In support of the Contra Costa County’s “Shelter in Place” Order and the Governor’s Executive Order, the Contra Costa Transportation Authority shifted to a “virtual office” effective Friday, March 20, 2020. We plan to work remotely unless the order is rescinded or amended.
All staff are working remotely and may not have regular access to mail, office deliveries, and their work phone lines, so please also send correspondence and communications via email. Please visit our Public Meetings webpage to view the latest meeting notices and options for participation.
