such as tidal influence, wave action, accretion and deposition of sand.4/ The Ridge is shown in Petitioner's Exhibit 7A,5/ another photograph taken by Mr. Sheehey. The ridge as shown in the picture is well vegetated and above water to its north and higher than the Bay to its south. It is quite clear that if there is no opening in the ridge to the Bay, stormwater north of the ridge is forced to flow in east-west directions and is prevented from flowing into the Bay. Petitioners' Exhibit 7B is a photograph of the southern terminus of a swale (see paragraphs 40 - 49, below) on Mr. Chbat's property. It shows the swale cut through the Ridge. Water, however, does not appear to be running from the end of the swale into the bay. It appears that the end of the swale is a few feet from the Bay separated by a narrow sandy area on the shore. Nonetheless, the photograph shows that there is potential for stormwater to flow from the swale when the swale has more water in it. Petitioner's Exhibit 7C is a picture of the pond6/ across the street from Mr. Chbat's Lot 9. Mr. Chbat and Lot 9 Michael Chbat is the owner of Lot 9. He purchased the lot "[t]o build a house on it." Tr. Vol. I at 22. Because he has family close by (in Fort Walton Beach), Mr. Chbat expects to use a house built on the lot for weekend visits. His ultimate aspiration is to live in a house on Lot 9 after he retires from his position as a construction engineer with the City of Tallahassee. At hearing, Mr. Chbat described Lot 9 on the day he bought it: "the lot was overgrown. It drained from north to south. It had water standing on it. And it had a pipe [the Eastern Pond Culvert] on the northwest corner discharging." Tr. Vol. I at 23. He also described the state of the lot at the time of hearing. The Eastern Pond Culvert on the northwest corner was still there. The lot had been cleared to some extent to rid it of invasive species. Overgrown vegetation was trimmed or cleared to make room for a driveway permitted by the Department and "a parking pad in the front area of it, as well as an access pad in the uplands." Id. A dock had also been constructed from the property into the Bay. The most significant difference between the lot at the time of purchase and the lot at the time of hearing for purposes of this proceeding is that the lot now has a swale (the Swale) that runs from the point of discharge of the Eastern Pond Culvert "all of the way to the bay area." Id. The Swale The Swale was put in sometime after March 20, 2007, as the result of a Settlement Agreement fully executed on that date "By and Between Michael Chbat and Thomas L. Sheehey." Petitioner's Ex. 10. The Settlement Agreement followed events that commenced in 2004 when Mr. Chbat filed an application (the "2004 Application") with DEP for a WRP primarily to construct a house and a boardwalk leading from the house on Lot 9 to a dock in the Bay. The 2004 Application also proposed the extension of the Eastern Pond Culvert with a "pipe" along the western boundary of Chbat's property in a manner substantially similar to the culvert extension allowed by the Amended Permit that is the subject of this proceeding. On October 28, 2005, DEP proposed that the 2004 Application be granted. The permit (the "Proposed Original Permit") was assigned No. 66-0235320-001-DF. See Petitioner's Ex. 10, at 2. The Proposed Original Permit was challenged by Mr. Sheehey when he "filed a Petition for Administrative Hearing contesting certain action authorized under the [Proposed Original] Permit . . . specifically the relocation of a drainage pipe . . . ." Petitioner's Ex. 10, at 2. After referral of the petition to DOAH, Mr. Chbat and Mr. Sheehey wrote in the Settlement Agreement that they had "determined that it is in their best interests to settle this matter amicably pursuant to the terms hereafter". Id. Among the terms is that Chbat would file an Amended Application. See id. The agreed-to amendment to the 2004 Application was attached to the Settlement Agreement as Exhibit "A," a drawing of a "Drainage Swale Plan," produced by Genesis Group for Mr. Chbat. The drawing depicts a swale that runs from the discharge point of the Eastern Pond Culvert nearly the full length of the western boundary of Lot 9 to the Bay. See Exhibit "A" to Petitioner's Ex. 10. The Swale was designed to take the place of the 2004 Application's proposal for a "pipe"7/ attached to the point of the discharge from the Eastern Pond Culvert. The Settlement Agreement received the support of DEP because the Department believed that a swale would assist in improving the quality of the stormwater discharged to the Bay over the untreated discharge from the end of the "pipe." Pursuant to the terms of the Settlement Agreement the 2004 Application was amended. The Department amended the Proposed Original Permit accordingly and final agency action was taken with the issuance of a permit to