WHEREAS, the BOARD OF COUNTY COM}1ISSIONERS OF MONROE COUNTY, FLORIDA,
has received an application from DAVID S. ARMBRUSTER, 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 the placement of boulder riprap along a residential
shoreline between MLW and }ffiW to prevent erosion and debris collection. This
riprap zone will be 6-7 feet wide and restored with mangroves. In all, 75 cubic
yards of riprap will be deposited below MHW for a length of approximately 171 ft.
The site is on the eastern side of Cudjoe Key, opposite Cudjoe Bay and
remotely adjacent to Kemp Channel. This shoreline has been partially filled and
as a result, is eroded with a limestone rubble composition. It supports a
secondary, athough in some places, a substantial, mangrove fringe. A network of
inland canals and peripheral channels have been dredged throughout the entire area.
Although this area has not been substantially developed (less than 1 percent
development), it is platted and building is anticipated to a degree similar to
the residential canal community directly to the north. It is also anticipated
that bulkheads, basins and docks will be desired in a residential area such as
this, especially along the open water shoreline where deep water access is found
10-15 feet offshore. This access (peripheral channel) is shallow (approximately
4-5 ft. (MSL) and narrow (15-20 ft. wide). Between this peripheral channel and
the shoreline is a shallow littoral shelf that supports lush algae and grass
beds below MLW.
The applicant's shoreline proposed for riprap placement faces south to
open water. The offshore benthos drops gradually, but for the most part, maintains
1-5 foot depths until dropping off into Hawk Channel south of Loggerhead Key.
This offshore area supports vast seagrass beds and sponge-dominated benthic
communities. The shallow peripheral channel just offshore from the applicant's
property has revegetated with turtle grass (Thalassia testudinum) and cuban
shoalweed (Halodule wrightii). Sediments here are soft calcareous sands and
limestone accounting for the gentle side slopes of this peripheral channel.
Inshore from this channel, the submergent shelf referred to in 2nd paragraph
is found. This shelf supports a healthy growth of turtle grass, shoalweed and
Batophora sp. Some pioneering red mangrove (Rhizophora mangle) seedlings are
found scattered below MLW. Above the MLW line and extending to MEW, the substrate
is loose limestone rubble supporting green filamentous algaes. This area may have
originally supported red and black (Avicennia germinans) mangroves, based upon
adjacent lot observations, but presently contains only two large black mangroves
and several seedlings of both species.
Riprap has already been placed along the intertidal area for the entire
length of the applicant's property. This riprap is near MEW just below the wrack
line, which is heavy, due to wind orientation. This riprap was larger and more
recently placed on lot 7. Along this loose limestone rubble intertidal zone,
nerites and a single blue crab (Callinectes sapidus) were observed. M)ove the
wrack line, sea purslane (Sesuvium portulacastrum), was the dominant transition
species, although this transitions zone is narrow and in some places, non-existant.
The impact anticipated from this project should be minimal. This project
would seem to be the least environmentally damaging alternative to shoreline
stabilization. By stabilizing the shoreline, substrate and shelter for sessile
and mobile marine organisms will be formed. In the process, a suitable area for
mangrove repropagation will be lost, although some red mangroves may take hold
at the foot of the riprap.

Cudjoe Key. Zoning is RU-l.
PURPOSE:
This project is to be reviewed by the Board of County
Commissioners in accordance with Ordinance 13-1980.
DISCUSSION:
Applicant is applying for an after-the-fact permit to
construct a rip-rap seawall 171 ft. in length along his
Cudjoe Bay shoreline. Approximately 75 c.y. of rip-rap will
be placed waterward of MHW. Red mangroves will be planted
amongst the boulders to provide additional stability to the
seawall.
A listing of flora and fauna found here is presented in
the attached DER report.
REASON FOR PROJECT:
Shoreline protection from erosion.
EVALUATION:
This project will cause short term impacts by restricting
normal ebb and flow tides and so affect the existing inter-tidal
species community. In the long term, the rip-rap will provide
habitat for benthdcflora and rocky shoreline fauna.
RECOMMENDATIONS:

Th2 site is on the eastern side of Cudjop Key, opposite CcJjoe
Bay and remotely adj acent to Kemp Channel. This shoreline l-,03s
been partially filled and, as a result, is eroded with a lime-
stone rubble composition. It supports a secondary, although
in some places, a substantial, mangrove fringe. A network of
inland canals and peripheral channels have been dredg~d through-
out the entire area.
Although this area has not been substantially developed (less
th~n 1 percent development), it is platted and building is
anticipated to a degree similar to the residential canal
community directly to the north. It is also anticipated that
bulkheads, basins, and docks will be desired in a residential
area such as this, especially along the open water shoreline
where deep water access is found 10-15 feet offshore. This
access (peripheral channel) is shallow (approximately 4-5 ft.
MSL) and narrow (15-20 ft. wide). Between this peripheral
chanpe1 and the shoreline is a shallow littor-a1 shelf that
support slush 3lg,le and gr<1SS beds below ~/rLH.
The 3nplicant's shoreline proposed for riprap placement faces
south to open ~ater. The offshol"e benthos drops gradually, bu~
