Environmental Issues Related to Site Development

Stabilization of Denuded Areas for Fall and Winter

In order to prevent soil erosion and reduce silt from entering our streams and rivers, you are required to stabilize all denuded areas as soon as the final grades are reached, or when these areas will be left denuded for 14 days or more.

The Design and Construction Standards Manual (DCSM) Section 751.01 (I) requires that "Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grading is reached on any portion of the site.  Temporary soil stabilization shall be applied within seven (7) days to denuded areas that may not be at final grade but will remain dormant for longer than fourteen (14) days, except for that portion of the site on which work will be continuous beyond fourteen (14) days.  Permanent soil stabilization shall be applied to areas that are to be left dormant for more than six (6) months.  For winter stabilization, any area denuded for more than fourteen (14) days after November 1 and before March 1 shall be mulched and seeded appropriate to the season and site conditions.  Preparation of areas for permanent stabilization shall be performed in accordance with standard specification #3.32 of the Virginia Erosion and Sediment Control Handbook and per the Erosion and Sediment Control Law, Title 62.1, Chapter 3.1, Article 2.4 of the Code of Virginia."

Following these regulations will save your money and will protect our streams.

If you have any questions, please contact the Watershed Management Branch at (703)792-7070.  Please note that our inspectors will strictly enforce these regulations.
