Resolution 174-1979
RESOLUTION # 174-1979
WHEREAS, the BOARD OF COUNTY COMMISSIONERS, of MONROE County,
Florida, approved an application for Harold Miller to construct
225 feet of Seawall, and
lffiEREAS, the Department of Environmental Regulation pursuant
to Section 253.124, Florida Statutes, requires that before a State
Permit can be issued that a Biological Assessment made by DER be
read into the Minutes of the County Commission.
NOW, THEREFORE BE IT RESOLVED that the following Biological
Assessment be read into the Minutes of the County Commission and
approved by that same body.
Applicant proposes to construct a seawall along plotted
property line, which aries between 2 to 5 feet waterward of e~sting
MHW line. Seawall will be constructed of short section of square
concrete piles, tied landward, at 10' intervals, with sections of
concrete piles used as "rakers", except at corner where larger rakers
will be used for the curve. Area behind the seawall will be filled
with 241 c.y. of clean sand and marl delivered from upland. Large
rip-rap will be placed at waterward toe of seawall. A concrete cap
is proposed over the seawall.
This is a manmade, water oriented development with canals and the
upland is mostly fill marl, which has eroded unevenly along the
waterward line of the unprotected lots. The developed homesites
have seawalls or boulder rip-rap at waters edge, with some type of
boat mooring. The vegetation on the developed lots is ornamental,
on the undeveloped lots, pioneer. This area is approximately 60%
developed.
The bay bottom (shelf) in the area as the seawall is marl silt with
1-2% small stones and empty gastropod shells. Waterward of the toe
of the seawall, a sparse growth of Tha1assia, tiny clumps of
Batophora spp. and Haodule wrightii (Cuban shoa1weed) exist. In
the construction zone, a white mangrove (Laguncularia racemosa)
and two black mangroves (Avicennia germinans) are growing. One red
mangrove (Rhizophora mangle) is growing waterward of site. On the
eroded face and the edge of the lot, Borrichia spp., Sesuvium sp.
grasses, sandspurs, spanish needle, and Brazilian pepper have become
established.
A hermit crab and two(2) transitory snappers were observed in the
project area. Samples of the marl bottom, in project site, contained
no macroscopically visible organisms.
The impact of this project will be the reduction of erosion from
this corner plot and the increase in habitat among the boulder
rip-rap. The established black and white mangroves, growing
precariously on the edge of the lot may not be able to survive the
placement of fill.
