OC Flood Santa Ana River Project description
Local Cooperation Agreement
On December 14, 1989, the U.S. Army Corps of Engineers (COE) and the County Flood
Control District of Orange, Riverside and San Bernardino as Local Sponsors, entered
into a four-party Local Cooperation Agreement (LCA) defining the responsibilities
and cost-sharing of each party for each feature.
The Local Sponsors are to acquire all lands, easements, rights-of-way and perform
relocations required to make way for construction of the Mainstem Project. The COE
will construct the improvements. On completion, the Local Sponsors are responsible
for the operation and maintenance of the Project features; except for Prado Dam
where Orange County is responsible to pay for incremental operations/maintenance
costs and the COE will continue to operate the Dam.
Congress authorized Santa Ana River Mainstem Project for construction in 1986 under
new guidelines for cost sharing of water resources projects between Federal and
local governments. The local sponsors must pay between 25% and 50% of total cost
of the project with the remaining cost provided by the Federal government.
In 2003, a new agreement was entered between the Corps of Engineers and Orange County
Flood Control District where Prado Dam feature of the Santa Ana Mainstem Project
was separated and Orange County was a sole local sponsor for Prado Dam.
