2253 [30 JANUARY 2009]
Town of Sullivan’s Island, SC
The lines are scheduled for updating in 2009 (WC Eiser, OCRM, pers comm, Dec 2008). In
the case of Sullivan’s Island, the lines are well seaward of existing development along the AL
study area. However, at Breach Inlet, the lines encroach certain properties because of prior
shoreline positions, erosion, or limited beach and dune width. An implication of the develop-
ment control lines for the ALMP is that certain activities may be allowed, without state permit,
landward of the setback line. This could potentially include alterations to vegetation and
topography for the benefit of the community, enhanced storm-surge protection, fire control, or
public access and safety.
National Flood Insurance Program (NFIP)
The National Flood Insurance Act of 1968 established the NFIP, enabling property owners in
participating communities to purchase flood insurance along the coast. Sullivan’s Island
participates in the NFIP and enforces NFIP regulations through their locally adopted flood
ordinances. The Federal Emergency Management Administration (FEMA) administers the
NFIP and establishes the technical basis and controlling elevations for development under the
program. Among the regulations of the NFIP, first-floor elevations of habitable structures must
be constructed at or above the 100-year base flood elevation (BFE). Along the open coast,
an additional component (the action of waves) is incorporated into the building requirements
for habitable structures via V-zone flood boundaries. [Note: A summary of the NFIP can be
found at http://www.fema.gov/about/programs/nfip/index.shtm.]
Because of its importance to Sullivan’s Island, a part of the ALMP relates to a review of
impacts to flood levels and wave hazards under existing and anticipated future conditions by
means of state-of-the-art models developed by FEMA.

dix 2 of this report. Among the deed restrictions are:
