Box Canyon Manhole and Road Improvement Project

The Box Canyon Manhole and Road Improvement Project is an infrastructure initiative managed by the City of Thousand Oaks Public Works Department in Ventura County, California. The project focuses on enhancing the reliability of the city's wastewater conveyance system and improving long-term access for maintenance vehicles along the Box Canyon access road. Key technical deliverables include the installation of a new manhole and the replacement of approximately ten feet of existing eight-inch diameter asbestos cement wastewater piping. Additionally, the project involves the concrete paving of approximately 260 linear feet of the existing steep unpaved access road to ensure stable, year-round accessibility. To manage stormwater and erosion, the scope includes the installation of five new 18-inch storm drain pipelines with upstream and downstream headwalls, as well as the construction of three additional upstream headwalls for existing culverts. The project is classified under NAICS code 237310 and has been certified as having no significant environmental effect through a Negative Declaration pursuant to CEQA. Administrative oversight is provided by Patrick McCulloch, the Utilities Maintenance Supervisor, with the project located in Thousand Oaks, California, zip code 91360.
