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.
The Issue The issue in this case was whether the Respondent, City of Cape Coral (City), was entitled to an Individual Environmental Resource Permit (Permit) that would allow removal of the Chiquita Boat Lock (Lock) and associated uplands, and installation of a 165-foot linear seawall in the South Spreader Waterway in Cape Coral, Florida.
Findings Of Fact Based on the parties' stipulations and the evidence adduced at the final hearing, the following findings of fact are made: The Parties The Department is the administrative agency of the State of Florida statutorily charged with, among other things, protecting Florida's water resources. As part of the Department's performance of these duties, it administers and enforces the provisions of chapter 373, part IV, Florida Statutes, and the rules promulgated thereunder in the Florida Administrative Code. Pursuant to that authority, the Department determines whether to issue or deny applications for environmental resource permits. The City is a Florida municipality in Lee County. The City is the applicant for the Permit allowing the removal of the Lock and installation of a seawall (Project). The Project is located within the geographic boundary of the City. The South Spreader Waterway is a perimeter canal separating the City's canal system from shoreline wetlands to the west and south, which run the length of Matlacha Pass to the mouth of the Caloosahatchee River at San Carlos Bay.1/ The Association is a Florida non-profit corporation that was created in 1981. The Association was created to safeguard the interests of its members. The Association has approximately 150 members who reside in Matlacha and Matlacha Isles, Florida. A substantial number of its members have substantial interests in the use and enjoyment of waters adjacent to and surrounding Matlacha. The Association's members were particularly interested in protecting the water quality of the surface waters in the area. Matlacha is an island community located to the northwest of Cape Coral, the South Spreader Waterway, and the Lock. Matlacha is located within Matlacha Pass Aquatic Preserve. Matlacha Pass is classified as a Class II waterbody designated for shellfish propagation or harvesting, and is an Outstanding Florida Water (OFW). See Fla. Admin. Code R. 62-02.400(17)(b)36; 62-302.700(9)(h). Petitioner, Karl Deigert, is a resident and property owner in Matlacha. Mr. Deigert is the president of the Association. Mr. Deigert’s house in Matlacha is waterfront. He holds a captain’s license and has a business in which he gives sightseeing and ecological tours by boat of the waters around Matlacha. He fishes in the waters around his property and enjoys the current water quality in the area. He is concerned that removal of the Lock would have negative effects on water quality and would negatively impact the viability of his business and his enjoyment of the waters surrounding Matlacha. Petitioner, Melanie Hoff, is a resident and property owner in St. James City. St. James City is located to the southwest of Cape Coral. Ms. Hoff’s property is located within five nautical miles of the Lock. Ms. Hoff engages in various water sports and fishes in the waters around her property. She moved to the area, in part, for the favorable water quality. She is concerned that removal of the Lock would negatively impact water quality and her ability to use and enjoy waters in the area. Petitioner, Robert S. Zarranz, is a resident and property owner in Cape Coral. Mr. Zarranz’s house in Cape Coral is waterfront. He is an avid fisherman and boater. He is concerned that removal of the Lock would negatively impact water quality, and that the quality of fishing in the area would decline as a result. Petitioner, Yolanda Olsen, is a resident and property owner in Cape Coral. Ms. Olsen’s house in Cape Coral is waterfront. She enjoys watersports and birdwatching in the areas around her property. She is concerned that removal of the Lock would negatively impact water quality, and that her ability to enjoy her property and the surrounding waters would suffer as a result. Petitioner, Jessica Blanks, is a resident and property owner in Cape Coral. Ms. Blanks’ house in Cape Coral is waterfront. She is concerned that removal of the Lock would negatively impact water quality, and that her ability to enjoy her property and the surrounding waters would suffer as a result. Petitioner, Joseph Michael Hannon, is a resident and property owner in Matlacha. Mr. Hannon is a member of the Association. He enjoys boating, fishing, and kayaking in the waters surrounding Matlacha. He is concerned that removal of the Lock would negatively impact water quality, and that his ability to enjoy his property and the surrounding waters would suffer as a result. Petitioner, Debra Hall, did not appear at the final hearing and no testimony was offered regarding her standing. The Project and Vicinity The Project site is 0.47 acres. At the Lock location, the South Spreader Waterway is 200 feet wide, and includes a 125-foot wide upland area secured by two seawalls, the 20-foot wide Lock, a 32-foot wide upland area secured by one seawall, and 23 feet of mangrove wetlands. The Lock is bordered to the north by property owned by Cape Harbour Marina, LLC, and bordered to the south by mangrove wetlands owned by the state of Florida. The 125-foot wide upland area and the 20-foot wide Lock form a barrier separating the South Spreader Waterway from the Caloosahatchee River. The preponderance of the competent substantial evidence established that the South Spreader Waterway behind the Lock is not tidally influenced, but would become tidally influenced upon removal of the Lock. Joint Exhibit 1 at p. 46. The City proposes to remove the Lock and one of the seawalls, reducing the 125-foot upland area to 20 feet. The proposed future condition of the area would include 125 feet of open canal directly connecting the South Spreader Waterway with the Caloosahatchee River. Joint Exhibit 1 at p. 47. The primary purpose of the Lock's removal is to alleviate safety concerns related to boater navigation. The Project's in-water construction includes demolition and removal of the existing Lock, removal of existing fill in the 125-foot upland area, removal of existing seawalls, and construction of replacement seawalls. The City would employ Best Management Practices (BMPs) throughout the course of the Project, including sediment and erosion controls such as turbidity barriers. The turbidity barriers would be made of a material in which manatees could not become entangled. All personnel involved with the Project would be instructed about the presence of manatees. Also, temporary signs concerning manatees would be posted prior to and during all in-water project activities. History of the South Spreader Waterway In the mid-1970's, the co-trustees of Gulf American Corporation, GAC Properties Credit, Inc., and GAC Properties, Inc., (collectively GAC) filed for after-the-fact permits from the Department's predecessor agency (DER), for the large dredge and fill work project that created the canal system in Cape Coral. In 1977, DER entered into CO 15 with GAC to create the North and South Spreader Waterways and retention control systems, including barriers. The Lock was one of the barriers created in response to CO 15. The Spreader Waterways were created to restore the natural hydrology of the area affected by GAC's unauthorized dredging and filling activity. The Spreader Waterways collected and retained surface runoff waters originating from the interior of Cape Coral's canal system. The South Spreader Waterway was not designed to meet water quality standards, but instead to collect surface runoff, then allow discharge of the excess waters collected over and through the mangrove wetlands located on the western and southern borders of the South Spreader Waterway. This fresh water flow was designed to mimic the historic sheet flow through the coastal fringe of mangroves and salt marshes of the Caloosahatchee River and Matlacha Pass estuaries. The fresh water slowly discharged over the coastal fringe until it finally mixed with the more saline waters of the estuaries. The estuarine environments located west and south of the Lock require certain levels of salinity to remain healthy ecosystems. Restoring and achieving certain salinity ranges was important to restoring and preserving the coastal fringe. In 1977 GAC finalized bankruptcy proceedings and executed CO 15. CO 15 required GAC to relinquish to the state of Florida the mangrove wetlands it owned on the western and southern borders of the South Spreader Waterway. This land grant was dedicated by a warranty deed executed in 1977 between GAC and the state of Florida. The Petitioners' expert, Kevin Erwin, worked as an environmental specialist for DER prior to and during the construction of the Spreader Waterways. Mr. Erwin was DER's main representative who worked with the GAC co-trustees to resolve the massive dredge and fill violation and design a system to restore the natural hydrology of the area. Mr. Erwin testified that the Lock was designed to assist in retention of fresh water in the South Spreader Waterway. The fresh water would be retained, slowed down, and allowed to slowly sheet flow over and through the coastal fringe. Mr. Erwin also testified that the South Spreader Waterway was not designed to allow direct tidal exchange with the Caloosahatchee River. In Mr. Erwin's opinion, the South Spreader Waterway appeared to be functioning today in the same manner as originally intended. Breaches and Exchange of Waters The Department's second amended notice of intent for the Project, stated that the Project was not expected to contribute to current water quality violations, because water in the South Spreader Waterway was already being exchanged with Matlacha Pass and the Caloosahatchee River through breaches and direct tidal flow. This second amended notice of intent removed all references to mitigation projects that would provide a net improvement in water quality as part of the regulatory basis for issuance of the permit. See Joint Exhibit 1 at pp. 326-333. The Department's witnesses testified that waters within the South Spreader Waterway currently mix with waters of the Caloosahatchee River when the Lock remains open during incoming and slack tides. A Department permit allowed the Lock to remain open during incoming and slack tides. Department witness, Megan Mills, the permitting program administrator, testified that she could not remember the exact date that permit was issued, but that it had been "a couple years." The location of breaches in the western and southern banks of the South Spreader Waterway was documented on another permit's drawings and pictures for a project titled "Cape Coral Spreader Waterway Restoration." See Cape Coral Ex. 9. Those documents located three breaches for repair and restoration identified as Breach 16A, Breach 16B, and Breach 20. The modeling reports and discussion that support the City's application showed these three breaches connect to Matlacha Pass Aquatic Preserve. Breach 20 was described as a connected tidal creek. Breach 16A and 16B were described as allowing water movement between Matlacha Pass and the South Spreader Waterway only when relatively high water elevations occurred in Matlacha Pass or in the South Spreader Waterway. The Department's water quality explanation of "mixing," was rather simplistic, and did not consider that the waterbody in which the Project would occur has three direct connections with an OFW that is a Class II waters designated for shellfish propagation or harvesting. Such a consideration would require the Department to determine whether to apply the OFW permitting standards, and the Class II waters permitting criteria in section 10.2.5 of the Environmental Resource Permit Applicant's Handbook, Volume I. See Fla. Admin Code R. 62-330.302(1)(a); 62-4.242(2); and 62-302.400(17)(b)36. The Caloosahatchee River, at its entrance to the South Spreader Waterway, is a Class III waters restricted for shellfish harvesting. The mouth of the Caloosahatchee River is San Carlos Bay, which is a Class II waters restricted for shellfish harvesting. There was no evidence that the Department's regulatory analysis considered that the waterbody in which the Project would occur directly connects to Class III waters that are restricted for shellfish harvesting, and is in close proximity to Class II waters that are restricted for shellfish harvesting. See Fla. Admin. Code R. 62-302.400(17)(b)36. and 62-330.302(1)(c).2/ Total Nitrogen The City's expert, Anthony Janicki, Ph.D., testified that nitrogen concentrations in the Caloosahatchee River were higher than in the South Spreader Waterway in the years 2017 and 2018. Thus, he opined that if the Lock is removed, water from the South Spreader Waterway would not negatively impact the Caloosahatchee River. However, the City's application was supported by an analysis, with more than a decade of monitoring data, which showed nitrogen concentration values were comparable inside the South Spreader Waterway and in the Caloosahatchee River. Dr. Janicki also used the Department's Hydrologic Simulation Program – FORTRAN (HSPF) watershed model to estimate the Total Nitrogen (TN) loading that would enter the Caloosahatchee River through the Chiquita Lock. Dr. Janicki estimated that TN loading to the Caloosahatchee River, after removal of the Chiquita Lock, would amount to 30,746 pounds per year. The Caloosahatchee River is listed as impaired for nutrients and has a TN Total Maximum Daily Load (TMDL) that was set by the Department in 2009. Dr. Janicki opined that removing the Lock would not result in adverse impacts to the surrounding environment. But the Petitioners obtained his concession that his opinion was dependent on the City's completion of additional water quality enhancement projects in the future as part of its obligations under the Caloosahatchee Estuary Basin Management Action Plan (BMAP) for achieving the TN TMDL. Dr. Janicki additionally testified that the potential TN loading to the Caloosahatchee River did not anticipate an actual impact to the River's water quality because the TN loads from the South Spreader Waterway were already factored into the 2009 TMDL. He essentially testified that the Lock's removal was anticipated and was factored into the model when the TMDL was established in 2009. Thus, the Petitioners proved by a preponderance of the competent and substantial evidence that the Department and the City were not aligned regarding how the City's application would provide reasonable assurances of meeting applicable water quality standards. The Petitioners proved by a preponderance of the competent and substantial evidence that the City relied on future projects to provide reasonable assurance that the removal of the Lock would not cause or contribute to violations of water quality standards in the Caloosahatchee River and the Matlacha Pass Aquatic Preserve. The Petitioners proved by a preponderance of the competent and substantial evidence that the Department relied on a simplistic exchange of waters to determine that removal of the Lock would not cause or contribute to violations of water quality standards in the Caloosahatchee River and the Matlacha Pass Aquatic Preserve. Water Quantity and Salinity The engineering report that supports the City's application stated