Resolution 287-1979 RESOLUTION if! 287-1979 v.7HEREAS, the BOARD OF COUNTY COMMISSIONER.S of MONROE County, FLORIDA, has received an application from Stephen Schuster to construct: 60 l.f. of riprap (35 cy) seawall and backfill with about 70 c.y. of clean marl fill on an open water shoreline. This seawall will be placed about 15' waterward of MITnv and will connect with, and be in line with, an existing riprap seawall immediately to the north. Materials and equipment will be delivered to the site over existing upland roads. Riprap will be placed and fill will be spread by backhoe. The project site is located on the east side of Little Torch Key within a residential community known as Jolly Roger Estates. This is a development with inland dead-end finger canals and a peripheral channel along the open-water shoreline. To the north of the area is U.S. #1 and additional residential shoreline development north of U.S. #1. Uplands within the general area of development are essentially all artificially created by the excavation of the canal systems. To the west and south of Jolly Roger Estates are natural mangrove wetlands and shoreline fringes. Development presently in this subdivision is about 30%. Pine Channel is tidal between the back country of Florida Bay to the north and eventually the Florida Straits to the south. Depths are from about -3 to -10' MLW and are productive seagrass or hard bottom-algae-sponge communities. A number of residents along this shoreline and peripheral channel have received permits and recovered eroded shoreline in a manner similar to this proposed project. Uplands at this site are filled and presently contain only Australian pines (Gasuarina) and various grasses and weeds. The shoreline has experienced severe erosion due to its orientation and exposure and presently the eroded embankment is about 20' landward of the peripheral channel cut. The watenvard edge of the existing shoreline is vegetated with scattered pioneering buttonwoods (Gonocarpus erectus). bay cedar (Suriana), sea ox-eye (Borrichia) and saltwort (Sesuvium). The intertidal zone is eroded, well-sorted rock rubble, about 10' wide and is essentially unvegetated. Present below MLW along the slope are the benthic algae Batophora and Laurencia and patches of turtle grass (Thalassia testudinum) where adequate sediments exist. Near the edge of the slope and the channel cut are denser patches of turtle grass. The placement of this riprap seawall in a line with the riprap wall on the adjacent lot will allow the applicant to recover eroded property without creating an additional shoreline discontinuity or impacting productive baybottom. Only a small area of benthic vegetation will be filled by the placement of this wall as proposed. Observation of the existing adjacent wall indicates that seagrasses immediately waterward of the riprap are not adversely impacted over time by the subtidal placement of the riprap. Eventually this entire shoreline v7ill probably be riprapped or seawalled in a similar manner although most of the work performed to date is farther to the south along this shoreline. BE IT FURTHER RESOLVED, by the BOARD OF COUNTY COMMISSIONERS of MONROE County, FLORIDA, that said Board hereby given its approval for the construction of the above mentioned project. u- \2-11 'APP..ROVIiD oN__. - ~... iL " l.'F .....
