Stormwater Pollution Prevention
Stormwater runoff is generated from rain events that flow over land or impervious surfaces, such as paved streets, parking lots and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams and lakes. Pollutants cause changes in hydrology and water quality that result in habitat modification and loss, increased flooding, decreased aquatic biological diversity, and increased sedimentation and erosion. To protect these resources, municipalities, construction and industries activities use stormwater controls, known as best management practices (BMPs), to manage their runoff.
The benefits of effective stormwater runoff management can include:
- protection of wetlands and aquatic ecosystems,
- improved quality of receiving waterbodies,
- conservation of water resources,
- protection of public health, and
- flood control.
The public can take action in the Stormwater Pollution Prevention by avoiding hazardous practices and reporting illicit discharges and improper waste disposals found.

Determining the Risk
To identify a community’s flood risk, FEMA conducts a Flood Insurance Study. The study includes statistical data for river flow, storm tides, hydrologic/hydraulic analyses, and rainfall and topographic surveys. FEMA uses this data to create the flood hazard maps that outline your community’s different flood risk areas. Floodplains and areas subject to coastal storm surge are shown as high-risk areas or Special Flood Hazard Areas (SFHAs). Some parts of floodplains may experience frequent flooding while others are only affected by severe storms. However, areas directly outside of these high-risk areas may also find themselves at considerable risk. Understanding Your Area Changing weather patterns, erosion, and development can affect floodplain boundaries. FEMA is currently updating and modernizing the nations Flood Insurance Rate Maps. These digital flood hazard maps provide an official depiction of flood hazards for each community and for properties located within it. FEMA has published almost 100,000 individual Flood Insurance Rate Maps. See your map and learn how to read it so you can make informed decisions about protecting your property, both financially and structurally.
