Document Description
The Irvine Ranch Water District (IRWD) proposes to replace, relocate, and protect portions of their existing sewer facilities that are at risk of damage from erosion by the adjacent San Diego Creek and Glenwood Tributary and provide associated access improvements (proposed Project) within The Woods community in Lake Forest, California. The objective of the proposed Project is to reduce risk to infrastructure caused by scour by relocating the existing sewer facilities in the creek to areas outside the scour zone where feasible or using stream bed improvements such as new grade control structures to reduce the potential for scour and adding concrete encasement to protect new or existing sewer facilities that cannot be relocated outside the scour zone. The proposed project would also include access improvements for ongoing maintenance of the sewer facilities. In total, IRWD would install approximately 850 feet of new sewer pipeline within Upper San Diego Creek and approximately 500 feet of new sewer pipeline in the Glenwood Tributary. In addition, IRWD proposes to install ungrouted riprap check dams and bank stabilization measures at several locations within Upper San Diego Creek and the Glenwood Tributary to reduce scour and protect existing sewer infrastructure and access roads. Riprap check dams would consist of large, ungrouted, rock riprap underlain with unwoven fabric and compacted fill.
