The Issue The issue for determination in this proceeding is whether Respondent, E. Speer and Associates, Inc. (the "Applicant"), should be granted a permit for the construction of a permanent docking facility pursuant to Sections 403.91-403.929, Florida Statutes, and Florida Administrative Code Chapter 17.
Findings Of Fact Whether Quantified Hydrographic Studies Are Necessary For All Marina Applications To Provide Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards Speer's Exceptions Nos. 1, 4, 5, 6, 7 and 8 in whole or in part take exception to the Hearing Officer's conclusion (stated as a finding of fact) that it is not possible to demonstrate adequate flushing without "quantifying flushing rates and pollutant dispersal rates using objective methods and appropriate hydrodynamic data." (R.O. at 20, 22-24, 47, 49-50, 54, 57-58; F.O.F. Nos. 33, 35, 38-39, 40, 43-45, 64, 66, and 69) It is clear from the tenor of the entire recommended order that the Hearing Officer believes that as a matter of law an expert's opinion is not sufficient to provide reasonable assurances that flushing will be adequate to prevent violations of water quality standards unless that opinion is based on quantified conclusions generated by objective methods and appropriate hydrodynamic data. (R.O. at 47, 49-50, 57-58) Thus, for example, the Hearing Officer opines that quantification of flushing rates and pollutant dispersal rates using objective measurements of appropriate hydrodynamic data is an essential element of the prima facie showing required to be made by the applicant. (R.O. at 47; C.O.L. No. 11) The Hearing Officer places great significance an the following excerpt from the opinion in 1800 Atlantic Developers v. Department of Environmental Reculation, 552 So.2d 946 (Fla. 1st DCA 1989), rev. den., 562 So.2d 345 (Fla. 1990): 1800 Atlantic filed 34 exceptions to the recommended order, most of which were denied in the Department's final order . . . . The final order approved and adopted most of the findings of fact and conclusions of law in the recommended order and denied the permit. The following stated rulings and reasons there for are significant to the issues on this appeal. (emphasis added) We must note at this point that there is no finding of fact in the hearing officer's recommended order that quantifies how productive the marine habitat may be in this case, and no record support for the suggestion that there would be some quantifiable diminution in the quality of the marine habitat attributable to this project [footnote omitted]. (emphasis added) Exception 23 filed by 1800 Atlantic challenged the hearing officer's finding that the project will adversely affect the conservation of fish and wildlife, fishing or recreational values, and marine productivity in the vicinity . . . The Department rejected this exception based upon the hearing officer's general statements, without any quantification whatsoever, of adverse effects upon these matters . . . (emphasis added) 1800 Atlantic, 552 So.2d at 951-952. I do not concur that 1800 Atlantic stands for the proposition that quantified hydrographic measurement of flushing is in all cases an essential element of a prima facie showing that a marina project will not cause violations of water quality standards. Notwithstanding the above noted statement of the court in 1800 Atlantic that "there is no finding of fact . . . that quantifies 'how productive the marine habitat may be' . and no record support . . . that there would be some quantifiable diminution in the quality of marine habitat attributable to [the] project," 552 So.2d 951, the court did not reject the finding that the project adversely affected the conservation of fish and wildlife, fishing or recreation values, and marine productivity. Indeed, had the court rejected the above finding due to lack of quantified findings the court would never have gone on to reach the issue of mitigation because in 1800 Atlantic mitigation could only become relevant if the applicant was unable to provide reasonable assurance that the project satisfies the public interest criteria of Section 403.918(2) (a), Florida Statutes. See Section 403.918(2)(b), Florida Statutes. I do agree that in some cases quantified hydrographic studies of flushing may be required in order to provide reasonable assurances. Thus, in Rudloe v. Dickerson Bavshore, Inc., 10 FALR 3426 (DER Case No. 87-0816, June 9, 1988), my predecessor held that a dye tracer study was necessary to provide quantitative information about dilution rates and directions on dispersion of pollutants emanating from a proposed marina site which was in "close proximity" to Class II waters approved for shellfish harvesting. 10 FALR at 3447-48. However, the need for such quantified studies must be determined on a case by case basis and is not required as a matter of law for all marinas. 5/ Far me to determine as a matter of law that experts may establish a fact only by certain types of evidence would be an unwarranted and unwise intrusion into the scientific domain of the expert. Thus, in Kralik v. Ponce Marine, Inc., 11 FALR 669, 671 (DER Final Order, Jan. 11, 1989), my predecessor held that expert testimony with regard to flushing does not lack credibility just because a hydrographic study had not been conducted. Of course, the finder of fact has the ultimate say on how much weight an expert opinion should be given if it is not based on a quantified study. Thus, whether an expert testifying on adequacy of flushing has conducted a quantifiable hydrographic study merely goes to the weight of the evidence. Kralik, 11 FALR at 671. I only conclude that a quantified hydrographic study for a proposed marina is not in all cases essential for a showing of reasonable assurances that water quality standards will not be violated. Accordingly, to the extent that the Hearing Officer's findings of fact state that a quantified hydrographic study is required in all cases as a prima facie element of a showing of reasonable assurance that a project will not violate water quality standards, I reject such statement as a mislabled and incorrect conclusion of law. Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards I read Speer's Exceptions Nos. 1, 3, 4, 5, 6, 7 and 8 in whole or in part as taking exception to the Hearing Officer's finding that under the facts of this case a quantified hydrographic study was needed in order to provide reasonable assurance that the project would not cause violations of water quality standards, and that because such a quantified hydrographic study had not been conducted, reasonable assurances had not been provided. (F.O.F. Nos. 33, 35, 38- 39, 40, 43-45, 64, 66 and 69) As noted by the Hearing Officer, the applicant's expert testimony concerning the adequacy of the flushing consisted of general statements describing visual observations of river and tidal flows which, together with past experience and knowledge of the general area of the project, formed the basis for the experts' opinions that a quantified hydrographic study was not necessary for this project. (R.O. at 22-23) Thus, far example, Mr. Charles C. Isiminger, accepted as an expert in marina design and hydrographic engineering testified that based on his knowledge of the area, its riverine and tidal flows, a hydrographic documentation was not needed to provide reasonable assurance that the project would not cause water quality violations. Mr. Isiminger also testified that any pollutants entering the water from the marina would be flushed out of the area within one tidal cycle. (Tr. at 65-66, 70, 77- 79, 93, 110, 125, 128, 134) Mr. Thomas Franklin, an environmental supervisor from the Department testified that: the hydrographic survey was not really necessary due to the location of the project being in open waters and in close vicinity to the Inlet with a large volume of tidal waters moving in this area, plus the fact that it was further enhanced by flushing due to the St. Lucie River being -- basically coming around Hell Gate point [sic] and funneling out into this estuary. (emphasis added) TR at 437. Other experts also testified that the area was well flushed and that a quantified hydrographic study was not needed in this case. (Jacqueline Kelly, Tr. at 187; John Meyer, Tr. at 319, 322, 341; Gerald Ward, Tr. at 44749) 6/ Speer asserts that the Hearing Officer's finding that a quantified hydrographic study is required in this case cannot stand in light of the unrebutted expert testimony that the marina site will be well flushed and that the rate of flushing provides reasonable assurances the water quality standards will not be violated. I have found no competent substantial evidence in the record which would support a finding that under the facts of this case a quantified hydrographic study is required. I did note that in Footnote 21 of the Recommended Order (R.O. at 20) the Hearing Officer states: Tidal range is only one of the types of data used to quantify flushing rates and pollutant dispersal rates. See TR at 78. Other appropriate data include: overall flow rates, mid tide flow, flow amplitude (the magnitude of the flow without regard to direction, i.e., speed as opposed to velocity), horizontal current distribution, downstream plume characteristics, and field verification using a dye tracer. All of this data is needed to fully describe and quantify flushing rates and pollutant dispersal rates. (citing testimony of Mr. Isiminger at Tr. 88-94) At first blush this may appear to be competent substantial evidence supporting a finding that a quantified hydrographic study is necessary in this case. However, when the testimony is read in its complete context, it is clear that Mr. Isiminger is testifying as to what is necessary to do a hydrographic study when one is needed, and is not testifying that such a study is needed in this case. (Tr. 88-94). I also note that the record contains a memo written by Dr. Kenneth Echternacht, a hydrographic engineer employed by the Department. (Tr. at 67-70) This memo was admitted without objection. (Tr. at 23) The memo states in part that "without . . . hydrographic documentation, reasonable assurance cannot be given that the project will not cause problems." (Tr. at 70; Pet. Exh. No. 10) 7/ Dr. Echternacht was not called as a witness at the hearing and the letter was not offered as evidence of the opinion of Dr. Echternacht or the Department at the time of the de novo hearing. To the contrary, the above noted testimony of Mr. Franklin and the testimony of Jacqueline D. Kelly, an environmental specialist of the Department accepted as an expert in evaluating impacts of environmental dredge and fill projects (Tr. at 187, 195; R.O. at 3), clearly establish that at the time of the de novo hearing the Department was of the opinion that further hydrographic documentation was not needed. The Hearing Officer noted that Mr. Meyer testified that the flushing is a "very, very complicated dynamic situation." (Tr. at 320). The testimony was as follows: Q. So you don't know for sure whether the currents here impact this at all or stay offshore from it? A. Oh, the currents definitelv affect it, and you do have interchange -- as I mentioned before, a very high rate of interchange on a daily basis on every tide. Q. Are you saying that the current that flows through here every day flows right through the site? A. We're dealing with two different things here. We're dealing with your currents, your general migration of waters from the estuary from the inland areas down. You're also dealing with tidal effects coming in and out, and it's a very, very complicated dynamic situation. For me to try to tell you exactly how these things work would be impossible without having a very, very long drawn-out expensive study done on the entire area, and I have not reviewed any studies like that. Tr. at 319-20 (emphasis added) When taken in its context it is clear that Mr. Meyer is testifying that there is a very high rate of exchange on a daily basis on every tide. The fact that he viewed the exact details of the flushing as very complicated in no way retracted his statement that there was a very high rate of exchange on every tide. My review of the record leads me to concur with Speer that no testimony, either on direct, cross-examination, or examination by the Hearing Officer, nor any other evidence was introduced to rebut the expert testimony presented by Speer and the Department that flushing on the site was adequate to provide reasonable assurance that water quality standards will not be violated. 8/ As a general rule, the trier of fact may not arbitrarily reject uncontroverted evidence as proof of a contested fact. Merrill Stevens Dry Dock Co. v. G. & J. Investments, 506 So.2d 30 (Fla. 3d DCA 1987), rev. den., 515 So.2d 229 (Fla. 1987); City of St. Petersburg v. Vinoy Park Hotel, 352 So.2d 149 (Fla. 2d DCA 1977); In Re: Estate of Hannon, 447 So.2d 1027 (Fla. 4th DCA 1984). This does not mean that a mere scintilla of unrebutted evidence is sufficient to establish a contested fact in an administrative hearing. At least in the context of administrative proceedings, the unrebutted evidence still must be competent substantial evidence to support a finding of fact. 9/ There is no suggestion that the Hearing Officer rejected the unrebutted testimony of the experts of Speer and the Department as not being competent substantial evidence. In fact, in the light of the testimony of Mr. Isiminger (Tr. at 65- 66), Mr. Ward ( Tr. at 447-449), Mr. Meyer (Tr. at 238- 239), and Mr. Franklin (Tr. at 345-350), it is beyond peradventure that there is competent substantial evidence to support a finding that flushing is adequate to provide reasonable assurance that the marina will not cause violations of water quality standards. It is clear from the context of the Recommended Order that the Hearing Officer believed that reasonable assurance had not been provided only because he believed that a quantified hydrographic study was required as a matter of law. Although I reject the Hearing Officer's conclusion that a quantified hydrographic study must be conducted as a matter of law for all marina applications, I must still determine whether a quantified hydrographic analysis is required under the facts of this case. In Rudloe v. Dickerson Bayshore, 10 FALR 3426 (DER Final Order, June 9, 1988) it was held that a hydrographic study was not adequate because it did not include a quantified dye tracer study. Id., 10 FALR at 3448. In Rudloe, as in this case, the marina was located in Class III waters, but near Class II waters. However, in Rudloe, the marina site was much closer to the Class II waters (approximately 1,700 feet in Rudloe (10 FAIR at 3430) as compared to approximately 8,000 feet in this case). (R.O. at 16, F.O.F. No. 26) Also, the Rudloe case is significantly different from this case in that competent substantial expert opinion was presented in Rudloe that the marina would adversely impact the Class II shellfish harvesting area. See Rudloe, 10 FALR at 3433-35, 3437-38 (testimony of DNR expert that operation of marina would result in closure of waters to the harvest of shellfish; testimony of Dr. Robert Livingston that the hydrographic drogue studies conducted were inadequate.) In this case, neither expert nor lay testimony was offered by Barringer to show that operation of the marina would result in violation of water quality standards or have any adverse impact on the Class II shellfish waters. 10/ I conclude that the facts of this case as found by the Hearing Officer are not sufficiently similar to the facts of Rudloe so as to justify holding as a matter of law a quantified hydrographic study is necessary to establish the required reasonable assurances. Since the record contains competent substantial evidence that flushing is adequate to provide reasonable assurance that the marina will not cause water quality violations, and since there is no competent substantial evidence in the record to support the Hearing Officer's contrary finding, I must accept the exception of Speer and reject the Hearing Officer's findings of fact to the contrary. In this case I note that I am not so much rejecting findings of fact as rejecting a conclusion of law. As I noted, the Hearing Officer's finding is really based on a conclusion of law which I reject. This leaves only unrebutted competent substantial evidence that there will be adequate flushing to provide reasonable assurance that the operation of the marina will not result in water quality violations. There is no rational basis to reject this unrebutted competent substantial evidence. Therefore, I must accept as proven that the applicant has provided the reasonable assurances that operation of the marina will not result in water quality violations. Merrill Stevens Dry Dock; City of St. Petersburg; Estate of Hannon; supra, Effect On Class II Waters Speer's Exceptions Nos. 7 and 8 take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the marina would not have a "negative effect" an the Class II waters of the St. Lucie Inlet and the Great Pocket. (F.O.F. No. 43) Rule 17-312.080(6)(b), Fla. Admin. Code provides: The Department also shall deny a permit for dredging and filling in any class of waters where the location of the project is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the dredging or filling will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. In this case expert testimony was presented by Speer and the Department that due to the distance of the marina site from the Class II waters (8,000 feet) the marina site was not in close proximity to the Class II waters, and due to the rapid flushing of the area, the construction and operation of the marina would neither have a negative effect nor would result in violations of water quality standards in the Class II waters of St. Lucie Inlet and the Great Pocket. (Isiminger, Tr. at 96, 126-27; Meyer, Tr. at 254-55) I find that the record contains no competent substantial evidence to rebut the evidence introduced by Speer and the Department that the marina will have no negative effect on Class II waters and will not result in violation of water quality standards in Class II waters. Accordingly, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In Re: Estate of Hannon; supra. Reasonable Assurance That Operation Of The Marina Will Not Result In Prop Dredging Or Violations Of The State Water Quality Criterion For Turbidity Speer's Exceptions Nos. 1, 2, 9-12, and 16 in whole or in part take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the boat traffic from operation of the marina would not cause prop dredging or violations of the water quality criterion for turbidity. (F.O.F. Nos. 33-34, 45, 48, 52-53, 64, and 67) 11/ On one hand, there was testimony that the depths of the marina, in combination with the size of boats allowed in the various slips, would allow for a one foot clearance from the bottom of the boats to the bottom of the marina, and that this clearance, in combination with speed limits in the marina, would provide reasonable assurance that operation of the marina would not result in prop dredging or turbidity violations. (Isiminger, Tr. at 104-107, 118; Meyer Tr. at 263-65, 299, 304- 305; Kelly, Tr. at 189-190; Ward, Tr. at 460) On the other hand, Bruce Graham, admitted as an expert in marine biology testified that: "A large boat, three feet from the bottom, I think would resuspend sediment." (Graham, Tr. at 378). The Hearing Officer, noting that when asked if one foot clearance is sufficient to prevent prop dredging and resultant turbidity violations, a Department witness, testified: I would have to say that we simply don't have enough documentation to know this for a fact. We know that a foot gives us a degree of comfort that there will not be prop wash. In certain instances -- a tug boat, for instance, you know, with huge engines, you're going to have prop wash over a much -- over a large area and with probably much more than a foot of clearance. But for the normal, typical marina a foot, as I say, gives us a degree of comfort that we have settled on. Neyer, Tr. at 264. The Hearing Officer concluded that the witnesses of Speer and the Department could not explain the reasons or efficacy of the "one foot policy" except to say that in their experience the one foot policy was adequate to prevent prop dredging and turbidity violations. (R.O. at 28 n.35)0 The Hearing Officer thus found that Speer and the Department failed to "prove up" the one foot policy -- i.e., failed to elucidate and explicate the reason for the policy. 