Flood Prone Areas<br />
Areas subject to flooding conditions at the time of this report are identified on The Coastal High<br />
Hazard Area Map in the Future L<strong>and</strong> Use Map Series.<br />
Flooding<br />
Periodic street flooding has been a concern in various parts of the City since early in the City's<br />
history. Conditions contributing to flooding are:<br />
A. Relatively flat terrain <strong>and</strong> associated low hydraulic gradient requiring large-size drainage<br />
structures.<br />
B. Wind, tidal, <strong>and</strong> water table characteristics which occasionally combine to produce a high<br />
stage in receiving waters at system discharge points <strong>and</strong> cause drainage system<br />
surcharging, diminishing the ability of the system to cope with storm loadings.<br />
C. Structures incapable of h<strong>and</strong>ling quantities of runoff characteristic of the area.<br />
D. Construction st<strong>and</strong>ards (or lack thereof) which in the past failed to provide structural<br />
integrity, alignment, <strong>and</strong> performance in stormwater management structures.<br />
E. Flow blockage <strong>and</strong> impediments (roots, s<strong>and</strong>, yard waste, news <strong>and</strong> advertising<br />
publications, <strong>and</strong> general debris) which restrict or block water flow.<br />
In 1974, the City of <strong>Satellite</strong> <strong>Beach</strong> funded a study to determine the extent of the drainage problem<br />
<strong>and</strong> obtained recommendations for improvements. In 1976, a drainage master plan was devised<br />
which provided for a five-year interval storm design by replacing <strong>and</strong>/or reconstructing the existing<br />
system at a cost of approximately $3 million (1976 dollars). The plan was completed in November,<br />
1976 <strong>and</strong> was submitted with the City's application for a Federal grant to upgrade the City's drainage<br />
system. The grant was not approved. A subsequent tax increase referendum to fund a recommended<br />
$4.5+ million (1984 dollars) in major improvements was rejected by 93% of the City's voters in<br />
1984. In 1985, citizens were polled on the City's level of services <strong>and</strong> expenditures; most responded<br />
that flooding was not perceived as a major problem. Since the failed referendum, the City was<br />
forced to continue to pursue drainage system repair <strong>and</strong> improvement.<br />
Drainage along State Road A1A<br />
Stormwater runoff along SR A1A would flow naturally from east to west given topographic<br />
conditions. However, the drainage system installed along SR A1A directs stormwater eastward.<br />
Two regulations addressing stormwater drainage on beaches <strong>and</strong> related matters are Department of<br />
Environmental Protection, Chapter 17-4.248, Florida Administrative Code <strong>and</strong> St. Johns River Water<br />
Management District, Chapter 40 C-4, Florida Administrative Code.<br />
