Office Locations

OC Public Works has facilities in three locations: The H.G. Osborne Building, Glassell Yard Offices, and the facilities on Fruit Street. We have provided 3 maps per location to illustrate surrounding streets, the section of the city, and freeway maps to guide you to your destination. You will also find information regarding the parking structures and availability as well as the hourly rates. The Civic Center map has been included to assist and orient you with the surrounding buildings and parking areas in downtown Santa Ana. Print out the maps that you need. We look forward to being of service to you.
