Stormwater Management for Construction & Development
Erosion & Sediment Control Program
The City of Danville is required by the Department of Environmental Quality (DEQ) to implement an Erosion and Sediment Control (DEQ) Program. The DEQ Program's goal is to control soil erosion, sedimentation, and non-agricultural runoff from regulated land-disturbing activities to prevent degradation of property and natural resources. The regulations specify minimum standards (including criteria, techniques and policies) which must be followed on all regulated activities. This program utilizes a Land Disturbance Permit to regulate these land disturbing activities. To learn more about the Land Disturbance Permit, please visit our Engineering Permits page.
Virginia Stormwater Management Program (VSMP)
The City of Danville is required by the Department of Environmental Quality (DEQ) to implement the Virginia Stormwater Management Program (VSMP). This program includes administration of the VSMP Permit for General Construction activities. The purpose of this permit is to regulate development activities, provide for requirements relating to the management of stormwater during construction activities and management of water quantity and water quality of the developed project. To learn more about the VSMP Permit, please visit our Engineering Permits page.
The VSMP also requires the establishment of a Best Management Practice (BMP) inspection program. BMPs are permanent stormwater controls that are installed during development to manage stormwater quality and quantity from the developed site. The purpose of the BMP inspection program is to ensure proper maintenance and continued functionally of the permanent stormwater controls.
Low Impact Development
Pervious areas, such as grassed or landscaped areas, allow for the infiltration of rainwater. Impervious areas, such as asphalt, concrete and buildings, do not allow for the infiltration of rainwater. Standard commercial and residential development increases impervious areas which in turn increase the amount of runoff that is generated during a rainfall event. This could result in downstream flooding or accelerated channel erosion. Not only do impervious areas increase the amount of stormwater runoff, they also increase the amount of pollutants found with that stormwater runoff. When it rains, stormwater picks up these pollutants and carries them through a storm drain system directly to local creeks, streams and rivers. This can create water quality problems with these watercourses. Water quality problems result in restrictions and mandates for local government which ultimately places burdens on future development projects and future businesses, existing businesses and residents.
Have you considered Low Impact Development?
Low Impact Development (LID) can help minimize the effect that development has on the environment. LID is an environmentally friendly approach to development of a site. This approach helps conserve natural systems and hydraulic functions on a site. LID can help filter stormwater onsite to remove pollutants before it is released into the environment. LID can also store stormwater onsite which can reduce downstream flooding and channel erosion. LID can be incorporated into a development design or into an existing development. Examples of LID include Grassed Swales, Permeable Pavers, Rain Barrels, Rain Gardens, and Green Ponds.