that when the Lock is removed, the South Spreader Waterway behind the Lock will become tidally influenced. With the Lock removed, the volume of daily water fluxes for the South Spreader Waterway would increase from zero cubic meters per day to 63,645 cubic meters per day. At the location of Breach 20, with the Lock removed, the volume of daily water fluxes would drastically decrease from 49,644 cubic meters per day to eight cubic meters per day. Dr. Janicki testified that Breach 20 was connected to a remnant tidal creek that meanders and eventually empties into an embayment. The evidence demonstrated that the embayment is Punta Blanca Bay, which is part of the Matlacha Pass Aquatic Preserve. Dr. Janicki opined that Breach 20 was an area of erosion risk and sediment transport into downstream mangroves that would be significantly reduced by removing the Lock. He explained that the reductions in flow would result in reductions in velocities through Breach 20 and in the South Spreader Waterway itself. Mr. Erwin testified that Breach 20 was not a "breach."3/ He described it as the location of a perpendicular intersection of the South Spreader Waterway with a small tidal creek, which connected to a tidal pond further back in the mangroves. Mr. Erwin testified that an "engineered sandbag concrete structure" was built at the shallow opening to limit the amount of flow into and out of this tidal creek system. But it was also designed to make sure that the tidal creek system "continued to get some amount of water." As found above, Lock removal would drastically reduce the volume of daily water fluxes into and out of Breach 20's tidal creek system. Mr. Erwin also testified that any issues with velocities or erosion would be exemplified by bed lowering, siltation, and stressed mangroves. He persuasively testified, however, that there was no such evidence of erosion and there were "a lot of real healthy mangroves." Mr. Erwin opined that removal of the Lock would cause the South Spreader Waterway to go from a closed, mostly fresh water system, to a tidal saline system. He described the current salinity level in the South Spreader Waterway to be low enough to support low salinity vegetation and not high enough to support marine organisms like barnacles and oysters. The City's application actually supports this opinion. Using the Environmental Fluid Dynamics Code (EFDC) model developed by Dr. Janicki for this Lock removal project, comparisons were made describing the salinity distribution within the South Spreader Waterway. The model was run with and without the Lock, for both a wet and dry year. Dr. Janicki testified, and the model showed, that removal of the Lock would result in increased salinity above the Lock and decreased salinity downstream of the Lock. However, he generally opined that the distribution of salinities was well within the normal ranges seen in this area. The City's application also concluded that the resultant salinities did not fall outside the preferred salinity ranges for seagrasses, oysters, and a wide variety of fish taxa. However, Dr. Janicki did not address specific changes in vegetation and encroachment of marine organisms that would occur with the increase in salinity within the South Spreader Waterway. Secondary Impacts to the Mangrove Wetlands Mr. Erwin testified that the mangroves located on the western and southern borders of the South Spreader Waterway are currently in very good health. He additionally testified that loss of the current fresh water hydraulic head and an increase in salinity within the South Spreader Waterway would negatively impact the health of the mangrove wetlands. In addition, the City's application stated that removing the Lock would result in a drop in the water level of one to one and a half feet within the South Spreader Waterway. Mr. Erwin credibly and persuasively testified that a drop in water level of only a few inches would have negative effects on the health of mangroves, and that a drop of a foot could result in substantial mangrove die-off. Mr. Erwin testified that the mangrove wetlands adjacent to the South Spreader Waterway consist of a variety of plants and algae in addition to mangroves. He described the wetlands as a mangrove community made up of different types of mangroves, and epiphytic vegetation such as marine algae. This mangrove community provides habitat for a "wide range of invertebrates." He further testified that these plants and algae uptake and transform the nutrients that flow over and through the mangrove wetlands before they reach the receiving waters. Thus, the mangrove wetlands on the western and southern borders of the South Spreader Waterway serve to filter nutrients out of the water discharged from the Waterway before it reaches Matlacha Pass and the Caloosahatchee River. Mr. Erwin's credible and persuasive testimony was contrary to the City's contention that Lock removal would not result in adverse impacts to the mangrove wetlands adjacent to the South Spreader Waterway. The City and the Department failed to provide reasonable assurances that removing the Lock would not have adverse secondary impacts to the health of the mangrove wetlands community adjacent to the South Spreader Waterway. Impacts to Fish and Wildlife, Including Endangered and Threatened Species The Florida Fish and Wildlife Conservation Commission (FWC) reviewed the City's application and determined that if BMPs for in-water work were employed during construction, no significant adverse impacts on fish and wildlife were expected. For example, temporary signs concerning manatees would be posted prior to and during all in-water project activities, and all personnel would be instructed about the presence of manatees. The FWC determination only addressed direct impacts during in-water construction work. The City's application contained supporting material that identified the major change resulting from removal of the Lock that may influence fish and wildlife in the vicinity of the Project, was the opportunity for movement to or from the South Spreader Waterway canal system. Threatened and endangered species of concern in the area included the Florida manatee and the smalltooth sawfish. The City's application stated that literature review showed the smalltooth sawfish and the Florida manatee utilized non-main-stem habitats, such as sea-wall lined canals, off the Caloosahatchee River. The City cited studies from 2011 and 2013, which showed that non-main-stem habitats were important thermal refuges during the winter, and part of the overall nursery area for smalltooth sawfish. The City concluded that removal of the Lock "would not be adverse, and would instead result in increased areas of useable habitat by the species." However, the Petitioner's expert witness, John Cassani, who is the Calusa Waterkeeper, testified that there is a smalltooth sawfish exclusion zone downstream of the Lock. He testified that the exclusion zone is a pupping area for smalltooth sawfish, and that rapid salinity fluctuations could negatively impact their habitat. The City also concluded that any impacts to the Florida manatee would not be adverse, "and would instead result in increased areas of useable habitat by the species, as well as a reduction in risk of entrapment or crushing in a canal lock system." At the same time, the City acknowledged that "watercraft collision is a primary anthropogenic threat to manatees." The City's literature review included a regional assessment by FWC's Fish and Wildlife Research Institute (FWRI) from 2006. Overall, the FWRI report concluded that the mouth of the Caloosahatchee River, at San Carlos Bay, was a "hot spot" for boat traffic coinciding with the shift and dispersal of manatees from winter refugia. The result was a "high risk of manatee- motorboat collisions." In addition, testimony adduced at the hearing from an 18-year employee of Cape Harbour Marina, Mr. Frank Muto, was that Lock removal would result in novice boaters increasing their speed, ignoring the no-wake and slow-speed zones, and presenting "a bigger hazard than the [L]ock ever has." Boater Navigation Concerns Oliver Clarke was the City’s principal engineer during the application process, and signed the application as the City's authorized agent. Mr. Clarke testified that he has witnessed boater congestion at the Lock. He also testified that lack of boating experience and weather concerns can exacerbate the boater congestion issues at the Lock. Petitioners presented the testimony of Mr. Frank Muto, the general manager of Cape Harbour Marina. Mr. Muto has been at the Cape Harbour Marina for 18 years. The marina has 78 docks on three finger piers along with transient spots. The marina is not currently subject to tidal flows and its water depth is between six and a half and seven and a half feet. He testified that they currently have at least 28 boats that maintain a draft of between four and a half and six feet of water. If the water depth got below four feet, those customers would not want to remain at the marina. Mr. Muto further testified that the Lock was in place when the marina was built, and the marina and docks were designed for an area with no tidal flow. Mr. Muto also testified that he has witnessed several boating safety incidents in and around the Lock. He testified that he would attribute almost all of those incidents to novice boaters who lack knowledge of proper boating operations and locking procedures. Mr. Muto additionally testified that there is law enforcement presence at the Lock twenty-four hours a day, including FWC marine patrol and the City's marine patrol.

The final order deny Petitioners' request for an award of attorney's fees and costs. DONE AND ENTERED this 12th day of December, 2019, in Tallahassee, Leon County, Florida. S FRANCINE M. FFOLKES 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 12th day of December, 2019.
Findings Of Fact The Petitioner, E. F. Guyton, has filed an application for a permit which would allow the dredging of a boat slip and construction of a sedimentation basin with boat storage, specifically requiring the excavation of a boat basin, access canal, and access channel on his property which is located on the west shore of Crescent Lake, in Putnam County, Florida. The permit application number is 54-6806. The Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida which has the responsibility of appraising those applications such as the one submitted by the Petitioner, E. F. Guyton, and making a decision to grant or deny that permit. The authority for such action on the part of the Respondent resides in Chapters 253 and 403, Florida Statutes, and Rule 17, Florida Administrative Code. This cause comes on for consideration based upon the Respondent's letter of intent to deny the application, as dated August 22, 1978, after which the Petitioner has filed its petition challenging that intent to deny and requesting that the permit be granted. The petition in behalf of the Petitioner was received by the office of the Respondent on September 8, 1978. It was subsequently assigned to the Division of Administrative Hearings for consideration and that Notice of Assignment was dated September 28, 1978. The proposal for permit calls for excavation of a boat basin 100 feet wide and 480 feet long, leading into an access canal 25 feet wide and 500 feet long. This excavation is in the vicinity of an existing intermittent natural stream. The proposal would call for the removal of approximately 21,000 cubic yards of silt and sand, landward of mean high water. The excavation would be accomplished by use of a dragline to a depth of -2.0 feet MSL. The basin and canal slopes would be 2:1 and stabilization of slopes would be assured by riprap and grassing. A concrete spillway would be constructed at the upper end of the basin to direct the stream flow into the basin. In addition, the proposal calls for the dredging of an access channel through the shallow littoral zone of Crescent Lake to the mouth of the proposed access canal. The dredging involved with the access channel would cause the removal of 400 cubic yards of sediment from an area 250 feet long and as wide as 30 feet. The proposed depth of the channel is 2.0 feet MSL and slide slopes would be 5:1. The spoil would be pumped to a dike holding area on adjacent uplands. The Respondent's Exhibit No. 1, which is the permit application, offers a sketch of the boat basin with secondary sedimentation feature and the attendant access canal and channel. The project lies between U.S. Highway 17 and Crescent Lake, Areas to the south and west of the site are pasture and bayhead wetlands and they serve as a watershed for the aforementioned intermittent stream. Other upland areas in the vicinity are dominated by fully-drained flat woods and well-drained sand hill and messic oak terrain. The project site waterward of the mean high water is part of a shallow littoral zone of the west shore of Cresent Lake. The intermittent stream receives the runoff from the pastureland and drainage from U.S. Highway 17. There is a pronounced change in elevation during the course of the intermittent stream. The submerged littoral zone of the lake, which includes the proposed site of the access canal, falls away at a gentle slope and includes a number of supporting hardwoods, predominantly bald cypress. The area also includes submerged emergent vegetation, which is found in the shallows offshore. These shallows are exposed to favorable sunlight from the point of view of the health of this vegetation. The vegetation includes an emergent bed of oft stem bulrush (Sicrpus validus) which is in line with the proposed channel. Within the photic zone there is submerged tape grass (Valisneria americana) and naiad (Najas sp.). On the shore of Crescent Lake at the project site is found a hardwood swamp in its natural form, together with a creekbed which divides into numerous channels fanning out in the direction of the lake itself. This area of the creekbed contains bald cypress (Taxodium distichum), red maple (Acer rubrum), swamp ash (Fraxinus panciflora), black willow (Salix nigra), black gum (Nyssa biflra), water hickory (Carya aquatica), and wax myrtle (Myrica cerifera). The herbs and ferns in this area include penny wort (Hydrocotyl umbellata), arrow- arum (Peltandra virginica), leather fern (Acrostichum danaeifolium), and royal fern (Osmunda regalis). The sediments found in the creek area are sandy to silty sand. In the area where the boat basin/sedimentation facility would be located, the present intermittent stream is much more confined than in the area of the creekbed. Only in times of heavy rainfall does the water come outside the banks of the intermittent stream and inundate the surrounding territory. This portion of the stream is densely vegetated by a mixture of hydrophytes, facultative hydrophytes, an optimally situated upland species. These include sweet bay (Magnolia virginiana), black gum (Nyssa biflora), and red maple (Acer rubrum). Additionally, there are slash pine (Pinus elliotii), long leaf pine (Pinus palustris), dahoon (Ilex cassine), wax myrtle (Myrica cerifera), water oak (Quercus nigra), wild azalea (Ericaceae), and saw palmetto (Serenoa repens). The sedminets in this area range from very sandy in the slightly higher elevations adjacent to the stream bed to a heavy peat which is found predominantly in the bay tree locations. The uplands in the agricultural area are dominated by water