Findings Of Fact On October 15, 1982, Hal Thomas Reid Associates applied for a septic tank permit to serve a 16-room motel. On February 2, 1983, this application was amended to a 5,800 gallon septic tank to serve a 32-unit condominium and office. The lot on which this drain field is to be located is 70 feet by 100 feet. When the application was filed, the lot was inspected by the Citrus County Health Department. The elevation of the land averaged 2.5 to 2.9 feet above mean sea level. The 10-year flood plane in this area is 4.9 feet. Occasional high tides inundate this area; however, the water drains off rapidly and no one testified that water ever remained standing as long as seven consecutive days. Usually the water drains off in less than 24 hours. On March 1, 1983, an extremely high tide flooded this area and roads in the vicinity to a depth of approximately one foot. This water remained on the site less than 24 hours. The site is not located adjacent to state waters, is not an area designated as wetlands, and is without the dredge and fill permitting jurisdiction of the United States Army Corps of Engineers and the Florida Department of Environmental Regulation (Exhibits 20 and 21). By adding five feet of fill to the site, the bottom of the gravel below the drain pipes will be above the 10-year flood plane. The drain field capacity is adequate to handle the flow from 33 bathrooms of residential units. In approving this permit, the Citrus County Health Department used the 150 gallons per day discharge for residential units rather than the 100 gallons per day discharge from a motel unit. The water table at this location is two feet above mean sea level. This is determined by the elevation reached at high tides for 14 consecutive days. As a condition to Citrus County withdrawing as an intervenor in these proceedings, Applicant agrees: To revegetate and restore any alleged wetlands affected by the permit to a like or similar condition; To install three shallow draft monitor wells around the drain field towards the wetlands area adjacent to the site and towards Woods 'n Waters subdivision, establish an existing level of bacteria count prior to the activation of the septic tank, and to monitor said wells through the Citrus County Health Department on a quarterly basis; and In the event any monitor wells shall test at an unsatisfactory level, Applicant will forthwith correct this condition to the satis- faction of the Citrus County Health Department. This application meets all of the code requirements of Chapter 10D-6, Florida Administrative Code.
The Issue Whether Michael Chbat's 2008 application for a Wetland Resource Permit (WRP) to construct a culvert extension across his property in Walton County, Florida, should be approved?
Findings Of Fact La Grange Bayou Estates La Grange Bayou Estates is a residential subdivision in Freeport, Walton County, Florida. The subdivision lies to the north of the shoreline of Choctawhatchee Bay. It can be viewed as divided roughly in half between bayfront lots south of an east-west road that transects the subdivision and lots that are north of the road. The subdivision is platted and the plat is in the public records of Walton County. Filed with the Clerk of the Circuit Court in and for Walton County, Florida, on September 15, 1982, the plat ("the 1982 Plat") shows 29 residential lots in the subdivision as of that date. See Petitioner's Ex. 6. Lots 1 through 16, according to the 1982 Plat, are the bayfront lots, south of a 40-foot wide road designated as a private road in the plat. That road is now known as Alden Lane. Wetlands over which the Department has jurisdiction ("jurisdictional wetlands") comprise much of the southern portion of bayfront lots and the drainage easement. Among the bayfront lots are both Lot 9 which belongs to Mr. Chbat and Lot 8 which belongs to Mr. Sheehey. A 50-foot easement lies between Lot 9 and Lot 8 and is described more fully below. The presence of jurisdictional wetlands on Mr. Chbat's lot over which he hopes to install the culvert extension requires that he obtain a WRP. To the north of Alden Lane are lots numbered by the 1982 Plat as 17 through 29. The lots are served by Alden Lane and, in what is roughly the northeast quadrant of the subdivision, by two other roads. One of the roads is shown on the 1982 Plat as a "40' PRIVATE ROAD." Id. A 2006 aerial photograph introduced into evidence by Chbat designates the road "unnamed." See Chbat Ex. 5. The other is designated as a "graded county road," on the 1982 Plat. By 2006, it had come to be known as Beatrice Point Road. Id. Beatrice Point Road transects a pond that runs roughly 340 feet (excluding about 30 feet of roadway) in a northeasterly direction from Alden Lane to the southern edge of an area north of the subdivision shown on the 1982 Plat to be un-platted. The pond is most likely the result of a "borrow pit" dug in order to obtain fill for the construction of the roads when the subdivision was initially developed. The southern boundary of the pond lies along approximately 140 feet of Alden Lane's northern edge. The pond is across the street from Lots 9, 10 and 11 of the subdivision. The pond is also not far northeast of the 50-foot easement (the "Drainage Easement") between Lots 9 and 8. The Drainage Easement The Drainage Easement is just to the west of Lot 9. It is noted on the 1982 Plat as a "50' EASEMENT (PRIVATE)." Id. The 50-foot wide Drainage Easement runs the length of the western boundary of Lot 9 and the length of the eastern boundary of Lot 8. The northeast corner of the Drainage Easement is approximately 30 feet from the southwest corner of the pond separated from the pond by the roadway of Alden Lane. The eastern boundary of the Drainage Easement is 226.37 feet in length, or if taken to the middle of Alden Lane, 246.3 feet. The western boundary is 206.13 feet long or if taken to the middle of the road, 226.65 feet. The purpose of the Drainage Easement, as is evident from its denomination in this recommended order, is drainage. As Mr. Street definitively put it at hearing, it is "now and always has been intended to drain stormwater to the [B]ay." Tr. Vol. III at 179. Mr. Street's opinion of the function of the Drainage Easement is supported by drawings submitted by Mr. Chbat as part of the WRP application. The drawings show that the Drainage Easement's function is facilitated by three culverts north of the Easement (referred to during the hearing as "pipes") each of which is intended to direct stormwater at its point of discharge toward the Drainage Easement. See Chbat Ex. 1. One of the culverts ("the Drainage Ditch Culvert") serves a drainage ditch that is to the north of the Easement and Alden Lane. According to the drawings, the drainage ditch lies on the other side of the "un-named road" from the pond, that is, to the west of the pond, and is some 40-to-50 feet north of the Drainage Easement. The Drainage Ditch Culvert extends from the ditch to the southern half of Alden Lane from where it appears from the application's drawings that stormwater would be conveyed to the western side of the Drainage Easement along it's border with Lot 8 and on toward the Bay. In fact, it is a functioning culvert that "conveys water from a swale on the side of the road into the [D]rainage [E]asement." Tr. 64. Once in the Drainage Easement, according to the drawings, the water should flow into the Bay out of a "cut," id., that is labeled on the drawings as an "existing trench." See Chbat Ex. 1. The trench, however, has been filled in with sand by tidal activity or sediment deposited by stormwater or both. The trench has not been maintained, and it no longer exists. The other two culverts (the "Pond Culverts") lie east of the Drainage Ditch Culvert. They catch overflow from the pond caused by stormwater and convey it under and through Alden Lane toward the Drainage Easement. The westernmost Pond Culvert (the "Western Pond Culvert") appears to terminate in Alden Lane near its southern edge just north of the Easement. At the time of hearing, however, it was not functioning properly. "[I]t is full of sand and silted up . . .", tr. Vol. I at 58; "[t]he pipe to the west is clogged and it is not functioning." Tr. Vol. I at 64. It is also at an elevation that would keep it from serving drainage purposes in all but the most severe storm events. See Chbat Ex. 9 at 22. The other Pond Culvert, (the "Eastern Pond Culvert") terminates in the northwest corner of Lot 9 at the border between Lot 9 and the Drainage Easement about 10 feet southeast of the terminus of the Western Pond Culvert. The Eastern Pond Culvert is the culvert with which the Amended Permit is concerned, that is, it is the culvert to be extended by the permit. Calling it a "pipe," Mr. Street offered the following about the assistance the Eastern Pond Culvert offers in conveying stormwater into the Drainage Easement and down to the Bay: There is currently a pipe that discharges into that easement. There . . . was an attempt to place the water from the . . . pond into the easement. And the natural flow of water on this entire property from the road to the [B]ay is north to south. At some point, at least 2004, that drainage easement contained a conveyance at its southern end that would safely discharge stormwater to the [B]ay. Tr. Vol. III at 179-80. Petitioner Sheehey and Lot 8 Thomas Sheehey is the owner of Lot 8, where he has a residence in which he makes his home. He has lived in the residence approximately five years. During that time, Mr. Sheehey has fished in the Bay and enjoyed the use of his kayak and his waverunner on the Bay. He also enjoys "sitting down having a cup of coffee and looking at it," tr. vol. III at 151, as well as watching his neighbors fish. The recreational uses to which he puts the Bay is the reason he chose to purchase a bayfront lot in La Grange Bayou Estates. Over the period of time that he has resided on Lot 8, Mr. Sheehey has observed the effects of rain events on his lot and well as lots close to Lot 8. He has also taken pictures of his property and the near-by lots. Among the photographs were four taken after rain events or "after a wet period," tr. vol. III at 88, at some point in the last four years. The four photos were introduced as a composite exhibit, Petitioner's Ex. 2, with each photograph marked as 2A, 2B, 2C or 2D. Mr. Sheehey could not specify when the pictures were taken in the past four years other than that if a picture had a certain dock in it, then it was taken after January of 2009. Petitioner's Ex. 2A was taken from Mr. Sheehey's lot looking toward the Bay. It shows an area of the lot under water separated from the Bay by a ridge. Petitioner's Ex. 2B is a picture taken from Lot 13 looking west across Lots 12, 11, 10, 9 "down through 8." Tr. Vol. III at 86. Much of what is photographed is among trees and vegetation emerging from water standing above the surface of the soil. Petitioner's Ex. 2C is a picture taken from Alden Lane looking south across Mr. Chbat's property. It shows a wide swath of water that extends from the road across most of the property to the Bay. The water is either in a swale or constitutes overflow outside the swale. The most recent of the four is Petitioner's Ex. 2D, which shows the dock referred to by Mr. Sheehey that was built in early 2009. It is a picture taken from Lot number 13 toward the west through Lots 12, 11, 10, 9. Like the others, it shows vegetation standing in water to the north of the Bay. Taken together, the four pictures in Petitioner's Exhibit 2 demonstrate that significant portions of the lots depicted are under water following sufficient amounts of recent rain. The four photographs that comprise Petitioner's Exhibit 2 are not the only photos taken by Mr. Sheehey that were introduced into evidence. Three other photographs of Mr. Sheehey's, Petitioner's Exhibits 7A, 7B and 7C, were admitted following testimony about them from a long-time observer of the flow of water from Alden Lane to the Bay. A Long-time Observer Thomas Eugene Cummins had lived in La Grange Estates "[t]wo months shy of 20 years," tr. vol. III at 7, at the time of his testimony. His house was the fourth to be constructed in the subdivision. Over the two decades of his residence, the pond between Alden Lane and the property north of the subdivision has been in existence. Consistent with the drawings submitted to DEP as part of the application, when asked where the pond overflows today, Mr. Cummins answered "it drains under Alden Lane on to Mr. Chbat's lot." Tr. Vol. III at 8. Asked by Mr. Chesser at hearing, "When the water comes out of the pond, is it possible to know where it spreads?"1/ Mr. Cummins testified: On really heavy rains, I have watched the normal color of the pond change from its dark blackish gray color into the reddish color that the clay has washed down into it, flow under Alden Lane and on to Mr. Chbat's lot, and then proceed west through the wetland on lots eight, seven, six, and my five, and turn reddish color even in my lot. Tr. Vol. III at 9-10. Mr. Cummins knew the source of the "red color" of the stormwater: red clay introduced to La Grange Estates by the County half a decade earlier. Mr. Cummins testified: Beatrice Point Road, which is the road that runs over the pond, about five years ago the county did some repair on the road and actually put red clay in certain spots to even it out. Tr. Vol. III at 9. Prior to the county's work on the road referred-to by Mr. Cummins, there had been no red clay in the neighborhood. Alden Way, for example, has no red clay. It is a road composed of shell. The only red clay in the subdivision is that which is on Beatrice Point Road. The water that runs onto Mr. Cummins' lot following a heavy rain rises to as much as 12 inches.2/ The water rises as high as it does because it is held back by a naturally-occurring land formation between the Bay and Mr. Cummins property. This geo-formation was referred-to at hearing as the ridge line or the ridge. The Ridge The Ridge was described by Mr. Cummins as a vegetated mass of earth that most of the time, even in heavy rains, sits above the water that collects on the bayfront lots of La Grange Estates. The Ridge prevents a substantial amount of stormwater runoff from entering the Bay from the wetlands on the southern portion of the subdivision's bayfront lots. For that reason, the ridge is called "our upland,3/" tr. vol. III at 13, according to Mr. Cummins. Between Lot 9 and Lot 5, the ridge varies in width "anywhere between 10 feet . . . up toward Mr. Chbat's lot, down to [Mr. Cummins'] lot where its around 30 or 40 feet [wide.]" Id. (It may extend, in fact, across all of the bayfront lots.) The ridge meanders not far from the shoreline. Id. In some places it is as narrow as five feet. The height of the ridge varies as well from as low as one foot to as high as two and half feet. Mr. Street also testified about the Ridge, referring to it in his testimony as a "ridge line": Now, there is a ridge line, and there's been a lot of testimony about this ridge line, that it exists across all of the lots. My testimony was, essentially, related to the review that I did, which was primarily associated with lots eight and nine, and the drainage easement between them. And from what I can tell, the elevation of that ridge line is give or take three. Elevation three, not a height of three. An elevation of three. It could be lower, and perhaps, is higher. And its subject to the vagaries of a number of factors, flow of stormwater, wave action, tidal influence, and the like. And these accretions and depositions of sand over time change that ridge line. And sometimes, it opens up. And sometimes it may not have a natural opening, depending on where you are along that entire stretch of beach. * * * [T]o the extent there is an opening in that ridge line, water will flow naturally to the bay. Tr. Vol. III at 180-181. An "east west flow of water," tr. vol. III at 181, along the bayfront lots, that is, a flow of water either in an easterly direction or a westerly one is contrary to the flow from Alden Lane north of the lots to the Bay south of the lots. Whether flowing east or west, the water in the southern portions of the bayfront lots is "controlled by the ridge line." Id. In other words, stormwater that flows from north to south across the bayfront lots, including Mr. Chbat's and the Drainage Easement, is going to collect and begin to flow from east to west or west to east at some point north of the Ridge before it drains into the Bay. The only exception to east-west flow, as made clear by Mr. Street, is when and if there is an opening in the Ridge that allows the water otherwise held back by the Ridge to flow southward into the Bay. The east-west flow of the water along the Ridge was described at hearing as "unnatural." Id. In fact, it is not un-natural. The Ridge is the cause of the east-west flow and, as Mr. Street testified, the Ridge is the result of natural processes such as tidal influence, wave action, accretion and deposition of sand.4/ The Ridge is shown in Petitioner's Exhibit 7A,5/ another photograph taken by Mr. Sheehey. The ridge as shown in the picture is well vegetated and above water to its north and higher than the Bay to its south. It is quite clear that if there is no opening in the ridge to the Bay, stormwater north of the ridge is forced to flow in east-west directions and is prevented from flowing into the Bay. Petitioners' Exhibit 7B is a photograph of the southern terminus of a swale (see paragraphs 40 - 49, below) on Mr. Chbat's property. It shows the swale cut through the Ridge. Water, however, does not appear to be running from the end of the swale into the bay. It appears that the end of the swale is a few feet from the Bay separated by a narrow sandy area on the shore. Nonetheless, the photograph shows that there is potential for stormwater to flow from the swale when the swale has more water in it. Petitioner's Exhibit 7C is a picture of the pond6/ across the street from Mr. Chbat's Lot 9. Mr. Chbat and Lot 9 Michael Chbat is the owner of Lot 9. He purchased the lot "[t]o build a house on it." Tr. Vol. I at 22. Because he has family close by (in Fort Walton Beach), Mr. Chbat expects to use a house built on the lot for weekend visits. His ultimate aspiration is to live in a house on Lot 9 after he retires from his position as a construction engineer with the City of Tallahassee. At hearing, Mr. Chbat described Lot 9 on the day he bought it: "the lot was overgrown. It drained from north to south. It had water standing on it. And it had a pipe [the Eastern Pond Culvert] on the northwest corner discharging." Tr. Vol. I at 23. He also described the state of the lot at the time of hearing. The Eastern Pond Culvert on the northwest corner was still there. The lot had been cleared to some extent to rid it of invasive species. Overgrown vegetation was trimmed or cleared to make room for a driveway permitted by the Department and "a parking pad in the front area of it, as well as an access pad in the uplands." Id. A dock had also been constructed from the property into the Bay. The most significant difference between the lot at the time of purchase and the lot at the time of hearing for purposes of this proceeding is that the lot now has a swale (the Swale) that runs from the point of discharge of the Eastern Pond Culvert "all of the way to the bay area." Id. The Swale The Swale was put in sometime after March 20, 2007, as the result of a Settlement Agreement fully executed on that date "By and Between Michael Chbat and Thomas L. Sheehey." Petitioner's Ex. 10. The Settlement Agreement followed events that commenced in 2004 when Mr. Chbat filed an application (the "2004 Application") with DEP for a WRP primarily to construct a house and a boardwalk leading from the house on Lot 9 to a dock in the Bay. The 2004 Application also proposed the extension of the Eastern Pond Culvert with a "pipe" along the western boundary of Chbat's property in a manner substantially similar to the culvert extension allowed by the Amended Permit that is the subject of this proceeding. On October 28, 2005, DEP proposed that the 2004 Application be granted. The permit (the "Proposed Original Permit") was assigned No. 66-0235320-001-DF. See Petitioner's Ex. 10, at 2. The Proposed Original Permit was challenged by Mr. Sheehey when he "filed a Petition for Administrative Hearing contesting certain action authorized under the [Proposed Original] Permit . . . specifically the relocation of a drainage pipe . . . ." Petitioner's Ex. 10, at 2. After referral of the petition to DOAH, Mr. Chbat and Mr. Sheehey wrote in the Settlement Agreement that they had "determined that it is in their best interests to settle this matter amicably pursuant to the terms hereafter". Id. Among the terms is that Chbat would file an Amended Application. See id. The agreed-to amendment to the 2004 Application was attached to the Settlement Agreement as Exhibit "A," a drawing of a "Drainage Swale Plan," produced by Genesis Group for Mr. Chbat. The drawing depicts a swale that runs from the discharge point of the Eastern Pond Culvert nearly the full length of the western boundary of Lot 9 to the Bay. See Exhibit "A" to Petitioner's Ex. 10. The Swale was designed to take the place of the 2004 Application's proposal for a "pipe"7/ attached to the point of the discharge from the Eastern Pond Culvert. The Settlement Agreement received the support of DEP because the Department believed that a swale would assist in improving the quality of the stormwater discharged to the Bay over