East Garden Grove-Wintersburg Channel Project

( Warner Avenue to Goldenwest Street, Huntington Beach )

Join our OC Survey team as they take video with their drone flying over the project on March 2, 2021.


The Project channel reach is currently an earthen trapezoidal leveed section originally designed to convey 65% of the 25-year storm. The Project consists of a series of design elements necessary for the channel reach to meet current design criteria to convey a 100-year storm event, as well as meet federal requirements for national flood insurance.

The project design includes, but is not limited to, the following elements:

  1. Dual-row steel sheet piles installed via the press-in method on each side of the channel

  2. Deep soil-cement mix columns and a maintenance road constructed between the channel side sheet piles and land side sheet piles

  3. Channel widening by removing the resultant trapezoidal channel soil wedge, and;

  4. Water quality Best Management Practices (BMPs).
