Document Description
The project is limited to one encroachment. Humboldt Community Services District proposes replacing the water main serving Tower Drive. Replacement requires digging a 5.5-foot-deep trench through an existing stream crossing. Work for this encroachment will include excavation, removal of the existing water main, replacement with a new water main, backfilling with pea rock, and resurfacing the crossing. A cofferdam shall be installed above the culvert inlet to isolate and dewater the work site and minimize the risk of streamflow entering the excavated trench. Flowing water shall be cleanly bypassed and/or prevented from entering
the work area through pumping or gravity flow, and cleanly returned to the stream below the culvert outlet. Normal flow shall be restored following completion of the work in the vicinity of the stream. Should damage to the culvert occur, Permittee shall immediately notify CDFW and make any necessary repairs.
