The Orange County OC Public Works provides for the planning, development, operation
and maintenance of public works in Orange County including those which are the responsibility
of the OCFCD.
OC Public Works will accomplish its Flood Control Program goals through an integrated
process under which we conduct feasibility, hydraulic, deficiency, floodplain and
value-engineering studies, collect and analyze data on an on-going basis, and design
and build projects. We also will respond to citizen concerns, flood emergencies
and operate and conduct our annual planned maintenance of flood control facilities.
We are additionally responsible for reviewing development proposals and providing
construction inspection services of developer’s construction projects.

Funding for projects of regional significance is provided by OCFCD primarily from
local property tax revenues. Under the provisions of Section 97 and 98 of the Revenue
and Taxation Code the property tax revenue is based on the average percentage received
during the three years prior to the passage of Proposition 13 in 1978 plus a proportionate
share of tax base growth. Subsequent to the passage of Proposition 13, State Special
District Augmentation funds have also been allocated to OCFCD by the Orange County
Board of Supervisors.


In addition to OCFCD projects, provides for implementation of a Local Drainage Program
to provide for construction of drainage facilities to correct localized flooding
problems in older parts of unincorporated Orange County . Funds for local drainage
projects in the unincorporated regions of Orange County are provided by the County
General Fund and Housing/Community Development funds.

The OCFCD program is developed with assistance from the City Engineers Flood Control
Advisory Committee (CEFCAC), a subcommittee of the League of California Cities,
Orange County Division.
OCFCD staff establishes and updates the multi-year Flood Control Project Plan annually
to plan for and secure funding for future construction projects. The OC Flood Manager heads an advisory committee, City Engineers Flood Control Advisory
Committee (CEFCAC) composed of flood control engineers representing cities within
each of the five supervisoral districts, who meet annually to identify and prioritize
construction projects to be included in the multi-year Flood Control Project Plan.