the untreated discharge from the end of the "pipe." Pursuant to the terms of the Settlement Agreement the 2004 Application was amended. The Department amended the Proposed Original Permit accordingly and final agency action was taken with the issuance of a permit to Mr. Chbat (the "Final Original Permit") found in DEP Permit File No. 66-0235320-001- DF. Installation of the Swale The Swale was installed, but it did not work as intended. The result of the Swale's installation was more water on the lot rather than less. Mr. Chbat described the after-effects of the Swale: "it started bringing more water to the lot . . .". Tr. Vol. I at 31. The increased amount of water is the result of several factors, one of which is tidal influence: the tide from the Bay pushes water into the Swale. "[A]bout halfway on the swale . . . that water from the bay was meeting the water from the pipe . . .". Id. The water from the Bay tide and the stormwater conveyed by the Swale would meet at "about the middle of the span of the swale." Id. The result was "a lot more water," id., on the lot. Mr. Thomason confirmed Mr. Chbat's assessment that the reason the Swale did not function as effectively as necessary is tidal flow onto Lot 9 from the Bay particularly from high winds. But tidal flow onto Lot 9 and the interruption in the discharge of stormwater through the Swale are not the only problems. There is also a maintenance factor that accompanies tidal flow: sand deposition. Mr. Thomason elaborated: "[D]uring storm events or [just normal] wave action in the bay, sand is brought back up on to . . . the sandy area at the end of [Lot 9] next to the [Bay.]"8/ Tr. Vol. I at 62. The influx of sand onto Lot 9 is not just a problem for adequate functioning of the Swale. The Drainage Easement has "the same problem." Id. Both the Swale and the Drainage Easement are plagued by deposition of sand pushed landward by normal tidal influences and storm events. Maintenance of the Swale and the Drainage Easement, therefore, would assist the drainage of stormwater into the Bay. The tidal influence and maintenance issues that Mr. Chbat encountered with the Swale led him to apply for a different and new permit. That application was filed in 2008. The 2008 Application Mr. Chbat filed a "Joint Application for Works in the Waters of Florida" with DEP on August 1, 2008 (the "2008 Application"). See Chbat Exhibit 1. The work to be approved was similar to the work originally proposed in the 2004 Application in that both applications proposed installation of a "pipe" to be fixed to the discharge point of the Eastern Pond Culvert that would run along the western boundary of Lot 9 toward the Bay. A description of the work is contained in Section 10 of the 2008 Application: "Extension of an existing stormwater pipe within a private lot approximately 150 feet. The slope for the proposed pipe extension will be at minimum so that stormwater will be treated further, and minimizing erosion." Chbat Ex. 1 at 3. After the filing of the 2008 Application, Mr. Chbat learned that Mr. Sheehey objected to the newest Chbat proposal because he believed 150 feet is not lengthy enough to clear the Ridge. See Chbat Exhibit 2. In order to cure the objection, Mr. Chbat proposed a modification to the 2008 Application. He attached a "sealed and signed drawing," id., to a letter dated September 18, 2008, that he submitted to DEP. The drawing shows the extension to be 177 feet, 27 feet more than initially proposed by the 2008 Application. The additional 27 feet was intended to ensure that the discharge would be directly into the Bay in order to "eliminate any possible run-off impact to adjacent properties." Id. The modification was accepted by DEP." See exhibit number 19/ attached to the Amended Permit, Chbat Exhibit 4. There was conflicting evidence in the proceeding on whether the outfall from a culvert extension of 177 feet will be bayward of the Ridge. The issue was put to rest by Mr. Street’s testimony in rebuttal at the hearing. See Tr. Vol. III at 194 and 203-4. His testimony establishes that the point of discharge at the end of the culvert extension will clear the Ridge so that the discharge will be directly into the Bay. The Mound The culvert extension is designed at an elevation and with cover (presumably sod). The extension runs through jurisdictional wetlands and segments them. It does not, however, isolate any portion of the wetlands. The wetlands on Mr. Chbat's property and those to the immediate east and west of it, therefore, will retain their status as jurisdictional wetlands should the extension be installed. With its sod cover, the culvert extension will be a mini-berm (or a "mound" as Mr. Street called it) at an elevation of 17 to 18 inches above grade. Water that pools to its west will no longer be able to flow eastward of the mound (except rarely under the most extreme weather events.) Conversely, water that collects to its east will no longer be able to flow westward of the extension. It would have to be a severe storm event for water to rise above the mound. Mr. Chbat has never seen water rise to 18 inches above grade and Mr. Cummins testified the highest water ever gets on his property is roughly 12 inches. The Department approved the 2008 Application as modified to lengthen the extension to 177 feet and issued the Amended Permit. But an incorrect and critical assumption was made during review of the application that related to the mound. Review of the 2008 Application During his review of the application, Mr. Street, as DEP's stormwater engineer, assumed from the drawings that the Drainage Easement is functional.10/ The assumption was expressed in Mr. Street's testimony in the Department's case-in-chief: Q [D]id you determine whether the pipe, as it would be mounded . . . [the culvert extension covered in sod] . . . would create problems for storm water flow? A I looked at that. There were two conclusions that I drew. One was that the mound would create a higher water elevation on the Chbat property east of the mound, but would not create standing water west of the mound extending into the [Drainage E]asment . . . . Which on the drawings that I reviewed showed an existing trench at the south end of that easement. And it was my opinion that any water that fell west of the mound would exit through the easement. Tr. Vol. II at 92 (emphasis added.) Mr. Street's assumption that water would not pool to the west of the mound in the Drainage Easement and toward Mr. Sheehey's property was contradicted by Mr. Sheehey's stormwater engineer, Mr. Porterfield. THe Porterfield Testimony and Support for It at Hearing The testimony at hearing of Mr. Porterfield, who conducted a site visit, established the opposite of what Mr. Street assumed. The volume of stormwater runoff that pools east of the mound, that is, water on Lot 9, will not be as great as the volume as the water that pools west of the mound. Water that would have flowed onto Lot 9 from the Eastern Pond Culvert will flow directly to the Bay via the culvert extension. The extension will also protect the Drainage Easement and Lot 8 from water that would have flowed from the Eastern Pond Culvert onto that property. But there is a significant difference between stormwater to the west of the extension and to the east. To the extension's west, the Drainage Easement and Lot 8 will have to contend with stormwater from the Drainage Ditch Culvert, the culvert north of Alden Lane that does not convey stormwater from the pond but that like the Pond Culverts has a discharge point directed at the Drainage Easement. How often and to what extent pooling of stormwater will occur west of the mound due to its presence is difficult to determine on the state of this record.11/ No studies or analyses of the likelihood and severity of storm events and the volumes of stormwater runoff that would be produced by them were conducted by any of the stormwater engineers in the case nor were any such analyses done with regard to pooling caused by the presence of the covered culvert extension. The testimony of Mr. Porterfield, however, and other evidence, demonstrates that that additional collection of water west of the mound caused by the mound will occur following heavy rain. Mr. Street was present in the hearing room throughout the entire hearing, including during the presentation of Mr. Sheehey's case. As Mr. Street candidly testified on rebuttal after he had heard all the evidence: I would also maintain that the drainage easement which has signs of a historical usage as a drainage easement with a trench, in fact, that conveys water safely to the bay, that should be re-established and maintained. That’s what it’s there for.” Tr. Vol III at 181 (emphasis added.) Thus, it became clear to Mr. Street after listening to all the evidence in the case that the Drainage Easement has not been properly maintained. The trench that was expected to carry stormwater toward the Bay no longer exists. In short, the testimony of Mr. Street, for all his many strengths as a witness, falls short of supporting the position of the Department and Mr. Chbat. Having never visited the site,12/ he approved the project on the basis of drawings that do not conform to the on-site physical reality. When presented with the evidence at hearing that the Drainage Easement is not functioning, he championed re-establishment and maintenance of the Drainage Easement. Mr. Chbat placed part of the Swale's functionality problem on the tide pushing stormwater northward but his case also recognized the maintenance problem caused by deposition of sand that besets the Swale. Mr. Thomason, moreover, recognized that the Drainage Easement has the same maintenance issue. Mr. Chbat's stormwater engineer testified During storm events or just normal wave action in the bay, sand is brought back up on to. . . the sandy area at the end of [Chbat's] lot next to the water. And so that . . . tends to inhibit the natural flow down the swale . . . we have the same problem on the drainage easement . . . where sand builds up in that discharge. Tr. Vol. I at 62 (emphasis added). From this record, it is clear that neither the Swale nor the Drainage Easement functions properly. Their functional status, moreover, is due in significant part to lack of maintenance. It may be that maintenance ultimately will not solve the problem; maintenance efforts to keep the Swale and Drainage Easement clear of the sand deposited by tidal activity may require too much effort for them to be reasonably required. But that evidence was not produced. Indeed, the record was silent as to any maintenance efforts with regard to the Swale by Mr. Chbat or with regard to the Drainage Easement by the owner of the easement. The record is also silent as to whether DEP voiced any concern about the maintenance issues that beset the Swale. It is clear that concern was not raised by the Department in regard to the Drainage Easement until the rebuttal phase of the hearing, since the assumption was made that the easement was properly maintained. Whatever communication may have occurred with regard to maintenance issues among the parties, the Department issued the Amended Permit.13/ The Permit/Authorization Number for the Amended Permit is 66-235320-002-DF.14/ Issued December 19, 2008, the Amended Permit has an expiration date of December 19, 2013. The expiration date coincides with the construction phase of five years on the face of the Amended Permit. See Chbat Ex. 4. Mr. Sheehey Challenges the Amended Permit On January 6, 2009, Mr. Sheehey, pro se, filed with DEP a petition (the "Petition") seeking a formal administrative hearing with regard to "Amended Wetland Resource Permit 66- 00235320-002-DF." Although the Petition makes reference to the Amended Permit, it seeks in the first instance enforcement of the Settlement Agreement that relates to the Final Original Permit. The Petition states: "Petitioner believes that the Florida Department of Environmental Protection has jurisdiction over this matter and should enforce the March 20, 2007 Settlement Agreement which requires that Permittee act in conformance with Exhibit 'A' of the Agreement [the drawing of the Swale]." In the event that DEP declined to enforce the Settlement Agreement, the Petition sets out disputed issues of material fact that relate to issuance of the Amended Permit. The Petition was referred to DOAH on February 19, 2009. One week before the final hearing, the Department filed the motion in limine that is discussed in the Preliminary Statement of this Recommended Order. The motion was granted to the extent that it sought to preclude Sheehey from introducing evidence that supported enforcement of the Settlement Agreement since the 2008 Application, which, while bearing similarity to the 2004 Application, is nonetheless an independent application that should be approved or denied on its own merits without regard to the 2004 Application, the Proposed Original Permit, the Settlement Agreement or the Final Original Permit. The case proceeded to hearing on the remaining issues raised by the Petition: 1) whether Sheehey has standing to contest approval of the 2008 Application; 2) whether Chbat gave the notice required by Section 373.413, Florida Statutes, and 3) whether Chbat's application meets the criteria in statutes and rules for issuance of the Amended Permit. Standing The findings of fact relevant to Mr. Sheehey's standing are found in paragraph 9, above. Notice Notice of the 2008 Application was published in The Defuniak Springs Herald-Breeze, a newspaper published in Defuniak Springs, Walton County, Florida. The notice was published on October 23, 2008. The evidence presented by Mr. Sheehey concerning lack of legal notice consisted of testimony by Mr. Sheehey at hearing in response to questions from his counsel. See Tr. Vol. III at 134. The testimony does not establish that Mr. Sheehey was a person who had filed a written request for notification of any pending application affecting his particular area. The testimony of Mr. Sheehey, moreover, establishes that he was given oral notice of the application by Mr. O'Donnell within four days of its filing. WRP Permitting Criteria To obtain a WRP, an applicant must satisfy the criteria in Florida Administrative Code Chapter 62-312 and Section 373.414, Florida Statutes. These criteria govern a range of topics including water quality. Water Quality15/ Florida Administrative Code Rule 62-312.080 provides that no permit shall be issued unless the Department has been supplied with reasonable assurances that the proposed work will not violate water quality standards. Water that enters the pond spends some amount of time in the pond (residence time) before flowing out. During residence time, solids drop out of the water so that the quality of the stormwater that flows out of the pond is reasonably expected to be better than the quality of the stormwater runoff when it entered the pond. Vegetation surrounding the pond, furthermore, enhances the quality of the water in the pond, whether the water’s source is runoff or rain falling directly into the pond. The water that flows out of the pond north of Alden Lane is “existing discharge.” Tr. Vol. I at 65. It generally made its way to the Bay prior to the Swale. Some of it makes its way to the Bay via the Swale now; some of it outside the Swale as overflow. The culvert extension will convey that discharge to the Bay if the extension is installed. The quality of the water is not significantly less when it discharges to the Bay via the Swale or otherwise from the Chbat property than when it would enter the culvert extension should it be installed. It is true that the Swale would have provided filtration and additional treatment to the discharge from the Eastern Pond Culvert as does the Chbat property in general. But that does not mean that the quality of the culvert’s discharge is a concern. The Swale may have been an option preferable to the extension of the culvert as far as water quality goes but all parties agree that the Swale has failed as a conveyance (albeit Mr. Sheehey maintains that the Swale would work with proper maintenance.) That there is a discharge method that improves the quality of the discharge, such as a swale, does not mean that the discharge to the Bay via the culvert extension is of insufficient quality. None of the parties tested the quality of the discharge from the Eastern Pond Culvert. The Department, nonetheless, offered evidence with regard to its quality. The Department concluded that the quality of the pond and its discharge were not of concern. Had the pond been contaminated to an extent that would have given rise to concerns, moreover, the Swale or the culvert extension as a means of conveying the discharge to the Bay would not have made a “discernible difference.” Tr. Vol. II at 80. The Department provided evidence of assumptions made with regard to the quality of the water that led the Department to conclude that testing of the discharge was unnecessary. Mr. O’Donnell, the Department’s expert in the application of state rules and statutes in wetland resource permitting, detailed the assumptions at hearing: My assumption was that that pond was dug some time in the past as a way to provide fill for roads. That it was never any part of . . . [a] stormwater treatment system. And that it conveyed upstream water through the pond and then on down into Choctawhatchee Bay. It was strictly a [borrow pit and a conveyance pond.] It was never permitted as a treatment system in any way that I was aware of in my diligence [in determining whether the extension should be permitted.] Tr. Vol. II at 79. Once Mr. O’Donnell’s testimony entered the record at the behest of Mr. Chbat, the burden shifted to Mr. Sheehey to prove that the applicant had not provided reasonable assurance of water quality. Mr. Sheehey did not offer evidence of any testing of the discharge. Nor did he offer testimony that rebutted Mr. O’Donnell’s opinion. In fact, the testimony of Mr. Wilkinson (Mr.Sheehey's witness) supported Mr. O'Donnell's opinion with regard to water quality. See Tr. Vol. III at 112. In sum, the Department made assumptions that are found to be reasonable based on Mr. O’Donnell’s expertise and experience. Those assumptions were not shown to be unreasonable by Mr. Sheehey. The Department’s conclusions about water quality flow directly from Mr. O’Donnell’s reasonable assumptions. Reasonable assurances have been provided that the project will not violate water quality standards. Public Interest Test Choctawhatchee Bay is not designated as an “outstanding Florida water.” The test that Mr. Chbat must meet therefore is whether the activity proposed by the permit application is “not contrary to the public interest.” § 373.414, Fla. Stat. In making that determination, the Department is directed by the statute to consider and balance seven criteria. See § 373.414(a) 1-7, Fla. Stat. Of the seven, three are at issue once water quality is determined to be of no concern. Two of the three, “[w]hether the activity will be of a temporary or permanent nature,” Section 373.414(1)(a)5., Florida Statutes, and “[t]he current condition and relative value of functions being performed by areas affected by the proposed activity,” Section 373.414(1)(a)7., Florida Statutes, do not require in-depth consideration. With regard to the nature of the project time-wise, the evidence establishes that the culvert extension is intended to be permanent. With regard to current condition, the area affected by the proposed activity is a residential lot, a substantial portion of which is under water following heavy rain. To facilitate the conveyance of stormwater, the lot is served by the Swale. The Swale is not functioning optimally because of lack of maintenance and because of the Ridge. With regard to relative value from the standpoint of water quality, the function being performed by the lot and the Swale is little, at least as established by this record. While it is certainly true that the lot with or without the Swale will filtrate and otherwise treat stormwater runoff from the pond, the difference in the quality of the stormwater conveyed by the culvert extension from that which would enter the Bay without the extension is not significant. See the discussion above of Mr. O’Donnell’s accepted opinions. Of the seven statutory criteria to be weighed and balanced by the Department, the one that is central to this case is found in subparagraph 1., of subsection (1)(a): “[w]hether the [culvert extension] will adversely affect . . . the property of others.” The “property of others” in this case is the property of Mr. Sheehey. The Project’s Effect on the Property of Mr. Sheehey. For the reasons discussed in paragraphs 63-70, above, Mr. Chbat has failed to provide reasonable assurances that the project will not have a detrimental effect on the property of Mr. Sheehey. The extent of the detrimental effect to Mr. Sheehey's property is difficult to determine from this record but it is highly likely based on all the evidence of record that there will be a detrimental effect: additional flooding in heavy rain events.
Recommendation Based on the foregoing, it is recommended that the Department of Environmental Protection deny17/ the Amended Permit for the failure of Mr. Chbat to provide reasonable assurances that the project will not adversely affect Mr. Sheehey's property.

The Issue The issue is whether Petitioners are entitled to an after-the-fact permit from Respondent for the garage and storage building erected by Petitioners within the floodway of the Suwannee River.
