The Issue Whether Southern Hy Power Corporation (Hy Power) has provided reasonable assurance, based on plans, test results, or other information, that its proposed hydroelectric facility will comply with the Management and Storage of Surface Water (MSSW) statutes and rules of Southwest Florida Water Management District (SWFWMD) and the Wetland Resource Management permit (WRM)/water quality certification statutes and rules of the Florida Department of Environmental Protection (DEP).
Findings Of Fact By Joint Prehearing Stipulation the parties agreed to the following description of the parties and the project: PARTIES: The Department of Environmental Protection (the Department) is a government agency in the State of Florida existing by virtue of Section 20.255, Florida Statutes, and operating pursuant to Chapters 253, 373, 376, and 403, Florida Statutes, and Title 62, Florida Administrative Code. Under an interagency agreement with SWFWMD, the Department also implements Title 40D, Florida Administrative Code. The Department is located in Tallahassee, Florida, and it has a district office in Tampa, Florida, which district includes Levy County. Southern Hy Power Corporation is a Florida Corporation whose principal offices are located at 7008 Southwest 30th Way in Gainesville, Florida. Betty Berger is an interested party with a mailing address of Post Office Box 83, Inglis, Florida. The Campbells are an interested party with a mailing address of 245 Palm Street, Inglis, Florida. Hy Power applied on August 31, 1993, to the Department for a WRM permit/water quality certification to construct a hydroelectric facility on the Inglis By-Pass Channel. The project is located in Section 12, Township 17 South, Range 16 East, within the town of Inglis in Levy County. The facility consists of a powerhouse located on the south side of the channel measuring about 28 feet wide by 115 feet long, drawing water from the Inglis By-Pass Channel, passing it through a single-pit type turbine and discharging downstream of the Inglis By-Pass Spillway Dam. Hy Power applied on August 4, 1998, to the Department for a MSSW permit for the same proposed hydroelectric facility on the Inglis By-Pass Channel. DESCRIPTION OF PROPOSED PROJECT The project involves the construction of an intake structure, powerhouse, and tailrace on a 0.61-acre area located on the south side of the existing Inglis By-Pass Spillway. The facility will take advantage of the existing hydrostatic head that exists on either side of the Spillway Dam, to generate electricity. The powerhouse will be constructed below grade and will contain a single megawatt turbine and generating unit. The intake structure will divert flows from the upstream side of the Spillway Dam through the powerhouse and back into the By-Pass Channel. A small one-story control building and low profile substation will be constructed above grade within the boundaries of the project area. The hydroelectric project is considered to be a "Run of the River" type of facility because it can only use that water which flows down the existing channel. The geometry of the channel restricts flow to a certain amount, therefore the project cannot create or use flows above those that the By-Pass Channel can provide. The overall authority for control of water levels in Lake Rousseau and flow to the lower Withlacoochee River will remain with the DEP. Lake Rousseau was created in 1909 when the Inglis Dam was constructed across the Withlachoochee River for the purposes of hydroelectric generation. The dam impounds over 11 miles of the Withlachoochee River and forms a lake approximately 3,000 to 4,000 acres in size. Prior to construction of the Barge Canal, water released from the Inglis Dam would flow down the lower portion of the Withlachoochee River about 10 miles before entering into the Gulf of Mexico. In the mid to late 1960's the Army Corps of Engineers (ACOE) built a portion of the Cross Florida Barge Canal between the Gulf of Mexico and Lake Rousseau. The canal severed the Withlachoochee River downstream of the Inglis Dam causing its flow to be diverted into the Barge Canal and then into the Gulf. In order to maintain the flow of freshwater from Lake Rousseau to the lower segment of the River, the 8,900-foot long Inglis By- Pass Channel and Spillway were constructed. The resulting downstream flow ensures navigation in the lower portion of the River and sustains its freshwater and estuarine environment. The water level in Lake Rousseau is generally maintained at an elevation of 27.5 feet above mean sea level (msl) by a combination of the Inglis Dam, the Inglis Lock, which is located in the Barge Canal, and the By-Pass Channel Spillway. These water control features are known collectively as the Inglis Project Works. The water levels in the lower Withlachoochee River immediately to the west of the By-Pass spillway are close to sea level. The resulting head provides the potential energy needed to drive the proposed generator turbine. Under normal conditions the majority of water released from Lake Rousseau flows over the Spillway Dam into the lower segment of the River. According to the DEP Office of Greenways and Trails (OGT), the maximum capacity of the existing By-Pass Channel Spillway is 1,540 cubic feet per second. The hydroelectric project will divert whatever flow is allowed around the existing spillway through the turbine and back into the channel. When the Cross Florida Barge Canal project was cancelled in the 1990's, the ACOE transferred ownership of the property to the State of Florida Board of Trustees, who in turn has leased the property to the DEP for use as the Cross Florida Greenbelt State Recreation and Conservation Area. Management of this property, the control of river flow and lake levels, and operation of the Inglis Project Works are exercised by the DEP's OGT. The OGT utilizes a document entitled "Water Control Plan for Inglis Project Works," dated September 1994, as a guide to operating the structures. The Water Control Plan is incorporated as part of the MSSW intent to issue. On or about April 25, 1995, the Governor and Cabinet, sitting as the Board of Trustees of the Internal Improvement Trust Fund ("Trustees"), approved a request from Hy Power to sublease 0.61 acres of Greenway property at the project site for the purpose of providing electric power. The request was challenged by Berger and the Campbells, and resulted in an administrative hearing held on November 3, 1995. As a result of the hearing, Administrative Law Judge Larry Sartin entered a Recommended Order on July 12, 1996, that the Board enter an order approving execution by the DEP of the proposed sublease and dismissing the petition of Berger and the Campbells. The Recommended Order was approved by the Trustees in its entirety in a Final Order dated April 12, 1996 ("Final Order"). Berger v. Southern Hy Power Corporation et al., Case No. 95-3589. A copy of the Final Order is listed as an exhibit to this Stipulation, and the Findings of Fact and Conclusions of Law contained therein are adopted herein. As previously ruled by the undersigned, the previous Final Order is res judicata as to Petitioners in this case, who are collaterally estopped from challenging any of the findings of fact or conclusions of law contained in the previous Final Order. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Final Order with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the Findings of Fact or Conclusions of Law in the Final Order. On February 21, 1995, Hy Power filed application with the Federal Energy Regulatory Commission (FERC) for a conduit exemption from the licensing requirements of Part I of the Federal Powers Act (FPA) for the proposed project. Petitioners and various other persons filed protests with FERC in opposition to the project. On April 21, 1997, FERC issued an Order Granting Conduit Exemption, a copy of which is listed as an exhibit to this Stipulation. Petitioners in this case are collaterally estopped from challenging any of the findings or conclusions contained in that Order Granting Conduit Exemption. Petitioners reserve the right to litigate issues of fact and law not addressed in the Findings of Fact or Conclusions of Law contained in that Order Granting Conduit Exemption with regard to the permittability of this project under the WRM and MSSW permitting proposals, and to raise objections as to relevance to this proceedings of any of the findings or conclusions in the Order Granting Conduit Exemption. FACTS ADDUCED AT HEARING OUTLINE OF PROJECT The proposed project calls for the construction of a water retention structure along the existing By-Pass spillway, the excavation of a large hole in which the powerhouse and turbine would be constructed "in-the-dry" south of the existing dam, and a millrace below the proposed project to return the water back into the existing water course. Conflicting testimony was received regarding the facts surrounding the construction of the project. These included: whether the proposed project will touch the existing wing walls of the existing dam; whether the water retention structure is a coffer dam; whether the proposed water retention structure will safely retain the water; whether the powerhouse and turbine have sufficient negative buoyancy to stay in the ground; whether the proposed excavation will weaken the existing dam; and whether the de-watering of the excavation site will adversely impact ground and surface water. PROJECT DESIGN AND ENGINEERING Engineering for the project was directed by witness Richard A. Volkin, a professional engineer and president and CEO of Engineering Company, Inc., based in Canton, Massachusetts. Mr. Volkin has extensive national and international experience in the design, management, and operation of hydroelectric facilities. Other engineers in Mr. Volkin’s firm worked on the project under Mr. Volkin’s direct supervision, including John May, who became registered as a professional engineer in Florida in order to sign and seal the engineering drawings for the project, which he initially did around 1994. Mr. May became ill and retired in 1998. Because of the length of time the application process has taken and the fact that Mr. May retired, there was a time while the application was pending, when Hy Power's design team was without a registered Florida engineer. When this was brought to the attention of Hy Power, Hy Power substituted Steven Crockett for Mr. May as the Florida-registered professional engineer of record for the project. DEP routinely accepts an applicant’s changing its engineer of record during the course of permit application or construction. Mr. Crockett is a civil and structural engineer who has considerable experience in preparing dam structural designs. Mr. Crockett independently reviewed and evaluated the engineering drawings for the project. Mr. Crockett resealed the drawings by using his drawn seal and signing the plans because his embossed seal was not readily available and time was of the essence. Mr. Crockett has advised DEP that he is now engineer of record for the project, using the appropriate DEP forms. Mr. Volkin’s firm performed all of the studies required by the various agencies, including a geotechnical study of the area, a 50-year analysis of water flow in and out of the Lake Rousseau regime, and water quality evaluations of water in the By-Pass Channel. The ACOE performed deep hole borings of the soils (approximately 36-40 feet below sea level) in the area of the project site to determine soil stabilization conditions at the site when they were constructing the Inglis Project Works. The soil conditions found can reasonably be expected to be similar today. Mr. Volkin’s company also took its own eight-foot deep surface core samples. The purpose of those samples was to verify the ACOE data. The new core samples verified the original core samples. Mr. Volkin also reviewed the ACOE’s engineering drawings developed from construction of the Spillway Dam. These show that the dam is founded on limestone bedding that has been stabilized with concrete. The hydroelectric facility will be constructed adjacent to and south of the dam structure and adjacent to and north of the barge canal. The same type of limestone bedrock is found in the area of the proposed construction. The facility design includes an intake channel on the upstream channel and a tailrace downstream. Those are the only structures that will be constructed next to the By-Pass Channel. The construction of the facility itself will be "in the dry." Hy Power will use coffer dams to seal off the construction site from the By-Pass Channel, so that there will not be water leakage from the Channel into the construction site. Water from the By-Pass Channel will enter the power plant when the coffer dams are lifted and the water is allowed to flow into the facility. The Petitioners presented the testimony of Bill Edwards, an individual with considerable experience in the construction of bridges, cofferdams, and similar concrete structures in aquatic and semi-aquatic conditions. Mr. Edwards is a former hard-hat diver who worked all over the world and worked in Florida for many years prior to his retirement. Based upon his experience and expertise in construction related to projects of this type, his testimony is credible and worthy of consideration. Mr. Edwards pointed out that if the proposed water retention structure did not touch the wing wall of the existing dam, it could not keep the water out and would not have the strength that it needed to retain the water. Hy Power’s witnesses explained that the retention structure would be set close enough to the existing wing wall that waterproofing materials could be placed between the two structures to keep the water out. Further, that the existing plans did not show interior bracing which would be included for structural strength and integrity. In sum, the retention structure will be in contact with existing dam’s wing wall, but will be free standing and not dependent upon the strength of the wing wall for its strength. Mr. Edwards pointed out that a cofferdam by definition has walls on all sides of the structure. The structure proposed by Hy Power did not have walls all the way around the proposed excavation. In rebuttal, Hy Power presented evidence that its plans were conceptual, design drawing and not construction plans. Hy Power represented that in actuality it would put as many walls as were necessary to keep the water out of the hole it intended to excavate. Trash racks will be constructed at the intake structures to protect aquatic life and make sure that trash and vegetation do not enter the intake structure or go down river. The trash rack bars will be two inches on center, which the U.S. Fish and Wildlife Service has determined as the appropriate size for the protection of fish. The turbine blades are "double regulated," and operate generally between 60 and 90 revolutions per minute. The design enables the turbine to operate at a constant speed to generate a consistent flow of electricity, notwithstanding the fact that the flow of the water may vary. The blade speed is not very fast, and the 2.5-meter blades provide a two to three-foot opening. This design acts to prevent fish mortality. There are four ways to shut off the flow of water through the proposed structure: close the pitch of the blades, close the wicket gates, allow the counter balance to the wicket gates to kick in and automatically close the gates, and close off the main gates. This is a fail safe system ("four level redundancy") designed to work upon any failure. Once water goes through the generator, its velocity is reduced to no greater than its intake rate which is a maximum of three feet per second. This prevents the water being discharged from the tailrace from causing erosion. If the head of water in the dam produces a flow exceeding three feet per second, it can be diverted over the other dams which will be functional. The power plant will be encased in concrete, except for a small access way that enables a person to go down a set of stairs to the plant. It will be a sealed, waterproof structure, as required by FERC and the ACOE. This will prevent penetration of groundwater, or flood waters in the event a massive flood overtops the plant. The only water entering the powerhouse will be through the turbine tunnel for power generation purposes. Mr. Edwards pointed out that the powerhouse was a closed structure and as such would have positive buoyancy, that is, it would float. Mr. Edwards pointed out that the proposed site is between the barge canal and By-Pass spillway and there is a great deal of groundwater and potentiometric pressure in the existing water table. In sum, there is a unlimited supply of groundwater at the site, and powerhouse could float out of the ground just like an empty swimming pool. Hy Power presented rebuttal evidence that the weight of the building, the turbine, and the water flowing through the turbine would be close to negative buoyancy, and they would add additional weight to the structure as necessary to keep it in place. The project is designed to generate three megawatts of electric power which is enough electricity to serve between 300 and 3000 homes, depending on usage. The project is designed to be unmanned. This is common for facilities such as this. The plant can be operated by remote control, unlike the existing controls at the By-Pass Dam, which are operated manually. DEP can access, monitor, and control remotely the generator's operation to include shutting the facility down at any time. There will be remote sensors to monitor water elevations. Flood protection will improve because of the ability of DEP to manage water flow from a remote location. If there is any major disruption, the plant will shut itself down. The project is classified as "green power." In other words, it generates natural energy without any disruption to the environment. The project will have minimal to no impact on the environment. There will be no significant changes in water quality compared to existing conditions as a result of either construction or