Mr. Chbat (the "Final Original Permit") found in DEP Permit File No. 66-0235320-001- DF. Installation of the Swale The Swale was installed, but it did not work as intended. The result of the Swale's installation was more water on the lot rather than less. Mr. Chbat described the after-effects of the Swale: "it started bringing more water to the lot . . .". Tr. Vol. I at 31. The increased amount of water is the result of several factors, one of which is tidal influence: the tide from the Bay pushes water into the Swale. "[A]bout halfway on the swale . . . that water from the bay was meeting the water from the pipe . . .". Id. The water from the Bay tide and the stormwater conveyed by the Swale would meet at "about the middle of the span of the swale." Id. The result was "a lot more water," id., on the lot. Mr. Thomason confirmed Mr. Chbat's assessment that the reason the Swale did not function as effectively as necessary is tidal flow onto Lot 9 from the Bay particularly from high winds. But tidal flow onto Lot 9 and the interruption in the discharge of stormwater through the Swale are not the only problems. There is also a maintenance factor that accompanies tidal flow: sand deposition. Mr. Thomason elaborated: "[D]uring storm events or [just normal] wave action in the bay, sand is brought back up on to . . . the sandy area at the end of [Lot 9] next to the [Bay.]"8/ Tr. Vol. I at 62. The influx of sand onto Lot 9 is not just a problem for adequate functioning of the Swale. The Drainage Easement has "the same problem." Id. Both the Swale and the Drainage Easement are plagued by deposition of sand pushed landward by normal tidal influences and storm events. Maintenance of the Swale and the Drainage Easement, therefore, would assist the drainage of stormwater into the Bay. The tidal influence and maintenance issues that Mr. Chbat encountered with the Swale led him to apply for a different and new permit. That application was filed in 2008. The 2008 Application Mr. Chbat filed a "Joint Application for Works in the Waters of Florida" with DEP on August 1, 2008 (the "2008 Application"). See Chbat Exhibit 1. The work to be approved was similar to the work originally proposed in the 2004 Application in that both applications proposed installation of a "pipe" to be fixed to the discharge point of the Eastern Pond Culvert that would run along the western boundary of Lot 9 toward the Bay. A description of the work is contained in Section 10 of the 2008 Application: "Extension of an existing stormwater pipe within a private lot approximately 150 feet. The slope for the proposed pipe extension will be at minimum so that stormwater will be treated further, and minimizing erosion." Chbat Ex. 1 at 3. After the filing of the 2008 Application, Mr. Chbat learned that Mr. Sheehey objected to the newest Chbat proposal because he believed 150 feet is not lengthy enough to clear the Ridge. See Chbat Exhibit 2. In order to cure the objection, Mr. Chbat proposed a modification to the 2008 Application. He attached a "sealed and signed drawing," id., to a letter dated September 18, 2008, that he submitted to DEP. The drawing shows the extension to be 177 feet, 27 feet more than initially proposed by the 2008 Application. The additional 27 feet was intended to ensure that the discharge would be directly into the Bay in order to "eliminate any possible run-off impact to adjacent properties." Id. The modification was accepted by DEP." See exhibit number 19/ attached to the Amended Permit, Chbat Exhibit 4. There was conflicting evidence in the proceeding on whether the outfall from a culvert extension of 177 feet will be bayward of the Ridge. The issue was put to rest by Mr. Street’s testimony in rebuttal at the hearing. See Tr. Vol. III at 194 and 203-4. His testimony establishes that the point of discharge at the end of the culvert extension will clear the Ridge so that the discharge will be directly into the Bay. The Mound The culvert extension is designed at an elevation and with cover (presumably sod). The extension runs through jurisdictional wetlands and segments them. It does not, however, isolate any portion of the wetlands. The wetlands on Mr. Chbat's property and those to the immediate east and west of it, therefore, will retain their status as jurisdictional wetlands should the extension be installed. With its sod cover, the culvert extension will be a mini-berm (or a "mound" as Mr. Street called it) at an elevation of 17 to 18 inches above grade. Water that pools to its west will no longer be able to flow eastward of the mound (except rarely under the most extreme weather events.) Conversely, water that collects to its east will no longer be able to flow westward of the extension. It would have to be a severe storm event for water to rise above the mound. Mr. Chbat has never seen water rise to 18 inches above grade and Mr. Cummins testified the highest water