To guard against sewer damage during floods, we will be relocating vulnerable infrastructure outside of creek areas.
New sewer pipeline will be installed outside of the creek areas in the Lake Forest I and Lake Forest II communities using trenchless boring techniques and traditional open cut trenching.
Watershed improvements will include the installation of 12 riprap check dams. Access routes will also be improved.
Construction expected July 2025 to fall 2026.

Grading will continue in the upper creek area, followed by the demolition of a concrete spillway and hauling away of materials. Retaining walls will be constructed to protect slopes near primary trail, and a new spillway and concrete roads will be created.
Work in the Glenwood area will include a temporary bypass to maintain sewer service during the transition from old pipeline to new, backfilling of trenches where new sewer laterals were installed, and construction of check dams as indicated in the map above.
Improvements to the watershed will also be made, including the installation of 12 riprap check dams.
Some access routes will be improved for easier maintenance of existing and new sewer facilities.
Compacted gravel will be used on paths along the creeks to maintain the natural aesthetics of the area.
Tree removal will be minimized as part of the project design.
