Overview

Led by Orange County Public Works (OCPW), the San Juan Creek Levee Improvements is a vital  project to enhance flood protection and safety for neighboring communities in San Juan Capistrano and Dana Point.
Levee improvements will be made along a 1-mile segment of the San Juan Creek flood control channel. This stretch extends from between Stonehill Drive to the south and approximately Mariner Drive (west side of channel) in Dana Point and Alipaz Street (east side of channel) in San Juan Capistrano.

Project Schedule

Beginning in October 2017, construction will occur Monday through Friday from 7 a.m. to 6 p.m. on both sides of the channel, with occasional Saturday work. No work will occur on Sundays or holidays.
Significant efforts are being made to reduce area impacts and minimize disruptions during work periods. This includes specialized equipment with noise- and  vibration-reduction capabilities, regular watering to limit dust, and more.

Channel Improvements: Sheet Piles

Improvements are necessary to enhance an aging levee that helps safeguard residents, businesses and property from flood waters. The project involves installing steel sheet piles, columns and tension cables,  concrete block walls and support structures, new drainage systems and more. These elements will combine to stabilize and reinforce the levee for years to come. The total project cost is $33 million and is funded by the OC Flood Control District and a $5 million grant from the California Department of Water Resources.

Channel Improvements: Sheet Piles

Sheet piles are long structural sections with a vertical interlocking system that creates a continuous wall. Interlocked sheet piles form a wall that is water resistant and are commonly used for the construction of retaining walls and seawalls.
