Resolution 300-1981 RESOLUTION NO. 300, -1981 WHEREAS, the BOARD OF COUNTY COMMISSIONERS OF MONROE COUNTY, FLORIDA, has received an application from Monty Sink and WHEREAS, in compliance with State Statute, it is necessary as part of the permitting procedure to read the following Biological Assessment into the Record, as follows: The applicant is proposing the construction of a seawall along a residential shoreline for the purpose of protecting said shoreline and providing private boat dockage. The proposed seawall will be constructed waterward to the MLW line. Of the 200 cubic yards to he deposited, 100 cubic yards will be de- posited landward and 100 waterward (MHW). Total length of the sea- wall will be 60 feet. Its width, including backfill, will be approx- imately eight feet. The width of the concrete cap will be four feet. Tiebacks will be used to stabilize the proposed seawall. The project site is located on the western side of Summerla~d ~ey near Kemp Channel within what is referred to as summe~land C ve. Summerland Cove has been extensively developed for si family re- sidences with a network of inland man-made canals and a perimeter channel which provides deep-water access for the resid tial community. Waterward of this deep perimeter channel, the depths sha ow to two (2) feet or less. The benthic community over these flats i some- what unstable with patches of seagrasses and algaes. Beca~se of this instability, water transparency within Summerland Cove~ some- what less than that found elsewhere in the Keys. In the more immediate vicinity of the applicant, development of the waterfront lots along Carribena Drive is somewhere in the vicinity of 30 to 40 percent. It is likely that the spoil obtained from the dredging of the offshore perimeter channel was deposited along the existing residential lots, forming erosion-prone marl shorelines. As a whole, the shoreline in this area has undergone some erosion, although it is not nearly as severe as it could be due to an original Miami oolite base, which is exposed below MHW, and a well- compacted 1 imestone..marl overburden. Because of the absence of soft sediments along this shorline, few mangroves have become established. In general, the emergent shoreline vegetation starts above the extreme high water line in the form tran- sitional wetland species, which occupy only a narrow strip before giving way to uplands. The perimeter channel in this area is deeD, box cut, and varies from 60-80 feet in width. The submergent shelf separating the present shoreline from the perimeter channel averages 10-20 feet in width, with limited floral stabilization. The applicant's lot drops from a three to five foot elevation (above MSL) at the erosion line to form an approximate 151 wide littoral shelf, of which six to eight feet is intertidal. At the erosion line, some transitional wetland vegetation was en- countered such as sea daisy (Borrichia sp.) and buttonwood (Conocarpus erecta). From this point, waterward, little vegetation is found, with the exception of several small black mangrove (Avicennis ger- minans) sprouts. Page -J.- r,' 0 n ty Sin k Seawall Page -2- The substrate along this entire shoreline is composed primarily of loose limerock rubble. A good many grazing snails (Nerita sp.) were found here. Among the smaller limerock oarticles were much larger boulder, which attained diameters of up to 1~ feet. Below the MLW line, a variety of submergent flora was observed, in- cluding turtlegrass (Thallasia testudinum), green algaes (Batophora sp. and Halimeda sp.), and brown algaes (Acanthorhora so.). Also observed here were several schoolmaster snapper Lutjanus arodus). The littoral shelf drops off sharply to the channel depths within Summerland Cove. From the point of drooping off, the perimeter channe 1 extends another 50 to 80 feet out. Impacts anticipated should be primarily long term and may include a decrease in runoff filtration, lessened wave energy disnersion and a corresponding increase in wave energies and erosion of littoral commu- nities at the base of the seawall and a decrease in intertidal detri- tal accumulation resulting in lessened sediment build-up and a corresponding decrease in sediment-d~pendent snecies such as seagrasses. Conversely, a degree of stability will be realized from the seawall and due to numerous other seawalls permitted in this area, some- what of a precedent has been set. Th~ above stated negative impacts should be fairly minimal due to the relatively sparse amount of submergent or emergent vegetation and the small amount of wind- blown detrital matter found along this shoreline. BE IT RESOLVED BY THE BOARD OF COUNTY COMMISSIONERS OF MONROE COUNTY, FLORIDA. that the above Biological Assessment has been read into the record and duly considered pursuant to Florida Statute 253.124 by the Board of County Commissioners of Monroe County, Florida, this 19th day of October , 19 81 at a regularly scheduled meeting.