Findings Of Fact Petitioners are the owners of real property located at Lot 15, Suwannee Bluffs as per Plat Book 4, page 18 of the public records of Lafayette County, Florida. Respondent, Suwannee River Water Management District, is an agency of the State of Florida with a responsibility for surface water management within the District. Petitioners live in a home on their Suwannee River property and, in 1999, completed a garage and storage structure on the property without obtaining a permit for construction of the structure. The structure measures 35 feet by 50 feet. It is a concrete block structure on a concrete slab with a metal roof. There are three doors on one side of the structure. The remainder of the structure is enclosed. On or about March 31, 1999, Petitioners, prior to construction of the garage and storage structure, applied for an environmental resource permit for a boat ramp, which permit was subsequently granted. The entire lot of Petitioners is within the floodway of the Suwannee River. The floodway is defined as a work of Respondent's district in Rule 40B-4.3000, Florida Administrative Code. The Suwannee River flows within the boundaries of the Suwannee River Management District. On or about April 18, 2000, Notice of Violation was sent to Petitioners by Respondent. On or about June 19, 2000, Petitioners executed a Notice of Intention to construct a surface water management system for the already completed garage structure. Basically, the surface water management system envisioned by Petitioners would have consisted of modifications to the already completed garage to permit flood waters to flow through the structure. Respondent did not send any responsive formal notice of denial to Petitioners regarding such proposed intention. Instead, Respondent filed a lawsuit in July of 2000, within the 90-day period required by Section 120.60(1), Florida Statutes, in circuit court against Petitioners to prevent the construction of the system. Such action by Respondent constituted denial of Petitioners' requested action. Petitioners' garage construction was in violation of Ordinance 1-87 of Lafayette County, Florida, and in fact, Petitioners received a Notice of Violation from Lafayette County, Florida, dated December 9, 1999, which has still not been resolved. Rule 40B-4.3040, Florida Administrative Code, prohibits the placing of a structure in the works of a District without a works of the District development permit. Petitioners' garage structure was not permitted and was in violation of the rules of the District in force and effect at the time of its construction, notwithstanding Respondent's informal delegation of enforcement of those rules to local county governments in Respondent's district prior to July 1999. Rule 40B-4.3030 Florida Administrative Code, proscribes the issuance of a works of the District's development permit for any work structures, road, or other facilities which have the potential of individually or cumulatively reducing floodway conveyance or increasing water surface elevations above the 100-year flood elevation or increasing soil erosion. Testimony of two experts offered by Respondent at the final hearing establishes that the structure in question will cumulatively reduce floodway conveyance and increase water surface elevations above the 100 year flood elevations and potentially increase soil erosion. Adverse impacts to the public interest include the following: increased flood levels; increased scouring by debris and erosion; and increased water surface elevations above the 100 year flood elevation. The cumulative impact of allowing Petitioners' structure and other structures would magnify the problems of increased erosion, debris damage, and floodway conveyance. The cumulative impact from such construction along the water could have significant cumulative adverse impact on the waters of the State of Florida and specifically, the Suwannee River.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Suwannee River Water Management District enter a Final Order dismissing the petition in this case and denying the issuance of an after-the-fact works of the District permit to Petitioners.

The Issue The issue to be resolved in this proceeding concerns whether the applicant, Craig Watson, has provided reasonable assurances in justification of the grant of an Industrial Waste Water Facility permit for a rotational grazing dairy to be located in Gilchrist County, Florida, in accordance with Section 403.087, Florida Statutes, and the applicable rules and policies of the Department of Environmental Protection. Specifically, it must be determined whether the applicant has provided reasonable assurances that the operation of the industrial waste water facility at issue will comply with the Department's ground water quality standards and minimum criteria embodied in its rules and relevant policy, including draft permit conditions governing the proposed zone of discharge for the project. It must be determined whether the ground water beyond the proposed zone of discharge will be contaminated in excess of relevant state standards and criteria and whether the water quality of the G-II aquifer beneath the site will be degraded. Concomitantly it must be decided whether the applicant has provided reasonable assurances that the proposed project will comply with the Department's effluent guidelines and policy for dairy operations as industrial waste water facilities, pursuant to the Department's policy enacted and implemented pursuant to its rules for granting and implementing industrial waste water facility permits, as they relate to dairy operations.
Findings Of Fact The Respondent Craig Watson has applied for an Industrial Waste Water Facility permit to authorize the construction and operation of an 850-cow, rotational grazing dairy, with accompanying dairy waste management system, to be located in Gilchrist County, Florida. The system would be characterized by ultimate spray application of waste effluent to pastures or "paddocks" located on a portion of the 511-acre farm owned by Mr. Watson. The rotational grazing method of dairy operation is designed to prevent the ground water quality violations frequently associated with traditional dairy operations. Traditional dairy operations are often characterized by intensive livestock use areas, which result in denuding of vegetation and consequent compacting of the soil, which prevents the effective plant root zone uptake method of treating dairy waste and waste water for prevention of ground water quality violations. Such intensive use areas are typically areas around central milking barns, central feeding and watering troughs, and other aspects of such operations which tend to concentrate cows in relatively small areas. The rotational grazing dairy attempts to avoid such problems by dividing a dairy farm's surface area into numerous pastures which cows can graze upon with constant and frequent rotation of cows between such pastures. This avoids overgrazing or denuding of the cover crop upon which cows graze, which is so necessary to proper treatment of wastes through root zone uptake. A rotational grazing dairy is designed to re-cycle cow manure for use as fertilizer to grow and re-grow the forage established on the site in the paddocks or pastures. The rotational grazing method is based on the theory that nutrients from cow manure can be captured in the root zone and uptaken as fertilizer for the plant upon which the cattle graze. The waste from the barn area is collected in a waste storage pond or lagoon and sprayed as liquid effluent on the grassy cover crops established in the various pastures, as is the sludge or more solid waste removed periodically from the waste storage lagoon. The applicant, the 511 acres and the project itself would use approximately 440 acres of that tract. The site is approximately 6 miles south of the Santa Fe River. The majority of the soil on the site consists of fine sand and clay-sand type soils. The dairy would contain approximately 850 cows. Lactating cows (cows being milked) would be grazed in some 36 pastures divided by fencing. They would be grazed in the pastures approximately 85 percent of the time and lactating cows would be in the milk and feed barn located in the center of the lactating cow pastures approximately 15 percent of the time. The manure from the barn, approximately 15 percent of the total animal waste, would be collected and placed in the collection lagoon for spray irrigation on the forage crops grown in the pastures. The remaining 85 percent of the waste would result from direct deposition on the pastures by the cows. The rotational grazing dairy would contain permanent watering troughs in each of the 36 pastures. This creates the possibility of numerous "high intensity areas" or areas characterized by a high level of cattle traffic. This circumstance can result in denuding the cover crop or grasses around such water trough areas which would result in a failure, for that area, of the root-zone-uptake means of waste treatment of nitrates. In order to minimize that eventuality, the cattle would be rotated on a frequent basis from paddock to paddock in an effort to maintain nitrate balance and maintain the sanctity of the cover crop, as would the option of employing movable watering troughs so that areas of denudment of the grass or forage cover can be avoided. Manure would be flushed from the milking and feeding barn with approximately 2,000 to 5,000 gallons of water after each milking and at the end of each shift. Wastewater would then flow into a sand trap or filter and thence through an underground pipeline into an 80 foot x 84 foot concrete-lined storage lagoon. The final site of the storage lagoon has not been firmly determined. The site proposed in the application is located in part over a depression which is a suspected karst feature or area that may be subject to sink hole formation. Therefore, consideration should be given locating the waste lagoon so as to avoid that depression and the permit should be conditioned on installation of the lagoon so as to avoid known karst features. Effluent from the storage lagoon would be applied to 245 acres of pasture with a movable spray gun. The settled sludge from the lagoon would be spread on the same land periodically. The primary grass crop on the site intended for cattle forage would be Coastal Bermuda grass. Coastal Bermuda grows through a large part of the year and is normally dormant, in the climate prevailing in the Gilchrist and Alachua County area, from mid-October until early March. There would thus be little nutrient uptake during that time but to off-set that dormant state rye, wheat, rye grass, sorghum and other small grains could be grown on the site during the winter months in order to continue the waste treatment function of the cover crops. MANAGEMENT PLAN The Department currently does not have in effect a specific rule requiring dairies in north Florida to obtain permits to construct and operate per se, although such a rule does prevail for dairies in the Okeechobee Basin in south Florida. Since 1990, however, the Department has, by policy, required permits for new dairy facilities in the Suwannee River Water Management District as industrial waste water facilities. This policy is derived from the general regulatory authority contained in Section 403.087, Florida Statutes, and Chapter 62-670, Florida Administrative Code.1 The Department policy is described in a letter in evidence from the Department to applicant Watson containing the required conditions on any grant of the permit, to which the applicant has agreed. Those requirements are as follows: Management Plan A site-specific plan, with design calculations, providing for collection, storage and disposal of all wastewater from milking parlor and of runoff from the 25-year 24-hour storm event from all "high intensity" areas within the dairy farm. The calculations should include stormwater computer model SCS TR-55 or similar. Supporting documentation for the plan shall include but not be limited to the following: Water budget and balance, detailed and itemized. Nutrient budget, including wastewater and solids management. Crop management plan with projected crop nutrient uptake rates. Herd management plan, including locations of barns, travel lanes, feed areas, pastures, and management of dry cows and heifers. Treatment and disposal system details, construction details and methods, pumping systems and capacities, irrigation system details, lagoon design and capacity, and site plans. Ground Water Monitoring Plan Determination of ground water depth, variability and direction(s) of flow. Topographic site plan which includes the location of facility property boundaries, sinkholes and cooling ponds. Ground penetrating radar (GPR) if located within Suwannee River Water Management District. Site borings for determination of soil properties, depth and extent of low permeability zones, and confirmation of GPR results. Proposed locations, construction, and development criteria for monitor wells. Inventory of potable wells within 1/2 mile of site. Determination of current ground water quality and compliance. Such plan shall be prepared in accordance with the standards of the USDA NRCS, at a minimum, and shall include detailed instructions for construction, operation, and maintenance of wastewater/runoff collection, storage and disposal systems. DEP Exhibit 1. The various expert and fact witnesses for the Respondents described in their testimony the constituency of that Management Plan and the reasons, within their various scientific discipline areas and their personal factual knowledge concerning why it should be required for the site and project at issue. The 850-cow herd which would be contained on the proposed dairy consists of 550 lactating cows which are milked on a daily basis but also contains 80 dry cows and 220 heifers. Thus some 300 cattle on the dairy will not be milked at any given time and consequently will not contribute to use of the high intensity barn area and the waste collected in the anaerobic lagoon to the extent that those non-milking cattle are not fed and watered in the central barn area. Their waste would more typically be deposited directly on the pastures by those cattle themselves. 10 The project is proposed to provide for on-site containment of all wastes generated by the dairy. There will be no discharge of effluent or other pollutants from the dairy to "waters of the state." The proposed permit requires that no surface water runoff be permitted from the dairy site. The anaerobic or waste collection lagoon is designed to contain all effluent from the milking barn and other high intensity cattle areas in the event of a 25-year, 24-hour storm occurrence. Additionally, a safety factor of one-foot of "free-board" or additional wall height on the anaerobic lagoon is to be provided as an additional safety factor over and above the level expected to be achieved by the above-referenced storm event. The adequacy of the design capacity of the lagoon system is not in dispute. The proposed project and design calls for four monitoring wells to be located along the northern boundary of the property, which is essentially co-extensive with the boundary of the discharge zone at issue. There would be three compliance wells and one background sampling well. The Department's expert geologist, Mr. Davis, was of the belief that an intermediate monitoring well would not be necessary since the four wells would in his view be sufficient to enforce water quality standards. Those wells are located down-gradient according to the known direction of the ground water flow underneath the site, as required by Rule 62-522.600(6), Florida Administrative Code. Although no intermediate wells are provided for by the plan, they have been required at the other two rotational grazing dairies already permitted by the Department in the Suwannee River Water Management Region at least one of which was within a mile of the outstanding Florida water of the Suwannee River. Intermediate monitoring wells at other dairies have shown increased levels of nitrate, although there is no evidence to show that nitrate levels have exceeded state standards at the boundaries of those dairies or their discharge zones. In any event, however, the totality of the expert testimony demonstrates that intermediate wells would provide an efficacious early warning system to predict increases in nitrate contamination. Thus adjustments in the waste and commercial fertilizer nitrate application could be made so that prevention of violation of nitrate standards, by the time waste water migrated to compliance wells around the boundary of the site, could be effected. This would have a substantial predictive value to avoid future nitrate contaminant violations before they occur and they should be installed as a condition on permitting. The proposed dairy design and operation involving rotational grazing is undisputed to be more beneficial to environmental water quality considerations than a traditional cattle confinement type of dairy. The rotational grazing dairy is characterized by cattle spending minimal time in high intensity milking, feeding, and watering areas. Additionally, there will be a significantly lower level of nutrient loading on the pastures with little accumulation of effluent on the land surface. In fact, the deposition of waste through spray irrigation and through the urination and defecation of the cattle directly will still result in a deficit in nitrates needed for adequate plant growth of the grass, and other crop, ground cover necessary for feeding the cattle and making the operation succeed in a waste treatment sense as well. Consequently, it will have to be supplemented by the addition of some commercial fertilizer, the costs of which will result in a natural incentive for the farmer/applicant to ensure that the nutrient loading on the pastures is at a low, environmentally acceptable level in terms of potential contamination of ground water. The proposed dairy has been demonstrated to be consistent with the Natural Resources Conservation Services' requirements and policies concerning dairies and rotational grazing dairies. It is also undisputed that phosphorus is not of an environmental concern with this application and project. There is sufficient iron and aluminum coating on the soils involved so that excess phosphorus will be retained on the site and it is undisputed that nitrogen is the only limiting factor in the design of the dairy. NITROGEN BALANCE The specific concern with regard to the application and the dairy operation is nitrate leaching below the root zone of the crops grown on the surface of the dairy. The dairy is designed to use nitrogen and nitrates by growing crops in the pastures which will then be eaten by the dairy cows, so that the nitrogen is re-cycled with the resulting animal wastes being used as fertilizer for the same grass or crops which the cattle continuously graze. It is anticipated that the amount of nitrogen produced by the dairy cows will be insufficient to optimize that plant growth. Therefore, additional fertilizer will be required to be applied to the land surface in the pastures at times. The additional nitrogen fertilizer will only be applied when testing of soil, and particularly plant tissue analysis, which will be done a regular basis, shows that application of commercial fertilizer is needed to supplement the natural cattle-waste nitrogen. Nitrogen is a concern because if too much of it is applied to the land surface, it may leach below the plant root zone and eventually migrate to ground water. Nitrogen in high concentrations can be potentially harmful to human health, so state drinking water standards have been established for nitrogen with regard to the issuance of industrial waste water permits. The state drinking water standard for nitrate is ten parts per million at the zone of discharge, that is, the zone of discharge into the ground water aquifer. The dairy is designed in such a way that nitrate levels will not exceed water quality standards. The design is determined by reviewing nitrogen balances and making sure that excess nitrogen will not leach past the root zone. The engineers evaluating and designing the project for the applicant, and testifying concerning it, arrived at a "mass balance" to estimate the nitrogen amounts on the site. This mass balancing is required by the Department in the required estimating of the pounds of nitrate leachate. Nitrogen can be removed from the dairy operating system through atmospheric losses or "volatilization" particularly from the urine component of nitrogen application. It can be removed through milk losses, whereby nitrogen is removed from the digestive system of the cattle through its being bound up to some extent in the milk produced by the cattle and sold off the dairy site, as well as some minimal leaching of nitrate through the soil. The nitrogen that is not removed by volatilization to the atmosphere (excluding the small amount re-deposited by rainfall) will be cycled through the cows and the crops along with any supplemental nitrogen applied from time to time in order ensure optimal plant growth. The mass balance, or amount of pounds of nitrate in the leachate, was determined by considering the amount of water flowing through the system. The re-charge rate was established by the applicant's engineer Mr. Holloway to be 17 inches. This means that there will be 17 inches of rainfall leaching below the root zone of the cover crops to reach ground water. The re-charge rate can be determined by computing the average of the evapo-transpiration and average rainfall and subtracting the difference. It can also be calculated by employing computer models such as the "GLEAMS" model. Mr. Holloway, the applicants engineer, used both sources or methods and reached the figure 17 inches. The GLEAMS model is a computer model that uses local data to determine water budgeting and recharge rates. Mr. Holloway also used a 50 percent volatilization rate for the nitrate losses when determining his mass balance. The applicant's experts also considered the plant uptake rates and concluded that the uptake rate would be between 500 and 700 pounds of nitrogen uptaken per year, per acre, by the plant cover. In order to be conservative and to install a sufficient safety factor in the system to avoid overloading it with nitrates and endangering ground water quality, they employed a lower uptake rate in their calculations and recommendations to the applicant, and thus to the Department, as to the amount of nitrogen applied per acre, per year, from all sources to only be 400 pounds. The conditions imposed by the Department in the "free-form" consideration process and draft permit thus limits the total pounds of nitrogen permissibly applied to this site to 400 pounds per acre, per year. Those 400 pounds of nitrogen are represented by 260 pounds applied from manure from the livestock and no more than 140 pounds applied from commercial fertilizers purchased by the farmer, Mr. Watson. The 400 pounds of nitrogen per acre, per year, as a condition on the permit is less than that allowed at the other rotational grazing dairies previously designed by Mr. Holloway and approved. Additionally, Mr. Cordova of the Department established that there are no rotational grazing dairies that have a higher nitrogen deficit than the Watson dairy. This further provides a significant safety factor not present in other approved dairies. Atmospheric losses of nitrogen up to 80 percent have been documented with similar dairy operations. Atmospheric losses can occur through both volatilization and de-nitrification. Volatilization is the process where nitrogen is removed from the system by the ammonia in the waste products, changing into a gaseous state and migrating into the atmosphere as a volatile gas. De-nitrification is the process where microbes, principally in the absence of oxygen (anaerobic) reduce nitrates to nitrogen gas and to possibly N2O, which is a volatile, and then allow it to escape into the atmosphere. The applicant has agreed, as a condition to the permit, to apply soil testing and crop tissue analysis as well as quarterly reviewing of the monitoring wells before he determines to supplement the natural fertilizer deposited from the animals with additional commercially purchased fertilizer. The commercially purchased fertilizer would represent a substantial investment in purchase costs and in labor costs for its application. This is an additional safety factor because the applicant clearly would not have an interest in applying any more fertilizer than was absolutely needed to secure optimum plant growth for grazing purposes and nitrogen uptake or waste treatment purposes. This is a further method which will prevent excessive nitrate nutrients from being deposited on the site and possibly into the ground water. Dr. Bottcher, an expert witness for the applicant, testified that he expected nitrate levels at the zone of discharge within the boundaries and beneath the surface of the dairy farm to be between 4 and 6 parts per million. Mr. Holloway expected within a reasonable degree of certainty that on a long term average, with about 4,000 pounds of nitrate leaching below the root zone system, that the concentration directly below the farm beneath the root zone would be between 2 and 3 parts per million. Indeed, the proposed operation would be similar to the existing condition at the Watson farm involving grazing beef cattle on a system of pastures, with row crop operations. Row crops typically have a higher impact of nitrates than the proposed dairy operation would have and beef cow grazing would have a similar impact, although it would be slightly less. Thus the proposed operation is similar in its nitrate impact to the existing conditions at the site. Moreover, the applicant is limited by the permit conditions already agreed to, to spray manure on the spray field area at the rate of less than one half of an inch. The spraying to that limitation would probably take from two to five hours per week. One of the important safety mechanisms in achieving a nutrient balance on the dairy site and in its operation, so as to ensure that ground water quality violations do not occur, is the application rate of nitrate to the land surface. As shown by Dr. Bottcher's testimony, the farmer may increase crop production by applying more fertilizer during