Feasibility Study
A feasibility study is a crucial first step in evaluating potential projects for RivCoParks. It assesses the practicality and sustainability of proposed initiatives by analyzing key factors such as environmental impact, financial viability, technical requirements, and community benefits. By conducting a detailed review of each project's scope, cost, and alignment with organizational goals, feasibility studies help ensure informed decision-making and responsible use of resources. This process also identifies potential challenges early, allowing for adjustments that improve the likelihood of successful project implementation while maintaining the highest standards of environmental stewardship and public service.

Santa Ana River Basin - Riverside Levees Rehabilitation Project
Project Description: This U.S. Army Corps of Engineers (USACE) led Santa Ana River Basin- Riverside Levees Rehabilitation Project will rehabilitate damaged portions of the Federally constructed Riverside Levee 1 (West levee) and Riverside Levee 2 (East levee), collectively the "Riverside Levees," which are part of the Santa Ana River levee system. Approximately 9,000 feet of the West levee will be rehabilitated starting from Market Street and continue southwesterly downstream to just past Capary Road. Approximately 4,000 feet of the East levee will be rehabilitated starting from the County line and continue southwesterly downstream to approximately Columbia Avenue. This project also includes a short reach of the East levee between Market Street and State Route 60. Levee rehabilitation will include replacing and grouting the existing levee rock slope protection, as well as extending the rock slope protection.
Two temporary detours are now open to allow continued access through the area:
• Detour 1: Riverside Avenue/Main Street to Columbia Avenue (exhibit below)
• Detour 2: Market Street Bridge to CA Highway 60 (exhibit below)
Both detours are marked with signage and are expected to remain in place until approximately July 2026. Detours will be removed, and the Santa Ana River trail, will reopen as soon as work in each area is complete.
