Document Description
The Project involves infrastructure upgrades and maintenance activities along the Box Canyon access road, which serves as a critical component of the City of Thousand Oaks Public Works Department wastewater conveyance system. The purpose of the Project is to improve long-term access for maintenance vehicles, improve side canyon drainage transport across the access road, and ensure the continued reliability of the City's wastewater infrastructure. Proposed improvements include the installation of a new manhole and replacement of approximately ten (10) feet of existing asbestos cement (AC) eight (8) - inch diameter wastewater piping at the proposed manhole structure to facilitate maintenance and inspection of the wastewater system, and the concrete paving of approximately 260 linear feet of roadway segment of the existing, steep unpaved access road to provide stable, year-round access. To address stormwater management and erosion control, the Project also includes the installation of five (5) new 18-inch storm drain pipelines across the unpaved access road, each with upstream and downstream headwalls, as well as the construction of three (3) additional upstream headwalls for three (3) existing storm drain culverts.