operation of the facility. WRM Permit Criteria Hy Power has provided reasonable assurances that the proposed project will not cause a violation of state water quality standards of Section 403.918(a), Florida Statutes (1991). The parties stipulated that turbidity and dissolved oxygen were the two surface water quality issues of concern in this proceeding. The receiving water body is the Inglis By-Pass Channel. The Inglis By-Pass Channel is a Class III surface water. The project is not located in a OFW. While the lower Withlacoochee River is an OFW, the OFW designation runs up the natural river itself, and does not include the Spillway Dam, tailrace, or the remainder of the By-Pass Channel. There would be no degradation of water quality at the point of contact with the Withlacoochee River OFW. The DEP and FERC looked specifically at potential for turbidity and dissolved oxygen in determining whether the project would violate state water quality standards. The standards for turbidity and dissolved oxygen will not be violated. Because the By-Pass Dam is an under flow structure, a minimum of oxygenation currently occurs as water flows through the existing dam. The proposed project runs the water underground through the generator; however, Hy Power will measure the dissolved oxygen below the dam in the Lower Withlacoochee River. In the event there is any lowering of dissolved oxygen, Hy Power can install a "sparge ring" to reoxygenate the water going through the turbine so that dissolved oxygen remains at current levels. No turbidity will be added to the receiving water as a result of the project, because water velocity is low and the structure is encased in concrete and rip-rap. The only other potential for turbidity would occur when the coffer dams are removed after construction is complete. The coffer dams can be removed with the generator closed to permit any turbidity to settle. The amount of siltation that might occur when the generator is opened would be insignificant. Where a project is not in a OFW, an applicant must provide reasonable assurance that the project will not be contrary to public interest. See Section 403.918(2), Florida Statutes (1991). Hy Power has provided such assurances. The project will not directly affect public health, safety or welfare, or the property of others. See Section 403.918 (2)(a)1., Florida Statutes. There are concerns relating to the structural integrity of the proposed facility and adjacent structures which are discussed extensively below. The project will have no adverse impact upon the conservation of fish and wildlife, including threatened and endangered species and their habitat. See Section 403.918 (2)(a)2., Florida Statutes. While manatees are not likely to be found at the project site, the installation of the trash racks will eliminate any potential adverse impact on manatees. In fact, the racks will be an improvement over the current unprotected Spillway Dam. DEP procedures require a specific manatee control plan be implemented to deal with site specific concerns. The project will not adversely affect navigation or the flow of the water or cause harmful erosion or shoaling. See Section 403.918(2)(a)3., Florida Statutes. The project will not adversely affect fishing or recreation values or marine productivity in the vicinity of the project. See Section 403.918(2)(a)4., Florida Statutes. The permanent project and its construction will cause no significant environmental impacts. See Section 403.918(2)(a)5., Florida Statutes. There will be no adverse impacts to significant historical and archeological resources. Section 403.918(2)(a)6., Florida Statutes. With regard to the impact on current conditions and relative value of functions being performed by the areas affected by the proposed activity, there will be no negative impacts. See Section 403.918(2)(a)7., Florida Statutes. Improvement will result from better control of water flow at the project site, installation of trash racks and implementation of green power. THE FORESEEABLE ADVERSE SECONDARY OR CUMULATIVE IMPACTS Potential adverse secondary impacts related to power transmission are addressed through the fact that there is an existing power line corridor that can be used to transmit the electricity. Any need to change the corridor could be addressed by subsequent DEP permitting. Cumulative impacts are not at issue. Mr. Gammon, with Florida Power, acknowledged that the current electric company, presumably Florida Power, would be required by FERC to transport the electricity generated by Hy Power over its existing corridor and poles. No final decision has been made regarding how to access the site with equipment during construction. Several feasible construction options exist, and there are several ways of accessing the site with heavy equipment vehicles and without impacting wetlands. Any final decision would be subject to DEP approval. Since the project meets the public interest criteria of Section 403.918(2)(a), Florida Statutes, and wetland impacts are minimal, the project is permittable without the need for mitigation. See Section 403.918(2)(b), Florida Statutes. The ACOE has issued a permit for the facility. The permit varies slightly from the DEP intent to issue in the use of reinforced concrete rather than rip-rap on the bottom half of the intake channel. This is to comply with ACOE preference, but the variation has only an environmental benefit. Counsel for Petitioners sought to elicit testimony from Linda Sloan, Executive Director of the Withlacoochee Regional Planning Council, with regard to compliance of the proposed project with the Town of Inglis Comprehensive Plan and Land Development Code. Such compliance is not relevant to this proceeding. At any rate, Ms. Sloan conceded that any prohibition that might apply in the Land Development Code to construction of the proposed facility could potentially be alleviated by exemption or variance provisions in the Code. MSSW PERMIT CRITERIA The project will provide adequate flood protection and drainage in the conventional sense. See Rule 40D-4.301(1)(a), Florida Administrative Code. Because the amount of impervious area is minimal, runoff from the project will not in any way contribute to increased flooding or adversely impact drainage patterns. The total amount of impervious area of the facility is less than that of a single-family residence. SWFWMD rules do not even require MSSW permits for single-family residences because the impact is not significant. The only purpose for requiring a MSSW permit for the project is to review the project’s potential downstream impacts to the watershed, not stormwater runoff from the facility itself. The project will not cause adverse water quality or water quantity impacts on adjacent lands in violation of Chapter 373, Florida Statutes, or cause a discharge that violates state water quality standards. See Rule 40 D-4.301(1)(b), Florida Administrative Code. As indicated by the WRM water quality findings above, the project will not generally violate state surface water quality standards. See Rule 40 D-4.301(1)( c), Florida Administrative Code. The project will not generally cause adverse impact on surface or groundwater levels or flows. See Rule 40 D- 4.301(1)(d), Florida Administrative Code. Since the project is a run-of-the-river, it will not diminish the capability of a lake or other impoundment to fluctuate through the full range established for it under Chapter 40D-8, Florida Administrative Code. The project will not cause adverse environmental impacts, or adverse impacts to wetlands, fish, and wildlife or other natural resources. The project can be effectively operated and maintained. See Rule 40D-4.301(1)(g), Florida Administrative Code. The project is a slow speed, low maintenance facility. The design concept is well established and has been successfully used for many years. Possible adverse affects to public safety are discussed below. The project is consistent with the requirements of other public agencies. See Rule 40D-4.301(1)(i), Florida Administrative Code. Potential harm to water resources within the SWFWMD are discussed below. See Rule 40D-4.301(1)(j), Florida Administrative Code. The proposed project generally will not interfere with the legal rights of others. See Rule 40D-4.301(1)(k), Florida Administrative Code. The proposed project is not against public policy. See Rule 40D-4.301(1)(l), Florida Administrative Code. The project complies with the requirements contained in the Basis of Review. See Rule 40D-4.301(2), Florida Administrative Code. There is a dispute as to whether the project was within or at the edge of the 100-year flood plain. This dispute is related to how one interprets the rule as it relates to the millrace and the location of the facility which is under ground. In the conventional sense, the project is not in the flood plain. Further, the project is designed in such a way, that it is waterproof if it were topped with water. While in the past SWFWMD may have had concerns that the project might cause downstream flooding, SWFWMD currently has no such concerns, given the run-of-the-river status of the proposed project. The operation of the project will not cause downstream flooding. The DEP included in its intent to issue, conditions contained in the sublease between Hy Power and the DEP in order to ensure that the facility would remain run-of-the-river, would comply with the water control plan, and would otherwise comply with the terms of the sublease. The DEP has final control over water flow and can revoke the permit or otherwise take enforcement action against Hy Power if Hy Power fails to comply with the water control plan. GROUNDWATER IMPACTS Operation of the project will not cause groundwater contamination or otherwise have adverse groundwater impacts. Some concerns about groundwater during excavation of the construction site were raised. The conflicting evidence received regarding them is discussed below. An area of concern was the de-watering plan for the project. Everyone agrees there will be some water seepage into the construction site that will have to be pumped out. The parties disagree regarding the amount of water that will have to be removed. Their estimates of amount of water to be removed vary because their estimates of size and over-all depth of the site vary. Petitioners presented credible evidence that a potential exists for the construction site to have a large quantity of water because of its location between two sources of surface water (the By-Pass Channel and Barge Canal), because of the makeup of the subsurface, and because of the depth of the construction. Hy Power credibly represents that if excessive groundwater is found, it can address the adverse impacts through its de-watering plan that would have to be filed with FERC and DEP. The technology exists to address the de-watering of the project. Such plans are routinely considered by DEP after a construction permit is issued and before de-watering occurs. There is very little evidence of sinkhole activity in the project area, and the construction activities are not expected to cause any sinkhole activity. NOISE POLLUTION Mr. Bitter expressed concerns that FERC would require the facility to install a very loud siren that would result in sudden noise adverse to the well-being of neighbors. Mr. Bitter is unfamiliar with FERC siren requirements at run-of the-river hydroelectric facilities. In contrast, Mr. Volkin, who has substantial experience in this area, testified that the only alarm device that would be required would be for the protection of the workers during construction. The purpose of the alarm is to warn persons below a dam spillway of a change in the volume of water being let out of the impoundment. In the case of a run-of-the-river facility, the volume is near constant, changing only gradually. Therefore, even if a warning siren had to be installed its use would be limited to significant changes in flow or testing. This would not constitute a nuisance. Further, the facility is located in the vicinity of the Crystal River Nuclear Power Plant which has its own warning sirens. It would be prudent to make any warning devices required for this structure significantly different from those at the nuclear plant and to limit their use. DAM SAFETY AND FERC REVIEW In reviewing whether Hy Power’s applications complied with the relevant permitting criteria, the DEP took into consideration the review of the facility already performed by FERC. FERC will also be responsible for reviewing the project as it is being constructed. Mr. Edwards also raised concerns about the structural stability of the By-Pass Dam itself. This has been a subject of concern by those responsible for the dam, and a survey of the structure was conducted in 1993, referred to as the Greiner Report. The Greiner Report identified specific maintenance problems that have been and are being addressed by the DEP. However, DEP’s maintenance plan does not address specifically the possibility that the weight of the dam over time has caused some shifting in the dam. Hy Power has only a few core borings and only one at the location of the generator. Hy Power is using the ACOE’s original borings, as confirmed by several new ones, to develop its preliminary plans. The DEP considered FERC and the ACOE as responsible agencies for determining the structural integrity of the dam. DEP has taken FERC’s review of this facility into consideration as part of DEP’s own permitting review. It is normal for DEP to rely on outside sources and agencies for assistance in determining compliance with DEP permitting criteria such as public health and safety, and it is reasonable for DEP to do so in this instance. Most states do not have the full capability to evaluate dam safety, and so they rely on FERC and ACOE. On April 21, 1997, the project received a conduit exemption from FERC. The application process is illustrated in Hy Power Exhibit 11. Hy Power submitted to DEP detailed information about the dam, the associated structures and the proposed project which had been reviewed by FERC and the ACOE, the two agencies in the United States who are responsible for dam structure design, control, and administration. Included in the package was the Greiner Report and Hy Power’s review of it. FERC evaluated the project, the Inglis By-Pass Dam structure, and the proximity of the project to the Dam in relation to structural impact, upstream and downstream impacts, water quality, and environmental issues. Mr. Edwards raised concerns regarding the ability of the limestone bedrock to sustain additional construction in the area of proposed construction. This is a material issue in the controversy which impacts several aspects of the proposed construction. Mr. Edwards pointed out that the barge canal channel was constructed with the use of explosives that caused a fracturing of limestone bedrock. He pointed out that the steel panels, which Hy Power proposes to drive into the bedrock to construct the water retention structure necessary to excavate the hole into which the turbine and powerhouse would be placed, will further fracture this bedrock. This creates two potential dangers. It could permit water to move under and around the bottoms of the panels, potentially scouring the loosened material from the base of the panels and making them unstable and subject to failure. It could weaken the entire southern wing of the existing spillway dam. Mr. Edwards opined that this could result in catastrophic failure of the dam or the coffer dam. Such a failure would cause major destruction and loss of life to those persons living and working in and along the lower Withlacoochee River. Hy Power presented rebuttal evidence that it could and would, if necessary, inject concrete into the limestone to stabilize it and avoid the concerns raised by Mr. Edwards. FERC specifically evaluated concerns raised by project opponents over the poor physical condition of the By-Pass Channel Spillway structures, relying particularly on the 1993 Greiner Report. FERC noted that the DEP had entered into a contract to correct any deficiencies listed in the Greiner Report, which "did not conclude that the deficiencies at the By-Pass Spillway threaten downstream life and property." The FERC review concluded that the dam was safe. To ensure safety, FERC is requiring that Hy Power do a complete stability analysis of the dam prior to any construction. Articles 301 and 302 of the FERC exemption ensure that all final drawings and specifications be submitted to FERC prior to construction, along with a supporting design report consistent with FERC’s Engineering Guidelines; that FERC can require changes to assure a safe and adequate project; and that Hy Power must also submit approved coffer dam construction drawings and specifications at least 30 days prior to starting construction. FERC has its own engineering staff who will go to the site and do their own analysis, along with the ACOE, of the dam and structures, prior to any construction commencing. This is a detailed design review evaluation so that the latest information on the dam will be made known immediately prior to construction, and will prevent any catastrophic event from happening. Under FERC procedures, FERC requires the applicant to obtain the DEP permits prior to requiring applicant to submit more detailed construction designs for FERC's consideration. These more detailed designs in turn will be subject to further review by DEP and FERC. It is assumed that Hy Power will comply with the post- permitting procedures and requirements, and will present complete, detailed construction drawings for FREC and DEP approval. Hy Power’s failure to complete the process would result in denial of a construction permit.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law set forth herein, it is RECOMMENDED: That the DEP enter a Final Order that issues the two permits challenged in this proceedings, WRM Permit No. 38-237096-3.001 and MSSW Permit No. 38-0129249-002, subject to the conditions contained in the Intents to Issue in the respective WRM and MSSW Permits and as described in the Recommended Order.