12/ Clearly the Hearing Officer placed more weight on the testimony of Mr. Bruce Graham than that of Isiminger, Meyer, Kelly and Ward. Since I cannot say that the testimony of Graham was not competent substantial evidence, I am not at liberty to reweigh the evidence or reject the Hearing Officer's finding of fact. See, Florida Dept. of Corrections v. Bradley, 510 So.2d 1122 (Fla. 1st DCA 1987); Heifetz v. Department of Business Regulation, 475 So.2d 1277, 1281 (Fla. 1st DCA 1985); Sections 120.57(1)(b)10., and 120.68(10), Florida Statutes. Speer contends that Barringer presented no evidence that prop dredging will cause sufficient turbidity to violate the state water quality turbidity criterion of 29 NTUs. 13/ That contention misses the point. The burden is on Speer to establish by the preponderance of evidence that reasonable assurance has been provided that operation of the marina will not result in violations of the water quality criterion for turbidity. Florida Department of Transportation v. J.W.C., Co., 396 So.2d 778 (Fla. 1st DCA 1981). The Hearing Officer, as the finder of fact, concluded that Speer failed to do so. Accordingly, I reject the exception of Speer and accept the Hearing Officer's finding of fact that Speer failed to provide reasonable assurance that operation of the marina would not cause prop dredging or violations of the state water quality criterion for turbidity. Manatee Impacts and the Public Interest Test Speer's Exceptions Nos. 13 and 17 take exception to the Hearing Officer's finding that Speer failed to do a quantified study of impacts to manatees and therefore failed to provide reasonable assurance that the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat. (F.O.F. Nos. 61, 64 and 68) The Hearing Officer reasoned as follows: Instead of a traffic study, the Applicant and DER presented evidence in the form of general statements that manatees need not migrate north and south through the approach channel. According to the Applicant and DER, manatees can migrate across the project site by one of two alternative routes. They can migrate in one or two feet of water under moored boats and then under wave breaks on the north and east piers, or they can migrate in the shallow water landward of the west boundary of the project. That evidence was not persuasive and was controverted by competent, substantial, and persuasive evidence that manatees would be deterred from migrating under the project footprint by substantial obstacles in their path. Manatees migrating under the project footprint would be exposed to 86 or more moving boats with powerful engines and drafts of four to five feet in waters covering approximately 20,800 square feet. It could be argued, or course, that 86 or more boats would not be moving in and out of the marina at one time. However, it is impossible to estimate occupancy rates, length of stay, and frequency of boat trips without a traffic study. (R.O. at 35, n. 51) As Speer's exception notes, there was testimony that because of the width of the river and boat speed restrictions in the project area, there would be no adverse impacts an the manatee from the marina. (Kelly, Tr. at 162; Meyer, Tr. at 255-56, 331- 32; Isiminger, Tr. at 130) The St. Lucie/Jupiter/Hobe Sound waterways are a major travel corridor for manatees. (DER Exh. No. 4) Between 1974 and December 1990, there were ten water craft related manatee fatalities within the boating sphere of influence of the project. (DER Exh. No. 4) In order to reduce impacts on the manatees, the proposed permit contains the following specific conditions: S.C. No. 13: The permittee agrees to install and maintain a minimum of one manatee education/display on the main access pier during and after construction. S.C. No. 15: The permittee agrees that any collision with a manatee shall be reported immediately [to DNR and U.S. Fish and wildlife Service]. S.C. No. 18: The permittee shall post four (4) manatee area/slow speed signs, two of which would be spaced along the perimeter pier and two of which would be located on the outside of the marina for all boating traffic to observe within the marina facility. (DER Exh. No. 3) 14/ There was testimony that the piers, once constructed, would not impair the passage of manatees. (Isiminger, Tr. at 114- 115) On the other hand, there was some testimony that manatees may have to go around the project rather than through it. (Meyer, Tr. at 311) The existing boat traffic past the site of the project to the Inlet was "rough1y estimated" at 50 to 100 boats a day. (Meyer, Tr. at 337) The U.S. Fish and Wildlife Service determined that "while [the project] may negatively affect, it is not likely to jeopardize the continued existence of the West Indian Manatee." (Tr. at 120-21) The Hearing Officer concluded that reasonable assurance as to adverse impacts on manatees could not be provided absent a quantified traffic study. (R.O. at 35, n. 51) In Coscan Florida, Inc. v. Department of Environmental Regulation, 12 FAIR 1359 (DER Final Order March 9, 1990), the Department held that the information needed to determine a marina's impact on manatees and the necessary actions to mitigate such impacts must be decided an a case by case basis. For example, in Sheridan v. Deep Lagoon Marina, 11 FALR 4710 (DER Final Order, Aug. 24, 1989), 15/ a marina sought to expand by adding 113 new wet slips. The marina was required to develop a manatee protection plan far the surrounding portions of the Caloosahatchee River, all new slips were limited to sail boats until the manatee protection plan was implemented and enforced, and power boat occupancy was limited to 75% of the total 174 wetslips in any event. The marina also made available a wet slip for use by the Florida Marine Patrol. In this case there is evidence of significant boat related manatee fatalities in the boating sphere of influence of the proposed marina. There is also evidence of existing traffic of 50-100 boats per day past the project site. In view of the fact that this project would add 86 slips and a public fueling facility, it seems likely that that the project will significantly increase both boat traffic and the threat of manatee collisions. Accordingly, I concur with the Hearing Officer that there is competent substantial evidence to support a finding that further studies are needed to determine what, if any, additional manatee protection conditions are needed to provide reasonable assurance that manatees will not be adversely affected. I conclude that the applicant did not provide reasonable assurance that the operation of the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat, and therefore failed to provide reasonable assurance that the project is not contrary to the public interest. Therefore, I reject the exception of Speer. Cumulative and Secondary Impacts Speer's Exception No. 15 takes exception to the Hearing Officer's finding that the applicant failed to provide reasonable assurance that there will be no adverse cumulative pacts created either by the cumulative effects of the object and existing similar projects, or by secondary pacts of the project itself. (F.O.F. No. 66) 16/ Cumulative impact analysis takes into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Conservancy v. A. Vernon Allen Builder, supra; Section 403.919, Florida Statutes. Secondary impact analysis considers the impact of the project itself and of any other relevant activities that are very closely linked or causally related to the permitted project. Conservancy, 580 So.2d at 778; J.T. McCormick v. City of Jacksonville, 12 FALR 960, 980. 17/ Thus, in Conservancy the secondary impact analysis was required to consider the environmental impacts of development of 75 estate homes on an island where the development would be reasonably expected as a result of the permitted laying of a subaqueous sewer line. Similarly, in del Campo v. Department of Environmental Regulation, 452 So.2d 1004 (Fla. 1st DCA 1984), the Department was required to consider the environmental impacts of the foreseeable development of an island facilitated by the permitted building of a bridge to the island. In this case there is competent substantial evidence that there are other marinas located 1,750 feet downstream in Willoughby Creek, and 5,000 feet downstream in Manatee Pocket. (R.O. F.O.F. 31; Isiminger, Tr. at 112; Meyer, Tr. at 261) The record contains competent substantial evidence that the cumulative impact of the project and the existing marinas in Willoughby Creek and Manatee Pocket will not result in violations of state water policy. (Isiminger, Tr. at 125; Kelly, Tr. at 167) I cannot say that the testimony of Isiminger and Kelly on cumulative impacts is not competent, substantial evidence. In light of the fact that there is no competent substantial evidence to indicate that cumulative impacts would result in water quality violations, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersbur; In re: Estate of Hannon; supra. As to secondary impacts, the Hearing Officer pointed out that Speer did not introduce any evidence as to whether there would be secondary impacts to water quality as the result of further development or increased utilization of the uplands facilities. (See F.O.F. 66, n.59, R.O. at 39) Such further development or increased utilization of upland facilities is reasonably foreseeable and would be very closely linked or causally related to the building of an 86 slip marina with public fuel services. As noted above, the applicant has the burden of providing reasonable assurances as to cumulative and secondary impacts. Brown v. DER, supra; Conservancy, supra. However, neither the pleadings nor the pre-hearing stipulation raised the issue of the adequacy of the secondary impact analysis. In a case such as this where the Department's notice of intent to issue a permit has been challenged by a third party, the applicant's prima facie case need only include the application and the accompanying documentation and information relied on by the Department as the basis of its intent to issue. Florida Department of Transportation v. J.W.C., 396 So.2d 778, 788 (Fla. 1st DCA 1981). The petitioner challenging the permit must identify the areas of controversy and allege a factual basis for its contentions that the applicant did not provide the necessary reasonable assurances. J.W.C., 396 So.2d at 789. See also Woodholly Assoc. v. Department of Natural Resources, 451 So.2d 1002, 1004 (Fla. 1st DCA 1984). Since Barringer did not identify this issue and did not allege any factual basis for a contention that the secondary impact analysis was inadequate or incorrect, I may not rule on the issue in this order. Miscellaneous Exceptions To Findings of Fact Speer's Exception No. 14 takes exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the project will have no adverse impact on (1) the relative value of functions being performed by areas affected by the project, including seagrasses, shell fish, and fin-fish, and (2) recreational and commercial values in the vicinity. (F.O.F. No. 64) Speer contends that this finding is not supported in the record by competent substantial evidence and is contrary to unrebutted testimony of Ms. Kelly and Mr. Isiminger. (Kelly, Tr. at 159, 161-62, 165-67; Isiminger, Tr. at 73) I cannot say that the testimony of Isiminger and Kelly is not competent, substantial evidence, and I find no evidence in the record to rebut the testimony of Kelly and Isiminger. Therefore, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In re: Estate of Hannon; supra. Speer's Exception No. 3 takes exception to the Hearing Officer's finding that Speer failed to provide a current water quality analysis. (F.O.F. No. 35) A water quality analysis was submitted in April of 1990, shortly after the permit application was filed. (R.O. at 2, 19; F.O.F. No. 34) I find no competent substantial evidence in the record to suggest any reason for believing that the water quality has changed since April of 1990. I agree with Speer that, absent some specific reason for believing that the water quality has changed since the date of a study conducted contemporaneously with the permit application, there is no requirement to provide an updated water quality analysis. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Need For Quantified Hydrographic Study Speer's Exceptions Nos. 1, 7 and 9, in whole or in part, take exception to the Hearing Officer's conclusions of law that a quantified hydrographic study was needed to provide reasonable assurances that the operation of the marina would not result in violations of water quality standards and would would not have a negative effect on Class II waters. For the reasons stated in Parts III(1), (2) and (3) above, I accept this exception and reject the above noted conclusions of law. Introduction Of Issues Not Set Forth In Pleadings Or Pre-Hearing Stipulations Speer's Exceptions Nos. 1, 2, 3, and 5, in whole or in part, take exception to the Hearing Officer's consideration of issues of (1) the need for a quantified hydrographic study, (2) the proximity of the site to Class II waters, (3) turbidity and prop dredging, (4) cumulative impacts, and (5) the need for a quantified study on manatee impacts. For the reasons set forth in Part 111(6) above, I agree that, absent waiver, a petitioner challenging an intent to issue a permit may not raise issues at the hearing which were not raised in the pleadings or pre-hearing stipulations. However, in this case the issue of manatee impacts was raised in the pleadings, and Speer was on notice that it had the burden of proof on that issue. As to the other issues, even if I accepted far the sake of argument that they were not raised in the pleadings or pre-hearing stipulations, Speer failed to timely object to the raising of these issues at the hearing and therefore waived any objection. See Sarasota County and Midnight Pass Society v. Department of Environmental Regulation, 13 FAIR 1727 (DER Final Order, April 4, 1991). Therefore, I reject the above exceptions. Proximity To Class II Waters Speer's Exception No. 2 takes exception to the Hearing Officer's conclusion of law that Speer was required to submit a plan which demonstrated that the marina would not have a negative effect on Class II waters. (C.O.L. Nos. 12 and 13) I do not agree that where a proposed marina site is 8,000 feet from Class II waters and where the site is rapidly flushed as noted in Parts 111(1), (2) and (3) above, that the site is in close proximity with the Class II waters within the meaning of Rule 17-312.080(6), Fla. Admin. Code. Accordingly, I accept this exception and reject the above note conclusion of law. Public Interest Test Speer's Exception No. 4 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurance that the project was not contrary to the public interest. (C.O.L. Nos. 17 and 20) For the reasons set forth in Parts III(4) and (5) above, I reject this exception. Cumulative Impacts Speer's Exception No. 5 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurances that cumulative impacts would not result in water quality violations, and that such assurances could only be provided by a quantified study. For the reasons set forth in Parts III (1), (2), (3) and (6) above, I accept this exception and reject the above noted conclusions of law. Modification Of Permit Conditions Speer's Exception No. 6 takes Exception to the Hearing Officer's conclusions of law Nos. 24-34. These conclusions of law concern questions of the authority of the Hearing Officer and me to modify the conditions of the permit. I agree with Speer that since none of the parties have requested any modifications, these conclusions of law are irrelevant. 18/ Therefore I accept the exception and reject the above noted conclusions of law as irrelevant. Miscellaneous Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that Speer and the Department failed to provide reasonable assurance as to prop dredging and turbidity violations because neither Speer nor the Department sufficiently proved the basis for the one-foot clearance policy. For the reasons set forth in Part III(4) above, I reject this exception. Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that the question of whether mitigation is adequate is a question of law. I agree with the Hearing Officer and reject this exception. See 1800 Atlantic Developers v. Department of Environmental Regulation, 552 So.2d 946, 955 (Fla. 1st DCA 1989).
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that Respondent, Department of Environmental Regulation, enter a Final Order denying the application for a permit to construct the proposed project and denying the request for determination of improper purposes. RECOMMENDED in Tallahassee, Leon County, Florida, this 16th day of June, 1992. DANIEL MANRY Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399 1550 (904) 488 Filed with the Clerk of the Division of Administrative Hearings this 16th day of June, 1992.
The Issue At issue in this proceeding is whether certain development orders issued by Monroe County to Homeowners, Ocean Reef Club and Key Largo Foundation (Applicants) for a project that would ultimately result in the construction of a flushing canal in the Ocean Reef Club development on north Key Largo are consistent with the Monroe County comprehensive plan and land development regulations.
