RE: Nystrom Driveway E&SC Plan
I 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 plan for Nystrom Driveway.
These mud traps will allow the contractor to capture concentrated water that will be generated
from cut/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 the 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.
