Upgrade and improve the water spigot drains in Portola Redwoods State Park to help reduce food subsidies available to wildlife. The project proposes to remove 38 existing wooden-framed rock drains, eliminate 14 drain locations, and install 24 new cement drains with fiberglass grates. At each work site, work will;
- Hand dig to remove existing wooden frames
- Use a backhoe with auger bit to excavate an approx. 60" to 70" deep by 36" wide hole;
- Place 12" to 24" of drain rock at the base of the hole:
- Use a back hoe and hand tools to install a 30" inch wide by 48" inch long cement pipe into the hole;
- Backfill the pipe and hole with additional drain rock;
- and Set a new fiberglass grate over the exposed end of the pipe
Project consists of the replacement of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced; the construction ans location of limited numbers of new, small facilities or structures; and the minor public or private alterations in the condition of land and/or vegetation that does not involve removal of healthy, mature, scenic trees.
