Learn about best management practices for stormwater runoff using permeable paving solutions.
In a natural woodland or meadow, very little rainfall runs off. During development, natural vegetation is usually removed and replaced with hard impervious surfaces such as roads, buildings and parking areas. This land surface change decreases infiltration, groundwater recharge and evapotranspiration; increases runoff and carries excess nutrients, sediment and other contaminants into our waters.
In order to protect citizens, property and natural resources from unmanaged stormwater runoff, the Virginia stormwater act and VSMP permit regulations (effective Sept. 13, 2011) now provide the ability to manage the quantity and quality of stormwater runoff on a construction site as well as on aregional or watershed basis.
