RESOLUTION 1ft 89-1980
WHEREAS, the BOARD OF COUNTY COMMISSIONERS of MONROE County,
Florida, has received an application from George and Susan Schmohl,
to cons truct:
160 l.f. of concrete seawall below MHW along an open-water
shoreline. This would be in line with and connect to an existing
seawall to the north and about 150 c.y. of back fill would be placed
waterward of MHW and about 150 c. y. landward of MHW. Equipment and
materials can be transported to the site over existing uplands and the
seawall will be constructed before backfill is placed.
The project site is located in a residential subdivision created by
the excavation of numerous dead end finger canals and a peripheral
channel. Orientation of the finger canals and shoreline is to the S.W.
Upland usage is strictly residential and development is about 10-15%
of available property. The adjacent bay is very shallow (-1' to
-3' MLW) except for the adjacent artificial peripheral channel and con-
tains primarily hard bottom algae communities. Seagrasses occur where
adequate sediments exist.
This site is on a corner lot formed by open-water and a finger canal
dug inland from the immediately adjacent peripheral channel. The
open-water shoreline is sloping, rock rubble eroded back about 15-20
from the edge of the channel and MHW is presently 10-15' landward of
the channel edge. Uplands are old fill with essentially no vegetation
and intertidal vegetation is limited to the algae Batophora. MLW to
the irregular channel edge measures about 5-8' and this subtidal area
contains enough sediments to support growths of short bladed turtle
grass (Thallassia testudinum) but in rather sparse densities. The
algae Batophora and Chondria are also present on rock rubble in this
subtidal zone. Increased growth of turtle grass here is probably
limited and will continue to be by the shallowness of this nearshore
zone and the lack of suitable sediments due to periodic wave-wash
and sorting out and removal of finer particles.
The irregular, eroded nature of the channel edge will make it impossible
to place the seawall in a continuous straight line with the adjacent
seawall and immediately landward of the channel edge as diagrammed.
Across the finger canal from the site is an open-water riprap shore-
line with the riprap recessed only several feet from the channel edge.
This project as proposed will form a continuous shoreline with the
adjacent seawall but is ill-designed due to the irregular nature of
the channel edge in this area. Ideally the seawall would tie in to the
adjacent wall and then be recessed about 4-5' landward thereby avoiding
this irregular edge and leaving a portion of the vegetated subtidal
area which is valuable as habitat and food production to local marine
organisms. The canal shoreline is exempt from permit requirements.
Inaccuracies exist in the application related to the location of M~l
and MLW on the sloping shoreline and distances involved. The adjacent
concrete bulkhead is recessed about 2-4' from the channel edge not
immediately adjacent is the x-section for the proposed wall is
represented.
BE IT FURTHER RESOLVED, by the Board of County Commissioners
of Monroe County, Florida, that said Board hereby given its approval
for for the construction of the above mentioned project.