Findings Of Fact The parties Petitioner, Department of Community Affairs (Department), is the state land planning agency charged with the responsibility of administering and enforcing the provisions of Chapter 380, Florida Statutes, and all rules promulgated thereunder. Section 380.031(18) and 380.032(1), Florida Statues. Respondent, Monroe County, is a local government within the Florida Keys area of Critical State Concern designated by Section 380.0552, Florida Statutes, and is responsible for the implementation of, and the issuance of development orders that are consistent with, the Monroe County comprehensive plan and land development regulations, as approved and adopted in Chapters 9J-14 and 28-20, Florida Administrative Code. Respondents, Homeowners, Ocean Reef Club and Key Largo Foundation (Applicants), are the owners of real property in the Ocean Reef and Harbour Course subdivisions, Key Largo, Monroe County, Florida; properties that are located within that part of Monroe County designated as an area of Critical State Concern. The Applicants have sought the development orders (permits) at issue in this proceeding incident to their 8-year quest to achieve regulatory approval to initiate a project that would restore the water quality of Dispatch Creek to Class III water standards. Background The site of the proposed project, the present terminus of Dispatch Creek, is located within the Ocean Reef Club development on north Key Largo. That development is bordered on the east by the Atlantic Ocean and John Pennekamp Coral Reef State Park, on the north by Biscayne National Park, and on the west by the Biscayne Bay/Card Sound Aquatic Preserve. Currently, the development at the Ocean Reef Club includes a number of canals and boat basins, an airstrip; three 18-hole golf courses, a 174-slip marina capable of docking vessels in excess of 100 feet, and extensive residential and-commercial uses. In the mid-1970's, Dispatch Creek was a natural, albeit shallow, waterbody that was able to maintain, through natural tidal actions, water quality standards. However, in 1977 Ocean Reef Club, under permits issued by the Department of Environmental Regulation (DER) in the mid-1970's excavated the creek to new depths to create a navigable channel and extended its length beyond its natural contours. When completed, the creek was converted from a natural waterbody, that could maintain water quality standards through natural tidal action, into a dead-end system, that could not maintain such standards through natural processes along the course of its extended terminus. 1/ Over time, the water quality of Dispatch Creek from its approximate midpoint to its dead-end terminus has steadily declined. The cause of this decline is reasonably attributable to the biochemical oxygen demand placed on the creek by the continuous input of detritus from mangroves, which boarder the creek on the east and to a lesser extent on the west, and the length of the channel, coupled with the dead-end basin surrounding an island, which has assured the continued decline of water quality due to poor water circulation. As a consequence, the creek, as a habitat, has been altered from an oxygen rich system supportive of aerobic life to an oxygen poor system supportive of anaerobic life. This has evidenced itself through algae blooms, the intermittent emission of hydrogen sulfide gas, and a change in water clarity to that of a "coffee au lait" color. Currently, a significant portion of Dispatch Creek is devoid of aerobic life, and unless its condition is reversed it could not support aerobic marine organisms in the future. /2 Today, conditions in portions of Dispatch Creek fail to meet DER standards. DER regulations establish the dissolved oxygen (DO) standard to be not less than five milligrams per liter in a 24-hour period, and never less that four milligrams per liter. The DO Standard is currently violated in Dispatch Creek beginning at the mid point of the creek to its terminus. At its terminus, DO levels are chronically below one milligram per liter. Additionally, DER nutrient standards prohibit the alteration of nutrient concentrations of a body of water so as to cause an imbalance in natural populations of aquatic flora or fauna. Here, the high nutrient levels of Dispatch Creek resulting from the mangrove detritus and lack of circulation has, as heretofore noted, caused the natural aquatic flora and fauna to be replaced by anaerobic life. As a consequence of the changes in water quality that had occurred in Dispatch Creeks the Applicants have, over the course of the past eight years, sought approval from various regulatory authorities, including DER and Monroe County, of a plan to improve the water quality in Dispatch Creek. Such approval has been garnered from DER, and Monroe County's approval is at issue in this proceeding. The DER permit On February 7, 1986, the Applicants received approval from DER for a permit to construct a flushing canal from the terminus of Dispatch Creek to the Atlantic Ocean. That permit authorized the Applicants: To construct a "flushing canal" between the dead end of Dispatch Creek Waterway and the Atlantic Ocean by: excavating approximately 13,000 cubic yards to create a canal approximately 3000 ft. long by 20 ft. wide with a bottom elevation of 6 ft. Mean Low Water; placing three 6 ft. by 6 ft. by 380 ft. box culverts in the canal alignment at the basin end; placing tidal actuated flap gates on the basin end of the culverts in a manner which will allow the basin to intake water from the flushing canal on incoming tides while preventing discharge into the flushing canal on outgoing tides; placing 5 pilings across the canal at it's juncture with the Atlantic Ocean to prevent navigation in the canal; and creating a 12,900 sq. ft. mangrove mitigation area by excavating approximately 1,450 cu. yds. from a spoil area to create an area with an elevation of +1.4 Ft. NGVD which will be planted with red mangroves. DER was, in evaluating the application pending before it, charged with the duty to apply, enter alia, the criteria of the 1984 Warren Henderson Wetlands Act, Section 403.918(2), Florida Statutes, as well as Chapters 17-3 and 17-4, Florida Administrative Code. Based on DER's decision to issue its permit, it is reasonable to conclude that DER, within its permitting jurisdiction, concluded that construction of the proposed circulation channel would not lower ambient water quality, and would not significantly degrade Outstanding Florida Waters (OFW), including those of John Pennekamp Coral Reef State Park. As heretofore noted, the Department does not contend that the subject project will violate any specific criteria within DER's Chapter 403, Florida Statutes, permitting jurisdiction. The Monroe County permits On July 19, 1989, Monroe County issued to the Applicants the building permit, excavation permit, and land clearing permit (development orders), each numbered 8930001680, at issue in these proceedings. As permitted, the project proposed by the Applicants is designed to improve the water quality of Dispatch Creek, particularly in the vicinity of its dead-end terminus, and consists of two phases. Phase I contemplates the installation and operation of an aeration system for at least one year, which will extend from the dead-end terminus of Dispatch Creek toward its midpoint, as well as a water quality monitoring program, until such time as the water quality of the entire creek comports with that of adjacent Class III waters. Should the Applicants be successful in Phase I, they would then be authorized to proceed with Phase II, which would allow the construction of the flushing canal contemplated by the DER permit. As approved by Monroe County, Phase I would consist of the installation of an aeration system around the island, located at the terminus of Dispatch Creek, and in the canal, as well as the suction dredging of loose sediments in the upper reaches of Dispatch Creek. The system would consist of fifteen microporus diffuser/aerators producing approximately 5 CFM per unit, and would be anchored near the bottom to maximize the introduction of dissolved oxygen into the anaerobic water and to optimize water movement. Operation of such system, coupled with the introduction of aerobic bacteria, will shortly reduce the concentration of hydrogen sulfide dissolved in the water, reduce the concentration of ionized sulfides in solution, retard the growth and propagation of anaerobics in the benthic layer, and activate the growth and propagation of aerobics in all strata. As a consequence, over time, water clarity will improve, which will allow the penetration of sunlight into the benthos. This illumination will spawn the growth of photosynthetic bacteria, as well as phytoplankton, which will aid in the continued aerobic cleansing of the water and bottom sediments. In all, installation and operation of the aeration system, which has proven successful at other locations, should, over time, restore the waters of Dispatch Creek to Class III standards, without any adverse impacts to adjacent waters or the park. While operation of the aeration system will, over time, restore the waters of Dispatch Creek to Class III standards, the perpetual maintenance of such system would be energy intensive and expensive. for this reason, the Applicants have proposed the Phase II canal, which would maintain, through natural tidal processes, water quality standards within the creek. The canal permitted by Monroe County under Phase II is consistent in all respects with the DER permit except the Monroe County permits require that the canal be sited 20 feet landward of the alignment permitted-by DER into previously scarified uplands. So aligned, the canal would begin at the landward terminus of Dispatch Creeks run easterly within the rear lot lines of at least 15 lots within Harbour Course South subdivision, a platted subdivision, pass through a fringe of red and black mangroves fronting the ocean, and terminate approximately 100 feet seaward of the mean high water line (MHWL) within the boundaries of John Pennekamp State Park. At the point where the canal would join with Dispatch Creek, three 6 foot by 6 foot by 380 foot box culverts would!! be installed with one-way tidal activated flap gates, which would permit waters from the Atlantic to enter Dispatch Creek on a rising tide, but would preclude an exchange of waters from Dispatch Creek on a falling tide. Through such design, sufficient mix and force will be exerted within the waters of Dispatch Creek to maintain Class III water quality standards by natural circulation, and to return the habitat offered by the creek to an oxygen rich system capable of supporting aerobic life. While construction of the canal would be beneficial, by restoring the waters: of Dispatch Creek to Class III standards, it is not without cost to the environment. As aligned, the canal, although predominately within previously cleared or scarified uplands, will require excavation through several types of habitat that are either undisturbed or reestablished, including undisturbed buttonwood association, salt marsh, hardwood hammock, transitional habitat, mangroves and submerged lands, and will require the removal of approximately one-tenth of an acre of red and black mangroves, a species of special concern, as well as a number of mahogany trees, twisted air plants, prickly pear cactus and barpar cactus, which are threatened species. Its construction would likewise sever the uplands from the adjacent transitional and wetland areas that traditionally buffer, insulate and protect nearshore waters from runoff from upland areas. Construction of the canal should not, however, adversely impact any threatened or endangered animal species since the proposed alignment is currently a poor habitat for threatened or endangered species, such as the Key Largo woodrat, that may reside in the area, and there is currently no threatened or endangered animal species inhabiting the site. This is not, however, to suggest that the site would not support such species in the future, provided that existing habitat is permitted to continue its progress towards reestablishment. To mitigate the loss of habitat types, the Monroe County permit provides: The agreed mitigation for the loss of all rare and/or endangered habitat types located within the area impacted by the dredging shall be carried out prior to initiation of the dredge project. This shall be based on existing vegetation surveys and an assessment of species currently located within the confines of the project area. Prior to initiation of any dredge activity, a formal inventory of the project site shall be made and a one-to-one replacement program (baked on species rarity or level of endangerment) shall be established and agreed upon. Such an agreement will include defining an appropriate site and the number and type of trees, as well as a maintenance plan for the agreed upon area. Additionally, the DER permit addresses the loss of mangroves, by requiring the establishment of a 12,900 square foot mangrove mitigation area. Under the facts of this case, the mitigation proposed would, assuming the propriety of such development under the Monroe County comprehensive plan and land development regulations, address the loss of habitat types occasioned by development of the proposed canal. To assure that water quality within Dispatch Creek comports with Class III standards before the canal is dug, and that the creek maintains such standards following construction, the Monroe County permits establish a water quality monitoring program. During the first year, samples will be taken and tests performed on a weekly basis for pH, DO, turbidity, Secchi Disc, temperature, and sulfite; on a biweekly basis for total bacterial count and composition; on a monthly basis for total nitrogen and phosphate; on a quarterly basis for: macro-invertebrates and macrophytes; and on a semiannual basis for heavy metals and pesticides. During the second yearn biweekly testing will be done for DO, temperature, hydrogen sulfide, turbidity and Secchi Disc; quarterly testing for total nitrogen and phosphate, macro- invertebrates, and macrophytes; and, annual testing for heavy metals and pesticides. After the second year, monthly tests will be done for DO, temperature, hydrogen sulfide, turbidity, and Secci Disc; quarterly tests for total nitrogen and phosphate, as well as macro- invertebrates; and annual tests for heavy metals and pesticides. Should the water quality of the creek fail to maintain Class III standards following construction of the canal, the Monroe County permit contains the following special condition: The water quality monitoring program shall be maintained to assess the quality of water in Dispatch Creek subsequent to the dredge project completion. If at any time the water quality fails to meet the standards established by this permit, the one way flushing valve shall be closed by the applicant, and in applicant's failure to do so, by the County. The applicant assumes all costs of closing said valve, whether closed by applicant or the County. Aeration, aid/or other means at the discretion of the applicant, shall be utilized to reestablish quality. The valve shall not be reopened until the water quality standard is met. The purpose of the foregoing condition, as well as the requirement that the waters of Dispatch Creek meet Class III standards before the canal can be dug, is to assure that operation of the canal will not lower ambient water quality within the Outstanding Florida Waters of John Pennekamp Coral Reef State Park, and thereby protect the park from any adverse impacts associated with the improved circulation of the creek. John Pennekamp Coral Reef State Park is a unique and world-renowned resource, attracting millions of visitors each year. At least fifty percent of the activities engaged in by visitors to the park are water-related, including fishing, observational diving and boating. Any degradation of the ambient quality of those waters would be contrary to DER's rules promulgated under Chapter 403, Florida Statutes, and could adversely impact the natural biota of the park, with a corresponding reduction in the number of visitors to the park and revenues contributed by those visitors to the local economy. Here, the proof demonstrates, consistent with DER's prior permitting, that the subject project, built as proposed, would not lower the ambient water quality of adjacent waters through the discharge of pollutants, and therefore would not adversely affect the park. If anything, the Monroe County permits, with one exception to be discussed infra, offer stronger assurances than the DER permit that adverse impacts will not occur. Notably, under such permits the Applicants must first bring the water quality of the Creek up to Class III standards before the canal can be dug. If the Applicants are ssuccessful at that phase of the project, there will not be excessive nutrient loading within the creek, and the detritus that may thereafter be removed from the creek by improved circulation would not adversely affect water quality or the park. Currently, there are no heavy metals in the sediments or water column of the creek which are at levels above those found naturally, and no pesticides or toxic organics. In sum, there is no basis to conclude, based on the record, that-there is any substance within the waters or sediments of Dispatch Creek that would, upon the waters achieving Class III standards, lower the amient quality of adjacent waters or adversely impact the park. /4 Ostensibly, as an added measure of protection to adjacent waters, the Monroe County permits contain a condition, with which the Applicants concur, that should the waters of Dispatch Creek fail to maintain Class III standards following construction of the canal, the one-way tidal actuated flap gates will be closed. That condition, a noted supra, provides: If at any time the water quality [of the creek] fails to meet the standards established by this permit, the one way flushing valve shall be closed by the applicant, and in the applicant's failure to do so, by the County. The applicant assumes all costs of closing by applicant or the County. Aeration, and/or other means at the discretion of the applicant, shall be utilized to reestablish quality. The valve shall not be reopened until the water quality standards is met. The foregoing condition presumes to address the possibility that should the proposed project fail to function as expected by the experts, as did the current Dispatch Creek fail to function as expected, that such failure will no result in an adverse impact to adjacent waters or the park. In this regard, it is worthy of note that DER's approval of the extension of Dispatch Creek to create a 7,200 foot dead-end canal in the mid-flush the pollutants from the canal into the park. The Applicants presented persuasive testimony, however, through their 1970's was, based on current knowledge, an error, and that today no dead-end system would be approved in excess of soon feet. Monroe County's condition, while preventing the discharge of degraded waters from Dispatch Creek to the park upon closure of the one way flushing valves, fails to address, however, the adverse impacts that could result from its closure. By closure of the valves, the flushing canal would be instantly converted into a 3,000-foot dead-end canal, and would suffer the same water quality problems as similar systems, with probable adverse effects to adjacent waters and the park. Accordingly, so as not to compound the existing error occasion by the extension of Dispatch Creek in the mid-1970's, prudence would dictate a proviso that, if the valves are shut, appropriate monitoring will occur within the waters of the flushing canal to detect any significant degradation of water quality, and that should such degradation pose a threat to adjacent waters or the park, that the Applicants be required, at their expense, to restore promptly the water quality within the flushing canal to Class III standards or restore the area to its present condition. Consistency of the proposed project with the Monroe County comprehensive plan and land development regulations Lack of plat approval As heretofore noted, the proposed canal would begin at the landward terminus of Dispatch Creek and run easterly within the rear lot lines of at least 15 lots in Harbour Course South subdivision, a platted subdivision, before it passed through fringing mangroves and terminated in the Atlantic Ocean. Currently, the final recorded plats of Harbour Course South subdivision do not reflect the proposed canal, as mandated by Section 177.091(15), Florida Statutes, and the Applicants have not sought to amend the plat to include the proposed canal. Pertinent to this case, the Monroe County Code (MCC), the land development regulations, /5 provides: Sec. 9.5-1. Purpose. It is the purpose of this chapter, the Land Development Regulations, to establish the standards, regulations, and procedures for review and approval of all proposed development of property in unincorporated Monroe County, and to provide a development review process what will be comprehensive, consistent and efficient in the implementation of the goals, policies and standards of the comprehensive plan . . . Sec. 9.5-2. Applicability. General Applicability: The provisions of this chapter shall apply to all land in unincorporated Monroe County. All development of whatever type and character, whether permitted as of right or as a conditional use, shall comply with the development standards and the environmental design criteria set forth in article VII hereof. No development shall be undertaken without prior approval and issuance of a development permit under the provisions of this chapter and other applicable laws and regulations. Sec. 9.5-81. Plat approval and recording required. * * * No building permit, 6/ except for single family detached dwellings and accessory uses thereto, shall be issued for the construction of any building, structure or improvement unless a final plat has been approved in accordance with the provisions of this division and recorded for the lot on which the construction is proposed. * * * (e) If a plat has been previously approved and recorded, technical or minor changes to the plat may be approved by the director of planning. All other changes shall be considered in accordance with the provisions of this Division. Sec. 9.5-94. Amendment of a recorded final plat. An amendment of a recorded final plat or portion thereof shall be accomplished in the same manner as for approval of the plat. Here, the subject permits were issued contrary to the foregoing provisions of the MCC because there was no final plat of record approving the canal as to each affected lot. While the Applicants offered proof, if credited, that the existing plat could be amended to include the canal as a "minor change" upon approval of the Director of Planning, it is noteworthy that no such approval has been obtained. More importantly, it is found that a change in the existing plat to include the canal would not constitute a "technical or minor change," and that formal amendment of the plat would be required. 7/ The provision of the MCC dealing with plat approval, provide a comprehensive scheme to assure, among other things, than the proposed plat is consistent with the purposes, goals and objectives of the comprehensive plan, the development regulations, and state laws, as well as affording an opportunity for public input. Of import here, the MCCs provide: Sec. 9.5-82. General Standards for Plat Approval. No preliminary or final plat shall be approved unless the plat is consistant with the purposes, goals and objectives of this plan, this chapter, applicable provisions of state law, the provisions governing the development of land set forth in article VII, and the procedures set forth in this article. Sec. 9.5-83. Preliminary Plat Approval. Generally. All applicants for approval of a plat involving five (5) or more lots shall submit a preliminary plat for approval in accordance with the provisions of this section. Application. An application for preliminary approval shall be submitted to the development review coordinator in accordance with the provisions of this section, accompanied by a nonrefundable fee as established from time to time by the board of county commissioners. The application shall contain the information required on a form provided by the director of planning. Staff Review. After a determination that the application for preliminary plat approval is complete under the provisions of section 9.5-44, the development review coordinator shall submit the application to the development review committee, which shall prepare a recommendation and report for the commission. Public Hearing and Action by the Planning Commission. The planning commission shall conduct a public hearing on an application for preliminary plat approval of a subdivision involving five (5) or more lots, in accordance with the requirements of sections 9.5-46 and 9.5-47. The commission shall review such applications, the recommendation of the development review committee, and the testimony at the public hearing, and shall recommend granting preliminary plat approval, granting approval subject to specified conditions, or denying the application at its next meeting following submittal of the report and recommendation of the development review committee. Effect of Approval of Preliminary Plat. Approval of a preliminary plat shall not constitute approval of a final plat or permission to proceed with development. Such approval shall constitute only authorization to proceed with the preparation of such documents as are required by the director of planning for a final plat. Sec. 9.5-84. Final Plat Approval. Generally. All applicants for approval of a plat shall submit a final plat for approval in accordance With the provisions of this section. Application. It shall be the responsibility of the developer to complete, have in final form, and submit to the development review coordinator for final processing the final plat, along with all final construction plans, required documents, exhibits, legal instruments to guarantee performance, certificates properly executed by all required agencies and parties as required in this article, and the recording fee, and any other documents or information as are required by the director of planning. After receipt of a complete application for final plat approval, as determined in accordance with section 9.5-44, development review coordinator shall submit the application and accompanying documents to the development review committee. Review and action by Development Review Committee. The development review committee shall review all applications for final plat approval. b. For a final plat for subdivision involving five (5) or more lots, if the plat conforms to the approved preliminary plate and the substantive and procedural requirements of this chapter, at its next regular meeting or as soon as practical after receipt of a complete application, the development reviews committee shall recommend to the planning commission approval of the final plat or approval with conditions. If the committee finds that the plant does not substantially conform to the approved preliminary plat or the substantive and procedural requirements of these regulations, the committee shall recommend denial, specifying the area(s) of nonconformity. Review and Action by the Planning Commission. The planning commission shall review all applications far final plat approval involving five (5) or more lots and the recommendation of the development review committee. If the commission finds that the final plat conforms to the approved preliminary plat and the substantive and procedural requirements of this chapter, the commission shall recommend to the board of county commissioners approval of the final plat, or approval with specified conditions, and shall submit a report and written findings in accordance with section 9.5-47. Public Hearing by the Board of Country Commissioners. The board off county commissioners shall conduct a public hearing on all applications for final plat approval involving five (5) or more lots in accordance with the procedures of section 9.5-46C. Action by the Board of County Commissioners. For proposed subdivisions involving five (5) or more lots the board of county commissioners shall review the application, the recommendations of the development review committee and the planning commission, and the testimony at the public hearing, and shall grant final plat approval, grant approval subject to specified conditions, or deny the application, in accordance with the provisions of section 9.5-47. Sec. 9.5-90.Maintenance of Private Improvements. If any plat of subdivision contains streets, easements, or other improvements to be retained for private use, the final plat for recordation shall indicate to the satisfaction of the director of planning and the county attorney the method or entity by which maintenance of the private improvements shall be performed. As a consequence of Monroe County's failure to comply with the provisions of its regulations which require final plat approval before a building permit may be issued, there has been no review by the Development Review Committee, no public hearing conducted by the Planning Commission, no recommendation of the Planning Commission, and no public hearing before the County Commissioners on the propriety of amending the subject plat to permit the proposed construction, or a resolution, through the plat approval process, as to whether the proposed canal is consistent with, inter alia, the purposes, goals, and objectives of the Monroe County comprehensive plan, as mandated by section 9.5-82(a), MCC. As importantly, where, as here, the proposed canal is to be retained for private use, there is no indication on the recorded plat, 4s required by MCC 9.5-90, of the method or entity by which maintenance of the canal shall be performed. Notably, the property through which the canal will be constructed is not owned by any of the Applicants but, rather, by Driscoll Properties , with whom the Applicants state they have an agreement to permit construction. 8/ Open space requirements and environmental design criteria Pertinent to this case, the MCC further provides: Sec. 9.5-3. Rules of construction. In the construction of the language of this chapter, the rules set out in this section shall be observed unless such construction would be inconsistent with the manifest intent of the board of commissioners as expressed in the Monroe County Comprehensive Plan or an element or portion thereof, adopted pursuant to chapters 163 and 380, Florida Statutes (1985). The rules of construction and definitions set out herein shall not be applied to any section of these regulations which shall contain any express provisions excluding such construction, or where the subject matter or context of such section is repugnant thereto. (a) Generally: All provisions, term , phrases and expressions contained in this chapter shall be liberally construed in order that the true intent and meaning of the board of county commissioners may be fully carried out. Terms used in this chapter, unless otherwise specially provided, shall have the meanings prescribed by the statutes of this state for the same terms. In the interpretation and application of any provision of this chapter, it shall be held to be the minimum requirement adopted for the promotion of the public health, safety, comfort, convenience and general welfare. Where any provision of this chapter imposes greater restrictions upon the subject matter than a general provision imposed by the Monroe County Code or another provision of this chapter, the provision imposing the greater restriction or regulation shall be deemed to be controlling . . (Emphasis added) Sec. 9-804 (MCLDR) Open space requirements. No land shall be developed, used or occupied such that the amount of open space on the parcel proposed for development is less than the following ratios, nor shall open space be cleared or otherwise disturbed including ground cover, understory, mid-story, and canopy vegetation. All such required areas shall be maintained in their natural condition. The amount of open space required on any parcel for development shall be determined according to each land type and no development activity within any individual land type shall exceed the open space ratio for that land type.

