OC Public Work's clients vary by each of our core businesses. As a whole, our clients comprise three groups:

Regional Client Services
Public Works serves all of Orange County by providing regional flood control, water quality enhancement, recreation, and agricultural services. These regional services are county-wide and are provided equally within city boundaries as well as in unincorporated areas. For most of these services our clientéle is the public at large. For example, everyone who lives or works in Orange County benefits from infrastructure that minimizes the threat of flooding. Property owners, businesses, and visitors all benefit and therefore are our clients, as are citizens in other counties through our involvement in cooperative projects with their local governments.

Municipal Client Services
For a second set of clients in unincorporated areas, we function as the OC Road and Flood division, providing local drainage, road construction, traffic and safety operations, weed abatement, street maintenance, land use, building permits, and building code enforcement, and related services. These duties are transferred to city government when an area is annexed by an adjacent city or is incorporated as a new city. The nature of our responsibilities changes from a regional and municipal service provider to a regional service provider only through the city formation process. In some cases these municipal services are retained through contracts with the new cities.

County Department Client Services
Our third set of clients is our internal customers, the other agencies and departments of the County of Orange. These are the clients to whom we provide office space and related environmental controls, utilities and transportation support.
