Floodplain management is about reducing vulnerability to flood risk to our built environment. If we know low lying land will flood from time to time, we should make reasonable decisions to help protect our families, homes, and businesses.
Stormwater runoff is generated from rain and snowmelt that flow over land or surfaces such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The water drains along curbs and gutters into a network of pipes that eventually drain into streams, lakes, and rivers. The water picks up pollutants like trash, chemicals, oils, and dirt/sediment that contaminates water sources. To protect these resources, Merriam has a Stormwater Management Plan.
