Resolution 208-1983 . ---- . RE$~CUt!~N N~+ 208 -1983 IDHEREA$, the B~ARD ~f t~UNtM t~mm!$$!~NER$ ~f m~NR~E t~UNtM, fC~R!DA, has receiveD an application from TURTLE KRAALS, LTD. IDHEREA$, 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: This is a revised application which proposes the: 1. Construction of two 136' x 8' docks with 95' x 6' terminal tees. 36 finger piers at 30" wide, ranging from 20' to 34' in length, one 64' x 30" finger pier and approximately 115 mooring pilings associated with the proposed docking. All docks and mooring piles would be placed within an existing flow-through boat basin that was excavated under D.E.R. permit #44-20-0297, issued by the Department of Pollution Control in February of 1974. This permit also authorized some of the dock construction now proposed, although construction was never started. The proposed docks would have 10" x 10" concrete pilings and 2" thick concrete decking. 2. Performance of maintenance work in the existing basin by debris such as a refrigerator, a car, lumber and rocks. understood from the application that no dredging will be for the purpose of deepening the basin. removing It is performed 3. Excavation of 3,700 cubic yards submerged baybottom for a distance of 800 lineal feet, to a depth of -8 ft. MLW and at a width of 60 feet. The material excavated would be spread on the applicant's adjacent upland. Work would be done by dragline from a barge. Dock work would also be done from a barge. No mention is made of dock construction methods. The applicant's basin, access channel, and circulation cut were excavated under appropriate permits in the mid 1970's as they now exist. Depths within the basin and access channel are in the vicinity of -10' MLW. Depths within the circulation cut average between -5' and -6' (MLW). All basin and channel sides were box cut and possess vertical walls. Water circulation is excellent throughout the entire system. The applicant's property is currently being developed for condominium units, with all construction presently confined to the uplands. The basin and channels in question will be used to provide boat mooring for the upland development. Most of the basin and channel excavation was done through upland limerock, although a small mangrove fringe was cut through on either side of this development which borders VaLa Cut on one side and Florida Bay on the opposite side. Vaca Cut is deep with strong tidal currents. Florida Bay has an extremely gradual sloping bottom contour which ranges from 0-8 feet (MLW), supporting a variety of algaes, sponges and corals. The existing access channel extends from the shoreline waterward for a distance of approximately 330 feet. At this point, the water depth is approximately -4' MLW. From this point waterward, depths gradually decrease for another 1500 feet, at which time the depths stabilize at about -8 feet (MLW). The applicant's basin has a fairly uniform botton contour with sparse bottom growth made up of several species of green algae (Caulerpa sp. and Penicillus sp.) The basin and channel walls desplay a variety of sponges, tunicates, mussels, anemones, and an occassional xanthid crab or crawfish (Panulirus argus). Resolution Turtle Kraals, Ltd. Page Two This existing access channel possesses silty fine-grained inorganic sedi- ments of up to three feet in depth, as opposed to surrounding ambient sediments which display course calcareous sands and shell hash of no more than six inches in depth. In addition to the finely grained sediments found at the bottom of the access channel, a layer of loose, decomposing algaes and seagrasses were layered for up to two feet in depth in some areas of the channel. This may have been the result of several previous days of predominantly northern winds blowing in organic debris. Benthis flora in the existing access channel is limited to several species of green algaes (Caulerpa sp., Penicillus sp., and Udotea sp.) and one or two insignificant patches of turtlegrass (Thallasia testudinum). The blades of turtlegrass numbered no more than five in either area and appeared to be extremely stressed (old blades barely protruding through sedimentation). Total extent of benthic vegetation in the access channel was less than one percent of the total benthic area. The area proposed for dredging in Florida Bay displayed a rich biological diversity with a predominance of red algaes and sponges over a firm substrate. Particularly impressive is the variety of sponges here, of which ten different species were counted. These species include the bleeding sponge (Oligocerus hemmorrhages), cake sponge (Ircinia ~trobilina), stiner sponge (Ircinia fasciculate), vase sponge (Ircinia campana), candle sponge (Verongia sp.), green sponge (Haliclona viridus), purple bleeding sponge (Iotrochota