ever gets on his property is roughly 12 inches. The Department approved the 2008 Application as modified to lengthen the extension to 177 feet and issued the Amended Permit. But an incorrect and critical assumption was made during review of the application that related to the mound. Review of the 2008 Application During his review of the application, Mr. Street, as DEP's stormwater engineer, assumed from the drawings that the Drainage Easement is functional.10/ The assumption was expressed in Mr. Street's testimony in the Department's case-in-chief: Q [D]id you determine whether the pipe, as it would be mounded . . . [the culvert extension covered in sod] . . . would create problems for storm water flow? A I looked at that. There were two conclusions that I drew. One was that the mound would create a higher water elevation on the Chbat property east of the mound, but would not create standing water west of the mound extending into the [Drainage E]asment . . . . Which on the drawings that I reviewed showed an existing trench at the south end of that easement. And it was my opinion that any water that fell west of the mound would exit through the easement. Tr. Vol. II at 92 (emphasis added.) Mr. Street's assumption that water would not pool to the west of the mound in the Drainage Easement and toward Mr. Sheehey's property was contradicted by Mr. Sheehey's stormwater engineer, Mr. Porterfield. THe Porterfield Testimony and Support for It at Hearing The testimony at hearing of Mr. Porterfield, who conducted a site visit, established the opposite of what Mr. Street assumed. The volume of stormwater runoff that pools east of the mound, that is, water on Lot 9, will not be as great as the volume as the water that pools west of the mound. Water that would have flowed onto Lot 9 from the Eastern Pond Culvert will flow directly to the Bay via the culvert extension. The extension will also protect the Drainage Easement and Lot 8 from water that would have flowed from the Eastern Pond Culvert onto that property. But there is a significant difference between stormwater to the west of the extension and to the east. To the extension's west, the Drainage Easement and Lot 8 will have to contend with stormwater from the Drainage Ditch Culvert, the culvert north of Alden Lane that does not convey stormwater from the pond but that like the Pond Culverts has a discharge point directed at the Drainage Easement. How often and to what extent pooling of stormwater will occur west of the mound due to its presence is difficult to determine on the state of this record.11/ No studies or analyses of the likelihood and severity of storm events and the volumes of stormwater runoff that would be produced by them were conducted by any of the stormwater engineers in the case nor were any such analyses done with regard to pooling caused by the presence of the covered culvert extension. The testimony of Mr. Porterfield, however, and other evidence, demonstrates that that additional collection of water west of the mound caused by the mound will occur following heavy rain. Mr. Street was present in the hearing room throughout the entire hearing, including during the presentation of Mr. Sheehey's case. As Mr. Street candidly testified on rebuttal after he had heard all the evidence: I would also maintain that the drainage easement which has signs of a historical usage as a drainage easement with a trench, in fact, that conveys water safely to the bay, that should be re-established and maintained. That’s what it’s there for.” Tr. Vol III at 181 (emphasis added.) Thus, it became clear to Mr. Street after listening to all the evidence in the case that the Drainage Easement has not been properly maintained. The trench that was expected to carry stormwater toward the Bay no longer exists. In short, the testimony of Mr. Street, for all his many strengths as a witness, falls short of supporting the position of the Department and Mr. Chbat. Having never visited the site,12/ he approved the project on the basis of drawings that do not conform to the on-site physical reality. When presented with the evidence at hearing that the Drainage Easement is not functioning, he championed re-establishment and maintenance of the Drainage Easement. Mr. Chbat placed part of the Swale's functionality problem on the tide pushing stormwater northward but his case also recognized the maintenance problem caused by deposition of sand that besets the Swale. Mr. Thomason, moreover, recognized that the Drainage Easement has the same maintenance issue. Mr. Chbat's stormwater engineer testified During storm events or just normal wave action in the bay, sand is brought back up on to. . . the sandy area at the end of [Chbat's] lot next to the water. And so that . . . tends to inhibit the natural flow down the swale . . . we have the same problem on the drainage easement . . . where sand builds up in that