Resolution 365-1981
RESOLUTION NO.

WHEREAS, the BOARD OF COUNTY COMMISSIONERS OF MONROE COUNTY,
FLORIDA, has received an application from Gunnar D. Svalmark
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 bulkhead his waterfront property shoreline
on Key Largo, Monroe County. The proposed bulkheading will consist
of a total of 200+ linear feet of concrete-reinforced seawall
extending between-the +1.0 and -1.5 ft. (MHW) elevations along both
the property's Atlantic Ocean (66~ In. ft.) and canal front (135~
In. ft.) shorelines. The proposed seawall will match the height,
thickness and shoreline contour of two existing seawalls on adja-
cent properties. In addition, said seawall constructed will
require the deposition of approximately 20 cu. yds. of "clean,
coral rock" backfill materials to match the existing upland
property elevation.
The applicant's property is located within the Sunrise Point Sub-
division (S.P.S.) in southeastern Key Largo, Monroe County. S.P.S.
consists of a small (26 acre), single family residence (S.F.R.),
waterfront community on the Atlantic Ocean side of Key Largo.
S.F.R. "waterfront" within this community is provided by a series
of three, 1,000+ ft. long by 50+ ft. wide deadend finger canals
and one, 250+ ft. long by 25+ ft. wide canal all of which are
connected to-a series of shoreline peripheral canals providing
access to the Atlantic Ocean. Atlantic Ocean waters in this area
are Class III (Sect. 17-3.081; FAC). Approximately half of the
available properties within this subdivision are presently developed
with many additional residences observed to be under construction
at the time of inspection. The majority of the existing S.F.R's
are equipped with some type of boat mooring (ie, docks, basins)
and/or launching facilities (ie, ramps, davits).
The applicant's property consists of an average-size rectangular,
residential lot bordered to the south and northwest by similar
residential properties, to the northeast by an unnamed, artifi-
cially created, deadend finger canal and to the southeast by a peri-
pheral channel to the Atlantic Ocean. Both of the adjacent residen-
tial properties are developed with existing two-story S.F.R's (and
associative facilities) and, as a result, are presently vegetated
by largely landscaped flora. As mentioned in the application, both
of these properties are presently equipped with concrete seawall
bulkheads/docks similar to that proposed here. The applicant's
upland property, although presently undeveloped, is somewhat dis-
turbed. Most of the central property areas have been cleared of
vegetation to provide storage space for several pieces of heavy
construction equipment (ie, backhoe w/flatbed). As a result, there
is presently little significant remaining upland vegetation. The
predominant substrate in this area is Key Largo oolitic limestone.
The proposed project area consists of the applicant's shoreline
property and adjacent transitional and submergent lands. Property
transitional areas presently consist of a 20-30 ft. wide fringe
growth along both the existing canalfront and oceanfront shorelines.
Vegetation observed in these areas included sea daisy (Borrichia
spp.), purslane (Sesuvium spp.), blite (Suaeda spp.), glasswort
(Salicornia spp.), buttonwood (Conocarpus spp.) and small red
Resolution

(Rhizophora spp.) and black (Avicennia spp.) fringing mangroves.
Although apparently stable at present, the gradually sloping shore-
line grade observed throughout the project area suggest that some
erosion has occurred along this property shoreline. Isolated coral
rock boulders along Atlantic Ocean/peripheral channel property
shoreline areas suggest that some type of riprap revetment once
existed in this area.
The adjacent unnamed artificial canal is 75 ft. wide by 1,000 ft.
long (deadenc finger orientation) by 10! ft. deep (MLW). Submergent
vegetation observed in this area consisted of green and brown algal
patches along the upper portions of the canal walls and in adjacent
littoral areas. Water quality within said canal appeared good at
the time of inspection. The Atlantic Ocean (southwestern) property
shoreline is presently bordered by a 60~ ft. wide by 1,000~ ft. long
(parallel to shoreline) by 8-10 ft. deep (MLW: varies) artificia1ly-
created peripheral channel. This channel is protected on its entire
waterward (ocean) periphery by a boulder riprap breakwater. Ocean
access from said channel is presently available via access channel
cuts existing at each channel end. Channel biota observed included
the algal species listed above and several unidentified species of
juvenile fish. Water quality within this channel area appeared
excellent.
The primary direct project impact will be in the removal and loss of
approximately 5,000 sq. ft. of transitional and wetlands vegetation
presently growing within the proposed seawall and back fill constru-
tion areas. This vegetation presently provides shoreline stabili-
zation, storm runoff filtration and detrital nourishment for the
enhancement of both the adjacent upland and submergent marine
ecosystems.
Indirect project effects include elevated turbidity levels within
state waters during project construction activities and the loss of
an unspecified amount of presently valuable littoral microhibitat
area through long term seawall bottom-scouring effects.
Under the provisions of Chapters 253, 123, 253.124, 403.087 of the
Florida Statutes and Sections 17-3.121 (28) and 17-4.07 of the
Florida Administrative Code, I hereby recommend that this applica-
tion for permit be denied Departmental approval unless one of the
following alternative suggestions can be incorporated into the
overall project design:
1. Specification that 1imerock boulder riprap (2~ ft. diameter)
be placed along the toe of said seawall structure approxima-
ting a 1:1 slope (ie, 45 degree angle). OR:
2. Specification that a meandering (ie, following contours of
existing shoreline), large diameter (3 to 1 ft.), boulder
riprap revetment with filter sand retainer material be
substituted for said seawall structure. Retainer material
will be placed both beneath and behind said revetment
structure. The revetment structure's waterward face will
approximate a 1:1 slope.
The latter alternative (riprap revetment) provides the additional
benefits of reduced cost, additional microhabitat surface area and
a more natural appearnace.
In addition, it is recommended that the following construction pro-
cedures be utilized in the interest of preserving state water quality.