seasons of heavy growth of the plant cover. The application rate can then be decreased when there is less growth and, therefore, less need for nutrients to grow the cover crops. A smaller application rate will increase the volatilization rate by avoidance of the infiltration of the nitrate bearing effluent into the soil through hydraulic action and through the saturation mechanism, since a smaller amount of application would tend to leave more of the effluent within less than one inch of the land surface, or on the land surface, thereby allowing it to be volatilized more readily. This circumstance will decrease the amount of nutrient leaching below the root zone and thus prevent the nitrates from being transmitted to the ground water. A number of crops can be grown successfully and appropriately on the site in order to provide the grazing forage needed for the operation of the dairy. Examples, depending upon the season of the year, are rye, wheat, grain sorghum, and various grasses, including Coastal Bermuda grass. Coastal Bermuda is a perennial grass, high in protein available for livestock and is already established on the site. The various other crops can be grown as well and some that grow in the winter months, such as rye, will be grown by Mr. Watson. The growing of the various cover forage crops are limited by the limitation in the permit which is conditioned on maintaining a cover crop growth situation where the average annual uptake is at least 400 pounds per acre (the evidence reveals that in reality it would be more on the order of 500 to 700 pounds per acre, per year). Dr. Pollman and Dr. Upchurch, expert witnesses for the Petitioners, question the nitrogen balancing and leachate predictions arrived at by the applicant's expert witnesses, as well as those of the Department. Neither Drs. Pollman nor Upchurch had any prior experience or expertise with testing for a nitrogen balancing on rotational grazing dairies. Instead they utilized various models to attempt to predict leachate amounts. Dr. Pollman's modeling utilized formulas prepared by the applicant's experts. His modeling showed a high percentage of the predicted outcomes to be actually within regulatory standards for nitrates, even though all of his estimates failed to take into account the variable inclusion or application rate for nitrogen through commercial fertilizer which will only be applied on an as needed basis after appropriate plant tissue and soil tests show that commercial fertilizer should be applied. Likewise, Dr. Upchurch's modeling results were also mostly within acceptable standards for nitrate concentrations unless one assumes that the nitrogen application rates exceed the amounts allowed under the permit, which will not be the case in reality because obviously the permit limits must be complied with. Dr. Upchurch also utilized a model, "NLEAP," which was neither designed nor calibrated to be used for predictive capabilities and is still considered experimental by the NRCS. WASTE LAGOON The applicant proposes to construct a waste storage lagoon designed to hold seven days' waste water generation capacity or 26,000 gallons per day. In addition to that required storage for a 25-year, 24-hour storm event, an additional safety factor of one foot of free board has been designed into the lagoon system. The lagoon will be constructed with 6 inch thick, fiber-reinforced concrete. No evidence was offered by the Petitioners that the lagoon design itself was faulty or inappropriate, rather the Petitioners contend that there is a chance that a surface failure beneath the lagoon, by the result of a sink hole developing, particularly in the present preliminary location proposed for the lagoon, could cause the lagoon to crack. The applicant will, however, in order to ensure that the area is suitable for the lagoon have the appropriate engineer "over-excavate" the site in order to minimize the change of a sink hole developing. Additionally, soil borings will be done beneath the surface to provide additional assurance that the lagoon will not fail due to voids or sink holes being present beneath it. Because the lagoon is presently preliminarily located in an area that appears to embody an old, inactive karst depression, consideration should be given to altering the site of the lagoon slightly so as to avoid this area, after soil borings and other investigation is done to ascertain whether the area poses a risk of lagoon failure. Additionally it must be pointed out that because the applicant would need to expend a substantial investment to rebuild the lagoon in the event of such a failure, he has a strong incentive to locate the most suitable geological placement for the lagoon in any event. GEOLOGIC SITE CHARACTERISTICS It is undisputed that the geology underlying the surface of the dairy site is karst in nature: that is, it is characterized by a sub-strate of limestone which can, through the dissolution process caused by percolating water, be susceptible to fissures, voids, underground conduits and sink holes. This, however, is true for essentially all areas used for agriculture in the Suwannee River Area Water Management District, the area to which the subject above- referenced policy concerning installation and permitting of dairies applies. Because of the karst nature of the area, sink holes and other potential surface openings to the ground water could occur at the site. It is most significant, however, that both Mr. Holloway's and Dr. Kwader's testimony established that the soil layer at the site was more than sufficient to protect the ground water. In fact, the soil layer averages from 45 to 50-feet thick over the underlying limestone sub-strate of the Ocala Formation. Further, the proposed permit and its conditions would require a management plan which, with the conditions already placed on the permit and recommended herein, will adequately deal with the possibility of sink holes, "pipes" or "chimneys" developing on the site. The dairy design success is derived essentially from the sufficient nutrient uptake in the root zone of the plant cover, balanced with careful control of the application rates of both the natural fertilizer from the cows and the commercial fertilizer which will supplement it from time to time. Any possibility that the treatment zone for nitrates associated with the plant root zone would be by-passed by the effluent as a result of sink holes or other types of fissures developing can be resolved by proper management practices, which the conditions proposed for the permit and those recommended herein will insure are implemented. For instance, if sink holes, other depressions or holes develop in the site, they will be filled with soil to a depth of five feet, with an impervious clay cap on top of that and then a layer of top soil to allow for re-establishment of the root zone on the surface. The permit should be so conditioned. Moreover, if sink holes or other voids develop that are too large to be so filled and pose a risk of migration of effluent below the root zone to rapidly to the ground water, they will be fenced off and cows will not be allowed in the area. The area will be removed from the irrigation application process until repairs are made, under the presently proposed conditions on the permit. An additional condition should be imposed whereby any sink holes or other voids or similar breaks in the ground surface which pose a risk of effluent rapidly migrating to ground water should be bermed around the circumference to prevent effluent or stormwater laden with nitrates from the land surface from entering the fault or cavity. The applicant is required under the proposed conditions on the permit to report to DEP any sink holes which develop within a certain period of time in the barn area. Cows are not to be permitted to enter into any of the sink hole areas by additional fencing, if necessary. If sink holes develop in the spray field there can be no discharges of fertilizer or irrigation on those areas until the sink holes have been repaired in the manner referenced above. The phosphate pits on the site will also be fenced to prevent discharges past the root zone potentially caused by cattle entering the pits. Additionally, berms are required to be constructed around the phosphate pits to prevent surface water from storm events or other means by which nitrates from the ground surface can be transported into the pits and then possibly to ground water. Any holes which may develop, also called "piping failures," around the periphery of the phosphate pits should be treated in a similar manner to prevent the migration of surface water into those holes whether or not they communicate with the phosphate pits themselves by fencing and berming. These arrangements coupled with the fact that the phosphate pits are characterized by a sufficient soil layer in the bottom of the pits between the bottom surface of the pits and the water table or aquifer will constitute reasonable assurance that the pits will not result in a conduit or path for nitrate-laden, surface water to migrate past the root zone directly into the ground water aquifer. Mr. Holloway, an engineer, testifying for the applicant conducted soil borings on the site to verify the Natural Resources Conservation Service (NRCS) surveys as accurate and to ensure that an adequate root zone for treatment purposes existed. Additionally, the NRCS did a ground penetrating radar survey or study on the property. The Petitioners also did a separate ground penetrating radar study performed by Mr. Windschauer. The Petitioners study identified a number of karst-type "anomalies" on the property. The number of anomalies located by Windschauer was not unusual for a such a karst geologic area, but, in any event, all of them had adequate soil depth to support the crops necessary to establish the root zone and maintain the nitrogen balancing. Soil borings were conducted, as well on four of the anomalies, under Dr. Upchurch's supervision. They confirmed that there was adequate soil depth to support crops and protect groundwater. The conditions already imposed on the permit to which the applicant has agreed, require a minimum of five feet of soil depth to ensure adequate treatment including the soil below the root zone and that soil depth and plant cover will have to be maintained even if repairs are necessary to karst anomalies or "sink holes," or the dairy will have to cease operation. The soil depth on the dairy is approximately 45-50 feet and the water table is approximately 55 feet below the ground surface. While the Department's expert, Mr. Davis, is satisfied that the location of the monitoring wells and the number of wells are adequate to monitor compliance with water quality standards for groundwater at the site, the draft permit conditions allow for a change in the number and the location of the monitoring wells. The evidence in the case, including that which shows that an intermediate well at another similar dairy site has shown elevated nitrate levels (although it has not been shown that other conditions are similar to those proposed in this permit application and in the evidence) would indicate that it would be prudent to install intermediate monitoring wells, upgradient, within the dairy site to serve as an early warning, predictive mechanism to avoid water quality violations at the boundary of the zone of discharge. This will allow time for steps to be taken, through various adjustments in the operation, to prevent any violations of the ten parts per million nitrate groundwater standard. The permit is recommended to be so conditioned. Dr. Kwader performed a photolinear trace analysis. He indicated that he did not find any particular linear features such as fractures. A fracture in the limestone stratum is significant in that it can provide a conduit or preferential pathway through the sub-surface rock and thus transfer contaminants from one point to another at a more rapid rate than simple percolation through soil and pores in the rocks. This could result in excessive nitrates being deposited in the groundwater aquifer before an adequate treatment time and mechanism has had its effect on the nitrates. A fracture or conduit flow will, however, cause dilution and Mr. Davis, for the Department, testified that he did not expect a higher concentration of nutrients in a fracture than in the surrounding rock. Additionally, there will be substantial dilution once the nutrients reach the aquifer and begin moving laterally. The dilution will be proportional to the water moving through the conduit, meaning that if the fracture is relatively large, then the concentration of nutrients will be proportionately smaller because of the higher volume of water. Such linear features or fractures are difficult to observe through 50 or more feet of soil existing at the site above the rock stratum and the top surface of the aquifer. Dr. Upchurch, for the Petitioners, also performed a photolinear trace analysis and identified two areas as being highly probable, in his belief, for linear fracture features beneath the farm and surrounding area. He believes there is a possibility of a number of other fractures beneath the Watson property, although the evidence does not definitely identify such nor the measures or precise locations of any such postulated fractures. The Watson property, however, is not unlike any of the surrounding karst terrain with respect to such potential linear fracture features and, in fact, much of north Florida can be so characterized. Moreover, Dr. Upchurch himself agreed that only a limited area of the Watson farm would be impacted by such features, and further, if they are present, they will not impact the nutrient balance aspect of the dairy design because it will perform above many feet of soils separating it from the fractures, if they exist. Limestone pinnacles protruding to the land surface can provide preferential pathways for water to migrate downward to the groundwater aquifer in a manner similar to that posed by a sink hole. They can also function as a break in the soil and plant root zone covering the spray effluent treatment area if allowed to remain exposed. Limestone was observed within one of the mine pits and in a sink hole. It is not clear whether it is a pinnacle which leads down to the sub-strate containing the aquifer or is merely a remnant boulder. In any event, these pinnacles or limestone outcroppings or boulders, whatever they prove to be, will not result in a preferential pathway for water to migrate to the aquifer because the management plan conditioning the permit requires that any limestone protruding to the surface be sheared off and replaced with top soil and vegetation. The permit conditions require that at least five feet of soil overlaid by vegetation must be present for all areas in the spray field. No exposed groundwater was observed in any of the sink holes. In fact the aquifer water level would be at least ten to twenty feet below the bottom of any pit or sink hole observed on the property. An additional 50-foot buffer from the property boundary surrounds all of the paddocks, providing an additional safety factor before the outside boundary of the zone of discharge is reached. The proposed dairy is located approximately six miles south of the Sante Fe River at its nearest point. The Sante Fe River is an outstanding Florida waterway in accordance with Rule 62-302.700(9)(i)27, Florida Administrative Code. The dairy site is not within the flood plain of the river and there will be no surface water discharged from the dairy, including none to the Sante Fe River. Any impact the dairy might have on a water quality in the Sante Fe River would come from groundwater flowing from the site to river. Groundwater beneath the dairy site flows first in a northeasterly direction thence apparently swinging more northerly in the direction of the river, more or less in a "banana shape" flow pattern and direction. Current permitting requirements for such a dairy require that the groundwater leaving or flowing from the zone of discharge must meet "drinking water standards." Those standards are codified in Rules 62-520.400 and 62-522.400, Florida Administrative Code. Those standards require that nitrates not exceed the standard or level of ten parts per million. Dr. Bottcher's expert opinion, which is accepted, is that the dairy design and operation will provide adequate protection to the Sante Fe River with that perameter in mind. He also established that reasonable assurances exist that the river will be adequately protected and not significantly be degraded alone or in combination with other stationary installations in addition to the dairy in question. The dairy waste management system has been established by preponderant evidence to abate and prevent pollution of the groundwater to the extent required by the applicable statutes, rules and policies, in that water or pollution will not be discharged from the dairy in violation of the above-referenced standard. Especially because of the great thickness of soil cover and because of the conditions and protective measures designed into the draft permit, and the project and recommended as conditions herein, in order to prevent effluent from bypassing the root zone treatment area due to karst features the preponderant, credible geological and hydro- geological evidence, including that of Mr. Davis, shows, within a reasonable degree of professional certainty, that there are not conditions concerning the hydro-geology or geology in the area of the site as to make it unsuitable for the proposed dairy operation in the manner conditioned and recommended herein. SECTION 120.57(1)(E) - FINDINGS The specific permitting requirements for the rotational grazing dairy at issue are embodied in a policy followed by the Department as far back as 1990. Those requirements are not contained in a Department rule. Rather, the policy is presumably enacted pursuant to the statute referenced by the parties, including the Department, in this case as the general pollution abatement statute, Section 403.087, Florida Statutes. The action of the Department in announcing its intent to grant the permit may be deemed an agency action "that determines the substantial interest of a party and that it is based on an un-adopted rule . . ." to the extent that one might deem this policy, consistently followed in a substantial area of the state since 1990, an un-adopted rule for purposes of Section 120.57(e)(1), Florida Statutes. In that context, the agency must demonstrate that the un-adopted rule comports with the statutory definitional of characteristics of a valid rule. Thus the agency must present proof that its un-adopted rule or "policy" would be valid as a rule. In that context the evidence adduced by the Department and indeed by both Respondents, since they presented a joint case, shows that the policy at issue is within the powers, functions and duties delegated by the legislature in Section 403.087,Florida Statutes, which is a generalized grant of authority designed to give the Department the power to regulate in a way to abate the pollution of waters of the state, including groundwater. It has also been adequately shown that the policy or un- adopted rule does not enlarge, modify or contravene the specific provisions of that law being implemented but rather provides sufficient regulatory details so that the general principals, stated in that statute, can be carried out in terms of the installation, regulation and operation of the subject dairy project. It has been adequately proven that the rule is not vague and that it establishes adequate standards for agency decisions on whether or not to permit such a rotational grazing dairy. It does not vest unbridled discretion in the agency nor constitute an arbitrary or capricious act or policy imposition, because the standards and requirements advanced by the Department as being necessary under this policy or un-adopted rule, for a permit to be granted, must, of legal and factual necessity, be predicated on competent, scientific expert and factual evidence. That has been shown, which likewise meets the requirement that the un-adopted rule be supported by competent and substantial evidence. Likewise, the evidence shows that under the circumstances, given the great public necessity in protection of the groundwater and the Floridian aquifer, that the requirements placed upon a grant of a permit for this project and the conditions placed upon its construction and operation do not impose, under the circumstances, excessive regulatory costs on the regulated person, Mr. Watson, or the governmental entity where the project is located, in other words, Gilchrist County.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is RECOMMENDED: That a Final Order be entered granting the permit requested by Craig Watson to construct and operate the proposed dairy waste management system in accordance with the draft permit proposed by the Department, including the general and specific conditions attached and incorporated therein and also including the general and specific conditions recommended to be adopted and implemented for the proposed system in this Recommended Order, based upon the preponderant, persuasive, credible evidence. DONE AND ENTERED this 23rd day of February, 1999, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 23rd day of February, 1999.
The Issue The issue for consideration in this proceeding concerns whether the Petitioner is entitled to a variance for installation of an on-site sewage disposal system ("OSDS") for property located near the Suwannee River in Dixie County, Florida, in accordance with the provisions of Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner is the owner of certain real property located in Dixie County, Florida, more particularly described as Lot 4, Wonderland Subdivision. The property is approximately 60 by 150 feet in size and was purchased in 1982 for a price of $9,000.00. It is presently appraised at $11,000.00; however, if an OSDS could be permitted and installed, the property would appraise for approximately $22,000.00. The lot was platted in 1957. On October 19, 1989, the Petitioner made an application for a variance from the OSDS permit requirements for the property. The application form indicated, and the Petitioner intends, that this would be a new system for a single-family residence. The residence would contain two bedrooms and would produce approximately 250 gallons per day of sewage flow. The Petitioner desires to construct a residence on the property to have a pleasant place to live and is suffering a hardship because of the investment which he has made in the property, which is of no use to him if he cannot obtain the subject permit or variance and install the OSDS so that he can construct his residence. Alternatively, he is unable to sell the property readily without the ability to obtain an OSDS permit or variance for the property. At the behest of the Respondent in the permit application or variance application process, the Petitioner obtained a survey of the property by a registered land surveyor (see Petitioner's Exhibit No. 2 in evidence). That survey resulted in a benchmark elevation being established of 12 feet above mean sea level ("MSL"). The site of the proposed OSDS installation is 11.71 feet above MSL. The ten-year flood plain elevation for this property is 16 feet above MSL, as verified by records of the Suwannee River Water Management District in evidence without objection. The property is also located within the regulatory floodway of the Suwannee River. Although the Petitioner acknowledged in a general way that he would be amenable to consideration of various alternative types of systems involving piping of sewage effluent to an appropriate upland disposal and treatment area, the use of chemical toilets or other appropriate non-discharge types of treatment and disposal systems, no concrete evidence was adduced from the Petitioner to establish that such are or are not reasonable alternatives to the conventional subterranean septic tank and drainfield type of disposal system with which the variance application is concerned. Consequently, the Petitioner's proof does not establish that no reasonable alternatives exist in order to secure the grant of a variance nor did the Petitioner's proof establish that the type of system proposed would not pollute the ground or surface waters or pose a threat to public health in terms of the standard subterranean OSDS or any alternative systems which the Petitioner might theoretically employ, including the types mentioned above. The Petitioner's proof simply did not establish that installation of a standard subterranean OSDS would only pose a minor deviation from the permitting statute and rules cited herein nor did the Petitioner establish that no reasonable alternatives exist to the establishment of a standard OSDS, as that relates to the substantiality of the hardship which the Petitioner is experiencing in not getting the OSDS originally requested permitted; and the Petitioner did not establish that any system proposed would not pose a threat to public health or pollute ground or surface waters. In summary, the Petitioner did not establish that a sufficient hardship is experienced, because reasonable alternatives have not adequately been explored and considered by the Petitioner nor made a part of the subject of Petitioner's proof nor has the Petitioner established that a grant of a variance would involve only a minor deviation from the permitting statute and rules standards because it has not been proven that the public health nor the ground or surface waters would not be adversely affected. Finally, because the property is located in the regulatory floodway of the Suwannee River, under Rule 10D- 6.047(6), Florida Administrative Code, before a mounded or filled OSDS could be permitted and installed, which is one alternative under consideration, a registered professional engineer must certify that the mounding of the system and installation of fill in the regulatory floodway area would not cause elevation of the "base flood" of the Suwannee River. No such engineering evidence or testimony has been adduced iii this proceeding; therefore, such an alternative system cannot herein be recommended for approval.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying the Petitioner's application for a variance from the statutory and regulatory requirements for an OSDS permit.