The Issue Whether the Petitioner (the District) has the authority and cause to revoke Right of Way Occupancy Permit Number 9591 that permitted Respondent to erect a fence and maintain two oak trees on real property that is subject to the District's maintenance easement and, if so, whether the District has the authority and cause to demand the removal of the fence, the two oak trees, and a key lime tree from the easement area.
Findings Of Fact Respondent is the owner of a single family residence located at 7900 Southwest 173rd Terrace, Miami, Florida. The rear of Respondent's property backs up to the north right of way of the District's C-100 Canal. The C-100 Canal is one of the works of the District and is an essential part of the District's flood control plan. The C-100 Canal system supports surface drainage and flood protection to approximately 40 square miles of Dade County, Florida. The property owned by the District in fee simple includes a strip of land that is adjacent and parallel to the north bank of the canal. This strip of land is twenty feet wide and provides the District with a portion of the land it requires for maintaining the canal. On February 18, 1964, Respondent's predecessor in title executed a document styled "Permanent Maintenance Easement" that granted to the District's predecessor agency an easement on and across a strip of land that constitutes the rear twenty feet of Respondent's property. The easement area is adjacent and parallel to the maintenance strip owned by the District. The instrument granting the easement provided, in pertinent part, as follows: . . . the grantors do hereby grant, bargain, sell and convey unto the grantee . . . its successors and assigns, the perpetual maintenance easement and right for and to the use and enjoyment for canal maintenance purposes of the following described lands . . . for the purpose of ingress and egress in maintaining and operating Canal C-100, one of the works of the District . . ., and for no other purpose, it being understood and agreed that said land shall not be excavated and that no permanent structure of any kind shall be placed thereon. . . . All the covenants and agreements herein contained shall extend to and be binding upon the parties hereto and their respective . . . successors and assigns. On April 9, 1992, the District issued to Respondent Permit Number 9591 which, subject to limiting conditions, authorized certain encroachments by Respondent into the easement area and described those encroachments as follows: 4' high chain link fence enclosure encroaching 20' and 2 trees inside the fenced enclosure within the District's 20' canal maintenance easement along the north right of way of C-100 located at the rear of 7900 Southwest 173rd Terrace. Permit 9591 provided, in pertinent part, as follows: . . . The Permittee [the Respondent], by acceptance of this permit, hereby agrees that he shall promptly comply with all orders of the District and shall alter, repair or remove his use solely at his expense in a timely fashion. . . . . . . By acceptance of this permit, the permittee expressly acknowledges that the permittee bears all risks of loss as a result of revocation of this permit. The District has enacted Rule 40E-6.381, Florida Administrative Code, which provides the following standard limiting conditions of Permit 9591 pertinent to this proceeding: The District's authorization to utilize lands and other works constitutes a revocable license. In consideration for receipt of that licensure, permittees shall agree to be bound by the following standard limiting conditions, which shall be included within all permits issued pursuant to this chapter. * * * (3) This permit does not create any vested rights, and . . . is revocable at will upon reasonable prior written notice. Permittee bears all risk of loss as to monies expended in furtherance of the permitted use. Upon revocation, the permittee shall promptly modify, relocate or remove the permitted use. In the event of failure to so comply within the specified time, the District may remove the permitted use and permittee shall be responsible for all removal costs. * * * (7) The permittee shall not engage in any activity regarding the permitted use which interferes with the construction, alteration, maintenance or operation of the works of the District, including: * * * (c) planting trees . . . which limit or prohibit access by District equipment and vehicles, except as may be authorized by the permit. Among the special limiting conditions of the permit are the following: The permittee is responsible for pruning trees in order that their canopies do not encroach within areas needed by the district for canal maintenance purpose. Upon the request of the district, the permittee shall trim or prune any growth which the district has determined interferes with the district's access, operations, and maintenance. Permittee shall be responsible for the maintenance of the canal right of way within the fenced area and also for the maintenance of the right of way to a point 10 feet outside the fenced area. At the time of the formal hearing, the easement area was enclosed by the fence that Respondent erected pursuant to Permit 9591 and there existed within the easement area two live oak trees and one key lime tree. The two oak trees were approximately ten years old. The evidence did not establish whether Respondent planted (or transplanted) the two oak trees. The key lime tree was planted by Respondent after the issuance of Permit 9591. It is necessary that the C-100 Canal be properly maintained and that the District have access to the canal for routine and emergency maintenance. Following Hurricane Andrew in August 1992, the District developed a maintenance plan for the C-100 Canal. The District did not have an established canal maintenance plan for the portion of the canal relevant to this proceeding at the time it granted Permit 9591. Prior to the development of its maintenance plan, little maintenance had been done on the canal in the area of Respondent's property. The District's decision to revoke Permit 9591 and to demand the removal of the fence and trees is in furtherance of the District's right of way maintenance plan and is only part of the District's enforcement and management efforts to remove permitted and non-permitted encroachments from maintenance easements in this area of the C-100 Canal. Respondent's property has not been singled out for this action. At the time of the formal hearing, Respondent's property was the only area in the vicinity on which the District does not have 40' of unobstructed access adjacent to the canal. Respondent disputes that the District needs access to the portion of his property that is subject to the easement for the proper operation and maintenance of the C-100 Canal. Pertinent to this proceeding, the maintenance plan adopted by the District includes the use of land based equipment for erosion control and mowing of maintenance right of way areas and the routine and emergency dredging of the canal channel. The plan sets forth the anticipated maintenance activities for the area of the canal relevant to this proceeding, the type equipment that will be used, and the amount of right of way that will be required to perform the work. Emergency maintenance of the canal may be required in response to a heavy rain event since the District must be able to respond quickly if a part of the canal becomes clogged with debris. The equipment that the District will likely use for maintenance includes batwing mowers, front end loaders, dump trucks, draglines, and towboats. The District established that the 20' strip of land it owns in fee title does not provide sufficient room for the maneuvering of the heavy equipment that will be required for the routine and emergency maintenance of the canal. These pieces of heavy equipment require 40' of unobstructed land to set up and to operate safely and effectively. The District established that it needs the additional area provided by the easement on Respondent's property to properly perform its operation and maintenance of the C-100 canal. The fence that Respondent erected pursuant to Permit 9591 blocks the District's access to the easement area. Consequently, it is found that the District has cause to revoke Permit 9591 as it pertains to the fence. The District's easement entitles it to unobstructed access to the easement area and provides the District with the authority it needs to demand that Respondent remove the fence. The District established that it has cause to demand that Respondent remove the fence from the easement area. Respondent also disputes that the two live oak trees and the key lime tree that are in the easement area need to be removed even if it is found necessary to remove the fence. In their present condition, the three trees, especially the two oaks, obstruct a major portion of the easement area and interfere with the District's intended use of the easement area. Even if the trees are pruned as they grow to maturity, they will significantly interfere with the District's intended use of the easement. The bases of the oak trees are approximately 2.5' and 6.5', respectively, from Respondent's rear property line within the easement area. The two oaks are approximately the same size and are expected to grow to maturity at the same rate. At the time of the formal hearing, the canopies of the trees were approximately 20' tall and 10' wide. In five years, the canopies are expected to be approximately 25' tall and 25' wide. In ten years, the canopies are expected to be 30' tall and 30' wide. At maturity, the canopies are expected to be 35' tall and 40' wide. The District has cause to revoke Permit 9591 as it pertains to the two oak trees. The District also has cause to demand that Respondent remove the two oak trees from the easement area. The instrument granting the District the maintenance easement provides the District with the authority it needs to demand that Respondent remove the two oak trees. The base of the key lime tree is approximately 10' from Respondent's rear property line within the easement area. Although this is a relatively small tree, its presence obstructs the operation of equipment within the easement area. At maturity the canopy of the key lime tree is expected to be between 12 to 15' in height and between 12 and 15' in width. The tree trunks and the tree canopies obstruct the operation of equipment within the easement area. This interference cannot be resolved by pruning the trees. The District has cause to demand that Respondent remove the key lime tree that he planted on the easement area since that tree was not permitted by Permit 9591 and is contrary to limiting condition 7(c). The existence of the key lime tree is found to interfere with the District's intended use of the easement. The instrument granting the District the maintenance easement provides the District with the authority it needs to demand that Respondent remove the two oak trees.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the District enter a final order that revokes Permit 9591 and demands that Respondent remove the fence, the two oak trees, and the key lime tree from the easement area within thirty days from the date the final order becomes final.

Findings Of Fact Background Petitioner, David E. Musselman, is the owner of Lot 23, Block 22, Cudjoe Gardens Eighth Addition, Cudjoe Key, Monroe County, Florida. The lot measures 127 feet along its front and rear property line, 135 feet along its side property lines and, similar to adjacent lots, its rear property line abuts an artificially created waterway. Currently, most of petitioner's lot enjoys an elevation of six feet; however, from the edge of the waterway landward a distance of approximately 20 feet [to what has been referred to as the "toe of the existing slope" in these proceedings] the surface consists of exposed caprock at an elevation of approximately four inches above mean high water. It is petitioner's desire to construct a single family residence upon such lot and, incident to such construction, to erect a seawall along the edge of the waterway such that the elevation at the waterway will be increased by two feet, and to backfill from the seawall to his home. Such backfilling would require the deposition of approximately 3,540 square feet of fill within the Department's jurisdiction, which was shown to extend from the edge of the waterway to the toe of the existing slope, and would raise the elevation in such area two feet above existing grade. On December 16, 1991, petitioner filed an application with respondent, Department of Environmental Regulation (Department), for an exemption from the Department's wetland permitting requirements. If approved, such exemption would allow petitioner to construct the vertical seawall along the waterway, and backfill from the seawall to his proposed home. By notice of agency action dated February 14, 1992, the Department proposed to deny petitioner's application predicated on its conclusion that his proposal did not meet the exemption criteria established by Rule 17- 312.050(1)(g), Florida Administrative Code. Petitioner filed a timely protest to contest the Department's conclusion. The exemption Pertinent to this case, Rule 17-312.050(1)(g), Florida Administrative Code, exempts from permitting the following activities: (g) Construction of seawalls or riprap, including only that backfilling needed to level the land behind the seawalls or riprap, in artificially created waterways where such construction will not violate existing water quality standards, impede navigation or adversely affect flood control. An artificially created waterway shall be defined as a body of water that has been totally dredged or excavated and which does not overlap natural surface waters of the state. For the purpose of this exemption, artificially created waterways shall also include existing residential canal systems . . . . At hearing, the parties stipulated that the waterway which abuts the rear property line of petitioner's lot is an artificially created waterway, as well as an existing residential canal, and that the proposed project will not violate existing water quality standards, impede navigation, or adversely affect flood control. Notwithstanding, the Department contends that petitioner's application should be denied because no need has been demonstrated that would support the construction of the seawall along the edge of the waterway, as opposed to locating it further inland, and therefore the amount of backfill, with its attendant loss of wetlands, is excessive. For the reasons set forth in the conclusions of law, the Department's position is untenable as a matter of law. 1/
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department enter a final order approving petitioner's application for an exemption to construct a seawall, and to backfill from such seawall to his proposed home, as applied for. DONE AND ENTERED in Tallahassee, Leon County, Florida, this 4th day of June 1992. 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 4th day of June 1992.