Cantrell Dredge & Fill S~pervisor DER r0rm 17-1.122(50) SINK, MONTY iF44-4243l-5E Monroe County - Summer land Key Page Two A. The applicant is proposing the construction of a seawall along a residential shoreline for the purpose of protecting said shoreline and providing private boat dockage. The proposed seawall will be constructed waterward to the MLW line. Of the 200 cubic yards to be deposited, ~OO cubic yards will be deposited landward and 100 waterward' (MHW). Total length of the seawall will be 60 feet. Its width, including backfill, w~ll be approximately eight feet. The width of the concrete cap will be four feet. Tiebacks will be used to stabilize the proposed seawall. B. The project site is located on the western side of Summer land Key near Kemp Channel within what is referred to as Summerland Cove. Summerland Cove has been extensively developed for single family residences with a network of inland man-made canals and a perimeter channel which provides deep-water access for the residential community. Waterward of this deep perimeter channel, the depths shallow to two (2) feet or less. The benthic community over these flats is somewhat unstable with patches of seagrasses and algaes. Because of this instabilitYiwater transparency-within Surrnnerland Cove is somewhat less than that found elsewhere in the Keys. In the more irrnnediate vicinity of the applicant, development of the waterfront lots along Carribean Drive is somewhere in the vicinity of 30 to 40 percent. It is likely that the spoil obtained from the dredging of the offshore perimeter channel was deposited along the existing residential lots, forming erosion-prone marl shorelines. . As a whole, the shoreline in this area has undergone some erosion, although it is not nearly as severe as it could be due to an original Miami oolite base, which is exposed below MHW, and a well- _ compacted limestone-marl overburden. Because of the absence of soft sediments along this shoreline, few mangroves have become established. In general, the emergent shoreline vegetation starts above the extreme high water line in the form of transitional wetland species, which occupy only a narrow strip before giving way to uplands. TI1e perirneter channel in this area is deep, box cut, and varies from 60-80 feet in width. The submergent shelf separating the SINK, MONTY If44-4243l-5E Monroe County - Summer land Key Page Three present shoreline from the perimeter channel averages 10-20 feet in width, with limited floral stabilization. C. The applicant's lot drops from a three to five foot elevation (above MSL) at the erosion line to form an approximntf' 15' wide littoral shelf, of which six to eight feet is intertidal. At the erosion line, some transitional wetland vegetation was encountered such as sea daisy (Borrichia sp.) and buttonwood (Conocarpus erecta). From this point, waterward, little vege- tation is found, with the exception of several small black mangrove. (Avicennia germinans) sprouts. The substrate along this entire shoreline is composed primarily of loose limerock rubble. A good m~ny grazing snails (Nerita sp.) were found here. Among the smaller limerock particles were much larger boulders, which attained diameters of up to l~ feet. Below the MLW line, a variety of submergent flora was observed, including turtlegrass (Thallasia testudinum), green algaes (Batophora sp. and Halimeda sp~, and br~wn algaes (Acanthophora sp.). Also observed here were several schoolmaster snapper (Lutjanus apodus). The littoral shelf drops off sharply to the channel depths within Sununerland Cove. From the point of dropping off, the perimeter channel extends another 50 to 80 feet out. D. Impacts anticipated should be primarily long term and may include a decrease in runoff filtration, lessened wave energy dispersion and a corresponding increase in wave energies and erosion of littoral communities at the base of the seawall and a decrease in intertidal detrital accumulation resulting in lessened sediment build-up and a corresponding decrease in sediment-dependent species such as seagrasses. Conversely, a degree of stability will be realized from the seawall and due to numerous other seawalls perrnitted in this area, some- what of a precedent has been set. The above stated negative impacts should be fairly minimal due to the relatively sparse amount of submergent or emergent vegetation and the small amount of windblown detrital matter found along this shoreline.
