Public Notice:

Proposed Flood Hazard Determinations

Appeal Period begins August 15, 2017 and ends on November 12, 2017

On December 28, 2016 and June 15, 2017, the Federal Emergency Management Agency (FEMA) provided New Castle County with Preliminary and revised Preliminary copies of the revised Flood Insurance Rate Maps (FIRM) and Flood Insurance Study (FIS) report for New Castle County, Delaware and Incorporated Areas.  Digital copies of these materials are available at .  A searchable map, where you can enter your tax parcel identification number or address is also available at .

Notice of the proposed flood hazard determinations were published by FEMA in The News Journal on August 8, 2017 and August 15, 2017.

The proposed flood hazard determinations, if finalized, will become the basis for the floodplain management measures in New Castle County.  However, before any new or modified flood hazard information becomes effective, a 90 day appeal period is available to communities and citizens.  The appeal period begins on August 15, 2017 and ends on November 12, 2017.

During the 90-day appeal period, any owner or lessee of real property who believes his or her property rights will be adversely affected by the proposed flood hazard determinations may appeal to New Castle County.  New Castle County will forward appeals it receives within the 90 day appeal period to FEMA.  It is important to note, however, that the sole basis for appeals is the possession of knowledge or information indicating that the proposed flood hazard determinations are scientifically or technically incorrect.
