The Sonoma County Board of Supervisors has approved a new $9.95 million maintenance facility for the fleet operation that's being displaced by a new state courthouse, according to county records.

Supervisors kicked off the project by approving a $398,000 contract for San Francisco-based Kwan Henmi Architects to design the new facility, which would be built on a vacant 2.7-acre county-owned lot on Russell Avenue in Santa Rosa.

The new facility will be about 21,900 square feet with about 138 parking stalls. The fleet operation will maintain a separate motor pool for about 60 vehicles at a second central location at Ventura Avenue.

The county must relocate its fleet management division by April of 2016 to make room for the state's new $173 million courthouse.

The current facility houses Fleet Light Operations, Fleet Administration, and the Transportation and Public Works (TPW) Materials Lab. Fleet staff began searching for a potential relocation site in early 2011, before the state's courthouse was delayed by budget issues.

The county has identified six funding sources for the project, including $5.12 million from fleet property sales proceeds; $2.7 million from a fiscal-year 2015/2016 general fund appropriation; $900,000 in previously funded relocation monies; $328,000 in previously funded motor pool monies; and $100,000 from Fleet ACO.
