The Issue The issue is whether, pursuant to Section 161.053, Florida Statutes, and Rule 62B-33.005, Florida Administrative Code, Petitioners are entitled to a coastal construction control line permit to build a single-family residence in Volusia County with a structural elevation of 19 feet National Geodetic Vertical Datum, not 24 feet National Geodetic Vertical Datum, as required by Respondent.
Findings Of Fact Petitioners own an undeveloped lot located at 4279 South Atlantic Avenue in the Wilbur-by-the-Sea subdivision in unincorporated Volusia County. Mr. Humphries' family has owned the lot for 50 years. The rectangular lot is 210 feet deep and 50 feet wide. The narrower end abuts the Atlantic Ocean on the east and South Atlantic Avenue on the west. The south boundary of Petitioners' lot abuts a developed lot. The house located on this lot has a finished- floor elevation of 26.15 feet National Geodetic Vertical Datum (NGVD). This is consistent with the structural elevations of most of the residences in the immediate vicinity of Petitioners' lot. Even though the seaward extent of Petitioner's proposed structure is roughly in a line with the seaward extent of the nearby homes, the issue in this case is the structural elevation. The north boundary of Petitioners' lot abuts the 50- foot-wide right-of-way of Major Street. In 1984, a wooden walkway was constructed in the southern half of the Major Street right-of-way to allow pedestrians access to the beach. By that time, Major Street was no longer open for vehicular access. However, the construction and maintenance of Major Street may have contributed to the lower elevations on the north boundary of Petitioners' lot, as described below. Nearly all of the lots in the vicinity of Petitioners' lot have been developed; most, if not all, of them contain single-family residences. Petitioners, who are nearing retirement, wish to construct a house that would accommodate them in their later years when they expect their mobility to be reduced. Petitioners' house will sit atop a prominent secondary dune, as do all of the other oceanfront homes in the immediate vicinity. The house will also be confined roughly to the landward half of the lot. These factors mean that the relatively short driveway leading from South Atlantic Avenue to the garage will be relatively steep. Petitioners proposed a reduction in the top of the dune to reduce the steepness of the driveway and the difference in finished-floor elevations between the garage and the house. Generally, the south side of Petitioners' lot is higher than the north side. The seasonal high water line is 8.4 feet NGVD. The lot's east boundary, which is 7-8 feet landward of the seasonal high water line, is about 11.5 feet NGVD. The elevation of the south boundary rises to 28.5 feet NGVD, at a distance slightly east of the most seaward extent of the 10-foot wooden deck that is the most seaward structure proposed by Petitioners. The elevation of the north boundary does not rise much; over the same distance, it reaches only 12 feet NGVD. Proceeding westward, toward South Atlantic Avenue, the south boundary drops from its 28.5-foot elevation. Parallel to the proposed house, the boundary remains at about 25 feet NGVD, except it drops to about 20 feet at the point where the house would meet the garage. For the length of the 26-foot garage, the south boundary drops to 18.5 feet NGVD. For the length of the 30-foot section of driveway between the garage and the west boundary, the south boundary drops from 18 feet NGVD to 17 feet NGVD. The north boundary rises to its highest point, 20.6 feet NGVD, at a point just landward of the point along the boundary closest to the junction between the proposed wood deck and the house. Running parallel to the proposed house, the north boundary drops to about 18 feet NGVD (directly across from a point along the south boundary that reaches about 25 feet NGVD) and then to about 17.5 feet NGVD, at a point just landward of the point closest to the junction of the proposed house and garage. The proposed house would occupy elevations, prior to proposed site preparation, of about 28 feet NGVD at the seaward side, 22-26 feet NGVD at the midpoint, and no more than 21 feet NGVD at the landward side. The proposed deck, house, and all but a sliver of the garage lie seaward of the coastal construction control line. The northeast corner of the proposed house is 72 feet seaward of the coastal construction control line. The dune is largely vegetated. The vegetation includes sea oats, shrubs, and some palm trees, although Brazilian pepper, a nuisance exotic, also vegetates part of the dune. Just seaward of the southeast corner of the proposed deck is a hole, perhaps from past excavation, about ten feet deep and occupying 8-10 percent of the lot. This is the only portion of the lot significantly below-grade. Overall, the dune is functional and healthy. To the extent that it has been disturbed in the past, the dune seems to be recovering vigorously. On or about July 21, 1999, Petitioners applied for a permit to construct a residence seaward of the coastal construction control line. In their application, Petitioners proposed a structural elevation of 19 feet NGVD. The structural elevation, which is about two feet lower than the finished-floor elevation, is the lowest portion of the effectively horizontal structural elements supporting the floors and walls of the structure. Respondent's examination of the application raised concerns about the proposed structural elevation of 19 feet NGVD. The greater elevation of much of the dune under the footprint of the house would necessitate the relocation of dune materials on the lot or removal of dune materials off the lot. However, discussions between Respondent's representative and Mr. Bullard, Petitioners' engineer, failed to identify design modifications upon which both sides could agree. Thus, on June 5, 2000, Respondent issued a Final Order and Notice to Proceed Withheld (Final Order). The Final Order states that Respondent found that Petitioners' application was complete on March 6, 2000. Although the Final Order generally contemplates that construction will eventually proceed, Special Permit Condition 1 prohibits construction until Respondent issued a written notice to proceed. Special Permit Condition 2 warns that Respondent will not issue a notice to proceed until Petitioners submit plans that raise the structural elevation to 24 feet NGVD, relocate all excavated materials seaward of the coastal construction control line (but not more than 120 feet seaward of the line), prohibit net excavation seaward of the coastal construction control line, and specify the planting of all filled or disturbed areas with salt-resistant native vegetation transplanted from onsite areas that will be excavated and other sources, as needed. Special Permit Condition 7 requires Petitioners to obtain the fill material from a source landward of the coastal construction control line. The fill material also must be of a sand that is similar to that onsite in terms of grain size and coloration. However, nothing in the Final Order specifies any requirement to replicate present--or design scientifically verified new--seaward and landward slopes of the portion of the impacted dune. In resisting Respondent's demand to raise the structural elevation, Petitioners have sought to reduce the slope of their driveway, which involves traffic-safety issues in turning on and off busy South Atlantic Avenue, and eliminate the need for an extensive design modification to allow wheelchair- bound persons access to the house from the garage. At the hearing, Petitioners offered mitigation in the form of an artificial dune to be constructed seaward of the residence with excavated materials. However, this proposal would destroy existing vegetation and failed to specify slopes, so that the artificial dune would likely suffer significant and rapid erosion. Petitioners have failed to prove that their proposed construction activities, with a structural elevation of 19 feet NGVD, would not adversely impact the most prominent dune landward of the ocean, so as to reduce the existing ability of this dune to resist erosion and protect upland persons and property.
Recommendation It is RECOMMENDED that the Department of Environmental Protection enter a final order dismissing Petitioners' challenge and issuing the Final Order and Notice to Proceed Withheld dated June 5, 2000.

Findings Of Fact Charlotte County lies on the eastern shore of the Gulf of Mexico. The mainland is protected by a series of low lying barrier islands running more or less north and south. Manasota Key, Don Pedro Island and Gasparilla Island are the consolidated remnant of seven or more smaller islands. In all, Charlotte County has about 14 miles of sandy beach on the Gulf. The location of the shoreline is not static. Along the stretch of beach between Stump Pass and the Sarasota County line, for example, the shoreline moved gulfward between 1883 and 1975, while the shoreline south of the pass moved landward between 1883 and 1939, then gulfward between 1939 and 1975. In very broad geological terms, the tendency of barrier islands is to migrate toward the mainland, but accretion is also ongoing. In general, the Charlotte County islands have moved further into the Gulf during the last century. Annual variation is typical: accretion in summer and fall follows erosion in winter and early spring. Respondent DNR has placed reference monuments along the Charlotte County beaches every 1,000 feet or so, 68 in all. In May of 1974, DNR surveyed a profile of the beach at each station and also made a record of the bottom profile. Offshore profiles were done at every third range to a depth of 30 feet, and, at the other ranges, out to a wading depth (four feet below mean sea level). Using this information, DNR promulgated Rule 16B-26.06, Florida Administrative Code, which established the existing coastal construction control line (the 1977 line). STANDING By law, DNR's Division of Beaches and Shores has permitting authority over certain activities, notably building construction, in the area between the mean high water line and the coastal construction control line. The proposed rule amendment under challenge here would establish a new coastal construction control line (the proposed line) for Charlotte County that would lie landward of the 1977 line along most, but not all, of its length. Except for Lisa Noden, the petitioners and intervenors in these consolidated cases own property in Charlotte County on the Gulf of Mexico, including property lying between the 1977 line and the proposed line. Intervenor Boca Grande Club, Inc. owns Gulf frontage on Gasparilla Island including land lying between the 1977 line and the proposed line. On November 30, 1984, Boca Grande Club, Inc. had "the present intention to apply within the next six months for the necessary construction permits for a structure to be located on its real property," Intervenors' Exhibit No. 9, landward of the 1977 line and seaward of the proposed line. Respondent stipulated to the intervenors' standing. Dean L. Beckstead, president of Charlotte Harbor Land Company, has overseen the construction of 70 to 75 houses on that parcel of Don Pedro Island extending from Stump Pass 8000 feet south and from the Gulf of Mexico to Lemon Bay. With respect to some of these houses, construction is ongoing. The plan is to build additional housing, but no more than 50 residential units in all. In keeping with past practice, new construction would be well landward of the 1977 line, because of Mr. Beckstead's great respect for the ocean, but might be seaward of the proposed line. William McCrabb of Sarasota is an officer of a corporation, Nabob of Florida, Inc., that owns Gulf-front property on Manasota Key. He is also a general partner in a partnership that owns adjacent Gulf frontage. A 17-unit condominium has been completed on one parcel and plans exist for a 125-room hotel on the other. The only element of the hotel project seaward of the 1977 line is a planned dune overwalk. A larger portion of the hotel project would be seaward of the proposed line. Petitioner Charles Guy Batsel owns a house that sits on Gulf-front property in Charlotte County. Some 5,000 square feet of this parcel lie between the 1977 line and the proposed line. Even when obtaining a coastal construction permit does not result in changes in a project that have an adverse economic effect on a landowner, the costs associated with the permitting process itself may be substantial. The testimony of Randall Craig Norden, a developer, that he spent approximately $100,000, or at least 2.5 percent of the total cost of Phase Three of Colony Don Pedro, on attorney's fees, engineering fees, travel to Tallahassee and other expenses associated with obtaining a coastal construction permit, went unrebutted. REVISITING THE 1977 LINE After it came to the attention of DNR staff that erosion along parts of the Gulf shoreline in Charlotte County had resulted in the 1977 line's approaching the water's edge in several places, staff recommended that the line be reexamined. The Governor and Cabinet, in approving DNR's annual work program in 1983 and in voting to enter into a contract with Florida State University for, e.g., "Studies to Reestablish Control Lines," Petitioners' Exhibit No. 3, on July 1, 1983, ordered a comprehensive review. Even before the Governor and Cabinet took these actions, DNR staff performed a survey in Charlotte County in 1982 to determine beach and bottom profiles at the same points at which they had been measured in 1974, although in two or three instances, the monuments had washed away. On Manasota Key between ranges 1 (the northernmost in Charlotte County) and 5, the mean sea level line receded an average of 15 feet between May of 1974 and December of 1982. The mean sea level moved further toward the Gulf on average between ranges 6 and 11, but receded an average of 20 feet between ranges 12 and 18. Between ranges 16 and 24, no relocation of the coastal construction control line has been proposed. Displacement