Flood zone maps being revised

March 21 18:30 2017 Print This Article

The Federal Emergency Management Agency (FEMA) is in the process of revising flood-zone risk maps for Charleston County. At a Tues. workshop at C.E. Williams Middle School, Charleston County employees advised property owners of their current flood risk status and the preliminary flood risk revision status. FEMA is expected to publish its new flood zone maps in late 2018 or early 2019.

Insurance agents were on-hand to advise property owners how a change in flood risk status would impact their flood insurance premiums. Property owners who have federally-backed mortgages who live in designated high-risk areas are required to purchase flood insurance.

The SC Dept. of Natural Resources manages the National Flood Insurance Program for the state and had representatives at the workshop. The revised flood maps are derived from improved technology for measuring the elevation of properties based on Global Positioning System (GPS) coordinates. The preliminary data indicates that 14,665 properties will be removed from the flood risk zones and that 3103 properties will be added. There are numerous properties not designated as high-risk which experienced flooding in 2015 and 2016.

There will be another flood risk workshop Wed. from 2-7 pm at Alhambra Hall, 131 Middle St. in Mt. Pleasant. You can access your preliminary flood risk status by calling FEMA at 877-336-2627.