oak, slash pine, long leaf pine, live oak and saw palmetto. A more graphic depiction of the project site and in particular as it relates to the intermittent stream, shore line upland agricultural area, and U.S. Highway 17 may be found in the Petitioner's Exhibits 1 and 2 and the Respondent's Exhibits 2 through 15, which are photographs of the project site. There are numerous varieties of fish in the area of Crescent Lake through which the access channel would be routed. These include: Seminole killifish (Fundulus seminolis), naked goby (Gobiosoma bosci), black bullhead (Ictalurus melas), brook silversides (Labidesthes sicculus), sunfish (Lepomis sp.), large-mouth bass (Micropterus salmoides) and Atlantic needlefish (Strongylura marina) . In addition, there are 35 species of invertebrates which were collected in the studies made by employees of the Respondent in their assessment of this permit application. The names of those invertebrates may be found in the Respondent's Exhibit No. 19 which was admitted into evidence in the course of the hearing. The vegetation and shallow water with a sandy bottom, together with the numbers and species of macro invertebrates, small fishes and immature game fishes point to the fact that this part of the lake serves as a valuable site for the propagation of fish, otherwise referred to as a spawning ground. The water quality in Crescent Lake at the site of the project is good, from the standpoint of gross observations. However, there have been some indications of eutrophication in Cresent Lake. A more complete understanding of the water quality may be gained from an examination of the Respondent's Exhibits 21 through 41 admitted into evidence. These exhibits are constituted of certain water quality reports rendered after extensive testing in Crescent Lake. The rainfall in the area exceeds 54 inches a year, with 50 percent of that rainfall being recorded in the wettest quarter, in which over 7 inches a month would fall. July has recorded 15 inches as a mean measurement over the last 80 years, with the month of May showing less than 2 inches, the month of September showing less than 2 inches and the month of October less than 1 inch. In considering the proposed project, a beginning point would be an examination of the ability of the primary filtration pond and secondary filtration function found in the boat basin, to adequately disperse the pollutants which will come into the system from the agricultural area and U.S. Highway 17. That treatment system is inadequate. The inadequacy exists because in periods of low rainfall the pollutants will settle to the bottom of the siltation system and will not be dispersed evenly. This cycle of low rainfall when followed by heavy rainfall, such as occurs in July, will cause the pollutants to be rapidly discharged from the system into the basin of the lake, either in a dissolved form or a free form, causing an unreasonable dilatorious effect to water quality and creating possible turbidity. The confined nature of the proposed channel which empties into the lake will promote scouring because the water is coming out in a more confined area than the natural access allows at present. In addition, the flow velocity in the secondary siltation system is not strong enough to flush out the pollutants in an efficient manner. Finally, channelization promoted by the system would remove a certain percentage of the biological treatment that occurs in the natural intermittent stream, thereby introducing a greater quantity of pollutants into the lake and reducing oxidation that this biological treatment and natural course of the intermittent stream bed now provides. The project, as contemplated, is very similar in its nature to the canal system in Dunns Creek, a body of water adjacent to Crescent Lake. A study conducted on that canal system revealed a very poor quality of dissolved oxygen, which falls below the water quality standards for Class III waters. (A copy of this report may be found as Respondent's Exhibit No. 20 admitted into evidence.) These are the same standards that would apply to Crescent Lake. In addition, there is a lack of flushing and the development of aquatic weeds deterimental to the fish and invertebrates located in the area of the Dunns Creek canals. Therefore, a similar problem could be expected in the project now under consideration. If the project were completed, the excavation of the material would cause disruption of the sediment and water quality degradation if precipitation occurred during the excavation. Efforts at turbidity control would not protect against a heavy rain and the maturely vegetated stream bed and productive littoral vegetation and substrates would be lost. The long term effects of the project would cause degradation of the water quality and a loss of fish and wildlife resources in the impact area. The filtrative assimilative capacity provided by the algae, shrubs, trees and associated substrates involved in the process of absorption and in aerobic bacterial metabolism, would be eliminated by the project and replaced by an intermittently flushed, highly nutrified shallow water lagoon and canal. Pollutants associated with boat operations would further compound the water quality problems and perpetual sediment disruption would occur because of a natural result of shallow water maintenance and use of the system. Siltation and periodic discharge of degraded basin water into the littoral zone of the lake would adversely effect the productive potential and the habitat potential offered by this area in its present form. Based upon a full assessment of the project, it is established that there would be increased and harmful erosion, shoaling of the channel and the creation of stagnant areas of water. It would also cause an interference with the conservation of fish, marine and wildlife to an extent that is contrary to the public interest. It would promote the destruction of natural marine habitats, grass flats suitable as nurseries or feeding grounds for marine life and established marine soils suitable for producing plant growth of a type useful as a nursery or feeding ground for marine life or natural shoreline processes to an extent contrary to the public interests. These failings are in direct contravention of Chapter 253, Florida Statutes. The project would be contrary to State Water Quality Standards, as developed pursuant to authority of Chapter 403, Florida Statutes. Thus, the Petitioner has failed to give reasonable assurances that the immediate and long term impacts of the project would not result in a violation of the State Water Quality Standards, as required by Rule 17-4.28(3), Florida Administrative Code.
Findings Of Fact The petitioner is a private landowner of a tract of land adjacent to the Suwannee River in Dixie County, Florida. The Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida charged with carrying out the mandates of Chapter 403, Florida Statutes, and the rules contained in the Florida Administrative Code promulgated thereunder. The Petitioner's proposed project entails the construction of a twelve- foot wide filled road across approximately 270 feet of swampy area in which the dominant plant species is bald cypress (taxodium distichum), a species listed in Rule 17-4.02(17), Florida Administrative Code. The property to be so developed by the petitioner lies within the landward extent of the Suwannee River in Dixie County. The Suwannee River, in this project area, constitutes waters of the state over which the Department has dredge and fill permitting jurisdiction pursuant to Rule 17-4.28(a), Florida Administrative Code. The project areas within "outstanding Florida waters" as defined in Rule 17-3.04(1)(3)g, Florida Administrative Code. The "upland berm" or river terrace on the property immediately adjacent to the navigable portion of the river is caused by the natural alluvial deposition of the river and the landward extent of the state waters here involved crosses the property in approximately the center of the parcel. The proposed filing for the road crossing the swamp would result in the permanent elimination of at least 3,240 square feet of area within the landward extent of the Suwannee River. Specifically, the project would consist of a road some 12 feet wide at the bottom and 8 feet wide at the top, extending approximately 270 feet across the swampy area in question from the portion of the property which fronts on a public road, to the river terrace or "berm" area along the navigable portion of the Suwannee River. The road will be constructed with approximately 450 cubic yards of clean fill material with culverts 12 feet in length and 3 feet in diameter placed under the road at 25 foot intervals. The parties have stipulated that the Department has jurisdiction pursuant to Chapter 403, Florida Statutes, and Public Law 92-500, to require a permit and water quality certification or the construction of a stationary installation within the waters of the state which this project has been stipulated to be. The area to be filled is primarily vegetated by bald cypress, ash, blackgum, planer trees and other swamp species falling within the definitional portion of the above rule. The swamp contributes to the maintenance of water quality in the river itself by the filtering of sediment and particulates, assimilating and transforming nutrients and other pollutants through the uptake action of the plant species growing therein. The proposed project would destroy by removal, and by the filling, a substantial number of these species on the site which perform this function. The swamp area also serves as a habitat, food source and breeding ground for various forms of fish and wildlife including a species of state concern, the yellow-crowned night heron, which has been observed on this site and which requires such habitat for breeding and for its food source (see the testimony of Kautz). The area in question provides flood protection by storing flood waters and releasing them in a gradual fashion to the river system, especially during dry periods when the river level is lower than that of the swamp which serves to augment stream flow in such periods. As established by witness Kautz, as well as witnesses Rector and Tyler, the filling proposed by the Petitioner would cause degradation of local water quality within the immediate area where the fill would be placed and, the attendant construction activity adjacent to either side of the filled area would disturb trees, animals and other local biota. The period during and immediately after the construction on the site would be characterized by excessive turbidity and resultant degradation of the water quality within the area and downstream of it. The long-term impact of the project would include continued turbidity adjacent to and downstream from the filled road due to sloughing off of the sides of the road caused by an excessively steep slope and to the necessary maintenance operations required to re-establish the road after washouts caused by each rain or rainy period. An additional long-term detrimental effect will be excessive nutrient enrichment expected in the area due to the removal of the filtrative functions caused by removal of the trees and other plant life across the entire width of the swamp and the resultant inability of the adjacent areas to take up the nutrient load formerly assimilated by the plant life on the project area. The project will thus permanently eradicate the subject area's filtrative and assimilative capacity for nutrients, heavy metals and other pollutants. The effect of this project, as well as the cumulative effect of many such already existent fill roads in this vicinity along the Suwannee River, and the effect of proliferation of such filling, will cause significant degradation of local water quality in violation of state standards. The effect of even this single filled road across the subject swamp is especially severe in terms of its "damming" effect (even with culverts). The resultant retention of water standing in the swamp for excessive periods of time will grossly alter the "hydro period" of the area or the length of time the area is alternately inundated with floodwaters or drained of them. This will cause a severe detrimental effect on various forms of plant and animal life and biological processes necessary to maintenance of adequate water quality in the swamp and in its discharge to the river itself. The excessive retention of floodwaters caused by this damming effect will ultimately result in the death of many of the tree species necessary for the uptake of nutrients and other pollutants which can only tolerate the naturally intermittent and brief flood periods. This permit is not necessary in order for the Petitioner to have access to his property as his parcel fronts on a public access road. The purpose of the proposed road is merely to provide access to the river terrace or "upland berm" area on the portion of the property immediately adjacent to the navigable waters of the Suwannee River. The Department advocated through its various witnesses that a viable and acceptable alternative would be the construction of a walkway or a bridge on pilings across the jurisdictional area in question connecting the two upland portions of Petitioner's property. Such a walkway would also require a permit, but the Department took the position that it would not object to the permitting of an elevated wooden walkway or bridge for vehicles. The petitioner, near the close of the hearing, ultimately agreed that construction of such a walkway or bridge would comport with his wishes and intentions for access to the river berm portion of his property and generally indicated that that approach would be acceptable to him. It should also be pointed out that access is readily available to the waterward portion of the property from the navigable waters of the river by boat. The Petitioner did not refute the evidence propounded by the Department's expert witnesses, but testified that he desired the fill-road alternative because he believed it to be somewhat less expensive than construction of an elevated wooden bridge or walkway and that he had been of the belief that the use of treated pilings for such a walkway or bridge would result in chemical pollution of the state waters in question. The expert testimony propounded by the Respondent, however, establishes that any leaching action of the chemical in treated pilings would have a negligible effect on any life forms in the subject state waters at any measurable distance from the pilings. In summary, the petitioner, although he did not stipulate to amend his petition to allow for construction of the bridge as opposed to the fill road, did not disagree with it as a viable solution and indicated willingness to effect establishment of access to the riverfront portion of his property by that alternative should it be permitted.
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 The issue is whether Respondent, Dames Point Workboats, LLC, is entitled to issuance of the Consolidated Environmental Resource Permit and Recommended Intent to Grant Sovereignty Submerged Lands Authorization, Permit No. 16-0345934-003-EI, as announced by Respondent, Department of Environmental Protection, in the Consolidated Notice of Intent to Issue Environmental Resource Permit and Lease to Use Sovereignty Submerged Lands issued on July 20, 2018, and subsequently amended on December 11, 2018.