of sand when Stump Pass was dredged may have affected the shoreline south of the pass, although shorelines in the vicinity of inlets are ordinarily unstable. On Don Pedro Island, just south of Stump Pass, there has been accretion. Between ranges 27 and 39, which lie still further south of Stump Pass, the mean sea level line receded an average of 81 feet between May of 1974 and December of 1982. Between ranges 45 and 49 the line has moved an average of 32 feet landward while there has been accretion, on average, between ranges 50 and 55. At range 60, the northern end of Gasparilla Island, the mean sea line had receded 100 feet between May of 1974 and December of 1982 and another 10 feet by September 14, 1983. At range 61, the mean sea level line had moved seaward by 100 feet between May of 1974 and December of 1982, while at range 62 there was a seaward shift of 75 feet over the same period. At range 63, there was accretion between May of 1974 and December of 1982 but erosion brought the mean sea level line landward of its May 1974 location by September of 1983. Between ranges 6 and 67, the average recession of the mean sea level line was 76 feet. By one calculation, the county as a whole lost about 59,000 cubic yards of beach material between May of 1974 and December of 1982. Measurements made shortly before the "No Name" tropical storm occurred, in the summer of 1982, suggest that the storm did not significantly affect these measurements of long term trends. At no time did riparian landowners or officials of Charlotte County or any affected municipality make any written request that the coastal construction control line be moved, although Franz H. Ross, one of Charlotte County's county commissioners, testified at the hearing that the 1977 line needed replacement. He did not endorse DNR's proposed line. After the 1977 line was drawn, the enabling legislation was twice amended. The first reference to a 100-year storm surge appeared in 1978. Ch.78-257, Section 5, Laws of Florida (1978). More recently, storm waves as well as storm surge became a statutory criterion. Ch. 83-247, Section 2, Laws of Florida (1983). Not only have new laws and a new beach emerged since the 1977 line was established, but there have also been advances in scientific analysis and prediction of the behavior of storm waves, notably with reference to surf beats or "dynamic wave set up." ECONOMIC IMPACT STATEMENT DNR prepared a 27-page economic impact statement in which it estimated the costs of the proposed line to the agency, and costs and benefits to persons directly affected by the proposed rule; and made a detailed statement of the data and method used in making these estimates. With respect to the impact of the proposed rule on competition and the open market for employment, the economic impact statement noted that construction costs would increase under the proposed rule, causing a "market adjustment period" during which "builders would have to absorb the cost increase themselves or delay construction while prices rise sufficiently . . . Postponing of construction would tend to reduce employment . . . temporar[il]y. . . . Petitioners' Exhibit No. 5, p. 13. Although portions of the economic impact statement were originally drafted for Dade and Broward County control lines, they have obvious application to Charlotte County, as well. The thrust of the cost-benefit analysis was that construction costs would increase in the area between the 1977 line and the proposed line, but that enhanced preservation of the beaches, and decreases in flood insurance premiums and storm damage potential would more than offset these increased costs. The increase in construction costs was attributed to the expense and delay of obtaining a coastal construction permit, the additional labor and materials necessary to elevate the structure above the predicted level of storm waves in a 100-year return storm, and the relatively insignificant cost of installing stronger connections (hurricane clips for the roof and bolted- metal straps over joists to secure them to supporting piles) so that the structure could withstand wind loads of 140 miles per hour. Petitioners did not disprove the reasonableness of the permitting cost assumptions in the economic impact statement, the evidence of Colony Don Pedro's experience notwithstanding. Fire escapes and access for handicapped persons were not taken into account, but the evidence did not show that differential costs for those items would affect the conclusions of the economic impact statement. The economic impact statement assumes that buildings would have to be elevated off grade even without the additional coastal construction control requirements, and that foundations would be designed by engineers, in any case. Neither assumption was proven false. The assumption that costs increase in direct proportion with elevation yields only a very rough estimate of differential costs. The differential cost analysis did not take fully into account the criterion that applies in coastal construction permitting that relates to a structure's two-dimensional "footprint." DNR permitting staff may recommend denial of a permit even though a proposed building meets all structural integrity requirements whenever, on a site-specific basis, the area to be covered by the building fails to "minimize any expected adverse impact on the beach system." Rule 16B-33.07(2), Florida Administrative Code. In such circumstances, one resolution may be to place the proposed structure at a more landward site, and the economic impact statement does address the economic consequences of removing structures landward, but other resolutions, such as scaling down the project or decreasing floor size and adding floor(s) are not considered. In this connection, there is no mention of Charlotte County's three-story (35 feet) height limitation nor, in general, does the economic impact statement identify what Charlotte County ordinances now require for coastal construction. On the benefit side, some of the flood insurance rate comparisons are inappropriate because Charlotte County will not allow floor elevations several feet below base flood elevations set by the Federal Emergency Management Agency, as the economic impact statement assumed for comparative purposes. The rate differentials also apparently ignore the fact that the same structure at a higher elevation will be worth more and have a greater insurable value. From Petitioners' Exhibit No. 23, moreover, it appears that federally subsidized flood insurance may no longer be available in certain parts of Charlotte County. But the Sheaffer and Roland study, Respondent's Exhibit No. 14, to which the economic impact statement refers, shows that elevating a structure to the wave crest level instead of to the storm surge level of a 100-year return storm creates additional benefits in the form of lessened storm damage potential (without regard to insurance premiums) that exceed the additional costs. With respect to benefits as well as costs, the economic impact statement suffers from a failure to explicate existing requirements of local law governing building construction. Without this base line, differential costs and benefits were not and cannot be quantified precisely for the specific case of Charlotte County. But see page 12 of Petitioners' Exhibit No. 5. The evidence adduced at hearing failed, however, to discredit the general conclusion of the economic impact statement that requiring sufficient elevation and sufficiently sturdy connections to withstand a 100-year storm event, including the wave crests it would generate, was cost effective, assuming the structure is to have an engineered foundation off grade, in any event. Precise quantification of the economic impact of the site coverage criterion DNR will extend to the area between the 1977 line and the proposed line, if the latter takes effect, may be impossible. The benefits will accrue to the beach and to adjacent landowners as much as to the owner of the structure and both costs and benefits will vary from parcel to parcel with changing topography. THE SANDS OF TIME Under conditions that have recently obtained in Charlotte County, sloping sand beaches climb from the water's edge to the toe of a more or less pronounced primary sand dune, behind which other dunes undulate in succession across the barrier islands to Lemon Bay or Gasparilla Sound, from which they are occasionally insulated by mangrove swamp. Vegetation over much of the islands, which vary from 200 to 2000 feet in width, attests to their present stability. But chances are that a hurricane will in time strike, flattening the dunes, spreading the sand well inland everywhere, all the way across the islands in some places, and leaving a wide beach face without, in many places, any discernible dunes. Such a reconfiguration will ineluctably result from the major hurricane identified as the 100-year return storm. Thereafter, under more favorable weather conditions, dunes will grow and reemerge, comprised of sand the Gulf gives back as well as the sand strewn across the island by the storm, unless surface impediments prevent. The cycle complete, dunes will again stand their erosion-damping vigil against the sea, a buffer protecting the mainland, as well as insular upland. In establishing coastal construction control lines, DNR is charged by statute with the job of "defin[ing] that portion of the beach-dune system which is subject to severe fluctuations based on a 100-year storm surge, storm waves, or other predictable weather conditions." Section 161.053(1), Florida Statutes (1983). DNR naturally looks to the beach dune system in the configuration it is predicted to assume after a 100-year return storm in defining "that portion of the beach-dune system which is subject to severe fluctuations based on a 100- year storm . . ." The folly of limiting consideration to the landward toe of a primary dune as it existed in a period of fair weather was well illustrated by the photograph that came in evidence, as Respondent's Exhibit No. 12, of a monument placed behind a dune in St. Johns County only recently that is now well down on the beach. DNR METHODOLOGY In drawing the proposed line, DNR followed the procedure it employed in establishing coastal construction control lines in Nassau, Franklin and perhaps other counties. The line proposed for Martin County was drawn in the same fashion. By statistical inference from historical data, five characteristics of a predicted 100-year return storm are identified: central pressure deficit, radius to maximum winds, speed of hurricane system translation, hurricane direction (track angle), and landfall location or some other geographical reference. In order to assess the likelihood of various combinations of storm attributes actually observed, cumulative probability curves are generated and predictions of storms and their characteristics over several hypothetical 500- year time periods are made. Of each 500-year suite of storms, the fifth most severe is chosen as the 100-year return storm. A date between June 1 and November 30, 1982, is chosen at random and astronomical tides on that day are assumed to coincide with the 100-year return storm. Using the average characteristics of the 100-year return storm, associated wind velocities and storm surge are predicted. Astronomical tides, barometric pressure, wind stress, and the Coriolis effect all contribute to the height of the still water storm surge," the water level that you could measure at a point due to a hurricane's passage if you could turn off the waves." Dean's deposition at 31. The storm surge prediction model also takes storm waves into account: Maximum wave height is 78 percent of water depth. As storm waves approaching a beach reach the break point, their height falls by five percent, but the waves attain and exceed their former height by the time they reach shore. Waves have momentum which, as they break, is transferred, at least in part, "to the water column in the form of a wave setup." Dean's deposition at 32. For many years, "static wave setup" has been observed in wave tanks where waves of the same size have been set in motion to break against a wall of the tank. For six years or so, Drs. Dean and Chiu and others have been convinced that an additional allowance should be made for surf beats or "dynamic wave setup," to reflect the fact that waves in nature do not occur in uniform sizes at regular intervals. Their magnitude oscillates, in the case of breaking storm waves, around the still water surge elevations. To allow for dynamic wave setup, the static wave setup component of the predicted surge elevation is increased by half. The 100-year storm surge height is then used to predict, taking observed beach profiles into account, the landward penetration of waves which will have degenerated to a height of three feet and, with the aid of a mathematical model, the extent to which stormwater transporting sand offshore will cause erosion. At each range, unless a three foot wave is predicted to go further landward, the point to which erosion by offshore transport is predicted to occur is chosen as the endpoint for a segment of the coastal construction control line. Where penetration of a three foot wave farther landward is predicted, the coastal construction control line is drawn on that basis, in light of topography on either side of the range involved. In predicting the landward penetration of a three foot wave, aerial photographs or surveyor's field notes are consulted and, if there is vegetation along the range involved, a coefficient of friction is applied that simulates the existence of trees a foot in diameter with centers five feet apart. At the hearing, the use of a three foot wave horizontal penetration criterion was called into question, and there is an apparent difference of opinion between two of DNR's experts, Dean and Chiu, as to the significance a three foot wave has for the beach dune system. The three foot wave is notorious. This unassuming natural phenomenon has become laden with engineering and legal significance, ever since 1962 studies the