West Virgina Department of Environmental Protection recently released the Stormwater Management and Design
Guidance Manual. You can download the entire manual from this website. This manual provides design and
guidance on designing and implementing stormwater management practices that will manage rainfall on site in
accordance with West Virginia's small Municipal Separate Storm Sewer System (MS4) general permit.
This manual contains stormwater management practices that utilize the Runoff Reduction Method, which is a
method that utilizes infiltration, harvesting and evapotranspiration of rainfall on site. For more
information about the runoff reduction method see the Additiona Information section.
