has receiven an application from RH~~, INt. ,
ann
WHEREAS, in comp1aince with $tate $tatute, it is necessary as part of
the permitting procenure to rean the following Biological Assessment into
the Recorn, as follows:
The applicant is proposing the construction of a riprap and seawall revet-
ment along two sides of a triangular parcel of land measuring approximately
300' x 350' x 400'. Those sides of the property facing the water, which
would be subject to the proposed construction, measure about 300 feet (open-
water shoreline) and 400 feet (canal shoreline). Of the 400 feet of canal
shoreline to be stabilized, 100 feet would be seawalled. The remainder of
the canal shoreline and all of the open-water shoreline would be riprapped.
The applicant claims that 300 cubic yards of fill would be placed above the
line of mean high water (MHW) and that 300 cubic yards of fill and riprap
would be placed below MHW. The proposed plans call for a 23' extension of
the open-water shoreline waterward of the present erosion line. Of the 23'
wide area filled, the vast majority would consist of backfill. The waterward
toe of the riprap would rest at the mean low water (MLW) line, as proposed.
Filter cloth would be utilized behind the proposed riprap.
Along the canal shoreline, riprap would be placed at the mean sea level (MSL)
line, landward of an existing mangrove fringe. Filter cloth would also be
used here.
The proposed seawall would be constructed out to the deep water dropoff of
the canal. Davits would be constructed on the seawall.
The purpose of this project is to provide erosion protection for the
applicant's property. The intended usage of this property is private and
recreational, according to the applicant.
All work would apparently be performed from the uplands.
The project site is located on the southern end of Summer land Key facing the
shallow waters of Summerland Cove. Most of this area has been dredged or
filled for residential development, although a large parcel of land exists
immediately to the north of the project site, which remains in a semi-
natural state (most of this parcel is undisturbed mangrove wetland,
although permits #44-10464-5E and #440690245 were issued to Joseph Fisher
for the placement of a small amount of fill in wetlands, the construction of
a boardwalk and the excavation of a boatslip within this parcel).
To the south of the project site, Snug Harbor subdivision is encountered
with its canals and filled residential lots.
The actual project site appears to be the result of dredge and fill work
performed during the development of this subdivision. Specifically, the
project site has been filled, probably with canal dredge spoil.
Across from the canal, which borders the project site, the residential
lots have been developed as homesites. As part of this development, the
canal shoreline on this side has been seawalled, for the most part, and at
least one boatslip was observed.
The canal which borders one side of the applicant's property is part of a
dredged canal and channel network which connects all of the lots in the
general area. The main channel parallels the open-water shoreline over
most of the south side of Summerland Key, including the west side of the
project site and the adjacent northern property. This channel has a
controlling depth of about -2' to -3' at MLW.
RESOLUTION NO.

Since initial dredge and fill work was performed in and around the
applicant's lot, red mangroves (Rhizophora mangle) have colonized along
the canal side of the applicant's property.
Within the perimeter channel, which parallels the open-water shoreline,
and within parts of the adjacent canal, seagrasses (Thalassia testudinum
and Halodule wrightii) have also become established.
The open-water shoreline has eroded substantially since initial filling.
As a result, few mangroves have been able to become established, except
over the southwest corner of the property.
The "upland" or filled portion of the lot exhibits elevations estimated
to be about two to three feet above MSL. Although this filled lot does
not become inundated during regular annual tides, its vegetation is
composed primarily of salt-tolerant species, including, but not limited to,
buttonwoods (Conocarpus erecta), drop seed (Sporobolus sp.), sea daisy
(Borrichia sp.), and key grass (Monanthochloe littoralis). The elevation
of this lot is such that additional fill will probably be required for
further development.
At the erosion line of the applicant's property, buttonwoods, sea daisy
and seagrape (Coccoloba uvifera) are particularly prevalent.
Along the open-water shoreline of this property, erosion has accounted
for an intertidal area which ranges from about l6' to 23' in width. This
zone is characterized by barren rock rubble over all but the southwest
corner, where red mangroves and black mangroves (Avicennia germinans)
have grown to heights approaching eight feet. It is interesting to note
that the undisturbed shoreline to the north of the applicant's property
displays lush red mangrove growth which extends nearly to the offshore
perimeter channel.
The waterward extent of the intertidal zone is well-defined by a distinct
cut that has been made along the shoreline (it was probably made at the
time the perimeter channel was excavated). Waterward of this cut, perman-
ently submergent beds of seagrass are encountered, along with several
species of anemones. Also observed in this area was a single blue crab
(Callinectes sapidus) and a barracuda (Sphyraena barracuda).
Numerous plovers (Charadriidae) were observed along the water line at the
time of the inspection.
The canal shoreline drops gently over much of its length, supporting sea-
grasses over the more horizontal bottom surfaces. Red mangrove growth
along this shoreline is significant, but not particularly high.
Anticipated impacts are as follows:
I) Elimination of some mangroves along the open-water and canal shorelines
which contribute to good water quality and the marine food chain.
2) Elimination of a small, permanently submergent area of seagrass
(Halodule) over the southwest corner of the property.
3) The creation of a shoreline discontinuity where the applicant's
property abuts the natural mangrove shoreline to the north.
4) Increased likelihood of prop dredging within shallow channel waters
with the introduction of a large (I50') boat into the bordering
canal system.
5) Some benefit may be derived from this project as a result of shore-
line stabilization and habitat creation from riprap placement.

