Flood Mitigation Plan

On July 30, 2024, the Board of County Commissioners of Calvert County adopted an updated flood mitigation plan as an appendix to the County's 2023 all-hazard mitigation plan. An updated high tide flood mitigation plan was approved on September 9, 2025. Under the Disaster Mitigation Act of 2000, communities with pre-disaster mitigation plans may access post-disaster funding. Both flood mitigation plans are found in the appendices, below:

Historically, some communities created their own flood plans. Two were adopted: Cove Point (2014) and Broomes Island (2016).

Approximately 11% of Calvert County is within the Special Flood Hazard Area.

National Flood Insurance Program (NFIP)

Calvert County participates in a federal insurance program that offers reduced flood insurance rates and disaster funding in return for Calvert proactively reducing flooding risks. Calvert County does this through zoning regulations and public education. FEMA periodically updates Flood Insurance Rate Maps and Calvert’s were last updated in 2013; digital FIRMs are available here and delineate Calvert County into different flood-risk zones, including the Special Flood Hazard Area.