Environmental design criteria. No land, as designated on the existing conditions map and analyzed in accordance with the standards in sections 9.5-339 and 9.5-340, shall be developed, used ~re occupied except in accordance with the following criteria unless the county biologist recommends an authorized deviation from the following criteria in order to better serve the purpose and objectives of the plan and the director of planning or planning commission approves the recommendation as a minor or major conditional use. No recommendation for an authorized deviation from these environmental design criteria shall be made unless the county biologist makes written findings of fact and conclusions of biological opinion which substantiate the need and/or benefits to be derived from the authorized deviation. (m) Mangroves and Submerged Lands: Except as provided in subsection (3), only piers, docks, utility pilings and walkways shall be permitted on submerged lands and mangroves; All structures on any submerged lands and mangroves shall be designed, located and constructed such that: All structures shall be constructed on pilings or other supports; Bulkheads and seawall shall be permitted only to stabilize disturbed shorelines or to replace deteriorated existing bulkheads and seawalls; No structure shall be located on submerged land which is vegetated with sea grasses except as is necessary to reach waters at least four (4) feet below mean low level for docking facilities. (Emphasis added) From the foregoing regulations it is apparent that Monroe County has accorded mangroves the highest of protections. The regulations mandate a 100 percent open space ratio in such areas, and preclude any clearing or other disturbance of such areas. The only exception provided by the regulators, absent approval of an application for a minor or major conditional use, is for the construction of piers, docks, utility pilings and walkways, and then only when such structures are constructed on pilings or other supports to minimize their impact. Here, the proposed development, "permitted as of right" and not as a minor or major conditional use, fails to comply with the Monroe County land development regulations because it will result in the elimination of an existing mangrove community. In addition to the environmental design criteria established for mangroves by section 9.5-345, discussed supra, that section likewise establishes-specific performance standards for the development of any parcel (lot) depending on the habitat type, and where mixed habitat is encountered, requires that development occur on the least sensitive portions of the parcel. Here, while the Applicants did address the habitat types encountered along the canal alignment, the record fails to address the habitat types encountered on each of the platted lots through which the canal will run. Consequently, the Applicants failed to demonstrate that development of those lots, by construction of a canal within their rear boundary, would be consistent with the open space ratios mandated by section 9-804, MCLDR, or the environmental design criteria mandated by section 9.5-345, MCC. C. The Monroe County land development regulations further and implement the Monroe County comprehensive plan. The foregoing land development regulations were adopted by Monroe County, as well as approved by the Department and adopted by the Administrations Commission, to further and implement the standards, objectives and policies of the Monroe County comprehensive plan. That plan evidences a strong commitment to the protection, maintenance, and improvement of the Florida Keys environment. In this regard, the comprehensive plan provides: Sec. 2-104. Nearshore Waters The Florida Keys are dependent nearshore water quality for their environmental and economic integrity. The heart of the Florida Keys economy, the means by which Monroe County exists as a civil and social institution, is based on its unique, oceanic character. If nearshore water quality is not maintained, then the quality of life and the economy of Monroe County will be directly and immediately impacted. OBJECTIVES 1. To protect, maintain and, where appropriate, improve the quality of nearshore waters in Monroe County. POLICIES 1. To prohibit land uses that directly or indirectly degrade nearshore water quality. To prohibit the development of water dependent facilities, including marinas, at locations that would involve significant of the biological character of submerged lands. To limit the location of water- dependent facilities at locations that will not have a significant adverse impact on offshore resources of particular importance. For the purposes of this policy, offshore resources of particular importance shall mean hard coral bottoms, habitats of state or federal threatened and endangered species, shallow water areas with natural marine communities with depths at mean low tide of legs than four (4) feet, and all designated Aquatic Preserves under Ch. 258.39 et seq. the Florida Statutes. To limit the location of docking facilities to areas which have adequate circulation and tidal flushing. To protect wetland and transitional areas that serve to buffer, insulate and protect nearshore waters from run- off from upland areas. To prohibit the discharge of any pollutant directly or indirectly into nearshore waters. For the purposes of this policy, indirect discharge into nearshore waters shall include surface runoff, surface spreading or well injection of any effluent that does not meet state or federal standards for point and non-point discharges. To monitor nearshore water quality to ensure that growth and envelopment is not degrading nearshore water quality. To encourage the rehabilitation of canals and other water bodies where water quality has deteriorated. Sec. 2-105. Wetlands and Associated Systems Wetlands are an essential element of the Florida Keys and they play several vital roles. Wetlands serve as principal habitats for a wide variety of plants and animals, including juvenile forms of several commercially-exploited species of seafood. In addition, wetland plants play an important role in pollution control through nutrient uptake, and in primary production control through nutrient uptake, and in primary production for food webs. Wetland plants also serve as important natural buffers to the onslaught of storm-driven winds and water. OBJECTIVE To protect and maintain the functional integrity of wetlands and associated transitional areas within the Florida Keys. POLICIES To prohibit the destruction, disturbance or modification of any wetland or associated transition area, except where it can be demonstrated that the functional integrity of a wetland or associated transitional area will not be significantly adversely affected by such disturbance or modification. Marine Resources The great value attributed to Monroe County's marine resources is due to their crucial role in the local economy, and in providing a wide range of natural amenities and services. Health and integrity of the marine system is a fundamental prerequisite if these resources are to continue to provide social, economic, and environmental benefits that we have at times taken for granted. Mangroves, seagrasses, and coral reefs, all of which are susceptible to pollution and dredging, are extremely important in providing food and shelter for myriad forms of marine life, providing storm protection, and maintaining water quality. If uses and activities such as dredge and fill, destruction of natural vegetation, use of pesticides and fertilizers, improper sewage and solid waste disposal continue indiscriminately and uncontrolled; the ability of the marine system to function effectively will deteriorate, thereby resulting in the loss of many natural services and socioeconomic benefits to society. Therefore, it is imperative that such uses and activities be carefully regulated so as to insure conservation and protection of resources and long-term maintenance of their productivity. Marine Resources Management Policies Recognizing the crucial role that the marine environment plays in the economy, the protection, conservation, and management of marine resources will be viewed as an issue requiring the County's utmost attention. In an effort to protect and conserve marine resources, emphasis will be placed on protecting the entire marine ecosystem. To this end, maintenance of water quality; protection of marine flora and fauna, including shoreline vegetation; and preservation of coral reefs will be regarded as being absolutely essential to maintaining the integrity of the marine system. * * * Land and water activities which are incompatible with the preservation of marine resources because of their potential adverse effects will be prohibited, restricted, or carefully regulated depending upon the nature of activity and the extent of potential impact. * * * 3.2. Dredging and/or filling associated with maintenance or necessary water- dependent public projects shall be minimized and carefully managed to prevent unnecessary adverse environmental impact. The County will develop and enforce stringent development regulations to minimize water pollution from point and non-point sources in an effort to: improve and maintain quality of coastal waters. . Marine grass beds, mangrove communities, and associated shoreline vegetation will be preserved to the fullest extent possible. Removal of vegetation or modification of natural patters of tidal flow and nutrient input, cycling and export should be considered only in the case of overriding public interest. The County will encourage creation and restoration of marine grass beds, and mangrove communities in areas which could support such growth and could potentially enhance the environmental quality. As far as possible, natural patterns of gradual and dispersed runoff will be maintained. Land and water activity in the vicinity of stress areas (coral, grass bed, and inshore water quality) as identified and illustrated in the Florida Keys Coastal Zone Management Study and as may be discovered during any future study will be carefully controlled and regulated in an effort to arrest further deterioration. Research and study directed toward alleviating the stresses and restoring their condition to natural healthy state will be encouraged arid supported. Marine Resources Areas of Particular Concern Site-specific Designations Lignumvitae Key Aquatic Preserve. * * * Management Policies: B. Development activity on Upper and Lower Matecumbe Keys, including dredging and filling will be prohibited so as not to degrade the waters of the Preserve. * * * 3. John Pennekamp Coral Reef State Park and Key Largo Coral Reef Marine Sanctuary. Management Policies: * * * B. Development activity on Key Largo, including dredging and filling, urban runoff water, and the use of septic tanks will be controlled and regulated in order to minimize stresses which result in cater quality deterioration. Generic Designations All marine grass beds in waters off the Florida Keys. All patch reef coral and other reef formations found in the surrounding waters off the Keys. All shore-fringing mangrove and associated vegetation extending up to 50 feet laterally upland from the landward limit of the shoreline mangrove. Management Policies A. These biotic communities will be preserved to the fullest extent possible. Natural Vegetative Resources The diverse and often unique plant associations of the Florida Keys are a vital element of Monroe County's natural system and economic structure. The natural functions performed by these plant communities with1 regard to marine resources, unique and endangered wildlife, shoreline stabilization, filtering of urban runoff and scenic value make them vital elements in maintainance of the urban structure and attractions for the tourist base of Monroe County's economy. Natural Vegetation Management Policies In recognizing the need to preserve as much natural vegetation as possible, the County will direct its land use and development regulations; to minimize destruction of natural vegetation and modification of landscape. Guidelines and performance standards designed to protect natural vegetation from development will be developed and enforced. Clearing of native vegetation for development will be controlled. 3. Regulations controlling development in areas characterized primarily by wetland vegetative species such as mangrove and associated vegetation will emphasize preservation of natural vegetation to the maximum degree possible. 8. The existing County ordinances designed to protect and conserve natural vegetation will be strictly interpreted, rigidly enforced, and/or amended when necessary. Consistent with the Monroe County comprehensive plan, the Monroe County land development regulations further the standards, policies and objectives of the plan to protect, maintain and improve the Florida Keys environment. In this regard, the provisions of the regulations requiring final plat approval before a development order may issued provide assurance that the proposed activity will be -consistent with the comprehensive plan, the land development regulations, and applicable provisions of state law. Likewise, pertinent to this case, the provisions of section 9-864, MCLDR, regarding open space requirements, and section 9.5-345, regarding environmental design criteria, further the plan's policy to minimize the destruction of natural vegetation and modification of landscape, and to preserve to the maximum degree possible areas characterized primarily by wetland vegetation, such as mangroves and associated vegetation, and to permit such removal only in cases of overriding public interest. Here, while it cannot be concluded, as advocated by the Department, that the Monroe County comprehensive plan and land development regulations prohibit, under any circumstances, construction of the subject canal, it must be concluded, at this stage, that construction of the canal has not been demonstrated to be consistent with the plan and regulations. To be consistent, the Applicants would have to secure final plat approval for the canal, through the plat amendment process; a minor or major conditional use approval, as appropriate, as mandated by, inter alia, section 9 .5-345, MCC, for destruction of the mangrove community; and demonstrate that excavation of the canal on each of the platted lots would be consistent with the open space ratios of section 9- 804, MCLDR, and the environmental design criteria of section 9.5-34, MCC, or secure a conditional use as required by section 9.5-34-5, MCC. Amendment to the application post hearing In their proposed recommended order, submitted post hearing, the Applicants propose that the hearing officer recommend that, as a condition, the proposed canal terminate at the line of mean high water instead of extending approximately 100 feet into the boundaries of John Pennekamp State Park. The ostensible reason for the Applicants' request is their desire to eliminate the need for seeking approval from the Department of Natural Resources for intrusion into the boundaries of the park, and thereby shorten the time needed to secure all governmental approvals. While the Applicants did elicit testimony at hearing, albeit on rebuttal, that termination of the canal at the mean high water line would not significantly affect its performance as a flushing canal due to the extreme porosity of the caprock, the proof is not persuasive that the subject permits should be so limited or conditioned. Notably, the opinion that was offered in this regard was that of an expert hydrographic engineer who directed his remarks solely from a hydrographic viewpoint. The Applicants offered no testimony or other proof that would address the potential impacts, in any, that might occur to, inter alia, water quality or the biota, should the canal be terminated or closed in such a fashion. Under the circumstances, the Applicants failed to persuasively demonstrate that such amendment or condition is appropriate. This finding is not, however, preclusive of their applying for such modification to Monroe County.
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 sustaining Monroe County's issuance of the subject permits in so far as they relate to Phase I of the proposed project, and reversing Monroe County's decision to issue the subject permits in so far as they relate to Phase II of the proposed project. It is further recommended that such final order specify those items set forth in paragraph 4, Conclusions of Law, as the changes necessary that would make the Applicants' proposal eligible to receive the requested permits for Phase II of their proposal. DONE AND ENTERED in Tallahassee, Leon County, Florida, this 19th day of October 1990. WILLIAM J. KENDRICK 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 19th day of October 1990.
The Issue The issue presented here concerns the entitlement of the Petitioner, Turtle Lake Land Trust, to be permitted by the Respondent, State of Florida, Department of Environmental Regulation, to dredge approximately 600,000 cubic yards of material in the area known as Turtle Lake, which is located near Jackson street and Fairfield Drive, Pensacola, Florida. The purpose of this project is to create a manmade lake. The dredged material world be placed on the lake shore.
