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.
The project included constructing approximately 1,679 lineal feet (LF) of 8-inch waterline, 143 LF of 4-inch waterline, 532 LF of 2-inch waterline, 5 fire hydrants, and 23 water service laterals. The project was necessary to improve fire hydrant spacing and fire flow rates in conformance with California Fire Code 2010 within the McKinney Tract and the Placer County ROW. The project included approval from Caltrans for an open cut trench for installation of the waterline in Highway 89 right-of-way.

The Martis Valley Trail (MVT) is part of a planned 62-mile trail network referred to as the “Resort Triangle.” Covering about 9 miles, the MVT section extends between Truckee and the Tahoe Basin. MVT is being completed in phases, all of which AEC has contributed to in various capacities. Our Planning, Surveying, and Engineering teams have provided background reviews, compliance assistance, surveys and mapping services, civil design, and several other services for this section of the multi-use trail.

The project replaces the 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 will also provide 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 is needed from the USFS and the Tahoe Woods Subdivision.
