A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF DELRAY
BEACH, FLORIDA, OF APPROVAL FOR CONSTRUCTION OF A "T"
PILE AND SLAB TYPE, CONCRETE SEAWALL AND BACKFILL
WHERE APPROPRIATE, FOR THE PRI~.{ARY PURPOSE OF PREVENT-
ING EROSION ON LOT 350, TROPIC ISLE, 3RD SECTION, CITY
OF DELRAY BEACH, AS RECORDED IN PLAT BOOK 25, PAGE 37,
PUBLIC RECORDS OF PALM BEACH COUNTY, FLORIDA.
WHEREAS, a request has been made by John A. Grant, Jr., Consulting
Engineer, as representativ~ of the applicant, to construct a seawall on
the above-described property to halt erosion which is taking place due to
the wake action from heavy boat traffic in the area. The finger islands
both to the north and south of this project are bulkheaded, as is most of
the waterfront property on the east side of the Intracoastal Waterway. The
seawall is to be installed on the Bimini Finger Canal on the Intracoastal
Waterway, to the north, and 45 feet into property on the south side, and
WHEREAS, this approval by City Council of Delray Beach, Florida, will
be required, as set out in Florida State Regulations, Chapter 253.124 be-
fore application for approval for said construction of seawall can be made
to United States Army Corps of Engineers, and
WHEREAS, the City Engineering Department has examined this request
for the construction of a seawall on Lot 350, Tropic Isle, 3rd Section,
City of Delray Beach, as recorded in Plat Book 25, Page 37, Public Records
of Palm Beach County, Florida, and certifies it to be within the require-
ment ~f the City of Delray Beach, Florida, and the City Manager recommends
that the City of Delray Beach approve the request for said construction
of a seawall for the primary purpose of preventing erosion on the above-
described property, and
WHEREAS, the State of Florida Department of Environmental Regulation
submitted a Permit Application Appraisal No. DF 50-5982 including a recom-
mendation for approval to construct the proposed seawall, a copy of which
is attached hereto and made a part hereof of this Resolution in compliance
with Chapter 253.124, Florida Statutes. This Resolution to supercede
Resolution #49-78.
WHEREAS, it is the Council's opinion that the approval of this
request would be in the best interest of the City,
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF
DELRAY BEACH, FLORIDA, AS FOLLOWS:
Section 1. That said request for construction of a seawall on
Lot 350 in Tropic Isle, 3rd Section, City of Delray Beach, as recorded in
Plat Book 25, Page 37, Public Records of Palm Beach County, Florida, for
the primary purpose of preventing erosion of said property be approved.

A. Description of proposed project and construction techniques. Quantify area of project which extends into wetlands
and/o~ waterward of the apparent mean high water line.
Construct below the line of mean high water 2~0+__. feet of
vertical bulkhead and backfill with 1125 cubic yards of
clean fill.

The Intracoastal Water~ay in this area is a man-made lan~ cut an~
its shoreline is bulkheaded along 80~ of its length. There is
little natural shoreline vegetation (mangrove, etc.) existing in
this section of the Intracoastal Waterway.
C. Biophysical features of specific , project site {and spoil site when appropriate, include identification of bottom types).
~The proposed project is to be constructed north and south along
the western shoreline of the Intracoastal Waterway and then west
into an existing finger canal.
The upland of this job site is vegetated by AuStralian pine
(Casuarina sp.), several Brazilian peppers (Schinus sp.)and several
white mangroves (~a~uncularia racemosa).
This project site indicates that erosio'n has taken place. The bottom
type of the Intracoastal Waterway in this general area is sand with
a light layer of organics and should be considered good in terms of
biological productivity. ,

D. Impact of projecl; on biological resources. Address long-term inpacl as well as immediate impact. All aspects of propos,~
should be ~ssessed ~n these terms:;
The i~:mediate impact will be the loss of organisms that dwell
in the substrate within the proposed fill area.
The long-term effect will be the loss of the intertidal zone
within the proposed fill area.
E. Recommendation, with justification, concerning application. Include references to statutes, administrative rules, etc..
Approve, as the property involved definitely appears to have been
eroded and is essentially the last such lot in the area.
F. Suggest ion concerning modifications to reduce or minimize impact where appropriate.
Riprap should be placed at the toe of the bulkhead at a 2/1 Slope.
