Document Description
The Metropolitan proposes to install two culverts at Service Connection SD-2, located along the access road for the San Diego Pipeline Nos. 4 and 5. Metropolitan proposes to install two 18-inch diameter culvert pipes at an existing paved road crossing at Rainbow Creek to convey creek flows beyond the road crossing to the natural drainage downstream. The pipes would be held in place by six-inch minus rock concrete slurry and a constructed headwall and tail-wall at the upstream and downstream edges of the crossing, respectively. Within the road crossing, the pipes would be covered with suitable road base material consisting of gravel and sand. In order to install the culverts, Metropolitan proposes to remove accumulated sediments and vegetation from the project area.
