Resolution 242-1981 _.. RESOLUTlmJ ~o. 242-1931 t-vFEREAS, the BOARD OF COUNTY CmlMISS lONERS OF ~1001ROE COUNTY, FLORIDA, has received an application from M,K. Al-Chokhachy and WHEREAS, in compliance with State Statute, it is necessary as part of the permittins procedure to read the following Biological Assessment into the Record, as follows: The Applicant proposed to construct a dock and revetment along his Duck Key (Center Island) property shoreline. The proposed dock struc- ture will consist of a 30 ft. wide (parallel to shoreline) by 15 ft. long predominantly "upland platform with a 4 ft. wide by 40 ft. long waterward arm extending from said platform's approximate middle. This dock structure will be situated on the property's northeastern corner, constructed of wooden decking materials, elevated on concrete support pilin0s (1+ ft. above the water surface, MHW) and equipped with two boat mooring pilings on its eastward side (13+ ft. from dock extension arm and 30+ ft. apart). The proposed revetment structure will be constructed of upspecified-size, Key Largo limestone boulder riprap materials. It will entail the deposition of 40+ cu. yds. of said rip- rap materials (10+ c.y. waterward of MHW; 30+ c~y. landward of MHW) along the entire 75 ft. property shoreline between the +1.0 ft. and -2.5 ft. (MSL) elevations and upon an existing rip rap revetment which has subsided considerably since its original construction. The appli- cant ~tates that all pilings and riprap materials will be placed from the applicant's adjacent shoreline property. Turbidity screens will be employed during construction activities, if required. The applicant's property is located along the northeaster Duck Key shoreline in middle Monroe County, Florida. At present, approximately 50 percent of Duck Key is developed with single family residences (S.F.R.'s) and various supportive facilities (ie, roadways, restau- rants, marinas, motels stores, recreational, etc.) Although some 10 percent; Duck Key shoreline areas have been artificially created, this particular shoreline area is situated in a natural corner of Tom's Harbor waters. Tom's Harbor waters are Florida State Class III waters as defined in Section 17-3,081 (F.A.C.). The majority of the existing residences within this area are equipped with some type of shoreline bulkheading and/or boating access facilites. The applicants's property consists of an average-sized (0.26 acres) residential lot bordered to the west by an existing SFR, to the east by a similar undeveloped lot, to the south by Bimini Drive roadway and to the north by Tom's Harbor waters. The westerly adjacent S.F.R. property is totally cleared, filled with pea gravel and landscaped with palms, seagrapes, bay cedar and assorted trypical exotics. It is also equipped with concrete shoreline seawall, dock and boat launching ramp facilities. Undeveloped upland property areas (both the applicant's and the easterly adjacent properties) have all been previously cleared, filled and are presently vegetated with isolated palms, Casurina spp, pines and secondary growths of various pioneer shrubs and grasses. Undeveloped natural shoreline areas have all been previously bulkheaded by a vary- ing-sized riprap revetment which is presently in various staqes of dis- repair. The proposed project area consists of the applicant's property shore- line areas and adjacent submerged lands. The applicant's property shoreline areas are presently bounded by a 25+ ft. wide transitional area dominated by buttonwood (Conocar~us erectus) and sea purslane (Sesuviu~ spp.) growths. Much or this area is presently disturbed by miscellaneous fill material deposits, construction rubble and land clearing debris, The property shoreline proper contains an old rip rap revetment which is presently in various stage of disrepair. MediuD heavy detrital accumulations were observed throughout this shoreline area both within said revetment and upon adjacent submerged lanes, Inshore submerqent areas (to 10+ ft from the existing shoreline) are presently disturbed both by the-aforementioned detrital accumulations and a relatively large amount of displaced, small diameter, riprap waterials. Inshore vegetation consists primarily of representative species of all algae types (especially greens). Inshore fauna observed included hermit crabs, Calinectes spp. crabs, sea hares and unidentified juvenile fish. Offshore submergent areas (beyond 20+ ft. from the existinq shoreline) may be characterized as shallow, of excellent