With the costs of storm hazard insurance on the rise, there has been increased scrutiny by communities, developers and property owners on FEMA Flood Insurance Rate Maps (FIRMS). This is especially true in the coastal VE Flood Zones where insurance premiums may represent a significant portion of annual expenditures. Because FEMA's flood zone mapping and remapping efforts are performed on a large scale (nationwide, by county), they may not accurately represent a client's property.

ATM has proven experience in evaluating FEMA flood insurance studies (FIS), FIRMs, and accurately identifying flood hazards. We provide flood zone remapping services via the FEMA Letter of Map Change (LOMC) process –resulting in substantial savings on flood insurance. ATM's knowledge of insurance reforms, including Biggert-Waters Flood Insurance Reform Act of 2012 and Homeowner Flood Insurance Affordability Act, allow us to advise our clients accordingly.

ATM offers a variety of flood zone solutions tailored to each client's specific needs. Efforts range from review of flood maps and zones to detailed numerical modeling of storm surge, waves, and coastal inundation. Structural alternatives are also available, such as seawall or trip wall construction and reinforcement. ATM's coastal engineers perform detailed analyses and produce the technical submittals required to obtain the Letter of Map Revision (LOMR) or Letter of Map Amendment (LOMA) from FEMA.

ATM's primary geographic focus is in the Southeastern U.S., the U.S.V.I. and Puerto Rico. We have professional engineers licensed in multiple states and also provide customized coastal flood hazard assessments and mapping throughout the Caribbean region and internationally, where reliable flood hazard mapping data often does not exist.
