The action to be studied was the possibility ofthe removal or trimming of the mangroves so that motorists could see the water. A second task was the preparation of a permit application should the city decide to proceed with the project. A review of the mangrove trimming regulations and other controlling documents such as the comprehensive plan resulted in the identification of major impediments to the completion (\f the project. Creative designs were developed to nullify the major ecological and sociological obstacles. Regulatory and political decisions and choices remain to be made before the preparation of a permit application. This document reports on the feasibility, recommends an alternative for preparation as a permit application, and maps out the actions needed to procure the permit. As initially conceptualized, the project is not reasonably achievable. The recommended alternative of selectively trimming the mangroves into angled viewing windows~ the revegetation of grassy and open areas to enhance the habitat and augment the window design~ the incorporation of the revegetation into a mitigation plan~ and the development of a site management plan to assure the ecological and sociological maintenance of the product, appears to be attainable. Developing the management plan is expected to cost an additional $8,000. Designing and permitting the appurtenances of the recommended alternative is expected to cost an additional $63,000 but could be spread out over several phases. Total construction costs, also spread out over phases, are expected to approach 1.2 million dollars. Once approval has been granted (anticipated June 1, 1999), an application for trimming the mangroves can be prepared in thirty days (July 1). Approval by the agency may take as long as 4 months (November 1). Bidding the construction may take up to 45 days (circa Jan 1,2000). Construction is expected to take several months and project completion is not expected until mid summer of2000. These estimates represent the minimum expected cost and effort necessary to complete the project. Permitting delays or agency modifications have a greater potential to increase costs rather than to decrease them. 4 File:Deha Seven IDe Memcwy29 I I I I I I I I I I I I I I I I I I I Project Abstract The City of Clearwater desires to improve the vista offered to motorists using Memorial Causeway. The desired improvement is an element of the One City - One Future area wide improvement concept and would serve as an entrance feature enhancement for residents and visitors moving between downtown and Clearwater Beach. The major element of the vista improvement concept is to provide a view of the waters of Clearwater Harbour. This view is currently blocked by mangroves growin~ along the waters edge. The growth is thick in some places and sparse to absent in others. In order to provide a view as described above, the mangroves must be removed or trimmed. The project is to be explored through a feasibility study and the preparation of a permit application package. This report constitutes the feasibility report and a recommended permitting alternative. . 5 File:Deha Seven Ine Memcwy29 u 1 I I I I ~ I I I I I I I I I I I J City of Clearwater Conserva~ Lands i ~ <( ~ .J <( .... ., ( o l: I ~ co ~ . 9 ~ f-..: ~ ~ U , , , , I - \ . ~! ~~ \ " ....

II 1 I I I I I I I I ~ I I I I I I I I I Existing Conditions Current Use The current uses of the causeway are transportation, recreation, and as various utility corridors. Transportation and utilities as uses are obvious and need not be expounded upon. Observed recreational uses are primarily walking.. jogging, and roller-blading along the path provided. Many of the hikers also participate in bird-watching activities. There are occasional sunbathers and people just having lunch or reading. Fishermen were not observed but probably use the area occasionally. Ownership In 1925, submerged state lands were granted to the County of Pin ell as by an act of the legislature. Chapter 11050 Laws of Florida 1 dedicated property to the county for the expressed purpose of building a bridge from the mainland to the islands that would become Clearwater Beach. In addition, other lands were dedicated along the north side of the bridge center line for the specific purpose of public parks and recreational uses. The act contains a reverter clause if these purposes were not respected. The county developed the bridge designs and then transferred the construction contracts to the City of Clearwater by resolution in 1927. It was not until 1941 that the legislature designated Gulf to Bay as a State Road and identified it as SR 60 (Ch 20755 LoF2). Only a portion of the 235 acre (mol) parcel needed to be filled in order to construct the island which would become the causeway. For the purposes of this study, only the area between the eastern and western bridges is considered. This portion of the parcel is 1300 feet wide and approximately 6755 feet in length along the center line. Within these 201.60 acres, only 45.75 acres have been filled to create the island which varies in width from 220 feet to 430 feet. The road bed has been filled to elevations between 6 and 8 feet MSL. The road itself is 60' wide and includes 2 travel lanes and a median. Along the southeastern portion of the island, there is a small parking lot for visitors. Island Way intersects SR 60 and provides access to the residents and businesses in Island Estates. Adjacent Lands The majority of the lands adjacent to the site are submerged lands. Some of these parcels are 1 Appended: AI: Chapter 11050 LoF. 2 Appended: A2: Chapter 20755 LoF. 6 File:Deha Seven Ine Memcwy29 I I I I I I I I I I I I I I I I I I I owned by the State of Florida and others by the City of Clearwater. Private properties are limited to those along Windward Passage, and at the eastern and western bridge footing. A complete list need not be generated until a permit is submitted. A partial list is appended.3 The parcel to the north, and east ofIsland Way is a City owned Perpetual Deep Water Park (OR 259 Page-I 17). 4 Legal Description, Zoning, Land Use There is no parcel identification within the property records of the county and the legal description is only contained in the act (11050 LoF). Generally paraphrased, however, it is described by a series of arcs and lines commencing at a point 601.65 ft west of the intersection of Cleveland St. and Osceola Ave. The described arcs total 8549.09 feet in length and the properii~s~~~ extend 500 feet to the north and 700 feet to the south totaling approximately 235 ar~..e.

The Conservation Lands Map as included in the ConservatIon emen 0 the Plan clearly shows the mangrove fringe of the Causeway to be included as a Conservation Area (Figure 1). Both Land Use and Zoning are regulated by the City Commission under the general municipal zoning code and Comprehensive Plan's Land Use designation. While zoning and land use are primarily controlled by the City of Clearwater but they must be consistent with each other and also consistent with the Pinellas Planning Council Guidelines and criteria. The code limits activities in Recreation! Open Space areas and includes the restriction that "public works projects are to be screened with continuous landscape screen or wall." In this context it is probable that roads in general are not considered to be public works projects and are therefore exempt from the requirement. For parking areas and access points, sight distance must also be maintained. Land Uses as defined by the County Wide Plan Rules generally allow the use of the island as a park and should not create difficulties. The Land Use definition of Scenic/ Non-Commercial Corridor, however, contains the direction to "...preserve and enhance the scenic quality found along these corridors..." This gives ample direction to manage the vista and leaves only the exact 3 Appended: A3: Ownership records. 4 Appended: A4: Perpetual deep water park dedication. 5 Unless noted otherwise, area and length values have been scaled or derived from aerials and do not represent surveyed data. 6 Appended: A5: Recreation!

The Zoning Code7 also promotes the use of the island for recreati however, lies a definition that will affect the course of the proje . addresses preservation lands. While the island is not itself zone portion is so zoned: Division 31 contains the statement that "The tion District shall apply to all surface waters and submerged lands thereunder." The language goes on to say that ''Furthermore, the Preservation District shall be applied to all upland areas 30 feet landward of mean high tide where mangroves exist." The code goes on to require a 25 ft buffer around all preservation lands and jurisdictional wetlands.8 The buffer has a dual definition and the most restrictive must be applied. Where the edge of mangroves lies more than 30 feet landward of the MHT, the edge of jurisdiction would be landward of the preservation zoning district and the buffer would commence landward of the wetland line. The Preservation Use Limitations (Sec 40.585) go on to state that ''No...removal of established native vegetation shall be permitted except as may be specifically authorized by the City Commission, the USA Corps of Engineers, and the State [emphasis added].9 Most salient to the point of this project is the requirement that the removal be specifically authorized by the city commission. A finer point that alteration through trimming is not removal directs the development of the vista improvement project towards hedging and trimming instead of actual mangrove removal. Chapters 163 and 187 of the Florida Statutes require that each community examine its future in a comprehensive and holistic manner. The guidelines to achieve this future is then codified and adopted subject to ratification by the State Department of Community Affairs. All Land Development Codes and activities are required to be in accordance with these guidelines, known as the Goals, Objectives, and Policies of the Plan. Superior plans, such as the Pinellas Planning Council, th~ Regional Planning Council, and the State are relevant, not regulatory, but should still 7 Appended: A5: Recreation!