Findings Of Fact The Parties Petitioner City is a consolidated municipality and county political subdivision of the State of Florida. The Project is located within the geographic boundary of the City. The City initiated this proceeding by filing its Verified Petition for Formal Administrative Hearing ("Petition") with DEP on August 17, 2018. Respondent Workboats is the applicant for the Project. Its business address is 5118 Heckscher Drive, Jacksonville, Florida 32226. Workboats' owner, Shafnacker, owns the property located upland of the sovereignty submerged lands on which the Project is proposed to be constructed and operated. Respondent DEP is the administrative agency of the State of Florida statutorily charged with, among other things, protecting Florida's water resources. As part of DEP's performance of these duties, it administers and enforces the provisions of chapter 373, part IV, Florida Statutes, and the rules adopted pursuant to those statutes. Pursuant to that authority, DEP determines whether to issue or deny applications for environmental resource permits. Pursuant to section 253.002, DEP also serves as staff to the Board of Trustees of the Internal Improvement Trust Fund ("Board of Trustees") and in that capacity, reviews and determines whether to issue or deny applications for sovereignty submerged lands leases. The Back Channel and Vicinity of the Project The Project is proposed to be located in the "Back Channel" area of the St. Johns River, directly across from Blount Island. The Back Channel, as a part of the St. Johns River, is classified as a Class III waterbody. It is not designated an Outstanding Florida Water, is not located within an Aquatic Preserve, and is not designated for Shellfish Propagation or Harvesting. The Back Channel is configured in the shape of an inverted "U" and runs between Blount Island and Heckscher Drive, from the southeast corner of Blount Island to the bridges located on the northwest side of Blount Island. It constitutes a portion of the historic main channel of the St. Johns River and was used for all vessel navigation in the river until the Dames Point Cut was dredged through a peninsula to the south, creating Blount Island and a new straight channel to the Atlantic Ocean. Most vessels, including large ships, use the Dames Point Cut for ingress into and egress from the St. Johns River. However, the Back Channel remains navigable and is used for recreational activities and some commercial and industrial navigation. A mix of residential, commercial, and industrial and land uses is located on the north shore of the Back Channel in the vicinity of the Project. These uses consist of approximately 90 single-family residences having docks, three fish camps/recreational marinas, two restaurants, and docking structures used for mooring inshore shrimping vessels. A docking facility owned by M & M Shrimp and used for mooring shrimping vessels is located on the Back Channel immediately to the west of the Project site. A residence owned by Wood is located on the Back Channel immediately east of the Project site. Four other residences are located immediately east of Wood's residence, and back up to the Back Channel. Most of the shoreline on which these residences are located consists of riprap; however, a small patch of salt marsh borders the shoreline on Wood's residential parcel. Although Blount Island is a heavy industrial port, its northern shoreline on the Back Channel, across from the proposed Project site, consists of relatively undisturbed salt marsh and trees. The northeastern shoreline of the Back Channel generally consists of salt marsh and riprap, with docks constructed along the shoreline. Two bridges connect Blount Island to the mainland a short distance west of the proposed Project. These bridges each have a clearance of approximately ten feet, so they cannot be cleared by large vessels. As a practical matter, this has the effect of limiting the size of vessels that use the Back Channel in the vicinity of the Project. The Back Channel west of the bridges to the southwestern tip of Blount Island is fronted by heavy industrial uses, and numerous multi-family residential and industrial docking facilities are located in this area. A slow speed, minimum wake zone for boat operations extends 300 feet out into the Back Channel from both the north and south shorelines. The Back Channel is approximately 1,340 feet wide at the point at which the Project is proposed to be constructed. The Proposed Project The proposed Project will be constructed and operated4/ as a commercial tugboat/work boats mooring and loading/ offloading facility. The Project is proposed to be constructed and operated on sovereignty submerged lands5/ and in surface waters subject to State of Florida regulatory jurisdiction. Therefore, an environmental resource permit and sovereignty submerged lands lease are required for construction and operation of the Project.6/ The Project will be located waterward of the mean high water line on sovereignty submerged lands adjacent to four upland waterfront parcels that are owned by Shafnacker. These lots are: Lot 6 (5100 Heckscher Drive, RE 159971 0000); Lot 7 (5110 Heckscher Drive, RE 159972 0000); Lot 8 (5118 Heckscher Drive, RE 159973 0000); and Lot 9 (5120 Heckscher Drive, RE 159974 0000). Collectively, these lots have approximately 425 feet of linear shoreline, as measured at the mean high water line, bordering the Back Channel. This shoreline is comprised of salt marsh and riprap. A substantial portion of lots 6, 7, and 8 consists of salt marsh wetlands. No structures are proposed to be constructed on Lot 6. The salt marsh areas on lots 7 and 8 are traversed by existing pile-supported piers/access docks. To the extent they are replaced, such replacement will be by like-for- like structures, so there will be no new impact to the salt marsh wetlands on these lots. Most of Lot 9 consists of upland, some of which is authorized to be refilled under the Consolidated Authorization. A small wetland area consisting of approximately 18 square feet of salt marsh will be crossed by a new dock, but will not be filled or otherwise physically impacted. Dock A is proposed to be located on sovereignty submerged lands waterward of Lot 7, and will consist of a 15.4-foot-long by 8-foot-wide extension added to the waterward end of an existing 150.8-foot-long by 8-foot-wide wooden dock, plus a 4-foot-long gangway attached to the waterward end of the extension, which will connect to a 100-foot-long by 9.5-foot wide concrete floating dock. Dock B is proposed to be located on sovereignty submerged lands waterward of Lot 8, and will consist of a 40-foot-long by 10.3-foot-wide concrete floating dock with an 18-foot-long by 6-foot-wide platform, and a 4-foot-long gangway attached to an existing 125.2-foot-long by 5-foot-wide wooden dock. Dock C is proposed to be located on Lot 9, and will consist of a new inverted-L-shaped dock consisting of a 71-foot- long by four-foot wide pile-supported finger dock extending perpendicular to the shoreline into the Lease area, and a 26-foot long by 4-foot-wide dock running roughly parallel to the shoreline that will be constructed outside of the Lease area. Four wooden pilings also are proposed to be installed waterward of Lot 9. Three of these pilings will be located along the eastern boundary of the Lease, and the piling closest to the shoreline of Lot 9 will be located outside of the Lease area. All of these pilings will be set back 25 feet from Workboats' eastern riparian rights line. The newly constructed piling-supported dock additions to docks A and B, and new Dock C, will be elevated four feet above the marsh and will be constructed by hand-laying planks from the shoreline outward into the water, using the previously- laid planks as support while laying the new planks. Three three-pile mooring dolphins also are proposed as part of the Project. They will be installed within the Lease area, set back 38 feet from the southern boundary. No dredging is proposed or authorized for the Project. The Lease will be issued for a term of ten years and will preempt approximately 49,746 square feet of sovereignty submerged lands. The western boundary of the Lease is located 25 feet east of the upland property's western riparian rights line, and the eastern boundary of the Lease is located 25 feet west of the upland property's eastern riparian rights line. With the exception of a portion of Dock C and one wood piling that will be constructed on submerged land owned by Shafnacker,7/ all other structures proposed as part of the Project will be constructed within the boundaries of the Lease, and all vessel mooring and over-water operational activities authorized as part of the Project will occur within the Lease area. The Consolidated Authorization authorizes the placement of approximately 3,500 square feet of fill landward of the mean high water line and the jurisdictional wetland line, to replace historic fill eroded by hurricanes in 2017. Additionally, as a condition of the Consolidated Authorization, Workboats is required to restore approximately 250 square feet of salt marsh cord grass waterward of the mean high water line on Lot 9 as corrective action for unauthorized filling/destruction of salt marsh wetlands. As noted above, when constructed, the Project will operate as a tugboat/work boats mooring and loading/unloading facility. Workboats owns a fleet of approximately 40 vessels, comprised of barges, tow/push boats, and work boats, which are used to provide a range of marine services to third parties, including the transport/delivery of food and other supplies; artificial reef placement; marine demolition; and pile driving. These vessels will be moored at the docks, mooring dolphins, and mooring piles comprising the Project.8/ Of these 40 vessels, 28 are barges that range from ten to 130 feet in length, and have drafts ranging from 1.5 to 7.5 feet deep. The remaining 12 vessels are boats that range from 14 to 46.2 feet in length, and have drafts ranging from one foot to 6.8 feet deep. The water depths within the Lease area range from one tenth of one foot immediately adjacent to the shoreline, to between 39.5 and 43.5 feet deep at mean low water at the southern boundary of the Lease. Only one or two of the smaller boats in Workboats' fleet have drafts that are shallow enough to enable them to moor on the shoreward sides of Docks A and B. In any event, all vessels must moor in areas within the Lease area having depths at mean low water sufficient to ensure that they do not come into contact with submerged resources. To that end, a condition is included in the Consolidated Authorization requiring a minimum 12-inch clearance between the deepest draft of a vessel with the motor in the "down" position and the top of submerged resources at mean low water. The parties stipulated, and Shafnacker testified, that with the exception of the 32-foot-long Marlin Barge and the 10- foot-long Galligan barges, all other barges in Workboats' fleet will moor at the three-pile dolphins near the southern boundary of the Lease. Some barges will be anchored to the substrate by spuds, and the condition requiring 12 inches of clearance between the vessel bottom and the top of submerged resources would not apply to the spuds themselves. The parties stipulated, and Shafnacker testified, that Workboats will only load vessels from Dock B, which is appurtenant to Lot 8, and that the only equipment that will be used to load vessels will be equipment small and light enough to traverse Dock B——specifically, a Takeuchi mini-excavator, small forklift, or similarly-sized equipment. These limitations regarding the loading of vessels within the Lease area are not currently included as conditions of the Consolidated Authorization. Based on the parties' stipulation and competent substantial evidence in the record, conditions should be added to the Consolidated Authorization expressly limiting the loading of vessels in the Lease area to occurring only on Dock B, and limiting the type of equipment used for vessel loading and unloading to forklifts, mini-excavators, or similar light equipment. Shafnacker testified that the only other work that may be performed within the Lease area would consist of certain minor maintenance activities on Workboats' vessels; these minor repair activities include non-routine paint touchups and handrail painting, minor cable and winch repairs, and minor steel-rod (non-lead) welding. DEP Review and Approval of the Project Workboats filed a Joint Application for Individual Environmental Resource Permit/Authorization to Use State-Owned Submerged Lands/Federal Dredge and Fill Permit ("Application") on or about June 15, 2018. The Application was determined to be complete. DEP staff reviewed the Application and determined that the Project, as proposed, met the applicable statutory standards and rule requirements for issuance of the Consolidated Authorization. DEP issued the Consolidated Notice of Intent on or about July 20, 2018, proposing to issue the environmental resource permit and Lease for the Project. The Application, Consolidated Notice of Intent, and Consolidated Authorization were admitted into evidence at the final hearing. Compliance with Rule 62-330.301 For Workboats to be entitled to issuance of the environmental resource permit for the Project, it must provide reasonable assurance9/ that the Project meets the requirements of rule 62-330.301.10/ Water Quantity, Storage, Conveyance, and Flooding Impacts The entire Project, as proposed, will be constructed waterward of the mean high water line and will consist of mooring piles, piling-supported docks, and floating docks. These structures will not affect, impound, store, divert, or impede the amount or flow of surface water. The evidence demonstrated that the Project, if constructed and operated as proposed, will not cause adverse water quantity impacts to receiving waters and adjacent lands; will not cause adverse flooding to on-site or off-site property; and will not cause adverse impacts to existing surface water storage and conveyance capabilities. Impacts to Value of Functions Provided to Fish, Wildlife, Listed Species, and Habitat Two types of habitat exist at the Project site: salt marsh and submerged benthic habitat. The evidence established that the salt marsh at the Project site is healthy, high-quality, high-functioning salt marsh habitat. Among the functions the salt marsh provides are preservation and improvement of water quality by filtering runoff, serving as a nursery for fish species, preventing shoreline erosion, and forming the base of the estuarine food chain. The salt marsh, in combination with existing riprap at the edge of the salt marsh, forms a "living shoreline" at the Project site that helps protect the shoreline from erosion and scouring due to wave action. This living shoreline is not being removed or otherwise affected, and will remain in place at the Project site. The submerged benthic sediment at the Project site consists of high organic silts and a sand base. The evidence established that the benthic sediment provides habitat for infauna, such as polychaete worms; and for epifauna, such as shrimp, crabs, and mollusks. No submerged aquatic vegetation or oyster bars were found at the Project