The Flood Control and Water Conservation District uses Drainage Areas as a primary method of planning and implementing flood control facilities. Funding of a Drainage Area (DA) projects is primarily through development fees.
The Drainage Area Fee Ordinances are enacted by the County Board of Supervisors as the governing body of the Flood Control District. It requires payment of the DA Fees (PDF) before the filing of the Final Map.
Fees are paid to the FCD directly, or via cities per Fee Collection Agreements. Fees are based on the cost of the proposed Drainage Area improvements and the expected new impervious surface created by the General Plan build-out.