Army Corps of Engineers performed in Galveston, Texas, showed that a three foot wave had enough energy to demolish a frame structure built on grade. If it has as much energy as that, Dr. Chiu reasons convincingly, it also has enough energy to transport significant amounts of sand and to damage vegetation. With its sand-holding properties, vegetation plays a critical role in the beach- dune system. Evidence that a three-foot wave does not rearrange substantial quantities of sand, if any was adduced, has not been credited. Even Dr. Dean reported seeing three foot waves moving substantial quantities of sediment. The mathematical erosion model, known for the inventor as the modified Kriebel model, assumes relatively higher sand dunes that are eaten away by waves transporting sand offshore. The erosion model does not take into account lateral movement of sand or the effects of waves overtopping a dune and carrying overwashed sand inland. The model predicts what distance inland an assumed storm surge will move various contours. By comparing the model's predictions to the effects of actual storms, calibration has been possible. After Hurricane Eloise hit Walton County, erosion along 25 miles of shoreline was observed and compared to the model's predictions. In order to draw a line landward of 98 percent of the points to which Eloise eroded the five foot contour, it was necessary to multiply the erosion model's prediction of the landward movement of the five foot contour by 2.5. With the 2.5 factor the model overpredicts for most of the coast affected by a storm, but underpredicts erosion for the point where the storm does its worst. The most severe erosion eats two and a half times further inland than average erosion along the affected coastline. AS APPLIED Underlying both approaches to drawing the proposed line was the prediction of the water height a 100-year return storm would produce. DNR calculated three storm surges, one for the northern, one for the central, and one for the southern Charlotte County coast, and predicted maximum water heights during a 100- year storm ranging from 13.1 to 12.7 feet above NGVD at the mean sea level line. Identifying the 100-year return storm for a particular locale is an elaborate exercise in probability theory that begins with the collection and analysis of historical data. At hearing, various criticisms of this process were advanced. Among them was the way certain data were assigned to categories or "bins." On rebuttal, the data were treated as discrete points and the result was the prediction of a storm surge .8 feet higher than the "bin" prediction method had yielded. Another criticism was the number of hurricanes selected as pertinent over the 80-year period studied. To the same effect was a criticism of the length of the period chosen. Reducing the number of storms from 28 to 20 causes the predicted storm surge to fall half a foot. Respondent's Exhibit No. In their proposed recommended order, intervenors contend Had DNR used . . . correct data in its development of the predicted 100- year storm surge level for Charlotte County, it would have simulated only 137 hurricanes for a 500-year period in Charlotte County. By simulating 182 hurricanes using the storm surge computer model, DNR simulated 45, or 33 percent, more hurricanes than justified. . . . P. 13 (footnotes omitted) The 33 percent is a red herring, since, as intervenors later note, the difference between simulating 182 hurricanes and simulating 125 hurricanes produces a difference of only .7 feet (from 12.9 to 12.2 feet) in the predicted storm surge, a difference of five or six percent. Nor was DNR's approach shown to be "incorrect." A certain amount of time at hearing was devoted to the categorization of hurricanes as alongshore (or bypassing), landfalling, or exiting. Different sources of data may be a source of confusion, if compiled with reference to different points of geographical reference. A hurricane that makes landfall in Miami may exit the peninsula in Charlotte County, while a hurricane that makes landfall in Tampa may bypass Charlotte County en route. Some confusion seems to have attended the integration of data taken from a National Weather Service publication that was used jointly with data from a NOAA source. Respondent's Exhibit No. 18 demonstrates that no significant distortion resulted, however. Among the historical storms omitted by DNR's consultants was the infamous Labor Day Hurricane of 1935, which generated storm tides of 18 feet at Marathon in the Florida Keys. Using only the 1973 NOAA data for Charlotte County yields predictions of storm surges a foot higher than DNR's consultants predicted. On Manasota Key, it was the erosion model that determined placement of the proposed line. Since the probability of the 100-year return storm hitting at any particular point on the Charlotte County coastline is virtually the same as for any other point on the Charlotte County coastline, the 2.5 factor is appropriate. The average amount of erosion over the whole of the affected coastline is of theoretical interest only. Between ranges 1 and 10 on Manasota Key, the dunes are 12 to 14 feet high, as compared to an average elevation for all three islands of slightly above five feet. The high dunes on Manasota Key, where the erosion model was used to set the proposed line, resemble the walls of a wave tank more closely than the lower dunes on Don Pedro and Gasparilla Islands, where stormwater is predicted to cross the islands and keep going. Dr. Chiu also predicted overtopping of Manasota Key. Dr. Dean's testimony was to the effect net overtopping might mean a diminution in wave height attributable to diminished dynamic wave setup of .3 to .4 feet. To this should logically be added a corresponding diminution attributable to diminished static wave set up, viz., .6 to .3 feet, for a total of up to 1.2 feet. The controversial testimony was that the storm surge model ignores altogether a documented phenomenon known variously as "initial rise," "forerunner," and "presurge anomaly," that adds 1 to 3 feet to surge elevations, and that this factor would offset any diminished wave setup almost entirely. Dr. Chiu's opinion that a three foot wave would cause overwash and damage to vegetation on Don Pedro and Gasparilla Islands, severely damaging the beach dune system, has been accepted. The contention that these phenomena are immaterial since they ware characterized as "severe impact on" instead of "severe fluctuations of" the beach dune system must be dismissed as a semantic quibble. Penetration of the three foot wave was the controlling criterion from Range 25 south to the Lee County line, although the average prediction of wave height at points where ranges intersect the proposed line is between 3.3 and 3.4 feet. These wave height predictions ignore, moreover, the erosion of the profile which is bound to occur. Witnesses on all sides agreed that a 100-year return storm would submerge Don Pedro and Gasparilla Islands. Waves three feet high and higher would travel across the barrier islands and Lemon Bay onto the mainland. In Charlotte County, use of the coefficient of friction was very conservative, inasmuch as vegetation on none of the coastal barrier islands approaches the density of trees one foot in diameter, five feet apart on centers. Trees a foot in diameter 15 or 20 feet apart cause only a four percent reduction in wave height every 100 feet as compared to the 20 percent reduction every 100 feet assumed for vegetated ranges in Charlotte County. PROOF IN PUDDING The conservatism of DNR's methodology is shown by damage done landward of the coastal construction control line in Franklin County, where a road upland from the line washed out during a storm of less than 100-year return magnitude and in Martin County, where as the result of a 10-year return storm severe topographical fluctuations were seen landward of the coastal construction control line proposed there. The storm surge model has been calibrated against storms of record, which has demonstrated its reliability, whatever the merits of its theoretical underpinnings. Even assuming some problems with the categorization of storm parameters put into the model for Charlotte County, the evidence adduced in this case does not support the conclusion that stormwaters in Charlotte County will reach an elevation of less than 11 to 12 feet, in the event of a 100-year return storm. The evidence overwhelmingly establishes that waves would reach at least that height. Respondent's Exhibit No. 2 shows what a storm surge of 11 to 12 feet did to a beach not dissimilar too Charlotte County's when Hurricane Frederic hit Gulf Shores, Alabama. Radical changes in topography occurred well landward of the point at which the proposed line for Charlotte County has been placed. This exhibit also shows why Mr. Tackney's opinion to the effect that a modest reduction in storm surge would permit sand dunes of a certain height to block the water's progress landward must be rejected. When a hurricane hits, the dunes are so dramatically eroded that their former height is not determinative. Although DNR ignored this factor in calculating the horizontal penetration of a three foot wave, in order to make the proposed line conservative, erosion of the profiles is inevitable. The Kriebel erosion model is designed to show what amount of sand stormwater will move offshore when a dune takes the full force of stormwater. When dunes are not high enough to do that, some other criterion for a coastal construction control line is necessary to reflect the different types of erosion that hurricane Frederic and other storms have shown will occur. Overwashed sand deposits stretched 800 feet and more from the water's edge after Frederic abated. The parties proposed findings of fact have been considered and have been adopted, in substance, except where unsupported by the weight of the evidence, immaterial, cumulative, or subordinate.
Findings Of Fact Petitioner, Wingfield Development Company (WDC), is a real estate development company located at 390 North Orange Avenue, Suite 1800, Orlando, Florida. In late 1982 or early 1983, WDC began developing a resort project known as Turtleback Beach Club (the project) in Indian River County. When completed, the project will consist of a 256 unit hotel, 68 villas, two swimming pools, a number of cabanas, a reverse-osmosis water plant, and other amenities which will cost approximately $50 million. All structures were designed to be constructed landward of the then existing coastal construction control line (CCCL). The date of establishment of the original CCCL is not of record. From late 1982 or early 1983 until 1987, WDC expended approximately $1.4 million on the project. Among the expenditures were the preparation of extensive cite and design plans, the installation of off-site utilities, and the fabrication and installation of some two hundred pilings and a number of pile caps. All such work was performed landward of the then existing CCCL. On March 5, 1987 respondent, Department of Natural Resources (DNR), reestablished the CCCL in Indian, River County. The new CCCL was more landward than the original CCCL. This resulted in several portions of the project, including all or parts of the villa and hotel, being seaward of the new CCCL. In November 1987 WDC was advised by the Indian River County Building Department to cease construction activities because, after consultation with DNR, it has decided not to make any further inspections. On April 4, 1988 DNR advised WDC by letter that, after making a site review of the project, it had determined that: the foundations for the hotel structure and the cabana located in the southeast portion of the property were `under construction' pursuant to the definition contained in Subsection 16B-33.002(56), Florida Administrative Code, at the time of the reestablishment of the coastal construction control line on March 4, 1987, ... (and that) the remaining five proposed cabana structures located on the south half of the property and shown to be seaward of the new control line, the proposed swimming pools, decks and gazebos, parking areas also shown to be seaward of the new control line and any other proposed landscaping work were not `under construction' pursuant to the definition. The letter added that the: staff shall consider the exemption status for the hotel and the one cabana under construction void if construction activity on these structures remains idle for a period of six months from the date of receipt of this exemption determination and prior to completion of the structures. Finally, the letter required petitioner to submit: a proposed `build out' schedule (that) would entail providing (the) staff with specifics of where (petitioner) expect(s) the overall project to be at ninety (90) day intervals up through completion of the structures located seaward of the coastal construction line. The staff feels that two years should be more than ample time with which to complete that portion of the project located seaward of the coastal construction control line. Progress must be maintained on each structure during each six month interval. Additionally, should your project fall short of any ninety day progress levels to be referenced in your `build out' plan, your project will lose it's (sic) exemption status and all remaining portions of the project, seaward of the control line will require a permit from the (DNR) in accordance with the provisions of Section 161.053, Florida Statutes. Because the letter offered a point of entry to contest the proposed agency action, WDC requested a section 120.57(1) hearing. At the same time, it continued construction on the project. On November 25, 1988 DNR issued further proposed agency action in the form of a letter advising WDC that, based upon a review of WDC's exemption file, the exempt status of the project had been "lost" and that any further construction activity seaward of the CCCL would require a permit from DNR under section 161.053. The receipt of this advice prompted WDC to file a second request for a section 120.57(1) hearing and