This is probably an error in semantics unintended by the composers of the plan and is not expected to create problems with the current project. If taken literally, however, it could become problematic in other projects. It is recommended that this language in the plan be changed at the next regular opportunity. 9 File:Deha Sevm IDe Memcwy29 1 I I I I I I I I I I I I I I I I I I be considered. The relevant policies of the adopted Clearwater Plan10 serve to very strongly discourage the pursuit of the vista improvement project. Pursuant to nuances of interpretation, Policies 22.3.1, 22.3.2,22.5.1,22.5.3,22.5.4, and 22.7.1 would seem to make the alteration of these mangroves either very difficult or impossible. This is not to say that the comprehensive plan could not be changed to accommodate the project. Changing the land use designation and modifying the policy statements could, however, be somewhat controversial. Such a change would certainly be costly and time consuming. Site Description The road to Clearwater Beach was constructed as a long narrow island with a bridge at each end allowing for boat passage and tidal circulation (Figure 2). The road lies generally in the center and is 4 lanes with a landscaped median. To either side of the road there are open grassy areas sloping gently to the edge ofthe wetlands. Within this area, which is broader to the south than to the north, there are occasional palms, oaks, and sea grape trees. A combination bicycle path and walking trail runs through the grassed areas on both the north and south sides of the island but the two do not connect at the ends. The small parking lot mentioned earlier can accommodate approximately 8 cars and is landscaped with Oleander. Nearly all of the landscape material is composed of exotic plants the only exception being the oaks, sea grape and the occasional cabbage palm. The grasses themselves are a mixture of lawn grasses and the native Distichlis spicata in wetter areas or areas subjected to frequent salt spray. Other exotic plants noted were the infrequently occurring Brazilian Pepper and Air Potato. The shore is generally stabilized with concrete rubble and rock, much of which is hidden from view by low creeping grasses or by the mangroves. The rubble is more extensive along the southern shore. Black, Red, and White Mangroves occur in varying conditions along the shore (6.96 acres). In general, the largest stand of mangroves occurs in the northeastern quadrant while the southeastern and southwestern shores are nearly devoid of all vegetation. In the large stand, the depth of the mangroves reaches 100'. In many places along the southern shore, they occur as single small trees. The height of these mangroves was surveyed by City Staff in 1994. At the time, the maximum height was 26' above Mean Sea level (MSL), the average being closer to 20' tall. Since mangroves typically grow just above Mean Sea Level (MSL) they can be presumed to have been slightly less than 20' tall at the time. Since then, growth has likely elevated the canopy above these figures. Local observers relate that the mangroves along this island were severely frozen in the middle years ofthe nineteen-eighty's. While these observations are valuable, they are 10 Appended: A6: Excerpts & Analysis of Comprehensive Plans. 10 File:Delta Seven Ine Memcwy29 I a .

The tall mangroves along the northern shore would not have achieved the heights recorded above in the post freeze years. The mangroves along the south shore, however, show direct evidence of old freeze damage and the local observations may be more reliable. Freezing weather is the range limiting factor for our mangroves and the Anclote River is generally considered the northern range limit for most of these trees. It must be noted that range limitations are a broad line, not an exact one. Periodic freezes will keep mangrove forests in the Clearwater area from achieving the non-perturbed climax status common in southern regions while not eliminating them. Other perturbations or disturbances to the ecology include noise, lights, and other human behaviours. Wildlife observed on site fall generally into upland and wetland utilizing species. Upland fauna were generally limited to birds including Fish Crows, Mockingbirds, Red-Winged Blackbirds, and the exotic escapee, the black hooded parrot. Wetland utilizing species included Yellow Crowned Night Heron, Snowy Egret, Fiddler Crab, and the Mangrove Water Snake. a e Xlstmg lte ea ata.

S' Ar D Alternative Development Introduction The traditional approach to alternative development was quickly determined to be inappropriate due to the unusual circumstances surrounding the project. The Do Nothing alternative simply does not satisfY the goals of the city management team. Conversely, the hedging of all the mangroves along the island would have required a change to the Land use Plan and off site 13 File:Deha Sevmlnc Memcwy29 I I I I I I I I I I I I I I I I I I I mitigation, either of which would have made the project extremely costly and not feasible.11 The development of alternatives was further complicated by a wide variety of legal and political constraints. Alternative development was modified to be a process of hierarchically resolving individual components of the developing alternative until a point was reached where the project could be deemed achievable. Using this procedure, the alternative recommended has minimum criteria as fixed components and retains flexibility in how some of these may be applied in the final product. The sequence of problem resolution is presented in the following sections. Trimming Style Historically the trimming of mangroves has been limited to two basic styles: Hedging and Lateral Trimming. In the first, the mangroves are topped and reduced to the desired height creating a flat topped appearance as in a garden hedge. In lateral trimming the main trunk is left intact and the lateral branches are removed. The canopy is preserved in this method and a view is allowed through the remaining trunks much as in a park. These have been applied in two styles as well. In one style the entire waterfront is trimmed using one method or the other. Alternatively, only a section of the shore may be trimmed creating a window effect. Occasionally, these methods may be combined resulting in a waterfront where a section has had the tallest trees trimmed laterally and the shorter ones hedged creating a vertical and horizontal window effect (photographs 2 through 5, pages 15,16). Consideration was given to hedging all the mangroves to a height which would allow the motorists to view the bay over the tops of these trees. The height to which the mangroves would need to be trimmed (less than 2 feet in places) was such that there would be little functional difference between the hedging and total removal. Lateral trimming may give the motorist a strobe like effect due to the depth of the mangrove stands and the need to retain a significant number of upright trunks. The creation of these types of windows did not meet the general project requirements of offering a continuous vista of the bay. Analysis of Potential Vista Alterations Any evaluation of vista improvement must include the questions of what is to be viewed and from where it is to be viewed. The analysis must also ask the question of whether the view obtained is aesthetically pleasing or if it is better left obstructed. The stated intent of the project was broadly focused to generally improve the vista but details tended to direct attention towards the 11 Modification of the Clearwater Comprehensive Plan to rectify the policy limitations was anticipated to be $5100 plus staff time to prepare and manage the change. Should there be opposition to the change the cost could easily go as high or higher than $41,000 plus staff time. Should off site mitigation have been chosen, the costs are expected to have been near $700,000 plus the cost of property. 14 File:Deha Seven Ine Memcwy29 I , , , , " , J - , , , , . , , , , , Photograph #2: Hedging- Note vehicle behind hed~e, ,,' ""I Photograph #3: Comhinatiorr of styles 15 File:Delta Seven Ino Memcwy;29 I I . , I , I , . . . i' . . . . . . , Photograph #4, Combination of styles Photograr>h #5: Combination of styles 16 File:Delta Seven Ine Memcwy29 I I I I I I I 'I I I I I I I' I I I I I enhancement of the vista of the motorist approaching Clearwater Beach from the downtown area. The first analysis then is with respect to the view of the driver traveling westerly along SR 60. Please refer to Figure 3 throughout the next few paragraphs. This driver is operating a motor vehicle traveling at speeds of up to 60 MPH and as slow as 35 MPH (Personal Observation). The existing view to the north is of a wall of mangroves until the motorist passes Island Way. After this point, the driver is able to see the Marine Science Center and the boats in the adjacent marina just over the tops of the mangroves. If growth continues, this view will be eliminated within a few years. Just before the bend in the road, the view opens and the driver is presented with a water view of the businesses and hotels along East Shore Drive. The view to the south by this same driver is very different. The driver is presented almost immediately with an extensive view of the waters of Clearwater Harbour that extends for several miles to the south. The vista is short lived, however, and once past the parking lot, the view is obstructed by thin, but tall mangroves. This wall, acting synergistically with the northern obstruction has been described as creating a tunnel effect that lasts until the driver is several hundred feet past Island Way when the mangroves thin and the driver is presented with a view of seawalled residential finger canals. It is very likely that it is the disparity between the open water view presented initially and the combination of the tunnel effect and the view of the developed waterfront that has led to the initiation of the project. To improve this vista, the first instinct is to remove or hedge all the mangroves. It is at this point that the other questions must be reviewed. Were all the mangroves to be removed, the same driver would be presented with open water views to the north and south. Only a third of the way along the road, the northern view would be replaced with a vista of seawalled residential canals, the entrance to Island Estates, The Marine Science Center and the previously mentioned waterfront along East Shore Drive. To the south, the expansive water view would not be eliminated until nearly halfway across. The developed shoreline to the south is more distant than that to the north and the vista retains some aesthetically pleasing attributes even when closely approaching the western bridge. The results of these analyses are that the driver would prefer an extended southern view over other options, The second analysis is to examine the vista presented to the driver leaving Clearwater Beach and returning to the mainland. This driver is presented with a northern view similar to that of the westbound driver. The southern vista is different in that the easterly traveling driver is first presented with a view of Clearwater Harbour to the south. This vista lasts until the driver reaches Island Way and the view is blocked by the mangroves. The vista recurs once the parking lot is passed, but is now a view of the shoreline adjacent to Pierce St. The Harbour is still visible only if the driver turns his head almost ninety degrees to the right. Were the mangroves to be removed, this same eastbound driver would have an extensive and persistent view of the waters of Clearwater Harbour to the south. Of particular note, however is the fact that this driver would also be presented with an extensive view to the north once Island Way is passed. Just as importantly as the view of the driver is the analysis of the vista in the obverse. Were all the mangroves to be removed, what would the change in vista be to those residents of Island Estates; the residents along Pierce St; and to those in the Devon, Brightwater, Bayside, Bayway area. What affect would the change in the vista have for those recreational users of the Harbour? 17 File:Deha Seven !ne Memcwy29 I , . . , . . . . . . . . 11 . . . 11 . ~\~ . 1\ \; "1\ :'. 10 \ i' \ ) '.<<J Q \ ~ . 0 I , I" " ,~ l~< )fI 11111 ~~l..""!!ii...~. t )J/j ~i\~ '~~ ~~ 1......,.! \ / " \ ~ ...., , ] l,i ] /~ Ii!" ~ ~ " {'ii ~ ~;\ 1..Jit: ~.~f ~!l J~~ 1~---;:::/, ,; ~ r~1Jl. : -~~- I G l ~ i ~ ~:I .\ it- : l\'~ '~'\ ~":', \~>~._,;-, ~ ~ 0, ~ 'i) ~ 1=1 ~ ~ "0 .~ P< 'Oi' .E 6 b {j 'S ~ "" ~ g !:1 '" B 'g' <lJ 8 6 ,g ~ -0 .B ;J ~ I CJj " :> (:, 1? ~ ~ ~ <lJ '" CJj 0 @ :; U ;9 ~ J ~ ~ ~ .~ .S 'tl .~ ~ ;e '" II: t t;j ~ t i1 '" D~ '€ ~ o ~ ~ f' ~ ~ til ~ il 8' ) oll " '0 II: ~ o ~ o ~ 'i) .~ o <Zl ~ ~ 0; .~ "0 ~ s o -e '" II: t t;j ~ D ~ <Zl 'i) ~ t;j ~ il 8' ,!:I ::l o ~ II: t til ~ ~ D ~ <Zl 'i) ~ til ~ il ....! ~ "0 .~ P< I I I I I I I I I I I I I I I I I I I Would they prefer a vista of a tree lined island or of a denuded causeway and traffic? Property maps were examined and it is apparent that the vista for numerous areas may be subject to change as a result of this project. They include, but are not limited to properties along Bayway Blvd, Pierce St., Drew, Bayside, Brightwater, Hamden, North Osceola, East Shore Dr., Windward Passage, Leeward Island, Midway Island, and Windward Island. The proposed alternative must take these interests into account. Residential property owners in these areas fall generally into two categories. The first includes those owners who reside in multiple story buildings. For these people, the alteration of the mangrove fringes will not affect their view one way or the other. The one exception occurs where the multiple story facility has ground floor recreational facilities that are frequented by residents. As these areas are equivalent to the backyards of single family home owners, they must also be respected. The second category, the single family home owner, has experienced a view of a tree lined island for several years and is likely to have become accustomed to such a vista. Those in the Island Estates subdivision are the closest and most easily affected. Those along the western and eastern shores of Clearwater Harbour typically have alternate views either up or down the bay. Residents of the southern ends of the Island Estates finger fills have the causeway as a major component of their vista. When comparing the two views of the motorist and the homeowner note that the resident is stationary having the same view all the time. The motorist is moving and the pure expanse of view must be larger to accommodate the multiple points of origin of his view. While this may seem to elevate the motorist over the resident, it actually has the opposite effect. The view of the resident can be protected more easily as the motorist has other options. Finally an analysis of how short the mangroves must be cut is needed. The driver is seated in an automobile atop a road which is at elevation 8 and that driver wishes to see the water over the tops of mangrove hedges that are as much as 200 feet away. Vistas tend to feel constrained if peripheral vision impaired whether that be in the vertical or horizontal plane. An angle of three degrees was used to being the analysis and cross sections were prepared (Figure 4). Based on a few typical sections, the hedged mangroves could be extremely short. The impact of this may be to reduce the angle of declination providing a more distant vista than originally desired. An absolute lower limit of 2 feet should be used to avoid killing the mangroves altogether. U sing the view analysis as a point of beginning, the recommended alternative was deduced systematically by applying the criteria established in the feasibility factor analysis. Of primary consideration was the achievement of the desired vista while reducing or eliminating opposing factors. The recommended alternative must balance the vista improvements against the vista degradations: maximizing the vistas of open waters while minimizing losses to residential areas and recreational users. The most desirable vista for the island user is that of open waters or of local attractions. The Marine Science Center is the primary attraction considered in the development of the view patterns. Undesirable vistas include heavily developed seawalled residential areas. It is fortunate that these same areas are anticipated to be the source of most of the local opposition. By eliminating the vista of these residential areas for the motorist, the obverse vista of the tree lined 19 File:Delta Seven Ine Memcwy29 I I I I I I I I I I I I I I I I I I I ...... ~ llJ 'S .. 0.. ...... i 5 ~ 8=- o = ~';jO o 0 (;fl 1-0 llJ llJ 0..

