Document Description
Proposed project would repair an access road along Adobe Creek. To accomplish this, an existing corrugated steel pipe running beneath the access road will be replaced with a reinforced concrete pipe and fill placed on top of the pipe to restore use of the road. The pipe carries stormwater from an inlet located in a stormwater swale that captures runoff from a parking lot. In addition, the new pipe will be 28 ft longer thereby extending the pipe through riparian habitat and into Adobe Creek. The existing concrete apron will be broken up to allow the new pipe to sit at the correct elevation to maintain flow, and the area will be re-graded and partially rocked to provide energy dissipation to prevent erosion of the bank.