site. Docks A and B consist of extensions that will be added to two existing docks that previously were constructed through the salt marsh. These extensions will be constructed four feet above the marsh floor to reduce shading, using minimally- impactful construction techniques, discussed above, to help avoid and minimize construction impacts to the marsh. The floating components of docks A and B will not have any impact on the salt marsh habitat. Dock C will be constructed waterward of Lot 9, across a very small section of salt marsh grass. It also will be elevated four feet above the marsh floor to reduce shading, and will be constructed using the same minimally-impactful technique, to avoid and minimize impacts to the marsh. Because Dock C will have only de minimis impacts on the salt marsh, no mitigation has been required. The Consolidated Authorization contains conditions requiring Workboats to avoid impacts to emergent grasses during construction and operation of the Project, and prohibiting Workboats from storing or stockpiling tools, equipment, materials, and debris within wetlands. These conditions will help ensure that the Project will have only minimal impacts on the salt marsh habitat at the Project site. The Consolidated Authorization contains a specific condition requiring maintenance of a minimum 12-inch clearance between the deepest draft of the vessel, with the motor in the down position, and the top of submerged resources for all vessels that will use the docking facility. Additionally, the construction of mooring areas over submerged grass beds is prohibited. These conditions will help protect benthic habitat at the Project site. The Florida Manatee is the only listed species that inhabits the Project site. Video evidence presented by the City showed manatees present at, and in the vicinity of, the Project site. The Project is located in an area designated, in the most recent Duval County Manatee Protection Plan (November 2017) ("MPP"), as "preferred" for boat facility siting. Boating facilities located in designated "preferred" areas generally do not have any limits on the number of slips at the facility. "Preferred" boat facility siting areas were designated in the MPP based on many factors, including manatee abundance, presence of manatee feeding habitat, proximity to boating destinations, manatee mortality in the area, existing boating slip numbers and locations, boating facility type and number, and existence of speed zones. To protect manatees in the Back Channel, the Florida Fish and Wildlife Conservation Commission ("FWC") has, by rule, established a slow speed, minimum wake zone extending 300 feet from the shorelines into the Back Channel. A slow speed, minimum wake zone means that a vessel must be fully off-plane and completely settled into the water, proceeding at a speed which is reasonable and prudent under the prevailing circumstances so as to avoid the creation of an excessive wake or other hazardous condition which endangers or is likely to endanger other persons using the waterway.11/ Fla. Admin. Code R. 68C-22.02(4). The existence and enforcement of this speed zone will help protect manatees in the Back Channel. Conditions also have been included in the Consolidated Authorization to help protect manatees from impacts from the Project. As previously discussed, for each vessel, a minimum 12-inch clearance between the deepest draft with the motor down, and the top of the submerged resources at mean low water, must be maintained. This condition will help ensure that manatees do not become trapped under or crushed by a vessel while moored in the Lease area. Additionally, bumpers or fenders must be installed and maintained to provide at least three feet of separation between moored vessels and between the docks/mooring piles and vessels, to help prevent trapping or crushing of manatees. The Consolidated Authorization also requires the Project to be constructed and operated in accordance with the Standard Manatee Conditions for In-Water Work. These conditions include: instructing all personnel, including construction personnel, about the presence of manatees and manatee speed zones, and the need to avoid collisions with and injury to manatees, as well as about civil and criminal penalties imposed for harming, harassing, or killing manatees; operating all vessels associated with construction of the Project at "idle speed/no wake" at all times in the vicinity of the Project and where the draft of the vessel provides less than a four-foot clearance from the bottom; the requirement that all in-water operations, including vessels, must shut down if a manatee comes within 50 feet of the operation and cannot resume until the manatee either moves beyond the 50-foot radius of the operation or 30 minutes has elapsed and the manatee has not reappeared within 50 feet of the operation; the installation of specified temporary signage; and the installation of specified permanent signage. The inclusion of these conditions in the Consolidated Authorization provides reasonable assurance that the construction and operation of the Project will not adversely affect the value of functions provided to fish, wildlife, or listed species and their habitats. Water Quality Impacts As previously noted, the St. Johns River, including the Back Channel, is a Class III waterbody. Accordingly, the surface water quality standards and criteria applicable to Class III waters in Florida codified in Florida Administrative Code Rule 62-302.300 apply to the Back Channel. The Back Channel portion of the St. Johns River has been identified as impaired for lead, pursuant to Florida Administrative Code Chapter 62-303. The credible, persuasive evidence demonstrates that the Project, if constructed and operated in accordance with the conditions currently included in the Consolidated Authorization along with additional conditions discussed below, will not cause or contribute to water quality violations. Specifically, the Project will be required to install and maintain turbidity barriers during the construction phase to help ensure that any sediment disturbed during construction does not cause or contribute to water quality violations. Additionally, as discussed above, a minimum 12-inch clearance between the deepest draft of each vessel, with the motor down, and the top of the submerged resources at mean low water must be maintained. This will help prevent the suspension of sediments, and any constituents in those sediments, from being suspended in the water column and causing or contributing to water quality violations, as a result of the Project. The Consolidated Authorization also prohibits the storage or stockpiling of tools, equipment, materials, such as lumber, pilings, riprap, and debris within wetlands or other waters of the state; prohibits the discharge of construction debris into waters of the state; prohibits the overboard discharge of trash, human or animal waste and fuel at the docks; and requires all work to be done in periods of average or low water, so that impacts to submerged resources, including bottom sediment, can be avoided. Collectively, these conditions help provide reasonable assurance that the construction and operation of the Project, including the mooring and operation of vessels in the Lease area, will not violate water quality standards. White testified that, generally, the water quality in, and in the vicinity, of marinas degrades over time due to the discharge of oils, greases, and other waste; and the suspension in the water column of sediments and toxins, pesticides, herbicides, and heavy metals in those sediments, as a result of propeller dredging. However, Irwin testified that because the Project site is located in a tidally-influenced area, with an approximate 3.5-foot tide range over multiple tide changes per day, the Project site will be adequately flushed such that there will not be an accumulation of pollutants that may violate water quality standards. Based on Irwin's persuasive testimony, it is determined that water quality violations will not occur due to an accumulation of pollutants at the Project site. To further ensure that the Project will not degrade water quality or violate water quality standards at the Project site, the Consolidated Authorization requires Workboats to submit a facility management plan to address maintenance and unexpected spills of fuels and other pollutants. The facility management plan must include a spill response plan for fuel spills; a plan for maintenance of gray water collection systems and return systems, to the extent applicable; a plan addressing garbage collection and vessel cleaning systems to prevent disposal of waste in wetlands; and an education plan for all employees at the Project regarding fueling, sewage and gray water pump operations, waste management, and facility maintenance. Sewage pump-out facilities are not proposed as part of the Project. Shafnacker testified, and the Consolidated Authorization, Project Description section currently states, that domestic waste from boat heads will be handled through use of a waterless incinerating toilet (Incinolet or similar), and the remaining ash shall not be disposed of in waters of the state. However, it is noted that this requirement is not currently included as an enforceable condition. The undersigned finds that a specific condition expressly prohibiting any sewage pump-out at the docks or on vessels, requiring the use of an incinerator toilet, and prohibiting the discharged of ash waste should be included in the Consolidated Authorization to provide reasonable assurance that the Project will not violate water quality standards due to the discharge of sewage into waters of the state. The Consolidated Authorization, Project Description section, states: This permit does not authorize the installation and use of fueling equipment at the Dock; the discharge of waste into the water; liveaboards; fish cleaning or the installation of fish cleaning stations; repair and maintenance activities involving scraping, sanding, stripping, recoating, and other activities that may degrade water quality or release pollutants into Waters of the State. Major repair, reconstruction, and/or other service must be performed at a facility approved for vessel haul-out and repair. This does not preclude the light maintenance allowed under Specific Condition 18 to be performed at the facility. This language, which expressly identifies numerous activities that are prohibited in connection with the operation of the Project, is not currently included as an enforceable condition in the Consolidated Authorization. The undersigned determines that in order to protect water quality at the Project site, this language must be included as a specific condition in the Consolidated Authorization. As previously noted above, the Back Channel is impaired for lead. Both Irwin and Hallett testified that Workboats would not use lead paint or lead-containing welding equipment on the docks or vessels moored in the Lease area. To provide reasonable assurance that the Project will not constitute a source of lead that will contribute to the impaired status of the Back Channel, a specific condition prohibiting the use of lead-based paints and other sources of lead should be included as an enforceable condition in the Consolidated Authorization. Based on the foregoing, the undersigned finds that, with the addition of the conditions discussed in paragraphs 68, 69, and 70 above, Workboats has provided reasonable assurance that applicable water quality standards will not be violated as a result of construction or operation of the Project. Adverse Secondary Impacts to Water Resources Secondary impacts are impacts caused by other relevant activities very closely linked or causally related to the activity itself, rather than the direct impacts of the proposed activity itself.12/ The conditions currently included in the Consolidated Authorization, along with the conditions addressed in paragraphs 68, 69, and 70 above, provide reasonable assurance that the Project will not cause adverse secondary impacts to water quality. Additionally, the Project will not cause adverse secondary impacts to the functions of wetlands and surface waters, aquatic or wetland-dependent species, or listed species. As discussed above, the salt marsh habitat will not be disturbed during construction and operation of the Project, and the benthic habitat will be protected by the minimum 12-inch vessel to the top of submerged resource clearance requirement discussed above. These Project features and conditions will help ensure that there are no adverse impacts to wetland functions and to aquatic or wetland-dependent species, such as fish and benthic fauna. Additionally, the Project will be located within a slow speed, minimum wake zone, and Workboats will be required to operate all of its vessels in compliance with that standard within the 300-foot buffer along the shorelines of the Back Channel. This operational constraint, along with additional manatee protection conditions discussed above, provide reasonable assurance that the Project will not cause adverse secondary impacts to manatees. Based on the foregoing, it is determined that, with the addition of the conditions addressed in paragraphs 68, 69, and 70, above, Workboats has provided reasonable assurance that the Project will not have adverse secondary impacts to the water resources. Impacts to Ground and Surface Water Levels and Surface Water Flows As discussed above, the Project will be constructed waterward of the mean high water line, and will consist of piling-supported and floating docks and mooring piles that will not adversely impact the maintenance of minimum surface or ground water levels or surface water flows at the Project site. Impacts to Works of the District The Project is not proximate to any works of the district, as approved pursuant to section 373.086; accordingly, it will not cause adverse impacts to such works. Capable of Performing and Functioning as Designed The Project was designed by an engineer and will be installed by Shafnacker, who is an experienced marine contractor. The Consolidated Authorization requires that the Project must be implemented in accordance with the approved plans, specifications, and performance criteria. Within 30 days of completion of construction of the Project, Workboats must submit an as-built survey, signed and sealed by a Florida licensed Surveyor and Mapper in accordance with Florida Administrative Code Chapter 61G17-7, depicting the boundaries of the Lease, and showing the size and dimensions of all existing overwater structures and activities within the Lease area. Additionally, the surveyor must provide a statement that all of the depicted structures and activities are located within the Lease area; or identify, and depict on an as-built survey, any structures or activities outside of the Lease area. These requirements will ensure that the Project performs and functions as designed. Financial, Legal, and Administrative Capability Rule 62-330.301(1)(j) requires an applicant for an environmental resource permit to provide reasonable assurance that the project will be conducted with a person having the financial, legal, and administrative capability to ensure that the activity will