Public Safety Several reports were made that the island was a haven for a criminal element and that removing the mangroves would eliminate places for these people to hide. In fact, the record of arrests does not support these statements. There is, however, ample evidence that the mangroves are commonly used by people camping or otherwise residing in the woods on a regular basis. It is beyond the scope of this project to eliminate unfounded fears of criminals in the shrubbery. Another concern under this category is related to traffic safety. The posted speed ofSR 60 is 45. mph. Once a vista of open waters has been provided it can be expected that daily users of the causeway will become inured to the view and travel at or above the posted speed as is common now. Tourists and occasional visitors may have a tendency to slow down and enjoy the view. The larger the differences in speed between the fastest and slowest vehicles on any roadway, the greater the chances for accidents becomes (traffic friction). Traffic safety considerations focused on attempting to maintain traffic flow continuity. Analysis of driving patterns leads to the deduction that the most desirable vista is out the front window. The center of that view will be the roadway leaving only the left or right oblique for view presentation. Considering the need to have drivers eyes aware of oncoming and turning traffic, the view out the left oblique is most desirable. Under these constraints the driver is not only presented with the vista of the bay but the driver's gaze is directed across the traffic lanes. The desire to focus the drivers eyes across the roadway leads to the development of viewing windows aligned on an angle oblique to the roadway versus the more commonly seen perpendicular arrangement. The benefits of this alignment are immediately apparent to the resolution of the view problems. Arranging the viewing windows on an angle creates an effect similar to that of vertical blinds on the window. A person aligning themselves with the angle of the slat of the blind has a nearly unobstructed view while a person looking in on a perpendicular angle wi~ not see anything but the slats. Noise The county expressed a concern that the existing mangroves may provide a significant noise barrier. Such an attenuation zone was thought to buffer the waterway users and nearby residents from road noise. Noise readings were taken on a week day over a four hour period both at the edge of the roadway and at the roadside edge of mangroves various distances from the road. The result of this study12 was that road noise is naturally and significantly attenuated. In most cases the noise recorded had reached background levels prior to reaching the waters edge. In many cases, the noise was attenuated before reaching the upland fringe of the mangroves to the south. Recommendations from this study are to improve the overall sound profiles of the island through vegetation management. The angled or slatted viewing window alignment when conducted through hedging alone results 12 Appended: A7: Noise Report. 21 File:DeIta Seven IDe Memavy29 I I I I I I I I I I I I I I I I I I I in remaining mangrove stands of unequal width because the depth of the original fringe is not consistent throughout the island. The noise concern, in combination with thin spots in blocking the obverse view, leads to the extension of the mangrove slats by the addition of plant material on either the wetland or upland edge. A secondary benefit of these plantings is that the noise which currently inhibits the faunal use of the mangrove habitat can be attenuated prior to reaching that area and the total habitat function is enhanced. This vegetative attenuation may be significant but is variable pursuant to vegetation type. Newly planted upland buffering material will be selected to alter the sound profiles such that the mangrove habitat is not acting as the noise buffer but is instead the recipient of improved upland attenuation properties. Because noise increases are not a major im;!l.ct ofthe trimming, the sound attenuation may easily be offered as a mitigative measure. By planting upland and wetland plants, not only can the noise profile of the habitat be improved, but the vista management and safety concerns can be eased. Lights The county expressed a strong concern that residents of such nearby developments as Island Estates may enjoy the vista of the mangroves and not appreciate the new vista of oncoming automobile headlights. Although not based on concerns expressed from citizens to the county~ it is a valid factor. Lights were considered to be a factor by county staff early in the process. Since view management and noise were already leading to the development of angled windows, the headlight issue is easily resolved by affirming the infill planting noted in the noise solution. The plant materials to accomplish this effect must be leafy and thickly growing. Interproject Coordination Public Recreation Public recreation as a factor has its foundation in the original legislative act. The recreational uses most commonly observed include birding and the use of the walking path. The recommended alternative must take these factors into account. Adding new recreational opportunities was heavily considered in the development of the recommended alternative. The location of planting new vegetation must also consider the current and anticipated uses of the island. Given the observation that the walking path circles the interior and that little activity occurs waterward of this path, those waterward areas were targeted for heavy revegetation. Bridge The City and the FDOT are currently engaged in replacing the eastern bridge to the island with an elevated fixed span structure. The approach will be realigned slightly to the south. In order to fully assess the needs for mangrove alteration., profiles of the new road bed were attained. The new road bed will be elevated significantly and won't rematch grade until west of the existing parking lot. The effect of this new bridge on the mangrove alteration is that the easternmost mangroves will need less alteration because the line of sight is higher than under existing 22 FiJe:DeIla Seven IDe Memcwy29 I I I I I II II I I I I I I I I I I I I conditions. The new bridge to the east and the elevation of the roadbed eliminates the need to trim the mangroves in the most viable stand; the northeast quadrant. Drivers coming over the bridge will have a totally unblocked view of the open waters to the left, across travel lanes. The second affect is due to the realignment (Figure 5). The new approach will traverse a currently sparsely vegetated area of the island and open up the old roadbed for potential mitigative opportunities. Western Gateway Improvements The City is preparing plans to improve the western bridge and the approach to Clearwater Beach. The recommended vista improvement alternative should enhance the new entrance features of Clearwater Beach at most, and not be contrary to them at worst. A transition zone from a more natural to a more urban landscape has been incorporated into the alternative. SWIM & The Aquatic Preserve The City has nominated Clearwater Harbour for status as a SWIM water body under the Surface Water Improvement and Management Act. Sovereign State Lands in the vicinity are part of the Pinellas County Aquatic Preserve and subjected to high standards of preservation. Each of these classifications require the development of a management plan. The status of the City's Perpetual Underwater Park is not known. Should the Island also have a management plan, it would be nested within these two plans, neither of which has been written. Each of them, however, would place a great deal of emphasis on the preservation and enhancement of local habitats adjacent to their waters. Should the SWIM nomination be successful, the submerged portion of the parcel would be subject to the SWIM plan for Clearwater Harbour. The Aquatic Preserve plan would not directly cover the island or the submerged lands, but is relevant for purposes of continuity in planning. All of these plans include water quality and habitat quality as major goals. They also recognize the need to appreciate and use these resources. Mangrove alteration, therefore is not in direct conflict with the general intents of these planning guides, but total removal would be. The inclusion of recreational opportunities and educational programs is directly supportive. A management plan developed for the island which includes these elements should gain mitigative credits. Net Environmental Benefit The county has repeatedly expressed its fundamental criteria that the project must provide a net environmental benefit. Addressing this criteria within the permit application is mandatory. Having defined the operational and functional components of the trimming plan and vista improvement, the plan must be evaluated against the test of whether it provides a net environmental benefit in accordance with the county criteria, the public interest test, and the cumulative impact criteria. In order to provide a proper baseline for impact and mitigation analysis, an ecosystem characterization is necessary. From this, weights can be assigned to various elements of the local ecology and decisions on what is an appropriate loss and an appropriate compensation can be made. 23 File:DeIta Seven IDe Mcmcwy29 I I I I I I I, I I I I I I I I I I I I ""0 ro o "cG ~ '~ ~ .- tj ~ ---', Q) Ir~\Z n\;'\~ :,.'