1. Turbidity curtains be utilized during seawall/revetment
construction (placement) activities.
2. Backfill materials be deposited to form a reverse slope
away from said bulkhead structure to prevent excessive
upland storm runoff.
3. No fuel or fuel products be stored upon said bulkhead
facility.
BE IT RESOLVED BY THE BOARD OD 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 Borad of County Commissioners of Monroe
County, Florida, this
day or
19
at a regularly scheduled meeting.

Dear r~r. Svalmark:
Reference is made to your permit application dated 29 March 1981 concerning
replacement of a reinforced seawall with backfill in the Florida Straits,
Section 13, Township 58 South, Range 38 East, Key Largo, Monroe County,
Florida.
The project as proposed is authorized by General Permit SAJ-l9, a copy of
which is attached for your information and use. You are authorized to
proceed with the project in accordance with the attached drawings subject
to ~ conditions of the permit.
This letter of authorization does not obviate the necessity to obtain any
other Federal, State, or local permits which may be required.
It appears that a permit from the Florida Department of Environmental Regu-
lation may be required. They can be contacted at (813) 639-4967.

Dear Mr., Svalmark:
Enclosed is a site inspection report indicating that your project,
as proposed, will have an adverse impact on the environment.
However, with the modifications suggested by the inspector, the
impact could be lessened to an extent which would eliminate the
justification for' the denial recommendation. Please consider
these modifications. If you feel that you can modify your
proposal as indicated, or in some other manner which would
reduce the adverse impact on the environment, please submit a
revised sketch/letter of agreement to the changes by 8-31-81
If we have not heard from you by this date or if you do not wish
to modify your proposal as suggested, we will continue to process
your application as submitted.
Eric Loken of this office will be glad to
answer any questions you may have concerning ~~e suggested
modifications. Mr. Loken can be reached at the Marathon DER
office (305) 743-5955.

A. The applicant l)roposes to bulkhead his ,00aterfront property shoreline
on Key Largo, rlonroe County. The pro?osed bulkheading will consist
of a total of 200+ linear feet of concrete-reinforced seawall
extending bet'ltleen-the +1,0 and -1. 5 ft. (HHH) elevations along both
the nroJertv's Atlantic Ocean (A6+ ln ft.) and canalfront (135+
ln, ~t.~ sh~relines, The nro~oseJ seawall will match the heighi,
thickness and shoreline contour of th'O existing semvalls on adja-
cent prooerties, In addition, said seawall construction will
require the deposition of anuroximately 20 cu, yds. of "clean,
coral rock" backfill materials to match the existing upland
property elevation,
B. The applicant's nronerty is located within the Sunrise Point Sub-
division (S.P.S.) in southeastern Key Largo, Monroe County, S.P.S,
consists of a small (26 acre), single family residence (S.F.R.),
waterfront COTI1Tnuni ty on the Atlantic Ocean side of Key Largo.
S. F. P.. "waterfront" ",vi thin this communi ty is provided by a series
of three, 1,000~ ft. long by 50! ft \vide deadend finger canals
and one, 250+ ft. long by 25+ ft, wide canal all of which are
connected to-a series of shoreline oeriryheral canals ~roviding
access to the Atlantic Ocean, Atlantic Ocean waters in this area
are Class III (Sect. 17-3,08l; FAC). Approximately half of the
available properties within this subdivision are presently developed
with TIlany additional residences observed to be under construc~ion
at the time of inspection, The majority of the existing S.F.R's
are equi??ed with some type of boat mooring (ie, docks, basins)
and/or launching facilities (ie, ramps, davits).
The applicant's property consists of an average-size rectangular,
residential lot bordered to the south and northwest by similar
residential ;::>ro-:Jerties. to the nortlleast by an unnaIlled, artificially--
created, deadend finger canal and to the southeast by a peripheral
channel to the Atlantic Ocean Doth of the adjacent residential
properties are developed with existing two-story S.F.R's (and
associative facilities) and, ilS 2 result, are presently vegetated
by largely landscaped flora, As mentioned in the a9plication, both

