Stafford County, VA Environmental Rules: Stormwater Management (2026)

5 of the county's Virginia Erosion and Stormwater Management Program spells out what a stormwater management plan must do: it applies the technical criteria in Part V of the state regulation (9VAC25-875) to the entire land-disturbing activity, and individual lots inside a new residential, commercial, or industrial development, even lots sold to a later owner, cannot be treated as separate projects for compliance purposes. The plan has to account for every source of surface runoff plus subsurface and groundwater flows that get converted into surface runoff.

A complete submission needs background information on discharge points, owner and parcel contact details, a site condition narrative, a description of the proposed stormwater facilities, hydrologic and hydraulic computations built to the Stafford County Stormwater Management Design Manual, a topographic site map showing drainage areas, floodplains, and FEMA panel references, and, where the operator plans to buy nutrient credits, a letter of availability from the offsite provider. Plans requiring a professional license must carry the seal of a Virginia-licensed engineer, architect, landscape architect or land surveyor.

For smaller residential work, such as accessory structures, sidewalks, pools or patios disturbing between 2,500 and 10,000 square feet that add no more than 10 percent impervious cover and need no water-quality controls, a licensed professional may certify a simplified plan instead. 00 for construction disturbing 100 acres or more, under Table 1 of Section 11-16.