I ) \ < ( ;' \ , 1.-1 I I I I I I I I I I I I I I I I I I I Existing Ecological Conditions The existing ecology of the island can be generally expressed as poor. While there are significant acres of mangroves, the value of mangroves is not simply the value of the trees themselves. There is significant additional value in the fauna and flora utilizing the habitat created by the tree. This point is even more salient where mangrove trees occur singly rather than in stands or forests. The lack of depth in the mangrove fringe itself is limiting in overall habitat structure. Inhabitants within the mangroves included several birds common to the area: Yellow Crowned Night Heron, Snowy Egret. None, however, were noted to be nesting and no evidence of previous nesting attempts were observed. Unoccupied small b. - 2 r.ests were noted and were most likely mockingbird nests. The edges of the mangroves were inhabited by Fiddler Crabs, and the Mangrove Water Snake but again, the paucity of fauna was notable. Raccoon tracks were not noted during any observation periods. Mangrove associated gastropods were not noted. The uplands associated with the mangroves are ecologically nearly barren. The frequent mowing, the predominance of exotic turf and shrub species, the lack of fresh water, shelter, upland trees or shrubs are extremely limiting to the development of significant urban wildlife populations. The constant noise of the roadway certainly does nothing to enhance the value of this area. As noted previously, the cycle of freezing, while lengthy in periodicity, has certainly played a role in inhibiting the development of a broader fringe of mangroves. The above notations should not be considered to be an opinion that the mangroves have no value. They still contribute leaflitter to the marine system, stabilize the soils and most importantly, buffer the nearby shallows from the impacts from which they themselves suffer. The shallows, particularly those near where the mangroves are thickest were often used by wading birds in their pursuit of small fish and crabs. The freeze cycle also should not be looked at as a reduction in value. Range termini often produce stunted or intermittent growth patterns and the local fauna have adjusted and evolved to use that habitat in the same manner as fauna associated with mature forests have done. Turtles Marine turtles' have rarely been reported nesting on beaches interior to the barrier island system and nesting on the causeway in areas where mangroves do not occur was raised as a possibility. There is no direct evidence at this-time that any turtles nest on the beaches of the causeway. The Clearwater Marine Science Center has no records of nests or false crawls. The rubble along the waters edge may also affect the ability of turtles to use the site, but the lack of false crawls indicates that it is not a significant factor. Proposed Ecoloxical Conditions Vegetation management is the primary activity and the one which will provide the vista desired. The design protocol is to hedge those mangroves in designated sight windows and then to plant new native vegetation, either in a low grrmring form or in tree form, to complete the window effect. The entire area waterward of the existing bicycle path will be converted from exotic turf grass to native vegetation. Bearing in mind the observations that trees, shrubs, and grasses by themselves fulfill only a portion of the habitat requirements of most wildlife, it was noted that adding a source of fresh water to the island would enhance the habitat suitability greatly. 25 File:DeIt.a Seven Ine Mancwy29 I I I I I I I I I I I I I I I I I I I The result of the vegetative management plan is presented in table two. While the total mangrove replacement is not equal to the mangroves trimmed, other compensatory factors should be considered by the county. The test of net environmental benefit lies in the consideration that the native habitat area would increase from 6.96 acres to 15.92 acres. The added benefits offresh water and noise abatement will significantly add to the ecological value of this island and county biologists will recognize that fact. The question of the sufficiency of such compensation must await a permit review. 26 File:Deha Seven Ine Mcmcwy29 I I I I I I I I I I I I I I I I I I I Table Two: Recommended alternative site data.

The proposed vegetative management plan does impact the local ecology by removing the canopy from 2.35 acres of mangroves. The impact area has been carefully chosen to confine the hedging to those acres in a somewhat less than pristine condition and to preserve the best mangroves on the site. The addition of fresh water, marine coastal grass habitat, upland forestation, and coastal scrub will augment the mangroves considerably. The increase in total mangrove acres and the creation of these native habitats now extant from the island will improve habitat diversity, the overall function and capacity of the ecology, and the recreational advantages to those engaged in observing nature. With respect to the plan as developed to this point, it should be noted that in general habitats that have several components are more valuable than single component systems. The existing mangrove strand combined with mowed grasses is not supporting viable populations of urban fauna. The proposed habitat clearly represents a net ecological benefit. Legal Factors Federal The US Army Corps of Engineers was contacted regarding the concept. The USACOE does not regulate the trimming of mangroves in any manner. It is imperative, however to note that should the trimming result directly or indirectly in the death of any mangrove or wetland species, or in the erosion of a shoreline previously stabilized by the mangroves, the USACOE would consider the activity to be mangrove removal without a permit or an activity leading to the filling of wetlands without a permit and either would be considered a violation of the federal regulations protecting wetlands. State Mangrove removal and alteration is regulated under Chapter 403.9321 of the Laws of Florida. The act itself sets forth exemptions, criteria for more general permits and a requirement that all other activities will need a specific permit. The latter has little approval criteria associated with it other than the. need to consider net environmental benefit, public interest, and cumulative impacts. Provisions to accept mitigation for otherwise unpermittable activities are .included. It is inescapable that one of the primary goals of this act was to preserve forever the vast majority of all mangroves in public ownership. "It is the intent of the Legislature that no trimming or alteration of mangroves may be permitted on uninhabited islands which are publicly owned or on lands set aside for conservation and preservation, or mitigation, except where necessary to protect the public health, safety, and welfare, or to enhance public use of, or access to, conservation areas in accordance with approved management plans.

