Resolution 267-1979u
RESOLUTION # 267-1979
WHEREAS, the BOARD OF COUNTY COMMISSIONERS of MONROE County,
Florida, has received an application from George Bohland, to
construct:
A concrete seawall along an open -water (106 l.f.) and canal
(151 l.f.) eroded shoreline, below MHW at the edge of a peripheral
channel and canal cut. Distance below MHW ranges up to about 10'.
About 400 cubic yards of backfill will be necessary to bring the
bulkheaded area to grade and the applicant estimates about 80 cubic
yards will be placed below MHW. This latter figure is probably an
underestimation and miscalculation. The seawall will connect to an
existing bulkhead on the canal side.
The bulkhead will be a concrete block wall built from a concrete
footer with a 4' wide concrete walkway on top. Equipment and materials
will be transported to the site over existing uplands.
The project area is a residendial subdivision on the west side of
Big Pine Key that contains 8 finger canals on an east -west orientation.
These canals are excessively deep, up to about 2100' in length,
contributed fill to upland development, and connect to a peripheral
channel that runs along this shoreline of Pine Channel. The
Subdivision is currently about 20% developed. To the north of this
area is natural mangrove shoreline for some distance and to the south
is U.S. #1 and across U.S. 1 is a combination of developed and natural
shorelines. Depths in Pine Channel immediately across the peripheral
channel are about -1 to -2' MLW and consist of rocky substrate with
their sediment layers, this slopes into the main part of Pine Channel
to the west where depths are generally -4 to -6' MLW and benthic
communities range from seagrasses where sediments are adequate to hard
bottom algae --soft coral -sponge communities.
The specific site is an old fill lot that affronts open -water and a
residential canal. Both shorelines have eroded back a considerable
distance and were also excavated at some time in the past for some
unknown reason according to the applicant. Some of the fill is still
piled on the upland portion of the lot. Shorelines are eroded back
up to about 12 to 14' from the artificial cuts and MHW is up to about
10' landward of the cuts. Vegetation is limited in this intertidal
zone to the algae Batophora and on the uplands to grasses and weeds.
There are bulkheaded immediately across the canal on the corner lot,
immediately up the canal on the same shore and across the road right-
of-way to the south. ,
The canals are about 40' wide and the channel about 50'. Depths
are unknown but are excessive (probably 15'+) and benthic communities
are believed to be limited by these depths and conditions.
This project will have no adverse impact on local biological resources
and will eliminate additional erosion to 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.
RESOLVED this 20th
Regularly scheduled Meeting.
