Rohnerville Air Attack Base Loading Pad and Lighting Project

Rohnerville Air Attack Base Loading Pad and Lighting Project

The Rohnerville Air Attack Base contains four loading pads. The concrete Loading Pads 3 and 4 have weathered due to the coastal environment and excessive use during emergency incidents. The surface is chipping and cracking, could cause aircraft damage, and could strain aircraft landing gear. The security and outdoor lighting at the loading pad area is inadequate and inefficient for current use. The proposed project would demolish the two concrete pads and replace them with reinforced concrete. AS part of the replacement, the pads will be expanded into the existing asphalt taxi lane replacement areas. It may be necessary to repair or replace the buried drainage pipes under the pads. Metal culvert drainage pipes were installed when the loading pads were constructed and may be rusted, or damage to the pipes may occur during demolition. The extent of the repair or replacement of the pipes is currently unknown and will be assessed following demolition of the loading pads. Excavation could be as deep as 12 feet into the fill material. Re-bedding of the drainage pipes will be accomplished by utilization of the excavated fill material. The existing asphalt taxi lane areas in the project area would be replaced with reinforced concrete. The dimensions of the asphalt replacement or concrete installation are approximately 200' x 400'. The proposed light installation will involve minor trenching and backfilling for the installation of a electrical conduit to power the new lights. Conduit installation will occur outside of the concrete installation in a ten-foot zone on the perimeter of the loading area. The lights are low profile and will extend less than three feet from ground level. No vegetation other than grass and forbs in the conduit installation area will be disturbed. A 100' x 100' spoils staging area will be utilized adjacent to existing Loading pad 1. The spoils staging area will be constructed on existing imported fill material. The spoils site will be graded and shaped for drainage following utilization. No vegetation other than grass and forbs in the spoils staging area will be disturbed.
