Martis Valley Trail is a paved, multi-use recreational trail, that connects the communities of Truckee and Northstar, and ultimately the Lake Tahoe Basin. The 9+ mile trail begins near the southern limits of the Town of Truckee, crosses through Martis Valley, and ends near Sawmill Flat Reservoir at a junction with Forest Route 73 (AKA the Fiberboard Freeway), allowing connection to Tahoe’s north shore. AEC worked with the environmental consultant to complete an equal-weight CEQA analysis of two project alternatives. Multiple resource areas required bridge/boardwalk crossing evaluations to minimize impacts.

The project replaces an existing 2,500 LF small diameter tank line from the Four Season water tank to the Tahoe Woods Subdivision with 12″ tank line to provide fire flows that comply with the California Fire Code. The new line also provided electrical service to the water tank to enable the TCPUD to remotely monitor the water level inside the tank. Special considerations in this project include close coordination with the USFS. The water tank and waterlines are on USFS land acquired through the Burton Santini Act. A USFS Special Use Permit, including specific resources documentation and analysis as well as proper legal privilege was needed from the USFS and the Tahoe Woods Subdivision.

The project included the replacement of the entire 36-inch sewer main pipeline as it crosses the Truckee River in Tahoe City, CA. AEC completed the surveying and base mapping required for design and permitting for the project. Survey services included topographic and boundary surveys, location of physical features in the Truckee River channel, and depiction of 100-year floodplain limits. Permits required for the project include a US Forest Service Special Use Permit, a California 401 Water Quality Certification and Basin Plan Exemption, a CA Department of Fish and Wildlife Streambed Alteration Agreement, and Caltrans Encroachment Permit for construction staging and access within the Caltrans Maintenance Yard.