discharge. Tr. Vol. I at 62 (emphasis added). From this record, it is clear that neither the Swale nor the Drainage Easement functions properly. Their functional status, moreover, is due in significant part to lack of maintenance. It may be that maintenance ultimately will not solve the problem; maintenance efforts to keep the Swale and Drainage Easement clear of the sand deposited by tidal activity may require too much effort for them to be reasonably required. But that evidence was not produced. Indeed, the record was silent as to any maintenance efforts with regard to the Swale by Mr. Chbat or with regard to the Drainage Easement by the owner of the easement. The record is also silent as to whether DEP voiced any concern about the maintenance issues that beset the Swale. It is clear that concern was not raised by the Department in regard to the Drainage Easement until the rebuttal phase of the hearing, since the assumption was made that the easement was properly maintained. Whatever communication may have occurred with regard to maintenance issues among the parties, the Department issued the Amended Permit.13/ The Permit/Authorization Number for the Amended Permit is 66-235320-002-DF.14/ Issued December 19, 2008, the Amended Permit has an expiration date of December 19, 2013. The expiration date coincides with the construction phase of five years on the face of the Amended Permit. See Chbat Ex. 4. Mr. Sheehey Challenges the Amended Permit On January 6, 2009, Mr. Sheehey, pro se, filed with DEP a petition (the "Petition") seeking a formal administrative hearing with regard to "Amended Wetland Resource Permit 66- 00235320-002-DF." Although the Petition makes reference to the Amended Permit, it seeks in the first instance enforcement of the Settlement Agreement that relates to the Final Original Permit. The Petition states: "Petitioner believes that the Florida Department of Environmental Protection has jurisdiction over this matter and should enforce the March 20, 2007 Settlement Agreement which requires that Permittee act in conformance with Exhibit 'A' of the Agreement [the drawing of the Swale]." In the event that DEP declined to enforce the Settlement Agreement, the Petition sets out disputed issues of material fact that relate to issuance of the Amended Permit. The Petition was referred to DOAH on February 19, 2009. One week before the final hearing, the Department filed the motion in limine that is discussed in the Preliminary Statement of this Recommended Order. The motion was granted to the extent that it sought to preclude Sheehey from introducing evidence that supported enforcement of the Settlement Agreement since the 2008 Application, which, while bearing similarity to the 2004 Application, is nonetheless an independent application that should be approved or denied on its own merits without regard to the 2004 Application, the Proposed Original Permit, the Settlement Agreement or the Final Original Permit. The case proceeded to hearing on the remaining issues raised by the Petition: 1) whether Sheehey has standing to contest approval of the 2008 Application; 2) whether Chbat gave the notice required by Section 373.413, Florida Statutes, and 3) whether Chbat's application meets the criteria in statutes and rules for issuance of the Amended Permit. Standing The findings of fact relevant to Mr. Sheehey's standing are found in paragraph 9, above. Notice Notice of the 2008 Application was published in The Defuniak Springs Herald-Breeze, a newspaper published in Defuniak Springs, Walton County, Florida. The notice was published on October 23, 2008. The evidence presented by Mr. Sheehey concerning lack of legal notice consisted of testimony by Mr. Sheehey at hearing in response to questions from his counsel. See Tr. Vol. III at 134. The testimony does not establish that Mr. Sheehey was a person who had filed a written request for notification of any pending application affecting his particular area. The testimony of Mr. Sheehey, moreover, establishes that he was given oral notice of the application by Mr. O'Donnell within four days of its filing. WRP Permitting Criteria To obtain a WRP, an applicant must satisfy the criteria in Florida Administrative Code Chapter 62-312 and Section 373.414, Florida Statutes. These criteria govern a range of topics including water quality. Water Quality15/ Florida Administrative Code Rule 62-312.080 provides that no permit shall be issued unless the Department has been supplied with reasonable assurances that the proposed work will not violate water quality standards. Water that enters the pond spends some amount of time in the pond (residence time) before flowing out. During residence time, solids drop out of the water so that the quality of the stormwater that flows out of the pond is reasonably expected to be better than the quality of the stormwater runoff when it entered the pond. Vegetation surrounding