As provided in Section 253.l23 and Chapter 403 of the Florida Statutes,
and in accordance with Sections 17-3.051(1), 17-3.121(7) and 17-4.242 of
the Florida Administrative Code, it is recommended that this application
be modified prior to permitting approval.
It is suggested that in order to accomplish the intended purpose of shore-
line stabilization, the applicant limit the waterward extent of the proposed
riprap revetment to the line of mean sea level, or, approximately ten feet
waterward of the present erosion line. This would place the toe of the
proposed riprap revetment 13 feet landward of the submergent vegetation
line at the north end of the open water shoreline and about six feet
landward of this line on the south end.
In this way, the existing mangrove fringe can be retained and a shoreline
discontinuity can be avoided at the northern property line.

Key, Monroe County, Florida. Zoned RU-l.
INTRODUCTION
This application, for the placement of fill below the mean high water line
(MHW), is to be reviewed by the Monroe County Commission pursuant to
Section 19-1l1(a) (5) of the Monroe County Code.
PROJECT AND SITE DESCRIPTION
The applicant proposes to construct 400 feet of riprap seawall, a 100 foot
concrete seawall and a boat ramp. Only the construction of the boat ramp
will require the placement of 25 cubic yards of fill below the MEW.
While an FDER bio-assessment is included in this report, the attached
application drawing reflects modification recommended by the FDER. The
parcel is a previously disturbed site where dredge and fill activities
have taken place. Today, a small, relatively unvegetated subtidal shelf
is the site where the boat ramp is proposed.
EVALUATION
This activity will result in little or no adverse environmental impact.
The associated seawalls, being constructed landward of MHW, will service
the property in protecting the shoreline from further erosion.

Dear Mr. Cantrell:
In reference to your biological report, page 5 item E,
and our letter of 5/21/84, please find enclosed the revised
drawings which reflect the following:
1. North end: we are placing the toe of the proposed
rip-rap revetment 13' landward of the submergent vegetation
line and, at the south end, approximately 6' landward, for
a total distance of 300'. See page 1 and page 2 (cross-sec-
tion). Please note that we have included a proposed boat
ramp of 12' Y 16' a t the north end.
2. We have eliminated the solid poured seawall and are
now proposing a 4'x80' dock with four 4'xlO' elevated walk-
ways cantilevered over the existing mangroves and thereby
preserving the shoreline vegetation in between the elevated
walkways. See page 1 and page 3.
3. To meet the concerns of the neighbor across the channel,
Kenneth Hanna, we have moved the proposed 80' dock 50' to the
west so that it would not inhibit his deep water access out
of his boat slip if a boat were moored at the proposed dock.
4. We have eliminated the rip-rap along"the man made
channel and have revised tne project to an upland retainer
wall landward of the existing mangroves. See page 4. It is
our understanding that the +300' retainer wall would not re-
quire an Army Corps or State permit. Please advise.

A. The applicant is proposing the construction of a riprap and
seawall revetment along two sides of a triangular parcel of
land measuring approximately 300' x 350' x 400'. Those
sides of the property facing the water, which would be
subject to the proposed construction, measure about 300
feet (open-water shoreline) and 400 feet (canal shoreline)
Of the 400 feet of canal shoreline to be stabilized, 100
feet would be seawalled. The remainder of the canal shore-
line and all of the open-water shoreline would be riprapped.
The applicant claims that 300 cubic yards of fill would be
placed above the line of mean high water (MHW) and that
300 cubic yards of fill and riprap would be placed below
MHW. The proposed plans call for a 23' extension of the
open-water shoreline waterward of the present erosion line.
Of the 23' wide area filled, the vast majority would
consist of backfill. The waterward toe of the riprap would
rest at the mean low water (MLW) line, as proposed. Filter
cloth would be utilized behind the proposed riprap.
Along the canal shoreline, riprap would be placed at the
mean sea level (MSL) line, landward of an existing mangrove
fringe. Filter cloth would also be used here.
The proposed seawall would be constructed out to the deep
water dropoff of the canal. Davits would be constructed on
the seawall.
The purpose of this project is to provide erosion protection
for the applicant's property. The intended usage of this
property is private and recreational, according to the
applicant.
All work would apparently be performed from the uplands.
B. The project site is located on the southern end of Summerland
Key facing the shallow waters of Summerland Cove. Most of
this area has been dredged or filled for residential devel-
opment, although a large parcel of land exists immediately
to the north of the project site, which remains in a semi-
natural state (most of this parcel is undisturbed mangrove
wetland, although permits #44-l0464-5E and #440690245 were
issued to Joseph Fisher for the placement of a small amount
of fill in wetlands, the construction of a boardwalk and
the excavation of a boatslip within this parcel) .
To the south of the project site, Snug Harbor subdivision
is encountered with its canals and filled residential lots.

