Sonoma County and the North Bay would benefit from the increased investment in public works contained in Gov. Jerry Brown's $150 billion proposed budget unveiled last month.

Accompanying the Democratic governor's spending blueprint is a five-year capital project spending plan — the first since 2008.

Although $53 billion of the $57 billion earmarked between now and 2019 would be devoted to streets, roads, highways and high-speed rail, the plan specifically mentions improvements to the state hospital in Napa and the Veterans Home in Yountville.

Other capital needs at North Bay state parks and other facilities could also be included once the plan is finalized.

Brown also sets aside an additional $815 million in one-time funds for the fiscal year that begins July 1 for deferred maintenance projects, which has lagged during the state's cash-starved budgets of the past decade.

"It's important to focus attention on the infrastructure we've got to make sure it has the longest useful life possible, which helps reduce the need to build more expensive new facilities," said H.D. Palmer, spokesman for the state Department of Finance.

The $815 million includes everything from overpasses and border checkpoints to classrooms and armories. Like Brown's five-year public works plan, the bulk of the deferred maintenance money — $337 million — is spent on the state's transportation system.

Of that money, $100 million would be sent to cities and counties for street and road maintenance and repairs. The State Controller estimates that Sonoma County would get nearly $840,000 under the various formulas used to divvy up the money. Napa County would receive $285,000 and Lake and Mendocino counties would get $185,000 and $253,000, respectively. Santa Rosa would receive $260,000.

The governor's five-year capital plan mirrors the multi-year spending plans adopted by the state Transportation Commission in 2012. Brown's plan also doesn't affect local transportation project priorities established through half-cent sales tax increases like Measure M, adopted by Sonoma County voters in 2004.

Among the $90 million in projects Sonoma County lists on the proposed State Highway Operation and Protection Program for 2014 are:

— $32.5 million to realign Highway 1 near Carmet, slated to start in the fiscal year beginning July 1, 2015.

— $11 million to protect against landslides on Highway 1 near Fort Ross, also slated for the 2015 fiscal year.

Other big-ticket items in Brown's budget include the new $179 million courthouse in Santa Rosa. Construction of the 173,500-square-foot facility is scheduled for the fiscal year beginning July 1, 2016 with completion in the early part of 2019. Brown's budget proposes spending $7.7 million to create preliminary plans for the 15-courtroom project.

On a similar track is a new courthouse in Ukiah. The $122 million project is also scheduled for completion in early 2019. The governor's budget proposes spending $4.5 million to create preliminary plans for the nine-courtroom project.

A four-courtroom courthouse in Lake County is further along. The governor's budget contains $3.5 million to generate working drawings, the step preceding construction. The $55 million project is slated for completion in the fall of 2017.

No North Bay projects for the California Highway Patrol, the Department of Motor Vehicles or Cal Fire are identified in the governor's five-year capital outlay plan.

The Department of Parks and Recreation, which says it has a statewide deferred maintenance backlog of $1.5 billion, would receive $131 million under Brown's plan. The money is designed to address critical health and safety issues, enhance day-use facilities, and preserve and restore cultural and historic resources.

In the budget Brown unveiled in January is an additional $40 million for the parks department's most critical deferred maintenance.

"We are still working on prioritizing the projects," said Vicky Waters, a spokeswoman for the department.

Napa State Hospital, opened in 1875, would receive about $40 million under Brown's plan over five years for various building renovations, including $2.2 million for security fencing, $5 million for a recycled water system and $31 million for renovations.

Brown also proposed spending $6.5 million to improve the electrical and telecommunications systems at the Yountville veterans home and expand its pharmacy.

"Aging infrastructure and inadequate housing units at Yountville are the key drivers of CalVet's capital outlay needs," the Democratic governor says in his plan.