be undertaken in accordance with the terms and conditions of the permit.13/ The Environmental Resource Permit Applicant's Handbook, Volume I (General and Environmental) ("Handbook"), section 1.5.1., which provides further guidance regarding compliance with the requirement in rule 62-330.301(1)(j), states that "[c]ompliance with this requirement must be demonstrated through subsections 62-330.060(3) and (4), the certification required in the Application Form 62-330.060(1), and section 12.0 of the Handbook." As part of the Application, Workboats submitted copies of warranty deeds for lots 6, 7, and 8, and Disclaimer No. 22146 for Lot 9. These documents establish that Shafnacker holds title to the uplands on lots 6 through 9 and to certain submerged lands waterward of Lot 9. Pursuant to Handbook section 4.2.3, these documents satisfy the "sufficient upland interest" requirement in rules 62.330.060(3) and 62- 330.301(1)(j). Rule 62-330.060(3) also requires the applicant and/or the applicant's agent to sign specific parts of the application. Here, Workboats, and Shafnacker, as Workboats' agent, signed the pertinent portions of the Application, as required by this rule. Rule 62-330.060(4) and pertinent provisions of section 12.0 of the Handbook——specifically, provisions in sections 12.1 and 12.2——require that once construction of the permitted activity is complete, it must be converted to the operational phase by submitting an as-built certification and request for conversion to operational phase. Here, the Consolidated Authorization for the Project requires submittal of this form, once construction is complete, as a condition for operation of the Project. These are the only rules and Handbook provisions regarding demonstration of financial, legal, and administrative capability that are pertinent to the Project. No other environmental resource permitting rules or Handbook provisions impose any other requirements regarding financial capability, and the City has not identified any case law or other statutes or rules imposing additional pertinent financial capability requirements. Thus, the evidence establishes that Workboats meets rule 62-330.301(1)(j) and all other pertinent rules and Handbook requirements, showing it has the financial, legal, and administrative capability to ensure the Project will be undertaken in accordance with the terms and conditions of the Consolidated Authorization. The City did not present any evidence to show that Workboats lacks the financial, legal, and administrative capability to undertake the Project as permitted. Compliance with Rule 62-330.302 For Workboats to be entitled to issuance of the environmental resource permit for the Project, it also must provide reasonable assurance that the Project meets the requirements of rule 62-330.302,14/ which establishes additional standards for issuance of environmental resource permits for activities in surface waters or wetlands. Adverse Effects to Public Health, Safety, or Welfare, or Property of Others In determining whether a proposed activity in surface waters or wetlands would adversely affect the public health, safety, or welfare, or the property of others, the focus is on environmental hazards or injuries that may result from the proposed activity.15/ Thus, alleged threats to personal safety and enjoyment of neighboring property resulting from alleged unlawful activities on the upland areas of lots 6, 7, and 916/—— which are not part of the Project——are not appropriately considered as part of the public interest determination under rule 62-330.302. As discussed above, the Consolidated Authorization contains conditions aimed at ensuring that water quality is not degraded and water quality standards are not violated due to the Project. These conditions, along with conditions addressed in paragraphs 68, 69, and 70, above, provide reasonable assurance that the public health, safety and welfare, and property of others will not be adversely affected as a result of water quality degradation or violations. The Project, as designed and approved, will have 25-foot setbacks from the eastern and western riparian rights lines for lots 6 through 9. These setbacks will help ensure that the construction and operation of the Project will not interfere with the adjoining properties' riparian rights. The City presented the testimony of O'Connor, who opined that some of Workboats' vessels, operated at full throttle, were capable of generating a wake as high as three feet. O'Connor testified that a wake of this height could damage docks along the shoreline of the Back Channel, cause shoreline erosion, and create a safety hazard for recreational boaters, kayakers, and others engaged in in-water recreational activities. As discussed above, the Back Channel is approximately 1,300 feet wide at the Project site. Per the location map provided as part of the specific purpose survey, the portion of the Back Channel east of the Project site is at least this wide for its entire length. Shafnacker testified, credibly, that his vessels typically operate closer to the Blount Island shoreline than the northern shoreline of the Back Channel, so are approximately 800 feet away from the northern shoreline where the residential docks and access points for boaters, kayakers, and other recreational uses are located. Additionally, Shafnacker credibly testified that Workboats' boats and barges would be operated at speeds such that the highest wake that any of his vessels would generate is two feet. Based on the foregoing, and with the inclusion in the Consolidated Authorization of the conditions addressed in paragraphs 68, 69, and 70, above, Workboats has provided reasonable assurance that the Project will not adversely affect the public health, safety, welfare, and property of others. Adverse Effects to Conservation of Fish, Wildlife, Listed Species, and their Habitats As previously discussed, the Consolidated Authorization requires Workboats to avoid impacts to emergent grasses during construction and operation of the Project, and prohibits Workboats from storing or stockpiling tools, equipment, materials, and debris within wetlands. These conditions will help ensure that the Project will have minimal impact on the salt marsh habitat at the Project site. The Consolidated Authorization also contains a condition prohibiting the construction of mooring areas over submerged grass beds. This, along with the condition requiring a minimum 12-inch clearance between vessel bottom and submerged resources, will help protect the benthic habitat at the Project site. Additionally, the Consolidated Authorization imposes conditions to protect manatees from impacts due to the Project. Specifically, bumpers or fenders must be installed and maintained to provide at least three feet of separation between docks or mooring piles and vessels, and between vessels, and a minimum 12-inch clearance between the deepest draft of the vessel and the top of the submerged resources at mean low water must be maintained. The Project also must be constructed and operated in accordance with the FWC's Standard Manatee Conditions for In-Water Work, which imposes construction and operational requirements to protect manatees for the life of the Project. The inclusion of these conditions in the Consolidated Authorization provides reasonable assurance that the Project will not adversely affect the conservation of fish and wildlife, including threatened species and their habitats. Adverse Effects to Navigation, Flow of Water, or Shoaling The Back Channel is navigable, and is over 1,300 feet wide at the point at which the Project is proposed to be located. It is used by a mix of recreational vessels and commercial and industrial vessels, although, as noted above, the low-clearance bridges on the western end of Blount Island effectively limit the commercial and industrial traffic to smaller-sized vessels. As depicted on the specific purpose survey submitted as part of the Application, the southern boundary of the Lease extends waterward approximately 196 feet from the shoreline at the eastern boundary of the Lease, and approximately 174 feet from the shoreline at the western boundary of the Lease. Thus, at its most waterward point, the preempted area of the Lease will extend waterward approximately 14 percent of the width of the Back Channel.17/ The specific purpose survey shows docks A and C extending waterward approximately 60 feet from the shoreline, and shows Dock B extending waterward approximately 45 feet from the shoreline.18/ The three three-pile dolphins, which will be used to moor the largest barges, will be set back approximately 38 feet from the southern boundary of the Lease. Shafnacker testified that barges moored at the three-pile mooring dolphins will be tied between the dolphins, by ropes at their bows and sterns, to ensure that they do not drift out of the Lease area and create a navigational hazard. The Consolidated Authorization contains a condition requiring the waterward ends of the docks and the mooring dolphins to be marked by reflectors so as to be visible from the water at night by reflected light. However, at the hearing, Shafnacker testified that he intended to mark the dolphins and barges with solar battery-powered lights so that they would be more visible at night than if only reflectors are used. Based on this testimony, it is recommended that Specific Condition No. 13 in the Consolidated Authorization be modified to require the barges and mooring dolphins to be marked by lights, as well as reflectors, to make them more visible from the water. Based on the foregoing, it is determined that the Project, as proposed, will not adversely impact navigation in the Back Channel. Specifically, the Lease will not extend a significant distance out into the Back Channel; approximately 86 percent of the width of the Back Channel at the Project site remains open for navigation by the public. Additionally, the docks will be located relatively close to the shoreline, well within the Lease preempted area, and will be marked so that they are visible from the water. The mooring dolphins also will be set back a substantial distance from the Lease boundary and will be marked so as to be visible from the water. The evidence shows that the Project will not have any adverse effects on the flow of water. As discussed above, the Project will not impede, impound, or otherwise affect the flow of water. The evidence also shows that the Project will not cause harmful shoaling or erosion. No dredging or placement of dredged spoil is proposed or authorized as part of the project, and the Consolidated Authorization requires Workboats to use silt fencing and other specified best management practices to stabilize the sediment and prevent erosion and shoaling during construction of the Project. For these reasons, it is determined that the Project will not adversely impact navigation in the Back Channel, will not adversely affect the flow of water, and will not result in harmful shoaling or erosion. Adverse Effects to Fishing, Recreational Values, or Marine Productivity The Back Channel is a meander of the St. Johns River that no longer is used as the main navigational channel for the river. Thus, it is relatively calm and is extensively used for boating, kayaking, swimming, fishing, jet skiing, and other in- water recreational activities. The evidence establishes that the Project will not adversely affect fishing, recreational values, or marine productivity in the vicinity. The salt marsh habitat in the vicinity of the Project, which serves as the base of the estuarine food chain and as a nursery and refuge for small fish, will not be disturbed during construction of the Project. As such, the Project will not adversely affect fish habitat or marine productivity. Additionally, because the Project will be constructed within the boundaries of the Lease and set back 25 feet from the riparian lines for the adjoining properties, it will not physically interfere with or displace fishing activities from those properties, or from any other property in the vicinity. The Consolidated Authorization imposes conditions to protect water quality during construction and operation of the Project. These conditions, and the additional conditions, discussed in paragraphs 68, 69, and 70, above, will protect water quality, and therefore help protect fish habitat and marine productivity. The credible evidence establishes that vessel operation associated with the Project will not adversely affect boating, kayaking, fishing, or other recreational activities in the vicinity. As discussed above, the Project is located in a slow speed, minimum wake zone that extends 300 feet from the shoreline into the Back Channel, and all vessels traversing into and out of the Lease area must operate at this speed until they are beyond 300 feet from the shorelines. Additionally, Shafnacker credibly testified that once out of the 300-foot slow speed, minimum wake zone, the vessels will operate at speeds such that they will generate a wake of two feet, at most. The evidence showed that wakes of this height are not anticipated to adversely affect recreational activities in the Back Channel. Temporary or Permanent Activity The Project will be permanent. However, the evidence establishes that there are numerous permanent docking facilities along the northern shoreline of the Back Channel, so the Project is not unique in that regard. Adverse Impacts to Significant Historical or Archaeological Resources The Department of State, Division of Historical Resources ("DHR"), did not provide any comments indicating that significant historical or archaeological resources are anticipated to be present at the Project site, and no evidence was presented showing that the Project would have any adverse impacts to such resources. As a precaution, the Consolidated Authorization contains a specific condition requiring Workboats to immediately cease all activities involving subsurface disturbance and to contact DHR if any prehistoric or historic artifacts, such as pottery or ceramics, project points, dugout canoes, metal implements, historic building materials, or any other physical remains that could be associated with Native American, early European, or American settlements are encountered at any time within the Project site. Accordingly, it is determined that the Project will not adversely affect significant historical or archaeological resources. Current Condition and Relative Value of Functions The salt marsh wetlands in the vicinity of the Project are healthy, high-functioning, and part of a "living shoreline" that will not be disturbed by construction or operation of the Project. Although Dock C will be constructed across a very small patch of salt marsh, it will be elevated to reduce shading and will be constructed using minimally-impactful construction techniques. Any impacts to the salt marsh from the Project will be de minimis. The Project is also not anticipated to adversely affect the condition and relative value of the benthic habitat on the Project site. As discussed above, the Consolidated Authorization imposes a minimum 12-inch clearance from vessel bottom to top of submerged resources requirement, which will help prevent physical impact to, and propeller dredging of, the benthic habitat at