the pond, furthermore, enhances the quality of the water in the pond, whether the water’s source is runoff or rain falling directly into the pond. The water that flows out of the pond north of Alden Lane is “existing discharge.” Tr. Vol. I at 65. It generally made its way to the Bay prior to the Swale. Some of it makes its way to the Bay via the Swale now; some of it outside the Swale as overflow. The culvert extension will convey that discharge to the Bay if the extension is installed. The quality of the water is not significantly less when it discharges to the Bay via the Swale or otherwise from the Chbat property than when it would enter the culvert extension should it be installed. It is true that the Swale would have provided filtration and additional treatment to the discharge from the Eastern Pond Culvert as does the Chbat property in general. But that does not mean that the quality of the culvert’s discharge is a concern. The Swale may have been an option preferable to the extension of the culvert as far as water quality goes but all parties agree that the Swale has failed as a conveyance (albeit Mr. Sheehey maintains that the Swale would work with proper maintenance.) That there is a discharge method that improves the quality of the discharge, such as a swale, does not mean that the discharge to the Bay via the culvert extension is of insufficient quality. None of the parties tested the quality of the discharge from the Eastern Pond Culvert. The Department, nonetheless, offered evidence with regard to its quality. The Department concluded that the quality of the pond and its discharge were not of concern. Had the pond been contaminated to an extent that would have given rise to concerns, moreover, the Swale or the culvert extension as a means of conveying the discharge to the Bay would not have made a “discernible difference.” Tr. Vol. II at 80. The Department provided evidence of assumptions made with regard to the quality of the water that led the Department to conclude that testing of the discharge was unnecessary. Mr. O’Donnell, the Department’s expert in the application of state rules and statutes in wetland resource permitting, detailed the assumptions at hearing: My assumption was that that pond was dug some time in the past as a way to provide fill for roads. That it was never any part of . . . [a] stormwater treatment system. And that it conveyed upstream water through the pond and then on down into Choctawhatchee Bay. It was strictly a [borrow pit and a conveyance pond.] It was never permitted as a treatment system in any way that I was aware of in my diligence [in determining whether the extension should be permitted.] Tr. Vol. II at 79. Once Mr. O’Donnell’s testimony entered the record at the behest of Mr. Chbat, the burden shifted to Mr. Sheehey to prove that the applicant had not provided reasonable assurance of water quality. Mr. Sheehey did not offer evidence of any testing of the discharge. Nor did he offer testimony that rebutted Mr. O’Donnell’s opinion. In fact, the testimony of Mr. Wilkinson (Mr.Sheehey's witness) supported Mr. O'Donnell's opinion with regard to water quality. See Tr. Vol. III at 112. In sum, the Department made assumptions that are found to be reasonable based on Mr. O’Donnell’s expertise and experience. Those assumptions were not shown to be unreasonable by Mr. Sheehey. The Department’s conclusions about water quality flow directly from Mr. O’Donnell’s reasonable assumptions. Reasonable assurances have been provided that the project will not violate water quality standards. Public Interest Test Choctawhatchee Bay is not designated as an “outstanding Florida water.” The test that Mr. Chbat must meet therefore is whether the activity proposed by the permit application is “not contrary to the public interest.” § 373.414, Fla. Stat. In making that determination, the Department is directed by the statute to consider and balance seven criteria. See § 373.414(a) 1-7, Fla. Stat. Of the seven, three are at issue once water quality is determined to be of no concern. Two of the three, “[w]hether the activity will be of a temporary or permanent nature,” Section 373.414(1)(a)5., Florida Statutes, and “[t]he current condition and relative value of functions being performed by areas affected by the proposed activity,” Section 373.414(1)(a)7., Florida Statutes, do not require in-depth consideration. With regard to the nature of the project time-wise, the evidence establishes that the culvert extension is intended to be permanent. With regard to current condition, the area affected by the proposed activity is a residential lot, a substantial portion of which is under water following heavy rain. To facilitate the conveyance of stormwater, the lot is served by the Swale. The Swale is not functioning optimally because of lack of maintenance and because of the Ridge. With regard to relative value from the