The Issue The issue in this case is whether Respondents Paul Crum, Sr., and Paul Crum, Jr. (the "Crums"), are entitled to the Noticed General Permit issued by the Department of Environmental Protection ("Department") for the construction of a single- family residential dock and associated structures.
Findings Of Fact Background The Crums are the owners of the riparian property located at 15696 Shark Road West, Jacksonville, Florida. The Crum property is adjacent to Pumpkin Hill Creek, which lies within the Nassau River-St. Johns River Marshes Aquatic Preserve. Extending from the Crum property into Pumpkin Hill Creek is an existing wood dock approximately 90 feet long and four feet wide, with a platform near the landward end of the dock. Petitioner Brooks owns the property immediately adjacent to and north of the Crum property. Petitioner Brooks has a dock and boat lift. Petitioner Cole owns the property immediately adjacent to and southeast of the Crum property. The Cole property is located on a salt marsh and has no dock. Petitioner Jones lives approximately 3,200 feet north of the Crum property, on a tributary to Pumpkin Hill Creek. Petitioner Jones has fished Pumpkin Hill Creek and the surrounding waters for over 25 years. Noticed General Permits are a type of environmental resource permit granted by rule for those activities which have been determined to have minimal impacts to water resources. Florida Administrative Code Rule 62-341.427 grants by rule a general permit to construct a single family pier, along with boat lifts and terminal platforms, provided certain specific criteria are met. In August 2005, the Crums applied for a Noticed General Permit to extend their existing dock into deeper water. The Department issued a Notice of Determination of Qualification for Noticed General Permit, but later rescinded the authorization after Petitioner Brooks complained to the Department that the landward end of the existing dock is located only 21 feet from her property boundary and, therefore, did not comply with Florida Administrative Code Rule 18-21.004(3)(d), which requires that a dock be set back a minimum of 25 feet "inside the applicant's riparian rights lines." In November 2005, the Crums re-applied for a Noticed General Permit. Their revised plans called for removal of the existing dock and construction of a new dock extending approximately 255 feet out into Pumpkin Hill Creek. The proposed dock would be located a minimum of 25 feet inside the Crums' riparian rights lines. On December 6, 2005, the Department issued a Notice of Determination of Qualification for a Noticed General Permit for the revised dock, stating that the project satisfied the requirements of Florida Administrative Code Rule 62-341.427, as well as the conditions for authorization to perform activities on state-owned submerged lands set forth in Florida Administrative Code Rule 18-21 and for activities in an aquatic preserve under Florida Administrative Code Rule 18-20. In April 2006, Petitioners filed three petitions for hearing with the Department alleging that the proposed dock significantly impedes navigation by restricting access to a tidal creek and extends more waterward than necessary to access a water depth of (minus) -4 feet at mean low water, which is prohibited for docks in aquatic preserves under Florida Administrative Code Rule 18-20.005(3)(b)3. Petitioners attached to their petitions a copy of a bathymetric survey showing the elevations of the submerged lands in the vicinity of the proposed project. In response to the information contained in the survey, the Crums revised their plans to shorten the dock to its currently proposed length of 186.56 feet. A new Notice of Determination of Qualification for a Notice General Permit was then issued by the Department on October 16, 2006. The final dock project consists of: (a) removal of the existing wood dock; (b) construction of a four-foot wide, 186.56-foot long, single family residential dock consisting of an access pier, a 12-foot by 12-foot terminal platform, and a 14-foot by 20-foot open boat lift with catwalk (the “proposed dock”). The proposed dock will terminate where the water will be four feet deep at mean low water. Navigating in and Near the Tidal Creek To the south of the Crum property is a wide expanse of salt marsh. Within the salt marsh are unnamed tidal creeks. The mouth of one tidal creek that flows to Pumpkin Hill Creek is located approximately 90 feet south of the existing Crum dock. The tidal creek is shallow and is not navigable at or near low tide. Petitioner Jones owns an 18-foot flatboat which he sometimes keeps at his residence and sometimes at Petitioner Brooks' property. The boat draws about one foot of water. Petitioner Jones uses this boat to fish in the tidal creek located near the Crum property about ten times every month. No evidence was presented to show that Petitioner Brooks or Petitioner Cole ever navigate in or otherwise use this tidal creek. There are many other tidal creeks located in the marshes associated with Pumpkin Hill Creek. Petitioner Jones boats and fishes in most of them. Petitioner Jones said that, currently, he must wait two hours past low tide for the water depth to be sufficient for him to get into the tidal creek near the Crum property. His usual course to the creek lies just beyond the end of the existing Crum dock. He claims there is a channel there, but no channel is shown on the survey or in any of the parties' photographs. After the proposed dock is constructed, Petitioner Jones' usual course to the tidal will be obstructed. He contends that the new course he would have to take to the tidal creek will take him across shallower areas of Pumpkin Hill Creek so that he will have to wait two more hours (a total of four hours) after low tide to get into the creek. Therefore, Petitioner Jones' alleged injury is the reduction of the hours available to him to navigate in and out of the tidal creek for fishing. The existing Crum dock terminates on a broad mud flat which is exposed at mean low water. However, the bathymetric survey shows the mud flat is at a lower elevation near the end of the dock so water covers this area before it covers the rest of the mud flat. However, the bathymetric survey also shows the elevation of the bottom rising as one moves south from the existing dock. At the mouth of the tidal creek the elevation is 1.0 feet NGVD (National Geodetic Vertical Datum, an official, surveyed reference point). Because the tidal creek drains into the main body of Pumpkin Hill Creek, a reasonable inference can be made that the bottom elevations in the creek generally become higher (and the water depths decrease) as one moves up the creek toward dry land. Prop scars in the exposed bottom at the end of the existing dock indicate that boats have traveled over this area when the water was so shallow that the engine props were striking the bottom. Prop scarring can cause turbidity and damage to benthic organisms. The bathymetric survey indicates that mean high water in this area of Pumpkin Hill Creek is 3.03 feet NGVD, and the mean low water is -1.78 feet NGVD. The mean tidal fluctuation between mean low water and mean high water is thus 4.81 feet. Randall Armstrong, who was accepted as an expert in navigation and piloting, explained that in this area, where there are two daily tides, the water elevation will generally increase by 1/12 of the mean tidal fluctuation in the first hour after mean low water, another 2/12 of the fluctuation in the second, and 3/12 in the third hour. Applying this general rule to the tidal fluctuation here of 4.81 feet results in an estimated 1.2-foot increase in water elevation two hours after low tide and a 2.4-foot increase three hours after low tide. Based on the mean low water elevation of -1.78 feet NGVD, the water elevation would usually be about -0.6 foot NGVD two hours after low tide and 0.6 foot NGVD three hours after low tide. Therefore, the tidal creek (with a bottom elevation of 1.0 foot NGVD at the mouth) would usually be "dry" two hours after low tide and would usually have less than a foot of water three hours after low tide. That evidence contradicts Petitioner Jones' statement that he now navigates into the tidal creek two hours after low tide. That might occasionally be possible, but the bathymetric survey indicates the creek would usually be too shallow at that time. In fact, the evidence suggests that the tidal creek is only reliably navigable without causing prop scars to the bottom by using boats with very shallow draft and waiting until high tide (or shortly before or after) when the water depth at the mouth of the creek would be about two feet. It was Mr. Armstrong's opinion that the 1.0-foot NGVD elevation at the mouth of the tidal creek determines when and how long the tidal creek is navigable, and those times would not be affected by the proposed dock. He described the new course that a boater would use to navigate into the tidal creek after the proposed dock is built. He used the bathymetric survey to show that when the water is deep enough to navigate into the tidal creek, the water depth is also sufficient to navigate the new course. The proposed dock might, as Petitioner Jones alleges, cause boaters to traverse a longer section of the mudflat then they do currently. However, the more persuasive testimony supports the Crums' position that the navigability of the tidal creek is controlled by its shallowest point at the 1.0-foot NGVD elevation and that the proposed dock will not interfere with navigation of the tidal creek by requiring boaters to traverse shallower areas. Petitioner Jones testified that he regularly navigates his boat close to the existing Crum dock. The evidence does not indicate that the proposed dock would cause an unreasonable risk of collision for boaters using the new course to the tidal creek.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Secretary of the Florida Department of Environmental Protection enter a final order that grants Noticed General Permit No. 16-253057-002-EG to the Crums.

The Issue The issue is whether the Department should issue Environmental Resource Permit and Sovereign Submerged Lands Authorization No. 43-0197751-003 to Reily.
Findings Of Fact Parties The Department is the agency that approved the permit at issue in this proceeding. The Department is responsible for protecting the water resources of the state in conjunction with the water management districts, and it is also responsible for authorizing the use of sovereignty submerged lands pursuant to a delegation of authority from the Board of Trustees of the Internal Improvement Trust Fund. The activities authorized by the permit are as follows: The purpose of the project is to install a 395 linear foot upland retaining wall, with one 10 linear foot return, located at least 5-feet landward of the Mean High Water Line, and an 85 linear foot seawall, with one 10 linear foot return, located at the Mean High Water Line. Riprap shall be installed at a 2:1 (Horizontal:Vertical) slope along the 85 linear foot seawall, and will extend out a maximum of 4-feet waterward of the toe of the new seawall. [3] Reily is the applicant for the permit. Reily owns approximately 17.74 acres of property along Indian River Drive in Jensen Beach, just north of the Jensen Beach Causeway. The Reily property extends from the Indian River on the east to Skyline Drive on the west. Indian River Drive runs north and south through the east side of the property. The Reily property to the east of Indian River Drive is undeveloped except for an existing restaurant, Dena’s, which is on the southern end of the property. There is an existing “RV park” on the Reily property to the west of Indian River Drive. The project will be located to the east of Indian River Drive. That portion of the Reily property is approximately one acre in size, and is only 149 feet wide at its widest point. The property is 24 feet wide at its narrowest point, and more than half of the property is less than 68 feet wide. Petitioners live in single-family homes to the west of the Reily property. Each of their homes is within 300 feet of the Reily property to the west of Indian River Drive, but more than a quarter of a mile from the property on which the permitted activities will be located. Petitioner Anthony Parkinson sometimes drives by the property where the permitted activities will be located when he takes his daughter to school; he has had breakfast at Dena’s several times; he looks at the property from the causeway; and, on at least one occasion, he and his daughter looked at vegetation in the water adjacent to the Reily property for a school project. Mr. Parkinson testified that the project will negatively affect his quality of life because he “came to Jensen Beach because of the natural shoreline and the protection that it afforded to residents in terms of natural beauty” and that, in his view, the project “just adds to the incredible bulk that we have here in the property in terms of building in our natural shoreline.” Petitioner Michael Cilurso drives by the property where the permitted activities will be located on a fairly regular basis. He goes onto the property “occasionally” to “look around.” He has waded in the water adjacent to the property and has seen blue crabs, small fish, and underwater vegetation. Mr. Cilurso testified that the project will affect him in two ways: first, he will no longer be able to “go from the road and just walk down and wade around in [the river] and enjoy the natural resources;” and second, the proposed development of the overall Reily property will affect his “quality of life” because “the density [is] going to be more than what we thought would be a fit for our community.” Petitioner Thomas Fullman can see the Indian River from his house across the Reily property. He and his family have “spent time down at the causeway,” and they have “enjoyed the river immensely with all of its amenities” over the years. He is concerned that the project will affect his “quality of life” and “have effects on the environment and aquatic preserve [that he and his family] have learned to appreciate.” The Permit (1) Generally The permit authorizes the construction of an 85-foot- long seawall and a 395-foot-long retaining wall on the Reily property and the placement of riprap on the sovereignty submerged lands adjacent to the seawall. The seawall will be located on the mean high water line (MHWL). The riprap will be placed adjacent to the seawall, below the MHWL, and will consist of unconsolidated boulders, rocks, or clean concrete rubble with a diameter of 12 to 36 inches. The retaining wall will be located five feet landward of the MHWL, except in areas where there are mangroves landward of the MHWL. In those areas, the retaining wall will be located "landward of the mangroves". The permit does not require the retaining wall to be any particular distance landward of the mangroves or even outside of the mangrove canopy. The drawings attached to the permit show the retaining wall located under the mangrove canopy. The permit does not authorize any mangrove trimming. The areas landward of the seawall and retaining wall will be backfilled to the level of Indian River Drive. There will be swales and/or dry retention areas in the backfilled areas to capture storm water and/or direct it away from the river. The retaining wall will connect to an existing seawall on the Conchy Joe property immediately to the north of the Reily property. The seawall will connect to the approved, but not yet built seawall on the Dutcher property immediately to the south of the Reily property. The permit requires the use of erosion control devices and turbidity curtains during the construction of the walls in order to prevent violations of state water quality standards. (2) Permit Application and Review by the Department On or about June 23, 2005, Reily sought a determination from the Department that the seawall and retaining wall were not subject to the Department’s permitting jurisdiction. The project, as initially proposed, did not include the placement of riprap along the seawall. The Department informed Respondent in a letter dated October 11, 2005, that “the proposed seawall is within the Department’s jurisdiction.” The letter further stated that the Department was going to “begin processing [the] application as a standard general permit,” and it requested additional information from Reily regarding the project. The Department’s request for additional information (RAI) asked Reily to “justify the need for a seawall” and to “provide a detailed explanation” as to why the “use of vegetation and/or riprap is not feasible at the site” for shoreline stabilization. Reily responded as follows: Recent hurricanes have destroyed any vegetation that existed within the area of the proposed seawall. Shoreline has been lost and the DOT has had to backfill nearby upland areas and repair the roads due to significant erosion. The application is proposing to place riprap along the foot of the proposed seawall. There is no reason to believe that there will not be more storms in the near future and it is the applicants’ [sic] position that the seawall for this area is the only way to assure permanent shoreline stabilization and would be in the public’s best interest. The RAI also asked Reily to provide “a detailed