These views may be of minimal adverse impact due to the narrowness of the obverse window and the distances involved. The remaining low vegetation will also block the headlights. The few homes which are affected are more than 900 feet from the road. The water way user's view of the island will also change. Due to the mobile nature of such a user, it is not possible to quantify the change in view. It is possible to determine that qualitatively, the view will generally include more tree lined shores and fewer vistas of rubble and traffic, especially from the main navigational channels. The proposal therefor increases the quantity of the motorists' vista by approximately 79"10 while only minimally impairing the view from a very few backyards of adjacent residents. Current Sitm~tion In conclusion, Delta Seven has defined a feasible alternative which will achieve the general goal of the project: To provide a vista of the waters of Clearwater Harbour to the motorists using the Memorial Causeway Scenic Corridor. In order to achieve this, a decision must be made to pursue the recommended alternative. A management plan must be prepared and approved prior to the submittal of the application. Appropriate budgetary modifications must accommodate this latter choice. The management plan could be prepared and submitted with the application on July 1 st. The municipal mechanisms of approving the management plan have yet to be undetermined. Statement of Feasibility The recommended alternative is considered to be realistically permittable and achievable. The alternative clearly provides for a net environmental benefit~ meets the public interest test; meets the cumulative impact test; is not contrary to the existing comprehensive plan; and is not contrary to the intent to preserve mangroves. The latter two statements can be made because the resulting mangroves will be more extensive and augmented with upland habitat. In the worst case, the amount of mangroves planted may be required to be increased from 1.04 acres to 2.35 acres in order to provide for a one to one replacement of hedged mangroves. Should this occur, several options are available including the narrowing of windows~ the elimination of less critical windows; the reduction in trimming; excavation to wetland elevations; or a combination of the previous. 38 File:Deha Seven Ine Memcwy29 I I I I I I I I I I I I I I I I I I I viable approach lies within the exceptions to the prohibition contained in the final phrases.17 The statute provides for an exception to the prohibitions where an approved management plan exists. There is some uncertainty in the interpretation of the statute as to the exact meaning of the term "approved management plan." The county was willing to accept a plan that had been formally adopted by the City Commission provided that it met the tests of consistency with the comprehensive plans. In the absence of any approval of other alternatives the development and enactment of a management plan for the island could result in a viable assurance of net environmental benefit as well as allow for a technically acceptable pathway to approval. The formal adoption of the management plan would also serve to resolve the comprehensive plan issues as both would have been adopted by the same body of elected officials: The specific plan could take administrative precedence over the general policy statements as long as it was not contrary to those statements and furthered the overall goals of the City. Capturing the vegetation plan within a management plan will enhance the probability for success. County Pursuant to Chapter 403.9324, Pinellas County has accepted a delegation from the State of Florida. All trimming and alteration activities not associated with other state wetland permits are being.processed and enforced by the county's Department of Environmental Management. While the regulations make reference to Chapter 120 Florida Statutes as a means of relief, neither the state nor the county is required to publish a notice of intent to issue permits under the act and permits are normally issued administratively. Each of these agencies, however, reserves the right to advertise a pending permit and hold hearings should they determine that the public may be better served in this manner. The county further reserves the right to waive administrative approval and schedule the application for a decision by the Board of County Commissioners. In either situation, an aggrieved party may file an appeal under the provisions of Chapter 120 Florida Statutes. Conversely, neither the state nor the county are subjected to the sections of Chapter 120 which are designed to assure applicants of an expeditious review and approval. The section commonly referred to as the 30 day clock does not apply. Under normal circumstances the county performs at a level which meets this clock and it is not expected to present an impediment to obtaining the permit. The question of whether the delegation also entrained the ability to enforce the habitat protection codes of Pine lIas County's Land Development Code has been resolved in a manner that eliminates such an extension of the regulations. 18 The statute clearly provides applicants the opportunity to mitigate for impacts of mangrove alteration where a permit cannot otherwise be issued. In the current situation, the options to mitigate may be either on the island itself or in a nearby coastal area. It is also within reason to 17 See the End Notes for more in depth discussions. 18 Appended: A8: Pinellas County letter dated Sep 18, 1998. 29 File:Deha Sevcnlnc Manl.wy29 I I I I I I I I I I I I I I I I I I I develop mitigation plans that are not a strict one for one or type for type replacement of altered systems. In urban settings it is often more desirable to provide for complete ecosystems rather than to simply replace the wetland fragment. It is common for the ratio of mitigative replacements to be higher than one for one.19 In consideration of the statutory issues, the alternative must include mitigation. Mitigation being a certainty, a location on site was determined to be highly desirable over an off site one. As the determination had already been made that some vistas were desirable and others were not, rearranging the mangrove pattern became contributory to both vista and mitigation planning. By planting mangroves to block less than desirable views, on site mitigation could improve the overall setting. The use of angled windows reduces the amount of initial trimming needed thereby reducing the amount of mitigation required. The extension of the remaining vegetation into longer slats will generate some mitigative credits. Establishing angled windows in currently non-vegetated areas completes the vegetative mitigation plan. The need to adopt a management plan benefits the feasibility in two ways. The first is to bring the city into a position where a statutory exemption will apply and the permit can be issued. The second is that by enacting a management plan with public educational and recreational components, the resulting island ecology will better fit with the SWIM and Aquatic Preserves Management plans and these aspects will generate mitigative credits and help to satisfy the public interest and cumulative impact criteria. Proprietary During the investigative phase of this project, the parcel origin and history was discovered and has been documented as above. This investigation was needed in order to determine whether the mangroves to be trimmed were within the Pinellas County Aquatic Preserve or whether they were in fact owned by the City of Clearwater. The records reviewed included a letter dated July 11, 1983 from the FDOT and signed by Mr. Montes De Oca20. This letter indicates that a ROW was never dedicated to the FDOT. A further review led to documentation of the land transfers from the State to the County and the County to the City. Municipal Resolutions 57-46 and 60-16 indicate that the City is maintaining the property. There remains to be discovered any documentation of any ROW dedication to the FDOT. The lack of such a document raises questions of what effect Chapter 20755 LoF has on the underlying property. This act does not dedicate ROW or easement, but simply claims Gulf to Bay as a State Road. The Property Appraiser does not list the parcel but does map it with the 19 Appended: A6: Ratios suggested by the Tampa Bay Regional Planning Council.

Political Factors Intergovernmental Relations Pinellas County has a long standing policy of maintaining a certain distance from municipal politics where permits are concerned. In enacting that policy, the county insists that an appropriate level of public and political support for a project is generated prior to issuance of county permits. Similarly, should there be suL ~antive opposition to a permit application, the county will implement their policy by remanding the issue to the City Commission for resolution prior to scheduling any hearings or issuing any permits. The information at hand indicates that there may be opposition to the project as originally conceptualized by the city, but the level of interest by the citizenry has not been tested. Precedent While the legislative intent22 contains the clearly stated goal of preserving public mangroves within certain land use categories, Pinellas County has issued permits regarding the alteration of mangroves within Preservation areas in the past. Two of these permits are salient. One was issued to the City of St. Petersburg and is known as the Tinney Creek Permit. In this permit, the county allowed the trimming and removal of mangroves in an area designated as preservation on the St. Petersburg Comprehensive Land Use Plan. Mitigation was not required. The county states that the underlying property is in private ownership negating the precedent. The law itself makes no such distinction.23 The second precedent is the allowable alterations to mangroves along Edgewater Drive. This permit was also issued for mangroves in a publicly owned Recreation! Open Space area. The county maintains that this precedent is also invalid as the permit was specifically for newly recruiting mangroves and not existing trees. The Edgewater Drive project contains another important message in that the permit, although issued, was never acted upon. This itself is one of the arguments that the county used to attempt to negate the precedent, despite the fact that the decision alone is what sets the precedent, not the enactment. The reason for the abandonment is that the local residents, upon hearing of the details of the permit, individually and collectively petitioned the City Commission to abandon the project. The process of adoption of the management plan for the Memorial Causeway should be sufficient to avoid a similar situation.

During the past five years, all of these boards have heard various alternatives of the conceptual project with mixed reactions. Any management plan or trimming applicatioasl1ould be reviewed by these boards. Cost of the Project Hedging of the mangroves has been roughly estimatedh}'- VMOUS- contractors at $50,000 to $90,000. Mitigation as proposed is expected to be $298,.000. Should off site mitigation be required costs would increase by a minimumof$35MOO plus land acquisition costs. If the county requires a mitigation ratio of greater than one toone, the cost would increase ratio- metrically. Maintenance costs oftrirnmedma-zroYeSjMY_vary from as little as $18,000 to as much as $90,000 per year.24 Maintenance is required because if the trimmed mangroves grow back to their current condition, new permits would need to be obtained. Maintenance of the mitigation is expected to be $53,000 per year for 5 years. . Construction of the non-vegetative improvements contemplated in the management plan is expected to cost 1.2 million dollars. Maintenance costs of the constructed improvements and educational materials are not estimated but shouldIesult in one full time employee plus the associated overhead. Money currently spent maintainingJhe island should remain, but less mowing will be needed resulting in some savingstnoffset a portion of the anticipated costs. The economic benefit of the project is more difficult to define. There have been numerous statements made during the course of the study that. thejmproved vista would enhance the local economy.

The vista is not, however, available in all directions but is restricted to the view from the front window of the vehicle. Mangroves are retained where the vista is less than optimum. As compensation for the trimming, both upland and wetland planting ~posecL Of the 6.96 acres of mangroves existing, 2.35 are proposed to be hedged and 4.61 to be retained. The western end of the island will be landscaped with native palms to provide an entrance effect to Clearwater Beach. Other low use areas will be planted with native w.Oet....l ve material ranging from low grasses to replacement mangroves and upland trees._ L04 acI:eS-willbe planted with mangroves to directly offset the hedged material and an additional 7.72 acres of both uplands and wetlands will be planted to augment the system. The basics of this alternative are presented in Figure 7. In this manner vegetation will be hedged or augmented in order to create the series of angled sight windows along the north and south borderu>fthe i!;,land _ Amotorist traveling in either direction will be presented with a constant if not continuous or expansiYe view of the open waters of Clearwater Harbour. The less desirable vistas will remain blocked. Vistas for island users engaged in bird watching and related activities will be enhanced. Walking and jogging will still be available. The obverse views from the residentiaLdevelopments will be largely protected and in many areas will be enhanced. The view from the Aquatic Preserve users is altered but the design protects the view in all but those areas directly waterw~ofthe angled windows. In many areas the view will be enhanced offsetting the impacts. The angled nature of the window allows for obverse vista protection and directs the driYers e}'eS across the oncoming traffic. In order to satisfy the legal restraints, the recommended vegetative plan is subordinated to a formally adopted management plan. The plan incorporates a variety of educational and recreational elements. These are nature trails and pavilions~ educational kiosks and displays~ an expanded parking area~ day slips for waterborne. visitors~ fi!;,hing piers~ and a freshwater source for the wildlife. These recreational and educational elements have been designed to achieve a clear net environmental benefit. Incorporatinglhese elements into an actual management plan has not yet been authorized. / The final analysis of the suitability of the recommended alternative is whether it meets the intended project goal of providing an aesthetically pleasing vista to motorists using the Causeway. The best analysis of this is to assess the views gained to views lost ratio. In its current state, the motorist is presented with a front and side window view 48% of the time traveling to or from Clearwater Beach. It is significant that the 52% ofthe ~ when there is no view occurs in the very center of the island: Where the view OI the water would be greatest were it available. In the proposed condition, the motorist traveling to Clearwater Beach is presented with a view for 86% of the time of travel. All but the last portion of this view is to the south over the open waters of the bay. The motorist traveling.fmm.Clearwater..beach to downtown is presented with a water view for 87% ofthe travel time. :-:.1S view is of the south bay waters for the first portion of the trip and then the north bay for the last p&rt. Most of the residential areas will be presented with much the same view or an improved view (Figure 8).