a petition seeking to invalidate what it perceived to be an illicit rule, or in the alternative, the two rules from which the statements were drawn. WDC contends that DNR's requirement that, once a project is given an exempt status, it must remain under active construction and the owner must submit for DNR's approval a "build out" schedule, is an illicit rule since such a requirement is not contained in DNR's rules. Under state law, as implemented by DNR, no construction activity may take place seaward of a CCCL without a permit from DNR. However, any projects that are under construction at the time of the establishment of the CCCL are exempt from such permitting requirements. Under the current DNR organizational structure, the Division of Beaches and Shores (Division) is charged with the responsibility of administering and enforcing the CCCL regulatory program. The Division's Bureau of Coastal Engineering and Regulation has been assigned the task of performing a site review of all projects for which local building permits have been issued at the time of the establishment of a CCCL. If a project is under construction, as defined in DNR rules, at the time of the establishment of the CCCL, the owner may continue his activities even if the structures are seaward of the CCCL. A determination as to whether a structure is under construction at the time a CCCL is reset does not take into consideration the impacts the structure will have on the beach and dune system. This is because DNR considers such a determination to be regulatory in nature, and such impacts would be irrevelant to that decision. The Division construes its authority as also permitting it to require an exempt project to remain under active construction once it receives an exempt status. It does so on the notion that this insures that the exemption status was obtained in good faith, and the builder intended to go forward with the construction in a timely manner and as originally conceived. It has been DNR's experience that some property owners have engaged in a minimal construction program to circumvent the regulatory process. To prevent this, DNR has imposed a requirement that, if construction activity ceases for a period of six months or more, the exempt status will be lost. A six month time period was used because DNR realized that short, unforeseeable delays of less than six months were not uncommon. This policy has been uniformly applied, without discretion to agency personnel to do otherwise, on all projects classified as exempt. In addition, DNR has required project owners to submit to DNR staff a so-called "build out" schedule containing a construction schedule at ninety day time intervals with a time certain for completion of the project. This requirement, although infrequently used, has been uniformly imposed, when needed, upon all exempt projects, including that of WDC. The agency concedes that there is no specific statutory language authorizing the above requirements. However, it takes the position that these requirements are authorized and sanctioned by chapter 161 as a whole and by rules 16B-33.002(56) and 16B-004(1), which happen to be the rules challenged by WDC. Those rules read as follows: 16B-33.002 Definitions. (56) "Under construction" is the continuous physical activity of placing the foundation or continuation of construction above the foundation of any structure seaward of the established coastal construction or setback line. Under construction does not include application for or obtaining a building permit, a site plan approval or zoning approval from the appropriate local government agency having jurisdiction over the activity, purchasing construction materials, placing such construction materials on the site, clearing or grading the site in anticipation of construction, site surveying, continuation of site work beyond the limits of the foundation including landscape work or construction of nonhabitable major structures or rigid coastal or shore protection structures, or reactivating construction after substantially all construction activity has remained stopped for a period of six months or more. 16B-33.004 Exemptions from Permit Requirements. (1) Any structures under construction prior to the establishment of a coastal construction control line in a particular county are exempt from the provisions of Section 160.053, Florida Statutes, and this Chapter, except as noted in Subsection 161.053(12), Florida Statutes. Respondent acknowledges that there is nothing in rule 16B-33.004(1) that specifically authorizes it to impose the challenged requirements. However, it relies upon that part of the rule which reads "except as noted in Subsection 161.053(12), Florida Statutes" as implicitly authorizing this action. That statute removes the exempt status of a project if there are any subsequent modifications which "require, involve, ,or include any additions to, or repair or modification of the existing foundation of that structure." According to the Division director, it construes that language as authorizing it to make a determination as to whether the project owner has made any substantial changes in the nature of the project or if construction has been continuous. Respondent also relies upon rule 16B-33.002(56) which defines the term "under construction" as being "the continuous physical activity of placing the foundation or contination of construction above the foundation of any structure seaward of the established coastal construction control or setback line." The Division interprets this language to mean that construction must be continuous and without a cessation of activities of more than six months. This rule language is bottomed on subsection 161.053(9) which reads in pertinent part that "the provisions of this section do not apply to ... structures existing or under construction prior to the establishment of a coastal construction control line as provided herein; provided such structures may not be materially altered except as provided in subsection (5)." Finally, the agency relies upon subsection 161.053(1)(a) which sets forth the legislative intent behind the establishment of CCCLs. Among other things, the purpose of a CCCL is to protect, the beaches and dunes from imprudent construction which can "provide inadequate protection to upland structures." In the words ,of the Division director, DNR interprets this language to mean that it has the authority to "go back and look at projects once they are declared exempt, and to make sure that they remain exempt under the statute." The DNR documents which grant exemptions do not contain any reference to requirements that there be continuous construction on the project and that a build out schedule be submitted thereafter. Even so, DNR contends it is merely granting a "conditional" exemption conditioned on the project owner maintaining active and continuous construction. It posits further that, without such authority, its regulatory program would be rendered ineffective. However, the Division director conceded that, even without the imposition of these requirements, DNR still has authority to regulate all structures which are constructed seaward of the CCCL and to prohibit any material changes to an existing or partially completed structure. Petitioner intends to complete its project, but contends it cannot do so at the pace required in DNR's build out schedule. Also, WDC points out that it is unable to secure permanent financing for the project since lender's are uncertain if DNR will approve the build out schedule and allow construction to go forward or instead precipitously halt the construction. There have been no construction activities on the project since November 1988.
Findings Of Fact On September 23, 1983, Hollywood submitted a permit application to DNR for construction of the proposed project which is the subject matter of this proceeding. DNR designated that permit application as Permit Application 50-41. The proposed project is actually the first phase of a two-phase project, Phase II of which has already been permitted by DNR. Phase I, which is the subject of Permit Application 50-41, consists of an extension of existing Surf Road in the City of Hollywood, an extension of an existing asphalt boardwalk, construction of a parking area with landscaped island, swale, and associated lighting. The excavated fill removed from the site of Phase I is to be used in the construction of a dune which is encompassed within Phase II of the project. The properties on which Phase I and Phase II are to be constructed are owned by the City of Hollywood and are located seaward of the Coastal Construction Control Line and landward of the Erosion Control Line. The Summit Condominium is a condominium development located west of South Surf Road in the City of Hollywood, and is directly adjacent and contiguous to the property upon which the aforementioned project is to be constructed. Petitioner is the builder and developer of the Summit Condominium and, in addition, is the fee simple owner of approximately 15 units in that development. Phase I of the proposed project, which is the permit application at issue in this proceeding, provides for the construction of a 121-space public parking area which will be approximately 62 feet wide and 605 feet long, and will extend approximately 95 feet seaward of the Coastal Construction Control Line. The parking lot will be constructed with a six-inch limerock base over a six-inch crushed limerock subbase, and will be surfaced with a one and one-half- inch asphalt wearing course. The parking lot is designed with a definite landward slope, so that stormwater will sheet flow across the parking lot away from the dune system. There is no evidence of record in this proceeding which would in any way justify a conclusion that stormwater runoff from the parking lot area will have any adverse effect on the dune system seaward of the lot. Stormwater runoff once it has left the parking lot surface will be collected in a swale and drainage ditch system located landward of the paved parking lot surface. The drainage ditch will be composed of sandy material presently located on the site and is designed on a 1.2 to 1 slope. In addition, Wedelia is to be planted in and around the drainage ditch system in order to stabilize the slopes of the ditch. The ditch and swale system is designed to allow most stormwater runoff to percolate into the soil, with any excess being collected in the ditch itself and transmitted in a northerly direction. A drainage calculation study prepared in conjunction with this proceeding demonstrates that the drainage capacity for the proposed ditch meets minimum standards contained in the South Florida Building Code, as applied by the City of Hollywood. As the ditch fills with stormwater, the water will flow in a northerly, shore parallel direction to Jefferson Street, which is located north of both the proposed project and the Summit Condominium. From Jefferson Street, runoff from the project site will flow westerly to Highway A-1-A where an existing stormwater sewer system is located. If for some reason that system proves insufficient to handle runoff, the runoff will then travel across A-1-A into the intracoastal waterway. There is no competent evidence of record in this proceeding to demonstrate that stormwater runoff from the project site will, under any conditions, flow onto Petitioner's property. Phase I of the project has been designed to minimize the potential for the creation of aerodynamically or hydrodynamically propelled missiles in the event of a major storm. The asphalt surface of the parking lot is designed to break into chunks which will settle into the sand or water when exposed to wind and water forces. The parking meters are set four feet into the ground which reduces their potential to act as missiles, but even should the beach recede to the point where the meters are installed, evidence of record in this proceeding establishes that they will fall to the base of the eroded dune wall and will be washed out to sea rather than be propelled shoreward either by water or air. Various storm surge computer models for pre- and post-construction conditions at various locations on the property were performed. The result of these models shows that there will be no difference in impact on the beach dine system and adjacent property between the pre- and postconstruction profiles in the event of a ten-year storm. Further, computer models actually showed that there will be less erosion for the post-construction profile than for the preconstruction profile in the event of a twenty-year storm surge. In the event of a fifty-year or greater storm event, the beach profile for both pre- and postconstruction in the project area would be inundated, so that the impact of such a storm will be the same with or without the proposed construction. Evidence of record does, however, establish that based upon postconstruction conditions as proposed in the permit application it would take a greater storm to erode material from the postconstruction profile, thereby establishing that the proposed project will afford greater protection than existing topography. It appears from the record in this proceeding that Hollywood's Permit Application 50-41 is complete, and that DNR has in its possession all information necessary and required by law for the processing of the permit application. Engineering plans submitted in support of the application for Phase T have been signed and sealed by a professional engineer registered in the State of Florida.

The Issue The issue to be determined in these consolidated cases is whether the U.S. Army Corps of Engineers (“Corps”) and the City of Sarasota (“City”) (sometimes referred to as “the Applicants”) are entitled to the proposed joint coastal permit, public easement, and sovereign submerged lands use authorization (referred to collectively as “the Permit”) from the Department of Environmental Protection (“DEP”) and the Trustees of the Internal Improvement Trust Fund to dredge sand from Big Sarasota Pass and its ebb shoal and place the sand on the shoreline of Lido Key.