Findings Of Fact On May 9, 1979, the Respondent, State of Florida, Department of Environmental Regulation, received an environmental permit application from the Petitioner, Turtle Lake Land Trust. The details of that permit application were contained in a form provided by the Department together with attachments to that form. A copy of this permit application may be found as the Respondent's Exhibit No. 2 admitted into evidence. By this application, Turtle Lake requested that it be allowed to dredge approximately 600,000 cubic yards of material in an area known as Turtle Lake, which is located near Jackson Street and Fairfield Drive, Pensacola, Florida. The purpose of the excavation was to establish a manmade lake approximately twelve (12) feet in depth in an area which is a cypress swamp and subject to periodic inundation by water. The materials removed from the dredging would be deposited on the shores of the lake, effectively raising the ground elevation at lakeside. The dredging would intersect the groundwater on the project site. The project is part of an overall development which would involve construction of residential housing and commercial facilities in the vicinity of the lake, with the lake to be used for fishing, sailing and other water recreation. The proposal of the Petitioner was reviewed by the Department and certain timely additional requests were made from the Department to the applicant to provide information necessary to evaluate the request for permit. The exhibits dealing with the request for additional information and responses to those requests may be found as Respondent's Exhibits 3, 5, 8, 9, 10 and 11 admitted into evidence. The Department solicited comments from the Florida Game and Freshwater Fish Commission on this subject and the comments were provided by correspondence from the Executive Director of the Commission. These comments may be found in Respondent's Exhibit No. 6 admitted into evidence, which is a copy of those remarks. The Department of Environmental Regulation, in keeping with the provision Subsection 253.124(3), Florida Statutes, performed a biological survey of the project site and submitted it to the Board of County Commissioners of Escambia County, Florida, for the Board's action. A copy of the survey may be found as Respondent's Exhibit No. 7 admitted into evidence. The Escambia County Board of County Commissioners, by Resolution dated October 11, 1979, approved the project subject to action by the Respondent and the United States Corps of Engineers. A copy of this Resolution may be found as the Respondent's Exhibit No. 12 admitted into evidence. Upon consideration of the permit request, the Department of Environmental Regulation notified the applicant of its intent to deny the permit request. This Letter of Intent to Deny was issued on January 31, 1980, and a copy of it may be found as Respondent's Exhibit No. 13 admitted into evidence. This matter has been presented for consideration before the State of Florida, Division of Administrative Hearings, upon referral by the Respondent of the original Petition and has been heard after opportunity for and amendment to that Petition. The hearing was conducted on September 23, 1980, as scheduled, in keeping with the provisions of Subsection 120.57(1), Florida Statutes. The project site is located in a cypress swamp which has also been referred to as a cypress head. The southern boundary of the project site east of Fairfield Drive has an impoundment area which is fringed by pine trees and other upland species, to include gallberry, southern brackin, blackberry and oak. There is within this area aquatic vegetation dominated by Eleocharis sp. and fragrant waterlily (nymphaea odorata). The cypress head itself, which is bounded on the west by Fairfield Drive, consists of cypress, blackgum, sweetbay and cinnamon fern, fragrant waterlily and pickerel weed (pontederia lanceolata). Within the zone of the cypress head standing water may be found, the dimensions and depths of which were not established at the hearing in sufficient detail to allow further comment in these findings. Fairfield Drive serves to contain the water found in the Turtle Lake swamp on the eastern side of that roadway; however, there is an exit from the cypress head under Fairfield Drive by a series of three 24-inch culverts which connect the manmade ditches. These ditches flow into Bayou Marcus and Bayou Marcus Creek and eventually into Perdido Bay. This water connection is a direct connection and Bayou Marcus, Bayou Marcus Creek and Perdido Bay are waters of the State. Immediately adjacent to Fairfield Drive east of that roadway in the vicinity the culverts water may be found standing and could be navigated and this may be seen by Respondent's Composite Exhibit No. 14. This water which although subject to navigation wad not identified sufficiently at the hearing to establish its length and breadth. The depth was two to three feet. This water adjacent to Fairfield Drive is not within that area of the proposed excavation. At present, the storm water runoff from the Forte subdivision located to the north and east of the project site, enters the cypress head swamp and at times of periodic inundation, this storm water runoff arrives at the area of the culverts into the ditch system and into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. The oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which make up the storm water constituents are somewhat filtered by the cypress head swamp as it now exists, prior to the entry of those materials into the culvert area adjacent to Fairfield Drive and from there into the transport mechanism constituted of the ditches, bayou, creek and bay. If the project is built out, the dredging will remove those flora mentioned herein and the fauna which inhabit this swamp and will remove the cypress head from future use by the fauna which normally inhabit this form of environment. It would also take away the natural filtration to be provided by the swamp in the way of removing undesirable storm water constituents from the residential runoff in Forte subdivision and the proposed development associated with the lake construction. The removal of the swamp would destroy the capacity to convert raw nutrients into usable sources of food for indigenous dawn stream organisms. As can be seen in the Petitioner's Exhibit No. 1, the existing water table at the site is approximately 23 feet and ordinary highwater elevation has been measured at 24 feet with an existing grade of 21 feet. If the lake were excavated, the lake would show a water table with an elevation of 20 feet. The berm or dykes around the lake would have an elevation of 24 feet. Storm water from the current subdivision and the residential and commercial build-out associated with the project in question would be carried through underground storm water piping into four holding areas which have been referred to by the applicant as drainage corridors and retention area. These areas are separated from the lake by siltation screens and will serve the function of filtering out some storm water constituents which are solid particulates. The constituents which have been dissolved will flow through the siltation screen devices and into the lake proper. When the lake rises to a depth of 23 feet, the excess water will he transported through a proposed ditch into the area of the three culverts under Fairfield Drive and via those manmade conveyances into Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Those storm water constituents such as oils and greases, fertilizers, pesticides, nutrients and other forms of pollutants which have not settled or been filtered will be transported through this system and deposited into waters of the State. In this connection, the drainage corridor and retention areas are not designed for long-term retention; they are primarily for short-term detention, depending on the amount of loading from the storm water runoff. The only pre-treatment associated with the storm water runoff is that filtration that occurs in the drainage corridor and retention area. (There was some discussion of possible gravel filters in conjunction with the drainage corridor and retention area but they were not part of the plan submitted to the Department in the process of project review.) In addition to the introduction of the storm water contaminants into the waters adjacent to Fairfield Drive at the area of the culverts and the bayou, creek and bay, these contaminants will be introduced into the ground water in the lake proper Although some increase in retention of storm water runoff may be expected, if the project were built, there would be a significant increase in the introduction of dissolved contaminants into waters over which the Respondent has jurisdiction, i.e., Bayou Marcus, Bayou Marcus Creek and Perdido Bay. Increases in these areas will occur in biochemical oxygen demand and undesirable nutrient and dissolved oxygen levels will decrease if this project is constructed. In association with this change, an increase in nuisance species would occur. The Petitioner has failed to do any background sampling to establish the natural background levels of the aforementioned conditions in waters of the State in order to identify whether water quality in the receiving waters would be degraded from existing conditions to the extent of violating the Department's water quality criteria.
Recommendation Based upon a full consideration of the facts as presented and the Conclusions of Law reached in this matter, it is RECOMMENDED that the Secretary of the State of Florida, Department of Environmental Regulation, deny the Petitioner a dredge and fill permit pursuant to Rule 17-4.28, Florida Administrative Code; a construction, operating and maintenance permit pursuant to Section 403.087, Florida Statutes; a ground water permit in accordance with Rules 17-3.071, Florida Administrative Code, and 17- 4.245, Florida Administrative Code; and be it further RECOMMENDED that the Secretary take no further action to require a permit(s) as might be indicated in keeping with Chapter 253, Florida statutes. 1/ DONE AND ENTERED this 22nd day of October, 1980, in Tallahassee, Florida. CHARLES C. ADAMS Hearing Officer Division of Administrative Hearings The Collins Building Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 22nd day of October, 1980.
The Issue The issues in this matter concern Petitioner's requests of Respondent to be granted an after-the-fact dredge and fill permit related to the placement of fill. See Chapters 253 and 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code. Respondent denied this request and this occasioned the formal hearing of February 10, 1984.
Findings Of Fact Petitioner placed a bulkhead waterward of the line of mean high water and the landward extent of the St. Johns River in Duval County, Florida, to improve his property. He then placed approximately 140 cubic yards of fill material in existing wetlands which were located landward of the bulkhead. This was done without obtaining an environmental permit from Respondent. Subsequently, Petitioner discovered that such permit was necessary and on April 28, 1983, he applied to the Department of Environmental Regulation for the issuance of an after-the-fact dredge and fill permit in keeping with the requirements of Chapters 253 and 403 Florida Statutes, and Chapter 17-4, Florida Administrative Code. An on-site inspection was made by reviewing authorities within the Department of Environmental Regulation and, based upon an appraisal of the project, the Department issued a Notice of Intent to Deny the application. The date of the notice was August 15, 1983. A Final Order related to the environmental permit request was issued on August 29, 1983, conditioned upon failure of the Respondent to apply for an administrative hearing within 14 days of the date of that order. Petitioner filed a Request for Formal Hearing on August 31, 1983, and the formal hearing ensued. The placement of the bulkhead and fill material was approximately 15 feet waterward of the line of mean high water in the St. Johns River and 30 feet waterward of the landward extent of the St. Johns River according to the plant indices set forth in Rule 17-4.02(17), Florida Administrative Code. The St. Johns River is a Class III water body and is a navigable waterway over which the state retains possessory and public trust rights. Notwithstanding the fact that the Petitioner has obtained permission from the State of Florida, Department of Natural Resources, related to property rights and utilization of the waters of the St. Johns River in the area of his project, he is not relieved from obtaining an environmental permit from Respondent. The Department of Environmental Regulation has jurisdiction over the construction of the bulkhead and the placement of the fill in the landward extent of St. Johns River, according to Chapters 253 and 403, Florida Statutes, and the associated rules of the Department. The landward extent of the waters of the St. Johns River was determined by the existence of smooth cordgrass (Spartina alterniflora), the dominant vegetation of the area filled by the Petitioner and a variety listed in Rule 17-4.02(17), Florida Administrative Code, as an indicator species of the Department's jurisdiction. That vegetation was covered over by the fill material along the 100-foot wide front in which the fill was placed. The previous existence of smooth cordgrass was established by testimony of the Petitioner's son and the continuing existence of that species in a property adjacent to the Petitioner's land along the St. Johns. The effect of the placement of the fill landward of the bulkhead caused the removal of approximately 1,200 to 1,500 square feet of tidal marsh. That tidal marsh was a vital part in the maintenance of water quality in the St. Johns River. In effect, the vegetation and microbiopopulation in soils served to filter out and assimilate pollutants from upland runoff and from the water in the river, and with the placement of the fill those resources and protections were destroyed. Moreover, water quality standards within Chapter 17-3, Florida Administrative Code, were also adversely impacted with the installation of the fill, including those standards related to BOD, dissolved oxygen, nutrients, and turbidity. Petitioner not only failed to give reasonable assurances that the placement of the fill in its short-term implication would not violate the aforementioned water quality criteria, he has also failed to give reasonable assurances that there will be no violations in the long-term results of the placement of fill. The destruction of the tidal marsh is detrimental to the ecological system in that it takes away detritus which is a necessary part of the food chain. Removal of the marshland is detrimental to the conservation of fish, marine and wildlife, and other natural resources. Petitioner has failed to affirmatively demonstrate that the quality of this detriment will not be contrary to the public interest. In fact, Respondent's presentation shows that the activity of the placement of fill is contrary to the public interest because of the adverse impacts on the natural resources of the area, in that natural marine habitats and grass flats suitable to nursery or feeding grounds for marine life were destroyed when the marshland was removed.
Findings Of Fact Background On January 29, 1981 respondent/applicant, George H. Hodges, Jr. (applicant or Hodges), filed application number 16 39644 with respondent, Department of Environmenta1 Regulation_ (DER), seeking a dredge and fill permit to generally authorize the excavation of 26,000 cubic yards of material from a 3,700 foot portion of an existing channel (Old Pablo Creek) just west of the Intracoastal Waterway (ICW) in Jacksonville, Florida. The channel then proposed was a straight channel along the northern boundary of his property. Hodges also sought to construct two boat slips, three floating docks, an 850 foot vertical bulkhead adjacent to the docks, and to dispose of all dredged material in a diked upland site. Thereafter, DER informally advised applicant that it intended to deny the application for various reasons, including the fact that the dredging would eliminate .75 acres of marsh and wetlands. After receiving this advice, Hodges proposed a series of amendments to his application in 1984 and 1985 in an effort to counter and satisfy DER's objections. The final amendment was made on September 10, 1985. As finally amended, Hodges proposed to confine all dredging to existing salt channels, thereby eliminating the objection that adjacent marshes would be destroyed. Applicant also proposed to restrict his dredging to only 2,250 feet along the northern portion of Old Pablo Creek and to remove 29,250 cubic yards of fill (silt) and sand and place the same in a 12.5 acre upland spoil site. By proposed agency action issued on February 28, 1985, DER announced it intended to issue the requested permit. This prompted a protest and request for hearing from petitioner, Jacksonville Shipyards, Inc. (JSI), which owns and operates a ship repair facility on the ICW just south of the proposed project. In its petition, JSI generally alleged that (a) Hodges had failed to give reasonable assurances that water quality standards would not be violated, (b) the project would adversely affect its property, (c) the project would have an adverse effect on the conservation of fish and wildlife, (d) the project would cause harmful erosion or shoaling, (e) DER failed to consider the long-term effect of the project on marine productivity and the cumulative impact of the project, and (f) the proposed vertical bulkhead did not meet statutory requirements. The Project The project site is a shallow horseshoe shaped creek approximately 3,700 feet in length which meanders through a vegetated salt marsh just west of the ICW in Duval County, Florida. Both ends of the creek connect into the ICW. The site is approximately one-half mile north of the bridge on Atlantic Boulevard which crosses the ICW. The ICW is a man-made channel constructed by the U. S. Corps of Engineers which runs in a north-south direction just east of the project site. It is commonly referred to as Pablo Creek. The channel or creek in which the dredging will occur is known as Old Pablo Creek (creek). An excellent aerial view of the entire area is shown in petitioner's exhibit 4 received in evidence. The creek is a predominately marine water classified as a Class III water of the State. Accordingly, it is subject to DER's regulatory jurisdiction. For purposes of this hearing, the parties have referred to the upper and lower portions of the creek as the northern and southern portions, respectively. Hodges intends to dredge the northern portion of the creek, which measures approximately 2250 feet in length from the ICW to a bend at its western end which crosses Hodges' property and where a residential site is located. According to Hodge's affidavit of ownership, he is the "fee interest owner of adjoining lands except for the dredge channel which is owned by the State of Florida". He acknowledged, however, that the residential site is owned by his superintendent, and that the marshes adjoining the most southern bend in the northern portion of the creek, and the southern portion of the creek, are owned by JSI. Except for the cleared residential site at its western end, the creek is surrounded by vegetation and salt marshes. The vegetated portion of the marsh is marked by a clearly delineated edge which separates it from the creek bottom. The dominant species of vegetation in the marsh are Juncus and Spartina. The marsh serves as a habitat and breeding ground for numerous species, including fiddler crabs, mussels, barnacles, mollusks, faunal communities and gastropods. In addition, the marsh is beneficial because of its biotic productivity and entrapment of nutrients and sediments. For this reason, the habitat should be maintained. Some forty years ago, the portion of the creek that Hodges intends to dredge was eight to twelve feet deep. However, dredging of the ICW by the Corps of Engineers and the placement of fill at the site of the Atlantic Boulevard Bridge have contributed to the shallowing of the creek over time. Today, portions of the creek are exposed and impassable under low tide conditions. Indeed, many parts of the creek are dry during the low tide phase of the ICW. At high tide, the creek is flooded to an approximate depth of four feet. Hodges proposes to dredge the creek channel to a uniform depth of five feet below mean low water (MLW) with side slopes at a 3:1 ratio to restore navigational access from his upland property to the ICW. He has represented that his use of the channel will be restricted to one, or possibly two, small boats for personal use and enjoyment. When completed, the creek channel will have a depth of nine feet at high tide, or an average depth of seven feet over a diurnal cycle. In his amended application, Hodges proposed to confine his dredging to existing creek channels, and to not disturb the actual body of the salt marsh or the vegetation bordering the creek. It is noted that there is no vegetation growing in the existing creek bottom. However, at hearing he conceded that dredging "may include some minor removal of isolated patches of grass growing in the creek channel". One such patch of grass lies in the elbow of the canal which reaches south of Hodges' property, a patch separated from the main body of the marsh by a five foot wide slough deep enough to be navigated at high tide. Hodges estimates this patch of grass to be less than 1/100 of an acre in size (10' x 40') and maintains the effect of its removal would be negligible. The excavation will be effected by means of a Mud Cat hydraulic dredge which operates by suctioning the sediment and water into a pipe. The dredge material (sediment/water mixture) will then be pumped into a series of containment cells on a 12.5 acre upland spoil site that lies approximately one-half mile northeast of the project. Any discharge from the spoil site will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. The natural grade of the existing creek bottom is at or below the mean low water datum. At high tide the existing creek is 4.3 feet deep at its deepest point and gradually slopes upward to a depth of 2.4 feet near the marsh. The elevation of the creek where it meets the marsh is close to mean high water. Even so, the channel width does not always correspond with the mean high water line boundaries of the creek, and creek waters sometimes inundate and extend back into the marsh at high tide. Because Old Pablo Creek is tidally influenced, any water quality violations in the northern portion of the creek can be expected to also have an adverse effect in the southern portion as well. Creek Width Petitioner has raised the issue of whether the creek is as wide as Hodges represents it to be on the drawings attached to the amended application. This is significant since (a) the engineering plans are based upon the assumption that the measurements in the application are correct, (b) the proposed dimensions (depth and side slopes) of the new channel are dependent upon the