An amendment to Virginia's Stormwater Management Act was adopted to implement a tiered approach to stormwater management for rural Tidewater localities. To participate a locality is required to have a map showing the boundaries of the locality, with each watershed located partially or wholly within the locality, and the percentage of impervious cover (cover that impedes the natural infiltration of water into the soil) within each watershed. Center staff created maps indicating the initial percent of existing impervious cover present in each watershed for the Middle Peninsula Planning District (MPPDC) localities; Gloucester, Essex, King and Queen, King William, Mathews, Middlesex Counties and the Town of West Point. The watershed maps created illustrate the percent of impervious cover at the start of the tiered stormwater program; the localities are responsible for tracking any additional impervious area going forward.
