Resolution 218-1981RFSOLITTIO" NO. 218- 1981
T^THEREAS, the BOPR.D OF COUNTY COS 'TMISSIONFRS OF MONROE COUNTY,
•FLORIDA, has received an application from City of. Key West ,
and
P?HFRFP.S, 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 excavation of the terminal 1080 feet of an
existing spoil bank, involving approximately 3250 cubic yards landward
of MH'V and 420 cubic yards waterward of MHW.
Removal will. be performed by backhoe and all. spoil from the removal will
be trucker to Key West's sanitary landfill site.
Lena_th of the entire spoil bank is approximately one-half mile long.
The original application submitted. called for the excavation of this
entire spit down to the MLW line (approximately three feet down from the
existing elevation). The most recent application calls for excavation
of one half of the spit (approximately one quarter of a mile) to a. depth
of one foot below MLTAT. The width of the spoil bank averages about 30
feet. All presently existing mangroves on the spoil bank will remain.
The applicant has additionally proposed the excavation of a circulation
cut to`A7ards the base of the spoil bank. This cut will 'he 30 feet wide
and -.2 feet deep (P11SL) . This excavation will involve approximately 130
cubic vards. The sides of the circulation cut will be riprapped. as will
an approximate 50 foot long strip of submerged alnd runninc parallel to
the spoil bank on the north side.
The material to be removed is compacted marl. The purpose of this pro-
ject is to increase water circulation and to provide fill material for
the sanitary landfill site.
Silt screens will be utilized. during operation.
The project site is located on the eastern shoreline of Stock Island,
south cr. rut adjacent to, U.S. #1 and extending into Boca Chica Channel,
which connects the Gulf and the Atla.nti_c.
The channel from which the existing spoil bank was dredged connects a
large marina. with Boca Chica Channel. On the other side of thl, channel;
a much smaller amount of spoil was deposited. For the most part, the
waters in the vicinity of the spoil bank are shallow am display soft
bottoms with seaarasses.
To the south of the spoil bank and in order of their occurence is a
trailer T) r..k, a. corpground, a. boat ranufacturina facility, a commerciaal
.fishin- marina and. a fish house. Offshore of this general area are a.
hood many free floating l.iveaboard boats and as many sunken derelict Boats.
The spoil. bank in question was deposited before permitting requirer:.ents,
probably for the purpose of extablishing dredge equipment access. Although
eroded somewhat on the north side due to boat wake, it remains relatively
intact and is presently being_ used by many of the liveaboard boat resi-
dents for mainland access.
On the northern perimeter of this spoil bank, bea_inning at the base and
working from west to east, the shoreline retains a somewhat barren,
rocky littoral shelf that drops off into channel depth os about -8 feet
MLW. No emeraent shoreline vegatation exists on this side of the bank.
Further to the east and still on the same side, a good many hard bottom -
associated organisms were observed such as sponges (Haliclona rubens),
starfish (Echinaster sentus ), thin shelled oysters (Isognomon sp.), and
calcareous algaes (Halimeda sp.). In general, the bottom becomes rockier
with more carbonates to the eastern end of the spoil bank, in contrast to
looser, finer sediments near the basal end which supports a dominant
growth of green algae (Batophora sp.).
Charned depths seem to stray away from the spit toward its end. In
these wider, shallow areas, turtlegrass (Thalassia testudinum) and shoal -
weed. (Falodule wrightii) have become established, continuing around the
end of the spit and for the entire length of the southern perimeter of
the spit below MLW. Mixed in with these seagrasses on the southern
side are green algaes (Penicillus sp.) and brown algaes (Gracilaria sp.).
The southern shoreline has a good many derelict and abandoned vessels
which have been left or washed up onto the spit. Towards the end of the
spoil bank, buttonwood (Canocarpus erecta), and white mangroves (Lagun-
cularia racemosa) are the dominant species contained within a scattered
and patchy mangrove fringe. This mangove fringe is most distinguished
over the terminal and basal 400 feet of the spoil. bank. The basal man-
grove fringe is made up primarily of black mangroves (Avicennia germinans)
and red manaroves (Rhizophora mangle) and is lusher, denser, and more
submergent in nature than the terminal mangrove fringe. This is due
greatly to the higher degree of organic and detrital accumulation along
this stretch of shoreline.
Within the mangrove fringe on the south side of the spoil bank, a con-
siderable amount of trash, garbage and debris has been deposited and
accumulated.
If all excavation is done above MLW (on a horizontal plane) very little
established benthic flora will be destroyed. Although the depth of the
excavation may be as low as one foot below MLW (on a vertical plane) it
is felt that the bottom contours will find their own levels and that
reveaetation of seagrasses, algaes and possibly red mangroves will occur
in the long term.
Retention of the existing mangroves will be difficult to accomplish in
the dredge area, however, this loss should be less than significant con-
sidering overall gains in water circulation and the restoration of this
area to its original nature.
An additional positive impact will be the reduction of liveaboards and
their associated domestic wastes due to the partial elemination of their
mainland access.
BE IS 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
28th day of
meeting.

A. The applicant proposes the excavation of the terminal 1080 feet
of an existing spoil bank, involving approximately 3250 cubic
yards landward of MH17 and 420 cubic yards waterward of MHW.
Removal will be performed by backhoe and all spoil from the removal
will be trucked to Key West's sanitary landfill site.
Length of the entire spoil bank is approximately one-half mile long.
The original application submitted called for the excavation of
this entire spit down to the M W line (approximately three feet
down from the existing elevation). The most recent application
calls for excavation of one half of the spit (approximately one
quarter of a mile) to a depth of one foot below MLW. The width
of the spoil bank averages about 30 feet. All presently existing
mangroves on the spoil bank will remain.
The applicant has additionally proposed the excavation of a circu-
lation cut towards the base of the spoil bank. This cut will be
30 feet wide and -2 feet deep (MSL). This excavation will involve
approximately 130 cubic yards. The sides of the circulation cut
will be riprapped as will an approximate 50 foot long strip of
submerged land running parallel to the spoil bank on the north side.
The material to be removed is compacted marl. The purpose of this
project is to increase water circulation and to provide fill mater-
ial for the sanitary landfill site.
Silt screens will be utilized during operation.
B. The project site is located on the eastern shoreline of Stock Island,
south of, but adjacent to, U.S. 41
vl and extending into Boca Chica
Channel, which connects the Gulf and the Atlantic.
The channel from which the existing spoil bank was dredged connects
a large marina with Boca Chica Channel. On the other side of this
channel, a much smaller amount of spoil was deposited. For the
most part, the waters in the vicinity of the spoil bank are shallow
and display soft bottoms with seagrasses.
To the south of the spoil bank and in order of their occurence is
a trailer park, a campground, a boat manufacturing facility, a
commercial fishing marina and a fish house. Offshore of this
general area are a good many free floating li.veaboard boats and as
many sunken derelict boats.
The spoil bank in question was deposited before permitting require-

access. Although eroded somewhat on the north side due to boat
wake,•it remains relatively intact and is presently being used
by many of the liveaboard boat residents for mainland access.
C. On the northern perimeter of this spoil bank, beginning at the base
and working from west to east, the shoreline retains a somewhat
barren, rocky littoral shelf that drops off into channel depths of
about -8 feet 11LW. No emergent shoreline vegetation exists on this
side of the bank. Further to the east and still on the same side,
a good many hard bottom -associated organisms were observed such as
sponges (Haliclona rubens), starfish (Echinaster sentus), thin

Retention of the existing mangroves will be difficult to accomplish
in the dredge area, however, this loss should be less than signifi-