"- FS 403.9323(2) The intent section of the statute is very clear. To fully appreciate the intent, it is imperative to avoid taking excerpts of phrases in isolation and that entire sentences, paragraphs, and sections be read together. The key to understanding 403.9323, lies in first obtaining a.complete_understanding of 403.9322, the legislative findings. 26 Simply stated the mangrove trimming and pres.ervation act is an attempt to strike a balance between the recognized need to preserve the mangroves and the expressed wishes of many waterfront property owners to avoid having mangrove growth along their private shores. In the research that went into the development of this act certain observations were made. These aI:e-reflected in the legislative findings. The findings recognize four items of importance: _ . Mangroves are valuable. . Mangroves along populated shores tend to be in narrow fringes rather than large stands. . 80% of mangroves are subjecL to. pres.ervatioaby means other than legislation specific to mangrove protection; Leaving less than 20% subject to homeowner trimming. 27 . Trimming done properly by professionals ~unlikely to cause unintentional death of trees. Armed with these points, the legjs.latnre is. able ~conclude that if all the mangroves on waterfront lots were to be trimmed, the total loss to the state would be only 20010 at its maximum. The legis.latnrefelt.s.ecure in the knowledge that 26 Appended: All: Tinney Creek permit as a precedent. 27 It is less than 20010 because some mangroves fall into neither category. 39- End Notes 1 I I I I I I I I I I I I I I I I I I 80% of the mangrove forest resources would be preserved in perpetuity and it was therefore not necessary to continue to impose the perceived hardship of restricted trimming on homeowners. It was this logic that allowed the legislature to loosen the regulations on waterfront property owners. In expressing this intent, the legislature is clear. thaLthere is to be no trimming or alteration of mangroves in the areas recognized as the 80% otherwise preserved. But the legislature also makes.recognitioILOfthefacUhat some of the mangroves otherwise preserved by virtue of public ownership would eventually interfere with specific public purposes. During_the development. of lJ..i.J.S.. intent, examples CLL this potential were given: Mangroves growing alongside a public boat ramp can grow in a manner that would restrict or. impair.the llse of the ramp. In these instances the need for the trimming of public mangroves to restore the function of public facilities is obviated. The legislature also states. the intent t.o...nat I>lace- ~ public health, safety, and welfare in jeopardy through this act. The language of the act is strong enough, however, that the removal or alteration of mangroves may not be the first response to situations which threaten this priority. In instances where public safety is impaired, other abatement measures mu.st..he considered. It is this balance of strongly preserving the majority of the mangroves and only loosely restricting the trimming of private mangroves that assures the preservation of the resource while still being responsive to private property preferences. The exceptions to the intent are 1.) where necessary to protect the public health, safety, and welfare. 2.) to enhance public use ot: or access to.. conservation areas in accordance with approved management plans. The only options beyond these two are to seek a variance or to change the designation of the lands to a category other than conservation or preservation. Each of these discussions are presented elsewhere in summary fashion. Public Interest as it relates to man~ove trimmini It is critically important that the Public Interest requirements of Ch 373.414(1) not be confused. This citation is common~J referred to as the public interest test. What is important to recognize is that the public interesr8 and the interest of the publif!9 are not necessarily equivalent. The venues for public participation speak 28 Per statute: A12: Ch 373.414, LoF, The Public Interest Test 29 Per public opinion and consensus 40 End Notes 1 I I I I I I I I I I I I I I I I I I to the latter. The statutory public interest test is clearly laid out in the law and the operative pennitting phrase is contained in Ch 373.4l4(1)(a), specifically "...shall consider and balance..." the criteria as listed. There is significant latitude in this level of direction. It is this test and the cumulative impact analysis that comprise the statutory criteria for permitapproval. Health. Safety & Welfare Considering the guidance phrase excerpted from 403.9323(2) regarding public needs raises the possibility of another exception: "...no trimming or alteration...except...where necessary to...protect the public health, safety, and welfare,... " Public health issues do not seem prevalent. Public safety issues are not supported by police reports. Public Welfare may be identified in terms of the economic well being oflocal businesses. This is an important issue and one raised elsewhere. It remains to be seen if it is possible to show that beach businesses will do better if the mangroves are trimmed. Public opinion may also be pertinent to developing this line of argument. It may be argued that the trimming of small mangroves now could reduce the possibility of future economic hardships brought about after they have grown large enough to obstruct the existing view. The economic impact would still need to be proven. ManaK-ement Plan as it relates to the manwove preservation act Considering the guidance phrase excerpted from 403.9323(2) allows for the creation of a site specific management plan: "...no trimming or alteration...except...where necessary to... enhance public use of, or access to, conservation areas in accordance with approved management plans. " The history of the reference to approved management plans lies primarily but not exclusively with the aquatic preserves regulations which require that all aquatic preserves have management plans. The phrase was written to allow preserve managers to avoid being unrp.ali~tir.al1y bound by a.statute without flexibility. The interpretation of this phrase to include management-plans by other state agencies is a foregone conclusion. The ability to include municipal management plans for municipal lands would revert to the interpretation of the word approved. The question of approval by whom i5- salient to detennining the ability to proceed under this exception. While this cannot be fully determined at this time, it will fall into at least one, if not both, of the following categories: city approval or state approval. The city approval will require a finding of consistencr> with the municipal comprehensive plan, perhaps triggering state involvement, and certainly triggering citizen involvement. The state approval may -11ot be delegated to the county and 30 At a minimum by staff and ratified by the commission. 4-l- End Notes I I I I I I" I I I I I I I I I I I I I would be subject to the same public interest test as is the permit. Pursuant to the possibility that the Causeway may be managed in accordance with an approved management pl~an.cLthat ~ pla.n.may include the alteration of mangroves, the discussion encompassed the possible contents of such a plan. How the plan would be fonnalized-Was....also discussed. The plan should be a part of the permit itself The controlling function is the need for the County to have assurances that the. contract of the permit is adhered to as it was written. An alternative would be to prepare and adopt a pla.'1 as a part of the city comprehensive plan. The direct association with th~ permit, however, is broken and it is probably not an acceptable approach. In considering this, it should be noted that a permit can be modified in.futur~years should that become necessary . Other considerations are how this management plan would nest inside the Clearwater Harbour SWIM Plan or the Aquatic Preserves Management Plan, neither of which have been written Thepennit plan may be for the mangroves or the entire causeway. It is conceivable that it may extend.beyond these boundaries pursuant to mitigative optians..selected. The plan must clearly address the terms and conditions for mangrove management as itemized in the legislation to assur~ compliance with the overall intent as well as the permit specifics. It may address both access to and through the mangroves. Statements of justification and rationale must be presented and supported. Extensions of such a plan may include issues related to Edgewater Drive or similar projects, spoil islands, stormwater issues,. marina issues, upland buffers adjacent to mangroves retained, trash pickup, environmental education, fisheries management, on site or off site exotic species..comrols, an.cLother. options which will define the project clearly as one which carries with it a measurable.net ecological benefit. Extensions may be offered as mitigative mPJisure.s...... Should a plan be presented it is critical that the mitigation and the proposed impacts be well documented, detailed, and justified. Variances "403.9333 Variance relief--Upon application, the department or delegated local government may grant a variance from the provisions ofss. 403.9321-403.9333 if compliance therewith would impose a unique and unnecessary hardship on the owner or any other person in control of the affected property. Relief may be granted upon demonstration that such hardship is not self-imposed and that the grant of the variance will be consistent with the general intent and purpose of ss. 403.9321-403.9333. The department..or delegated 10caLgovernment may grant variances as it deems appropriate." In order to meet the variance,.. the_City would neW to prove a unique and 42 End Notes I I I I I I" I I I I I I I I' I I I I I unnecessary hardship. This possibly may be done on the basis of economic impacts to businesses but would need to be strongly supported. The point that the hardship was not self imposed was granted by the county during pre-application discussions. The final point of the variance SectiOIl refer5- back to the intent section. While this is limiting, again, it leaves room to rearrange the mangroves along the causeway thereby meeting the intent but would not allow the total removal or full scale trimming or hedging. Mitiaation "403.9328(2)(a): "If the applicant is unable to meet these criteria, the department and the "applicant shall first consider measures to reduce or eliminate the unpermittable impacts. If unpermittable impact~ still remain, the applicant may propose, and the department shall consider, measures to mitigate the otherwise unpermittable impacts." "403.9332 Mitigation and enforcemenL-.-{l) ~ Ifmangroves are to be trimmed or altered under a permit issued under s. 403.9328, the department or delegated local government may require mitigatiOIL The department or delegated local government shall establish reasonable mitigation requirements that must include, as an option, the use of mitigation b~created undeLs...J73.4135. where appropriate. The department's mitigation requirements must ensure that payments received as mitigation are sufficientto off~t impaC!.S-and are used for mangrove creation, preservation, protection, or enhancement." It should be noted that minimi7.atioIlistheJirststetl-and mitigation the second step. There is no requirement to accept mitigation and no ratio stated. The inference is that the city may be able to meet the.intentJ.hrough the.Jollowing argument. If the mangroves are to be trimmed or removed from the 80% targeted to be preserved and an equivalent or grea.ter amount is replaced through mitigation then the post project total acreage of preserved resources is equivalent or greater to that being preserved prior to the pr.aj.ecL Upanthis basis it is arguable that the intent of protecting at least 80010 of the resource existing at the time of passage of the act would be preserved. Of note when considering this possibility is. that. the cited section .regarding mitigation is designed to offset the inability to meet the public interest test and the cumulative impacts test. Mitigation may occur on site or off site. On site mitigation could occur under the variance_procedure allowing the intent to be upheld while allowing trimming to occur. Under this option some areas would 4-J End Notes ;1 I I I I I I I I I I I I I I I I I I be trimmed and others would be thickened. Mitigation may be possible in the area east of the footprint of the bridge landing where cars will not require a view. Mitigation may also be possible off site on spoil islands or other public properties. Mitigation details must be contained in the permit and in the management plan. In any mitigation or permit without mitigatio~ the application must demonstrate a net environmental benefit. 44 End Notes I I I I I I.