statement describing the existing and proposed upland uses and activities.” (Emphasis in original). In response, Reily stated: “The existing upland use is an R.V. resort complex. The proposed use will remain the same.” The RAI also asked Reily to “provide details on the current condition of the shoreline at the site, including the location of mangroves and other wetland vegetation" and to "indicate if any impacts to these resources are proposed.” (Emphasis supplied). In response, Reily stated: “Please see plan view drawing sheet 2 of 4 that clearly shows that the proposed retaining wall will be located landward of the existing mangroves.” The sheet referenced in the response to the RAI does not show the location of wetland vegetation as requested by the Department. The referenced sheet is also inconsistent with other drawings submitted by Reily (e.g., sheet 3 of 4), which show that the proposed retaining wall will be located under the mangrove canopy, not landward of the existing mangroves. Reily’s response to the RAI was submitted on or about February 23, 2006. The Department gave notice of its intent to issue the permit on April 19, 2006. The permit included a number of general and specific conditions imposed by the Department. The permit states a petition challenging the issuance of the permit must be filed “within 14 days of publication of the notice or within 14 days of receipt of the written notice, whichever occurs first.” Notice of the Department’s intent to issue the permit was not published, and the record does not establish when Petitioners received written notice of the permit and the “notice of rights” contained therein. Mr. Cilurso acknowledged that he “found out about the DEP permit to Mr. Reily [approximately] six or eight months before [his] deposition in October [2006]” and then discussed it with the other Petitioners, but that testimony does not establish when the Petitioners received actual written notice of the permit. Petitioners’ challenge to the permit was filed with the Department on or about July 3, 2006. (3) The Related Pitchford’s Landing Project Contrary to the representation made by Reily to the Department during the permitting process, the evidence presented at the final hearing establishes that Reily is proposing to change the use of the upland property from an RV park to a residential development known as Pitchford’s Landing. A master site plan for the Pitchford’s Landing development was submitted to Martin County for approval in April 2006. The site plan (Pet. Ex. 10) shows extensive residential development to the west of Indian River Drive, including single- family lots and multi-story condominium buildings; construction of a sidewalk, bike path, pool, cabana, public pier, and riverwalk to the east of Indian River Drive; the refurbishment of Dena’s restaurant; and the "proposed seawall." Petitioners were aware that the plans for Pitchford’s Landing included a seawall by April 2006, but the evidence was not persuasive that they had received written notice of the Department’s intent to issue the permit at that time. The Pitchford’s Landing development will require changes to the land use designation of the Reily property in the Martin County Comprehensive Plan as well as zoning changes. Those local approvals had not been obtained as of the date of the final hearing. The plans for the Pitchford’s Landing development are being revised based, at least in part, on opposition from Petitioners and others involved in an “association” known as The Jensen Beach Group. Petitioners Cilurso and Fuller are active members of the group, and Petitioner Parkinson has also participated in the group’s activities. Bruce Jerner, one of Reily’s consultants, testified to his understanding that the pool, cabana, and riverwalk shown on the master site plan are being removed from the Pitchford’s Landing development. However, there is no evidence to suggest that the Reily property to the east of Indian River Drive and/or the other improvements on that property (including the hardened shoreline authorized by the permit) are being removed from the Pichford’s Landing develoment. The more persuasive evidence establishes that the proposed seawall, retaining wall, and riprap are part of the larger Pitchford’s Landing development. The walls were referred to on the master site plan for the development; they were depicted and discussed in an advertising brochure as an amenity of the development; and signs advertising Pitchford’s Landing are located on the Reily property to the east of Indian River Drive on which the seawall and retaining wall will be located. There is no evidence that the Pitchford’s Landing development has received a permit from SFWMD under Part IV of Chapter 373, Florida Statutes. The master site plan for Pitchford’s Landing shows several “dry retention areas” to the west of Indian River Drive, and as noted above, there will be swales and/or dry retention areas in the backfilled areas behind the retaining wall and seawall to capture storm water and/or direct it away from the river. It cannot be inferred from that evidence alone, however, that the Pitchford’s Landing development will require permits from SFWMD under Part IV of Chapter 373, Florida Statutes. Merits of the Project The Indian River in the vicinity of the Reily property is a Class III waterbody, an outstanding Florida water (OFW), and part of the Jensen Beach to Jupiter Inlet Aquatic Preserve. The Jensen Beach to Jupiter Inlet Aquatic Preserve is one of three aquatic preserves that encompass the Indian River Lagoon system that extends from Vero Beach to Jupiter Inlet. The Jensen Beach to Jupiter Inlet Aquatic Preserve is 37 miles long and encompasses approximately 22,000 acres of surface water area. The entire Indian River Lagoon system is 49 miles long, with approximately 33,000 acres of surface water area. The Management Plan that was adopted for the Jensen Beach to Jupiter Inlet Aquatic Preserve in January 1985 described the Indian River Lagoon system, and explained its ecological importance as follows: The Indian River Lagoon area is a long, shallow lagoonal estuary important in this region for its value to recreational and commercial fishing, boating and prime residential development. The preserve is in a rapidly growing urban area affected by agriculture and residential drainage. The majority of the shoreline is mangrove fringed, with scattered development in single family residences and a few condominiums. The lagoon is bounded on the west by the Florida mainland and on the east by barrier islands. The Intracoastal Waterway runs the length of the lagoon, which is designated as a wilderness preserve. The estuary is an important home and nursery area for an extensive array of fish and wildlife. The major problems in the continued health of this area include the construction of major drainage networks that have increased the fresh water flow into the estuary, and the loss of wetland areas and water quality degradation associated with agricultural drainage and urban runoff. Additionally, the Intracoastal Waterway and the maintained inlets have changed the historical flushing and circulation within the lagoon system. The Management Plan explained that the “major objectives of the aquatic preserve management program are to manage the preserve to ensure the maintenance of an essentially natural condition, and to restore and enhance those conditions which are not in a natural condition.” The Management Plan recognizes “the rightful traditional uses of those near-shore sovereignty lands lying adjacent to upland properties,” and with respect to bulkheads, the Management Plan states: Bulkheads should be placed, when allowed, in such a way as to be the least destructive and disruptive to the vegetation and other resource factors in each area. Approved uses which do destruct or destroy resources on state-owned lands will require mitigation. The mitigation will include restoration by the applicant or other remedy which will compensate for the loss of the affected resource to the aquatic preserve. Most of the shoreline along the Reily property is a gently sloping sandy beach that has been previously disturbed, and is largely barren of vegetation. There are, however, areas along the shoreline where dense vegetation exists, including wetland vegetation and three stands of mature red and black mangroves. Birds, fish, and wildlife have been observed on and around the Reily property. However, there is no credible evidence that any listed species use the uplands or near-shore waters where the project will be located. The sovereignty submerged lands immediately adjacent to the Reily property on which the riprap will be placed are barren, sandy, and silty. There are seagrasses in the vicinity of the Reily property, but they are 30 to 50 feet from the shoreline. The seagrasses include Johnson’s seagrass, which is a listed species. There are no significant historical or archeological resources in the vicinity of the Reily property, according to the Department of State, Division of Historical Resources. In 2004, Hurricanes Frances and Jean made landfall in Martin County in the vicinity of the Reily property. The hurricanes washed out portions of Indian River Drive, including a portion of the road approximately one-half mile north of the Reily property. After the hurricanes, Martin County considered placing bulkhead along the entire length of Indian River Drive to provide shoreline stabilization and to prevent further damage to the road in major storm events. The county did not pursue the plan because it determined that it was not financially feasible. The portion of Indian River Drive along the Reily property did not wash out during the 2004 hurricanes. Nevertheless, on November 4, 2004, because of concerns for the stability of the shoreline along the Reily property, the Department issued an Emergency Field Authorization to the prior owner of the property allowing the installation of 160 linear feet of riprap along the shoreline. The riprip authorized by the Emergency Field Authorization was to be placed considerably further landward than the structures authorized by the permit at issue in this case. The record does not reflect why the riprap was not installed. The evidence was not persuasive that the Reily property has experienced significant erosion or that the project is necessary to protect Indian River Drive or the upland property from erosion. The project will, however, have those beneficial effects. No formal wetland delineation was done in the areas landward of the MHWL or the areas that will be backfilled behind the proposed seawall and retaining wall and, as noted above, Reily did not identify the location of wetland vegetation and any impacts to such vegetation in response to the RAI. Mr. Jerner testified that, in his opinion, there are no wetlands landward of the MHWL in the area of the seawall, and that any wetlands in the area of the retaining wall are waterward of that wall, which will be at least five feet landward of the MHWL. The Department’s witness, Jennifer Smith, testified that it was her understanding that the wetlands did not extend into the areas behind the seawall or retaining walls, but she acknowledged that she did not ground-truth the wetland boundaries and that wetland vegetation appeared to extend into areas that will be backfilled. Petitioners’ expert, James Egan, testified that the wetlands likely extended into areas that will be backfilled based upon the topography of the shoreline and the wetland vegetation that he observed, but he made no effort to delineate the extent of the wetlands in those areas and he testified that he would defer to the Department's wetland delineation if one had been done. The Department’s wetland delineation rules in Florida Administrative Code Rule Chapter 62-340 contain a detailed quantitative methodology to be used in making formal wetland boundary delineations. That methodology is to be used only where the wetland boundaries cannot be delineated through a visual on-site inspection (with particular attention to the vegetative communities and soil conditions) or aerial photointerpretation in combination with ground truthing. Thus, the Department’s failure to do a formal wetland delineation (with soil sampling, etc.) in the project area was not per se inappropriate, as Mr. Egan seemed to suggest. That said, the more persuasive evidence fails to establish that Reily made an appropriate effort to delineate the landward extent of the wetlands in the project area. No delineation of the wetland areas was provided in response to the RAI, and Ms. Smith’s testimony raises more questions than it answers regarding the correctness of Mr. Jerner’s conclusory opinion that the wetland boundary is waterward of the retaining wall. Without an appropriate delineation of the wetland boundaries, it cannot be determined with certainty whether or not there are wetlands in the areas that will be backfilled. The evidence establishes there may be wetlands in those areas; and if there are, the impacts to those wetlands have not been assessed or mitigated. Riprap is a better method of shoreline stabilization than a vertical seawall without riprap. The riprap helps to prevent shoaling by absorbing wave energy, and it also provides habitat for benthic organisms, crustaceans, and small fish. Native vegetation provides these same benefits, and all of the experts agreed that it is the best method of shoreline stabilization from an environmental standpoint. The use of native vegetation to provide shoreline stabilization along the Reily property is not a reasonable alternative under the circumstances. First, the shoreline has not experienced any significant vegetative recruitment since the 2004 hurricanes. Second, the property is not wide enough to accommodate the amount of vegetation that would be needed to stabilize the shoreline. Third, the properties immediately to the north and south of the Reily property are already (or soon will be) protected by seawalls and/or riprap, rather than native vegetation. The project will not adversely affect the property of others. The evidence was not persuasive that the project will cause erosion or other impacts to the adjacent properties, particularly since the adjacent properties have, or soon will have hardened shorelines. The project will not adversely affect the conservation of fish and wildlife and, to the contrary, the riprap will provide a benefit to fish and wildlife by providing shelter and habitat for benthic organisms, crustaceans, and small fish. The project will not adversely affect endangered or threatened species or their habitat. The only listed species shown to exist in the vicinity of the project, Johnson’s seagrass, is 30 to 50 feet from the shoreline, which is too far away from the project to be affected even if, as suggested by Petitioners' experts, the impact of wave energy on the walls will cause increased turbidity and sedimentation. The project will not adversely impact the fishing or recreational values or marine productivity in the area. The waters in the vicinity of the project are not shellfish harvesting areas, and the riprap will provide beneficial habitat for small marine life. The project will not adversely affect navigation. The riprap will extend only four feet into the Indian River in an area of shallow water far from the channel of the river. The project will not cause harmful erosion or shoaling or adversely affect water quality in the area. The evidence was not persuasive that wave energy will routinely impact the retaining wall to an extent that will cause increased turbidity or sedimentation in the surrounding waters, and all of the experts agreed that the riprap will help to prevent this from occurring along the seawall. Moreover, the swales and/or dry retention areas behind the seawall and retaining wall will help to filter storm water runoff from Indian River Drive and the adjacent upland properties, which may enhance the water quality in the vicinity of the project. The project will not result in any adverse secondary or cumulative impacts to the water resources. The adjacent properties already have hardened shorelines. The permit conditions include adequate safeguards (e.g., turbidity curtains and erosion control devices) to protect the water resources in the aquatic preserve during construction of the project. Any impact (either positive or negative) of the project on the aquatic preserve and the Indian River Lagoon system as a whole will be de minimus in light of size of the system in comparison to the small size of the project and its location between two hardened shorelines near a man-made causeway.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department issue a final order dismissing Petitioners’ challenge to the permit/authorization for a lack of standing, but if the Department determines that Petitioners have standing, it should issue a final order denying permit/authorization No. 43-017751-003 absent an additional condition requiring an appropriate wetland delineation to show that the upland aspects of the project will occur outside of the mangrove canopy and any other wetland areas landward of the MHWL. DONE AND ENTERED this 12th day of February, 2007, in Tallahassee, Leon County, Florida. S T. KENT WETHERELL, II Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 12th day of February, 2007.