The proposed project area consists of the applicant's shoreline
property and adjacent transitional and subm~rgent lands. Property
transitional areas presently consist of a 20-30 ft, wide fringe
growth along both the existing canalfront and oceanfront shorelines
Vegetation observed in these areas included sea daisy (Borrichia
spp.), purslane (Sesuvium Spy ). blite (Suaeda spp.), glasswort
(~alicornia SP?,), buttom'lOod (Cono~us spp,) and small red
(Rhizophora spp.) and black (Avicennia spp.) fringing mangroves.
Although ap?arently stable at present, the gradually sloping shore-
line grade observed throughout the project area suggests that some
erosion has occurred along this property shoreline. Isolated coral
rock boulders along Atlantic Ocean/peripheral channel property
shoreline areas suggest that some type of riprap revetment once
existed in this area.
The adjacent unnaoed artificial canal is 75 ft. wide by 1,000 ft. long
(deadend finger orientation) by 10~ ft, deep (l1LH). Submergent
vegetation observed in this area consisted of green and brown algal
patches along the upper portions of the canal walls and in adjacent
littoral areas. Hater quality '\vithin said canal appeared good at
the time of inspection. The Atlantic Ocean (south'\vestern) uroperty
shoreline is presently bordered by a 60+ ft. wide by 1,000+ ft. long
(parallel to shoreline) by 3-10 ft, deep (I1LH; varies) artlficially-
created peripheral channel This channel is ~rotected on its entire
waterward (ocean) periphery by a boulder riprap break'\vater. Ocean
access from said channel is nresentlv available via access channel
cuts existing at each channel end. Channel biota observed included
the algal species listed above and several unidentified species of
juvenile fish. Hater quality Hi thin this channel area appeared
excellent.
D.
The pr~mary dire~t project impact llill be in the removal and loss of
approxlmately ~.,-,OO.sq: ft,- of transitional and wetlands vegetation
p~esently growlng wlthln tne proposed seawall and backfill constru-
tlO~ areas. This vegetation presently orovides shoreline stabili-
zatlon, storm runoff filtration and detrital nourishment for the
enhancement of both the adjacent upland and submergent marine
ecosystems.
Indirect project effects includ~ elevated turbidity levels within
state wat~r~ ~uring project construction activitie~ and the loss of

E. Under the provisions of Chanters 253.123, 2S3.124, 403.087 of the
Florida Statutes and Sectio~s 17-3.121(28) and 17-4.07 of the
Florida Administrative Code, I hereby recommend that this applica-
tion for permit be denied Departmental approval unless one of the
follo\ving alternative suggestions can be incorporated into the
overall project design:
'~
_~ I, Specification that lirnerock boulder riprap (2~ ft. diameter)
be placed along the toe of said seawall structure approximating
a l:l slope (ie, 45 degree angle). OR:
2. Specification that a meandering (ie, following contours of exis-
ting shoreline), large diameter (3 to I ft.), boulder riprap
revetment 'vith filter sand retainer material be substituted for
said seawall structure. Retainer material will be nlaced both
beneath and behind said revetment structure. The r~vetment
structure's waterward face will approximate a l:l slope.
The latter alternative (riprap revetment) provides the additional
benefits of reduced cost, additional microhabitat surface area and
a more natural appearance,
In addition, it is recommended that the following construction pro=
cedures be utilized in the interest of preserving state water
quality:
1. TU1:bidity curtains be utilized during seawall/revetment con-
struction (placement) activities. .
2. Backfill materials be deposited to form a reverse slope away
from SQid bulkhead structure to prevent excessive upland storm
runoff.
3. No fuel or fuel products be stored upon said bulkhead facilitv.