existing creek having a minimum width of from sixty to eighty feet, as represented by Hodges, and (c) any excavation outside of the existing channel will result in the removal (destruction) of vegetation and marsh. In his application, Hodges reflects the top width of the creek to be sixty to eighty feet, which width will enable him to dredge the channel to an average depth of five feet below MLW, and maintain a side slope ratio of 3:1. This ratio is necessary because of the composition of the sediment in the creek. The minimum top width required to excavate a channel with 3:1 side slopes to a depth of five feet below MLW is fifty- four feet. Petitioner's exhibit 4 identifies five points along the eastern half of the northern portion which have been measured by the parties to determine the actual width of the creek. Although only five points were measured, it may be inferred that these distances are representative of the creek's width throughout its eastern half. At points five through eight, the widths are forty-nine, thirty-five, fifty and fifty feet, respectively, which are less than the measurements contained in the application. If the channel is constructed with the minimum top width (54 feet) required to have 3:1 side slopes, it will result in the elimination of 6 feet of marsh at point 5, 19.5 feet of marsh at point 6, and 4.1 feet of marsh at both points 7 and 8. This equates to the elimination of approximately .33 acres of marsh. Since the above measurements are representative of the eastern half of the northern portion, other areas of vegetation, albeit in unknown proportions, would also have to eliminated. If, for example, applicant attempts to construct a channel within the confines of the portion of the creek that has a top width of only thirty-five feet (point 6), the maximum channel that could be constructed would be V-shaped with a depth of one foot at low tide. Assuming the remaining part of the channel was excavated to -5' MLW, a stagnant area would develop in this portion of the channel and adversely affect water quality. However, to counter the problem at point 6, Hodges intends to remove one patch of grass 10' by 40' in size to achieve the desired width. Any adverse effects on the adjacent marsh at that particular point would be negligible. Because the estimated creek width is not accurate, even the agency now concedes the engineering plans are no longer useful. As a condition to the issuance of a permit, DER has suggested that Hodges be required to submit new certified engineering drawings depicting the proposed cross-section of the channel. It also suggests that the proposed cross-section comply with the top-widths depicted in applicant's exhibit 53, and depict side-slopes of three to one. It further suggests that a condition for the issuance of any permit be a requirement that the 3:1 ratio be maintained, and that other than point 6, no other grass be removed. Finally, the agency proposes that if the new plans and conditions do not permit a -5 MLW depth, the proposed depth be reduced accordingly. However, the evidence supports a finding that either vegetation must be removed at various points along the eastern half of the creek in order to maintain a 3:1 ratio for side slopes, or the depth must be reduced. By reducing the depth at certain points, stagnant areas in the creek will develop, thereby adversely affecting the quality of the water. Further, as noted hereinafter, the validity of the flushing analysis performed by applicant's experts rests upon the assumption that a -5' MLW uniform depth will be used. Finally, the applicant has not given reasonable assurance that the marsh and habitat will not be adversely affected by the elimination of the vegetation which is necessary to achieve the desired depth and concomitant 3:1 ratio. Therefore, the alternative conditions suggested by DER are neither reasonable or appropriate. The Spoil Area The spoil area to be used by applicant is a 12.5 acre upland disposal site approximately one-half mile northeast of Hodges' property. Applicant does not own the upland spoil site but has obtained easements from the owner which expire in March, 1987. In other words, he must complete all work on the project by that date or lose access to the property. The proposed spoil site is completely diked, and is sectioned off into three sections by interior dikes with overflow pipes. Internal baffles and silt fences are also designed into the area. Uncontradicted testimony established that the spoil area is "unusually well designed". Any discharge from the spoil area will be to Greenfield Creek, a tidally influenced creek connected to the St. Johns River. Discharge, if any, will be outfall from an overflow structure in the third section of the spoil area to a dump area land then by sheet flow to salt marshes adjacent to Greenfield Creek. The vegetation in Greenfield Creek consists of a salt marsh expanse of Spartina alterniTlora and Juncus roemerianus. Both species survive in and are indicative of regular introduction of saline waters, and show high tolerance to varying salinity levels. If saline waters from Old Pablo Creek were introduced into Greenfield Creek, it would have no adverse impact on the Greenfield Creek ecosystem. The size of the site was originally designed for a project of 100,000 cubic yards. The site will retain all |effluent from the dredging. The expected total effluent, both sediment and water, is roughly 5.3 million cubic feet of material, assuming a ratio of 6.7 cubic feet of water for each |cubic foot of sediment dredged. This is slightly lower than the 5.4 million cubic feet total capacity of the site. The supernatant from the discharge being deposited into the first cell of the spoil area will only flow into the next cell when the first cell fills and the level of the supernatant rises above the top of the vertical drain pipe overflow structure. If rainfall events cause the cells to fill with water during dredging and discharge operations, the discharge to the next cell or to Greenfield Creek will be primarily fresh water. This will occur because introduction of fresh rainwater into the brackish water from the dredge area will cause stratification, and the fresh rainwater will form a layer on top that will flow into the overflow structure. Turbidity Effects In removing the mud bottom from the creek to a depth of -5' MLW, some turbidity will occur. This is a natural by- product of using the hydraulic dredge. However, the amount of turbidity, and its effect on the waters at the dredge site and discharge point, are in issue. State water quality standards prohibit the discharge of water with a turbidity level greater than twenty-nine nephelometric units (NTU's) above the background levels of the receiving waters. The evidence indicates that the background turbidity levels at the creek are now in the range of ten to twenty NTV's. Excessive levels can result in adverse effects on local biota such as decreasing productivity by reducing light penetration. Excessive turbidity can also be expected to suffocate organisms. The area to be dredged contains sediment deposited from the surrounding salt marsh and carried in from the ICW. The sediment is composed of 14% clay, with the remainder being sand and silt. This was confirmed by a laboratory analysis conducted by JSI. As a general rule, the coarser the material, the faster it tends to settle out thereby creating less turbidity problems. Therefore, sand, which is of a grain size, can be expected to settle out quickly while silt takes somewhat longer. However, clay size particles are much smaller than silt and do not settle out as easily. Applicant made no laboratory analysis of sediment and consequently he erroneously assumed the mud to be sand and silt, and did not take the clay particles into account. The dredging in the creek will cause the turbidity levels to rise to 150 NTU's. However, the placement of a turbidity screen at the entrance to the ICW will prevent the release of this turbidity into that water body. Therefore, if a permit is issued, such screens should be used by Hodges at the dredge site. At the spoil site, clay size particles will also be included in the matter pumped for discharge. If these particles do not settle out, or are not treated, their discharge into Greenfield Creek (a jurisdictional water) will cause violations of the turbidity standards. To counter their effects, flocculants (chemicals) should be added when necessary to the confined material to aid the particles in settling. If a permit is issued, this should be made a condition in the permit. Dissolved Oxygen Impacts The dissolved oxygen (DO) levels in the creek fluctuate on a daily and seasonal basis. As a general rule, DO levels tend to be lower in warmer weather and during the early morning hours. Therefore, a "worst case" situation will generally occur in the summer months in the early part of the day. State water quality standards contained in Rule 17- 3.121(13), F.A.C., provide that in predominately marine waters, the concentrations of DO "shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter." Sampling conducted by petitioner at 5:00 a.m. in early July, 1986 during high tide revealed readings ranging from 3.06 mg/1 in the western portion of the creek to 4.59 mg/1 at the mouth of the creek. Dissolved oxygen levels in the ICW ranged from 3.94 to 4.68 mg/1. Hodges also sampled the creek and ICW in the late morning or early afternoon on August 6,1986 and determined DO levels to be 4.8 mg/1 in the creek and 5.8 mg/1 in the ICW. Testing at that hour of the day produced higher values than those found by JSI. The readings collectively confirm that DO levels in the creek are approximately 1.0 mg/1 less than the DO levels in the ICW. This deficit is primarily caused by the high oxygen demand exerted by the adjacent marsh and muds in the creek. This situation will not be changed by the dredging. The flushing time of the creek channel is an important factor in predicting post-dredging impacts on water quality. Flushing time determines how rapidly waters of the ICW will exchange and mix with the water in the creek channel. Both Hodges and JSI conducted tidal prism studies to determine how many tidal cycles would be required to flush a hypothetical pollutant to 10% of its initial concentration. Under worst case conditions, the channel is expected after dredging to flush every 3 to 4 tidal cycles or 1.6 days. Under more favorable conditions, the creek is expected to flush every 2 to 3 tidal cycles. This compares with the current system which flushes almost 100% every tidal cycle or once every twelve hours. The increased flushing time is due to the significantly greater volume of water that will enter the creek channel after dredging. Because of increased channel depths, the water will move at a slower velocity. Therefore, the oxygen consuming components have a longer period of time to react in the water column. This in turn will cause reductions in DO levels of between .7 mg/l and 1.5 mg/l in the creek. This was confirmed through tidal prism modeling performed by JSI. In this regard, it is noted that JSI's modeling was more sophisticated, better calibrated, and its assumptions were more accurate and reasonable. Consequently, its testing results are considered to be more reliable and persuasive than that of applicant. It must also be recognized that the deepening of those areas that are currently exposed at low tide will allow water to move more easily through the channel and remove some oxygen demanding sediments that now draw from a shallow water column. This will tend to have a beneficial effect on water quality. However, the overall impact of these beneficial effects is unknown, and it was not demonstrated that the otherwise adverse effect on DO will be offset or minimized by the unmeasured impact of deepening the shallow areas. Therefore, applicant has not given reasonable assurance that water quality standards will not be violated by the project. At the same time, it must be further noted that a reduction in the channel depth due to the smaller width of the creek will alter the results of the tidal prism studies, as well as negate some of the beneficial effects caused by deepening the shallow portions of the channel. To what extent the studies are changed, or benefits will be reduced, is not of record. Other Effects of Project As noted earlier, Hodges intends to use one or two boats on the deepened channel. The use of the boats will not introduce pollutants in any significant quantity. Hodges proposes to construct his docks and place rip- rap on the northern side of the widest portion of the creek channel. Little, if any, vegetation will be eliminated by these activities. The use of rip-rap for the construction of the bulkhead is the most environmentally sound means of bulkheading, and will stabilize the shoreline as well as provide habitat for aquatic organisms. The dredging of the creek channel will improve the navigability of the creek, and permit the use of boats in areas where access is now impossible under low-tide conditions. In addition, the sharp bends in the creek will prevent the operation of boats at high speeds. JSI's concern that boats may run aground once they leave the northern portion and enter the southern portion is not meritorious since few, if any, are expected to use the latter part of the creek, and the sharp bends will force boaters to operate at low speeds. Shoaling or erosion of the southern portion will not result from the proposed activities. Indeed, an increased flushing and introduction of new flow into the system may benefit the northern portion. Any situation occurring in that part of the creek should not exceed the rate of siltation occurring under current conditions. The benthic organisms which populate the bottom of Old Pablo Creek include crabs, mussels, barnacles and other species normally associated with estuarine systems. The removal of the mud bottom in the dredging operation may remove some of these organisms. However, this should not significantly change the habitat of these benthic organisms. Rapid recolonization by these species would be expected with recolonization substantially underway within forty-eight hours
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that application number 16-39644 of George H. Hodges, Jr. for a dredge and fill permit be DENIED. DONE and ORDERED this 2nd day of December, 1986 in Tallahassee, Florida. DONALD R. ALEXANDER, Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 2nd day of December, 1986.
Findings Of Fact Mr. Cutter has resided in Taylor County, Florida since 1974. His home is approximately 8,000 feet southwest of the Fenholloway River on the north side of Courtney Grade Road. DEP is responsible for administrating the Water Quality Assurance Trust Fund. DEP's responsibilities include the undertaking of water supply restoration projects in appropriate circumstances. In administering this trust fund, DEP determines whether specific ground water supplies are contaminated. This determination generally requires DEP to evaluate whether a given water supply meets primary drinking water quality standards. A primary drinking water standard is a regulatory criterion adopted by the state pursuant to delegated federal authority. Such a standard refers to a certain maximum level for a given contaminant which, if exceeded, represents a health risk. If DEP finds that a primary drinking water standard is violated, it performs a cost analysis to determine the appropriate means of restoring or replacing a water supply source. In the late 1980's, DHRS received complaints from Taylor County residents that water from their private wells looked, smelled, and tasted bad. DHRS asked DEP to investigate those complaints. DEP's initial investigation of ground water quality did not reveal a public health threat. Nevertheless, DEP decided to proceed on the assumption that industrial effluent in the Fenholloway River could represent a public health threat. DEP first considered the potential of conducting chemical analysis of ground water to detect the presence of chemical markers that would indicate the presence of water from the Fenholloway River. In order to do this, DEP would have to isolate a chemical compound from the industrial effluent in the Fenholloway River that would serve as a "marker" for contaminated effluent. DEP attempted to determine the influence of the Fenholloway River using a test measuring non-purgeable total organic halides, or NPTOX, as a chemical marker. DEP's projections relying upon NPTOX as an indicator for river water proved to be unreliable. DEP correctly rejected the use of NPTOX as a chemical marker because it occurs naturally and does not provide a clear indication as to whether river water influences ground water. Moreover, DEP identified laboratory quality assurance problems for tests using this chemical. DEP's scientists do not know of any practical chemical marker that can identify mill effluent in river water. Research is emerging which may identify a chemical test which will reveal the presence of effluents from kraft paper mills. However, the academic community has not yet validated their use. After the shortcomings of chemical analysis became evident, DEP decided to conduct a ground water study to reach conservative findings regarding the extent to which water from the Fenholloway River could potentially impact ground water supplies in a worst case scenario. DHRS agreed to certify that it would be in the interest of public health to connect homes to a public water system if DEP could identify a corridor where river water influenced ground water. As a result of the ground water study, DEP prepared and adopted the 1995 report titled "Delineation of Ground and Surface Water Areas Potentially Impacted by an Industrial Discharge to the Fenholloway River of Taylor County, Florida" (1995 Report). The 1995 Report identified a conservative potentially impacted corridor within which water from the Fenholloway River might interact with ground water in the adjoining aquifers as well as the potential impact of river flood waters on ground water. Buckeye is a softwood kraft pulp specialty mill that has been in operation in Taylor County since 1954. It discharges treated effluent into the Fenholloway River in accordance with permits from DEP. The mill discharges effluent upstream of U.S. 19 Bridge. This discharge creates a mounding effect, i.e. an artificial high level within the river. Because the river downstream of the discharge point is maintained at an artificially high level during drought conditions, a "mound" of water forms where the water level in the aquifer connects to the river. During a dry season, this discharge will be maintained, but the aquifer on both sides of the river will continue to drop due to a lack of recharge from rainfall. The river generally runs from east to west through Taylor County. It starts in the San Pedro Bay at 100 feet above sea level and ends at the Gulf of Mexico at sea level. Ground water (subsurface water) moves from higher to lower elevations of the water table. Elevations (contours) of equal ground water levels can be mapped just as elevations of land surfaces are mapped. Ground water contour lines (sometimes called equipotential lines) depict points of equal ground water elevation. Direction of ground water flow is always at right angles to the contour lines. Ground water is a dynamic system impacted by rainfall, which adds water to the system, and discharge points, which take water from the system. Water is constantly entering (recharging) or leaving (discharging) the aquifer, which causes the ground water levels to be continually changing. The Floridian aquifer system underlies all of Florida, including the study area of the 1995 Report. The aquifer at issue here is unconfined from San Pedro Bay to the coast. Potentiometric (aquifer water level) elevations of the Floridian aquifer in the study area of 1995 Report show that ground water moves southwesterly. The dominant direction of the ground water flow in this area is parallel to the river. Under normal conditions, with normal rainfall, the river is a focal point for ground water discharge. In this situation, rain recharges the shallow aquifer so that the water level elevations in the aquifer are higher than the water level elevations of the river. Consequently, ground water moves into the river, making it a "gaining stream." In periods of drought when the rainfall is deficient, the recharge is deficient and the water level in the aquifer can decline to points that are lower than the elevation of the water level in the river. In that instance, water can leave the river. If water migrates from the river into the ground water, the river is called a "losing stream." When water leaves the river and migrates outward, it will be influenced by the dominant regional flow that is parallel to the river and downstream. River water can migrate outward a limited distance before it becomes influenced by the regional flow and migrates back to the river. Migration back to the river occurs when water level elevations in the aquifer are higher than they are in the river and the river becomes a "gaining stream." The purpose of the 1995 Report was to define a potential corridor of river influence, using the worst case scenarios in all hydrogeologic conditions. It relied primarily on potentiometric (aquifer water level) studies, as opposed to a chemical analysis of ground water quality. DEP's report relied on differences in water elevations in the river and ground waters. The 1995 Report also relied upon United States Geological Survey (U.S.G.S.)