Findings Of Fact The Petitioner has an option to purchase property located at 301-307 Island Way Boulevard, Island Estate, Clearwater, Florida, on which he proposes to construct ten townhouses. Initially Petitioner asked for two variances. The first variance was for 25.12 feet to allow construction on a lot only 124.88 feet wide. This variance was granted for this nonconforming lot. The second variance, for 13.24 feet to allow construction of the ten townhouse complex 12 feet from the side property line, was denied by the Clearwater Code Adjustment Board. The Board concluded the variance requested did not meet the requirements of Section 45.24 of the Clearwater Land Development Code. Petitioner presented evidence that if the lot had been 150 feet wide they would have had 90 feet to build on without requesting any variance. However, since the lot was nonconforming, in order to have 89 feet on which to place the building, the requested variance would be necessary. Petitioner also presented evidence that the construction of ten townhouses on this lot is necessary for the project to be on a solid economic basis. Subsequent to the denial of this variance by the Development Code Adjustment Board, Petitioner submitted plans, which have been approved by the City of Clearwater, to erect nine townhouses on this property without any variance needed. However, these townhouses would be smaller than would be the ten townhouses initially proposed and would provide a lesser return on the capital invested.
Findings Of Fact Permitting History This development was originally known as North Largo Yacht Club and was owned and developed originally by the Largo Brand Corporation. That developer and this development received Development of Regional Impact approval from the county commission of Monroe County in accordance with Chapter 380, Florida Statutes in 1974. In 1975 that developer received various permits and water quality certifications authorizing construction of the "Atlantic Marina" (the existing marina) from both the Florida Board of Trustees of the Internal Improvement Trust Fund and the United States Army Corps of Engineers. The marina was ultimately constructed and no further governmental approvals are required for the present Respondents to make full use of the existing marina which has an authorized boat capacity of 363 boat slips, which are situated around long piers extending from the shore of the marina basin out into the marina basin. Sometime after construction of the marina, the mortgagee, through foreclosure, obtained title to the property from Largo Brand Corporation which has since dissolved, ultimately conveying it to City National Bank as trustee under a Florida land trust. City National Bank filed the present application in its original form but in February, 1984, conveyed the property to Port Bougainville, Inc. and Port Bougainville Enterprises, Inc., the present Applicant/Respondent who succeeded City National Bank as the real parties in interest prosecuting the present permit application, as modified. The permit application as it presently exists is the result of various modifications suggested by the Department of Environmental Regulation and agreed to by the present Applicant/Respondents, which had the effect of causing the Department to change its position from one of denial of the permit to one of approval, by issuance of a Notice of Intent to grant the permit in June of 1984. The Applicant/Respondent's original decision to apply for the new permit was based upon aesthetic considerations and a desire to redesign and change the theme of the development and the marina itself. It is thus proposed that the boat-mooring facilities be moved to the periphery of the basin and the piers or docks extending out into the basin be removed. This would create an open body of water in the basin, more in keeping with the "Mediterranean Village Harbor" theme of the entire development. The original application filed in early 1984, called for realignment of the docks rather than removal, and the creation of various baylets or inlets along the access canal and contained no proposal for shoaling the existing boat basin. The Department used this original proposal as a basis for its Intent to Deny the Permit Application since it considered those modifications unacceptable in terms of the likelihood that it might degrade water quality or at least not improve the ambient water quality then existing in the marina basin and entrance canal. The Respondents acceded to the demands of the Department, employed additional consultants and redesigned the project, including the creation of a sophisticated hydrographic model by which, and through which, the Respondents ultimately proposed (with the Department's agreement) to revise the application as follows: Shoal the entire basin and canal system to no more than -6 Ft. mean low water; widen and sculpt the access canal on the west side and install solid flow baffles on the east side so as to create a sinusoidal or curving configuration in the canal to improve mixing of the water in the canal and basin system; remove the existing docks and construct new docks around the periphery of the basin so as to provide a decreased number of boat slips and capacity for a total of 311 boats; install one bubble screen surrounding the fueling facilities to contain oil and fuel spills and another at the entrance of the access canal where it opens into the Garden Cove Channel so as to prevent organic materials from outside the canal and basin system from being carried into it with tidal currents and wind; installation of "batter boards" along the length of the waterward or easterly and southeasterly side of the access canal so as to protect the mangroves along that side of the canal from the effects of wake energy caused by boats. After further "free-form" review, investigation and negotiation, the Department required, and the Respondents agreed to make the following additional modifications to the marina development plan: Shoal the north end of the basin to -4 ft. mean low water; slightly reconfigure the access canal and install an additional wave baffle on the eastern periphery of the canal in order to improve circulation in the western portion of the boat basin; relocate the proposed fueling facilities more toward the rearward center of the basin in order to further isolate them from the outstanding Florida waters lying at the outward, "seaward" end of the project; provide funds necessary to more adequately mark the Garden Cove Channel in accordance with the requirements specified by the Department of Natural Resources so as to further ensure that boat traffic and possible propeller damage could be prevented to the marine grassbeds and other marine life on either side of the Garden Cove Channel; install tidal level gauges at the mouth of the Garden Cove Channel which would show boaters wishing to use the channel and access canal the current, minimum depths prevalent in the channel and canal; grant to the Department a "conservation easement" binding upon the Respondent which would provide the following: That no hydraulic connection be made from any of the upland lakes on the Respondent's property to the marina, to the canal, to the channel or any other state waters; an agreement not to employ boat lifts that would require a dredge and fill permit from the Department; an agreement not to apply for additional permits so as to increase the number of boat slips in the marina beyond the 311 presently proposed; to develop a reef management plan in conjunction with the Florida Audubon Society to include educational programs for the public as well as underwriting the installation of mooring buoys and adequate channel markers in the John Pennekamp Reef Park, the Outstanding Florida Waters (OFW) involved in this proceeding. During the time of construction of the proposed marina modifications, the entire marina will be closed and isolated from the waters of Garden Cove by the installation of a dam at the entrance to the marina access canal where it opens into Garden Cove. The dam will remain in place until turbidity resulting from the dredging, filling and construction has settled and the waters in the marina have achieved the turbidity standards required by the Department and its rules contained in Chapter 17 3, Florida Administrative Code. All the proposed modification work will be performed landward of the surveyed mean high water line. Additionally, a storm drainage system will be installed which will prevent any stormwater runoff from being deposited into the marina harbor. The stormwater runoff will be routed away from the harbor through the use of a reverse gradient around the periphery of the harbor and runoff from the adjacent real estate development will be thus routed away from the harbor into grass swales to be collected into holding areas for filtration. Ambient Water Quality in the Marina and Garden Cove Respondents tendered Dr. Earl Rich, a professor of Biology at the University of Miami as an expert in ecology and he was accepted without objection. Since 1974 he has conducted extensive studies with attendant sampling, observation and water quality monitoring in the Port Bougainville Marina. Beginning in 1983 he also performed certain chemical analyses on the water samples from the marina. Photographs taken underwater in the marina basin were adduced and placed in evidence, as were the results of the observations and tests. It was thus established that there is a dense growth of macroalgae in the marina at a depth of about six feet, although at the nine-foot level there is much less such growth. Concomitantly, the deeper holes in the marina basin exhibit a low dissolved oxygen reading and are largely responsible for the frequently occurring, low dissolved oxygen reading in the marina system that is lower than acceptable standards embodied in Chapter 17-3, Florida Administrative Code. Garden Cove itself is a shallow embayment open toward the Atlantic Ocean in a generally easterly direction, characterized by a rocky or coarse sediment bottom substrate. It is characteristic of this area that organic materials such as seaweeds and the like, are transported by currents and winds into Garden Cove from other marine areas. The underwater vegetation in Garden Cove is lush. There are extensive shallow-water marine grass beds. These vegetated areas support a large population of marine animals and fish. Dissolved oxygen is, of course, essential to the metabolism of these organisms. The two primary means for oxygen to enter the water are as a result of photosynthetic activity of marine plants and through oxygen entering the surface waters through waves and wind action, with that surface water being distributed and mixed so as to disburse the action throughout the water column. The term biochemical oxygen demand or BOD, refers to the rate at which organisms use oxygen in the water. If there are many active photosynthetic organisms, as in Garden Cove, the production of oxygen during the day, as for instance by the seagrasses in the cove, exceeds the BOD of the plant and animal community in the water body, in which case the plants contribute excess oxygen to the air. During hours of darkness, plant and animal communities in the water body will continue to consume oxygen although there will be no photosynthesis to contribute oxygen. Therefore, in an underwater community rich in plant and animal life, such as Garden Cove, the dissolved oxygen level is typically higher during the daylight hours and BOD readings will be decreased during the night, reaching a low level during the early morning hours. Frequently, dissolved oxygen readings in Garden Cove are below state standards for waters of the State under natural conditions. These low DO readings occur commonly in Garden Cove during conditions of calm wind. Indeed, Dr. Rich has measured dissolved oxygen in Garden Cove below the four-part per million state standard even before the present marina and canal were ever constructed. Since the opening of the marina there have been times when the DO readings in Garden Cove have been lower than those inside the marina itself. Hydrodynamics of the Modified Marina The proposal by the permit applicant calls for widening the access channel into the marina to approximately 130 feet by excavating upland on the western bank of the canal. The access canal will then be reconfigured during the excavation into a winding or curving fashion. That adjustment, along with the solid flow baffles to be installed on the eastern bank of the canal, will set up a winding or sinusoidal flow of tidal currents. The sinusoidal flow will induce secondary helical currents that will move water repeatedly from the top to the bottom of the canal and then back, thereby significantly improving the mixing action. The improved mixing of the waters in the canal and marina will serve two purposes: It will disperse any pollutants so as to reduce pollutant concentrations. It will disperse the oxygen introduced into the surface waters by wave and wind throughout the water column. Dr. Bent Christensen is Chairman of the University of Florida Hydraulics Lab. Using knowledge gained in hydrographic modeling as a result of work he performed in carrying out a "Sea Grant study" under the auspices of the University of Florida, Dr. Christensen designed a computer model of the proposed Port Bougainville marina and access canal by which, in turn, he designed the winding access canal which will emulate nature in producing a turnover of water induced by current velocities and canal configuration, rather than by temperature differences in water. The computer model takes into account tidal flows and wind-induced velocities which are important to mixing of water within the system. Using this model, Dr. Christensen was able to redesign the marina canal so as to improve water quality within that system as well as improving the quality of water leaving the system into Garden Cove. Drs. Lee and Van de Kreeke are ocean engineers who testified as expert witnesses on behalf of Petitioners. They sought to dispute Dr. Christensen's conclusion that the redesign would improve DO levels within the marina based upon their independent determination that a different design would increase flushing times for the system. Flushing, however, is a simplistic way of analyzing water quality. Flushing analysis assumes that the only means to improve water quality is to replace water within the system with water from outside the system. The Christensen model and the resulting proposed design of the marina and canal, on the other hand, improves water quality through internal mixing action. The proposed design actually reduces flushing time, but more importantly, maximizes dispersion of water within the system and along with it, dissolved oxygen. The design introduces dissolved oxygen throughout the water column in the system through internal mixing because of the sinusoidal configuration of the canal and the helical currents the canal configuration sets up. The concentration of pollutants measured by the State Water Quality Standards are, in turn, reduced through the same hydrodynamics. Dr. Van de Kreeke admitted that a key ingredient in his model was the assumption he had regarding BOD in the system, but he had no idea what the BOD extant in the Port Bougainville system might be. He also admitted that his calculations did not take into consideration the factor of wind mixing of the waters in the system and acknowledged that wind can and does play an important role in flushing and mixing the waters in marinas. Finally, Dr. Van de Kreeke admitted that he could not fully analyze Dr. Christensen's assumptions in arriving at his model and design because he did not have the information Dr. Christensen relied upon. Thus, Dr. Christensen's model and design is accepted as more credible than that of Drs. Van de Kreeke and Lee. That model and design establishes that the quality of water exiting the marina into the Outstanding Florida Waters in Garden Cove will be improved by the modifications proposed to be constructed in the marina. Impact on Benthic Communities The northerly end of the marina basin will be sloped from -6 feet to - 4 feet. This widening and shallowing of the marina basin and access channel will have the affect of promoting the growth, regrowth and welfare of the benthic communities in the waters in the marina and access canal by providing greater light penetration to the bottom of the marina. The widening will have the effect of causing a greater portion of the marina bottom to be lighted during the day since at the present time, the bank and surrounding trees shade the marina basin for substantial portions of the day. The increased light penetration will result in more photosynthetic activity