standpoint of water quality, the function being performed by the lot and the Swale is little, at least as established by this record. While it is certainly true that the lot with or without the Swale will filtrate and otherwise treat stormwater runoff from the pond, the difference in the quality of the stormwater conveyed by the culvert extension from that which would enter the Bay without the extension is not significant. See the discussion above of Mr. O’Donnell’s accepted opinions. Of the seven statutory criteria to be weighed and balanced by the Department, the one that is central to this case is found in subparagraph 1., of subsection (1)(a): “[w]hether the [culvert extension] will adversely affect . . . the property of others.” The “property of others” in this case is the property of Mr. Sheehey. The Project’s Effect on the Property of Mr. Sheehey. For the reasons discussed in paragraphs 63-70, above, Mr. Chbat has failed to provide reasonable assurances that the project will not have a detrimental effect on the property of Mr. Sheehey. The extent of the detrimental effect to Mr. Sheehey's property is difficult to determine from this record but it is highly likely based on all the evidence of record that there will be a detrimental effect: additional flooding in heavy rain events.
Recommendation Based on the foregoing, it is recommended that the Department of Environmental Protection deny17/ the Amended Permit for the failure of Mr. Chbat to provide reasonable assurances that the project will not adversely affect Mr. Sheehey's property. DONE AND ENTERED this 14th day of January, 2010, in Tallahassee, Leon County, Florida. S DAVID M. MALONEY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 14th day of January, 2010.
Findings Of Fact The land here involved is located at the southern end of the Acme Improvement District. The northeastern portion of the tract is owned by Petitioner Leonard H. Tolley, and comprises some 15 percent of the total acreage of the tract. The remainder of the tract is owned by Petitioner Strazulla Brothers. The entire tract includes Sections 3 and 4, Township 455 Range 41E and a parcel of land in The Township 44 1/2 S Range 41E adjacent to Sections 3 and 4 and comprises some 1400 acres. The Strazulla property was acquired by Warranty Deed from the Trustees, Internal Improvement Trust Fund, by Philip Strazulla and subsequently conveyed to Petitioner. In 1978 real property taxes on the Strazulla property here involved was $17,453.42. The tract is bounded on the west by the L-40 levee and canal, on the north by Acme Improvement District Dike and C-27 Canal; on the east by property owned by Miller American Industries and on the south by property owned by the South Florida Water Management District. By this application Petitioner proposes to place levees with their borrow canals on the east and south sides of the tract and to construct a 240 acre reservoir adjacent to the L-40 levee by erecting a reservoir retention levee some 1400 feet eastward of the L-40 levee. By installing a 100,000 gallon per minute pump station at the southeast corner of the proposed reservoir, the water presently standing on the property could be drained allowing the eastern portion of the tract to be converted to agricultural use and the remainder converted into 2.5 acre residential sites. The 1972 Palm Beach County land use plan recommended the area here involved be zoned Preservation/Conservation, which effectively precluded development of the property. At that time, Strazulla attempted to sell the property or trade it to a governmental agency for property that could be developed, but without success. In 1978, the Palm Beach County Land Use Advisory Board changed the 1972 land use recommendation to Residential Estate to allow a reasonable use of the property. (Exhibit 7). The property abutting Petitioners' property to the north has been drained and thereon is located an orange grove and, west of the orange grove, 5- acre residential homesites. The property to the east is being developed as residential homesites. The property west of the C-40 canal comprises the Loxahatchee National Wildlife Refuge consisting of some 221 square miles of traditional Everglades wetlands. The property to the south is owned by the South Florida Water Management District and is of a character similar to Petitioners' property. Some two to three miles south of Petitioners' property is an east-west canal. In 1900 the property here involved was located in the eastern part of the Florida Everglades and received the sheet flow that characterized the natural Everglades. This historic hydroperiod has been disrupted by levees at Lake Okeechobee and by various drainage and irrigation canals constructed to render the large tracts of land thereby drained suitable for agriculture. In the immediate vicinity of the property, the L-40 levee and canal, which enclose the