Stormwater Management Plans, or SWMPs, are comprehensive studies that examine the linkages between drainage servicing, land use planning and environmental protection. Their purpose is to support the growth of a community in a way that maintains or ideally enhances the overall health of a watershed. As such, the SWMP can be a powerful tool that enables a municipality to set a clear direction for the future of their community. All new developments including single family, duplexes, triplexes and any larger developments must prepare a stormwater management plan. BMP Engineering & Inspection Inc. makes the Stormwater Management Plan (SWMP) to help manage the rainfall, address water quality and quantity issues from stormwater runoff, and enhance the watersheds around the properties.
