Flood Protection Plan
Community Flood Protection Plan
Flooding in Williamson County is a growing community problem. The Williamson County Office of Emergency Management has developed and implemented the Community Flood Protection Plan (CFPP) with other jurisdictions and stakeholders within the county and region. Reasons for developing a CFPP include but are not limited to:
- Frame a mitigation and preparedness plan to reduce flood risk within the county and region
- Flash floods can occur at any time during the year, but history has shown the late summer into fall and springtime to be the most prevalent and destructive
- After a significant wildfire, vegetation is lost, and soils can harden to repel rather than absorb water
- Form and maintain collaborative relationships with local stakeholders, emergency response personnel, and federal and state agencies BEFORE flooding occurs
- Develop and refine pre-attack strategies and plans to improve first responder readiness and safety
- Establish and document planning activities and identify projects within the scope of the grant
Williamson County is a participant in the National Flood Insurance Program (NFIP), which is based on an agreement between local communities and the federal government that states that if a community will adopt and enforce a floodplain management ordinance to reduce future flood risks to new construction in Special Flood Hazard Areas (SFHA), the federal government will make flood insurance available within the community as a financial protection against flood losses.
The Federal Emergency Management Agency's (FEMA) Flood Insurance, Rate Maps (FIRMs) are used to determine if properties are located within Special Flood Hazard Areas. The County provides map determination services upon request from residents, realtors, lenders, and insurance agents. The following GIS links show the locations of the SFHA, which are based on the most current FEMA Flood Insurance Rate Maps (FIRM):
In addition to protecting life and property, flood mitigation can also enhance first responder safety as well as protect at-risk populations, critical infrastructure, and natural resources.
Although proximity to public lands, such as wetlands, can impact flood risk, there are ways to minimize and reduce flood exposure from within the community as well. Focusing on local codes and ordinances, flood mitigation strategies, as well as flood reduction in parks, common-owned areas, and open spaces can greatly lower the risk and impacts of a flood.
