Resolution 141-1981 r r'-'-~ RESOLUTION NO. 141 -1981 WHEREAS, the BOARD OF COUNTY COMMISSIONERS OF MONROE COUNTY, FLORIDA, has received an application from Frederick G. Pickles, 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 proposes to place rip rap below MHW along about 115 1.f. of open water shoreline, to recover eroded property and prevent further erosion. No estimates are given for the amount of riprap necessary. Approximately 80 c.y. of limerock would be excavated on the same shoreline landward of MHW in lieu of riprap to create a sloping beach area measuring about 40' x 40'. Materials will be placed by hand or backhoe and all equipment and materials can be transported to the site over existing uplands. The project site is located in a residential area created by the ex- cavation of peripheral channels and finger canals from wetlands and using fill for creation of uplands. Adjacent bay waters are shallow throughout and benthic habitats include hard bottom algae communities or seagrasses where adequate sediments exist. Orientation of the site shoreline is to the SW Residential development in the area is about 20~~ of available Pr0rerties.. The site shoreline is essentially unvegetated and consists of eroded rock boulders and rubble with MEW located about 8-12' landward of the irregular edge of the peripheral channel. Depths along the lower edge of this sloping shoreline are about -1.0 to -1.5 MLW and subtidal vegetation is limited to the algae Batophora on the larger rock rubble. Uplands are unvegetated limestone rubble and fill. Lack of subtidal vegetation may be the result of wave-wash along the eroding shoreline, creating unstable conditions in the subtidal zone. The excavation of a 40' x 40' beach area from this shoreline will create a sizable discontinuity with the resultant effect of altering and reducing near shore current patterns and creating a trap where suspended sediments and debris are able to settle out only to be resuspended by activity or wave-wash. The need along this type of artificial shoreline is to halt erosion allowing more stable conditions to develop and to keep as smooth and straight a shoreline as is possible to facilitate current flow. Wind- blown seagrasses are not as severe a problem here as in other areas but an excavated area will trap any floating debris as do the local deadend canals with the resulting buildup of undesirable sediments on the bottom. Placement of riprap as designed out to the edge of the peripheral channel will result in the elimination of a shallow subtidal zone (4-6' wide) landward of the edgeof the peripheral channel. If the upper shoreline is stabilized the subtidal area has the potential to become vegetated by algae and seagrasses providing a valuable habitat and source of organics to the system. Nearshore zones are important to a variety of small fishes and invertebrates but have been virtually eliminated from these dredge and fill canal subdivisions. The cumrnulative effects of a number of excavation and fill projects along open water shorelines has to be considered from the standpoint of additional shoreline discontinuities and pockets and excessive loss of shallow water habitats.

Based on biological considera~ions and in accordance with Chapters 17-3.011, 17-3.051 and 17-4.29 FAC and Chapter 403.8 and 253 FS, I recommenJ denial of this project as proposed. Modification to the proposed project that "lOuld allow a recom- mendation of approval from this writer include eliminating any plans for excavation and placing the riprap line along MLW instead of the edge of the peripheral channel. Riprap would therefore be placed about 6' back from the edge and would tie to the existing seawall along the canal shoreline. Backfill would probably be desired behind the riprap due to the eroded area landward of the riprap and some plans should be made for retention of this backfill. An opening in the riprap would allow access to the open waters, although a bottom type diffi- cult to walk on would be encountered. Backfill should be sloped 3tvay from the water to prevent unfiltered runoff from entering state waters. Date: 1/ J: KRGEt~i~~~~~/SPEC. II April 10, 1980 CURTIS Read: GLEN HOE CK/dvo