the Project site. Conditions in the Consolidated Authorization, as well as the conditions addressed in paragraphs 68, 69, and 70, above, also will help protect the current condition and relative value of the salt marsh and benthic habitat on the Project site. Unacceptable Cumulative Impacts to Wetlands and Surface Waters With the conditions currently contained in the Consolidated Authorization, along with the conditions addressed in paragraphs 68, 69, and 70, above, the Project is not anticipated to have adverse water quality impacts. Additionally, as discussed above, the Project is not anticipated to cause adverse impacts to fish, wildlife, protected species, and their habitat. Therefore, with the inclusion of the conditions discussed in paragraphs 68, 69, and 70, above, reasonable assurance has been provided that the Project will not have unacceptable cumulative impacts, in violation of rule 62- 330.302(1)(b). Past Violations of Water and Wetlands Statutes and Rules The City presented evidence consisting of videos and photographs taken from the Wood residence immediately east of Lot 9. These videos and photographs show a variety of activities that are potentially damaging to surface waters and wetlands, including dumping sediment into surface waters from a moored vessel; earthmoving; moving floating docks onto, and off of, the shoreline using heavy equipment; operating heavy equipment in wetlands and surface waters along the shoreline; and mooring boats in extremely shallow water. Wood testified, credibly, that he contacted DEP numerous times, and that DEP occasionally visited Shafnacker's property——typically days after Wood had contacted the agency. Upon inspecting the Workboats site, DEP determined that barges or other equipment or materials had been dragged onto the shoreline without proper authorization, and DEP issued a compliance assistance offer letter to address this noncompliance. DEP ultimately determined that, rather than taking enforcement action for this noncompliance, a salt marsh restoration corrective action requirement should be included in the Consolidated Authorization. The corrective action conditions require Workboats to submit a salt marsh restoration plan and impose restoration plan completion timeframes, success criteria, and monitoring requirements. Given Workboats' noncompliance history, the undersigned determines that in order to provide reasonable assurance that the Project will not violate environmental resource permitting statutes and rules, the conditions addressed above in paragraphs 35, 68, 69, and 70, above, must be included as enforceable conditions in the Consolidated Authorization. Compliance with Chapter 18-21 for Issuance of the Lease For Workboats to be entitled to issuance of the Lease, it must demonstrate, by a preponderance of the evidence, that it will meet the applicable requirements and standards codified in Florida Administrative Code Chapter 18-21 for issuance of a sovereignty submerged lands lease. Water Dependent Activities Rule 18-21.004(1)(g) requires activities on sovereignty submerged lands to be limited to those that are water dependent. A "water dependent activity" is one that can only be conducted in, on, over, or adjacent to water areas because the activity requires direct access to the water body or sovereignty submerged lands for specified activities, including recreation, and where the use of water or sovereignty submerged lands is an integral part of the activity. Fla. Admin. Code R. 18- 21.003(71). The Project's proposed docks, mooring piles, mooring dolphins, and vessel mooring operations are water dependent activities. The Project's primary purpose is the water dependent activity of mooring vessels and the ancillary activity of loading vessels with supplies as part of Workboats' operation. Case law interpreting Florida Administrative Code Chapter 18-21 holds that because the primary purpose of docks and other mooring structures is to moor vessels, they are "water dependent" activities for purposes of rule 18-21.004(1)(g).19/ As discussed in paragraphs 35, 68, 69, and 70, above, a condition should be included in the environmental resource permit and Lease specifically prohibiting any major repair, reconstruction, or maintenance activities within the Lease area, in order to ensure that only water dependent activities are conducted within the Lease area. Resource Management Requirements Rule 18-21.004(2)(a) requires sovereignty submerged lands to be managed primarily for the maintenance of natural conditions, propagation of fish and wildlife, and traditional recreational uses such as fishing, boating, and swimming. Additionally, the rule authorizes compatible secondary uses that will not detract from or interfere with these primary purposes. As discussed above, the evidence establishes that the Project, as proposed and conditioned in the Consolidated Authorization, will not adversely affect salt marsh or benthic habitat, will not degrade water quality or cause or contribute to water quality violations, and will not adversely affect fish, wildlife, listed species, and marine productivity. Accordingly, the Project will not detract from, or interfere, with fish and wildlife propagation. The evidence also establishes that the Project will not detract from, or interfere with, traditional recreational uses. As discussed above, the Back Channel is wide enough to accommodate vessels traveling to and from the Project site without detracting from or interfering with recreational activities conducted in the Back Channel. Additionally, vessels traveling to and from the Project site must be operated in accordance with the slow speed, minimum wake zone within the 300-foot shoreline buffer, and will be operated at speeds that will generate a maximum two-foot wake outside of the shoreline buffer. The evidence shows that these speeds will not detract from, or interfere with, traditional recreational uses in the Back Channel. The Project also has been designed, and will be operated, to minimize or eliminate wetland vegetation impacts and impacts to fish and wildlife habitat and cultural resources. Specifically, as discussed above, impacts to the salt marsh habitat have been minimized through the use of minimally- impactful construction techniques and elevating docks four feet above the marsh to reduce shading of the marsh grasses. Additionally, the 12-inch minimum vessel/submerged resource clearance condition will reduce impacts to the benthic habitat in the Lease area. As discussed above, DHR did not provide comments indicating that significant historical or archaeological resources are anticipated to be present at the Project site, and no evidence was presented showing that the Project would have any impacts to such resources. Additionally, the Consolidated Authorization contains a specific condition establishing protocol for Workboats to follow if any specified artifacts are encountered at any time within the Project site. Rule 18-21.004(7)(e) requires that construction, use, or operation of the structure or activity not adversely affect any species listed as endangered, threatened, or of special concern in FWC rules. As discussed above, the Florida Manatee is the only listed species determined to be present the Project site. The Project site is located within an established slow speed, minimum wake zone, and vessels entering and leaving the Project site must comply with this speed limitation within the 300-foot shoreline buffer area. Additionally, the Consolidated Authorization includes several conditions designed to reduce and minimize potential impacts to manatees that may enter the Lease area. Collectively, these requirements and conditions will help ensure that the construction and operation of the Project will not adversely affect manatees. Riparian Rights As part of the Application, Workboats submitted deeds and Disclaimer No. 22146, demonstrating that Shafnacker holds title to lots 6, 7, 8, and 9. These documents constitute "satisfactory evidence of sufficient upland interest," as that term is defined in rule 18.21.003(60). Consistent with rule 18-21.004(3)(d), the Project is proposed to be constructed in the riparian area appurtenant to lots 6, 7, 8, and 9, and all structures that are part of the Project will be set back at least 25 feet from the eastern and western riparian lines for the upland property. No evidence was presented showing that the construction or operation of the Project would unreasonably restrict or infringe upon the riparian rights of adjacent upland owners, in violation of rule 18-21.004(3)(c). It is determined that the Project will not unreasonably infringe on or restrict the riparian rights of adjacent upland riparian owners, so meets the requirements and standards in rule 18-21.004(3) regarding riparian rights. Navigational Hazard For the reasons discussed in paragraphs 102 through 107, above, it is determined that the Project will not constitute a navigational hazard, in violation of rule 18- 21.004(7)(g). However, the inclusion of a condition requiring lighting of the mooring dolphins, discussed in paragraph 106, is recommended to ensure the Project will not constitute a navigational hazard. Lease Fees As part of the Application, Workboats submitted a financial affidavit attesting to its ability to pay the required fees for the Lease, imposed pursuant to rules 18-21.008 and 18-21.011. Not Contrary to the Public Interest Rule 18-21.004 establishes the sovereignty submerged lands management policies, standards, and criteria to be used in determining whether to approve activities on sovereignty submerged lands. The term "public interest" is defined to mean "demonstrable environmental, social, and economic benefits which would accrue to the public at large as a result of the proposed action, and which would clearly exceed all demonstrable environmental, social, and economic costs of the proposed action." Fla. Admin. Code R. 18-21.003(51). To meet the "not contrary to the public interest" standard in rule 18-21.004(1)(a), it is not necessary that the applicant show that the activity is affirmatively in the "public interest," as that term is defined in rule 18-21.003(51). Rather, it is sufficient that the applicant show that there are few, if any, "demonstrable environmental, social, and economic costs" of the proposed activity. Castoro v. Palmer, Case Nos. 96-0736, 96-5879 (Fla. DOAH Sept. 1, 1998; Fla. DEP Oct. 19, 1998). Here, the City asserts that the Lease is contrary to the public interest because it will cause adverse impacts to benthic and salt marsh habitat; discharge pollutants into the waters of the Back Channel; harm manatees; pose a navigational hazard; and detract from, and interfere with, recreational activities in the Back Channel. However, as discussed above, the evidence shows that the Project has been designed specifically to minimize many of these impacts, and the Consolidated Authorization contains conditions specifically aimed at preventing many of these alleged impacts. As discussed above, other conditions, discussed in paragraphs 68, 69, 70, 106, and 138, also should be included in the Consolidated Authorization to ensure that the Project will not cause adverse impacts to habitat resources, water quality, manatees, and navigation. Case law interpreting the public interest test in rule in 18-21.004(1)(a) applicable to proprietary approvals holds that when proposed structures or activities meet the applicable standards and criteria in chapter 18-21, those structures or activities are presumed to be not contrary to the public interest. See Spinrad v. Guerro and Dep't of Envtl. Prot., Case No. 13-2254 (Fla. DOAH July 25, 2014), modified in part, Case No. 13-0858 (Fla. DEP Sept. 8, 2014); Haskett v. Rosati and Dep't of Envtl. Prot., Case No. 13-0465 (Fla. DOAH July 31, 2013), modified in part, Case No. 13-0040 (Fla. DEP Oct. 29, 2013). Here, Workboats has demonstrated that the Project meets all applicable standards and criteria in chapter 18-21; thus, the Project is presumed to be not contrary to the public interest under rule 18-21.004(1)(a).20/ The City did not present persuasive evidence showing that, on balance, the demonstrable environmental, social, and economic costs of the Project exceed the demonstrable environmental, social, and economic benefits accruing to the public.21/ Accordingly, it is determined that the Project meets the public interest test in rule 18- 21.004(1)(a). Entitlement to Environmental Resource Permit Workboats met its burden under section 120.569(2)(p) to present a prima facie case of entitlement to the environmental resource permit by entering into evidence the Application, Notice of Intent, Consolidated Authorization, and supporting information. Workboats also presented credible, competent, and substantial evidence beyond that required to meet its burden to demonstrate prima facie entitlement to the environmental resource permit. The burden then shifted to the City to demonstrate, by a preponderance of the competent substantial evidence, that the Project does not comply with sections 373.413 and 373.414 and applicable environmental resource permitting rules. For the reasons discussed above, it is determined that the City did not meet its burden of persuasion under section 120.569(2)(p). Accordingly, for the reasons discussed above, it is determined that, with the inclusion of conditions in the Consolidated Authorization addressed in paragraphs 35, 68, 69, 70, and 106, above, Workboats meets all applicable requirements for issuance of the environmental resource permit for the Project. Entitlement to Lease As discussed above, Workboats bore the burden of proof in this proceeding to demonstrate, by a preponderance of the evidence, that the Project meets all applicable statutory and rule requirements for issuance of the Lease. For the reasons discussed above, it is determined that Workboats met this burden, and, therefore, is entitled to issuance of the Lease for the Project. The City's Standing As previously noted, the City is a consolidated municipality and county political subdivision of the State of Florida. The Project is located within the geographic boundary of the City. On or about July 26, 2018, the Council of the City of Jacksonville, Florida, adopted Resolution 2018-499-A, finding that issuance of the environmental resource permit and Lease affects the substantial interests of a significant number of residents in Duval County. The City initiated this proceeding by filing its Petition with DEP on August 17, 2018, alleging that the Project will have the effect of impairing, polluting, or otherwise injuring the air, water, or other natural resources of the state.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order approving the issuance of Consolidated Environmental Resource Permit and Recommended Intent to Grant Sovereignty Submerged Lands Authorization, Permit No. 16-0345934-003-EI, on the terms and conditions set forth in the Consolidated Notice of Intent and attached draft amended Permit No. 16-0345934-003-EI, as modified to include the conditions addressed in paragraphs 35, 68, 69, 70, 106, and 137, above. DONE AND ENTERED this 1st day of March, 2019, in Tallahassee, Leon County, Florida. S CATHY M. SELLERS 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 1st day of March, 2019.