birotula), sprawling sponge (Neopetrosia longleyi), loggerhead sponge (Spheciospongis vesparia), and the golf ball sponge (Tethya diploderma). Additional faunal species observed included four species of hard corals, including rose coral (Manicinia areolate), starlet coral (Siderastres radians), porous coral (Porites asteroides), and finger coral (Porites porites); soft corals that included sea plumes (Pseudopterogorgia sp.), sea whips (Pterogorgia anceps), and Plexaurellas (Plexaurella sp.); and an occasional echinoderm gastropod, pelecypod, anemone, arthropod and fish species. The Echinoderms observed include long-spined urchins (Diadema antillarum), thorny starfish (Echinaster sentus), and brittle starfish (family Amphiuridae). The gastropods found here included a horse conch (Pleuroploca gigantes), a cone shell (Conus spurius), and turban shells (Astrea tecta americina). Pelecypods included pen shells (Atrina sp.) and cockles (Laevicarduim mortoni). A single species of anemone (Bartholomea annulate) was observed. Arthropods found included spider crabs (family Majidae), stone crabs (Menippe mercenaria), and spiny lobster. Those fish species observed included porgies (Calamus sp.), snapper (Lutjanus sp.), grunts (Haemulon sp.), mojarra (species unknown) and cowfish (Acanthostracion quadricornis). The benthic vegetative cover over the proposed dredge area was estimated at betwwen 50 to 75 percent. Algaes were the dominant vegetation although occasional patches of turtlegrass were found where sediments were deep enough for their support. Those species of red algae identified included Liagora farinosa, Garcilaria verrucosa, Eucheuma isiforme, Dasya pedicellata, Laurencia sp., Acanthophora sp., and coralline algaes (Lithothamnion sp.). Brown algaes included Dictyotasp. and Padina Spa Green algaes included Penicillus sp., calcareous algaes (Halimeda sp.), Caulerpa sp., Udotea sp. and Dasycladus Spa The water depth over the proposed 800 foot long dredge area dropped from approximately -4 feet MLW to approximately -6.5 feet MLW. Deeper depths are found, in general, to the west of the proposed dredge alignment, although they also shallow up near the existing access channel. Resolution Turtle Kraals, Ltd. Page 3 This area is commercially fished for lobster and occasionally, although on a more recreactional basis, for stone crabs. The area in general provides excellent recreational diving and sport fishing. It provides productive nursery and seasonal feeding areas for a variety of large marine forms and habitat substrate for a myriad of smaller life forms essential in forming the base of the marine food chain. This food chain is essential for the economy and livelihood of South Florida and, particularly, the Florida Keys, where recreation is dependent in great part upon the well-being of the marine community. The primary impact of concern from the proposed project is the direct elimination by dredging of a 48,000 square foot natural marine habitat and its associated productive plant and animal communities. The biological diversity of the present marine population is anticipated to be reduced far below existing levels and well below the levels required by state water quality standards (reduction in biological integrity to less than 75 percent of background levels). Due to the excellent flushing found in the basin, the proposed docks and their anticipated boat usage should not cause significant water quality degradation. Due to the impracticality of turbidity controls in the basin, some short term turbidity problems are expected during piling and mooring placement. Similar, more extensive, turbidity problems should be expected during the excavation of the access channel. It is required that the applicant be modified to exclude any additional dredging of the existing access channel. An additional one to two feet of depth could be obtained by widening the existing circulation cut leading to Vaca Cut. This would have far less long term biological impact (some man- grove wetland and a small amount of submerged bottom would be adversely impacted, although, judging from existing conditions in the circulation cut, regrowth of a viable marine community could be expected). The major concern with an access channel on this side is the extreme currents and the consequential navigational hazzard it would impose. A modification of this sort would have to be reappraised from this standpoint. m; :m R:E.3<"!)(11El trlJ (i!!E BOARD (1))' [('JUN1i11 QXOOtill3553(~TER5 (03' m(OO.1R(OI QXl1lr1T(p]. 3'(~fUA. tijat tijr ahour niologiral Aasrasmrnt qas hrrn rrad into tijr rrrorn and duly ronaidrrrd pursuant to 3'lorida 5tatutr 253.12~ hy tijr Board of [ounty [nttmtisaionrn of {{{onror [ounty. 3'lorida. tlJis 22nd day of July 1983 . at a rrgularly srijrdulrd mrrting.

