About this file
This document is a utility and potholing report prepared by C Below Subsurface Imaging for the Thousand Oaks Solar Canopies Project located at 1993 Rancho Conejo Blvd. in Thousand Oaks, California. The report details six pothole locations and one dry hole, systematically documenting underground utility mapping for a municipal service center microgrid project. Each pothole was meticulously examined and recorded with specific details including utility type (predominantly gas and water lines), pipe material (primarily PVC), pipe size, depth, and directional orientation. The locations were all situated around a CNG fuel station, with pothole depths ranging from approximately 2.82 to 4.46 feet and pipe sizes varying from 1 to 8 inches.
The utility investigation was conducted on December 4th, 2017, by technician Fernando Mendoza, with the project number 16-0746. The potholing report includes comprehensive documentation for each location, featuring detailed data sheets, physical swing tie information, hand sketches, and photographic evidence. The utilities discovered were primarily 2-inch and 8-inch PVC pipes for gas and water lines, with one location yielding an unknown utility potentially related to a fire alarm system. The surface material at all locations was asphalt, and the investigation was performed to support the upcoming municipal service center microgrid and backup power infrastructure project.