Findings Of Fact Background Respondent Telese is the owner and developer of Egret Woods Subdivision on real property contiguous to state waters in Pinellas County, Florida. The property is near the incorporated areas of Indian Shores and Largo. A residential subdivision borders the project locale to the east, and tidal mangrove swamps fringe the property to the west. An intracoastal connecting waterway known as the "Narrows" lies to the west of the swamps. These state waters connect Boca Ceiga Bay and Clearwater Harbor. The proposed subdivision area is an upland strip between the existing subdivision and the tidal swamp adjacent to the "Narrows". The uplands are predominantly vegetated by live oak, saw palmettos and slash pines. In order to develop the property, and to reconfigure lots from a previously platted subdivision, Respondent Telese applied for a permit from DER to fill 0.12 acres of DER jurisdictional wetlands located at the development site. The application for the permit represents that 340 cubic yards of clean, non-deleterious sandy loam is needed to fill disturbed high marsh areas and other low areas on the proposed lots. Respondent Telese has also requested permission to install culverts in the two conveyance/mosquito ditches that run through the lots before they reach their discharge points outside of the proposed lot lines. The Petitioners are owners of single-family homes within the subdivision to the east known as Whispering Pines Forest, 5th Addition. These property owners filed a Petition in which they disputed the appropriateness of the Notice of Intent to Issue filed by DER on August 21, 1990. In support of their position, the Petitioners identified a number of areas of controversy they contend should cause DER to reverse its preliminary decision to grant the "dredge and fill" permit on this project. Elimination of Natural Drainage The first area of controversy is the Petitioners' contention that their interests are substantially effected by the elimination of natural drainage from their subdivision into the uplands referred to as Egret Woods Subdivision. The entire area was owned by the same developer prior to the creation of Whispering Pines Forest 5th Addition. Essentially, the Petitioners allege that a subservient estate was created on these adjacent lands for their surface water drainage purposes which the proposed development eliminates. A review of the Notice of Intent to Issue reveals that culverts are to be placed in two of the open conveyance ditches currently transporting surface water runoff from Whispering Pines Forest 5th Addition through the uplands of Egret Woods into the wetlands. While this proposed change in the means of conveyance of the surface water may not affect the volume of water conveyed, it could adversely effect the quality of the water at the discharge points into the wetlands. At hearing, the Petitioners were unable to clearly articulate their concerns about this water quality issue. However, it is intricately interwoven into the surface water management issues. The water quality concern was obliquely referred to in the Biological and Water Quality Assessment Report where DER's application appraiser commented that the proposed conservation easements and the mitigation plantings, which replace the high marsh removed for lot reconfiguration, are sufficient to offset the potential adverse impacts of the requested fill and culvert changes to the existing water quality at the project site. Although this particular water quality issue was properly addressed by DER in its review of the permit application, it was not clearly set forth in the Notice of Intent to Issue. There is no way for a person whose substantial interests are affected by the proposed permitting decision to determine that DER had considered mitigation measures to prevent this adverse effect. A decrease in surface water quality would have been caused by the marsh elimination and the placement of culverts if the marsh had not been replanted, and other mitigative measures had not occurred at the locale. The Petitioners properly requested a formal administrative hearing to address surface water management issues as DER's consideration of the matter was not made clear to them in the Notice of Intent to Issue. The written report that discusses water quality as it relates to the mitigation plan was provided to Petitioner's post-hearing, after a copy of the written appraisal was sent to the Hearing Officer and all parties by DER. Planned Roadway The second area of controversy is the Petitioner's concern about the effects of the planned roadway on their properties. As the planned roadway involves the county, it is not a matter considered in the dredge and fill permit. Neither DER nor the Hearing Officer has subject matter jurisdiction. The Petitioners did not pursue this area of controversy or the road location at hearing based upon the Hearing Officer's ruling that it was not relevant to this permit review. High Water Mark and the Setting of the DER Jurisdictional Line The third area of controversy raised by Petitioners involves their collective concern about a variance in the height of the Mean High Water Line on the property on different documents presented to different agencies. The current survey for DER completed by the surveyor shows the Mean High Water Line at 1.16, while the survey submitted to Pinellas County in 1981 from the same surveyor reads the Mean High Water Line at 1.25. This was explained at hearing by the surveyor. It was his opinion as a professional surveyor that there is no basic difference between these two mean high water lines. Since the survey to the county in 1981, the Mean High Water Line has varied between 3 - 3 1/2 feet in some areas. The same methodology and simple mathematical formula was used by him during the two different surveys which were about eight years apart. The difference in the two surveys is within the tolerance level accepted within the industry and needs no further reconciliation. As a correlative issue, Petitioners raise a concern about the change in DER's jurisdictional line on various documents involving this same site over a number of years. DER's jurisdictional lines have changed since the "Hendersons Wetland Act" enacted on October 1, 1984. The jurisdictional line as depicted on this permit application was established by dominant plant species as defined in Rule 17-301.400, Florida Administrative Code, just prior to the application submission. This was the correct way to determine jurisdiction on the property at this particular point in time. Although the mean high water line may have been determinative of DER's jurisdiction on earlier permits, only the current law applies to the facts of this case. DER reviewed the jurisdictional lines as depicted on the property by Respondent Telese's consultant and found them to be properly placed during the processing of the permit application. Historical DER jurisdictional lines and permit reviews are irrelevant to this permit review as it is based upon the agency's current rules the applicable statutory criteria, and current site conditions. Fill Calculations The fourth area of controversy involves the Respondent's request to place fill on the site. When Petitioners used an engineer's scale to measure the areas to be filled on the permit drawings, their volume calculations reveal that more fill will be needed than represented on the permit application. Petitioners are concerned that this error could cause DER to approve a permit which does not accurately depict site conditions. The actual fill calculations were done by the professional engineer with a computer model based upon average elevations, depth and area. In his professional engineering opinion, his calculations were accurate, which was given great weight by the Hearing Officer. The drawings used by the Petitioners to calculate the required fill for the area were pictorial communications of what the Respondent Telese intended to accomplish at the site. These drawings were designed for descriptive purposes only and were not scaled to the extent that they could be accurately used for fill calculations in the manner applied by Petitioners. The computer modeling used by the professional engineer was the more prudent approach to the on-site fill requirements. De Novo Permit Review Although the wetlands resource permit requested by Respondent Telese is commonly referred to as a "dredge and fill" permit, there is no dredging associated with the project. The proposed placement of fill in the high marsh area of tidal wetlands on the property and the culvert placement requires construction activity in Class III Waters. Water quality impacts to the area will be a short term problem as water turbidity should take place only during construction. Specific conditions regarding construction techniques have been placed in the permit as permit conditions to minimize the impacts. There is no factual dispute as to whether the proposed conservation easement, the replacement and enlargement of the high marsh in another location, the removal of exotics such as Brazilian Pepper trees, and the planting of black mangroves will sufficiently mitigate the adverse impacts on water quality and the public interests at the proposed development. Without the replacement of the disturbed high marsh with high marsh plantings at a 1.91:1 ratio, the enhancement of the property through exotic removal, and the conservation easements at a 132:1 ratio, the Respondent Telese is unable to provide reasonable assurances that the project is not contrary to the public interest under the statutory criteria established in Section 403.918, Florida Statutes. The proposed project will not adversely affect the public health, safety, or welfare or the property of others. The flooding anticipated by the Petitioners is speculative, and has not been directly related to the fill placement and the culverts in the two conveyance/mosquito ditches. Conservation of fish and wildlife and their habitats, will not be adversely affected due to the high marsh replacement and the fact that the area provided only marginal wetland habitat prior to the permit application due to the invasion of exotics at the site. Any impact from the proposed project on this public interest criterion is offset by the mitigation plan. The project will not adversely affect fishing or recreational values or marine productivity in the vicinity of the project. The proposed plantings of black mangroves and the removal of exotics, along with the new high marsh swamp should enhance the productivity of the area. No future projects of a similar nature can be developed at this locale due to the conservation easements the Respondent Telese has consented to provide over the remaining undeveloped property owned by him in the area. These easements will allow the Department to limit and control activities that may be undertaken in these tidal waters to prevent degradation of the site from an environmental standpoint. The mitigation planting schedule provides reasonable assurances that water quality standards will not be violated in the area as a result of culvert placement in the two conveyance/mosquito ditches that transport surface water to Class III waters of the state. Balancing of Interests In the "dredge and fill" permit application appraisal, site review, and Notice of Intent to Issue, DER considered and balanced all of the required statutory criteria to determine that the project is not contrary to the public interest or applicable water quality standards. Area of Controversy All of the areas of controversy raised by the Petitioners which are within the Division of Administrative Hearings' jurisdiction, have been sufficiently met by the reasonable assurances of Respondent Telese and the permit conditions required by DER. Based upon the evidence presented at hearing, it is concluded that the harms anticipated by Petitioners will not occur. Recommendation Regarding the Assessment of Attorneys Fees and Costs Petitioners did not participate in this proceeding for an improper purpose. The Notice of Intent to Issue was vague as to how interests were balanced and how the mitigation would offset the adverse impacts that concerned Petitioners. The petition was filed and prosecuted in good faith and addressed legitimate concerns of concerned citizenry who reside on adjacent lands.
Recommendation Based upon the foregoing, it is recommended: That a Final Order be entered approving Respondent's Telese's dredge and fill permit number 521715273, pursuant to the Notice of Intent to Issue filed August 21, 1990. That Petitioners should not be assessed attorney fees and costs as they did not participate in these proceedings for an improper purpose.

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.
Recommendation Based upon the findings of fact and conclusions of law recited above, it is recommended that petitioner's application for a permit to connect his canal to the Caloosahatchee River be DENIED. Respectfully submitted and entered this 22nd day of December, 1976, in Tallahassee, Florida. DIANE D. TREMOR Hearing Officer Division of Administrative Hearings Room 530, Carlton Building Tallahassee, Florida 32304 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of December, 1976.
Findings Of Fact On December 9, 1982, Petitioner filed with Respondent a dredge and fill permit application to remove gates and wing-walls from a double-lock canal system presently installed at the Palmetto Point Subdivision in Lee County, Florida, adjacent to the Caloosahatchee River. On January 6, 1983, Respondent sent a "completeness summary" to Petitioner, along with a letter advising Petitioner that its permit application was incomplete, and requesting additional information. Petitioner responded to the January 6, 1983, completeness summary by submitting additional information to Respondent on or about February 23, 1983. On March 21, 1983, Respondent sent a second completeness summary requesting further additional information from Petitioner. By letter dated May 18, 1983, Petitioner's attorney advised Respondent that submission of additional requested hydrographic information and water quality data was not justified. The letter further advised that Petitioner intended to rely on the information already submitted, and requested, pursuant to Section 403.0876, Florida Statutes, that Respondent begin processing the permit application. The letter further indicated that petitioner was submitting under separate cover a request that Respondent apply the "moderating provisions" of Rule 17-4.244, Florida Administrative Code, to the application. The aforementioned rule is entitled "Mixing Zones: Surface Waters." Also on May 18, 1983, Petitioner's counsel sent another letter to Respondent requesting the aforementioned "Mixing Zone." The letter requested the "maximum mixing zone" allowed under the applicable Provisions of Rule 17- 4.244, Florida Administrative Code. Petitioner had not requested a mixing zone be applied to the permit application prior to the request contained in its May 18, 1983, letter. By letter dated June 17, 1983 Respondent, in response to Petitioner's May 18, 1983, letters, advised that: The additional information [which] was received on May 19, 1983, was reviewed; however, the items listed on the attached sheet remain incomplete. Evaluation of your proposed project will continue to be delayed until we receive all requested information. Respondent's June 17, 1983, letter included a completeness summary, which asked for additional information, including the following requests concerning mixing zones: Your request for a mixing zone is applicable pursuant to F.A.C. Rule 17-4.244(6). Please provide a map indicating the outermost radius of the mixing zone (no more than 150 meters) and the period of time required. The completeness summary acknowledged Petitioner's refusal to supply additional information concerning hydrographic data and water quality information, and indicated that Respondent would evaluate the project accordingly. By letter dated August 29, 1983, Respondent advised Petitioner that it had been 73 days since notification of the incompleteness of the permit application with regard to the mixing zone request. This letter requested Petitioner to advise Respondent if it wished to withdraw the application, request additional time, or discuss questions regarding the application. The Petitioner did not respond to this communication. On September 9, 1983, Petitioner's attorney forwarded a letter to Respondent requesting a default permit pursuant to Sections 120.60(2) and 403.0876, Florida Statutes. Until this letter, other than a prior oral communication on September 2, 1983, notifying Respondent that the default request was forthcoming, Petitioner had not contacted Respondent concerning the permit application since its May 18, 1983, letters. On October 13, 1983, Respondent advised Petitioner by letter that the mixing zone request constituted a revision of the application and that the information received to evaluate the mixing zone request was incomplete. Petitioner was also advised that since the additional information requested had not been received, the application remained incomplete and Petitioner was not entitled to a default permit. Whether or not a mixing zone is applied to a permit application is significant because it determines where state water quality standards must be met, either adjacent to the proposed project, or up to 150 meters away from the project location. Under Rule 17-4.244(6), Florida Administrative Code, the 150 meter radius is measured from the point of generation of turbidity or pollution. Since the two locks to be removed were 80 feet apart, it was unclear whether Petitioner intended the point of generation for measuring the radius of the mixing zone to be the northern lock, the southern lock, or some other point. It is equally unclear whether Petitioner intended the mixing zone to extend south into the canal as well as north into the Caloosahatchee River. Petitioner never contacted Respondent to clarify the dimensions of the mixing zone being sought, even after Respondent requested a map indicating the outermost limits of the mixing zone in the June 17, 1983, completeness summary.