by the plant life in the marina and canal such that increased amounts of oxygen will be produced enhancing the dissolved oxygen levels of the marina waters. In that connection, the Respondents' expert, Dr. Rich, has examined a number of marinas and observed very healthy benthic communities in marina harbors more densely populated with boats than will be the proposed marina. Another significant improvement in the ecological status of the present marina will be the placing of a bubble screen device across the mouth of the entrance canal. This will have the effect of preventing floating organic materials such as sargassum, from entering the marina. Marinas typically experience problems related to dissolved oxygen levels in their waters because of an accumulation of floating organic material which tends to settle to the bottom creating excessive biochemical oxygen demand in their decomposition process, thus resulting in decreased dissolved oxygen levels. Thus, the bubble screen will aide in decreasing BOD. Likewise, a bubble screen device is proposed to be placed around the fueling facilities in the rearward portion of the marina basin so as to prevent the spread of pollutants such as spilled oils, greases and fuels, which may occur during routine fueling operations from time to time. Inasmuch as the modifications have been shown to cause some improvement in the dissolved oxygen level in the waters of the marina basin and access canal, it has been demonstrated that the modifications will not interfere with the conservation of marine wildlife and other natural resources. The bodies of water consisting of the marina, the access canal and Garden Cove, at the present time support a diverse marine community that can be expected to continue to flourish. Neither will the proposed activity destroy any oyster or clam beds, as none have been shown to exist in these waters. Dr. Rich has monitored waterways and offshore waters at a nearby, comparable marina, The Ocean Reef Club, for approximately ten years. He has discerned no noticeable impact on the benthic communities within that marina from a very heavy boat traffic during that period of time. The boats using The Ocean Reef Club Marina are typically larger than will use the Port Bougainville facility and boats of over 100 feet in length commonly use The Ocean Reef Club. In terms of impact on offshore benthic communities, he has observed no visible impact by the heavy amount of boat traffic using The Ocean Reef Marina from the standpoint of comparison of the experience with that marina, in terms of biological impacts, with the marina configuration proposed by the Applicant/Respondents. In short, the proposed marina configuration as contrasted to the existing permitted marina, represents an improvement because of the increased surface area providing increased oxygen exchange through wave and wind action, the shoaling which will also be beneficial to dissolved oxygen levels because of its enhancement of photosynthetic processes, and because of the proposed marina management steps designed to prevent floating organic material from entering the marina. Thus, the modified design was shown to provide a meaningful improvement in general ecological conditions within the marina and hence, in the offshore waters of Garden Cove with which the marina waters exchange and mix. Water Quality Dr. Eugene Corcoran is Professor Emeritus of the Rosensteel School of Marine and Atmospheric Sciences. He is a marine chemist and performed a chemical analyses of the samples taken for the water quality report presented by Respondents and in evidence as Respondent's Exhibit 17. Dr. Corcoran also performed the analyses for the ongoing water sampling program conducted by Dr. Renate Skinner, an expert witness for Petitioners. The Petitioners accepted Dr. Corcoran as an expert witness without objection. The proposed marina modifications involved in this permitting application were thus shown to cause no violations of the state standards for dissolved oxygen. The Rio Palenque Water Quality Study in evidence indeed documented a number of instances where dissolved oxygen fell below the state minimum standards of four parts per million in the present marina. Once the modifications are completed there still may be instances when dissolved oxygen falls below that standard, but this can be attributed to natural phenomenon and the same relatively low levels of dissolved oxygen below state standards have been observed in the offshore waters of Garden Cove itself, which is an Outstanding Florida Water. Significantly, however, it was established that concentrations of dissolved oxygen will likely increase as a result of these modifications, the inducement of the helical flow and consequent vertical mixing, the widening of the entrance canal and the shoaling of the bottoms in the marina basin and canal, as well as the measures to be taken to reduce the deposition of organic materials in the marina basin and canal. The only water quality criteria placed in contention by the Petitioners and Intervenors were dissolved oxygen and copper. Although a number of Petitioners' witnesses were qualified to address the impacts of water quality on different marine organisms, only Dr. Curry was qualified as an expert in water quality. Dr. Curry's chief concern was with dissolved oxygen, which is based on the Rio Palenque Study showing present low values for dissolved oxygen in the marina as it now exists. Dr. Curry did not establish that the proposed modifications to the marina would themselves cause dissolved oxygen violations and although he testified in great detail concerning his attempt to compute the amount of copper that might be given off by the bottom paint of boats in the modified marina, he was unable to render an opinion that the modifications would increase copper levels in the waters in the marina. He acknowledged that his calculations were based on the assumption that all the boats in the marina would be using copper anti-fouling paints and his calculations took into account an assumption that all boats in the marina would have been painted within the last six months as a base datum for his calculations. Additionally, he did not take into account dispersion ratio associated with the hydrodynamic forces present in the modified marina. Dr. Curry admitted that he had never studied copper levels in a marina environment and was unable to explain the chemical effects on water quality of copper anti-fouling paints on boats. In all his sampling, he only found one instance of a violation of the Chapter 17-3 copper standard and that occurred within only a few millimeters of the hull of a newly-painted boat. Other fallacies involved in Dr. Curry's analysis, concern the interaction of seawater with copper bottom paint. Since seawater has a high level of carbonates, copper is immediately complexed with organic compounds such as amino acids. These organic complexes are soluble in seawater and indeed, serve as important nutrients to phytoplankton and other beneficial marine organisms. Thus, that portion of the total complex copper precipitated from the water as well as that portion taken up as nutrients would not be included in any concentrations of copper measured in the water column. Additionally, Dr. Curry's computations did not take into account the dispersion of copper concentrations due to mixing or flushing, which has a direct beneficial effect on reducing concentration of copper and other pollutants in the water column. Thus, Dr. Curry's computations are deemed immaterial, inasmuch as he effectively admits that the modifications to the marina would not be detrimental to water quality. The proposed modifications will not lower ambient water quality or significantly degrade the waters in the adjacent John Pennekamp Park, Outstanding Florida Waters. Since it has been established that the marina modifications will likely improve water quality within the marina, logically, the water quality in the park to some degree might be slightly improved, since those waters exchange with the waters in the marina. There will be no increase in concentrations of any pollutants emanating from the Port Bougainville Marina as a result of the proposed modifications. Improved Marking of Garden Cove Channel The Applicant/Respondents are required to provide improved navigational markers in the Garden Cove Channel, pursuant to an amended development order. Additionally, they have agreed to provide additional channel markers delineating the channel from the entrance of the existing marina to the Garden Cove Channel proper. With regard to the Garden Cove Channel, the Respondents proposed to move certain existing channel markers to more clearly identify that channel, which would make certain portions narrower and thereby eliminate boat passage over some shallow areas populated with marine grasses which presently lie within the marked channel. The Respondents also propose to add two more sets of channel markers at the seaward end of Garden Cove Channel, so that boats exiting the channel heading for the open sea will avoid certain shallow marine grass areas. The reason for this is to avoid possible damage to valuable marine grass beds and habitat which might be caused by prop wash of boats crossing over them, as well as actual contact and scouring by propellers or potential grounding of boats navigating these areas. Witness Balfe for the Respondents has personally sounded the entire length of the access canal and Garden Cove Channel. His soundings are admitted in evidence as Respondent's Exhibit 19 and are unrefuted. It was established therefore, that the bottom configuration of that access channel is basically flat or level with only minor irregularities of less than a foot. There are no rock outcroppings or other obstructions which would reduce the controlling depth below -4 feet. Approximately 12 times per year however, during "spring tides", the ambient water depths in Garden Cove could be expected to go below -4 feet mean low water. During these times the tide will be approximately 6 to 8 inches below that normal depth. Perhaps 25 times per year the tide is 5 or 6 inches below that mean low depth. The tide gauge which will be installed will alleviate possible propeller scouring or grounding damage to grass beds and marine habitat, especially during those abnormally low tides, by providing boat operators a current, up-to-date reading on the depths in the channel. Contributions to Park Management Plan and Marina Management Plan The Applicant/Respondents have agreed to a permit condition requiring a financial commitment to assist in the management of the John Pennekamp Park so as to minimize the adverse impacts of human use of the park. This commitment includes the provision of $75,000 to finance a study and preparation of a management plan for the John Pennekamp Coral Reef State Park and Key Largo National Marine Sanctuary, which would include study of the feasibility of inaugurating an entry permit system for the park, a testing and certification program for commercial dive boat operators, possible zoning of the park to allow recovery of the park coral reefs and other resources from the impacts of human visitors, locating central mooring buoys so that visitors' boats could be moored in one restricted area to avoid damage to the delicate coral reefs, and more adequately marking the boundaries of the park. Additionally, the Respondents propose to provide $50,000 for the acquisition of anchor buoys to be placed in selected areas of the park and to provide funds to finance a survey to more adequately identify the boundaries of the park. In order to more adequately protect water quality in the marina itself, the Respondents will inaugurate a marina management program which will include the installation of a sewage pump-out station and a pump-out station for motor oils and lubricants for boats. In addition to the two bubble curtains mentioned above, the Respondents will install containment booms and absorption mats and will permanently maintain a boat equipped with absorption mats and suction equipment for fuel or oil spill removal. The marina will prohibit persons living aboard boats, to prevent attendant sewage effluent problems, and will prohibit maintenance of boats, including painting and oil changes, while boats are in the water. This program will be monitored by an environmental protection officer employed by the condominium association under the auspices of the Respondents. Many of these marina management provisions are already requirements of the Port Bougainville 1982 development order referenced above. Management of Inland Lakes Although the use and management of the inland lakes on the Respondents' property is not directly involved in this permit application proceeding, the Respondents' overall development plan encompassed by the development order anticipates that at a future time a boat lift will be installed on upland so as to allow boats to be transferred from the inland lakes into the marina for access to marine waters. The lakes themselves, however, will not be open to the marina or to outside waters. The inland lakes are anticipated to provide dockage for approximately 200 boats, with restrictions against boats exceeding 20 feet in length and boats powered by combustion engines. The Respondents expect that the inland lakes will be primarily used by small boats such as canoes or sailboats. Dry storage for boats will be maintained on an upland site, for which a DER permit is not required. Neither is a permit for a boat transfer facility required since it would not involve dredging, filling or construction over water. The use of a boat lift, although it itself is not an issue before the Hearing Officer in this proceeding, would involve the potential of 200 or more boats using the marina in addition to those for which the marina is designed. This could occasion substantially greater risk for oil, grease and fuel spills and other potential damage to the water quality within the marina and damage to the marine habitat, grass beds and so forth within the marina, the access canal and the adjacent areas in Garden Cove. Accordingly, the conservation easement which the Respondents have agreed to provide the department as a condition to the grant of this permit should be amended to add a further condition on a grant of this permit so as to preclude placement of boats from the inland lakes into this marina or its access canal. Such a restriction would comport with the proposed uses of the inland lakes established by Mr. Scharenberg, the Respondent's principal. Boating Impacts Boat traffic in the Garden Cove Channel area is significant, with heaviest traffic occurring on the weekends when approximately two to three hundred boats navigate that channel. The boats presently using Garden Cove Channel come from a number of nearby marinas, small fishing docks and dry storage areas, as well as from a marked navigational channel called North Creek that provides access to the Garden Cove area and the Atlantic Ocean from Largo Sound. A small canal cuts through Key Largo into Largo Sound and provides access for boats in the Black Water Sound and other areas on the west side of Key Largo to the Garden Cove area and the Atlantic. The Port Bougainville Marina is expected to attract a mix of boats typical for such a marina, with the majority consisting of boats ranging from 27 to 35 feet in length. Approximately 20 percent of the boats will likely be in the 40-foot range. Larger boats may also use the marina, particularly those with a shallow draft, and "shoal draft" sailboats of 35 to 40 feet can safely navigate in and out of the marina. The marina, as it would be modified, would permit use of boats with a draft of up to three and one-half feet, although deeper draft boats could use the marina by timing arrivals and departures for the high tide, which is a common mode of operation by boat operators in the Florida Keys and other marine areas. The Port Bougainville Marina will contribute approximately 30 to 50 boats to the Garden Cove boat traffic on an average weekend out of the possible 311 boats in the harbor as it is proposed to be constructed. There will be a lesser number of boat arrivals and departures during the weekdays. The primary users of boats in and out of the marina will be people who own condominiums in the attendant real estate development. Temporary visitors, not owning boats moored in the marina, would typically use the dive charter boats and other rental boats in the surrounding areas, such as at the Ocean Reef facility. The existing marina which is already permitted and can be fully used at the present time from a legal standpoint, could accommodate the same reduced number and sizes of boats as the proposed modified marina by simply removing some