Resolution 068-1985 .. RE.$~cutl~N N~. 068 - 1985 IDHEREA.$, the B~ARD ~f t~UNty t~mml.$.$I~NER.$ ~f m~NR~E t~UNty, fC~RIDA, has receiveD an application from Henry A. Amaon, anD IDKEREA.$, in compliance with .$tate .$tatute, it is necessary as part of the permitting proceDure to reaD the following Biological Assessment into the RecorD, as follows: The applicant would like to provide improved boat mooring facilities at his canal front residential property. In order to accomplish this goal, the applicant proposes to excavate a boat slip along the shoreline of his property. The proposed boat slip will measure 40 ft. long, parallel to the shoreline, and 15 ft. wide and 6 ft. mean low water (MLW) deep. Approximately 190 yd3 of material will be excavated, virtually entirely landward of mean high water (MHW), in order to create the slip. The applicant's estimate of 1,200 yd3 of excavation appears to be very high. No information on how the proposed construction work will be accomplished is provided with the application. Information on how the spoil will be disposed of is particularly absent. No information on how water quality will be maintained while the project is under construction, has been provided. The project site is located in the Rock Harbor area of Key Largo in the Key Largo Ocean Shores Subdivision. Most of the subdivision is oriented toward single family residences, however, sections of it are developed with business and multi-family residences. The majority of lots within the subdivision are canalfront. A network of three canals runs through the subdivision. The canals connect to the Atlantic Ocean within John Pennekamp Coral Reef State Park at their eastern end and Rock Harbor, also within the park, at their western end. A private canalfront residence occupies the lot which borders the west side of the applicant's property. Boat mooring facilities are provided for this residence by a large boat basin on the side of the canal. To the east, the applicant's property is bordered by a vacant lot covered by a mixture of buttonwood trees (Conocarpus erecta), sea daisy (Borrichia frutescens), sea purslane (Sesuvium portulascastrum), and knot grass (Paspalum distichum). The south side of the applicant's property is bordered by Lorelane Place which provides overland access to it. To the north, the applicant's property is bounded by a canal. Both the waters within the canal and in Rock Harbor and the Atlantic Ocean, at the end of the canal, are designated as Class III Florida Waters (Chapter 17-3.081 and 17-3.161, Florida Administrative Code). The waters of John Pennekamp Coral Reef State Park have the additional designation of Outstanding Florida Waters, (Chapter 17-3.041, Florida Administrative Code). Key Largo Ocean Shores subdivision has been the location of several recent projects permitted by the Department. The most noteworthy among these is Permit Number 44-34296, issued on April 23, 1982, to Mr. Robert Krieter which authorized the dredging of one of the three canals within the subdivision. Resolution No. Henry A. Amoon Page two The applicant's property consists of a 70 ft. by 120 ft. canalfront lot with the long axis oriented perpendicular to the canal shoreline. The ground is quite flat on the lot at an elevation of approximately one foot above mean high water (MEW). Substrate on the lot consists of a very thin layer of crushed rock fill over Key Largo limestone bedrock. High points in the bedrock shows through the fill at many locations. The canal was excavated through the bedrock adjacent to the applicant's property, in a manner which resulted in a near verticle but very jagged canal wall. Depths within the canal typically run around eight to ten feet MLW. A signi- ficant tidal head difference exists between the Atlantic Ocean and the Rock Harbor end of the canal. The result of this head difference is relatively high current volocities within the canal. The high current velocities and generally good flushing characteristics of the canal, have in turn resulted in favorable water quality conditions. The flora on the lot can be divided into three general cat- egories. One of these categories is the canal edge, dominated by a row of buttonwood trees which typically run around 15 ft. high with an understory composed of sea daisy and sea purslane. The remaining two categories of flora account for the remaining area of the lot. In both of these two areas, the lot is covered by numerous but widely spaced buttonwood trees, along with one or two Florida Holly trees (Schinus terebinthifolius). The distinguishing character- istics that separates the two areas is the ground cover. On roughly the eastern half of the lot, the ground cover around the trees is dominated by sea daisy. On the northern half of the lot, the ground cover is dominated by the fringerush Fimbristylis spathacea and Sporobolus domingensis. The difference in the ground cover on the eastern and western halves of the lot appears to be caused by the western half having been mowed periodically in the past. A few scattered patches of sea purslane were observed on both sides of the lot and an area vegetated by knotgrass (Paspalum distichun) runs along the road. The remains of what appeared to be a very old wrack line (i.e. at least several months old), was located in the central portion of the lot. Construction related activities are likely to result in temporarily elevated levels of dissolved organic compounds, particulate organic compounds, and turbidity in the waters surrounding the project site. The applicant has not indicated any plans to utilize any controls that would result in a reduction of this impact. Without proper controls, the strong currents in the canal are likely to carry the pollutants, generated by the construction activities, far and wide. Once the boat slip is complete and in use, it will facilitate a more intense level of use of the canal. Increased discharges of toxic metals, hydrocarbons, detergents, organic compounds and miscellaneous debris can be expected to result. The magnitude of the increase of these discharges is not expected to be very great and the strong flushing currents in the canal are expected to keep the levels of these pollutants at acceptable levels. Resolution No. Henry A. Amoon Page three Although the application does not state where the spoil generated by the proposed work will be placed, it seems likely that it will end up on the applicant's lot. Spoiling on the applicant's lot will tend to destroy the wetlands which presently cover much of it. Additionally, the operation of construction equipment on the lot, while the slip is being excavated, is likely to scarify the wetlands on the lot. It is therefore likely that a secondary im~act of the proposed work will be damage to or loss of the wetlands on the applicant's property. With the loss of the wetlands will also be the loss of the associated functions of primary production, habitat and pollution filtration. In the case of the project site, these functions are represented moderately well.

SITE AND PROJECT DESCRIPTION: This application for the excavation of a boatslip involving 190 yards of excavated material and which will effectively extend navigable waters should be reviewed by the Board of County Commissioners pursuant to section 19-111 (b) (4) of the Monroe County Code. All of the excavation will be landward of the Mean High Water Line (M.H.W.L.). The site in question was inspected on 12-20-84 and resulted in the following: the parcel does not fall within the Shoreline Protection Zone (S.P.Z.) as defined by section 4-18 of the Monroe County Code. The lot abuts residential lots on the south, west, and north. To the east the property abuts a subdivisional canal. The lot was sparcely vegetated with Florida Holly (Schinus terebinthefolius}, buttonwood (Conocarpus erectus), Batis, sea oxeye daisy, (Sesuvium portulacustrum), and a few scattered red mangroves (Rhizophora mangle). This type of vegetation indicates that the lot is in a transition upland-wetland zone. The lot was cleared without benefit of permit. An after-the-fact permit was issued on 1-2-85. The applicant proposes to place all dredge spoils on the upland portion of his property. Exactly how the excavation will be per- formed, ie. from the upland or from the canal, is unknown. Currently the adjacent property owner has a similar boat basin. III. EVALUATION: The anticipated long term impact on the environ- ment should be minimal. Due to the good flushing action of this canal, the impact of increased hydrocarbon load (fuel) should not present a problem. Since the subtidal vegetation present is minimal it is expected that little difference will be exhibited by the exca- vation of this boat slip. The short term impact will be one of temporarily raised levels of turbidity. ~ This could be controlled with the use of tur~idity screens if properly employed. -1- Jeffrey Doyle Amoon, excavation, boatship January 30, 1985 IV. RECOMMENDATION: The biologist recommends approval. Conditions: 1) 2) Turbidity screens to be employed. The boat slip shall not exceed -5' ML~. V.