quality and vegetated by varying-sized lush Thalassia spp. seagrass beds interspersed with firm, open, sandy/shell bottom areas. Offshore fauna observed included Siderastrea spp. hard corals, sponges and several locally common species of fish (needlefish, grunts, mojarra and pinfish) . Water depth in this increased gradually with increasing distance from the existing shoreline to a maximum measured depth within the project area of 3+ ft (MLW). Negative environmental impacts may be expected to occur from this pro- ject over both the short and long time periods. Short-terms or con- struction-related impacts will result primarily from the removal and loss of an unspecified amount of transitional and littoral vegetation presently growing within the proposed dock platform and revetment place- ment areas. Additional short-term impacts may be expected from turbi- dity raiseG during dock piling placement activities. Moreover, due to the s~allow water depths within this area such siltation impacts may be eXtended over the longer time period ,as a result of boat motor "prop scouring" impacts. ,I Longer term impacts may be expected both from said dock's "shadowing effect" upon adjacent seagrass beds and from hydrocarbon discharges into state waters from boat motor operation and maintenance procedures. However, both the limited size (160+ sq. ft. over-water surface area) and proposed use (ie, single residence) of said,dock facility suggest that neither of these latter two projected impacts will prove signifi- cant in this instance. Beneficial project impacts are anticipated from the expected increases in shoreline stability and littoral habitat area resulting from the proposed riprap revetment structure. 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 COIT~issioners of Monroe County, Florida, 11th August 81 this day of , 19 at a regularly scheduled meeting.

K .. 11'44-41816- SE Monroe County - Duck Key Page Two '. A. The applicant proposes to construct a dock and revetment along his Duck Key (Center Island) property shoreline. The proposed dock structure will consist of a 30 ft. \vide (parallel to shoreline) by IS ft. long predominantly "upland" platform with a 4 ft, wide by 40 ft. long waterward arm extending from said platform's approximate middle. This dock structure will be situated Qn the property's northeastern corner, constructed of wooden decking lIlaterials, elevated on concrete support pilings (Ii: ft. above the 'water surface; Mm~) and equipped with two boat mooring pilin~s on its eastward side (13+ ft. from dock extension arm and 30+ ft. apart), The proposed-revetment structure will be constructed of unspecified-size, Key Largo linestone boulder riprap materials. It will entail the deposition of 40+ cu. yds. of said riprap ma terials (10+ c. y, ,va terward 0 f t-mw; 30+ c. y. landward of HHU) along the entIre 75 ft. property shoreli~e between the +1.0 ft. and -2.5 ft. 01SL) elevations and upon an. existing riprap revet- ment which has subsided considerably since its original construc- tion. The applicant states that all pilings and riprap materials will be placed from thE: applicant's adjacent shoreline property. Turbidi ty screens wi:'1 ',T". - oyed during- construction activities, if required. B. The applicant's property is located along the northeastern Du~k Key shoreline in middle Honroe County, Fl~lrida. At present, approximately 50 percent of Duck Key is developed with single family residences (S.F.R. 's) and various supportive facilities (ie, roadways, restaurants, marin:'.s, motels, stores, recreational, etc.). Although some (10 percen~Duck Key shoreline areas have been artificially created, this particular shoreline area is situated in a natural corner of Tom's Harbor waters. Torn's Harbor waters are Florida State Class III waters as defined in Section 17-3,081 .(F.A.C.). The majority of the existing residences wi thin this area are equipped \,:1 th some. type of shoreline bulkheadi ng and/or boating arcess facilities, The: applicant's property consists of an average-sized (0.26 acres) residential lot bordered to the west by an existing SFR, to the east by a similar undeveloped.lot, to the south by Bimini Drive roaduay and to the nor th by Tom '~:; Harbor waters. The westerly adjacent S.F.R. property is totally cleared, filled with pea gravel and landscaped with palms, seagrapes, bay cedar ane assorted tropical exotics. It is also 'quipped with concrete shoreline seawall, dock and boat launching ramp facilities. Undeveloped upland property