Mendocino County Operators and Riggers: Study Remotely

Potter Valley: a dam removal in the planning stage

PG&E's Potter Valley Project diverts Eel River water through a tunnel into the Russian River basin. After deciding not to relicense it, PG&E filed its final license surrender application and decommissioning plan with federal regulators in July 2025. The plan proposes removing Scott Dam, a 138-foot dam that forms Lake Pillsbury in Lake County, and the 63-foot Cape Horn Dam, with a new diversion facility to keep some water moving to the Russian River.

In 2026 FERC opened scoping for its environmental review and the U.S. Department of Agriculture intervened in the case, so the outcome is still open; PG&E has said removal could begin as early as 2028. If it goes ahead, dam removal, a new intake and river restoration would bring heavy civil crane work to a remote corner of the county for years.

Timber, highways and lines

• Mills and log yards around Ukiah, Willits and the coast need cranes for saw replacements, kiln and boiler work and conveyor sections. A mobile crane operator course plus rigging study fits that work.
• Caltrans repairs on U.S. 101, Route 20 and coastal Route 1 deal with slides, culverts and bridges, often on single-lane closures. Signal person training helps the whole crew.
• Utility hardening across fire-prone ridges keeps line crews setting poles. Study digger derrick operator content and know which equipment falls under the High Voltage Electrical Safety Orders.
• Wineries and agriculture in Anderson Valley and around Hopland add tank sets and processing equipment for articulating crane operator units.

Terrain and weather that change the plan

Much of the county is mountains, and the roads follow canyons. A crane mobilization from Ukiah to the coast on Route 20 means grades, curves and limited turnouts. Winter brings heavy rain on the coast range, saturated ground and landslides; summer brings inland heat and wildfire smoke. On the coast, salt air and wind off the Pacific add their own limits. Ground-bearing checks, cribbing and wind decisions get practical fast.

The Willits Bypass, which opened in 2016, gave U.S. 101 a new route around downtown Willits on a long viaduct, and it is a reminder of how big highway jobs can still land in a rural county. When they do, contractors often bring operators from outside the area unless local hands already hold the right certificates.

Certification without a local office

There is no Mendocino County crane license, and you do not need to visit a state office. California handles operator qualification through Title 8: covered mobile and tower cranes must be run by an operator certified, for that type of crane, by an accredited certifying body. The written test can often be taken through online proctoring; the practical always happens in person. The requirements guide has the full list of steps.

Small crews can study together even when they are spread from Gualala to Covelo, since everyone works through the same lessons and practice questions on their own device.
