WHY CONSIDER SVCS?
The transportation sector is the largest emitter a
of greenhouse gases in California.
Contra Costa County is in the top 10 counties
in California for highest number of electric
vehicles (EVs) registered.
Six Central San employees currently drive EVs.
This is an opportunity for Central San to
demonstrate its environmental leadership.
There is grant funding available to assist.

PROJECT UPDATE
Staff completed and submitted the Air District grant application
in June 2019.
Staff created a contingency capital project (DP 8252) and
issued a task order to TJC and Associates, Inc. (TJC) to
complete a 30% pre-design and cost estimate for EVCS
installation in the Plant Operations Department's parking lot.
TJC's report is currently being finalized.

PROJECT UPDATE
• Central San will be eligible to apply for grant funds from the
Air District in Spring 2020, when the Air District's grant
program reopens. This program provides $4,000 in grant
funding per dual-port Level 2 EVCS and $18,000 in grant
funding per Level 3 EVCS.
