The Santa Ana River Project, authorized for construction by the Water Resources Development Act of 1986, is designed to provide urban flow protection to the growing communities in Orange, Riverside and San Bernardino Counties. The formulation of the project plan addressed problems and issues related to hydrologic change to the watershed (from rural to urban), change in the damage center to be protected (agriculture with limited urban development to high density urbanization), and change in the basis of level of protection afforded. Due to the relatively large areal extent and diversity of channel characteristics, a wide variety of flood control measures, both structural and floodplain management were incorporated into the recommended project plan.