Loxahatchee National Wildlife Refuge (hereafter referred to as the conservation area) form a barrier to any sheet flow from this property onto the conservation area. This levee and canal bars practically all interchange of waters between Petitioners' property and the conservation area and is in the process of destroying part of the historical eastern boundary of the Everglades. Erection of the proposed levee on the east and south boundaries of the property would effectively stop the drainage now coming to this property from the east and the drainage from this property to the southeast. The South Florida Water Management District (SFWMD) owns a right-of- way to the east of the L-40 levee which is located in the area proposed by Petitioner for its reservoir. Petitioners' application to encroach on this right-of-way with the proposed reservoir was denied by SFWMD. This denial was based on the environmental impact, county zoning regulations (since changed) and the as yet undetermined effect of back pumping into the conservation areas. (Exhibit 17). Specifically, SFWMD Staff Report (Exhibit 17) found the environmental impact of the project will be: This proposed truck farming operation and residential development will destroy approximately 1100 acres of valuable wetland habitat by drainage. The impact on the 240 acres (60 acres of SFWMD right-of-way) of emergent marsh within the proposed reservoir will be determined by the water level management of the impoundment. A drastic change in water depth or inundation period could result in severe alterations of the present wetlands. An additional 50 acres of marsh will be lost due to dredge and fill operations for levee construction. The entire tract is poorly drained and is under water for considerable portions of the year, with the westernmost portion containing the longest periods and greatest depths of standing water. The soil in the eastern portion of the property is predominantly sandy, with a gray sandy loam layer at depths of 20 to 40 inches. The soil in the central portion of the tract is predominantly sandy, with a gray sandy loam layer at depths greater than 40 inches. The soil in the western portion of the tract is sandy, with a black organic surface layer (muck) 8 to 15 inches thick, underlain by gray sandy layers. Vegetation in the property goes from some pine and cypress in the eastern portion to sawgrass marshes in the western portion, with numerous varieties of plants associated with wet soil and marshy areas. During the proposed construction adequate safeguards can be imposed to prevent excess turbidity from entering State waters. This property comprises a large tract of pristine Everglades habitat for both plants and animals, and is of great value to the ecology of the state. In its undeveloped state it provides a buffer zone of up to two miles eastward for the conservation area. Water presently on the property is predominantly rainwater and of better quality than the water in the C-40 or C-27 canals adjacent to the property. Use of the land for agricultural purposes would increase the risk of water quality degradation caused by water runoff carrying fertilizers, herbicides and pesticides into the proposed reservoir and/or perimeter canals. If excess water on the property is pumped into the C-40 or C-27 canals, degradation of those waters could occur. The proposed development was opposed by the Florida Game and Fresh Water Fish Commission, not only because it would remove these fresh water marshes from the ecosystem and take away an essential habitat for birds and aquatic life, but also would remove a surface water retention basin and vegetation filtration of runoff from adjacent uplands. (Exhibit 16). The Permit Application Appraisal Report (Exhibit 15) which recommended denial of the application found the property acts as a buffer between the agricultural lands to the east and the conservation area and development as proposed would remove this buffer; and that water quality standards may be degraded due to agriculture runoff from the developed property being pumped into C-40 canal. Specifics of how runoff from property would be controlled were not obtained by the Environmental Specialist who prepared Exhibit 15. Pumping the surface waters on the property into a reservoir would reduce the diurnal variation in dissolved oxygen levels in the water and thereby improve water quality from that aspect. Water in the reservoir would be of greater depth than presently exists, thereby reducing photosynthesis and its concomitant benefits to the water quality. On the other hand, the greater depths could result in fewer grasses and more open surface water, thereby allowing more aeration of the water by wind action. Herbicides degrade fairly rapidly, and holding them in a reservoir would allow time to degrade. Many pesticides are water insoluble and would settle to the bottom of the reservoir.