Findings Of Fact The Parties Petitioner Siesta Key Association, Inc. is a Florida Not for Profit Corporation, with its principal place of business in Sarasota. The organization has approximately 1,425 members and represents the interests of those who use and enjoy Siesta Key’s beach and waters. A substantial number of its members have substantial interests in the use of the beach and adjacent waters. Petitioner Michael S. Holderness is a resident and property owner on Siesta Key. Mr. Holderness has substantial interests in the protection of his property and the use of the beach at Siesta Key and adjacent waters. Petitioner Save Our Siesta Sands 2, Inc. is a Florida Not For Profit Corporation, with its principal place of business in Sarasota. The organization has over 700 members and was formed in opposition to the current dredging proposal. A substantial number of its members have substantial interests in the use of the beach at Siesta Key and adjacent waters. Petitioners Peter van Roekens and Diane Erne are residents and property owners on Siesta Key. They have substantial interests in the protection of their properties and the use of the beach at Siesta Key and adjacent waters. Respondent City of Sarasota is an incorporated municipality in Sarasota County. It is a co-applicant for the Permit. Respondent Corps is the federal agency responsible for the Lido Key Hurricane and Storm Damage Reduction Project first authorized by Congress in 1970. Under this Project, the Corps has conducted periodic maintenance, inlet dredging, surveys, and bypassing to protect Lido Key’s shoreline. The Corps is a co-applicant for the Permit. Respondent DEP is the Florida agency having the power and duty to protect Florida’s air and water resources and to administer and enforce the provisions of chapters 161, 373, and 403, Florida Statutes, and rules promulgated thereunder in Titles 62 and 62B of the Florida Administrative Code, which pertain to the permitting of construction activities in the coastal zone and in surface waters of the state. DEP acts as staff to the Board of Trustees of the Internal Improvement Trust Fund. Intervenor Lido Key Residents Association is a Florida Not for Profit Corporation incorporated in 1980 and with its principal place of business in Sarasota. The organization represents the interests of regular users of Lido Key Beach. A substantial number of its members have substantial interests in the use of the beach at Lido Key and adjacent waters. The Project Area Lido Key is a 2.6-mile-long, manmade barrier island constructed in the 1920s, located on the Gulf of Mexico and within the City of Sarasota. North of Lido Key is New Pass, a navigation channel that separates Lido Key from Longboat Key. South of Lido Key is Big Sarasota Pass and the ebb shoal of the pass. Further south is Siesta Key, a natural barrier island. Sediment Transport In the project area, sand generally drifts along the various shorelines from north to south. There can be sand drift to the north during some storm events, currents, and tides, but the net sand drift is to the south. It is sometimes called “downdrift.” Whatever downdrift conditions existed 100 years ago, they were substantially modified by the creation of Lido Key. For decades, the shoreline of Lido Key has been eroding. Since 1964, the Corps has periodically dredged New Pass to renourish the shoreline of Lido Key. The City has also used offshore sand to renourish Lido Key. These renourishment projects have not prevented relatively rapid erosion of the shoreline. A 2.4-mile-long segment of the shoreline of Lido Key has been designated by DEP as “critically eroded.” The Big Sarasota Pass ebb shoal has been growing and now has a volume of about 23 million cubic yards (“cy”) of sand. The growth of the ebb shoal is attributable to the renourishment projects that have placed over a million cy of sand on Lido Key and Longboat Key. The growth of the ebb shoal has likely been a factor in the southward migration of the main ebb channel of Big Sarasota Pass, closer to the northern shoreline of Siesta Key. Most of the west-facing shoreline at Siesta Key has experienced significant accretion. It is unusually wide for a Florida beach. It was named the best (“#1”) beach in the United States by “Dr. Beach,” Dr. Steven Leatherman, for 2011 and 2017. The Project The federally-authorized Lido Key Hurricane and Storm Damage Reduction Project includes the use of New Pass as a supplemental sand source for renourishing Lido Key. However, the use of New Pass is the subject of separate DEP permitting. The project at issue in this proceeding only involves the renourishment of Lido Key and is named “Lido Key Beach Renourishment and Groins.” The Applicants conducted a study of the ebb shoal to determine whether it could be used as a permanent sand source to renourish Lido Key. The study consisted of an environmental feasibility study and an inlet management program for Big Sarasota Pass and New Pass with alternative solutions. The application for the Permit was a response to this study. The proposed sand source or borrow areas are three dredge “cuts.” Cuts B and D are within the ebb shoal. Cut C extends through the ebb shoal and partly into Big Sarasota Pass. Cut C generally follows an existing “flood marginal channel.” The sand from the cuts would be placed along the central and southern 1.6 miles of Lido Key to fill a beach “template.” The design width of the renourished beach would be 80 feet. The initial placement would be wider than 80 feet to account for erosion. The Permit would have a duration of 15 years. The Applicants’ intent is to initially place 950,000 cy of sand on Lido Key. After the initial renourishment, sand would be dredged from one or more of the three designated cuts about every five years to replace the sand that eroded away, and would probably be on the scale of about 500,000 cy. The numerical modeling of the proposed project assumed the removal of up to 1.3 million cy of sand from the three cuts. One of DEP’s witnesses testified that the Permit authorizes the removal of up to 1.732 million cy of sand. The record does not support that testimony. The Applicants did not model the effects of dredging 1.732 million cy of sand from the ebb shoal and pass. There is insufficient evidence in the record to support an authorization to remove more than 1.3 million cy of sand. Although the total volume of sand in the three cuts is 1.732 million cy, it is reasonable for the dimensions of the cuts and the proposed easement that is based on these dimensions to contain more material than is authorized to be removed, so as to provide a margin to account for less-than-perfect dredging operations. Therefore, it is found that the Permit authorizes up to 1.3 million cy of sand to be removed from the designated borrow areas. The findings of fact and conclusions of law in this Recommended Order that address the expected impacts of the proposed project are based on this finding. The Permit also authorizes the construction of two rubble mound groins at the southern end of Lido Key to stabilize the beach and lengthen the time between renourishment events. The groins are designed to be semi-permeable so that they “leak” sand. There are no seagrasses in the renourishment area and mostly scattered and thin patches of seagrass near the dredge cuts. The Permit requires mitigation for the potential direct impacts to 1.68 acres of seagrasses. To offset these impacts, the Applicants propose to create 2.9 acres of seagrass habitat. The seagrass habitat would be established at the Rookery at Perico Seagrass Mitigation Basin in Manatee County, about 16 miles north of Big Sarasota Pass. The Permit incorporates the recommendations of the Florida Fish and Wildlife Conservation Commission regarding protections for turtles, nesting shorebirds, and manatees. The Permit requires regular monitoring to assess the effects of the project, and requires appropriate modifications if the project does not meet performance expectations. Project Engineering The Corps’ engineering analysis involved three elements: evaluating the historical context and the human influences on the regional system, developing a sediment budget, and using numerical modeling to analyze erosion and accretion trends near the project site. A principal objective of the engineering design for the borrow areas, sand placement, and groins was to avoid adverse effects on downdrift, especially downdrift to Siesta Key. The Corps developed a sediment budget for the “no action” and post-project scenarios. A sediment budget is a tool used to account for the sediment entering and leaving a geographic study area. The sediment budgets developed by the Corps are based on sound science and they are reliable for the purposes for which they were used. The post-project sediment budget shows there would be minimal or no loss of sediment transport to Siesta Key. Petitioners did not prepare a sediment budget to support their theory of adverse impact to Siesta Key. Petitioners object to the engineering materials in the Permit application because they were not certified by a Florida registered professional engineer. DEP does not require a Florida professional engineer’s certification for engineering work submitted by the Corps. As explained in the Conclusions of Law, Florida cannot impose licensing conditions on federal engineers. Ebb Shoal Equilibrium Petitioners’ witness, Dr. Walton, developed a formula to estimate ebb shoal volume equilibrium, or the size that an ebb shoal will tend to reach and maintain, taking into account bathymetry, wave energy, tides, adjacent shorelines, and related factors. In an article entitled “Use of Outer Bars of Inlets as Sources of Beach Nourishment Material,” Dr. Walton calculated the ebb shoal equilibrium volume for the Big Sarasota Pass ebb shoal as between 6 and 10 million cy of sand. The ebb shoal has been growing and is now about 23 million cy of sand, which is well in excess of its probable equilibrium volume. The volume of sand proposed to be removed from the ebb shoal is only about six percent of the overall ebb shoal volume. Dr. Walton’s study of the use of ebb shoals as sand sources for renourishment projects supports the efficacy of the proposed project. Modeling Morphological Trends The Corps used a combined hydrodynamic and sediment transport computer model called the Coastal Modeling System, Version 4 (“CMS”) to analyze the probable effects of the proposed project. The CMS model was specifically developed to represent tidal inlet processes. It has been used by the Corps to analyze a number of coastal projects. Dr. Walton opined that the CMS model was inappropriate for analyzing this project because it is a two-dimensional model that is incapable of accounting for all types of currents and waves. However, a two-dimensional model is appropriate for a shallow and well-mixed system like Big Sarasota Pass. Dr. Walton’s lack of experience with the CMS model and with any three-dimensional sediment transport model reduced the weight of his testimony on this point. Petitioners contend that the CMS model was not properly calibrated or verified. Calibration involves adjustments to a model so that its predictions are in line with known conditions. Verification is the test of a model’s ability to predict a different set of known conditions. For calibrating the hydrodynamic portion of the model, the Corps used measurements of water levels and currents collected in 2006. The model showed a 90-percent correlation with water surface elevation and 87-percent correlation to velocity. Dr. Walton believes a model should exhibit a 95-percent correlation for calibration. However, that opinion is not generally accepted in the modeling community. Model verification, as described by Dr. Walton, is generally desirable for all types of modeling, but not always practical for some types of modeling. A second set of field data is not always available or practical to produce for a verification step. In this case, there was only one set of sea floor elevations available for verification of the CMS model. It is the practice of DEP in the permitting process to accept and consider sediment transport modeling results that have not been verified in the manner described by Dr. Walton. The Corps described a second calibration of the CMS model, or “test of model skill,” as an evaluation of how well the CMS model’s sediment transport predictions (morphological changes) compared to Light Detection and Ranging (“LIDAR”) data collected in 2004. The CMS model successfully reproduced the patterns of erosion and sediment deposition within the area of focus. Petitioners’ expert, Dr. Luther, testified that, over the model domain, the CMS model predictions differed substantially from LIDAR data and believes the discrepancies between the model’s predictions and the LIDAR data make the model’s predictions unreliable. Modeling sediment transport is a relatively new tool for evaluating the potential impacts of a beach renourishment project. Renourishment projects have been planned, permitted, and carried out for decades without the use of sediment transport models. Now, modeling is being used to add information to the decision-making process. The modeling does not replace other information, such as historical data, surveys, and sediment budgets, which were heretofore used without modeling to make permit decisions. Sediment transport is a complex process involving many highly variable influences. It is difficult to predict where all the grains of sand will go. Sediment transport modeling has not advanced to the point which allows it to predict with precision the topography of the sea floor at thousands of LIDAR points. However, the CMS model is still useful to coastal engineers for describing expected trends of accretion and erosion in areas of interest. This was demonstrated by the model’s accurate replication of known features of the Big Sarasota Pass and ebb shoal, such as the flood marginal channels and the bypassing bars. The CMS model’s ability to predict morphological trends assisted the Applicants and DEP to compare the expected impacts associated with