Resolution 180-1985 ;"-'-". RE$~CUtI~N N~. 180 -1985 WHEREA.$, the B~ARD ~c ~CUNtg C~mmI$I$~NER$ ~f m~NR~E C~UNtg, fC~RIDA, has receiveo an application from WICCIAm $ICER & C~RREttA tH~mP$~Nano, WHEREA.$, in compliance with $tate $tatute, it is necessary as part of the permitting proceoure to reao the following Biological Assessment into the Recoro, as fallows: The applicant would like to provide improved boat mooring facilities for two residential canal front lots. The applicant's goal will primarily be achieved by the excavation of a single boat slip which will extend across the canal shoreline of both lots. The slip will measure 116 ft. long by 15 ft. wide and will match the canal depth of 4 ft. mean low water (MLW). Both ends of the slip will be flared at a 450 angle, apparently for the purpose of improving water circulation. The sides of3the boat slip will be vertically box cut into bedrock. An estimated 450 yd of bedrock and crushed rock fill will be excavated from t 0.035 ac area above mean high water (MEW) in order to create the boat slip . A pair of 10 ft. wide by 30 ft. long boat ramps will be built along the boat slip side. The boat ramps will be located one on either lot, with a six foot wide wall separating them. The sides of the proposed boat slip will be saw cut into bedrock. A five foot wide concrete walkway will be constructed around the edge of the slip. Excavation of the slip will be accomplished by using a backhoe. The spoil will be placed in uplands on one of the lots. Turbidity curtains will be used to maintain water quality while the work is in progress. The project site is located in the Rock Harbor area of Key Largo in the Key Largo Ocean Shores subdivision. Until approximately two years ago, the subdivision consisted of two pairs of canals which run due east to west. The canals connect to the Atlantic Ocean to the east and Rock Harbor to the west. Approximately two years ago, a third pair of canals were dug parallel to and to the south of the older pairs. Permit No. 44-34296 was issued on April 23, 1982, authorizing the new pair of canals. It is within this pair of canals where all of the proposed work will take place. The new canals do not connect directly to the ocean or Rock Harbor, but rather connect at either end to the middle of the three canal pairs to the north. The middle canal, in turn, provides direct access to Rock Harbor and the Atlantic Ocean. The Atlantic Ocean end of the canal system is provided with an access channel, however, the Rock Harbor end terminates in very shallow water (exposed at low tide), such that all boat traffic has to go in and out through the ocean access channel. The central canals are connected by a small bridge at their landward ends, which allows small boats to pass. As mentioned above, the southern pair of canals where the proposed work is located, were constructed within the last year. To date, only a few lots have been built on in this new section of the subdivision. In the older areas to the north, approximately half of the available lots have been developed. The primary type of development is private residences, however, there is a central area which is developed commercially. Both the Atlantic Ocean and Rock Harbor, where the Key Largo Ocean Shores subdivision's canals connect to them, are within John Pennekamp Coral Reef State Park. The waters of the park are designated as Class III, Outstanding Florida Waters (Chapters 17-3.041, 17-3.081 and 17-3.161, Florida Administrative Code). IThe applicant's volume estimate appears to be low. Resolution No. William Siler & Lorretta Thompson Page Two On May 16, 1983, application number 440697669 was received by the Department. This application requested authorization to build a boat slip, which is identical to the one proposed by Mr. Siler, on a pair of lots a few hundred feet to the west of the applicant's property. To date, no final agency action has been taken on this application. The project site consists of two adjoining 70 ft. by 122.5 ft. lots (0.197 ac each) canal front lots with their long axis oriented perpendicular to the canal shoreline. A private residence has recently been built on the eastern- most of the two lots. The western lot remains vacant. Various ornamental planting have been installed around the residence on the eastern lot, however, much of this lot and all of the western lot, consists of scarified fill with only a few oportunistic plants. Along the canal edge, a few salt tolerant plants including sea purslane (Sesuvium portulacastrum), seaside heliotrope (Heliotropium curassavicum), sea daisy (Borrichia frutencens) and red mangrove (Rhizophora mangle) seedlings have tentatively established themselves. The canal sides were cut at a steep, but not vertical angle, such that the maximum depth of the canal is not reached for a few feet from the upper bank. As previously mentioned, the canal on which the proposed work is located, is open at both ends. The canal takes advantage of a tidal head difference between the Atlantic Ocean and Rock Harbor, to provide a strong flushing current. Measurements of water quality within the canal have favorable reflected this. Construction related activities are likely to result in temporary elevated levels of turbidity, in the waters near the project site. Proper use of turbidity screens, as proposed, should be able to control this impact within acceptable levels. The biota, which is presently found living in the area of the proposed boat slip, will be eliminated by the construction of the slip. Eventually, a similar biota should be able to establish itself in and around the new boat slip. The proposed boat slip will tend to create a shoreline discontinuity and stagnant pocket of water. Orienting the long axis of the slip parallel to the canal and flaring the ends of the slip will tend to minimize this impact.

INTRODUCTION: This application for the construction of a boat slip which involves excavating 222 cubic yards of material should be reviewed by the Board of County Commissioners purusant to Section 19-111 (b) (4) of the Monroe County Code. II. SITE AND PROJECT DESCRIPTION: The applicants propose to excavate a boat slip on their adjoining properties. This excavation will effectively extend a navigable body of water and as such, pursuant to Section 19-1ll(b) (4) of the Monroe County Code, review by the Board of County Commissioners is required. The project will involve an excavation of 222 cubic yards of material. In addition to the boat slip, a boat ramp is being applied for. The Florida Department of Environmental Regulation (F.D.E.R.) has permitted the two boat slips as a single project (see enclosure). The site in question was inspected on 4-26-85 and resulted in the following: The lots are bordered on the north, south, and east by residential property. To the west lies the major development Hidden Bay. The lots do not fall within the Shoreline Protection Zone (SPZ) as defined in Section 4-18 of the Monroe County Code. The lots have been previously scarified with very little vegetation present. Sub- tidal vegetation as well was depauperate. The reason for this is that this area is a relatively new subdivision in which little erosion has occurred. Ill. EVALUATIO~: The antjcipated impact of excavilting a boat slip should not be significantly Llrge. Since this c:mal system does exhibit il large tidal flux, a good flushing action is present. It is Page Two May 10, 1985 Thompson, Siler, boat basins anticipated that an increase in petrochemicals will occur due to the utilization of motor boats. This should not be significant as a good flushing action is present in the canal system. A temporary rise in the level of turbidity should ensue during construction. This rise could be controlled with the proper use of turbidity screens. Runoff into the basin as well could be controlled if a reverse swale embank- ment be constructed such as to stop runoff into the water. IV. RECOMMENDATION: The biologist recommends approval. Conditions: (1) Turbidity screens to be employed during construction. (2) A reverse swale embankment to be con- structed to control storm water runoff into the basin. V. OTHER: The applicants have applied for and received permits from the F.D.E.R. and the U. S. Army Corps of Engineers.
