NID moves forward on Combie Canal project

The Nevada Irrigation District is moving forward with a multi-million-dollar project that will significantly improve the main canal system that supplies NID service areas in Placer County.

The NID Board of Directors on Wednesday approved a $370,980 engineering services contract with Stantec Consulting Services Inc., an international firm with an office in Nevada City.

Under the contract, Stantec will design the replacement of the Bear River Siphon, which crosses the Bear River and carries water from NID’s Combie Phase I Canal into Placer County.

NID Engineering Manager Gary King said the upgrade of 9,100 feet of the canal is being designed separately by NID staff.

King said the aging canal, which runs from Combie Reservoir through the steep Bear River canyon, is a key NID facility, carrying nearly two-thirds of the water supplied by the district.

The canal is a source for NID’s North Auburn and Lake of The Pines water treatment plants.

The overall project, titled the Combie Phase I Canal and Bear River Siphon Replacement, is estimated at $20 million. The district is planning a bond issue to finance the work.

In other business, directors:

— approved a $250,000 task order with consultants AECOM for subsurface investigations at the proposed Centennial Reservoir site on the Bear River.

The firm is providing geotechnical services for the district as part of the reservoir planning process.

— reviewed environmental studies and authorized NID Recreation Manager Peggy Davidson to move forward on Phase II of the Scotts Flat Lake Trail, which will be constructed by the Forest Trails Alliance.

The first phase of the hiking and biking trail was built two years ago and runs from the Pioneer Trail near Highway 20 near the Five Mile House, to NID’s campgrounds at the lake.

Phase II includes three looped trails on the north side of the reservoir and a trail to Cascade Shores. Construction is planned in 2016.

The next regular meeting of the NID Board of Directors will be held at 9 a.m. on Oct. 28 at the NID Business Center in Grass Valley. NID board meetings are open to the public.