alternative borrow locations on the ebb shoal and pass, wave characteristics, and sediment transport pathways. Together with other data and analyses, the results of the CMS model support a finding that the proposed dredging and renourishment would not cause significant adverse impacts. The Applicants extensively analyzed sediment transport pathways and the effects of alternative borrow areas on sediment transport to Siesta Key. Petitioners’ hypothesis is not supported by engineering studies of equivalent weight. The more persuasive evidence indicates that sediment transport to downdrift beaches would not be reduced and might even be increased because sediment now locked in the ebb shoal would reenter the sediment transport pathways. In addition, the proposed dredging may halt the southward migration of the main ebb channel of Big Sarasota Pass, and thereby reduce erosive forces on the interior shoreline of north Siesta Key. Wave Energy Petitioners assert that the proposed dredging would result in increased wave energy on Siesta Key because the diminished ebb shoal would no longer serve as a natural buffer against wave energy from storms. They conducted no studies or calculations to support this assertion. Because the proposed dredging would remove a small percentage of the total ebb shoal volume, the ebb shoal would remain a protective barrier for Siesta Key. Wave energy reaching the shorelines along Big Sarasota Pass or within Sarasota Bay would continue to be substantially reduced by the ebb shoal. The predicted increase in wave energy that would occur as a result of the project could increase the choppiness of waters, but would not materially increase the potential for wave-related erosion. Petitioners conducted no studies and made no calculations of their own to support their allegation that the project would significantly increase the potential for damage to property or structures on Siesta Key due to increased wave energy. To the extent that Petitioners’ expert coastal engineer opined otherwise, it was an educated guess and insufficient to rebut the Applicants’ prima facie case on the subject of wave energy. Groins Petitioners contend that the two proposed groins would adversely impact the beaches of Siesta Key because the groins would capture sand that would otherwise drift south and benefit Siesta Key. However, the preponderance of the evidence shows the groins would not extend into or obstruct the sand “stream” waterward of the renourished beach. The historic use of groins to capture downdrift resulted in adverse impacts to adjacent beaches. However, the use of groins in conjunction with beach renourishment to stabilize a renourished beach and without obstructing downdrift is an accepted practice in coastal engineering. The proposed groins would not obstruct longshore sediment transport and, therefore, would not interfere with downdrift to Siesta Key. Public Interest - General Section 373.414(1) requires an applicant to provide reasonable assurance that state water quality standards will not be violated, and reasonable assurance that a proposed activity is not contrary to the public interest. However, if the proposed activity significantly degrades or is within an Outstanding Florida Water (“OFW”), the applicant must provide reasonable assurance that the proposed activity will be clearly in the public interest. Sarasota Bay, including Big Sarasota Pass and portions of Lido Key, have been designated as an OFW. Therefore, the Applicants must demonstrate that the proposed project is clearly in the public interest. In determining whether an activity is clearly in the public interest, section 373.414(1)(a) requires DEP to consider and balance seven factors: Whether the activity will adversely affect the public health, safety, or welfare or the property of others; Whether the activity will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; Whether the activity will be of a temporary or permanent nature; Whether the activity will adversely affect or will enhance significant historical and archaeological resources under the provisions of section 267.061; and The current condition and relative value of functions being performed by areas affected by the proposed activity. DEP determined that the project is clearly in the public interest because it would improve public safety by providing protection to Lido Key upland structures from storm damage and flooding, protect and enhance wildlife habitat, and provide beach-related recreational opportunities; and it would create these public benefits without causing adverse impacts. Public Interest - Safety Petitioners contend that the proposed project would adversely affect public health, safety, welfare, or the property of others because it would interrupt downdrift and substantially reduce the storm protection provided by the ebb shoal. As found above, the preponderance of the evidence does not support this contention. Public Interest - Conservation of Fish and Wildlife Petitioners contend that the proposed project would adversely affect the conservation of fish and wildlife, including endangered or threatened species. The Permit application materials provided evidence that the proposed project would have no effects, or only minimal temporary effects, on water quality, temperature, salinity, nutrients, turbidity, habitat, and other environmental factors. That was sufficient as a prima facie showing that the project would not adversely affect the conservation of fish and wildlife because, if environmental factors are not changed, it logically follows that there should be no adverse impacts to fish and wildlife. Therefore, as explained in the Conclusions of Law, the burden shifted to Petitioners to present evidence to show that adverse effects to fish and wildlife would occur. It was not enough for Petitioners to simply contend that certain fish species were not adequately addressed in the application materials. With the exception of Dr. Gilmore’s field investigation related to the spotted seatrout, Petitioners conducted no studies or field work of their own to support their allegations of adverse impacts to fish and wildlife. Dr. Gilmore discovered that spotted seatrout were spawning in Big Sarasota Pass. Such spawning sites are not common, are used repeatedly, and are important to the conservation of the species. Spotted seatrout spawn from April through September. The record does not show that the Florida Fish and Wildlife Conservation Commission, the U.S. Fish and Wildlife Service, or the National Marine Fisheries Service were aware that Big Sarasota Pass was a spawning area for spotted seatrout, or considered this fact when commenting on the project. The spotted seatrout is not a threatened or endangered species, but DEP is required to consider and prevent adverse impacts to non-listed fish species, as well as recreational fishing and marine productivity. If the proposed project would destroy a spotted seatrout spawning area, that is a strong negative in the balancing of public interest factors. The Applicants do not propose mitigation for adverse impacts to spotted seatrout spawning. Seagrass sites close to the spawning area are used by post-larval spotted seatrout for refuge. The likely seagrass nursery sites for seatrout spawning in Big Sarasota Pass are depicted in SOSS2 Exhibit 77. The proposed seagrass mitigation at the Perico Rookery Seagrass Mitigation Basin, over 16 miles away, would not offset a loss of this refuge function because it is not suitable as a refuge for post-larval spotted seatrout. The spawning season for spotted seatrout occurs during the same months as turtle nesting season, and DEP argued that the turtle protection conditions in the Permit to limit lighting and prohibit nighttime work, would also prevent adverse impacts to the spotted seatrout. However, spotted seatrout spawning is also threatened by turbidity and sedimentation in the spawning area and adjacent seagrasses. The spotted seatrout spawning area is in the area where dredge Cut B is located. If Cut B were dredged during the spawning season, it would likely disrupt or destroy the spawning site. Reasonable assurance that the proposed project would not disrupt or destroy the spawning site requires that Cut B not be dredged during the spawning season. Seagrasses that are likely to provide refuge to post- larval seatrout are near the most eastern 1,200 feet of Cut C. Reasonable assurance that the proposed project would not disrupt or destroy the refuge function requires that the most eastern 1,200 feet of cut C not be dredged during the spawning season. In summary, the proposed project would adversely affect the conservation of fish and wildlife unless dredging was restricted during the spotted seatrout spawning season, as described above. Public Interest – Navigation, Flow of Water, and Erosion Petitioners contend that the proposed project would adversely affect navigation, the flow of water, and would cause harmful erosion to Siesta Key, but Petitioners conducted no studies or calculations to support this assertion. The preponderance of the evidence shows that no such adverse impacts would occur. Public Interest – Recreational Values Petitioners contend that the proposed project would adversely affect fisheries and associated recreation because of harm to spotted seatrout and other fish species. As found above, the preponderance of the evidence shows the project would adversely affect the spotted seatrout, an important recreational fish species, unless dredging was restricted during the spawning season. Public Interest - Value of Functions Petitioners contend that the proposed project would adversely affect the current condition and relative value of functions being performed by areas affected by the proposed project because dynamic inlet system would be disrupted. As found above, the preponderance of the evidence shows the project would not adversely affect the coastal system. However, it would adversely affect the spotted seatrout spawning and refuge functions provided by Big Sarasota Pass unless dredging was restricted during the spawning season. Mitigation If a balancing of the public interest factors in section 373.414(1)(a) results in a determination that a proposed project is not in the public interest, section 373.414(1)(b) provides that DEP must consider mitigation offered to offset the adverse impacts. Although the Perico Rookery at Seagrass Mitigation Basin is within the OFW and the same drainage basin, it does not fully offset the adverse impacts likely to be caused by the proposed project. The mitigation would not offset the loss of spotted seatrout spawning and refuge functions. The mitigation for the loss of spotted seatrout spawning and refuge functions is unnecessary if the impacts are avoided by restricting dredging during the spawning season as described above. Design Modifications Petitioners contend that the Applicants did not evaluate the alternative of taking sand from offshore borrow areas for the renourishment. The record shows otherwise. Furthermore, as explained in the Conclusions of Law, the Applicants were not required to address design modifications other than alternative locations for taking sand from the ebb shoal and Big Sarasota Pass. Consistency with the Coastal Zone Management Program Petitioners contend that DEP failed to properly review the Permit for consistency with the Florida Coastal Zone Management Program (“FCZMP”), because DEP failed to obtain an affirmative statement from Sarasota County that the proposed project is consistent with the Sarasota County Comprehensive Plan. The State Clearinghouse is an office within DEP that coordinates the review of coastal permit applications by numerous agencies for consistency with the FCZMP. It is the practice of the State Clearinghouse to treat a lack of comment by an agency as a determination of consistency by the agency. With respect to this particular project, the State Clearinghouse provided a copy of the joint coastal permit application to the Southwest Florida Regional Planning Council (“SWFRPC”) for comments regarding consistency with local government comprehensive plans. SWFRPC submitted no comments. In a letter dated June 26, 2015, the State Clearinghouse reported to the Corps that “at this stage, the proposed federal action is consistent with the [FCZMP].” In a written “peer review” of the proposed project produced by the Sarasota Environmental Planning Department in October 2015, some concerns were expressed, but no mention was made of inconsistency with the Sarasota County Comprehensive Plan. Sarasota County sent a letter to DEP, dated August 24, 2016, in which it requested that the Corps prepare an Environmental Impact Statement (“EIS”) for the project. Sarasota County did not indicate in its letter to DEP that the proposed project is inconsistent with any policy of the Sarasota County Comprehensive Plan. Petitioners assert that the proposed project would be inconsistent with an environmental policy of the Sarasota County Comprehensive Plan that Petitioners interpret as prohibiting the proposed dredging. The record contains no evidence that Sarasota County believes the proposed project is inconsistent with this particular policy or any other policy of its comprehensive plan.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that DEP issue a final order approving the proposed agency actions, but only if the joint coastal permit is modified to prohibit dredging operations in Cut B and the most eastern 1,200 feet of Cut C during April through September. If this modification is not made, it is recommended that the proposed agency actions be DENIED; and The joint coastal permit be modified to clarify that it authorizes the removal of up to 1.3 million cy of sand.

The Issue Whether the Petitioners, and each of them, have standing to bring the instant action before the Division of Administrative Hearings. Whether the 5500 North Corporation has meets the requirements set forth in Section 161.053, Florida Statutes, and Rule 16B-33, Florida Administrative Code, for obtaining a permit to construct a structure seaward to the coastal construction control line (CCCL).