area~ (both ~he applicant's and the easterly adjacent properties) have all been previously cleared, filled and are presently vegetfltcd \vith isolated palms, Casurin~ sp~ . , AL-CHOKHACHY, H. K. i,~44- 41316- SE ~1onroe County - Duck Kjy Page Three C. pines and secondary growths of various pioneer shrubs and grasses. Undeveloped nctural shoreline areas have all been previously bulkheaded by a varying-sized rinrap revetment which is presently in various stages of disrepair. The proposed project area consists of the applicant's pro~~rty -shoreline areas and adjacent submerged lands. The applicant's - property shoreline areas are presently bounded by a L5+ ft, wide transitional area dominated by huttomvood (Conocarpus erectus) and sea purslane (Sesuvium spp.) grovJths. Huch-"of this area is presentl distrubed by miscellaneous fill material deposits, construction rubble and land clearing debris, The property shoreline proper contains an old riprap revetmpnt which is presently in various stage of disrepair. t'h::dium hE avy detxl. tal accumulations were observec:' throughout this shoreline area hoth within said revetment and upon adjacent submerged lands. .J Inshore submergent ,"reas (to 20+ ft. from t~e exi'1t.r~g Sf,cn.:-eli-,"'\ are presently disturbed both by"the aforementioned detri tal accumulations and a relatively large amount of displaced, small diameter, riprap materials. Inshore vegetation consists primarily of representative species of all algal types (especially greens). Inshore fauna observed included hermit crabs, Calinectes spY:'. crabs, sea hares ".:lei unidentified juvenile fish. Offshore sub- mergent areas (beyond 20+ ft. from the existing shoreline) may be characterized as shallow, of excellent quality and vegetated by varying-sized lush Thalassia spp. seagrass beds interspersed with firm, open, sandy/shell bottom areas. Offshore fauna observed included Siderastrea spp. hard corals, sponges and several locally co~non species of fish (needlefish, grunts, mojarra and pinfish). Water depth in this increased gradually with increasing distance from the existing shoreline to ;] maximum measured depth within the project area of 3~ ft. (HLH). D. :1egative environmental impacts may be expected to occur from this project over both the short and long time periods. Short-term or construction-related impacts will result primarily from the removal and loss of an unspecified'amount of transitional and littoral vegetation presentl~ growinG within the proposed dock platform and revetment placemvnt areas. Additional short-term impacts may be Jxpected [rom turbidity raised during dock pilin~ placement activities. Moreover. due to the shallow water depths \vithin this area such siltation impacts may be extended over the longer timl~ pf::riod as Cl result of boat motor "prop scouring" irnpac t s . ~.._-_. .~ , , AL-CHOKHACHY, M. K. =If .4-4l816-SE Honl"oe County -.Duck Key .". Page Four Longer term impacts may be expec ted both from said dock's "shadm'l- ing effect" upon adjacent seagrass beds and from hydrocarbon discharges into state waters from boat motor operation and mainte- nance procedures. However, both the limited size (160+ sq. ft, over-water surface area) and proposed use (ie, single residence) of said dock facility suggest ~hat neither of these latter two projected impacts will prove significant in this instance. Beneficial project impacts are anticipated from the expected in- creases in shorelin~ stability and littoral habitat area resulting from the proposed riprap revetment structure. f " AL-CHOKHACHY, M.

Under the provlslons of Chapters 253 and 403 (F.S.) and Sections 17-3 and 17-4 (F.A.C.), I hereby recoIT~end this application for Departmental approval. The following suggestions are offered for the applicant's consideration and/or as DepartT11ent permitting conditions: .... _1. Suggestion that applicant consider extending said dock struc- ture's waterward arm an additional 10-15 ft. in length. This would provide deeper water (+1+ ft.) at the dock's watenvard end thereby minimizing both bottom scouring and navigability risks. 2. Specification that all project construction activities be accomplished using only shallow draft vessels operating only during high tidal periods. This will,minimize bottom scouring of adjacent seagrass vegetation. 3. Specification that only shallow draft vessels be permitted use of said dock facility. 4. Specification that no fuel be stored upon said dock facility, ~() . ~,} . ER CR. .:0IzEN, II Date: Read: E1< I dvo