PRESERVATION (P)* *Cross reference(s)--Vegetativebuffer adjacent to aquatic lands/coastal district, ~ 42.28. Sec. 40.581. General description. This district is created to protect the water8,..- waterways and coastal wetlands of the Gulf of Mexico and Tampa Bay and non coastal wetlands, environmentally sensitive palustrine, lacustrine and riverine areas, natural and artificially made interior bodies of water and other submerged lands through the control of development of these areas so that their-ecological and aesthetic values may be preserved for the health and enjoyment of present and future generations. Sec. 40.582. Application. It is intended that the Preservation District be. applied to all naturally and artificially made coastal and non coastal bodies of water and wetlands of including spoil islands, spoil banks, basins, bays, bayous, canals, streams, creeks, ponds, ~wamps, marshes, bogs, lakes and rivers, whether publicly or privately owned. The Preservation District shall apply to all surface waters and submerged lands thereunder (for coastal waters, submerged lan~ be considered those lands seaward from the established line of mean high tide). Furthermore, the Preservation District shall be applied to all upland areas 30 feet landward of mean high tide where mangroves exist. (Mangroves are.recognized of special ecological value to the city and are defined in section 98.01 of the Clearwater Code of Ordinances.) Sec. 40.583. Permitted uses. Within Preservation Districts, only the- fallQwing...use.s... (and structures designed for such uses) shall be permitted: (1) Recreation activities which are not environmentally di~ptive. (2) Public projects directed by the city COmmiSSiOl1; (3) Docks. Sec. 40.584. Conditional uses. Within preservation districts, the following uses may be. permitted as conditional uses: (1) Marinas; (2) Recreation activities other than those ~ted as permitted uses; (4) Utility facilities. Sec. 40.585. Use limitations. The following use limitations shall apply to.. aquatic lands/coastal districts: (1) No dredging or filling nor the removal of established native vegetation shall be permitted 84 I I I I I I I I I I I I I I I I I I I except as may be specifically authorized by the city commission, the U.S. Army Corps of Engineers, and the state. (2) Docks shall be governed by all terms contained in section 41.151. (3) No commercial activity, including the sale or renting of any slips, launching facilities, or living aboard any boat, whether permanently or temporarily, shall be permitted unless the facility abuts upland property assigned a commercial zoning district, public/semipublic district or urban center district and, furthermore, the activity or use is specifically authorized by the planning and zoning board. Sec. 40.587. Applicable county and state requirements. (1) Nothing in this division shall be construed to abrogate or otherwise deprive the county water and navigation control authority of its jurisdiction, powers and duties as conferred by law. (2) The application of all provisions of this division shall be cumulative and complementary to state law. PREVIOUSLY REFERENCED SECTION 42-28 Sec. 42.28. Vegetative buffer adjacent to preservation district or jurisdictional wetlands. (1) A vegetative buffer, being necessary to protect the ecological and aesthetic integrity of interior or coastal wetlands, shall encompass all lands within 25 feet of the boundary of any property designated on the zoning atlas as Preservation (P), or any property determined to be wetlands under the jurisdiction of the State of Florida ("jurisdictional wetlands ")~ and all lands within 15 feet of the top of the bank of any creeks, channels, or related waterways which contain jurisdictional wetlands. For the purposes of this section,"top of the bank" is defined as that point on the slope at which the side slope becomes flatter than one foot vertical to four feet horizontal. However, this requirement shall not apply to p.yi!::ting ~a11s or other structures creating an abrupt transition between any such property and the adjoining upland property. (2) When a proposed development is adjacent to property designated as preservation or determined to be jurisdictional wetlands, the vegetative buffer shall be provided by the owner in accordance with the requirements of this section. The vegetative buffer may be IJrovided within or over other required setbacks. The buffer shall be designated on the site plan, plat or replat of the property as a "Preservation Lands Protection Buffer." (3) Upon approval by the division of environmental management, the required buffer width may be reduced by not more than one-third in ~porti<ID-ofthe.buffer, by providing additional width in another portion of the buffer which will result in an equivalent or greater square footage of cumulative buffer area. (4) No structure or other surface impervious to water shall be permitted within the vegetative buffer, with the exception of structures which would be allowed as a part of a permitted or conditional use within the preserva.tion.-district. 65 I' I I I I I. I I I I I I I I I I I I I ~ (5) A structure or impervious surface existing within a vegetative buffer as of October 4, 1990, and not in compliance with the provisions of this section, shall be deemed lawful but nonconforming if the structure or impervious surface was lawful when constructed. No expansion of the structure or impervious surface into the buffer shall be permitted. If the structure or impervious surface should be substantially damaged, by disaster or otherwise, the reconstruction of the structure or impervious surface within the vegetative buffer shall not be permitted. Nothing in this section shall be construed so as to prevent the ordinary maintenance or repairs of lawful but nonconforming structures or impervious surfaces, regardless of the dollar value of such repairs. (6) Within the vegetative buffer, any native vegetation shall be protected so that the buffer will retain the character of the immediately adjaceru vegetation within the preservation district. Native vegetation within the buffer shall not be removed or altered without the approval of the division of environmental management in accordance with the provisions of this section. If removal or alteration is proposed, the owner shall present a plan for approval by the division of environmental management showing that the proposed removal or alteration of the vegetation will not adversely affect the hydrological or ecological integrity of the adjacent wetland. If approved, the plan shall be incorporated in the approval and the terms thereof shall be binding upon the owner. All prohibited trees as listed in section 52.06(3) existing within the buffer shall be removed by the landowner and shall be prevented from re-emergence. This subsection shall not be construed to prohibit routine maintenance trimming of nonwetland vegetation in accordance with procedures developed by the division of environmental management and approved by the city manager. (7) Any removal or alteration of native vegetation within a vegetative buffer without the approval of the division of environmental management shall be deemed a violation of this section. Each day following the removal or alteration of native vegetation shall be deemed a separate violation until the native vegetation is restored. The code enforcement board shall require the owner to restore the vegetative buffer to its natural state at the owner's expense, and the owner shall be subject to the imposition of a fine in an amount not to exceed $100.00 per day for each day that the owner is found to be in violation of this section.

Readings were taken over: ~",ur hour period in order tv capture most traffic conditions and to develop reasonable averages, peaks,. and low readings. Standard decibel recording methods were used. Readings were taken at several locations in order to establish ambient levels, traffic source levels, distance attenuation, and vegetative attenuation. Readings taken along the edge of the pavement were highest and most variable. Noise levels rose and fell quickly as different types of motor vehicles passed the monitoring point. Levels only fell below 70 when there was no traffic on the road within approximately SO yards. Noise attenuation is effected by two co-factors: Distance from the source and physical structures which disrupt noise transmission through. the atmosphere. In the first instance, losses are due primarily to the energetics associated with compression waves. In the second instance, the compression waves are partially disrupted by passing through foliage. Both of these factors will affect sound differently dependant upon the initial amplitude and frequency of the sound. Typically lower frequency sound will travel further than higher frequency sound. The amplitude of the compression wave is also a factor and high compression ratio sound waves (high amplitude: e.g. backfire) will often travel farther than low compression ratio waves. Examination of the data leads to the conclusion that the affect of distance was significant after only 12 yards. The data indicate that the most dramatic effect was not the overall attenuation but the lowering of the bottom end of the range of readings. This may be interpreted as being quieter when there is little traffic but not much quieter when there is a lot of traffic. The impact to the habitat resident is that it is generally quieter for a longer period of time, but when it is loud it is nearly as loud as it is at the roadside. Vegetation attenuates noise pursuant to the thickness of the vegetation and the physical structurt: of the plants. The oleander attenuated a significant level of noise even when close to the """'dside because the plant has thickly nllll"..ed leaves. Mangrove~ "'1 the other hand, have fewer leaves per unit volume of space occupied by the plant and attenuates less sound. The combination of vegetation and distance was most effective at reducing noise levels. Readings were also taken on the water side of the mangroves to determine ambient over water noise from waves on the shore. What is noteworthy is that even a modest amount of vegetation in combination with only 20 yards (mol) of distance attenuation, is sufficient to reduce peak levels to near ambient conditions. It is also important to note that.the attenuation does not make the noise less detectable by man or fauna, but makes it less of a shock. The attenuation therefore does not eliminate the sound of the road itself but can eliminate th~ disruption associated with the intensity 72 File: Delta Seven Ine memcwy28 I I I I I I I I I I I I I I i I I I il of the sound. The attenuation of the peak sound levels is relevant to disruption as it reduces the overall noise. The attenuation oflow end sound, however, may be even more significant. This latter attenuation means that the frequency of disturbance is lowered. A seagull may emit a cry as loud as 75 db. One gull crying periodically is typically not considered disturbing whereas a flock emitting a more or less constant frequency of cries is irritating even though the actual noise levels may retain the same peak values.

APPLICATION: The mangrove habitat aPd it's associated wildlife usage may be improved by the thick placement of upland plants between the mangroves and the road. Such planting should be given mitigative credit as an enhancement to an impaired site. 73 File: DeJ1a Sevm Ine mancwy28 I I I I I I I 1\ 'I I I I I I I I I ,I: , , PINELLAS COUNTY DEPARTMENT OF ENVIRONMENTAL MANAGEMENT 512 S.