/ U.S. Department of Housing and Urban Development flood prone area maps to delineate the extent of river water flooding on surrounding land surfaces. The area of the study was from east of the mill to County Road 356 in the west, including U.S. 98 to the north and Courtney Grade Road to the south. DEP has not discriminated against certain residents of Taylor County by not extending the geographic boundaries of the study area. The study did not end at Golf Course Road. In order to prepare the MODFLOW model which ultimately led to the MODPATH model, DEP installed additional monitor wells to the west of Golf Course Road. These additional wells provided DEP with ample water level data to perform the models. The monitor wells were more concentrated near the discharge point of Buckeye's mill. However, there were greater fluctuations in water levels in that area. DEP's decision to limit the study to the area depicted in the report was based on technical and policy considerations. Water levels in the areas to the west of the study do not fluctuate very much. Additionally, the influence of the tide from the Gulf of Mexico decreases the impact of river water on ground water south and southwest of the study area. The population in these areas was relatively low. Because the population of Taylor County is dispersed, it is not cost-effective or feasible for DEP to consider the extension of water lines beyond the boundaries of the study area. Mr. Cutter lacks standing to claim that the study did not extend far enough to the west. The western portion of the river beyond the limit of the study could not adversely impact ground water supplying the well on Mr. Cutter's property. DEP collected sufficient data and made an appropriate analysis of the total area depicted in the 1995 Report. The 1995 Report did not use water quality data as a primary or sole indicator of effluent extent. However, it did consider some supplemental chemical concentrations to evaluate water quality. These concentrations were always at or below normal background levels and therefore were consistent with the conclusions in the report. DEP used three techniques to determine the furthest lateral distance that river water could potentially migrate into ground water in the adjoining aquifers. Two techniques (cross-section model and steady-state ground water model) were used to determine the extent of migration during the worst case dry season scenario. The third technique (flood season map) was used to determine the extent of influence on ground water during the worst case river flooding scenario. The cross-section technique used to model the worst case dry season scenario relied upon historical data from the driest period on record (using data from Suwannee River Water Management District, U.S.G.S. and Buckeye monitoring wells), which was April 2, 1989. Using this data, DEP prepared a potentiometric map. A computer program interprets data from a contour map and, given horizontal and vertical axes at given points, produces cross-sections. The cross-sections are made at various angles of the river to determine "stagnation" points," i.e. points where the ground water gradient between the aquifer and the river is zero. DEP staff connected the stagnation points revealed by the cross- section method and transposed them onto a potentiometric map for May 25, 1994 (a dry period where sufficient data was available). This process allowed DEP to define the total area where the river would impact the aquifer during the dry season. The results of the cross-section technique showed that the migration of river water into ground water occurs during dry seasons almost entirely on the north side of the river. It confirmed the analyses of the MODFLOW and MODPATH models discussed below. DEP used a steady-state simulation flow mode as one of the three study techniques in the 1995 Report; it was based on the worst case dry season scenario of April 25, 1989. This model allowed computer tracking of simulated particles (representing river water) in a portion of the 17-mile (north-south) by 20-mile (east-west) grid used in the model. The computer model shows how simulated particles during the worst case dry season conditions: (1) enter the aquifer when the river is higher than the ground water; (2) move away from the river when the river elevation is higher than water level elevations in the adjacent aquifer; (3) reach a "stagnation point" where the elevation of river water that has entered the aquifer is equal to that of the unaffected portion of the aquifer; and (4) subsequently flow parallel with the river and eventually back to the river. The objective of the steady-state ground water flow model (MODFLOW) is to incorporate the best available data so that calibration of model parameters can be accomplished by using measured ground water heads for a specific "snap shot" in time. Once an acceptable calibration of the model is obtained by minimizing the residuals of modeled versus measured heads, then the water budget is decreased by a recharge package so that the model heads closely reflect an observed "worst case" dry season head distribution. After an acceptable dry season head match is obtained, a particle tracking program (MODPATH) is used to delineate effluent migration from the river-to-aquifer and from the aquifer-to- river. U.S.G.S. developed MODFLOW which is a reliable numerical ground water model. DEP used MODFLOW to simulate water levels and to depict hydraulic conditions in the subject area. In the instant case, DEP first examined available data such as water levels, rainfall, and hydraulic conductivity, to develop a conceptual model. The conceptual model determines the size of the model and presents a hypothesis regarding how the area of interest will operate. The development of the conceptual model includes the determination of boundary conditions. Boundary conditions are mathematical instructions which the modeler uses to simplify the model. They reflect the conditions at the geographical limits of the model. DEP used "no-flow" boundary conditions for the north, east and south boundaries. These conditions represent areas where water outside the boundaries flows away from the model. DEP used a "constant head" boundary condition for the western boundary of the model, i.e. a determination that the ground water level does not fluctuate substantially in that area. In developing the conceptual model, DEP also considered relative recharge throughout the area, relative hydraulic conductivity, and drainage conditions. "Calibration" refers to a process where a modeler adjusts factors within the model to minimize the difference between measured water levels and simulated water levels. DEP initially calibrated the MODFLOW model to simulate hydrologic conditions on May 11, 1994. Next, DEP calibrated the MODFLOW model to simulate hydrologic conditions on April 25, 1989 which represents a worst case scenario for a dry season in the study area. U.S.G.S. also developed MODPATH. It is a computer model which uses MODFLOW head (water level) data to simulate the direction of ground water flow. The software simulates where a particle of water would flow based on head data provided by the MODFLOW model. In this case, the MODPATH model yielded a conservative projection of areas where ground water could be impacted by water from the Fenholloway River in a worst case dry season scenario. DEP used a flood season map to delineate the worst case flood season scenario. Historical data indicates that the worst surface river flood on record was Hurricane Dora on September 10 - 13, 1964. DEP used a U.S.G.S. flood prone area map to show the extent of river flooding during Hurricane Dora. DEP conservatively assumed that river flood waters could affect the ground water in the area flooded by the river during this storm. The flood prone map shows areas of inundation flooding from the river and areas of drainage flooding experienced during Hurricane Dora in 1964. The term inundation flooding refers to water that has been in the river which is transported to a certain distance as it floods out of the river banks. The term drainage flooding refers to rainfall which accumulates in a depressed area. Drainage flooding is influenced by the intensity and duration of rainfall and the slope of the depressed area. Since 1955 the U.S.G.S has compiled river water level data in the subject area. Hurricane Dora represents a conservative worst case scenario for a wet season or flood because the water levels resulting from that storm were higher than the levels at any other time in recorded history. Areas outside of the delineated corridor may be flooded from time to time. However, they represent isolated wetlands which are not connected to the Fenholloway River. Therefore, there is no need to include them in the corridor of potentially impacted areas. The corridor in DEP's 1995 Report includes: (a) the entire river flood plain inundated by Hurricane Dora during the worst case flood scenario; (b) the potential extent of river influence during the worst case dry season scenario; and (c) all areas where simulated particles in the steady-state simulation flow computer model computer model migrated from river to ground water, including areas of very low potential. DEP based the computer modeling in the 1995 Report on reliable data from historical records and from the network of monitoring wells in the study area. DEP had sufficient data from the monitoring wells to develop valid ground water elevation maps in the study area for the computer modeling. U.S.G.S. topographic maps are reliable as to elevation numbers. They are commonly relied upon by geologist to determine the direction of surface water flow. U.S.G.S. flood prone area maps depict areas that are impacted by river inundation and are commonly relied upon by geologists. DEP geologists reasonably relied upon the U.S.G.S. flood prone area map of the river. U.S.G.S. river elevation recording station data (from bridges at U.S. 27, U.S. 19 and Route 356 near Hampton Springs) are commonly relied upon by geologist. DEP used proper methods to determine how river water moves during flood conditions. DEP properly excluded from consideration areas that were flooded during Hurricane Dora by local rainfall as opposed to river water. The corridor identified by the 1995 Report correctly reflects a conservative depiction of an area where the river water could influence the ground water in the worst case dry season scenarios, both actual and simulated; it also conservatively depicts the area where the river water could influence surface and ground waters in the worst case flood scenario. The 1995 Report appropriately concluded that there was no potential for areas beyond the defined corridor to be impacted by the industrial waste discharged into the river. Mr. Cutter's property is located within the study area of the 1995 Report but outside the corridor delineated in the report. His property is about one mile from the edge of the 1964 worst case scenario river flood plain. It is situated close to monitoring well number PM02. State agencies have tested Mr. Cutter's well water on several occasions. They have never found any violations of drinking water standards or any exceedances of health advisory levels. Based on the steady-state simulated computer model, river water will not impact Mr. Cutter's property during a dry season worst case scenario. During dry seasons, it is not possible for river water to migrate 8000 feet to Mr. Cutter's land because ground water in the shallow aquifer on the south side of the river is moving from higher to lower elevations toward the river. Consequently, there is no potential for Mr. Cutter's land to be affected by river water during a dry season. River water did not effect Mr. Cutter's property during the 1964 worst case flood scenario, as revealed by the recorded extent of river flooding and the elevation of his land. During Hurricane Dora, the flood elevation of the river was 25 feet above sea level at the nearest point to Mr. Cutter's land which is at least 27-28 feet above sea level. The differences in these elevations makes it impossible for river water to Mr. Cutter's land during the worst case flood scenario. During the 1984 storm, Mr. Cutter's land was about 7-8 feet higher than the recorded maximum river flood waters. The greater weight of the evidence indicates that any flooding on Mr. Cutter's land at that time was the result of drainage or rainfall flooding and not the result of inundation from the Fenholloway River. In the 1994 storm, Mr. Cutter drove from Waldo Springs near the river to his home through less than 18 inches of water. The water was deep enough to reach the floorboard of his vehicle. Mr. Cutter acknowledges that if the topographic maps relied upon by DEP are correct, he would have driven through five feet of water in order for flood water from the river to have reached his land. He stated that the water at his house or in the area between his house and the river was not five feet deep. There are isolated sloughs in the area of Mr. Cutter's land. However, there are no sloughs that continuously extend from the river to Mr. Cutter's property. Therefore, flood water from the river cannot reach Mr. Cutter's land by running through sloughs. Natural conditions, including the decay of organic matter, can cause surface and ground water discoloration. If a well is located near a slough or wetlands, percolation from the slough or wetlands can result in brown well water. There is no persuasive evidence that the discoloration of Mr. Cutter's well water is the result of contaminated river water. The high ground water elevations between Waldo Springs and Mr. Cutter's property act as a barrier to any ground water movement to the southwest in the direction of Mr. Cutter's property. One resident witness testified that his well was contaminated by ethyl dibromide (EDB), a pesticide with no link to river water or kraft pulp mill effluent. EDB is a nematicide commonly used in crops such as citrus and soybeans. It is also used in turf management for golf courses and landscaping projects. Buckeye's mill in Foley, Florida produces fluff wood pulp that is used in products like diapers. It also produces special dissolving wood pulps that are used by the filter industry (including air and oil filters) and the filament industry (including rayon clothing and specialty rayon products used in tire cords). In the kraft pulp mill process, the mill withdraws about 47-50 million gallons per day (MGD) of ground water from the wellfield and discharges about 50 MGD of treated effluent from an aeration pond into the river. The mill has a sewer system that captures the effluent from the manufacturing process. It also has about 150 acres of aerated treatment lagoons. During the time that DEP was studying the issue that resulted in the 1995 Report, Buckeye spent about $2 million providing free bottled water to Taylor County residents and paying the City of Perry to run water lines to homes of people who complained about their well water. Buckeye has a monitoring network of wells around the mill. It maintains liners under its lagoons. Buckeye's interest in this proceeding is: (a) to ensure that it can continue to discharge under its permits from DEP; and (b) to support the 1995 Report of DEP even though Buckeye takes the position that the corridor in that report should be narrower. Buckeye has provided a sufficient basis to support its status as intervenor.

Findings Of Fact Petitioner represents the owner of the property here involved, St. John's Riverside Estates, and was authorized by the owner to prosecute this appeal (Exhibit 19). Some years ago, circa 1960, the owner of the property dredged canals in each of the two parcels here involved, but the plug between the canals and the St. Johns River was not removed. Petitioner now proposes to remove these plugs and maintenance dredge a channel from the location of the removed plug to the St. Johns River. Spoil from the maintenance dredging will be deposited on lands owned by Petitioner. The existing canals are typical dead-end canals which are stagnant at present. By removing the plugs and opening the canals to the St. Johns River, Petitioner will improve the water quality of these canals. Developing the property along the canals as residential homesites will result in additional nutrients and pollutants entering the canals from surface water runoff. Petitioner proposes to use surface water runoff as one method of flushing the canals. Other flushing action would come from tidal flow in the St. Johns River. Although there was some conflict in the testimony regarding the propriety of using the rainfall from a twenty-five year storm event in lieu of of a one-year storm event to calculate the flushing action of the canals by rainfall, use of surface water to flush the canal appears to violate the provisions of Chapter 403, Florida Statutes, respecting water quality. As a condition to the development of the property, Respondent could require Petitioner to hold the surface water runoff in retention ponds to reduce the entry of pollutants into the river. If this was done, percolation and evaporation would further create a substantial reduction in flushing from this source. The St. Johns River is a Class III water body of the state. The water quality of the canals here under consideration are below the state water quality standards with respect to dissolved oxygen levels even using the samples taken during the winter months when dissolved oxygen levels are high. (Exhibits 1, 2 and 3). Generally, dissolved oxygen levels are lower at the bottom of such canals than at the surface. If the samples taken at the surface and bottom during the winter months are averaged for dissolved oxygen content, the result will be above the state minimum water quality standards. However, the dissolved oxygen of samples taken from the canals on May 5 and October 4, 1978, are predominately below the level of 5 mg/l prescribed as the minimum state standard. Removing the plugs would not result in satisfactory flushing of these canals by tidal action. Under the best assumed conditions, it would require 18 tidal cycles or 9 bays to flush 90 percent of the water from these canals by tidal action. An acceptable flushing rate is 2 to 3 days. These canals contain water hyacinths and grasses which increase the biochemical oxygen demand (BOD) which reduces the dissolved oxygen level. Not only do these vegetations reduce photosynthesis by shading the water from sunlight, but also when they die and fall to the bottom, they create a high BOD. Considerable evidence was presented depicting the area, the flora and fauna of the area and the present condition of the water quality of these canals. No evidence was presented to the effect that removing the plugs and allowing interchange between the low quality waters of the canals and the higher quality waters of the St. Johns River would not degrade the water quality of the St. Johns River. Also, no evidence was presented that the residential development of the area as proposed would not increase the coliform count, detergent level, or heavy metals content of the waters of the canals which would further cause a degradation of the river water if the plugs are removed and the waters of the river and canals are interchanged.
Findings Of Fact Petitioner owns a rectangular plot approximately 300 feet (north to south) by 1,300 feet (east to west). The property is within the City of Longwood and is zoned light industrial. The land is undeveloped except for a laminated cabinet factory and warehouse owned by Petitioner. The proposed development includes construction of a paved right-of-way sixty feet wide through the center of the parcel. Entry and exit would be from the east with a cul de sac on the west end. The property would be divided into twenty lots, each facing this street. Petitioner contemplates sale of these lots to light industrial users. A tributary of Soldiers Creek which flows into Lake Jessup and ultimately the St. John's River, separates the eastern one third of the property from the remainder of the parcel. This stream is typically one to three feet deep, with very slow movement. Water in the stream bed becomes virtually stagnant during the dry season. The on-site survey conducted by Respondent's environmental specialist established that the ordinary or mean height water line follows the 52 foot contour, creating a stream bed about 400 feet wide across Petitioner's property. The development proposal calls for filling most of this area, retaining a stream channel one hundred feet wide. Petitioner intends to install four 38" x 60" oval culvert pipes at the stream crossing of the proposed roadway. To control runoff from rain showers, Petitioner plans to construct swells on each side of the roadway and drainage troughs and catch basins are intended to retain runoff pollution. However, during peak rainfall periods, these devices will not prevent direct discharge into the watercourse. Petitioner has not conducted any tests to determine the impact of his proposed project on water quality other than percolation tests associated with the use of septic tanks. The stream is heavily forested with mature hardwood trees. The undergrowth includes buttonbush, royal fern, primrose willow and water tupelo. Clumps of pickerel weed are scattered throughout the stream. The stream bottom consists of one to two feet of leaf litter and accumulated organic muck over firm sand. Respondent's dip net sampling produced numerous least killifish, which are indicative of good water quality. Forested streams and bayheads such as this are natural storage and treatment areas for upland runoff, and tend to reduce the peak runoff discharge to lakes and rivers from rainfall. This, in turn, reduces sedimentation rates and the resultant siltation of downstream waterbodies. The proposed project would eliminate approximately one acre of stream bottom and continuous submerged transitional zone lands. Urban runoff can contain significant amounts of pollutants including nutrients, heavy metals, dissolved solids, organic wastes, and fecal bacteria. In industrial situations, such as that proposed here, concentrations of oils, greases, heavy metals, toxic chemicals, and phenolic compounds from tire wear, paving and use of other petroleum products are anticipated. The discharge of these contaminants would be harmful to the plant and animal life in Soldiers Creek and the subject tributary. The proposed project would not only reduce existing vegetation which serves as a sediment trap and natural nutrient filter, but would create an impervious (paved) surface which would accelerate runoff and would, itself, be a source of pollution. Water quality would be further reduced by the introduction of fill material and the canalization of the stream, which would increase its rate of flow. The Division of Administrative Hearings has jurisdiction over the subject matter and the parties to this proceeding under Section 120.57(1), Florida Statutes. The parties stipulated to Respondent's permitting authority over the proposed fill project. Specifically, Respondent has permitting jurisdiction below the 52 foot contour line which defines the stream bed. See Sections 17-4.02(17), 17-4.02(19) and 17-4.28, F.A.C. Subsections 17-4.28(1) and 17-4.28(3) F.A.C., require Petitioner to establish reasonable assurance that the short term and long term effects of the filling activity will not result in violation of the water quality criteria, standard, requirement and provisions of Chapter 17-3, F.A.C. Petitioner's stream, Soldiers Creek and Lake Jessup are surface waters within the Class III designation of Section 17-3.081, F.A.C. Sections 17-3.061 and 17-3.121, F.A.C., provide the applicable water quality standards and criteria which Petitioner must provide reasonable assurance of meeting. The standards and criteria limit the amount of various chemicals, nutrients, oils and greases which may be introduced as a result of the proposed activity. The evidence adduced herein established that the proposed project would promote substantial changes in these surface waters, degrading their existing quality. These changes would occur through the introduction of oils, greases and other undesirable chemicals and compounds. Further, Petitioner has conducted no specific testing which would establish reasonable assurance that the water quality standards would be met. Petitioner contends that denial of the permit would amount to inverse condemnation or unconstitutional taking of his property without just compensation. Such a determination is beyond scope of this administrative proceeding.
Recommendation From the foregoing, it is RECOMMENDED that the State of Florida Department of Environmental Regulation enter a final order denying the petition of Jack Cruickshank for a fill permit.

