COUNTY, FLORIDA, HAS RECEIVED AN APPLICATION FROM MR. & MRS. D.
R. DORN TO CONSTRUCT:
A VERT I CAL CONCRETE SEAWALL, 120' LONG, I S PROPOSED
TO PREVENT FURTHER EROSION OF THE SHORELINE. BACKFILL WITH A
TOTAL OF 205 CUBIC YARDS OF MATERIAL WILL BE DONE WHEN SEAWALL
HAS BEEN COMPLETED. FIVE WOODEN FENDER PILES WILL BE INSTALLED
NEXT TO THE SEAWALL TO ALLOW MOORING OF APPLICANT'S BOAT. THE
SEAWALL WILL EXTEND APPROX1MATELY 15' FROM THE PRESENT APPARENT
MHW LINE AT THE POINT WHERE EROSION IS MOST SEVERE.
THE PROJECT SITE IS BOUNDED ON THE WEST BY SISTERS CREEK,
A NATURAL WATERBODY. ACROSS SISTERS CREEK IS AN UNDISTURBED RED
MANGROVE (RHIZOPHORA MANGLE) AREA. To THE NORTH, EAST, AND SOUTH,
THERE ARE RESIDENTIAL LOTS THAT THROUGHOUT THE GENERAL AREA ARE
LESS THAN 10% DEVELOPED. SUBSTRATE IN THE AREA IS MARL. VEGETA-
TION CONSISTED OF SALTBUSH (BACCHARIS SP.) AND A GROUND COVER OF
SALTGRASS (DISTICHLIS SP. ).
SUBSTRATE IN THE PROJECT SITE AND THE ADJOINING UPLANDS
CONSISTED OF MARL. VEGETATION ON THE UPLANDS WAS SALTBUSH AND
SALTGRASS, AND BELOW THE MHW LINE IT WAS EXCLUSIVELY THE GREEN
ALGAE BATOPHORA SP. FAUNA WITHIN THE PROJECT SITE WAS LIMITED TO
CHITONS, PARROTFISH, AND SOME MINNOWS. EVIDENCE THAT THE SHORELINE
WAS, AND STILL IS, BEING ERODED COULD BE SEEN BY THE ROCK RIP-RAP.
THIS RIP-RAP HAD APPARENTLY BEEN PLACED TO CURB THE EROSION BUT THE
SHORELINE HAS SINCE ERODED BACK BEHIND THE RIP-RAP, AND

Dear Mr. and Mrs. Dorn:
Re: Monroe County, File No. 44-
11182-SE
A biological assessment has been made of your proposal as follows:
r-A vertical concrete seawall, 120' long, is proposed to
-prevent further erosion of the shoreline. Backfill
with a total of 205 cubic yards of material will be
done when seawall has been completed. Five wooden
fender piles will be installed next to the seawall to
allow mooring of applicant's boat. The seawall will
extend approximately 15' from the present apparent MHW . .,-E
line at the point where erosion is most severe. F (if ~ Lf Lj _ III 8 Z.
The project site is bounded on the west by Sisters
Creek, a natural waterbody. Across Sisters Creek is
an undisturbed red mangrove (Rhizophora mangle) area.
To the north, east, and south there are residential
lots that throughout the general area are less than
10% developed. Substrate in the area is marl. Vege-
tation consisted of saltbush (Baccharis sp.) and a
ground cover of saltgrass (Distichlis ~:r.
Substrate in the project site and the adjoining up-
lands consisted of marl. Vegetation on the uplands
was saltbush and saltgrass, and below the MHW line it
was exclusively the green algae Batophora sp. Fauna
within the project site was limited to Chi tons, parrot-
fish, and some minnows. Evidence that the shoreline
was, and still is, being eroded could be seen by the
rock rip-rap. This rip-rap had apparently been placed
to curb the erosion but the shoreline has since eroded
back behind the rip-rap.:] tU-..d...

This project will enhance water quality in Sisters
Creek by stabilizing the embankment and preventing
silt loading on the waterway. A slight wake from two
boats passing during the inspection suspended fine
marl from the bank and sent a small turbidity plume
out into the waterway. Gradual stabilization of all
eroding marl embankments within sisters Creek will be
beneficial:J ~
Under the provisions of Section 253.124, Florida Statutes, this
report must be read into the record and duly considered at the
same meeting at which the Board of County Commissioners takes
final action for local approval. Proof of local approval under
this section must be furnished this office, in addition to the
affidavits requested July 14, 1978, before we can conclude proc-
essing.
Sincerely,
