Document Description
Eastern Municipal Water District (District) is proposing the Calle Medusa Sewer and Access Road Emergency Repair Project (project) for the emergency repair of an existing sewer maintenance access road and protection of an existing 10-inch gravity sewer. The sewer was installed in 1991 and serves approximately 700 homes in the Solana Vista, Tierra Vista, and Saddlewood Homeowner’s Associations (HOAs). The sewer alignment originates at Calle Medusa within the HOAs and crosses undeveloped land adjacent to an unnamed creek before discharging into a sewer within Nicholas Road, all within the city of Temecula. The multiple storms of 2023 have caused aggressive erosion and migration of the creek; impacting the sewer access road and preventing maintenance access to the sewer at one location, imposing an imminent threat of exposure and potential damage to the existing sewer routed along the access road. Based on the potential loss of critical services to the community, under emergency conditions, District staff has been working with pertinent regulatory agencies to inform them of the emergency actions. Agencies that were contacted include the U.S. Army Corps of Engineers Regional Water Quality Control Board and California Department of Fish and Wildlife. The emergency declaration has streamlined upfront environmental assessment work and has allowed for corrective action to be implemented in a timely manner. The project addresses emergency repair to the existing slope protection and access road, including soils testing for verification of cement mix design, onsite observation, and testing of onsite soil cement mixing, hydroseeding, revegetating, and environmental monitoring as required by regulatory agencies.