Findings Of Fact The permit applicant, Petitioner herein, Gerald M. Hollingsworth, owns approximately 15 acres of land, as described above, bordering Santa Rosa Sound in the vicinity of Mary Esther and Navarre, Florida. The property is adjoined by land owned by Glois A. Brand and Ralph Buckley, neither of whom have objected to the proposed project. Dr. Hollingsworth seeks to dredge a 30 foot by 800 foot channel to connect an existing residential canal constructed some years ago on his property to the six foot bottom contour depth of Santa Rosa Sound. This would involve removing approximately 2,000 cubic yards of sandy material through the use of a barge-mounted dragline and the placing of that spoil above the mean high water line behind bulkheading consisting of a filter cloth membrane, timber and pilings. The bulkheading would be for a linear distance of 400 feet, 200 feet of bulkhead on either side of the mouth of the subject canal where it joins Santa Rosa Sound and above mean high water. The bulkheading is designed to both contain dredge spoil to be generated, as well as to stabilize the mouth and sides of the canal at those points where they are subjected to the greatest erosion-causing energy of wind and wave action. The Petitioner desires to construct the proposed project for use for personal recreational boating activities and has conditioned his application to preclude the commercial use of the canal and dredged channel by a marina or other commercial venture. The existing upland canal was excavated in 1973, but was was never connected to Santa Rosa Sound. The canal does receive tidal flow through a shallow inlet, crossing an approximate 50 foot earthen plug placed in the mouth of the canal, shoreward of the mean low water line. The plug was placed in the mouth of the canal, after a storm washed away the original barrier, by order of the Circuit Court in and for Santa Rosa County. The tidal exchange across the surface of the earthen plug is augmented by the inflow of groundwater through a spring, which provided approximately 1,000 gallons of freshwater to the canal system per hour. Dr. Edwin W. Cake, who holds a Ph.D in biological oceanography, was accepted as an expert witness in the areas of biological oceanography, marine (estuarine) biology and oyster biology. His testimony concerned a survey and study of the biological and ecological characteristics of the canal/lagoon and adjacent sound and expected effects the proposed project will have on water quality in the area of the proposed dredging, as well as its effects regarding conservation of fish, marine wildlife, or other natural resources. His testimony was based upon the results in his survey and analysis, in evidence as Petitioner's Exhibit 4. The study and analysis by Dr. Cake was unrefuted and is found to bee the most accurate depiction of the biological and ecological effects of installation of the channel and removal of the canal plug. Thus, his opinions are accepted as factually correct. It was established that the subject canal was of an average depth of 10 feet, 1,000 feet long and approximately 70 feet wide, after it was dredged in 1975. It was not maintained with sodding, bulkheading or other erosion control and was allowed to vegetate naturally along its banks and to erode and fill in to its present average 6 foot depth. Upland plants mingle with wetland vegetation along the canal banks. The southernmost (seaward) interior of the canal has a marginal band of salt meadow hay now growing with its tidal zone. The northern half of the canal is typified by sparse clumps of salt meadow hay, needle rush, marsh pennywort, arrowhead, switch grass and marsh fleabane, mixed with terrestrial flora such as broom sedge, goldenrod, sea myrtle, marsh elder, ragweed, milky sap shrub, St. Johns wort, forage grass and rabbit tobacco. This marsh vegetation has become established in the canal since it was dredged. The floral community within the canal is a major contributor to the canal's now natural ecosystem and is a minor contributor to the Sound's detrital food chain. The canal in its marginal floral fringes, provides some nursery habitat for local finfish and shellfish. The canal is flooded on a daily basis by saline water from the Sound, driven by tidal energy and prevailing winds. At times of falling or low tide, the canal is a pristine freshwater, to slightly brackish water, habitat that supports varied marine life, such as blue crabs, crawfish and various anthropods. Finfish common in the canal system at low tide include mosquito minnows, sailfin mollies, salt marsh top minnows and sheephead minnows. Upon the rising tide, fish from the saline water of the Sound invade the canal for a brief period and return to the Sound with the falling tide. These transient species include striped mullet, tidewater silver sides and spots. Grass shrimp, as well as blue crabs, enter the canal during times of rising or high tide. The Sound immediately south of the canal (beyond the present plug and freshwater stream outlet) has a paucity of both finfish and benthic invertebrates. Sediment samples reveal that the bottom is dominated by amphipods and razor clams, with blue crabs being observed in shallow, near-shore areas. Mullet and silver sides are the dominant finfish in the Sound outside the canal and in the area of the proposed channel. Santa Rosa Sound is an elongated, relatively shallow mixing basin approximately a mile wide in the project area. It is formed by the mainland coast to the north and the barrier of Santa Rosa Island to the south. The, average depth is approximately 10 feet at mean high water and the proposed connecting channel must span approximately 800 feet waterward into the Sound in order to reach the 6 foot bottom contour desired by the permit applicant. The bottom substrate of Santa Rosa Sound at the site is composed primarily of medium to coarse-grained quartz sand. These sands are covered by a thin detrital layer. There is a prominent layer of peat within the canal and along the Sound shoreline at mean low water just east of the canal. This represents the remnants of a marsh system which dominated the area several hundred to several thousand years ago. That layer of peat is present in a seaward direction in the bottom substrate at distances of 21 feet to 45 feet waterward of the mean high water line at depths of one and a half to two feet beneath the surface of the bottom. Core samples at 150 feet waterward of mean high water showed no peat layer. Core sampling taken from the canal bottom itself showed a very high organic content, but the almost total lack of odor showed that there is a very low biochemical oxygen demand (BOD). Core samples taken from the shoreline out to 800 feet in the path of the proposed channel show very low organic content, less than one-half of one percent. This is a favorable indication for dredging because if organic matter is agitated and suspended by dredging, it tends to reduce the dissolved oxygen (DO) in the water column and its fine grained nature tends to caused a longer lasting turbidity, since fine grained sediments characteristic of organic matter are slow to settle out of the water column as opposed to coarser grained sand material. Thus, the very low organic content in the bottom substrate in the channel area will reduce to a minimum any adverse effect on dissolved oxygen levels and BOD in the Sound water in the area of the project, as well as turbidity caused by the dredging. Because of the great supply of freshwater (18,000 gallons per hour) emanating from the spring in the water bearing strata discharging into the canal at its north end, salinities within the canal are generally lower than in the surrounding Santa Rosa Sound waters. Salinities within the canal at high tide range from zero parts per thousand to 8.3 parts per thousand. The canal is essentially fresh at low tide. Water within the canal is subject to periodic stratification because of reduced circulation patterns and flushing rates related to the existence of the present plug, with a limited inlet and outlet for canal waters to exchange with those of the Sound. Saline water of greater density than freshwater tends to concentrate on the bottom of the canal and the dissolved oxygen content of the canal water showed significantly less DO content near the bottom. At high tide DO ranged from 8.4 to 8.6 parts per million at the surface and from 3.2 to 7.9 parts per million near the bottom where the more saline waters collect. At low tide DO ranged from 7.8 to 8.3 parts per million at the surface and from 3.8 to 8.1 PPM near the bottom, Dissolved oxygen concentrations below 4 parts per million cannot support finfish and benthic invertebrates become stressed at slightly lower concentrations. When dissolved oxygen is totally depleted, a septic condition develops and eutrophication accelerates. The bottom water of the canal thus has a potential for stagnation in the future as long as it is separated from the waters of Santa Rosa Sound in the existing manner. The canal water is relatively clear, however, when compared to that of the Sound and, because of the inflow from a substantial amount of freshwater and the tidal exchange, the canal is not now stagnant and is not a typical "dead end canal." There is presently adequate flushing and dissolved oxygen levels are within appropriate parameters, with the organic buildup in the bottom of the canal not being characterized by substantial anaerobic activity. The large amount of groundwater flowing into the head of the lagoon/canal is significant because such groundwater typically is very low in dissolved oxygen, however, the dissolved oxygen levels in the lagoon are for the most part characteristic of high water quality. Part of this condition is attributable to the enhanced hydraulic flushing caused by the resulting large volumes of water flowing through the lagoon, coupled with the modest tidal exchange possible through the small inlet and outlet flow over the present plug. In the future, however, unless the plug is removed, it is likely that the lagoon will be more and more characterized by low DO readings and that stagnant or eutrophic conditions will occur more and more frequently until they finally predominate in the canal water, with resultant destruction of the presently viable estuarine lagoon biological community, and its substantial value as a nursery area for various forms of marine life. Dr. Stephen Shabica holds a doctorate degree in oceanography. Since receiving his degree in 1976, his principal academic and work experience has been in the field of near-shore oceanography, including the physical, hydrological characteristics and dynamics of moving water and sand. He was accepted without objection as an export witness in these areas. The Department of Environmental Regulation's hydrographic engineer and specialist in hydrodynamics, Pamela Sperling was likewise accepted as an expert witness in her field without objection. Dr. Shabica performed a hydrographic survey and analysis, of wave patterns and sizes at the site, the movement of water and sand at the site, the velocity and direction of prevailing near-shore currents, and historical shoreline changes. He made a survey and analysis of the bottom substrate within the lagoon, including core samples. Ms. Sperling agreed with the methods and practices by which Dr. Shabica arrived at his opinion, including his use of the Army Corps of Engineers Coastal Protection Manual, but differed with his opinion in that she felt the channel would fill with sand deposited by waves and the near shore current, although she acknowledged that would depend on the depth of the channel. She performed no hydrographic survey, tests or studies by the same or other methods in arriving at her opinion in this regard. The calculations and analysis by Dr. Shabica are found to be a more accurate depiction of the effects of installation of the channel and opening of the canal and his opinion is accepted as factually correct. Dr. Shabica thus demonstrated that tides in Santa Rosa Sound are diurnal, with a mean tidal range of 1.4 feet and mean tide level of seven-tenths of a foot in the Navarre area. Tidal predictions are drastically affected by winds, however, the net water movement in Santa Rosa Sound is a westward, slow- moving, along shore current. He found this movement of water to be responsible for a net transport of sand-size particles in a westward direction, referred to as "westward littoral drift." The segment of shoreline bordering the canal property has experienced significant erosion of sand in the past several years, caused by wind generated waves and related currents, tidal currents and the littoral drift process. Because the channel to be dredged will be relatively shallow, with sloped sides, the channel is not likely to act as a catch basin or sump for sediments and thus fill-up because of it. Rather, because of the wave action, as well as the general westward littoral drift caused by the current, sand and sediment would tend to be carried across and past the channel. This lack of a tendency for sediments to settle out in the proposed channel would be enhanced by the large volume of freshwater flowing as a current out of the mouth of the lagoon/canal. There would be be some tendency to the formation of a sand "sill" at the entrance to the canal where the current from the canal is slowed by the relatively stationary or westward moving water in the Sound, such that sand or sediment moving out of the canal would decrease and settle out. In that connection, it was demonstrated by the permit applicant, through Dr. Cake's testimony, that maintenance dredging in approximate five-year intervals would remove this sill and thus maintain adequate flushing in the lagoon system (as well as boat access) and that maintenance dredging at those long intervals will not cause significant permanent damage to benthic flora and fauna communities. The dredging of the connecting channel will result in the removal of a large amount of sand at the south end of the existing canal. During the dredging operation itself, some turbidity would be created in the immediate vicinity of the channel site. That increased turbidity will be slight and of short duration, especially because of the type of dredging equipment used, a dragline on a barge, and because the bottom substrate consists of fairly coarse quartz sand, with a very low percentage of organic material, such that the bottom material will not remain suspended in the water column for a long period of time. It is true that the dredging will destroy most benthic organisms in the immediate locale (24,000 square feet) of the dredging, that is, where the dragline bucket physically disrupts the bottom sediments. Finfish populations and benthic epifauna will return and recolonize the area upon cessation of dredging activities. Infaunal invertebrates will recolonize the area at the next spawning interval. The dredging will not result in any significant deterioration of water quality in the project area. Some water quality parameters may be affected in the immediate area of the dredging, but these effects will be short-term and transitory in nature. For instance, the biochemical oxygen demand (BOD) will not be affected for more than one tidal cycle. Most of the sediments in the area of the proposed channel are well oxygenated and any material requiring oxidizing, such as the layer of peat lying under the sand substrate out to approximately 45 feet waterward of the shoreline, will be physically removed by the dredging activity and placed on the adjoining upland, behind a bulkhead and filter membrane which will control runoff. Oil and grease residues were not shown to pose a substantial pollutant effect of the dredging activity, provided proper equipment, maintenance and supervision is used and practiced (as the applicant has assured). The transitory turbidity caused by the proposed dredging and de-watering of the dredged up spoil will be largely imperceptible after one tidal cycle, or one day, following termination of the dredging activities associated with the project. The predominantly coarse sands in the area will settle out of the water column almost immediately after being displaced vertically or horizontally during the dredging operation. The dissolved oxygen will not be adversely affected by the dredging operation. The sediments in the area to be dredged are very low in BOD and thus their agitation and suspension during dredging and removal will have little effect on present levels of DO in the water at the site. This is especially true since most of the dredged sediments will be deposited on the upland in a harmless fashion. The bacteriological quality of the waters in Santa Rosa Sound itself will not be affected because of the nature of this project, that is the removal of bottom sediments and placing there on an upland disposal area, which does not involve tide addition to the Sound waters of any upland originating pollutant, such as sewage effluent. The nutrient content of the waters in the area of the dredging site and within the lagoon will not adversely affect natural populations of flora and fauna in the immediate vicinity. The opening of the canal to the waters of the Sound will, in fact, increase overall biological productivity of the area and will serve to alleviate any nutrient problems that may occur within the canal by resulting tidal flushing and freshwater outflow. Santa Rosa Sound is not characterized by large salt marsh ecosystems and therefore the presence of the salt marsh system of the Hollingsworth lagoon, albeit of small size, will serve to increase the general biological productivity of the immediate vicinity of the dredge site and serve some pollutant uptake and filtration function. The biological integrity of the channel bottom and sides will decrease insignificantly for a short period of time following dredging. No submerged grass beds will be disturbed since none occur in the channel area. Recolonization by motile benthos and larva of infaunal invertebrates will return the area to its previous state of productivity within less than a year, especially if dredging is in the spring or summer. But the biological integrity of the project area will be enhanced in the long run because of the productive fresh and brackish marsh system that exists inside the lagoon which will be opened to, and exchanged with, the waters of the Sound. The proposed channel dredging will be located in Class II Waters of the State designated for shellfish production and harvesting. A complete sanitary survey of the Santa Rosa Sound has not been conducted since September, 1970, however. That survey was the basic data upon which classification of Santa Rosa Sound as Class II shellfish production and harvesting waters was based. In spite of that classification of the adjacent Sound waters, there are no harvestable populations of oysters, clams or scallops in the immediate vicinity. In addition to proposing the use of a dragline on a barge, which will have the least destructive effect during the process of available methods, the applicant, as found above, will also construct 200 feet of bulkhead in an L- shape, encompassing the shoreline east and west of the canal on each seaward corner, as well as some distance into the canal, behind which all the dredged spoil will be retained. Thus, turbidity caused by erosion of the spoil material from the upland area into the subject waters will be at a minimum. Additionally, canal bank soils will be sodded with grass or turf to stabilize the bank and prevent erosion and the resultant deposition of soil, nutrients, fertilizers, pesticides and other upland pollutants into the waters of the canal. Marsh grass mixed with sod should be placed along the tidal zone of the canal to stabilize sand which would otherwise slump and flow into the canal, causing additional turbidity. The existing canal bank should be allowed to revegetate after dredging and assuming natural balance. The areas of preexisting erosion along the canal banks should be contoured with horizontal pilings, such that the reduced slope caused by the resultant stairway effect would be more erosion resistant. In addition to stabilizing the bank soils, the planting of vegetation on and along the canal shoreline would have the effect of tertiarily treating land runoff and effluent, together with making contributions to the food chain, as well as providing cover for benthic invertebrates, finfish and birds. The use of the bulkheading to retain the dredge spoil on the upland and stabilize the Sound/canal junction, the planting of marsh vegetation along the canal shore, as well as the sodding and contouring of the banks, the shallowness of the channel to be dredged, coupled with the substantial flushing and circulation made possible by the large freshwater outflow of the canal system, will prevent violation of the below-cited water quality criteria. These safeguards, coupled with the above-described characteristics of the project site and manner of the dredging, will adequately protect the project area and areas in the vicinity of the project from significant damage with regard to any shellfish harvesting potential of the Class II waters involved. In summary, the proposed dredging activity and the resultant channel will not interfere with the natural flow of adjacent navigable waterways in a manned contrary to the public interest. It will not present a navigational hazard. The channel will improve onshore/offshore water quality to some extent because the flushing and circulation effect of the approximate 18,000 gallon per hour freshwater outflow added to the normal falling tide outflow. The project in its entirety will not violate water quality standards of the Department, nor will it be contrary to the public interest related to conservation of and beneficial use of fish, marine wildlife or other natural resources. Finally, it should be noted that the permit applicant is presently under the mandate of a court order of the Circuit Court for Santa Rosa County, requiring that a plug be constructed, isolating the canal system from the waters of the Sound, to be constructed according to plans submitted by DER to the court and incorporated in that order. That order remains in effect at this time and any grant of the subject permit should be conditioned upon an appropriate action by the permit applicant to vacate that order. In a like vein, the Department of Natural Resources (DNR) has not issued the appropriate permit for use of the state water bottom involved, therefore a grant of the permit at issue must depend on issuance of the DNR permit. Section 3.77, Florida Statutes.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, and the evidence of record, it is, therefore RECOMMENDED: That a Final Order be entered which grants a permit authorizing the dredging of an 800 foot channel to the 6 foot water denth contour in Santa Rosa Sound, connecting within that 800 foot linear distance the subject canal/lagoon on the permit applicant's upland property with the waters of Santa Rosa Sound, with the channel to be of no greater width than 30 feet and with a depth not to exceed 6 feet; subject to the following conditions: Provided that all dredge spoil is placed upland of mean high water and stabilized with a polyvinyl filter cloth-lined timber and piling bulkhead. Provided that planting of appropriate natural vegetation on and along the canal banks and the above-described "terraced contouring" of the canal banks is accomplished. Provided that, pursuant to Section 253.77, Florida Statutes, a permit for use of state owned water bottoms at the site is obtained from the Department of Natural Resources. Provided the Petitioner has vacated or other- wise obtains relief from that order of the Circuit Court for Santa Rosa County requiring that the canal be plugged.