DEPARTMENTAL CORRESPONDENCE DATE July 6 , 1983 SUBJECT Turtle Kraals , Widening of Circulation Channel To Jeffery M. Doyle , Direc or DEPT Planning & Zoning FROM Andy looten, Biologist ,DEP.T Planning & Zoning LEGAL description Township 65S , Range 33E, Section 32 , Gov' t Lot 1 , U. S. 1 at Vaca Key, Monroe County, Florida, Seawatch Condominium Project Zoned RU3 . This major development made application for Marina structural activities and channel dredging in October of 1982 . Mr. Mark Robertson was the Biologist that handled this area at that time. The Zoning Board had approved plans showing the access channel at the North end of the development ; however, during permit application processing with the FDER, ACOE , and the County, all three regulatory agencies encouraged the widening and deepening of the existing circulation channel (located at the Southeastern part of the development) thereby making it the access channel instead of dredging the North Channel to a -8 ft MLW. The reason for this change was to avoid destruction of productive bay bottom on the North Channel. The attached October 19 , 1982• memorandum from Mark Robertson to Alan Lessler brought to attention the need for the Zoning Board to approve any of these changes to the major develop- ment. During my last site inspection , I observed that the docking facilities within the basin were complete. The developers submitted application to the Zoning Board re- questing this change to the major development and was granted approval at the March 29 , 1983 . meeting of the Zoning Board. On April 4 , 1983 , the Marathon Building and Zoning office re- ceived the attached application from the Turtle Kraals (Sea- watch) development reproposing dredging activity to a -6 MLW at the original access channel. Note the "remarks" section of the application referencing the circulation channel (the activity that was approved by the Zoning Board on March 29) widening : ". . . . the applicant concludes that this approach is not feasible. The problems are economics and safety". It may be logical to assume from the explanations that follow in the "remarks" section that the developers wished to dis- continue pursuit of the circulation channel widening and deepening and therefore submitted an application requesting evaluation of the original proposal. Page 2 • Turtle Kr; cont . . . • It was not brought to my attention until recently , that the Zoning Board approved this circulation cut conversion to an access channel for a change to the major development . There- fore , it appears that ' Seawatch is proposing widening and deep- ening the circulation cut and (with the new application for dredging the north channel) the original access channel so that the development will have dual deep water access channels. I will submit a separate report addressing the latter proposal at another time. Because the widening and deepening of the circulation cut will involve excavation exceeding 100 cubic yards in volume , a decision for permitting this activity is required by the Board of County Commissioners persuant to Section 19-111 (b) (4) of the Monroe County Code. I have visited the site four times and have inspected the area where the excavation would take place. The circulation channel is located at the Southeast corner of the basin and connects into Vaca cut . Because of the hydro- dynamics that have resulted in the opening of. Vaca Cut , a strong current passes through this area. The widening activity (an increase to 50 feet in width) would result in the removal of some native vegetation (e. g. button- woods , white mangrove) however , this line of vegetation is . mixed with exotic plant species and removal would not result - in adverse environmental impact to the area. The dredging and deepening of the circulation cut (to-8 ft . MLW) would result in the disturbance of little marine biota due to the probable lack of ability of marine organisms to colonize on a substrate subject to such high current velocity. Water Quality would also not be a major concern because of the high current velocity of that channel and therefore the constant mixing of , oxygenated water. Only the problem of increased sediment particulates (water turbidity) being introduced into the water column is of concern and this can be greatly minimized by the use of turbidity screens during this activity. Therefore , based on the above considerations , it is recommended that this application be approved with the following conditions : (a) Turbidity screens or curtains be employed to reduced water' turbidity to adjacent waters. (b) The applicants place that spoil material in a loca- tion on the property that has been previously scarified or cleared so that no new land clearing will take place to accom- odate such material. NLMO AN DATE: October 19 , 1932 SUBJECT: Dredge/Fill Permit Application for Turtle Kraals a/k/a Sea Watch (Approved Major Development) TO: Alan Lessler, Director FROM: Mark L. Robertson, Biologist I/ 1Li Please note the attached copy of a County Dredge/Fill permit application for the Turtle Kraals (Sea Watch) Major Development in Marathon. I have no objections to this application on environmental grounds, there are a few minor questions that the applicant should be able to answer for me. I ask your guidance as this application differs from the final approved Major Development Plan in two respects : 1) This Dredge/Fill application proposes to widen and deepen the existing circulation channel in the approved Major Development plan to use it as an access channel . The existing access channel would require offshore dredging to be useful , destroying a large area of seagrass . The Army Corps of Engineers sug- gested this change to lessen the negative impact of channel construction. 2) The proposed dock configuration in the basin is diff- • erent from that shown on the original approved Major Development plan. Please note that the amended final Major Development plan, approved on July 27 , 1981 by the Zoning Board, does not specify any dock configuration. It is my opinion that the new dock configuration would be safer for navigation, given the new access channel location. The ,proposed changes to the final approved Major Develop- ment plan will , in my opinion, lessen the negative environmental impact of channel construction. With this in mind and considering that the change was made at the request of another regulatory agency, can these changes to the approved Major Development plan be approved without a Zoning Board hearing?