The Issue The issue in this case is whether the development order issued by Polk County for Robert Crowder's development known as Paradise Country Estates complies with Chapter 380, Fla. Stat. (1991). The Department of Community Affairs' Petition for Appeal of Development Order (the DCA Petition) alleges that the development order is contrary to Polk County's 1985 comprehensive plan for the following reasons: Paragraph 11 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 9, Objective III, "Natural Resources," of the Land Use Element (LUE) of the 1985 Plan. Policy 9 states: "Structures should be placed in a manner which will not adversely affect the natural flow regime and which will not reduce the recharge capabilities." Paragraph 12 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 10, Objective III, "Natural Resources," of the LUE. Policy 10 states: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Paragraph 13 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 11, Objective III, "Natural Resources," of the LUE and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Respectively, these policies state: 11. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Paragraph 14 of the DCA Petition alleges that the development order is contrary to a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources," which describes the Green Swamp as a "rare and unique land area resource for conservation consideration" and also states: The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Paragraph 15 of the DCA Petition alleges that the development order is contrary to the following section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships": The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. Paragraph 16 of the DCA Petition alleges that the development order is contrary to Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan: "Protect or improve existing ground and surface-water quality." Paragraph 17 of the DCA Petition alleges that the development order is contrary to Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE: Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. Paragraph 19 1/ of the DCA Petition alleges that the development order is contrary to Policy 2, Objective IV, "Residential Uses," in Part V of the LUE: Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. Paragraph 20 of the DCA Petition alleges that the development order is contrary to Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code). 2/ Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Paragraph 21 of the DCA Petition alleges that the development order is contrary to Section 5-2(4) of Polk County Ordinance 81-28. 3/ Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Paragraph 22 of the DCA Petition alleges that the development order is contrary to Section 6-2(3)(a) of Polk County Ordinance 81-28. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site.
Findings Of Fact The Proposed Project and Location. The project site is on Dean Still Road in Polk County, approximately 2 miles west of State Road 33. It is approximately 6 and 1/2 miles from Polk City and 15 miles from the City of Lakeland. The proposed project is comprised of 356 lots on approximately 1280 acres with a gross density of 1 unit per 3.6 acres. Although the average lot size varies, the project was reviewed under the Southwest Florida Water Management District's (SWFWMD) criteria for rural development which requires that at least 90% of the lots be at least 2 acres in size (excluding jurisdictional wetlands), and 10% of the lots be at least 1 acre (excluding jurisdictional wetlands). The site has been zoned Rural Conservation under Polk County's Zoning Code for approximately 12 years. This designation allows a density up to 1 unit per acre. Individual water wells and on-site waste disposal systems (septic tanks) will be utilized for each home. There are no water or sewer extensions proposed for the site or for adjacent areas by any governmental entity. Access to the site from Polk City is along Dean Still Road, which is unpaved at this time. The County has plans to pave it in the near future. Of the 1280 acres comprising the project site, 362 acres have been claimed as jurisdictional wetlands and approximately 642 acres have been mapped within the 100-year floodplain by the Federal Emergency Management Agency (FEMA). 51 of the lots platted in the project are entirely within the FEMA 100- year flood plain. Several other lots contain large portions within FEMA 100- year flood plain. Despite the significant amount of wetlands and floodplains on the site, the project is designed so that no net loss will occur in the floodplains and less than 1% (.59%) of the jurisdictional wetlands will be impacted by development. Impervious conditions on the site will only increase by 2.8% after development. All structures will be set at or above the 100 year flood elevation, as calculated by the project engineers, and will be constructed in accordance with the County's flood protection standards. The project is designed so that post-development runoff is less than pre-development runoff and post-development drainage basins conform to pre-development drainage basins. Existing drainage patterns for the site are designed to be maintained. The property comprising the project has been used through the years for a variety agricultural purposes, including harvesting watermelons, soybeans, corn, and silage. It has been drained and ditched to facilitate these activities. It is currently being used for grazing cattle. A sod farm is located to the south of the property. Additional cattle grazing lands run south from there to Polk City. To the north of the site are ranchlands which run to the border of the Withlacoochee Wildlife Area. Immediately to the west of the site are 20-30 scattered mobile homes and additional ranchlands in a subdivision known as Evans Acres. This subdivision was initially approved by DCA in 1983, and was comprised of 48 lots on approximately 1,290 acres. The original lots ranged in size from 5 to 60 acres. Apparently, individuals have since split their lots and many of the existing lots are 2 to 5 acres in size. A few of the original lots are used for both residential and ranching purposes. Including the large and small lots, there are approximately 163 lots on the property comprising Evans Acres. On the property directly to the east of the site are approximately 16 mobile homes along Melody Lane. These existing homesite numbers are small and scattered when compared to the 356 lots proposed for Paradise Country Estates. Approximately 120 families live in the general vicinity of the proposed project. The Green Swamp. The project is within the Green Swamp Area of Critical State Concern (ACSC). The site is within the drainage basin of the Withlacoochee River, which has been designated an Outstanding Florida Water (OFW) and is approximately three and a half miles to the north. The Green Swamp ACSC was designated by the Legislature. Chapter 79- 73, 380.0551, Florida Statutes (1991). It was the second area to be designated and now is one of only four areas in the State retaining this designation. The Green Swamp was designated because the area's natural resources were considered to be of regional and statewide importance and because of concerns that uncoordinated development could endanger these resources. The Green Swamp is a regionally significant area for recharge of the Floridan Aquifer. The Green Swamp is unique because the top of the Floridan Aquifer is at or near the surface over much of the area. This creates what is known as the potentiometric high of the Floridan Aquifer. The potentiometric high pressurizes the Floridan Aquifer, permitting it to be used for drinking water wells. The Florida Aquifer serves as the principal source of drinking water for central Florida. It supplies the entire State with about 48 percent of its ground water supply. The potentiometric high also serves to hold back salt water intrusion into the Floridan. Recharge is important in maintaining the potentiometric high of the Floridan Aquifer. Although the Green Swamp has been characterized as a recharge area for the Floridan Aquifer, the actual recharge capabilities of the Green Swamp vary considerably throughout the region. Some areas within the Green Swamp, such as the high, dry, sandy ridge on the eastern boundary of the Green Swamp clearly are high recharge areas. In some areas, the Floridan Aquifer rises essentially to the ground surface, with no confining layer above it. In those areas, a considerable amount of surface water filters into the Floridan Aquifer. In other areas, including in the vicinity of the project site, recharge capability is considerably less. See "G. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code, (3) Ground Water Recharge." The head waters of several rivers, including the Withlacoochee River, are in the Green Swamp. Polk County's Comprehensive Plan. Polk County's Comprehensive Plan, as amended by Polk County Ordinance 85-08 (Ordinance 85-08), is referred to as Polk County's 1985 comprehensive plan, or the 1985 plan. It includes a Land Use Element (LUE) and a Conservation Element. The Land Use Element. The 1985 Plan is a "policy plan." As a "policy plan," the LUE does not map land use classifications or densities or intensities of development. The different parts of the plan must be considered together to ascertain their meaning. As stated in the Foreward to the LUE: The Policy Plan is a flexible and realistic guide to future public decisions. Existing conditions are first determined and analyzed. Then, community goals are identified providing a process of finding out where we are and where we want to go. * * * . . .. The challenge is to determine the means of achieving the identified community goals at minimal cost and the least possible hardship on any segment of our society. Under the policies planning process this is accomplished by developing all possible alternative courses of action that will advance the community toward the desire goal. The policies are then a general statement of purpose and outlining broad principles toward which the plan is guided in the implementation stage. A policy plan does not detail specific actions or locations on a map. Rather it provides a broad framework within which day-to-day decisions are made in a consistent manner toward an identified goal. The ultimate product of those community goals will be the heritage of Polk County's future. At 4-2, the LUE discusses the need to give attention to "the proper distribution of population densities in keeping with sound planning practices, the physical capabilities of the land, and the relationship of the population and housing densities to existing or proposed transportation facilities and other community services." It then speaks to "Retention of Open Spaces": A second potential problem to be faced, as urban growth continues, is the potential loss of the open space characteristics that now contribute substantially to its desirability as a community in which to live and visit. To a large extent, the desirable characteristics are provided by extensive agricultural areas. Such uses are compatible with residential and other types of urban land uses and should be encouraged to remain to the maximum extent possible. Desirable open space is also presently provided by . . . wetland areas not suited for urban development. By encouraging such areas to remain in their present condition, a substantial amount of open space can be retained to provide the needed visual relief and openness necessary within a highly urbanized community. At 4-5, discussing "Retention of Unique Agricultural Lands," the LUE states that cattle raising and field crops are subject to potential intrusion by urban development and states: "The development of planning techniques, which will encourage the retention of important agricultural lands and provide for orderly urban development, thus becomes a matter of considerable importance." The Goals, Objectives, and Policies (GOPs) of the LUE starting at 5-1 include the following: General Goal: To maintain productive and mutually compatible use of lands and waters within Polk County in a manner consistent with the economic, physical and social needs, capabilities, and desires of Polk County and its citizens. Objective I - Agricultural Uses: To ensure that a sufficient quantity of appropriate lands are available and protected for productive agricultural uses necessary to a sound economic base. Policies: * * * 2. Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. * * * 5. Provide all possible incentives for the retention of lands into agricultural production. * * * Objective III - Natural Resources Minimize adverse impacts of development on valuable natural resources including the protection of water quality and quantity in surface and ground waters. Policies: * * * 2. The subdivision and platting of land shall be permitted in accordance with the zoning district applied to the property and in compliance with the Polk County Subdivision Regulations and Flood Protection/Surface Water Management Ordinance. * * * Site alteration should be permitted only when such alteration will not adversely affect the natural flow regime or the natural recharge capabilities of the site. Site alteration should be permitted only when such alteration will not result in the siltation of wetlands or reduce the natural retention and filtering capabilities of wetlands. Site alteration activities should provide for water retention and settling facilities; should maintain an overall site runoff equivalent to the natural flow regime prior to alteration and should maintain a runoff rate which does not cause erosion. * * * Storm water runoff should be released into the wetlands in a manner approximating the natural flow regime. Structures should be placed in a manner which will not adversely affect the natural flow regime and which well not reduce the recharge capabilities. Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. Objective IV - Residential Areas To ensure that an adequate supply of appropriately located lands are available for the development and maintenance of residential areas that can be efficiently and effectively provided with necessary public facilities and services. Policies: Promote and encourage the provision of a wide range of housing opportunities, in appropriate locations, to permit a choice of housing types to suit the particular needs of all citizens. Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. * * * Encourage new residential development that can be effectively served by the existing transportation facilities. Promote new residential development in non-urban areas, that is properly designed to combine with future adjacent development, to create a neighborhood of sufficient size to facilitate the efficient and effective provision of all necessary public facilities and services. Part VI of the LUE, entitled "Alternate Approaches," discusses the pros and cons of different concepts for planning and managing of growth. It settles on a "Resource-Responsive Concept" as the preferred growth alternative. This concept holds in part: Wherever possible, future growth should be encouraged to take place in or near established urbanized areas. Scattered growth incapable of functioning as meaningful self-contained communities should be discouraged. And it is preferable that the urbanizing area, as it extends over extensive areas within the County, not be developed in one continuous, monotonous maze of residential, commercial, and industrial uses - but that there be open space provided at appropriate intervals so as to provide visual relief and a sense of scale to the overall urban community. Such open space areas can be productively utilized for agricultural and conservation purposes or recreation areas, public facilities and services required. It is proposed that the most appropriate urban growth concept to meet such guide-lines and the policy statements of this land use plan be a resource-responsive growth concept. Under this concept, urban growth and development will be guided and encouraged with respect to its responsiveness to the natural and human resource capabilities of the County. Within any given area of the County, the resources will be careful evaluated in terms of their capability to support growth, and the physical form and intensity of development will be then shaped to provide the physical form and intensity of development will be then shaped to provide a balance with such resources. Prime resources to be considered are as follows: Natural Resources Topography and soil conditions Vegetation and tree cover Wildlife habitats present Drainage characteristics; relationship to rivers and lakes Natural water supply capabilities General aesthetic qualities Human Resources Transportation facilities (roads, railroads, airports) Available water supply and sewage facilities Community facilities, such as schools, parks, libraries Protective services, such as fire and police Established land uses within the area Economic conditions and potentials. Part VII of the LUE, entitled "Implementation," states: "Initial implementation of a Comprehensive Plan and initiation of the continuing planning process for growth management requires the establishment of principals and standards for measurement of proposed activities against the adopted policies of the community." It includes a section entitled "Principles and Standards for the Control and Distribution of Population Densities and Structural/Development Intensity," which provides in part: All Types of Urban Development: * * * Each new development or land use should follow sound land planning principles to maximize site advantages, avoiding when possible, adverse impacts on the natural resources and hazards to health, safety, or general welfare. * * * Residential Development: Low-density single-family development (1-4 units/acre), other than rural residences related to agricultural operations, shall be located in areas capable of being developed into stable, cohesive neighborhoods. In a section entitled "Legal Requirements of Implementation," it states that "all actions taken by local government, whether in the form of permitting private development to occur or in the provision of public facilities and services, are required to be fully consistent with the adopted Comprehensive Plan. The plan, once adopted, must occupy a central position in the consideration of all proposed development." In another section, entitled "Coordination with Other Plan Elements," it states that the "land use element cannot be implemented alone [but] must be coordinated with the [other elements]." In another section, entitled "Needed Improvements in the Zoning Ordinance," it is recognized that "it will be essential that a thorough review of the zoning ordinance be undertaken and that the ordinance be revised as appropriate to achieve consistency with overall planning objectives." It acknowledges that there were "major identified deficiencies in the current zoning regulations" and advises that "the following needs among others should be addressed as a minimum in making revisions to the zoning ordinance": "Revision of the Density Requirement in Residential Districts." Despite the admonitions in the 1985 Plan, to date there has been no revision of the land use classifications, densities, or intensities in the County's zoning code. As before the 1985 Plan was adopted, zoning in the Green Swamp ACSC remains Rural Conservation (RC) and allows up to one unit per acre residential development. The Conservation Element. Part II of the Conservation Element of the Polk County Comprehensive Plan is a "Summary of Natural Resources." At 2-18, there appears a section entitled "Rare and Unique Natural Resources," which describes the Green Swamp, as well as other natural resources in the County, as a "rare and unique land area resource for conservation consideration." At 2-19, as amended by Ordinance 85-08, this element of the comprehensive plan also states: This area comprises the hydrologic heartland of Central Florida and contains the headwaters of the Withlacoochee, Hillsborough, Peace and Oklawaha Rivers. The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Part IV of the Conservation Element is a "Summary of Special Problems, Areas, Issues, and Relationships." Starting at 4-2, it addresses the following: Displacement . . .. Cities in Polk County have historically developed on the ridges and the urbanized areas are spreading outward rapidly into the prime citrus lands and the "marginal" (flood prone) lands. There is considerable concern about urban development in wetland soils and flood prone areas. The double barreled concern for development in wetland soils and wetland areas is that they might well serve valuable natural functions and the private and public problems created by development subjected to flood damages. This property damage promotes public pressure for drainage in wet areas. The issue in wetland drainage and flood control is the jeopardy of natural functions that wetlands and water fluctuations provide in natural systems and flood damage costs. . . . [C]oncern for the growing demand for uplands development which steadily displaces [good pasture land] . . . relate[s] to the use of good pasture land for development. Density The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. * * * Water * * * Another area of concern relates to the draw down and recha[r]ge of the Floridan Aquifer and is claimed to be a rational concern of an area much larger than Polk County. * * * Pollution Environmental pollution, as it relates to water, is a major local concern. * * * Water pollution is concerned because of its effects on recreation and tourism. Water degradation and the pollution of lakes and rivers tends to remove the intangible value that Polk County enjoys in thee form of its surface water resources. * * * Also, the related cost issues of municipal sewage treatment and disposal, effluent disposal techniques, septic tank useage are environmentally economic choices to be made by the public. Discussing the topic, "Preservation and Management," starting at 4-4, Part IV of the Conservation Element states in part: Many issues relate to what, how, or when something should be conserved. * * * Lakes, rivers and canals of the county are of concern as sources of flooding and as resources for flood control, if properly managed. Flood prone areas surrounding surface water have been identified for much of the county. These water bodies are also legitimate concerns as the habitat for fish and other wildlife that provide a significant value in their own right. The area of these water bodies are also special scenic and recreational values that contribute to tourism and development. Part V of the Conservation Element is where the "Goals, Objectives and Policies" are found. It start with some general observations, including in part: . . .. It can be expected, therefore, that the natural environment of the county will continue to undergo modification of one type or another in response to the needs of people. . . . The inventory of total space will, therefore, diminish as these changes take place, resulting in corresponding losses within particular categories of natural resources. What is important is that no critical loss of impairment of a natural resource take place; that development be managed so as to create minimum disturbance of the remaining natural resource systems; and that there be compensation replenishments of resources wherever possible. It then lists a General Goal and several resource-specific objectives and policies: General Goal: Maintain, protect, develop and utilized the natural resources in a manner that will balance and replenish the natural ecological systems and will best serve and promote the desired quality of life for Polk County resident, present and future. * * * Water Resource Objective: To conserve and protect the quality and quantity of water resources through proper management. * * * 6. Identify and protect significant acquifer [sic] recharge areas for maximum recharge capability and protect the water available for aquifer recharge. