Resolution 072-1982 HESOLUTlON :f\TO. 72 -1982 "JHEPEAS, the BOARJ1 OF COUNTY Cmn~ISSIONERS OF MONROE COUNTY, VLORlDA, has received an application from lnst. of Delphinid Research LTD. , and ~'lHEREAS, in compliance with State:-:!tatute , it is necessary as part of the permitting procedrue to read the following Biological Assessment into the Record, as follows: The applicant proposes the stabilization and development of a canal shoreline and an open water shoFeline bordering a perimeter channel to provide private boat mooring and shoreline protection. More specifically, 000 lineal feet of concrete walkway will be constructed along the canal shoreline, 180 lineal feet of riprap (12 feet wide) will be deposited along the open water shoreline, with a 7 foot wide dock constructed adjacent to and slightly waterward of the riprap and an additional 120 lineal feet of dock will be constructed along the offshore perimeter channel dropoff,' so as to create an open water U-shaped basin. Additionally, a 20' x 40' boat ramp will be excavated near the terminal end of the above mentioned canal. Excavation will be by backhoe and hand. The rinrap will be placed on a 3.1 s lope out to the ~~L"T line on the open water shoreline. The canal shoreline will be cut back about 10 feet with a backhoe and lined with filter cloth down to MSL. ~iprap would then be placed over the filter cloth with a concrete walk constructed out to the edge of the canal drop. The top of this walk would be slightly above HHW with concrete stairs laid on top of the riprap leading to the top of the em- bankment. The boat ramp would involve the removal of 65 cubic yards, most of vlhich would be above I~H~'l, although the waterward 17 feet would be excavated below ~mT\T. The sides of the ramp would be riprapned on a 4.1 slope. A total of ?40 cubic yards of riprap would be deposited for the entire project, of which, 200 would be landward of ~~HW. Of this total, 115 cubic yards would be placed along the open water shore- line. Pilings for the dock will be augered from a barge. Turbidity screens will be utilized where necessary. The project site is located on the western shoreline of Big Pine Key bordering Pine Channel, which connects the Gulf with the Atlantic in the Lower Keys. U.S. #1 is located immediately to the south of this site and a new bridge is presently under construction here. To the north is Pine Channel Estates Subcivision, a canal oriented residential community. The canal and offshore perimeter channel bordering the applicant's property are, in fact, a part of this subdivision canal system. The applicant's upland has been zoned for business by the county. Pine Channel is moderately shallow, with excellent water quality and a predominance of seagrasses over its bottom. Resolution Institute of Delphinid Research, LTD. Page Two The canal and perimeter channel are extremely deep, although water quality is better than might be expected for a dead end system due to an optimal orientation to dominant wind directions. The applicant's property is primarily of an upland nature, drop- ping sharply at the erosion line to form a 10-15 foot wide open- water littoral shelf (0.5 feet wide along the canal), which then drops into the channel or canal depths. The open water littoral shelf presently supports a patchy and somewhat stunted growth of red mangroves (Rhizophora m~ngle). The substrate along this shelf is somewhat prohibitive to mangrove growth due to its hard, rock limestone rubble characteristic. Nearly all of the mangroves observed here were found in betwe8n MV~ and ~'m\T. Those species of organisms observed below MLW included green algaes (Batophora sp. and Penicillus sp.), calcareolls a 1 gaes (Halimeda sp.), red algaeR (Acanthophora sp.), anem0nes (Bartholomea sp,), starfish (Echinaster sp.), barracud~ (Sphraena barracuda), schoolmaster snapper (Lutjanus griseus), pinfish (Lagodon shomboides), jack crevalle (Caranx hippos), and grunts (Haemulon sp.). The canal shoreline is lined wjth Australian Pines (Casuarina equisitifolia). The narrow submergent shelf here displays some green algaes and very scattered sea grasses (Syringoduim filiformis). Both the channel and the canal are boxcut dropping to unidentifiable depths. The outside or western edge of the perimeter channel, where dock construction is to take place, supports a lush variety of turtle- grass (Thallassia testudinum), Cuban shoalweed (Halodule wrightii), and numerous algaes before dropping to greater depths. Adverse impacts are expected to be minimal for this project, al- though some concern exists over the amount of dock space and the potential for water quality degradation from boat usage. Circula- tion is good in this area and it is felt that any potential pollu- tants would have a low residence time. A small number of small mangroves will be lost along the open water shoreline, however, the riprap put in its place should add stabilization to the shoreline and provide a small amount of intertidal habitat. BE IT RESOLVED BY THE BOARD OF COUNTY COMMISSIONERS OF MONROE COUNTY, FLOIRDA, 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 Commissiqners of Monroe County, Florida, this 23rd day of February , 19 82 at a regularly scheduled meeting. 11'1 A.. ~. 0ffit:tI BOARD OF COUNTY COMMISSIONERS OF ::NR?;'~ED~ 1f1 RALPH W.

