Document Description
The California Department of Fish and Wildlife has Notification of Lake or Streambed
Alteration, EPIMS Notification No. EPIMS-MEN-17140-R1C, pursuant to Section 1602 of the Fish and Game Code to the Mendocino County Department of Transportation.
The Permittee proposes to replace an existing corrugated metal pipe (CMP) culvert will with a 40’ x 36” reinforced concrete pipe (RCP). The diameter of the new pipe was sized to pass the peak discharge of the 100-year storm event for the associated watershed. A trench will be excavated across the road to expose the full length of the
existing pipe. The existing pipe will be removed as well as the flume structure beyond the outlet. The new pipe will be installed and backfilled with compacted Class II aggregate base. Due to possible scour at the outlet, energy dissipaters will be constructed. Dissipaters will consist of a 12’L x 14’W rock slope protection (RSP) outlet apron. An 8’ high concrete headwall will be installed at the outlet and at the inlet to prevent erosion and future damage.