Findings Of Fact The Department of Environmental Protection, f/k/a Department of Natural Resources, is the state agency charged with the responsibility of regulating coastal construction under Chapter 161, Florida Statutes. 5500 North Corporation (Respondent/Applicant) is the owner of the property located at 5600 North Atlantic Avenue, Cocoa Beach, Brevard County, Florida 32931. 5500 North Corporation submitted an application for a coastal construction control line (CCCL) permit to build on the vacant portion of its property, a seven (7) story building, along with required access drives and parking, as an addition to the Cocoa Beach Days Inn Hotel complex. The site of the proposed Days Inn Tower fronts on the Atlantic Ocean and is located three (3) miles south of Port Canaveral, near DNR survey monument R-16. The application and attached document were compiled and submitted to the Department of Environmental Protection by Plata Engineering, Inc., and consisted of the following documents: Application to the Department for the proposed construction of the building, consisting of three pages, front and back, six pages total. A legal description of the property, and a Warranty Deed for the property demonstrating ownership in 5500 North Corporation. Reduced certified survey of the site, showing control lines and other required information. Reduced Site Plan prepared by Plata Engineering, Inc. Section C - which is a section through the site plan, showing the dune configuration in relation to the proposed building and the construction control lines. A depiction of a section through the proposed building and some of its structural elements. Full size drawing of the proposed site. Turtle assessments form with attached lighting specifications of the manufacturer, and aerial of the site attached. Structural Design Calculations. Complete set of Building Plans, dealing with floor planning, and the structural elements of the calculations that were submitted with the structural calculations. The application was deemed complete, and on May 20, 1993, the Department issued a proposed Final Order issuing Permit Number BE-760 for the proposed structure. Standing of Petitioners Petitioner, Carole Pope, resides in the City of Rockledge, Brevard County, Florida. She is the owner of Lot 11, Block 101 of the platted subdivision known as Avon-By-The Sea which is located in unincorporated Brevard County, north of the existing north boundary of the City of Cocoa Beach. A duplex dwelling unit is located on the parcel. Petitioner occupies one unit annually during the summer. Petitioner Pope's property is not adjacent to the property where the proposed Days Inn Tower is to be located. The property is located approximately three blocks directly north of the proposed building and measures 475 feet east- west by 50 feet north-south and is bounded on the east by the Atlantic Ocean. Petitioners, Hugh and Cora Harris, own property located at Lot 13 of replat of Blocks 104 and 105, Avon-by-the Sea, in the unincorporated land of Brevard County, which borders on the City of Cocoa Beach. Petitioners' property is located across Young Avenue, and north of the property owned by 5500 North Corporation. The Harris's property contains a single family dwelling unit and is adjacent to the property were the proposed Days Inn Tower is to be located. Petitioners, Patricia A. and Eugene A. Wojewoda, own a unit at the Cocoa Beach Towers, a multi-family condominium, which is located north of the property owned by 5500 North Corporation, across Young Avenue, in the City of Cocoa Beach. The Wojewoda's unit is located on property which is adjacent to the property where the proposed Days Inn Tower is to located. Petitioners Wojewodas are Real Estate Brokers and owners of Professional Touch Realty, Inc. One of their four offices is located at 108 Young Avenue, immediately across the street and north of the subject property. Petitioners, Howard and Martha Crusey, own a unit, which they rent out, in the Cocoa Beach Towers, which is located north and adjacent to the property owned by 5500 North Corporation. Petitioners reside at 430 Johnson Avenue in Cape Canaveral, Florida. The Department sent out a notice for public comment to each of the immediate adjacent property owners. Existing Uniform and Continuous Line of Construction As part of the application process, the Department made a determination of the existing line of uniform and continuous construction. The existing line of uniform and continuous construction is a theoretical line that goes from the most seaward extent of the two adjacent structures, where adjacent structures exist, and extends north and south along the seaward edge of the structures. In the instant case, there is historical development of major habitable structures on either side of the parcel for which the proposed building is being constructed and which are co-terminus with the prior CCCL. The footprint of the proposed Days Inn Tower does not extend seaward of the existing uniform and continuous line of construction, although a new structure (Discovery Beach) north of the Cocoa Beach Towers has been constructed landward of the current CCCL. The existing structures, which form the existing line of uniform and continuous construction, have not been unduly affected by erosion. The property was purchased by 5500 North Corporation in 1988. The property was commercially developed with the existing hotel buildings between 1959 and 1962, and the site has been operated as a hotel since that time. The footprint of the building was set by the engineers based on the parking requirements of the City of Cocoa Beach, and environmental concerns. It was determined that if the parking were located on the seaward side of the building, there would be drainage problems, and the need for a storm water treatment system for the parking lot. With the parking lot located landward of the proposed building, there will be no drain off to the side areas, but rather drain off would be to the middle of the property where the exfiltration system is located. The parking lot located landward of the proposed building meets the City of Cocoa Beach parking requirements and the drainage requirements. When siting the footprint of the proposed building, the engineers also took into consideration the fact that if the parking were located on the seaward side of the proposed building, the headlights would shine out to the beach and possibly impact sea turtles nesting. The applicants stated that construction seaward of the control line or 50-foot setback is considered necessary for reasonable use of the property, for the following reasons: The proposed building is basically an addition to a completion of the original concept of the overall hotel complex that was never completed in the past due to either financial or room availability need. The proposed placement seaward of the CCCL can be attributed to the configuration of the existing on-site buildings and the require- ment to satisfy the City of Cocoa Beach's extensive parking and limited access point requirements that have been subjected to this proposed site development. Please note that the proposed building is not being placed seaward of the existing line of continuous construction that has been established by the adjacent buildings to the north and the south. The Department determines necessity based upon the impacts the proposed structure will have on the active beach, and the dune system, and the neighborhood properties including the subject property, how the property is zoned, and whether it is situated behind the existing continuous line of construction. It is the Department's opinion that if the proposed building is in compliance with the standards established in Chapter 16B-33, F.A.C., the necessity of the proposed building has been justified. Impacts to the Beach-Dune System The greater weight of evidence supports the conclusion that the shoreline fronting the site of the proposed Days Inn Tower is stable. This section of the coastline has historically been accretional, and still continues to be accretional. There exists adequate evidence of current littoral trends. There exists accepted methodologies for determining evidence of expected wind, wave, hydrostatic and hydrodynamic forces associated with the design storm event which was presented in 5500 North Corporation's application for CCCL permit. Based on the 1989 Brevard County Study conducted by Olsen and Associates, Inc., there is no erosion at the location of the proposed building, instead the shoreline is prograding seaward instead of landward. Therefore, the shoreline is at least stable or accretional. Based on its in-house analysis, the Department of Environmental Protection conservatively adopted an erosion rate of one foot per year, which is considered a relatively minor erosion rate. Based on the Department of Environmental Protection's projection of the erosion for the area being one foot per year, the location of the proposed building lies well in excess of 200 feet landward of the thirty-year seasonal high water line. Although the proposed structure extends 118 feet seaward of the CCCL, the setback of the proposed building from the existing dune line is significant; therefore, there was no evidence of a threat of impact on the beach, to the beach or dune system as a result of the construction at the specific site. There are existing devices (i.e., an existing fence on the property which funnels people into boardwalks so that people cannot walk uncontrolled on the beach dune system) implemented in Brevard County and specifically on the site which will help manage people impacts as well. The setback between the dune and the proposed construction qualitatively relates to the ability of the site to recover after a one-hundred year storm. If a structure is located too far seaward, either immediately adjacent to or on top of the dune, it would inhibit the natural storm recovery process. The proposed building is set a significant distance landward of the dune formation itself, so there will be adequate room for the dune to recover in the future should there be a one-hundred year storm event. The proposed structure is located at a sufficient distance landward of the beach-dune system to permit natural shoreline fluctuations and to preserve the dune stability and the natural recovery following storm induced erosion. The proposed construction will not have a cumulative impact that will threaten the beach or dune system or its recovery potential following a major storm event. low. Impacts to Adjacent Property Owners The probability of potential impacts to adjacent property owners is One reason the proposed building will not have adverse impacts to adjacent properties is that the proposed building is located significantly landward, and does not go further seaward than the existing line of construction. The adjacent buildings were constructed landward of the previous CCCL. The nature of the design associated with the particular project or the structural components of the design also minimize the impact to the parcel and to adjacent parcels. The first feature of the design of the proposed building is that the major habitable floors of the building are above the elevation of the one- hundred year storm and wave activity on top of the storm surge, so they will not be impacted by the water height or the wave activity of the storm. The second feature of the design of the proposed building is that everything below the habitable floors is designed to break away and lie down during any impact by wave activity, which allows the storm to go through the building rather than having those forces exerted on the building itself. The frangible driveway is designed so that the individual stones will fall as the grade falls, and most of them will end up buried in the event of a storm. The third feature of the design of the proposed building is that the building is elevated on a pile foundation which is sunk to a depth which is sufficient to accommodate for the anticipated erosion of a one-hundred year storm, and the pile caps are sunk well into the ground so that they do not contribute to erosion. Therefore, the building has been designed to withstand the one-hundred year storm, and the dynamics of the storm are allowed to go through the building and to be dissipated, in contrast to endangering the building or endangering adjacent properties. Due to the fact that the proposed building is "super-elevated and the portions that are actually impacted by the one-hundred year storm being frangible," the proposed building will not impact the adjacent properties. The proposed Days Inn Tower would serve to protect the adjacent Cocoa Beach Towers, and Petitioner Harris's property, by blocking the impact of a storm coming from the southeast. The proposed structure is designed so as to minimize any expected adverse impact on the beach dune system or adjacent properties or structures and is designed consistent with Section 16B-33.005, Florida Administrative Code. The proposed building meets the requirements of Chapter 161, Chapter 16B-33, Florida Administrative Code. Structural Design of Proposed Building The applicant provided adequate engineering data to the Department concerning the construction design of the building. The structure is designed in accordance with the minimum building code adopted for the area pursuant to Section 553.70-553.895, Florida Statutes. The proposed building is designed in accordance with the local code, and, in the opinion of the structural engineer who designed the building, either meets or exceeds the required codes. The proposed building is designed in accordance with Section 6, American National Standards/American Society of Civil Engineering 7-88 (July 1990) "Minimum Design Loads for Buildings and Other Structures", and has a minimum basic wind speed of 110 miles per hour. The proposed building is designed so that the building and its components will not become airborne missiles. The plans for the windows and doors require that they meet the 110 miles per hour wind loads. The proposed building is made of concrete reinforced masonry, and does not have bricks or attached masonry which could detach in a storm and become airborne. There are no substantial walls or partitions to be constructed below the level of the first finished floor, except for the elevator and stairs, seaward of the CCCL. The walls on the first floor are frangible walls which are designed to resist the 110 mile per hour wind pressure, but they lie down or collapse into the erosion hole created under wave surge pressure. The frangible walls are made of 4-inch thick concrete with reinforcing rods inside them, and are cut into 4 foot by 4 foot panels. The Department of Environmental Protection requires that any walls constructed below the one-hundred year storm surge plus storm wave elevations be frangible walls. The structural design considered the hydrodynamic loads which would be expected under the conditions of a one-hundred year storm event. The calculation for wave forces on building foundations and building superstructures is based on minimum criteria and methods given in professionally recognized documents accepted by the Bureau of Coastal Engineering and Regulation with the Department. The structural design considered hydrostatic loads which would be expected under the conditions of maximum water height associated with a one- hundred year storm event. The calculations for hydrostatic loads considered the maximum water pressure resulting from a fully peaked, breaking wave superimposed on the design storm surge. Both free and confined hydrostatic loads were considered in the design calculations. Hydrostatic loads which are confined were determined using the maximum elevation to which the confined water would fully rise if unconfined. Vertical hydrostatic loads were considered as forces acting both vertically downward and upward; however, there is no action upward because the maximum water level is at midlevel of the first floor and does not reach the second floor. The structural