Revised flood zone maps for areas south of route one released

The revised flood zone maps for areas south of route one are based on data from 1988 to 2008 and will potentially move 11 properties from the high risk zone to the low/moderate risk zone.  However, the revised maps will move 123 properties from the low risk zone to a high risk zone.

To check how the new maps affect your property, visit the Town of Charlestown web site.   On this page a link to download Google Earth, required to view the maps, precedes those for the existing and new FEMA flood zones. To determine whether your zone has changed, enter your street number and name.  Move the cursor to the side of the marker for your property, and you will see the elevation on the respective maps.

Property owners who question the revised maps may contract with an independent surveyor and provide data to FEMA that shows the maps to be scientifically or technically incorrect by November 8, 2012.   Owners or property associations may request a Letter of Map Amendment or a Letter of Map Revisions by calling 1-877-336-2627.

Jessica Stimson, floodplain mapping coordinator for the Rhode Island Emergency Management Agency, offered Charlestown residents the opportunity to ask questions about the revisions on Thursday evening, September 20.  She said, “The revisions were created with the latest technology and reflect a more accurate assessment of risk.”  Her email is jessica.r.stemson@us.army.mil.

Charlestown’s Building and Zoning Official, Joseph L. Warner Jr., and Charlestown Emergency Management Director Kevin R. Gallup responded to questions and offered their expertise about the specifics of Charlestown.  Charlestown’s GIS Specialist Stephen McCandless demonstrated the use overlays on the projector and found individual properties in the various zones.  The maps are available for viewing in the Building/Zoning Department of Town Hall, as well as on the web site.

FEMA is also revising maps for the flood zones north of route one and estimate those revisions will be out in 2015 and will most likely include the 2010 flood.
