SPL-2020-1202-NLH Draft SEA/EIR Addendum River Road Dike

Published Dec. 4, 2020

This Draft SEA/EIR Addendum has been prepared as a supplement to the Final Supplemental Environmental Impact Statement and EIR for Prado Basin and Vicinity, Including Reach 9 and Stabilization of the Bluff Toe at Norco Bluffs, dated November 2001.  The 2001 SEIS/EIR identified a number of protective dikes and embankments in the Prado basin necessary to provide protection to nearby residential developments, businesses and infrastructure from a proposed expansion of the reservoir.  This expansion is part of a comprehensive flood risk management project (the Santa Ana River Mainstem Project or SARMP) that extends throughout much of the Santa Ana River watershed.  One of the protective features described in the 2001 SEIS/EIR is the River Road Dike, which is the focus of this Draft SEA/EIR Addendum.  Design modifications have been completed.  The Proposed Action is detailed in Section 2.0 of the Draft SEA/EIR Addendum.
