& Map Revisions
Coastal Systems International, Inc. has become widely
recognized as one of the nation's leading experts in
Federal Emergency Management Agency (FEMA) technical
analysis and regulatory interpretations. Our specialized
team utilizes historic, meteorologic, hydrologic, and
hydraulic data to interpret floodplain management regulations
and evaluate Special Flood Hazard Areas (SFHAs). FEMA
engineers and cartographers delineate SFHAs on Flood
Insurance Rate Maps (FIRMs). SFHAs are those areas subject
to inundation by a flood that has a one percent or greater
chance of being equaled or exceeded during any given
year. Coastal Systems reviews the design goals of a
project to provide information to the project developer
or architect relative to acceptable project design alternatives.
In addition, Coastal Systems provides services to obtain
variances from local floodplain ordinances, letters
of no obligation from FEMA, and processes revisions
to the SFHAs, as necessary, to meet project objectives.
Coastal Systems employs a variety of numerical modeling
applications to assist in the analysis and design of
project improvements and alternatives. Two modeling
applications employed specifically for FEMA interpretations
are the Wave Height Analysis for Flood Insurance Studies
(WHAFIS) model and the Wave Run-up Model, which determine
the height of run-up landward of the still water line.
Coastal Systems has successfully implemented both applications
on numerous projects requiring FEMA compliance interpretation
Coastal Systems' permitting and engineering team works
closely with attorneys, developers, architects, local
officials, FEMA representative consultants, and FEMA
officials to determine the most efficient and cost effective
design alternative for projects located within SFHAs.
