RESOLUTION NO. 274
-1982
WHEREAS, the BOARD OF COUNTY COMMISSIONERS OF MONRE COUNTY,
FLORIDA, has received an application from Marathon Project
Partnership , 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 to protect the shoreline of his property
from erosion. The goals will be achieved by building a 100 foot
long vertical concrete seawall at the approximate mean sea level
(MSL) line on the shore of the applicant's property. Backfill
for the seawall will consist of 36+ cu. yards of material water-
ward of MHW and 45+ cu. yards landward of MHW in the waters of the
state. An estimated 500+ sq. ft. (0.012 A) of emergent (mangrove)
wetland and 1000+ sq. ft~ (0.023 A) of transitional wetland will
be filled. Approximately 45 cu. yds of riprap will be placed
at the toe of the seawall.
Construction of the seawall will be accomplished from the adjacent
uplands. All materials and equipment will be brought to the site
over upland routes. Turbidity curtains will be used to maintain
water quality.
The project site is located in the Sombrero area of Marathon.
Nearby development consists of single and multi-family homes as
well as a golf course. To the northwest of the project site is the
Lady Alexander Condominiums and to the southeast is Sombrero
Boulevard, beyond which is a golf course. An undeveloped lot,
which the applicant owns and has proposed a similar project on
(file No. 440525615) adjoins the site's northeast side. Beyond the
applicant's adjacent lot is a small condominium. Boot Key Harbor,
which is 1500+ ft. wide in the project area and designated as Class
III waters (Chapter 17-3.081, Florida Administrative Code) lies to
the northwest of the project site.
The project site is part of a 3000+ ft. long shoreline running
from the south side of Boot Key Harbor. Existing development along
this shoreline consists of a variety of seawalls, revetments, docks,
boat ramps and dredge areas, several of which resemble the proposed
project closely. The land in this area was created approximately
25 years ago, by filling mangrove wetlands with material dredged
from Boot Key Harbor.
The project site is located along the waterward side of the
applicant's property. The property consists of a single 100~ ft.
square (0.25 A) residential lot. As previously stated the lot was
created approximately 25 years ago by filling wetlands adjacent to
Boot Key Harbor. The fill material was dredged from the harbor
and consists primarily of marl, with some shell hash mixed in.
Until recently the majority of the applicant's lot w~s vegetated
by various upland pioneer grasses and trees, especially Australian
pines. In the recent past, the lot was cleared and the resulting
debris piled in its center.
The waterward edge of the lot has a low escarpment on it. The toe
of the escarpment represents the approximate MHW line. Previous to
the recent clearing a 10 to 15 foot wide area of transitional wet-
lands was located immediately landward of the top of the escarpment.
Resolution
Page Two
Vegetation in the transitional wetlands consisted of buttonwood
trees (Concarpus erecta) , sea daisy (Borrichia sp.), sea purslane
(Sesuvium portulacastrum) and salt grass (Distichlis spicata).
On the face of the escarpment and in a narrow area immediately
waterward of it, the remains of red mangrove (Rhizophora mangle),
black mangrove (Avicennia germinans) and white mangrove (Laguncularia
racemosa) trees are located. The vegetation in this area was also
removed during the recent scarification such that only the roots
and stumps remain. It should be noted that no Department author-
ization was sought or granted for clearing the wetlands.
Between the toe of the escarpment and the MLW line is a 10 to 15
foot wide area of moderately sloping beach. The substrate on the
beach is similar to that of the lot with the addition of a moderate
amount of shell hash which was apparently left on the shore after
erosion cut the escarpment into the beach. Waterward of the MLW
line the baybottom slopes downward more or less evenly until it
reaches a depth of 5 feet MLW at a distance of 30+ ft. waterward of
the MLW line. From the 5 foot MLW contour, the bottom slopes more
steeply downward to the harbor floor.
A fauna consisting of false ceriths (Batillaria minima), fuzzy
chiton (Acanthopleura granulata) , paper oysters (Isogonomon sp.)
and barnacles was found in the littoral zone of the site. Sub-
Ii ttoraly the near shore area is vegetated primarily by a mixture
of Cuban shoalweed (Diplanthera wrightee), and turtlegrass
(Thalassia testudinum). Frequent examples of Halimeda tuna,
Halimeda incrassata, Batophora sp., Penicillus sp., Udorea-sp.,
Aceturbularia sp., Caulerpa spp., Padina sp., Jania sp., Laurencia
sp. and unidentified algae were found throughout the proposed dredge
area. Faunal elements consists of Tegula fasciata, fly specked
cerith (Cerithium muscarum) , dwarf cerith (Cerithium lutosum), hawk
wing conch (Strombus raninus), moon snails (Natica sp.) hermit crabs,
grunt (Haemulon sp.) barracuda (Sphyraena sp.), stomatopods, tunicates,
sponges, star coral (Siderastrea readans) and lobsters (Panulirus
argus). In summary, the intertidal and shallow baybottom in the
project area is a very rich benthic marine biological association.
Construction of the seawall with associated backfill will permanently
eliminate the emergent and transitional wetlands along the project
site's shoreline. With the elimination of the wetlands their func-
tion as habitat, sources of primary production and upland runoff
filtration will also be eliminated. Placing riprap along the toe
of part of the seawall will tend to partially replace some of the
wetlands function as habitat.
Construction related activities will tend to result in elevated
levels of turbidity, dissolved organic compounds and particulate
organic compounds in the waters at and near the project site.
Proper use of turbidity curtains should be able to adequately control
these problems.
BE IT RESOLVED BY THE BOARD OF COUNTY COMMISSIONERS OF MONROE
COUNTY, FLORIDA, that the above Biological Assessment has been
read into the record and duly considered pursuant to Florida
Statute 253.124 by the Board of County Commissioners of Monroe
County, Florida, this 18thday of
October
, 19 82
at a regularly scheduled meeting.

A. The applicant proposes to protect the shoreline of his property
from erosion. Thc goals will be achievcd by building a 100 foot
long vertical concrete seawall at the approximate mcan sea level
(MSL) line on the shore of the applicant's property. Backfill
for the seawall will consist of 36+ cu. yards of material water-
w~rd of MHW and 45+ cu. yards landward o"r Mlflv in the waters of the
state. An estimat~d 500+ sq. ft. (0.012 ^) of emergent (mangrove)
wetland and 1000+ sq. ft~ (0.023 A) of transitional wetland will
be filled. Approximately 45 cu. yds. of riprap will be placed
at the toe of the seawall.
Construction of the seawall will be accomplished from the adjacent
uplands. All materials and equipment will be brought to the site
over upland routes. Turbidity curtains will be used to maintain
\water quality.
B. The project site is located in the Sombrero area of Marathon.
Nearby development consists .of~ single and multi-family homes as
well as a golf course. To the northwest of the project site is the
Lady Alexander Condominiums and to the southeast is Sombrero
Boulevard, beyond which is a golf course. An undeveloped lot,
which the applicant owns and has proposed a similar project on
(file no. 440525615) adjoins the site's northeast side. Beyond the
applicant's adjacent lot is a small condominium. Boot Key Harbor,
which is 1500+ ft. wide in the project area and designated as Class
III wqters (Cnapter 17-3.081, Florida Administrative Code) lies to
the northwest of the project site.
The project site is part of a 3000+ ft. long shoreline running
from the south side of Boot Key Harbor. Existing development along
this shoreline consists of a variety of seawalls, revetments, docks.
boat ramps and dredge areas, several of which resemble the proposed
project closely. The land in this area was created approximately
25 years ago, by filling mangrove wetlands with material dredged
from Boot Key Hsrbor.
C. The project site is located along the waterward side of the
appl ican t 's property. The prop erty cons is t s 0 f a sing Ie 100+ ft.
square (0.25 A) residential lot. As previously stated the lot was
created approximately 25 years ago by filling wetlands adjacent to
Boot Key Harbor. The fill material was dredged from the harbor
and consists primarily of ma..rl, with some shell hash mixed in.

Until recently the majority of the applicant's lot was vcgetated
by various upland pioncer grasses and trces, especially Australian
pines. In the recent past, tho lot was cleared and the resulting
debris piled in its center.
The waterward edge of the lot has a low escarpment on it. The toe
of the escarpment represents the approximate MHW line. Previous to
the recent clearing a 10 to IS foot wide area of transitional wet-
lands was locat~d immediately landward of the top of the escarpment.
Vegetation in the transitional wetlands consisted of buttonwood
trees (Concarpus erecta), sea daisy (Borrichia sp.), sea purslane
(Sesuvium portulacastrum) and salt grass (Distichlis spicata).
On the face of the escarpment and in a narrow area irnnediately
waterward of it, the remains of red mangrove (Rhizophora mangle),
,black mangrove (Avicennia germinans) and white mangrove (Laguncularia
racemosa) trees are located. The vegetation in this area was also
removed during the recent scarification such that only the roots
and stumps remain. It should be noted that no Departmental author-
ization was sought or granted for clearing the wetlands.
Between the toe of the escarpment and the M.L\v line is a 10 to 15
foot wide area of moderately slopin~: beach. The substrate on the
beach is similar to that of the lot with the addition of a moderate
amount of shell hash which was apparently left on the shore after
crosion cut the escarpment into the he3cll. Waterward of the MLW
line the bayhottom slopes downward more or less evenly until it
reaches a depth of 5 feet MLW at a distance of 30+ ft. waterward of
the MLW line. From the 5 foot MLW contour, the b~ttom slopes more
steeply downward to the harbor floor.
A fauna consisting of false ceriths (Batillaria minima), fuzzy
chiton (Acanthopleura ~ranulatar, paper oysters (Isogonomon sp.)
and barnacles was foun in the littoral zone of the site. Sub-
littoraly the near shore area is vegetated primarily by a mixture
of Cuban shoalweed (Diplanthera wrightii), and turtlegrass
(Thalassia testudinum). Frequent examples of Halimeda tuna,
Harlmeda incrassata~ Batophora sp., Penicillus sp., Udo~sp.,
Aceturbularia sp., Caulerpa spp., Padina sp., Jania sp., Laurencia
sp. and unidentified algae were found throughout the proposed dredge
area. Faunal elements consist of Tegula fasciata, fly specked
cerith (Cerithium muscarum), dwarf ccrith (Cerithiunl lutosum), hawk
wing conch (Strombus raninu~), moon snails (Natica sp.) hermit crabs,
grunt (Haernulon sp.) barracuda (SPh~raena sp.), stomatopods, tunicates,
sponges, star coral (Siderastrea Tn ians) ~nd lobsters (Panulirus
argus). In summary, the intertidal and shallow baybottom in the
project area is a very rich benthic marine biological association.

Construction of tIle seawall with associated backfill will permanently
eliminate the emergent and transitional wetlands along the project
sit c 's s h 0 r e 1 in c . Wit h the e 1 i m in at ion 0 [ the 'oJe t 1. and s the i r fun c -
tion as habitat, sources of primary production and upland runoff
filtration will also be eliminated. Placing riprap along the toe
o~t part of the seawall will tend to partially replace some of the
wetlands function as habitat.
v-
Construction related activities will tend to result in elevated
levels of turbiJity, dissolved organic compounds and particulate
organic compounds in the waters at and near the project site. Prop-
er use of turbidity curtains should be able to adequately control
these problems.
