Project Description
The Orange County Beach Erosion Control Project from San Gabriel River to Newport Bay (commonly referred to as Surfside Sunset is a mitigation project, designed as remediation for beach erosion damage largely incident to Federal flood control, navigation, and defense projects, with the mitigation meant to last as long as necessary and requires justification prior to each new cycle/Stage. The project restores the 17 miles of coastline from the mouth of the San Gabriel Ricer down coast to Newport Bay Harbor entrance. The project provides periodic beach nourishment of approximately 1.8 million cubic yards of sand every five years. The project is authorized by Rivers and Harbors Act of 1962, Section 101, P.L. 87-874, 23OCT62 (76 Stat, 1177). Re-informed by WRDA 2000. Section 551 dated 11DEC00.
Stage 13 Periodic Nourishment
Stage 13 will place 1.75 million cubic yards of sand, mainly on the Surfside Beach area. The proposed beach will be about 4,500 feet in length, and between 350 and 900 feet in width. About 100,000 cubic yards will be backpassed from Newport beach. The borrow site will adjacent to the Santa Ana River.
The project is currently in the Preconstruction, engineering and design p hase that includes preparation of design documents, environmental compliance, real estate activities through to construction contract advertisement. Plans include an environmental window to avoid grunion, meaning that construction will likely take place between March 15th and September 1st.
Environmental Assessment (EA) was completed for approximately 1.2MCY with FONSI signed 8FEB19. A Supplemental Environmental Assessment (SEA) is in progress to address the fully authorized volume of 1.75MCY.