PERM 16-10 (Rev. 6/79) • J 111111 • TURTLE KRAALS , LTD. #44-42081-5E Monroe County - Marathon Shores Page Two A. This is a revised application which proposes the: 1. Construction of two 136 ' x 8 ' docks with 95 ' x 6 ' terminal tees , 36 finger piers . at 30" wide, ranging from 20' to 34' in length, one 64' x 30" finger pier and approximately 115 mooring pilings associated with the proposed docking. All docks and mooring piles would be placed within an existing flow-through boat basin that was excavated under D.E.R. permit #44-20-0297 , issued by the Department of Pollution Control in February of 1974. This permit also authorized some of the dock construction now proposed, although con- struction was never started. The proposed docks would have 10" x 10" concrete pilings and 2" thick concrete decking. 2 . Performance of maintenance work in the existing basin by removing debris such as a refrigerator, ,a car, lumber and rocks . It is understood from the application that no dredging will be performed for the purpose of deepening the basin. 3 . Excavation of 3 , 700 cubic yards submerged .baybottom for a distance of 800 lineal feet, to a depth of -8 ft. MLW and at a width of 60 feet. The material excavated would be spread on the applicant' s adjacent upland. Work would be done by dragline from a barge. Dock work would also be done from a barge . No mention is made of dock construction methods . B. The applicant's basin, access channel, and circulation cut were excavated under appropriate permits in the mid 1970 ' s as they now exist . Depths within the basin and access channel are in the vicinity of -10 ' MLW. Depths within the circulation cut average between -5 ' and -6 ' (MLW) . All basin and channel sides were box cut and possess vertical walls . Water circulation is excellent throughout the entire system. The applicant'•s property is currently being developed for condo- minium units , with all construction presently confined to the uplands . The basin and channels in question will be used to provide boat mooring for the upland development. Most of the basin and channel excavation was done through upland limerock, although a small mangrove fringe was cut through on either side of this development which borders Vaca Cut on one side and Florida Bay on the opposite side. TURTLE KRAALS , LTD. #44-42081-5E Monroe County - Marathon Shores Page Three Vaca Cut is deep with strong tidal currents . Florida Bay has an extremely gradual sloping bottom contour which ranges from 0-8 feet (MLW) , supporting a variety of algaes , sponges and corals . The existing access channel extends from the shoreline waterward for a distance of approximately 330 feet. At this point, the water depth is approximately -4' MLW. From this point waterward, depths gradually decrease for another 1500 feet, at which time the depths stabilize at about -8 feet (MLW) . C. The applicant ' s basin has a fairly uniform bottom contour with sparse bottom growth made up of several species of green algae (Caulerpa sp . and Penicillus sp. ) . The basin and channel walls display a variety of sponges , tunicates , mussels , anemones , and an occassional xanthid crab or crawfish (Panulirus argus) . This existing access channel possesses silty fine-grained inor- ganic sediments of up to three feet in depth, as opposed to surrounding ambient sediments which display course calcareous sands and shell hash of no more than six inches in depth. In addition to the finely grained sediments found at the bottom of the access channel, a layer of loose, decomposing algaes and seagrasses were layered for up to two feet in depth in some areas of the channel. This may have been the result of several previous days of predominantly northern winds blowing in organic debris . Benthic flora in the existing access channel is limited to several species of green algaes (Caulerpa sp . , Penicillus sp, and Udotea sp . ) and one or two insignificant patches of turtlegrass (Thallasia testudinum) . The blades of turtlegrass numbered no more than five in either area and appeared to be extremely stres- sed (old blades barely protruding through sedimentation) . Total extent of benthic vegetation in the access channel was less than one percent of the total benthic area. The area proposed for dredging in Florida Bay displayed a rich biological diversity with a predominance of red algaes and sponges over a firm substrate. Particularly impressive is the variety of sponges here , of which ten different species were counted. These species include the bleeding sponge (Oligocerus hemmorrhages) , cake sponge (Ircinia strobilina) , stinker sponge (Ircinia fasciculata) , vase sponge (Ircinia campana) , candle sponge (Verongia sp . ) , green sponge (Haliclona viridis) , purple bleeding TURTLE KRAALS , LTD. #44-42081-5E Monroe County - Marathon