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Protect the functions of the Potentiometric High of the Floridan Aquifer. Prevent further salt-water intrusion into the Floridan Aquifer. Protect or improve existing ground and surface-water quality. Protect the water retention and biological-filtering capabilities of wetlands. Protect the natural flow regime of drainage basins. Rare and Unique Natural Resource Objective: To conserve and protect, through proper resources management, areas having unique natural characteristics and particularly sensitive environmental balance. * * * Policies: Identify all significant areas in Polk County deemed to have unique natural resource characteristics. Encourage proper management of unique wetland areas of the County as a vital water resource. Encourage a proper system for control of development in flood prone and wetland areas to regulate alternation [sic] of the natural system of water retention and storage during periods of heavy rainfall. Preserve and protect, to the maximum extent possible, all delineated areas having valuable unique resource characteristics. Part V of the Conservation Element concludes with a "Summary," which states in part: The objectives and policies set forth above should not be considered as controls to be rigidly applied in every instance of decision-making dealing with the natural environment. Rather, in dealing with resource conservation issues, guidance is preferable to control. . . . A number of potential implementation actions and programs, presented in the following part, will further assist in establishing the direction and scope of conservation activities in the County. Part VI of the Conservation Element is entitled "Implementation." While acknowledging at 6-1 that Polk County cannot establish an implementation program unilaterally, without regard to the co-responsibilities of other governmental authorities at the regional state and federal levels, it states at 6-2 that Polk County "can and should": Utilize the general objectives and policies established by this Element as considerations in all decision making concerning the use and improvement of land within the County. * * * 3. Utilize, to the fullest extent possible, the policies and implementation controls of other elements of the Polk County Comprehensive Plan, and those of other governmental entities having jurisdiction, to further the conservation of natural resources. Starting at 6-3, Part VI discusses the Conservation Element's "Relationship to Other Plans." At 6-4, after stating that the Conservation Element will be largely implemented through the policies and programs of other comprehensive plan elements, Part VI provides: Land Use Element - This element will provide the overall framework for conservation [sic] potentialities through the manner in which land uses are distributed, arranged, and interrelated throughout Polk County. Policies and implementation programs of this element will determine the degree to which new development is properly related to soil types and capabilities, natural habitats, flood prone areas, wetlands and unique resource areas of the County. Land regulatory controls such as zoning, subdivision regulations and development impact reviews provide the basic tools for implementation of the policies of the Land Use Element. Starting at 6-5, Part VI discusses "Guidelines for Implementation." At 6-5, it points out: The nature of conservation policy, being of such broad application and diversity of interest, requires that its effective implementation utilize many approaches, techniques and procedures. Its application is carried out, for the most part, in an indirect way as a by-product of other more direct decisions and actions relation to the development and growth of the County. It is essential, therefore, that Polk County draw upon all possible alternative mechanisms and techniques which will lead to the effective conservation of its natural resource systems. Among the various approaches which Polk County may utilize to further its conservation objectives are the following. * * * Influence in the allocation of resources to achieve the objectives of the conservation plan. Control of events which determine resources allocation in keeping with the conservation plan. * * * Specific procedures and techniques which may be utilized to facilitate the implementation process include the following. * * * 7. Protect natural water bodies and adjacent wetland areas through the regulation of development densities and proper management of stormwater runoff. This would require a cooperative effort with the Water Management Districts in identifying flood plains for various flood frequencies. Polk County's Flood Protection and Surface Water Management Code. Polk County's Flood Protection and Surface Water Management Code was enacted as Ordinance 81-28 and was amended by Ordinance 85-07. Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code. Land Use, Density and Intensity. DCA alleges that the land use, density and intensity of the development Crowder proposes for the site is inconsistent with: (1) the section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships"; (2) a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources"; (3) Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE; and (4) Policy 2, Objective IV, "Residential Uses," in Part V of the LUE. 6/ As previously stated, the 1985 Plan is a policy plan that does not map land use classifications or densities or intensities of development. Crowder's Paradise Country Estates is consistent with the County's Zoning Code, which has not changed since before the 1985 plan, and Zoning Map. The development was not otherwise reviewed for land use, density or intensity. But it is clear that the 1985 plan does not condone exclusive resort to the zoning code to determine the appropriateness of the land use, density and intensity for development in the Green Swamp ACSC. See, especially, the section entitled "Density" in Part IV of the Conservation Element of the Plan. In the Green Swamp ACSC, especially, reference must also be made to the Plan itself. See Part VII of the LUE, entitled "Implementation." It is not found that all residential use on the Crowder property would be, in itself, inconsistent with the 1985 Plan. But, taking into consideration all of its land use, density and intensity provisions, it must be found that the development order issued in this case, especially at its level of density and intensity and especially in the manner of its issuance, is inconsistent with the 1985 Plan. The crux of the problem with this development, like others in the Green Swamp ACSC already permitted by County development orders, is that, first, the 1985 comprehensive plan and the County zoning regulations in place at the time were inadequate and, second, the steps envisioned in the plan to make them adequate have not been taken. For the plan and the zoning regulations to be adequate, and for a development order for a project in the Green Swamp ACSC in Polk County to be consistent with the 1985 comprehensive plan, either: (1) the plan must be amended to map land use classifications, densities and intensities of development in the Green Swamp ACSC; (2) the zoning code must be amended as envisioned in the comprehensive plan for the Green Swamp ACSC; or (3) the County must evaluate development orders for projects in the Green Swamp ACSC on a case- by-case basis for consistency with the comprehensive plan. None of these three possibilities happened in this case. 7/ Flood Plain Delineation. Paragraph 12 of the DCA Petition alleges that the Crowder development violates Policy 10 of Objective III, "Natural Resources," of the LUE: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Specifically, it is alleged that the use of a Federal Emergency Management Agency (FEMA) undetailed "A" zone to map the flood prone area on the site, and the failure to perform a detailed study, did not comply with the Flood Disaster Protection Act of 1973. Other allegations in the DCA Petition also implicate the delineation of the flood prone areas on the site. See, (5) Ground and Surface Water Quality, below. A FEMA "A" zone is the zone depicting the area determined by FEMA to be flood prone. In this context, FEMA defines a "flood prone" area as an area flooded in a 100-year, 24-hour storm. At the time Polk County reviewed the Crowder project for approval of the roadway and construction drainage plans, FEMA was requiring that a detailed study be performed to delineate the flood prone area. Polk County apparently was not aware of this requirement and was not enforcing it. Nor, apparently, was Crowder's engineer aware of it. In any event, Crowder did not have a detailed study performed to delineate the flood prone area on the site, and the County did not require it. In approximately March, 1992, Polk County received a written communication from FEMA advising of the requirement for a detailed study of the flood prone area in the case of developments like Crowder's. Polk County now requires compliance with this FEMA requirement. Crowder did not rely simply on the FEMA undetailed "A" zone to map the flood prone area on the site. Crowder's engineers used the existing undetailed FEMA maps as a starting point for determining base flood elevations. The engineers digitized the areas which had been designated as flood prone on the FEMA panels. The engineer then overlayed the digitized FEMA map with the on- site wetlands survey of the property, which had been field-staked and field- shot. Topographical field shots of the property which had been conducted throughout the site at one foot intervals were also overlayed on the digitized FEMA map. In addition, the engineer took into consideration mapped wetlands soils and compared flooding conditions which had occurred on adjacent property to assess whether all areas actually prone to flooding had been characterized as flood prone on the FEMA map. The methodology used by the project engineers was based on sound engineering practices. Nonetheless, it does not qualify as a "detailed study" as far as FEMA is concerned. A "detailed study" would include the application of a computer program that would "route" hypothetical flood waters onto and through the property to ascertain flood elevations in different stages of the hypothetical flood. It is not possible to determine how a detailed study would change the delineation of the flood prone area in Crowder's proposal. The total area of flood prone area could either increase or decrease; it could increase in some places and decrease in others. As it is, several of the lots platted in the Crowder development would be entirely within both the FEMA undetailed "A" zone and the flood prone area mapped by Crowder's engineers. Ground Water Recharge. DCA alleges that platting Paradise Country Estates will adversely impact recharge of the Floridan Aquifer, contrary to Policy 9 and 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. In the vicinity of the project site, the Floridan Aquifer comes to within 35 feet approximately of the ground surface. Above the Floridan Aquifer is a shallow aquifer, which rises to within approximately 12 inches of the surface. There is a layer of clastic soils (sand and clay) between the surficial aquifer and the Floridan Aquifer. This confining layer slows the rate of recharge to the Floridan. As a result, the project site is in an area having low, or even very low, to moderate recharge capabilities, at best. USGS Professional Paper 1403-E, which was released in 1990, uses groundwater modelling to quantify recharge rates, instead of using qualitative terms such as "low," or "poor," "moderate" and "high" to describe recharge capabilities. USGS Professional paper 1403-E reports that many areas in the Green Swamp previously labeled as good, moderate or high recharge areas are actually capable of only recharging at rates of 3 to 4 inches per year. The subject property appears to be in the 2 to 3 inch range per year for recharge according to USGS Professional Paper 1403-E. Only three known sample soil borings have been taken on the project site. As a result, the extent of permeability and overall thickness of the confining layer between the surficial and Floridan aquifers is not certain. But there is no reason to believe that there are any karst features or other geologic faults in the area that would allow for direct connections between the surficial and Floridan aquifers. The soil borings that have been taken on the site verify the various geological surveys and studies describing the recharge capabilities in the area. Due to the site's limited capabilities as a recharge area, it is unlikely that the platting of this site will result in any significant reduction in its natural recharge rate. The project is not inconsistent with Policy 9 or 11, Objective III, "Natural Resources," of the LUE, or Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Individual Water Well Use. DCA alleges that the planned use of individual water wells in Crowder's Paradise Country Estates will impact the quantity of the Floridan Aquifer (and the surficial aquifer) contrary to Policy 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. The potentiometric level of the Floridan Aquifer protects the Floridan Aquifer from salt-water intrusion. Significant de-watering of the aquifer caused by large municipal or industrial wells extracting a high volume of water from the aquifer at an intense rate can lower the potentiometric pressure, thus increasing the potential for salt-water intrusion into the aquifer. (Furthermore, the lowered potentiometric pressure creates a hydraulic gradient which encourages surface waters to percolate downward at a faster rate due to the decreased pressure in the Floridan Aquifer. See the preceding sections on Ground Water Recharge and the following section on Ground and Surface Water Quality.) Large municipal, industrial or agricultural wells which exceed 6 inches in diameter must obtain consumptive use permits from the SWFWMD. The Water Management District takes into account what the District determines to be a safe yield per acre when issuing a consumptive use permit. Small, residential wells are not subject to this permitting process as their impacts are much smaller and less intense, and not a concern with regard to their effect on the potentiometric pressure. For this reason, some coastal areas have begun using smaller, individual wells as an alternative to larger municipal wells. The Floridan Aquifer is replenishing itself fast enough for residential wells not to "de-water" or "draw down" the aquifer's supply of ground water. Residential wells do not lower the potentiometric pressure of the Floridan to a significant degree. Nor would they affect the normal supply of ground water, or contribute to salt-water intrusion. Pumping tests performed within two to three miles west of the project site which utilized several residential-size wells support the foregoing conclusions. For these reasons, it is found that the development will not adversely impact the normal supply of ground water and thus will not interfere with the functions of the potentiometric high of the Floridan Aquifer, including its protection against salt-water intrusion. Since the water wells would pump only from the Floridan Aquifer, they would not impact the supply of surface water. In regard to the use of water wells, the project is not inconsistent with Policy 11, Objective III, "Natural Resources," of the LUE, or with Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Ground and Surface Water Quality. DCA alleges that Paradise Country Estates will result in unacceptable contamination of the Floridan Aquifer, the surficial aquifer, and the surface water (particularly the Withlacoochee River) contrary to Policies 9, 10 and 14 of the "Water Resource Objective" of the Conservation Element. Paragraph 20 of the DCA Petition alleges that the use of individual on-site disposal systems (OSDS), or septic tank systems, in violation of Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code), 8/ in particular, will be part of the cause of the unacceptable contamination (other causes being from lawn and garden maintenance and automotive wastes.) On-Site Disposal Systems. Chapter 10D-6, Florida Administrative Code, sets forth requirements for the use of on-site waste disposal, or septic tank, systems in the State of Florida. That chapter, which is administered by the Department of Health and Rehabilitative Services ("HRS") through local health departments, provides construction standards for the installation of on-site waste disposal systems. The septic tank serves as a holding tank designed to separate solids and floatable materials and allows anaerobic digestion of organic materials. The remaining effluent exits the tank into the soil infiltrative process, which is referred to as the drainfield. The drainfield is composed of gravel placed around perforated pipes, which are designed to evenly distribute and release the effluent into soil material where the effluent undergoes aerobic digestion. Eventually, any constituents remaining in the effluent which have not been absorbed by the root zone or otherwise decomposed reach the subsurface waters which are referred to as the surficial water table. Each individual lot owner will be required to obtain a permit from the local health department prior to installing an on-site waste disposal system. Prior to issuing a permit, HRS inspects each site to assess soil limitations and to conduct a percolation test to determine the seasonal high water table for the site. Because the soils on the site are severely limited for filtration purposes and the high water table is only 10 to 12 inches below the surface, individual lot owners will be required to mound their on-site waste disposal systems to overcome these limitations. Although the fill used to mound the systems will be comprised of suitable soils, it is possible that the foreign soils will absorb moisture from the existing soils on this site, a phenomenon referred to as capillary fringe affect. This phenomenon can cause those portions of the fill which come in direct contact with the existing soils on the site to lose their filtration capabilities. Unless the fill becomes saturated from other sources, it is unlikely that capillary fringe affect will render the filtration process ineffective. The effects of capillary fringe affect can be lessened by mixing fill with soils found on the site, a practice undertaken by contractors when installing on-site waste disposal systems. In addition, increasing the amount of fill used to mound the system would decrease the potential affects of this phenomenon. 9/ Floridan Aquifer Water Quality. In some areas of the Green Swamp, the Floridan Aquifer is actually considered a surficial aquifer since no confining layers of soil or clay separate the subsurface water from the Floridan Aquifer. These areas would typically be characterized as areas with high recharge capabilities (or high potential for contamination). However, throughout the project site, a confining layer exists which is composed of clayey sands which have a very low permeability. Therefore, there is relatively little interaction between the surficial aquifer and the Floridan Aquifer on this particular site. For this reason, the use of individual on-site waste disposal systems on this site would pose no significant risk to the water quality of the Floridan Aquifer. Surficial Aquifer and Surface Water Quality.-- As for the surficial aquifer and surface water quality, Chapter 10D-6, Florida Administrative Code, requires on-site waste disposal systems be located at least 75 feet from waterbodies. Normally, and when the systems are operating properly, this assures that adequate filtration and decomposition occurs before wastewater reaches surface waters on or near the site. But, in the case of the Crowder proposal, it is necessary to consider that at least some of the mounded systems will be subjected to flooding and will become saturated. Even based on the analysis by Crowder's engineers, 51 of the lots in Paradise Country Estates are entirely flood prone; there is no place to put an OSDS on those lots that is not flood prone. If a "detailed study" had been done, it is possible that more lots would be entirely within the flood hazard zone. Other lots not entirely within the flood zone may not be able to accommodate an OSDS on the part of the lot not within the flood zone. If the OSDS mound is saturated during flood conditions, the system will fail, and untreated waste, or inadequately treated waste, will be released into the surface flood waters. This waste water will move laterally across the project site. Roots may absorb some nitrates or other organic compounds; 10/ otherwise, the waste water and its constituents will remain in the surface water. Lateral movement across the site generally will be slow, as the site is relatively flat. Some of the waste water and its constituents will get into the surficial aquifer. There are ditches or canals alongside and on the site that will direct the rest of the surface water into Pony Creek and other tributories of the Withlacoochee River, an Outstanding Florida Water approximately three and a half miles to the north. The Department of Environmental Regulation issued a dredge and fill permit for the project's road network's impact on wetlands on the site. But it did not pass on the use of OSDS in the individual lots. It also erroneously referred to the Withlacoochee as a natural Class III, instead of an Outstanding Florida Water. See F.A.C. Rule 17-302.700(9)(i). The Southwest Florida Water Management District (SWFWMD) issued a surface water management permit for the project. In evaluating a permit application, SWFWMD considers surface water quality. But the focus of SWFWMD's inquiry is the pre- and post-development peak flows. Also, when it considers water quality, SWFWMD considers the impact of site alteration on water quality, not the impact of the use of OSDS on the site. In addition, the Crowder project was reviewed under special criteria for low-density rural subdivisions that do not require the submission of as much information. It was not clear from the evidence precisely how SWFMD evaluates water quality under those criteria. For these reasons, based on the evidence, it cannot be said that the Crowder project's OSDS will be meet the minimum standard of being "located to avoid impairment to them or contamination from them during flooding," as required by Section 5-1(6) of Polk County Flood Protection and Surface Water Management Code, or that the project will "protect the normal . . . quality of ground and surface water . . . necessary for the protection of resources of state and regional concern," as required by Policy 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Finally, the project will not "protect or improve existing ground and surface-water quality," as required by Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan. Other Appeal Issues. Except as set forth above, the Crowder development did not violate the 1985 comprehensive plan and Flood Protection and Surface Water Management Code provisions cited in the DCA Petition. Agency Practice - Other Development in the Area. As previously described, Evans Acres, to the west of the Crowder site, was approved by DCA in 1983. (See Finding 10, above.) As approved, it was comprised of 48 lots on approximately 1,290 acres (a density of one unit per 27 acres). The original lots ranged in size from 5 to 60 acres. Unbeknownst to the DCA, individuals apparently have since split their lots and many of the existing lots are 2 to 5 acres in size. A proposed development known as Turkey Creek is located between the project site and Evans Acres. Turkey Creek is comprised of approximately 57 lots on 170 acres with a gross density of 1 unit per 3 acres. The physical characteristics of the Turkey Creek property, including the abundance of wetlands and floodplains, are essentially the same as the proposed project site. DCA appealed Turkey Creek in June of 1992. However, in that case, the County had been approximately two years late in rendering the Turkey Creek development order to the DCA. Meanwhile, the developer incurred development expenses and already had constructed roads and drainage facilities for the development. The developer, the County and DCA executed a settlement agreement which allows the development to proceed according to the original construction plans, but requires homeowners to install dual septic tank systems and have their septic tanks cleaned and inspected every three years. Several other developments, which are in the general vicinity of the project site and have many of the same physical characteristics, including Yearling Trace and Buck Hill, have been appealed by DCA. Yearling Trace is comprised of 108 units on approximately 544 acres. Buck Hill is comprised of 55 units on approximately 214 acres. Those projects were appealed by DCA in June and April, 1992. In some of these cases, the County did not timely render development orders to DCA in a timely manner. In the case of Buck Hill, the DCA had been mailed an unapproved copy of development plans in October, 1990; in early 1992, DCA contacted the County to inquire, as no County-approved development plans ever had been sent to the DCA. In many of these cases, substantial development expenses had been incurred; in some cases, roads and drainage facilities already had been constructed. DCA decided to settle the pending appeals in which the County was late rendering the development order, and in which the developer already had constructed roads and drainage facilities, consistent with the Turkey Creek settlement. In cases where the County was late rendering the development order, but the developer had not already constructed roads and drainage facilities, the DCA determined to settle not only for stipulations to upgrade the OSDS, as in the Turkey Creek settlement, but also for requirements that a "detailed" flood zone study be done, in accordance with the FEMA requirements. Prior to the DCA appeal, Crowder had expended approximately $31,000 in permit fees. In addition, he has incurred development costs, primarily for engineering fees and related services. Through the time of the final hearing, he had spent approximately $99,000 on engineering fees and services. (The evidence was not clear how much had been incurred by the time of the DCA appeal.) However, the County was not late in rendering the Crowder development order, and Crowder has not constructed roads or drainage facilities. In view of the different circumstances in Crowder's case, DCA's prior agency practices do not compel that Crowder's development be treated in the same manner, i.e., be settled on the same terms, as the Turkey Creek and the others. DCA has argued that FLWAC's Final Order in the case of Dept. of Community Affairs v. Narbi International Company, Inc. and Lake County, 14 FALR 3223 (1992), controls this case and requires the Crowder development order to be overturned on appeal. Narbi involved development Green Swamp ACSC, albeit in Lake County. Factually, there are many differences between Narbi and this case. The Narbi development order was a rezoning from agricultural with a residential density of up to one unit per five acres to a residential planned unit development (PUD) zoning with a density of one unit per 1.35 acres. Also, Lake County's comprehensive plan had an "urban containment policy," which DCA equated with its non-rule policy preventing "urban sprawl" or "leap-frog development." Thirdly, in Narbi, it was found that a geologic fault existed on the project site which allowed a direct connection from the surficial aquifer to the Floridan Aquifer. Because of the factual differences, Narbi does not control the outcome of Crowder's case. Conditions for Approval. Based on the testimony of its witnesses, DCA has proposed that, notwithstanding its deficiencies, the Crowder project can be approved if its density is lowered to between one unit per ten acres and one unit per 20 acres. The rationale of DCA's witnesses seems to be that the proposed lower density, in and of itself, would cure at least the most significant of the deficiencies. Since the Crowder development order under review was for approval of particular road and drainage plans, the plans would have to be redrawn at the lower density and resubmitted for approval by the County subject to the final order to be entered in this case. It is not possible for the Commission to approve, on condition of lowered density, the plans that were the subject of the development order in this case.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Florida Land and Water Adjudicatory Commission enter a final order rescinding and denying approval for the development order in this case. RECOMMENDED this 10th day of March, 1993, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 10th day of March, 1993.
