RE: (VA10K902) - Birnam Woods E&SC Exhibit
1 am requesting a variance to the Minimum Standards of the Erosion & Sediment
Control Handbook In order to reduce the overall impacts of disturbance the applicant is
requesting the use of modified mud traps as indicated on the E&SC and SWM Modification
Plan for Birnam Woods. These mud traps will allow the contractor to capture concentrated
water that will be generated from fill slopes tying into existing grade. The drainage areas
behind these mud traps are small so the flow should be minimal giving the designer
confidence in their application here. Traditional sediment traps would push the limits of
disturbance further out than necessary. If, during construction, the county E&SC inspector
deems these measures to be inadequate, the contractor will provide additional measures to
the satisfaction of the inspector. Please let me know if you have any questions or concerns.