of the present docks and finger piers. The Respondents propose to maintain approximately 20 slips for boats which are not owned by condominium unit owners, and they anticipate operating six to seven deep-sea charter boats as well as five smaller skiff-type charter boats, and perhaps as many as two dive charter boats with additional demands for charters to be serviced by charter boats in the surrounding areas. Boating adverse impacts on the marine benthic communities inside and outside of the marina will be minimized by the construction configuration of the marina and boat slips, the shoaling and widening of the marina basin and canal, and the channel marking and tidal gauging provisions proposed by the Applicant/Respondents. These safety arrangements would be further enhanced by the above-mentioned restriction on the placing of boats into the waters of the marina and canal from the inland lakes. The configuration of the proposed modified marina and the shoaling will have a beneficial effect in rendering use by extremely large boats, which might cause propeller, wake or grounding damage to the marine benthic communities unlikely because of the inaccessibility caused by the intentional shoaling. Coral Reef Impacts Dr. Peter Glynn is a qualified expert in marine ecology and was accepted as an expert witness in that area with particular emphasis, through his long specialization, in the ecology of corals and coral reefs. He has researched the effects of sediments, herbicides, pesticides, oxygen levels, temperature, salinity, tidal effects and oil pollution on corals. He testified as a rebuttal witness addressing concerns raised by Petitioners' and Intervenor's witnesses with regard to boat traffic, attendant turbidity and possible synergistic effects on coral reefs caused by oils, greases, low oxygen levels and turbidity. Dr. Glynn has studied corals in many areas of the world including the Caribbean and the Florida Keys. The coral reefs in Florida are similar to those in the Caribbean area and belong to the same "biogeographic province." He has dived in and examined the Garden Cove area and found four species of small reef building corals in Garden Cove. These were found in the vicinity of a shipwreck near the channel entrance to Garden Cove and the remainder of the corals observed in Garden Cove were in the bottom of the boat channel running through Garden Cove. There were no corals observed on the grass flats and in shallower areas of Garden Cove. The corals occurring in the boat channel are in isolated colonies of less than a foot in diameter. The Petitioners and Intervenors attempted to raise the possibility of synergistic adverse effects on corals posed by combinations of oils, oxygen levels, temperatures and sedimentation or similar impacts. It was not shown how or at what concentration turbidity might combine with various oxygen levels, temperatures or degrees of light penetration to produce such effects, however. The only type of synergistic effects on corals Drs. Glynn and Corcoran have observed is that between oils and pesticides. Although this effect has been demonstrated in another study area far removed from the Florida Keys, no such pesticide and oil synergistic impact has been observed in the Florida Keys area, chiefly because it is not an agricultural area characterized by significant use of pesticides. Likewise it was not established that suspended sediments in the Garden Cove area could have an adverse effect on corals by reducing light penetration. In tropical areas such as the Keys, light penetration is often saturating or in greater quantities than are really needed for healthy coral growth and indeed, many corals in these areas have pigments that naturally shield them from excess light because these coral species actually can suffer from too much light penetration. Additionally, Dr. Glynn has observed good coral reef health and growth in areas that are highly turbid. It was not established that an increase of sedimentation deposit on corals will necessarily have an adverse impact, particularly because most corals can accept a substantial amount of fine-grain sediment deposition without adverse effect. The manner in which the proposed marina modifications will be accomplished will minimize sedimentation at any rate since the canal will be dammed off from Garden Cove until all work is completed and all sedimentation within the marina and marina access canal has subsided to levels compatible with the state standards for turbidity. In any event, there is no evidence that boat traffic in Garden Cove at the present time influences the distribution and health of live coral, particularly since the main coral abundance in Garden Cove occurs in the heavily-used boat channel at the present time. Likewise, Dr. Glynn established that sediments from any increase in boat traffic in Garden Cove will not likely drift out on the offshore reef tract and be deposited on the reefs to their detriment in any event, since the fine sediments occurring in Hawk Channel and in Garden Cove, are largely precluded from deposition on the offshore reefs because the waters over the reef tract offshore have very different physical characteristics. That is, there is distinct interface between the inshore and oceanic waters caused by the strong wave assault and current action near the reefs, which precludes the fine sediments from the inshore areas remaining in the area of the reefs. Finally, any increase in the number of people visiting the Pennekamp Park attributable to use of the modified marina will not inevitably lead to degradation of the reefs. By way of comparison, studies of Kaneoi Bay in Hawaii where a major pollutant source from human sewage caused degradation of the coral reefs, showed that when sewage effluent was subsequently directed away from the reefs, the reefs rejuvenated and repopulated and are now used extensively for recreational activities without observable biological degradation. These studies are consistent with studies Dr. Glynn referenced with regard to Biscayne Bay National Park, which have shown no significant degradation occasioned by human visitation of the reefs in that park. Those studies have not shown a significant difference between the health of the "controlled reefs" and the reefs which are allowed to be used for recreational purposes. It was thus not established that there will be any degradation of the corals in the near-shore areas of Garden Cove nor in the offshore reef areas occasioned by any increased boat traffic resulting from the modification of the marina. Indeed, it was not demonstrated that the mere modification of the marina, which will actually accommodate fewer boats than are presently permitted, will cause any increase in present boat traffic at all. Dr. Glynn, in the course of his teaching and studies in the field of marine ecology has become familiar with the causes and effects of Ciguatera toxin in marine environments. He recently participated in the study of possible Ciguatera toxin at the grounding site of the freighter Wildwood on Molasses Reef, some miles distant from the marina site. All cases reported of such harmful concentrations of this toxin have originated from open water, outer coral reef environments, and not from near shore areas such as those involved in this case, where seagrasses and mangroves are the dominant marine communities. Ciguatera toxin organisms require clear open ocean water with strong currents and well-developed coral reefs which are found offshore in the Keys and not in the near-shore mangrove-type environments. The cause of Ciguatera is a concentration of toxin in the food chain. Although the bacteria that cause Ciguatera Toxin in fish, and resulting harmful effects in humans, occur everywhere in marine waters, the bacteria are not a hazard because generally, conditions are not appropriate for the bacteria to multiply. The two main species of dinoflagellates, that have been associated with causing Ciguatera poisoning do not occur in an environment such as the Port Bougainville Marina. They are typically concentrated in larger fish such as snapper, grouper and barracudas which cause problems when they are eaten by people. These species are not generally found in the inshore mangrove and grassbed areas such as are involved in the case at bar. Thus, the concerns expressed by Petitioner's witnesses concerning the possibility of Ciguatera poisoning occurring because of possible damage to corals and coral death caused by the dredge and fill operations, and boat operation associated with the marina and Garden Cove are, in reality, only unsubstantiated speculation.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, RECOMMENDED: That the State of Florida, Department of Environmental Regulation, issue the requested permit subject to the conditions incorporated in the agreement or "conservation easement" executed between the Department and the Respondents with the further condition added to that conservation easement such that the deposition of boats from the inland lakes system into the marina and its access canal be prohibited.

Findings Of Fact Mr. C. A. Rossetter, Petitioner, owns and resides in a house located adjacent to the Indian River at 1020 South Patrick (now Riverside) Drive in Indialantic, Florida, and has resided on that property for approximately 21 years. He owns a 31-foot power boat which draws 3.5 feet of water and is currently docked at his sister's house in neighboring Eau Gallie, Florida. His own property has no dock at the present time, and the water depth in the river, which out to a distance of several hundred feet is less than 3.5 feet, is therefore too shallow to allow access to his property by his boat. On June 11, 1982, Petitioner submitted a request to the Department to dredge, subsequently assigned number 050567924, which was received in the local office of the Department on June 15, 1982. This request was for permission to dredge next to a boat pier to be constructed which would allow access with his boat. The area to be dredged was 15 feet wide from the shoreline, out 100 feet to the end of the pier, then an additional 100 feet beyond, with a 15- by 20- foot area in front of the "L" end of the pier, north of the main dredging area. Drawings submitted with the application indicated the total volume to be dredged was 300 cubic yards. Proposed use of the property was to be private. When the application was received by the Department, it was reviewed by Barbara Bess, a marine biologist, in August, 1982. In September, 1982, Ms. Bess visited the site, talked with the Petitioner, and made general observations as to the site, the river, and the surrounding property. She returned to the property on October 7, 1982, with her supervisor, Mr. Reese Kessler, from the Department's Orlando office. Mr. Kessler is an expert in the effects of dredging on marine species and habitat. As a result of the two visits and her evaluation, on October 8, 1982, Ms. Bess submitted a memorandum on this application in which she thoroughly described the request, the area, and the effect the dredging would have on the ecology, ultimately concluding that the public interest would not be served by permitting the dredging of a navigational channel for one private landowner 1/ and that it would be far less damaging to the already impacted area to construct a long dock which, if kept under 1,000 square feet in area, would qualify for exemption from permit requirement status. She also recommended that the permit be denied. Thereafter, on November 9, 1982, the Department issued the Intent to Deny, pointing out that the proposed dredging would adversely affect 3,300 square feet of the Indian River marine biological resources, would serve only one individual property owner, and, therefore, was not in the public interest. The area where the Petitioner proposed the operation is exclusively residential with commercial areas approximately one mile to the south and three miles to the north at the causeways. Petitioner's property extends approximately 120 feet on the river and eastward to South Patrick Drive. The residence is a single family dwelling. Petitioner had previously installed a seawall approximately five feet waterward of mean high water. The area between the seawall and the shoreline has weed-covered water and has not been filled in. Petitioner had a prior permit for a dock (since expired) which called for a sloping riprap in front of the seawall. This has not been done. The river bottom at Petitioner's property is an almost totally unvegetated soft, fine gray sand and silt. There is an abundance of marine life present, however, including penaid shrimp, polychaetes, Nemertean worms, comb jellies, mollusks, annelids, and fish, primarily mullet. Dredging would be by means of a suction dredge to cut into the bottom. With the exception of one species of edible clam, the majority of the invertebrate sea life in the area serves as the bottom part of the food chain in the area as food for more advanced sea life forms such as fish, crabs, etc. Mullet, for example, which is quite populous here, is a commercially valuable species, as are snook, trout, and snapper. Dredging of the channel proposed would remove the top 2.5 feet of bottom, along with all the marine life that it contains. In its place over a period of time would accumulate a black, oozy silt (known to some as black mayonnaise) which settles into any depression left in the bottom. This silt permits the growth on nonlight-requiring algae and other plant life which, when decaying, creates hydrogen sulfide, the substance responsible for the terrible odor often experienced in the area. In addition, other types of less desirable life forms come in to replace that which is taken. While experience has shown in other areas where dredging has taken place that there is some regeneration of beneficial and favorable life forms, the affected area will never have the same degree of population of desirable sea life as exists before dredging. This is caused by the accumulation of silt in the dredged area which blocks oxygen from getting to the organisms which live in the bottom. Almost any activity can have an adverse effect on the bottom, such as walking across the bottom, water skiing above it, etc., but these activities, which do not deeply scar the bottom, have only a short-term and unmeasurable impact. A comparison of this short-term damage to the long-term damage of dredging and removal of a part of the bottom clearly reveals that the by far greater adverse impact comes from dredging. That which is removed by dredging is not soon replaced. Admittedly, the holes needed to insert pilings for the dock would also cause some damage, but not nearly as much. What is significant is the degree of damage caused by the options. In determining whether or not to grant a permit, the agency considers several factors. One is whether there will be damage to the ecology and the environment, and if so, how much. A second factor is the cumulative effect-- would this permit establish a precedent that would be undesirable from an ecological viewpoint? In the event there are affirmative findings of potential damage and the degree thereof, the next question is whether to grant the permit would be in the public interest. Here, in the opinion of Ms. Bess and Mr. Kessler, it would not. Other dredging in the area, such as that accomplished by the county approximately a mile from this site, which benefited only six families, cannot be compared because it was only to clean out a channel which had previously been dredged. Petitioner's would be cutting into virgin bottom and to do so for one family's private use, with its precedent-setting potential, when a far less damaging alternative is available cannot reasonably be justified as in the public good. Dredging for Petitioner in this area would have a substantial adverse impact on the marine ecology of the immediate area. Petitioner, as a riparian owner, has the right to enjoy his property, but the proposed alternative of a dock gives Mr. Rossetter ingress and egress to his property from the water with the least harm to the ecology of the river. Petitioner was served with a series of interrogatories pursuant to Rule 28-5.208, Florida Administrative Code, on January 10, 1983. He failed to answer these interrogatories. Petitioner was also served with a Request for Admissions under the same rule on January 20, 1983, and again failed to respond. Petitioner at no time requested relief from either attempt at discovery, even though he was reminded of his failure to comply, by the Hearing Officer, at the hearing.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That Petitioner's request for a dredge permit be denied. RECOMMENDED this 6th day of April, 1983, in Tallahassee, Florida. ARNOLD H.
