Spatial Data

InfoTechIconGIS_TopoPublic Works Agency shares GIS (Geographic Information System) files and other spatial data upon request. Our technical divisions within Public Works dedicate a substantial amount of effort toward strategic implementation of Information and Technology on behalf of the Agency.  We often share data and resources with collaborating stakeholders.

Although all departments in Public Works are subject to the California Public Records Act, and do share data when appropriate, Watershed Protection District receives numerous requests.