The actual project site appears to be the result of dredge
and fill work performed during the development of this
subdivision. Specifically, the project site has been
filled, probably with canal dredge spoil.
Across from the canal, which borders the project site, the
residential lots have been developed as homesites. As
part of this development , the canal shoreline on this side
has been seawalled, for the most part, and at least one
boatslip was observed.
The canal which borders one side of the applicant's property
is part of a dredged canal and channel network which connects
all of the lots in the general area. The main channel
parallels the open-water shoreline over most of the 'south
side of Surnmerland Key, including the west side of the
project site and the adjacent northern property. This
channel has a controlling depth of about -2' to -3' at MLW.
C. Since initial dredge and fill work was performed in and
around the applicant's lot, red mangroves (Rhizophora mangle)
have colonized along the canal side of the applicant's
property.
Within the perimeter channel, which parallels the open-water
shoreline, and within parts of the adjacent canal, seagrasses
(Thalassia testudinum and Halodule wrightii) have also
become established.
The open-water shoreline has eroded substantially since initial
filling. As a result, few mangroves have been able to become
established, except over the southwest corner of the property.
The "upland" or filled portion of the lot exhibits elevations
estimated to be about two to three feet above MSL. Although
this filled lot does not become inundated during regular
annual tides, its vegetation is composed primarily of salt-
tolerant species, including, but not limited to, buttonwoods
(Conocarpus erecta), drop seed (Sporobolus sp.), sea daisy
(Borrichia sp.), and key grass (Monanthochloe littoralis).
The elevation of this lot is such that additional fill will
probably be required for further development.
At the erosion line of the applicant's property, buttonwoods,
sea daisy and seagrape (Coccoloba uvifera) are particularly
prevalent.

Along the open-water shoreline of this property, erosion
has accounted for an intertidal area which ranges from about
16' to 23' in width. This zone is characterized by barren
rock rubble over all but the southwest corner, where red
mangroves and black mangroves (Avicennia germinans) have
grown to heights approaching eight feet. It is interesting
to note that the undistrubed shoreline to the north of the
applicant's property displays lush red mangrove growth which
extends nearly to the offshore perimeter channel.
The waterward extent of the intertidal zone is well-defined
by a distinct cut that has been made along the shoreline
(it was probably made at the time the perimeter channel was
excavated). Waterward of this cut, permanently submergent
beds of seagrass are encountered, along with se~ra~ species
of anemones. Also observed in this area was a single blue
crab (Callinectes sapidus) and a barracuda (Sphyraena
barracuda) .
Numerous plovers (Charadriidae) were observed along the water
line at the time of the inspection.
The canal shoreline drops gently over much of its length,
supporting seagrasses over the more horizontal bottom sur-
faces. Red mangrove growth along thi~ shoreline is signifi-
cant, but not particularly high.
D. Anticipated impacts are as follows:
1) elimination of some mangroves along the open-water and
canal shorelines which contribute to good water quality
and the marine food chain.
2) elimination of a small, permanently submergent area of
seagrass (Halodule) over the southwest corner of the
property.
3) the creation of a shoreline discontinuity where the
applicant's property abuts the natural mangrove shoreline
to the north.
4) Increased ~ikelihood of prop dredging within shallow channel
waters with the introduction of a large (+50') boat into
the bordering canal system.
5) some benefit may be derived from this project as a result
of shoreline stabilization and habitat creation from rip-
rap placement.

E. As provided in Section 253.123 and Chapter 403 of the Florida
Statutes, and in accordance with Sections 17-3.051(1),
17-3.121(7) and 17-s.242 of the Florida Administrative Code,
it is recommended that this application be modified prior
to permitting approval.
It is suggested that in order to accomplish the intended
purpose of shoreline stabilization, the applicant limit the
waterward extent of th~ proposed riprap revetmpn~ tn the line
of mean sea Ipvel, or, approximatelv ten feet waterward of
the present erosion line. This would place the toe of the
~oposed riprap reve~t 13 feet landward of the submergent
vegetation line at the north end or the apen water shoreline
and about six feet landward of this line on the south end,.
-
In this way, the existing lmangrove fringe can be retained and
a shoreline discontinuity can be avoided at the northern
property line.