Shores Page Four - sponge (Iotrochota birotula) , sprawling sponge (NeoVetrosia longleyi) , loggerhead sponge (Spheciospongia vesparia) , and the golf ball sponge (Tethya diploderma) . Additional faunal species observed included four species of hard corals , including rose coral (Manicinia areolata) , starlet coral (Siderastrea radians) , porous coral (Porites asteroides) , and finger coral (Porites porites) ; soft 'corals that included sea plumes (Pseudopterogorgia sp. ) , sea whips (Pterogorgia ance s) , and Plexaurellas (Plexaurella sp . ) ; and an occasional ec ino erm, gastropod, pelecypod, anemone, arthropod and fish species . The Echinoderms observed include long-spined urchins (Diadema antillarum) , thorny starfish (Echinaster sentus) , and brittle starfish (family Amphiuridae) . The gastropods found here inclu- ded a horse conch (Pleuroploca gigantes) , a cone shell (Conus spurius) , and turban shells (Astrea tecta athricina) . Pe cypods included pen shells (Atrina sp . and c—o les (Laevicarduim mortoni) . A single species of anemone (Bartholomea annulata) was observed. Arthropods found included spider crabs (family Majidae) , stone crabs (Menippe mercenaria) , and spiny lobster. Those fish species observe Inc uded porgies (Calamus sp . ) , snapper (Lutjanus sp . ) , grunts (Haemulon sp . ) , mojarra (species unknown) and cowfish (Acanthostracion quadricornis) . - The benthic vegetative cover over the proposed dredge area was esti- mated at between 50 to 75 percent. Algaes were the dominant vegetation although occasional patches of turtlegrass were found where sediments were deep enough for their support. Those species of red algae identified included Lia ora farinosa, Gracilaria ve-rrucosa, Eucheuma isiforme , Dasya pe ice lata, Laurencia sp . , Acanthophora sp. , and coralline algaes (Lithothamnion sp . ) . Brown algaes included Dictyota sp . and Padina sp . Green algaes included Penicillus sp. , calcareous algaes (Halimeda sp . ) , Caulerpa sp. , Udotea sp. and Dasycladus sp . The water depth over the proposed 800 foot long dredge area dropped from approximately -4 feet MLW to approximately -6 . 5 feet MLW. Deeper depths are found, in general , to the west of the proposed dredge alignment, although they also shallow up near the existing access channel . This area is commercially fished for lobster and occasionally, although on a more recreational basis , for stone crabs . The area in general provides excellent recreational diving and sport t -,. • TURTLE KRAALS , LTD. #44-42081-5E Monroe County - Marathon Shores Page Five fishing. It provides productive nursery and seasonal feeding areas for a variety of large marine forms and habitat sub- strate for a myriad of smaller life forms essential in forming the base of the marine food chain. This food chain is essential for the economy and livelihood of South Florida and, - particularly, the Florida Keys , where recreation is dependent in great part upon the well-being of the marine community. D. The primary impact of concern from the proposed project is the direct elimination by dredging of a 48 ,000 square foot natural marine habitat and its associated productive plant and animal communities . The biological diversity of the present marine population is anticipated to be reduced far below existing levels and well below the levels required by state water quality standards (reduction in biological integrity to less than 75 percent of background levels) . Due to the excellent flushing found in the basin, the proposed docks and their anticipated boat usage should not cause signi- ficant water quality degradation. Due to the impracticality of turbidity controls in the basin, some short term turbidity problems are expected during piling and mooring placement . Similar, more extensive , turbidity problems sould be expected during the excavation of the access channel. 4. • w.'.. ..-<:.,R _i. -•41. 4..?..... A ,. TURTLE KRAALS , LTD.. #44-42081-5E. : :.. Monroe County: =.,Marathon -Shores Page Six E.'- It is suggested that the application be modified to exclude any additional dredging of the 'existing' •access channel. An additional one to two feet of depth ,could. be obtained by widening the existing circulation cut leading- to Vaca Cut. This would have far less ;.long ..term biological impact (some mangrove wetland and a small amount of submerged bottom would be adversely impacted, although, judging from existing .cond tions in the circulation cut, regrowth of a viable marine .community could ;be expected) The major concern with an access' channel on this' side is the extreme currents and the consequential navigational hazzard it would impose. 'A modification`of:'this sort would have to be re- appraised from this standpoint.. JOH A. MEY R, ENV. S E II DA : Dec: 4 23, 1981 READ: .!/ I, _ D . G EN BeV •
