RE: Baron Island Storage
Relief Request for Land Dev. Code Chapter 7.04.01C
Permit No. 2010-0252
Dear Jodi,
The purpose of this letter is to request relief in reference to Land Development Code
Chapter 7.04.01 C that states that the minimum required floor elevation is 18" above the
center line of the adjacent road. This request for relief is in reference to the Baron Island
Storage project located at 9563 S Ocean Dr Building A, Jensen Beach, FL 34957.
The Baron Island Storage project involves the construction of a storage facility along with
associated parking and stormwater retention areas. The storage facility consists of 77
storage units and a small 250 square foot office. A 10-2 self -certification has been issued
for the stormwater management system by the South Florida Water Management District.
According to the latest FEMA FIRM, the project takes place in flood zone category "AE"
that has a base flood elevation of 4.00 NAVD, which provides floodplain storage of 0.62
ac-ft of volume.
Due to the development of the site, a floodplain compensation calculation was performed
to determine the required volume of compensatory storage. The proposed finished floor
elevation of the site is 6.00 NAVD, which is above the 100-year flood stages found in the
stormwater modeling of the site. The center line elevation of the adjacent road, which is
State Road A1A, is approximately +/- 5.55 NAVD. Calculations were completed on raising
the finished floor above the proposed elevation however, flood compensation could not
be met with a finished floor elevation above 6.00 NAVD. The finished floor elevation of
www.EDC-inc.com
6.00 NAVD is the highest practical elevation while accommodating for the required
floodplain compensation storage.

We believe the submitted information will satisfy the requirements for a request for relief
of the County's Land Development Code.
