Boschert Creek Levee Study

The agricultural levee adjacent to Boschert Creek between Boschertown Road and New Town Blvd. was de-certified in 2009. Until this time, it was shown on the effective Flood Insurance Rate Map (FIRM) as providing protection to the adjoining properties.  When the FIRM was revised in 2010 and the preliminary DFIRM published, it showed parts of Charlestowne and the commercial area south of the creek in the floodplain.

FEMA is now proceeding with the Final Levee Analysis and Mapping Procedure (LAMP), which will determine the flood risk and generate the DFIRM for the secluded area. It is anticipated that 853 residences and 74 commercial properties will be mapped into the flood hazard area and be required to obtain flood insurance.

The Department of Engineering has meeting with property owners regarding the Boschert Creek Levee Study. The following presentation has been given during these meetings: Boschert Creek Presentation


The next presentation will be for residents of Charlestowne Plat 1.
