DNREC and the federal government are working on an update of the floodplain maps for Bundicks Branch, located west of Lewes, in Sussex County. The study involves new data and engineering models. The floodplain map update will occur through a process called a Letter of Map Revision (LOMR).
DNREC gathered input on the project from residents and property owners during the summer of 2021. A consultant has developed a proposed update to the Bundicks Branch floodplain mapping for review by FEMA.

Floodplain mapping for Bundicks Branch will be revised through a FEMA process called a Letter of Map Revision (LOMR). Revising a floodplain map involves data analysis and modeling. New mapping is developed using topographic data along with engineering models.
The current Bundicks Branch floodplain mapping was generated using approximate modeling methods. The updated mapping will involve more detailed modeling methods and will include base flood elevations. Base Flood Elevations are estimated 1 percent annual chance flood elevations (also known as 100-year flood elevations).
The study area and the current floodplain mapping are shown below. Proposed new floodplain map areas have been developed and are available for public review. The proposed floodplain mapping is under review by FEMA and may be revised as part of that review process.
Homeowners insurance does not cover flood damage. Flood insurance in available through the National Flood Insurance Program (NFIP).
Homes that are within Special Flood Hazard Areas that have federally-backed mortgages must purchase flood insurance. Changes to the Bundicks Branch floodplain maps may have flood insurance implications for local homeowners.
Owners of homes newly mapped into the floodplain may have to buy flood insurance once the map changes go into effect. Some may find their homes no longer in the mapped floodplain. They may be eligible for lower cost flood insurance.