Box 3241 St. Petersburg, FL 33731 RE: Mangrove Trimming Rules and Guidance Dear Tom: This letter is in response to the questions you have regarding the Mangrove Trimming and Preservation Act (the Act.) I apologize for the delay in responding, but we had not dealt with any of these issues you are inquiring about since the Department of Environmental Management (DEM) received delegation from the Department of Environmental Protection in 1996. Your questions and the answers to them are as follows: 1. "What recourse (a,ppeal) is available to a mangrove trimming permit applicant should a request to trim and/or alter mangroves be denied?" Any appeal of a permit denied by Pinellas County DEM will be addressed in Section 403.9327 (5), Florida Statutes (1997), which specifies that review of permit denials are subject to Chapter 120. 2. "What variance opportunities exist and how is an application for a variance initiated?" Variances are referred to in Section 403.933, Florida Statutes (1997) and have been incorporated into the Pinellas County Land Development Code at Section 166-1 04.:Ibat section states that the delegated local government may grant a variance from the provisions of the Act if compliance therewith would impose a unique and unnecessary hardship on the owner or any other person in control of the affected oroperty. Relief may be granted upon demonstration that such hardship is not self-imposed and that the grant of the variance Will be consistent with the general intent and purpose of the Act. The delegated local government may grant variances as it deems appropriate. Thus, Pinellas County, as a delegated local government, has been granted a great deal of latitude in granting or denying any request for a variance to the terms of the Act. .Pinellas County is an Equal Opportunity Employer" · Member-Pinellas Partnership for a Drug FreeWorkplace 0 printed on recycled paper I I I I I I I I I Ii I I I I I I I I j Page -2- Mangrove Trimming Rules and Guidance Continued The Department of Environmental Management has not yet seen an application for a variance to the terms of the Act. However, any application would need to state, along with all necessary general information, what Section of the Act it is seeking a variance from, what unique or unnecess?ry hardship would be imposed on tne owner by a strict application of the terms of the Act, and a demonstration that such hardship is not self-imposed. 3. "Does the habitat mana~ement criteria of Pinellas County Land Development Code Chapter 166. Article 2 ap,ply for criteria for issuance of a man~ove trimmin~ permit?" Although the Act has been incorporated into the Pinellas County Land Development Code, it is not the intent of the County to impose stricter criteria than that already set out in the Act itself. This intent is expressed in Section 166-102, which states that ''the regulation of mangrove protection under this division is intended to be complete and effective without reference to or compliance with other statutory or code provisions". Based upon this, the habitat management criteria of Chapter 166, Article 2 does not apply to the mangrove trimming requirements; therefore, the only criteria the County will use in acting upon an application to trim mangroves will be those criteria set forth in the Act. Of course, the County's delegation agreements as well as Section 403.9324 (6), Florida Statutes (1997), allows for the imposition of more stringent criteria by the County, so that is always an option in the future.

OL Box 4748 Clearwater, Florida 335i8 RE: Section 15220, SR 60 Memorial Causeway Dear Mr. Crawford: Per your meeting with members of the traffic operations staff on June 30, 1983, we are in the process of preparing the necessary documentation to prohibit parking within twenty feet (20 ft.) of the pavement on the above referenced section of roadway, from M.P. 0.305 (east end of Br. No. 43) to M.P. 1.959 (AlL 19). Based on our right~~f-way information and information provided to us by the City and the County, the causeway is owned by the City of Clearwater. . Therefore, our jurisdictional responsibility is limited to the area required for maintenance of the roadway and shoulder. If the City decides to proceed with formally recording a portion of the Causeway area as Florida Department of Transportation right-of-way, wer~quest that the area recorded be specified as a 130 ft. total ~idth along centerline of existing roadway. This will allow sufficient right-of-way to pro~ide for the six lane divided section proposed for the year 2000. If you have any questions or we may be of further assistance, please advise. ;1~PiIt 00 Uc4- I I' I cc: Mr. A. L. Mr. L. M. Mr. James I Shoemaker Courtney G. Kennedy C. W. Monts De Dca, P.E.

As we discussed, the proposed work appears to be outside our jurisdictional limits for this roadway. According to our records, the 1,200 feet Memorial Causeway R/W is not owned by the S~ate. I have attached July II, 1983 letters from Mr. ~onts De Oca and Mr. Lott that outline our responsibilities on this roadway. As the proposed signs appear to be outside our maintenance limits (20 f~et from edge of pavement) and would be outside the required clear zone for this roadway (18 feet from edge of travel lane, 14 feet from edge of auxiliary lane), we do not feel that the FOOT can legally issue a permit for the proposed work.

APPENDIX 10 Salient excerpts ofCh 403.9322, LoF "Mangrove Trimming and Preservation Act." Emphasis added. 403.9322(1) The Legislature finds that there are over 555,000 acres of mangroves now existing in Florida. Of this total, over 80 percent are under some form of government or private ownership or control and are expressly set aside for preservation and conservation purposes. 403.9323(2) It is the intent of the Legislature that no trimming or alteration of mangroves may be permitted on uninhabited islands which are publicly owned or on lands set aside for conservation and preservation, or mitigation, except where necessary to protect the public health safety, and welfare, or to enhance the public use of, or access to, conservation areas in accordance with approved management plans. 403.9325(6) "Public lands set aside for conservation or preservation" meanS: (I) Public lands designated as conservation or preservation under a local government comprehensive plan; 403.9325(7) ''Riparian mangrove fringe"...does not include mangroves on ... public lands that have been set aside for conservation or preservation.... 403.9328(2)(a} The department, when deciding to issue or deny a permit for mangrove alteration or trimming under this section, shall use the criteria in section 373.414(1) and (8). 78 File: Della Seven Ine memcwy28 I I' I I I I I I I I I I, I I I I I I I APPENDIX 11 Tinney Creek permit as a precedent Tinney Creek Permit Permit # 3.97.259M received 3-20-97. This permit is for the removal mangroves to create a 50' wide clear zone in the creek and an additional unspecified width of topping and hedging for unstated reasons, perhaps for maintenance access. The stated need is to provide for adequate drainage. The application does not contain figures for the acres proposed for trimming. Fee was waived. FS 403.9323(2) It is the intent of the Legislature that no trimming or alteration of mangroves may be permitted on uninhabited islands which are publicly owned or on lands set aside for conservation and preservation, or mitigation, except where necessary to protect the public health, safety, and welfare, or to enhance public use of, or access to, conservation areas in accordance with approved management plans. In the Tinney Creek case a permit was issued on lands set aside as conservation or preservation but the lands were privately held. In the quote from the statute above, the critical interpretative point is on the word "or" in line 2. The qualifier of public lands occurs prior to the "or" and the conservation lands occurs after the "or." This indicates that both public and private lands in preservation or conservation should be restricted from trimming activities. If this argument is supportable, the Tinney Creek permit sets precedent relevant to the Causeway project. If the county argument that the lands must be in public ownership is supported then the Tinney Creek permit does not set precedent. Regardless of precedent, the intent clearly opposes the trimmina of the mangroves on the causeway. The county, however, has stated that they will not accept past permitting as precedent to loosen the prohibition. 79 File: Delta Seven IDe mancwy28 1 I I I I I I I I I I I I I I' I I , I I APPENDIX 12 Excerpts from Chapter 373.414 Public Interest 373.414 Additional criteria for activities in surface waters and wetlands.-- (1) As part of an applicant's demonstration that an activity regulated under this part will not be harmful to the water resources or will not be inconsistent with the overall objectives of the district, the governing board or the department shall reQ!1ire the apQlicant to provide reasonable assurance that state water quality standards applicable to waters as defined in s. 403.031 (13) will not be violated and reasonable assurance that such activity in, on, or over surface waters or wetlands, as delineated in s. 373.421(1), is not contrary to the public interest. However, if such an activity significantly degrades or is within an Outstanding , Florida Water, as provided by department rule, the applicant must provide reasonable assurance that the proposed activity will be clearly in the public interest. (a) In determining whether an activity, which is in, on, or over surface waters or wetlands, as delineated in s. 373.421(1), and is regulated under this part, is not contrary to the public interest or is clearly in the public interest, the governing board or the department shall consider and balance the following criteria: 1. Whether the activity will adversely affect the public health, safety, or welfare or the property of others; 2. Whether the activity will adversely affect the conservation offish and wildlife, including endangered or threatened species, or their habitats; 3. Whether the activity will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; 4. Whether the activity will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; 5. Whether the activity will be of a temporary or permanent nature; 6. 'Whether the activity will adversely affect or will enhance significant historical and archaeological resources under the provisions ofs. 267.061; and 7. The current condition and relative value of functions being performed by areas affected by the proposed activity. (b) If the applicant is unable to otherwise meet the criteria set forth in this subsection, the governing board or the department, in deciding to grant or deny a permit, shall consider measures proposed by or acceptable to the applicant to mitigate adverse effects that may be caused by the regulated activity. Such measures may include, but are not limited to, onsite mitigation, off site 80 File: Deha Seven Ine memcwy28 I I I I I I I I I I I I I I I' I I I I mitigation, off site regional mitigation, and the purchase of mitigation credits from mitigation banks permitted under s. 373.4136. It shall be the responsibility of the applicant to choose the form of mitigation. The mitigation must offset the adverse effects caused by the regulated activity. 81 File: Deha Seven IDe mc:mcwy28 I I I I I I I I I I I I I I I I I I I APPENDIX 13 Excerpts from Chapter 373.414(8) Cumulative Impact Criteria (8) The governing board or the departmer+ :n deciding whether to grant or deny a permit fnr ~'1 activity regulated under this part shall consider the cumulative impacts upon surface water and wetlands, as delineated in s. 373.421(1), within the same drainage basin as defined in s. 373.403(9), of ( a) The activity for which the permit is sought.
