Improvements to 23 miles of existing channel from Weir Canyon Road to the Pacific Ocean include channel widening, improvement to the existing Greenville-Banning Channel located parallel to the river near the coast, relocation of Talbert Channel ocean outlet and construction of rock jetties and derrick stone jetties at the mouth of the river, and bridge modifications to accommodate the widened channel. In the Santa Ana Canyon area, construction will be limited to bank armoring to protect a mobile home park, residential tract and the 91-freeway.
The construction in the Santa Ana Canyon Area also include the bank protection on the south side along the SR-91(upstream of SAVI Ranch) and on the north side upstream of Weir Canyon Road. In the future, the stretch of channel from Coal Canyon to the Prado Dam will be improved.