INTRODUCTION This application is to be reviewed by the Board of County Co~missioners in accordance with Chapter 19-111 (a) (5) of the Monroe County Code. DISCUSSION The applicant proposes the following activities on the subject property. 1. Construct a 900 linear foot long by 5 foot wide walkway along the man-made canal bordering the property on the north. A 10 ft. ~ide area will be excavated from the landward edge of the canal down to the caprock. Rip- rap and filter fabric will be placed along the slope of , this excavation for stahilization purposes. Steps will be constructed from the upland to the aforementioned concrete walkway. The walkway will be placed on the ex- posed caprock. Rip-rap will also be placed along 180 linear feet of Pine Channel shoreline. The total amount of boulders required will be 240 c.y. (200 c.y. of which will be placed above Hl-IW) . <) '-J . A boat ramp (40 ft long by 20 ft. wide) will be constructed on the canal approximately 150 ft. from the canal opening to Pine Channel. ~he boat ramp will result in the removal of 65 c.y. of material including 17 c.y. below MHW. 3. A wooden L-shaped dock measuring 105 ft. parallel to the shorelineJslightly waterward of the rip-rap) and 75 ft. perpendicular to the shoreline will be constructed. The dock will be 7 ft. wide. 4. Also proposed is a rental jsales building to be located on Lhe property. Henry F. Weinkam, Director Institute of Delphinid Research, Ltd.

Dear Lynn: I wish to inform you that the seawall proposed along the canal can be permitted at this time, but the dock in Pine Channel cannot. The reason for this is that Monroe County considers such structures accessory and as such cannot be built until such time as a principle building or structure is constructed, (Monroe County Code Chapter 19-132.1). Also, the future plans for the upland may constitute a major development project. You may wish to talk with Mr. Henry Weinkam, Director of Building, Planning and Zoning, aboutlthis project at your earliest convenience.

The applicant proposes the stabilization and developmeht'of a canal shoreline and an open water shoreline bordering a perimeter channel to provide privatebo~t mooring and shcreline protection. More specifically. 900 lineal feet of concrete walkway will be constructed along the canal shoreline, 180 lineal feet of riprap (12 feet wide) will be deposited along the open water shoreline, wi th a 7 foot wide dock .con::;tructed adj acent to _ and"s,light1y waterward of the riprap and an additionaL 120 lineal feet of dock will be constructed along the offshore perimeter channel dropoff. so as to create an open,water U-shapped basin. Additionally, a 20' x 40' boat ramp will be excavated near the terminal end of the above mentioned canal. Excavation will be by backhoe and hand. ' The riprap will be placed on a 3:1 slope out to the MLW line on the open water shoreline. The canal shoreline will be cut back about 10 feet with a backhoe and lined with filter cloth down to MSL. Riprap would then be placed over the filter cloth w~th a concrete walk constructed .out to the edge of the canal drop. The top of this walk would be slightly above MHW with concrete stairs laid on top of the riprap leading to the top ...of the em- bankmen t . The boat ramp would involve the removal of 65 cubic yards, most of which would be above MHW, although" the waterward 17 feet would be excavated below MHW. The sides of the ramp would be riprapped on a 4:1 slope. A total of 240 cubic yards of riprap would be deposited for the entire project, of which. 200 would be landward of MEW. Of this total,. 115 cubic yards would be placed along the open water shore- line. Pilings for the dock will be augered from a barge~ Turbidity_ screens will be utilized where necessary. B. The project site is located on the western shoreline of Big Pine Key bordering Pine Channel, which connects the Gulf with the Atlantic in the Lower Keys. U.S. #1 is located immediately to the south of this site and a new bridge is presently under construction here. To the north is Pine Channel Estates Subdivision, a canal oriented residential community. The canal and offshore perimeter channel bordering the applicant's property are, in fact. a part of this subdivision canal system. The applicant's upland has been INSTITUTE OF DELPHilED IU:SE/'..R.CH, LID ~ {f44-45788-5E Monroe County' - Big Pine Key Page Three zoned for business by the county. .' Pine Channel is noderately shallow, with excellent water quality and a predominance of seagrasses over its bottom. The canal and perimeter channel are extremely deep, although water quality is better than might be expected for a dead end system due to an optimal orientation to dominant wind directions. C. The applicant's property is primarily of an upland nature, drop- ping sharply at the erosion line to form a 10-15 foot wide open- water littoral shelf (0.5 feet wide along the canal), which then drops into the channel or canal depths. The open water littoral shelf presently._-support.s a patchy and somewhat stunted grGlth of red mangroves"(Rhizophora mangle). The substrate along this shelf is somewhat prohibitive to mangrove growth due to its hard, rock limestone rubble characteristic. Nearly all of the mangroves observed here were found in between MLW and MHW. Those species of organisms ,observed below MLW inc~uded green algaes (Bato1hora sp and Penicillus sp.), calcareous algaes (Halimedasp.), red a gaes (Acanthophorasp.), anemones (Bartholomea sp.), starfish (Echinaster sp.), barracuda (?~Faena barracuda), schoolmaster snapper' (Lutjanus ~riseus), linfish. I,Lagodon rhomboides), jack crevalle 1Caranx h1PPos), an grunts (Haemu1on sp.). The canal shoreline is lined with Australian Pines (Casuarina equisitifolia). The narrow submergent shelf here displays some green algaes and very scattered sea grasses -CSyx'itig6dliiIIifiliformis). . Both the channel and the canal are boxcut dropping to unidentifiable depths. The outside or western edge of the perimeter channel, where dock construction is to take place, supports a lush variety of turtle- grass (Tha1assia testudinum), Cuban shoalweed (Ha1odule wrightii), and numerous a1gaes before dropping to greater depths. - D. Adverse impacts are expected to be minimal for this project, al- though some concern exists over the amount of dock space and the potential for water quality degradation from boat usage. Circula- tion is good in this area and it is felt that any potential pollu- tants would have a lo\v residence time.