design considered the hydrodynamic loads which would be expected under the conditions of a one-hundred year storm event. The calculations for hydrodynamic loads considered the maximum water pressure resulting from the motion of the water mass associated with a one- hundred year storm event. Full intensity loading was applied on all structural surfaces above the design grade which would effect the flow velocities, which are above the first floor and are not reached by the wave surge. The proposed building is elevated on, and securely anchored to, an adequate pile foundation in such a manner as to locate the building support structure above the design breaking wave crests or wave uprush as superimposed on the storm surge with dynamic wave set up of one-hundred year storm. The piling foundation is designed to withstand anticipated erosion, scour, and loads resulting form a one-hundred year storm, including wind, wave, hydrostatic and hydrodynamic forces, and the pile caps are located below the erosion line as indicated by the Department's information and graphs. The elevation of the soil surface used in the calculation design grade is less than that which would result from the anticipated beach and dune erosion due to the one-hundred year storm event. The erosion calculations for foundation design account for all vertical and lateral erosions and scour producing forces. The pile caps are set below the design grade which includes localized scour, and are designed for the erosion of soil during the one-hundred year storm event. The piles are driven to a penetration which achieves adequate bearing capacity taking into consideration the anticipated loss of soil above the design grade, based on information provided by the geotechnical engineer's recommendation and the Department's requirements. The design plans and specifications submitted as part of the permit application for the proposed Days Inn Tower are in compliance with the standards established in Rules 16B-33, Florida Administrative Code. Turtle Impacts There is a two prong test which the proposed structure must meet to determine if the proposed building would have an adverse impact on nesting sea turtles. First, the proposed structure must not occupy marine turtle habitat, and second, the proposed structure's lighting must be adequate to eliminate adverse impacts to marine turtles. The effects of pedestrian traffic or flashlights on the beach are not considered by the Department when reviewing a permit application for adverse impacts to the marine turtles. The proposed building is sited significantly landward of the nesting beach, which is evidenced by the 75-foot wide dune stretch; therefore, it is not anticipated that the structure will result in any direct mortality of any marine turtle, nor would the building result in the degradation of the marine turtle nesting habitat. The proposed seven story structure will not occupy marine turtle habitat. The permit requirement to do dune restorative work, proposed by the Department, enhances the marine turtle habitat by further building the dune and enhancing the dune. Although the turtles do not nest beyond the dune crest, the dune is an integral part of protecting the habitat. There is a potential that the building, due to its height, could enhance marine turtle nesting habitat by blocking out the ambient glow from the City of Cocoa Beach which would create a dark beach directly in front of the proposed structure which could attract nesting. The applicant submitted a lighting plan to the Department which complied with the guidelines that are established in the information form entitled "Assessment to reduce impacts to marine turtles for lighting to reduce adverse impacts associated with coastal lighting." There are two main components of the lighting plan associated with the proposed building: the parking lot lights and the structural lighting. The parking lot lighting is designed as low-level Ballard-style lighting which is only 48 inches above the grade and emits light in a downward direction which will not be directly visible from the beach. The parking lot lighting design is the type recommended by the Department for parking lots, and is a good lighting design. The Department also recommends that an applicant plant hedges or landscape features to block out parking lights. The applicant is proposing to plant hedges in front of the 18 parking spaces that are on the seaward side of the proposed building. The structural lighting plan does have lighting on the seaward facade of the proposed building, which is not recommended by the Department, but the lights are designed to eliminate or significantly reduce the impact to marine turtles. The lights consist of canister, shielded, down-casting lights on the balconies which house a yellow bug lamp which is less impactive to turtles, and which is acceptable to the Department. The Department issued an approval letter regarding the proposed building to the project engineer which contained permit conditions for the protection of the marine turtles in association with the project. The permit conditions are as follows: No construction, operation, transportation or storage of equipment or materials is authorized seaward of the existing chain link fence located approximately 175 feet seaward of the coastal construction control line. No temporary lighting of the construction area is authorized at any time during the marine turtle nesting season (March 1 through October 31). All permanent exterior lighting shall be installed and maintained as depicted in the approved lighting schematic. No additional permanent exterior lighting is authorized. c All windows and glass doors visible from any point on the beach must be tinted to a transmittance value (light transmission form inside to outside) of 45% or less through the use of tinted glass or window film. Pursuant to the Department's requirements, the proposed construction will not have an adverse impact on nesting sea turtles, their hatchlings, or their habitat. Vegetation Impacts The vegetation patch on the dune system is approximately seventy five feet wide under today's conditions, and is probably growing to some degree. The vegetation system is basically comprised of a low-level dune which is planted both naturally and artificially with indigenous, salt-tolerant type vegetation, and sea oats. The existing line of construction which the proposed building is set behind is well landward of the zone of indigenous vegetation. Special condition #4 contained in the permit issued by the Department requires the applicant to convert some of the existing sodded area between the vegetation limits and the proposed construction to plantings with indigenous vegetation, which will serve to enhance the dune system. The native beach vegetation will be adequately protected by the permit conditions, given the location of the construction. Local Government Approvals On June 3, 1992, the Cocoa Beach Board of Adjustment granted a variance to the CCCL to the 5500 North Corporation for construction of the proposed building. Challenges to decisions of the City's Board of Adjustment is to the circuit court. In the instant case, the time for challenging the decision of the Board has expired. The City of Cocoa Beach Planning Board has the authority to approve site plans for site specific construction. The City's Planning Board has the responsibility of ensuring that the site plan conforms with the Comprehensive Plan and to recommend changes, if needed, to the City Commission. On July 13, 1992, the Cocoa Beach Planning Board voted to approve the site plan for the proposed building submitted by the 5500 North Corporation. The decision of the Planning Board granting approval of the 5500 North Corporation's site plan showed part or all of the building was seaward of the CCCL. The Petitioners did not file an appeal of the Planning Board's decision with the City Commission. Nor did they challenge the Planning Board's action in the circuit court. The 5500 North Corporation was not required to apply to the city commission for an amendment to the Cocoa Beach Comprehensive Plan in order to permit the proposed hotel tower to be located in the designated high hazard area. On July 6, 1993, the Building Official issued a building construction permit to the 5500 North Corporation for the proposed building, which has been subsequently extended for an unknown period of time. There are no other permits or local government requirements which have not been met by 5500 North Corporation. The applicant submitted written evidence to the Department from the City of Cocoa Beach, who has jurisdiction over the project, which stated that the project does not contravene local setback requirements, or zoning and building codes.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department of Environmental Protection issue Permit Number BE-760 to the 5500 North Corporation, subject to the conditions proposed in the proposed Final Order. DONE and ENTERED this 24th day of March, 1994, in Tallahassee, Florida. DANIEL M.

The Issue The issue in this case is whether a beach house petitioners plan to build in south Walton County was already under construction, within the meaning of Section 161.053(7), Florida Statutes (1981) and Rule 16B-33.04(1), Florida Administrative Code, at the time the current coastal construction control line took effect there.
Findings Of Fact In October of 1982, the petitioners acquired a lot in south Walton County, on the north shore of the Gulf of Mexico. Even before the purchase, Mr. Wiese had been in touch with respondent's personnel, who apprised him of the imminence of the adoption of the new (now current) coastal construction control line, at that time already proposed for Walton County. The former coastal construction control line was considerably seaward of the current line, which became effective on December 29, 1982. Petitioners, who have built some seven houses, drew plans for a house to be built on their Walton County lot one foot landward of the old coastal construction control line. They applied for and obtained the necessary county building permit. They contracted for grading on site, which took place on November 27, 1982. In the course of this work, the landward face of the sand dune was disturbed and petitioners realized that, if they were to build so close to the water, a wall or something like a wall would have to be erected and buttressed to keep the sand dune from migrating under or into their beach house. They determined that the plans were inadequate as drawn. Mr. Wiese nevertheless arranged for one Al Christopher to bring two poles to the site and place one of them upright in the sand. When asked at hearing how long the two poles Mr. Christopher delivered to the site were, Mr. Wiese said he did not know. After Mr. Christopher began, petitioners did not ask him to desist either with bringing pilings to the site or with placing them in the ground. Mr. Christopher evidently did what he was asked to do, before he ever began working with the poles. Before the single pile was placed, batter boards were used to locate the perimeters planned for the building. Batter boards are temporary markers which are removed once the foundation is in place. In constructing piling foundations for beach houses along the gulf coast, in this part of Florida if not elsewhere, the ordinary sequence is to bring all foundation piles to the site before bringing the equipment necessary to install all the piles at once. This makes for efficient use of expensive machinery, and is virtually always done. One of the Wieses' neighbors, fearing that the new coastal construction control line would take effect last fall arranged for a single pile to be driven, but his project was well underway by the time the new coastal construction control line did in fact take effect. As late as March of this year, Mr. Wiese checked with a Texas supplier to see if foundation piles would be available for the project. The plans drawn before the grading of November 27, 1982, called for a foundation of 37 piles, each of which was to be 45 feet long. No horizontal members nor bracing of any kind was contemplated for the foundation. The foundation piles were to be put so close together that it would have been impractical to bring heavy equipment in to do the grading after they were in place. The idea in leveling the ground was to prepare it so a concrete slab could be poured to serve as a parking surface underneath the beach house. Under both the plans originally drawn and the plans under which petitioners now hope to proceed the parking surface itself is not expected to have a structural function, Mr. Wiese's testimony to the contrary notwithstanding. Once petitioners were persuaded that the project needed "reengineering," they diligently sought out expert assistance and new foundation plans were eventually drawn to their satisfaction. Petitioners' efforts took place on a regular, if not a daily basis, but consisted in large part of finding the right people for the "reengineering" job. The plans which petitioners propose to use were stamped with the final engineer's seal on March 3, 1983, more than two months after the current coastal construction control line took effect.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That respondent deny petitioners' beach house project grandfathered status, and apply the coastal construction control line adopted for Walton County on December 29, 1982, in any agency action regarding the project.

Findings Of Fact Because of a 1984 Thanksgiving Day storm which inflicted damage in coastal areas, Barry Manson-Hing, an area engineer employed by the Department, issued emergency coastal construction permits from a temporary office in the Vero Beach Administration Building. On December 3, 1984, Respondent sought an emergency permit to allow him to place sand and sand-filled bags on his coastal property at 3755 Ocean Drive, Vero Beach, Florida. Respondent asked Mr. Manson-Hing if he could use sand from the beach to restore eroded areas. Mr. Manson-Hing said he could not, and told him that sand would have to be obtained from an upland source. Respondent replied that he had an available source of upland sand and would haul it by truck to the beach site. He also mentioned that he would remove an existing pine tree to allow vehicular access. On the next day, December 4, 1984, Mr. Manson-Hing issued an emergency coastal construction permit, #1R-127E, to Respondent. The permit allowed Respondent to place 1,500 cubic yards of sand fill material to restore eroded beach and dune areas at the site, and also permitted him to temporarily place sand-filled bags on filter cloth. In capital letters, the permit warned, "SCRAPING OF THE BEACH IS PROHIBITED." (Dept. Exhibit 4) On December 5, 1984, Lt. Raymond Barker of the Vero Beach Police Department, observed beach scraping activities being conducted on Respondent's coastal property. Respondent was present on the site. Beach sand seaward of the Coastal Construction Control Line for Indian River County had been scraped and deposited at the face of the sand dune. The removal of the sand created depressions in the beach area seaward of the Coastal Construction Control Line. Lt. Barker ordered Respondent to cease the activity until it could be determined he had the required authorization. Respondent complied with Lt. Barker's order. The scraping of the beach and removal of sand below the coastal construction control line was accomplished without a permit from the Department. On July 17, 1985, the Department entered its "Final Order" assessing Respondent a $500 fine for unauthorized coastal construction activities in violation of Section 161.054, Florida Statutes (1985). Respondent requested a hearing; resulting in this proceeding.
Recommendation Based on the foregoing, it is RECOMMENDED: That the Department assess, impose, and collect an administrative fine of $500, to be paid within 30 days of final agency action. DONE AND ORDERED this 20th day of June, 1986, in Tallahassee, Florida. R. L. CALEEN, JR.