Findings Of Fact The property upon which Petitioner seeks a variance from the normal requirements for attaining a permit to install an on-site sewage disposal system is found in Leon County, Florida. Specifically, it is located at Lot 4, Block A, Killearn Lakes Unit I. The relative position of this lot in the subdivision is depicted within Petitioner's Exhibit 1 and Respondent's Exhibit 2 admitted into evidence. Respondent's Exhibits 3 through 5 are photographs of the site. Petitioner intends to construct a 1,200 square foot residence. As the photographs depict, some preparation has commenced to the extent of lot clearing and other site work where the home would be constructed. Killearn Lakes Unit I is a pre-1972 subdivision. When the development commenced, it was anticipated that a community sewer system would be utilized, as contemplated by the plans submitted in April, 1971. Subsequently, some lots within the Killearn Lakes Unit I were allowed to be developed with the use of on-site sewage disposal systems, namely septic tanks. There are 150 lots in that category. In 1979, with the advent of certain rules under Chapter 10D-6, Florida Administrative Code, the development was allowed to proceed on the basis of four septic tanks per acre. Over time, Killearn Lakes Unit I experienced a history of failures with on-site sewage disposal systems. The failures were promoted by problems with the "sheet flow" drainage system and its patterns of dispersion of storm water runoff, problems of soil permeability and abnormally high wet season water tables, referred to as perched water tables. This resulted in sewage backing up into homes and flowing out onto the ground in the yards of the residences, into streets and onto adjacent neighbors' lots. The problems experienced were widespread within the Killearn Lakes Unit I. This seepage of raw sewage presented a health hazard, as it would on any occasion. Among the residences confronted with this dilemma was Lot 5, Block X, adjacent to the subject lot. Persons residing in that home had to undertake alternative means of on-site sewage disposal to have that system function properly. This included relocation of the apparatus, mounding, use of an aerobic system, and use of pumps to insure that the waste being disposed did not back up into the conveniences within the home. Witnesses who appeared at the hearing described the series of corrections in some detail. Those witnesses included a former owner of that residence and others who had a technical understanding of the problems in that system. The problems in Killearn Lakes Unit I related to on-site sewage disposal systems became so extreme that the Leon County Commission declared a moratorium on the installation of on-site septic tanks in that development. This occurred in 1987. In order to better understand the problems in the Killearn Lakes subdivision, to include Killearn Lakes Unit I, a study was commissioned. That report is referred to as Killearn Lake Waste Water Disposal Study of June, 1987. A copy of the report is found as Respondent's Exhibit 6 admitted into evidence. It was prepared for the Leon County Board of County Commissioners and prepared by the Leon County Public Health Unit with the assistance of the Leon County Department of Public Works, Leon County Building Department, Ochlockonee River Soil and Water Conservation District, Northwest Florida Water Management District, Tallahassee-Leon County Planning Department, Florida Department of Health and Rehabilitative Services, and Florida Department of Environmental Regulation. Some of the highlights of that report concerned the observation that the septic tank systems do not work adequately and that the more systems that are placed the greater the problems. It noted that the nature of the drainage system in this area is a contributing factor to the failures. The soil's poor permeability, relating to the Dothan series of soils in the area which have slow permeability, contributed to the problem. Perched water tables were found above the expected levels for the wet season water tables. They also presented a problem, as did excessive slopes in some areas. In particular, it was noted that 80% of the lots sampled in Killearn Lakes Unit I had severe limitations on the use of on-site sewage disposal systems. Ninety-three per cent of the lots sampled in Block X received excess runoff from other lots and roads at higher elevations. It was noted that French or curtain drains alone would not significantly reduce perched water table complications because of the low permeability of the soils. It was reported that the overall housing density of Killearn Lakes is not particularly high, but the individual lots are small, approximately 1/4 acre in size. This, taken together with the fact that the "sheet flow" concept of storm water management contemplates that the runoff will cascade across the terrain conforming to its contours, means that some small lots will be inundated. This uncontrolled runoff contributes to septic tank problems in that the tanks fail when the soils around them become saturated. The report notes that if there was a different designed drainage system, the impact on septic tanks would be less. The report notes that if something is not done to modify storm water runoff, drainage problems will persist. Consequently, septic tank failures will continue to occur. Concerning the water tables, the soil testing, which was done in Killearn Lakes Unit I, in which the predominant soil is Dothan type, demonstrated that the borings which located mottling of the soils at the expected level of the wet season water table were inaccurate. These indicators did not correspond to reality in that the true water tables were found 12-20 inches above the expected level of the average high water, as seen in the mottling. This phenomenon was revealed in 42% of the lots evaluated which had Dothan soils. The report recommended, among other measures, that no new sewage disposal system permits be issued in Killearn Lakes Unit I until a storm water system had been constructed and demonstration made that the system would collect storm water and thereby lower the perched water table on specific lots under review. The ultimate response to the question of permits for on-site sewage disposal systems in Killearn Lakes Unit I was spoken to in a Resolution of July 14, 1987 entered by the Leon County Board of County Commissioners. A copy of the resolution may be found as Respondent's Exhibit 1 admitted into evidence. It was resolved that the permits for on-site septic disposal systems be reviewed by the Leon County Public Health Unit on a case-by-case basis in accordance with criteria announced at Chapter 10D-6, Florida Administrative Code. This effectively lifted the moratorium. The subject request for installation of an on-site sewage disposal system was reviewed in keeping with the policy decision set forth in the resolution. Respondent's Exhibit 6 admitted into evidence includes a copy of a survey made by the Homeowners' Association for Killearn Lakes, also admitted as Petitioner's Exhibit 1. As part of the study commissioned by the Leon County Board of County Commissioners, it has some relevance in portraying the dimensions of the problem. Those dimensions are better understood by resort to the color scheme which is found in Petitioner's Exhibit 1. It depicts the problem lots in red color, those lots without problems in green color, and the lots upon which no report was made in orange color, as well as vacant lots, to include the subject lot, which have no color scheme. This latter category indicates no participation in the survey. The door-to-door personal survey conducted by Rod Moeller and testified about at hearing does not diminish the impression of the seriousness of the problem with on-site sewage disposal system failures in Killearn Lakes Unit I, which the 1987 study by the Leon County Board of County Commissioners identified. This survey by Mr. Moeller was in a limited area, more specifically related to the portion of Killearn Lakes Unit I nearby the subject lot. The findings of the 1987 study commissioned by the Leon County Board of County Commissioners are accepted as accurate. Eanix Poole, Administrator of Environmental Health for the State Health Office testified at the hearing. He pointed out that the failure rate in the subdivision under question for on-site sewage disposal systems is 25%, as contrasted with the statewide rate of less than 1/2%. He identified the fact that those failures relate to backups within the home and seepage onto the ground. He verified that these events constitute health problems, especially given the number of failures. He sees the lot in question here as being particularly vulnerable to problems given the drainage patterns and its location at the bottom of two hills. The lot in question receives runoff from the two adjacent lots as well. Mr. Poole sees the subject lot as more vulnerable in the wet season and does not believe that any alternatives that are available for placement of the system on the site would sufficiently alleviate the potential failure of the system to make it a successful arrangement. What he sees is a lot in the path of a natural drainage of tremendous quantities of storm water runoff, coupled with poor soil conditions related to soil absorption or permeability in an area where on-site sewage disposal systems have failed. He remarks that dry soils are needed to treat the sewage and that treatment cannot take place in a saturated soil environment. The effects of seepage of the sewage, according to Mr. Poole, is one which can degrade ground water. Mr. Poole is also concerned that the installation of the proposed on-site sewage disposal system above ground will have an adverse impact on the adjacent lots, one of which has already experienced problems. That refers to Lot 5, Block X. These observations by Mr. Poole, as reported, are accepted. Raymond Collins, an environmental administrator with the Respondent's health program office, also testified at the hearing. He is intimately aware of the problems in Killearn Lakes Unit I. Those problems began to occur in the winter of 1986 and continued into 1987. This related to problems with toilets and the seepage of effluent which was running onto people's property and into the streets. He notes a similar failure rate in Killearn Lakes Unit I to that observed by Mr. Peel when contrasted with the experience statewide. In the aforementioned period he received calls and reports from homeowners concerning system failures. In effect what was happening was that the on-site drain fields in Killearn Lakes Unit I would not accept more input and the raw sewage would bubble up and leach out onto the ground. He personally observed a dozen sites which had failures. He was responsible for the coordination of the July, 1987 study which has been mentioned. As a result of that study one of the steps which he took was to advise that staff investigating the permit application requests should elevate the estimation of the wet season water table by 12-20 inches. Mr. Collins agrees with the recommendation of the individual who was assigned to evaluate the application for permission to install an on-site sewage disposal system at the subject lot, who recommended that the application be turned down. Mr. Collins' description of the experience at Lot 5, Block X, related to his knowledge that the initial system had been replaced with an aerobic system, which also proved to be an inadequate on-site sewage disposal system. In 1988, he went to the home of the person living on that lot, and the aerobic system was not working. There was a light rain on that day, and there were problems in the drain-field area. When a soil boring was made to a depth of two feet effluent poured out. The perched water table had risen to a point in the bottom of the drain field, such that when a hole was punched, it provided a conduit for pressure to be relieved. The drain field that was experiencing this problem was not the original drain field. It was a replacement drain field. The drain field being observed was in the front of the lot, right below the ground. The suggestion to alleviate the problem was to move the drain field to the side of the yard and elevate it and install a series of small-diameter pipes. A pump was also needed to move effluent into the drain field, thus, avoiding a backup of the system into the home. He is unaware of any recent failures in the system at Lot 5, Block X. Mr. Collins emphasized the need for soil to remain unsaturated to provide effective treatment and that 24 inches of unsaturated soil is the minimum amount which would be acceptable. Mr. Collins commented about the nature of the subject lot and the fact that other lots drain through it. Mr. Collins commented that the design of the proposed septic tank does not assure success in the treatment of the waste disposed. Unlike the expert of the Petitioner, Mr. Peel, the problem is not that solids are blocking up the system. It is the failure of the soils to accept the volume of water which is being released from the chambers of the septic tank into the drain field. Mr. Collins does not believe that the use of water-saving appliances in addition to the limited size of the home to be built on the subject lot, installation of an aerobic system, and installation of an above-ground system, as proposed, would be successful and not pose a health risk from system failure. The problems would continue to be drainage patterns and poor soils. His remarks, as reported, are accepted as accurate. Terese A. Hegg, Environmental Specialist I with the Respondent's Leon County Public Health Unit, reviewed the application for variance to install the on-site sewage disposal system. She was familiar with the history of problems in Killearn Lakes Unit I before undertaking this assignment and has made more than 50 evaluations in that development. She observed that the "sheet flow" drainage of storm water does not provide reasonable management because it does not drain normally. She is aware that the wet season water table is as much as 20 inches above the normal indicators, as seen through mottling. Her analysis of this site is under the auspices of those requirements announced in Chapter 10D-6.044, Florida Administrative Code, having in mind that the subdivision plat was made before 1972. This includes an examination of the soil characteristics, history of flooding, and water table evaluations. At this site, she noted the poor permeability of the soil. She did soil borings to confirm the nature of the soils and to identify the water table. She took into account the abnormal perched water table that is above what the mottling would indicate as being the wet season water table. Ms. Hegg is concerned that the system on the adjacent lot, which is now functioning adequately, would not function adequately if the subject system was installed. She noted that the drainage pattern from the neighboring lots was toward the subject lot and that water would come from the left and the right lots adjacent to this lot, corresponding to Lots 5 and 3 as you face them. The drainage pattern would then proceed beyond Lot 4 and into a green area. In making her assessment of this application, she was aware of the problems with the on-site sewage disposal system at Lot 5, Block X. The appearance of saturated soil in the entire length of the boring and standing water on the lot is an indication of problems with percolation. The effluent will flow out and onto the ground if these soils are saturated. From her observations and based upon the history of Killearn Lakes Unit I and its failures regarding on-site sewage disposal systems, Ms. Hegg does not believe that the proposed system would successfully address sewage treatment and would promote a risk of on-site sewage disposal system failures for adjacent lots. Ms. Hegg acknowledged that the storm water flows could be diverted; however, she points out that the subsurface water cannot be diverted. Her account of this site and the acceptability of the request for variance as reported is accepted as accurate. Given the soil conditions and the wet season water table expected at this site, the proposed system will not present an adequate unsaturated soil depth for treatment of the sewage and untreated sewage may be expected to seep or leach out onto the ground. On May 22, 1990, Mr. Collins had written to Dr. Richard G. Hunter, Assistant Health Officer for Environmental Health, recommending the denial of the variance request. A copy of that correspondence may be found as Respondent's Exhibit 7 admitted into evidence. It details reasons which are similar to those described in this Recommended Order. As a consequence, even though the Advisory Review Variance Board had looked with favor upon the request for variance, that variance was denied by action of Dr. Hunter on May 30, 1990, which relied upon the insights of Mr. Collins, as described in his May 22, 1990 correspondence. A copy of the letter of denial may be found as Respondent's Exhibit 8 admitted into evidence. The purpose of this hearing was not to examine whether Respondent had abused its discretion in denying the variance. The reason for the hearing was to allow the parties to present their points in an adversarial setting, which allowed each party to explain its viewpoint anew. That was done, and the analysis provided by this recommended order ensued. In deciding the facts, these representations have been made with due regard to the remarks of James Earl Peel, an expert in the design of on-site sewage disposal systems, who had on his staff, Gary L. Wood, P.E. His methods in analyzing the issue of the suitability of the installation of an on-site sewage disposal system at the subject site do not coincide with the methods contemplated in Chapter 10D-6, Florida Administrative Code, which controls. This is especially significant in his approaches to soil characteristics and location of the wet season water table. As noted above, his belief that the problem is one of distribution of solids from the septic tank into the drain field overlooks the more significant problem of water volume discharge from the septic tank into the drain field. In fact, Mr. Peel indicated that he is unfamiliar with the requirements of septic tank design, as described in Chapter 10D-6, Florida Administrative Code. On balance, Mr. Peel's reports, in Petitioner's Exhibits 3 and 4 admitted into evidence and his in-hearing testimony, do not persuade that the system he recommends can be successfully operated at the subject site. His presentation and the overall presentation of Petitioner do not create a reasonable expectation that the system will not fail and create health hazards for the residents of Lot 4, Block X, and others in the vicinity. It is recognized that this lot owner faces a hardship that was not caused by Petitioner. It is also recognized that, pursuant to the stipulation of the parties, there is no intention by any entity to install a community system of sewage disposal. It is further recognized that there are no alternative methods that would seem to be successful in addressing the problem of the treatment of the sewage, as related in the previous findings. On the other hand, the discharge that could be expected from this subject system would bring about a condition in which the effluent presented a health risk to this applicant and other members of the public and has the potential to significantly degrade the ground or surface waters, although this latter circumstance has not been documented on other occasions and was not found to exist in the July, 1987 study commissioned by the Leon County Board of County Commissioners. In that report, it was specifically found that the surface water had not been compromised by the on-site sewage disposal system failures described in the overall report.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying Petitioner's request for variance from permit requirements and permission to install an on-site sewage disposal system at Lot 4, Block X, Killearn Lakes Unit I. DONE AND ENTERED this 20th day of November, 1990, in Tallahassee, Leon County, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 20th day of November, 1990. APPENDIX TO RECOMMENDED ORDER IN CASE NO. 90-4456 The following discussion is given concerning the proposed facts of the parties: In the discussion of the testimony of Mr. Poole, the relevant portions of that testimony are reflected in the facts found in this recommended order. Under the heading of testimony said to be attributable to Ms. Hegg, at paragraph 1, while it is recognized that a system might be installed that might not call for diversion of storm water onto adjacent neighbors' properties, the problem on site would remain and would be sufficient reason to reject the application. Moreover, it is not clear that it is the intention to install a system that would divert storm water from adjacent properties. Paragraph 2 under this heading is rejected in its notion that storm water would not have an influence on the proposed system. Paragraph 3 is rejected. Paragraphs 4 and 5 do not lead to the conclusion that sufficient unsaturated soils would be available for the treatment of disposed sewage during the wet season, nor does the representation at paragraph 6. Paragraph 7 under that heading is contrary to facts found. The paragraphs under the reference to James Earl Peel, in those five paragraphs, while accurately portraying the opinion of Mr. Peel and Mr. Wood, does not lead to the conclusion that the application should be granted. Under the heading "Rod Moeller" in the first paragraph, the information provided at hearing and under weather reports does not satisfactorily establish what the rainfall circumstance may have been at the subject property 72 hours before January 24, 1990, as referred to in paragraph 1, nor can it be said that the rain experienced in the overall area contemplated by the attached weather report to the argument by Petitioner was a 25-year storm event. The comment at paragraph 3 under this category that the on-site sewage disposal systems in neighboring lots are functioning fine since modifications in the advent of hurricane "Kate" is contrary to facts found. Under the heading "Ray Collins" in paragraph 1, this proposed fact has no relevance in that the question is the appropriate function within Killearn Lakes Unit I, not at an undisclosed site away from that area. Respondent's Facts These facts are subordinate to facts found.

