Lake Forest Woods Sewer Improvement Project
To guard against sewer damage during floods, Irvine Ranch Water District will be relocating vulnerable infrastructure outside of creek areas in the Lake Forest I and Lake Forest II communities using trenchless and open cut trenching.
Watershed improvements will be made within the creek, including the installation of 12 riprap check dams.
Access routes will also be improved to allow for easier maintenance of existing and new sewer facilities. Some will be paved and others, particularly along the creeks, will be improved with compacted gravel to maintain the natural aesthetics of the area.
Tree removal will be minimized as a part of the project design.

July 2025
Construction work will begin July 7. That work will include setting up equipment and pedestrial traffic control for safety. Tree and brush removal will take place early in the month, and trees will be removed only when necessary for the installation of sewer pipeline or access routes, depending on root conditions encountered during construction work. Crews will begin construction of rip-rap dams toward the end of the month and that work will continue into late August. Other work scheduled this week includes verification of existing sewer connection points and rough grading for access pits in preparation for pipeline installation in August.