Findings Of Fact By an application filed with the Department of Environmental Regulation on October 28, 1980, Pinellas County requested a dredge and fill permit to- construct a road and bridge crossing with an associated stormwater treatment system in connection with the improvement of County Road No. 1 across Curlew Creek and its wetland flood plain. The specific location of the project is in Section 12, Township 28 South, Range 15 East, in the City of Dunedin, Pinellas County, Florida. The project will involve the dredging of approximately 2,639 cubic yards of soil and include the placement of approximately 1,605 cubic yards of fill in the creek bottom. After an evaluation of the initial application the Department issued a letter of intent to deny the application on March 17, 1982, but the denial suggested several modifications to the project which were accepted by the County when it filed an amended application on September 30, 1932. It is on the basis of this amended application that the Department issued its notice of intent to grant on November 5, 1982. The County's initial application was complete before February I, 1982, the effective date of Chapter 17-25, Florida Administrative Code, the Department's new stormwater discharge rules. The Petitioners jointly own real property on which they reside immediately to the west and downstream of Curlew Creek. Their property is riparian to the creek. Curlew Creek is a natural water body which runs from near U.S. Highway 19 in a westerly direction to the Gulf of Mexico in Dunedin, Florida. It is an unnavigable Class III water of the state. At times it carries a heavy stormwater runoff load and passes private residences such as Petitioners' which border the creek in many areas. During design storm events there has been flooding when the creek exceeds its historic flood plain. That flooding has come up into Petitioners' back yard. At the project site where the creek now runs under the existing span for County Road No. 1, the creek is approximately 25 feet wide and 2 feet deep. The creek bottom is flat and consists of deep fine sand. The banks are well vegetated with a dense scrub layer and many large trees. This vegetation provides good soil stabilization and prevents erosion of the creek banks. Curlew Creek is presently traversed by County Road No. 1 over a two- lane bridge. Because of increased traffic flow the County proposes adding another bridge span to carry two more lanes of traffic. When the additional two lanes are complete the center line of the entire bridge complex will be moved to the west of its present location and therefore be closer to Petitioners' residence. Petitioners primary concern in opposing the project is their belief that when completed the project will increase the potential of Curlew Creek to flood their land. Curlew Creek, which generally runs in an east-west direction, takes a sharp bend to the south on the downstream side of the existing bridge. It later resumes its course to the west toward St. Joseph's Bay and the Gulf of Mexico. The creek's rapid change of direction underneath the bridge caused some confusion when the Department of Environmental Regulation issued its notice of intent dated November 5, 1982, to grant the requested dredge and fill permit. Condition number one for issuing the permit stated "The existing vegetation in an area more than 50 feet up and downstream from the bridge railing will not be disturbed except in the area of detention pond number 3 on the northeast side of the bridge." The author of the notice had intended that the condition mean vegetation would not be disturbed any further than 50 feet to the east or 50 feet to the west of the planned bridge railing, and not 50 feet upstream or downstream. The project plan is to remove a small sand spit which projects into the creek from the east bank immediately to the south of the bridge. Additional minor dredging is planned to smooth the water flow through the bridge area. Fill will be deposited to also provide a smoother water flow and consequently cut down on the eddies which presently arise under the bridge. The result of improved stream flow will be a reduction in the erosion of the creek banks and a lessening of turbidity in the creek water. Because the construction proposed will result in removal of certain vegetation along the creek bank which now provides soil stabilization, the County plans to use wet sand cement riprap or gabions for slope protection to stabilize the soil. Either method provides adequate erosion protection to ensure that the standards for Class III surface waters of the state will not be violated if the conditions of the proposed permit are followed. The expanded stormwater runoff facilities which are part of the project, as modified and subject to the condition in the Department's letter of intent to grant, will not have a significant impact on the water quality of Curlew Creek. These facilities provide adequate retention and settling capacity to ensure that the stormwater which eventually discharges into the creek will not cause pollution.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That the Department of Environmental Regulation enter a Final Order approving the application of Pinellas County for a dredge and fill permit in order to construct the above described project in accordance with the conditions set out in the Department's letter of intent to grant dated November 5, 1982. DONE and RECOMMENDED this 24th day of October, 1983, in Tallahassee, Florida. MICHAEL P. DODSON Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 24th day of October, 1983.
The Issue The issue to be resolved in this proceeding concerns whether the Petitioners are entitled to an on-site sewage disposal system ("OSDS") permit in consideration of the statutes and rules relating to approval of permits cited and discussed herein, or whether they are entitled to a variance from the strict requirements of those statutes and rules so as to allow the installation of the OSDS on their property near the Suwannee River. See Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioners purchased real property located in Levy County, Florida, in 1967. That property is located in the unincorporated community of "Fowlers Bluff" on the east bank of the Suwannee River. The property is more particularly described as the west one-half of Lot 13, and the east three- quarters of Lot 14, Treasure Camp Addition, Unit 3. The lot in question is approximately 100 feet by 125 feet by 197 feet in size. There is adequate unobstructed area available for the subject system's installation, according to Respondent's Exhibit NO. 1 in evidence. The lot is part of a subdivision which was platted prior to 1956. The subject lot has available a potable water source from the public water system. Consequently, the lot is of sufficient size to meet the quarter-acre minimum requirement for the installation of septic tank and drain-field systems in situations where lots have potable water available from a public water system, which is the case in this circumstance. The effective soil depth at the drain-field installation site is greater than 42 inches below the bottom surface of the proposed drain-field trench or absorption bed location. That is, 72 inches of sand, which is a "slight limited soil" and appropriate for such installations, exist at the site. The wet season water table was shown to exist at 26 inches below the grade level. The wet season water table, pursuant to Rule 10D-6.047(2) Florida Administrative Code, must be at least 24 inches below the bottom surface of the drain-field trench or absorption bed. Consequently, the wet season water table in this situation is not sufficient in depth for the proposed installation to meet this provision of the Respondent's rules. The Petitioners seek to gain approval for a system to serve a single- family residence of approximately 2,000 heated and cooled square feet, with a "standard" 350 gallons per day sewage flow. The residence would contain three bedrooms, as presently envisioned. The Petitioners' Exhibit NO. 1 establishes a benchmark elevation for the grade level of the proposed OSDS installation site of 7.48 feet above mean sea level ("MSL"). The actual grade elevation is 0.8 feet below that benchmark elevation. That is, the elevation of the grade of the property is 6.72 feet above MSL at the proposed installation site., The ten-year flood elevation for the proposed installation site, however, is 9 feet above MSL, as verified by a report prepared by the Suwannee River Water Management District, admitted into evidence and which was submitted to the Respondent by the Petitioners in the application process. The property also lies within the regulatory floodway of the Suwannee R for purposes of Rule 10D-6.047(6), Florida Administrative Code. Testimony by Mr. Parker, as well as the Respondent's evidence through Mr. May, establishes that the property in the past has had approximately 30 inches of fill placed on it. Because of this, the grade level elevation is in fairly-close proximity to the ten-year flood elevation and because of the prevailing slight limited soil type down to a depth of six feet, the property was shown to be generally amenable to installation of a mounded septic tank and drain-field disposal system, which mounding could raise the property so that the bottom of the drain-field trench or absorption bed would not be within the ten- year flood elevation. As Mr. May indicated by letter dated March 1, 1990 to Mr. Parker, the lot could be filled utilizing slight limited soil so that a mound to contain the septic tank and drain field of no more than the required 36 inches, pursuant to Rule 10D-06.0493(b), Florida Administrative Code, might be utilized. That letter, in evidence, also indicates that if the lot, or a portion of it, is filled, the fill shall extend a minimum of 20 feet in all directions beyond the perimeter of the mound base. The lot was shown to be of sufficient size to accommodate such a perimeter area of fill. In that same letter, Mr. May advised Mr. Parker that he had the right to request a variance from the provisions of Chapter 10D-6 Florida Administrative Code, since his property, in Mr. May's view, did not meet the criteria in that regulatory chapter for the issuance of an actual permit. The record does not reflect that an actual variance application had been filed, however. It would thus seem that this property is amenable to a reasonable alternative solution to a conventional, subterranean septic tank and drain-field system by the use of the "mounding process". That alternative, however, pursuant to Rule 10D-6.047(6), Florida Administrative Code, would require the certification of a registered professional engineer to the effect that the installation of such a mound could be done ,in such a way as not to raise the "base flood" level. This is because the property lies within the regulatory floodway of the ,Suwannee River; and under the rule section cited last above, a `certification must be made that the base flood level will not be raised by such a mounded system installation for property lying in the regulatory floodway. The Petitioners adduced no such engineering testimony or evidence to establish that if the system were installed with the mounding process, the base flood level would not be raised. In addition to the evidence culminating in the above Findings of Fact, the Petitioners offered general testimony to the effect that they had purchased the property in question for purposes of both having a "retirement rest egg" and a place to live should they choose to live on the property. The Petitioners established that they, like numerous other OSDS permit applicants in similar proceedings, are undergoing a hardship because they purchased the property for residential purposes or for re-sale for residential purposes and cannot construct a residence and live on the property or sell it for that purpose because of the inability to obtain a permit. The Petitioners' proof, in terms of the variance criteria noted below, is inadequate to show that there are no alternative systems available which will adequately dispose of and treat the sewage to be expected, nor did the Petitioners establish that installation of the system presently proposed would only constitute a minor deviation from the requirements of the Respondent's OSDS permitting rules, in terms of having no adverse effect on the health of the Petitioners, the general public, or upon the surface or ground waters involved in the vicinity of the site. Although the Petitioners did not formally apply for a variance, no adequate proof in these two particulars was offered so as to justify the grant of a variance; however, it was established that the property was platted prior to 1972 for purposes of the relaxed consideration embodied in the variance rule and statute for this circumstance. The Respondent now asserts, however, that the Petitioners should not be accorded the opportunity to avail themselves of the variance procedure because of the Respondent's interpretation of the Governor's Executive Order 90-14, which it opines precludes it from granting any variances or permits for OSDS's within the ten-year flood elevation. The Governor's Executive Order, which incorporated the "Suwannee River Task Force" recommendation to preclude such systems beneath the ten- year flood elevation, was entered on January 17, 1990. The Respondent has, in effect, interpreted that Executive Order as precluding it from exercising its discretion to entertain and grant or deny variance applications.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying the application for the subject permit, without prejudice to a later application for a variance or a later application for an OSDS permit based upon additional and changed facts and circumstances.

The Issue Whether the Department of Environmental Regulation should grant a dredge and fill permit to James N. and Janice E. Nash authorizing removal of eleven cubic yards of soil, installation of five 24-inch culverts in lieu of two 18- inch culverts, and placement of 19 cubic yards of limerock in and around the bed of an unnamed creek near the point it reaches the Alford Arm of Lake Lafayette in Leon County, Florida?
Findings Of Fact More than a thousand acres in eastern Leon County comprise the drainage basin giving rise to the unnamed stream that intermittently wends its way across the Alvarez property, crosses the 30-foot wide "tongue" of the Nashes' lot, and traverses the Saltiels' land on its way to the Alford Arm of Lake Lafayette (unless it reaches Alford Arm earlier because rain or other conditions have raised the lake, moving the water's edge upland.) Although neighbors allow them ingress and egress by another route, when flooding makes the roadway impassable, Mr. and Mrs. Nash have no legal right of access other than by the private road which crosses the intermittent stream. In addition to wetlands on either side, part of the streambed, 15 feet wide where it meets the roadway, was originally filled in 1968, when the private drive was built. The strip of land, 30 feet wide and 700 feet long that underlies most of the private road, joins the part of the parcel where the Nashes' house stands to Deep Wood Trail, the public thoroughfare which the private road enters. Leaving a car on the Deep Wood Trail side of the stream, wading across to the other side, and hiking to the house pose difficulties for Mr. Nash, who has muscular dystrophy. Under some conditions, the roadbed acts as a dam. When the lake is low, water flowing downstream may be impeded. When the lake is high, backwater moving in the other direction may be impeded. Of the two culverts installed when the private road was constructed, each with a diameter of 18 inches, only one permits water to flow through now, and even it is partially clogged. When Lake Lafayette rises above 45.3 feet NGVD, Alford Arm spills over the terrain between it and the Nashes' road, and reverses the flow in the streambed where it intersects the roadway. The "invert of the stream at the subject crossing [is] 44.3 feet [NGVD]." T.402. The roadbed is submerged in the vicinity of the stream when Alford Arm rises above 46.7 feet NGVD. The Nashes propose to excavate the streambed (about two and a half feet deep in the natural channel on either side of the existing fill) where it crosses (diagonally) the Nashes' private road, remove the existing culverts together with the soil in which they are embedded, install five culverts, each 24 inches in diameter, in their stead, install cement bag riprap at the ends of the culverts, remove 11 cubic yards of dirt from a 205' by 10' wide section of existing road surface and replace with 19 cubic yards of lime rock surface, Nashes' Exhibits Nos. 5 and 6, realigning the roadway slightly (to avoid the existing encroachment on the Saltiels' property) and increasing the roadbed's elevation over a 205-foot stretch by no more than four inches. Five trees are to be removed, but other trees are to be protected "by tree protection barricades." Nashes' Exhibit No. 7A. Filter fences upstream and down would contain turbidity during construction. The plan is to lay sod and plant grass seed afterwards in order to prevent erosion. Larger culverts would permit the flow of a greater volume of water at lower velocity, more closely approximating the natural regime and reducing scour or erosion downstream. Even when water levels exceeded the elevation of the existing roadbed, more water than the existing culverts can accommodate could move through the proposed replacement culverts, and at a slower velocity. At water levels above the existing grade and below the proposed, slightly higher grade, however, the four inches or less of limerock added to the roadbed would act as a (presumably somewhat porous) barrier to flows that could now move over the roadway unimpeded. The proposed improvements would have no discernible effect on water levels whenever Alford Arm overtopped the roadbed. Ted L. Biddy, the professional engineer called as a witness by the Nashes, testified that a 25-year return two-hour storm would raise water immediately upstream of the roadway, when runoff concentrated there, to levels above the existing roadway grade, assuming that the drainage basin was saturated at the time of the rainfall and that all ponds within the basin were full, but that the level of Lake Lafayette was at or below 45.3 feet NGVD. T.489. "Ordinary high water for Alford Arm is 45.7 [feet NGVD.]" T.486. On this record, it can only be a matter of speculation how often (if ever) a 25-year return, two-hour storm might be expected to occur after rainfall has saturated the ground and filled all ponds in the drainage basin without raising the lake above 45.3 feet NGVD. The wet conditions Mr. Biddy assumed already to obtain in the drainage basin at the time of the hypothetical storm seem unlikely to coincide with the low lake level assumed to occur simultaneously. Alford Arm's 100-year flood level is 51 feet NGVD, "50.25 for the 25 year flood or rainfall, and elevation 49.9 for the 10 year storm water event." T.425. In any event, flooding of the Saltiels' property attributable to the proposed raising of the roadway would last only a matter of hours every quarter of a century according to Mr. Biddy, and would represent temporary diversion of water that would otherwise have flooded their property downstream of the roadway. Even then, no house or structure on the Saltiels' property would be affected nor any part of their property not within the 100-year flood plain. At all water levels below the existing roadway grade, the overwhelmingly more frequent condition, larger culverts would prevent or diminish flooding that might otherwise reach the Saltiels' property upstream of the roadway. By impeding flows downstream, the roadway affords some solids suspended in the water an opportunity to precipitate, instead of being borne on into Alford Arm. Under certain conditions, the larger culverts proposed by the Nashes would reduce time for particulate matter to settle upstream of the roadway; the greater volume of flow through larger culverts would reduce the time water was impounded upstream. Uncontroverted expert testimony established, however, that any increase in turbidity in water reaching Alford Arm would not violate applicable standards.
Recommendation It is, accordingly, RECOMMENDED: That DER issue a dredge and fill permit to Mr. and Mrs. Nash for the project described in their application on the conditions stated in the notice of intent to issue. DONE and ENTERED this 28th day of August, 1992, in Tallahassee, Florida. ROBERT T. BENTON, II Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 28th day of August, 1992. APPENDIX Petitioners' proposed findings of fact Nos. 2 and 10 have been adopted, in substance, insofar as material. With respect to petitioners' proposed finding of fact No. 1, what knowledge petitioners are charged with is a matter of law. Petitioners' proposed findings of fact Nos. 3, 4, 7, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 and 31 pertain to subordinate matters. Petitioners' proposed findings of fact Nos. 5, 6 and 32 pertain to immaterial matters as does petitioners' proposed finding of fact No. 9. Only the dredge and fill permit DER proposes to grant the Nashes is at issue. With respect to petitioners' proposed finding of fact No. 30, the calculations of both Mr. Flatt and Mr. Biddy seem to be flawed. With respect to petitioners' proposed finding of fact No. 33, it is not clear that the proposed project would increase the flooding on the Saltiels' property significantly. Temporally de minimis, the change might amount only to relocating the flooding. With respect to petitioners' proposed finding of fact No. 34, see finding of fact No. 12. With respect to petitioners' proposed finding of fact No. 35, larger culverts will decrease the velocity of the flow through the culverts. Petitioners' proposed finding of fact No. 36 is immaterial because it does not relate to any applicable rule or statutory standard. With respect to the individual respondents' and intervenor's (applicants') proposed findings of fact Nos. 1 and 2, the application does not specify dredge and fill. The applicants' proposed findings of fact Nos. 3, 4, 5, 7, 8, 10, 17, 18, 19, 20 and 32 have been adopted, in substance, insofar as material. With respect to the applicants' proposed finding of fact No. 6, backwater flows at levels above 45.3 feet NGVD. With respect to the applicants' proposed finding of fact No. 9, the OHW is 45.7 feet NGVD. With respect to the applicants' proposed finding of fact No. 11, testimony so implied. With respect to the applicants' proposed finding of fact No. 12, Mr. Nash suffers from muscular dystrophy. The applicants' proposed findings of fact Nos. 14 and 15 pertain to subordinate matters. With respect to the applicants' proposed finding of fact No. 16, the only testimony regarding flooding concerned the critical 25-year return storm. With respect to DER's proposed findings of facts Nos. 1 and 2, the application does not specify dredge and fill. With respect to DER's proposed finding of fact No. 3, backflows begin at 45.3 feet NGVD. With respect to DER's proposed finding of fact No. 4, not all fill would be removed. With respect to DER's proposed finding of fact No. 5, testimony so implied. With respect to DER's proposed finding of fact No. 6, no statute or rule specifies a design storm. DER's proposed finding of fact No. 7 is really a conclusion of law. With respect to DER's proposed finding of fact No. 8, less settling may result in more suspended solids under some conditions. DER's proposed findings of fact Nos. 9, 10, 11 and 12 have been adopted, in substance, insofar as material. DER's proposed finding of fact No. 13 is immaterial to the merits.
