Document Description
The City of Oceanside (City) is proposing to implement several sewer improvement projects to upgrade and supplement existing infrastructure. Several specific projects have been identified thus far, including: • Oceanside Mesa Garrison Force Main (OMG FM) Project • El Corazon Lift Station Project • Land Outfall Replacement Project • Mission Avenue Lift Station Force Main (MALS FM) Replacement Project • Mission Avenue Gravity Sewer Lining and Replacement Project The OMG FM Project involves the design and construction of approximately 15,000 linear feet (LF) of 36-inch sewer force main between the San Luis Rey Water Reclamation Facility (SLRWRF) and the proposed El Corazon Lift Station (discussed below). The OMG FM would carry flows from the existing and future lift stations. The majority of the pipeline would occur outside of paved roadways and within easements. The El Corazon Lift Station Project involves the design and construction of a five-million-gallons-per-day (MGD) sewer lift station near the intersection of Mesa Drive and Garrison Street. The City is considering purchasing the permanently closed Garrison Elementary School property for the lift station. The City would then sub-divide the 11.2-acre property, retaining 1.5 acres for the lift station, as well as a 50-foot-wide public easement along the east property line, for future utilities and maintenance access. The remaining property would be used by other City departments or sold to a prospective developer. The Project would use the 1.5-acre site for the lift station and associated components, including a wet well, emergency storage, future pipelines, parking, training (open area), and equipment storage. The Project would also include rerouting gravity flows in Mesa Drive and Garrison Street to the new sewer lift station, connections to existing or future sewer mains, and extension of nearby sewer mains. The Land Outfall Replacement Project involves upsizing of approximately 29,000 LF of existing 24 inch pipe to 36 inch pipe between the SLRWRF and the La Salina Wastewater Treatment Plant (LSWWTP) in various segments. Approximately 19,000 LF from SLRWRF to the south entry of Garrison Elementary School generally follows the same corridor as the Proposed OMG FM Project. Of the remaining 10,000 LF of pipe to be replaced, approximately 4,000 LF is located near the North County Transit District Railroad right-of-way, and the other 6,000 LF is located in Oceanside Boulevard and Garrison Street. The MALS FM Replacement Project involves the replacement of approximately 13,000 LF of existing 24-inch sewer force main from the SLRWRF to the Mission Avenue Lift Station with a new parallel pipeline or in-place replacement. If a new parallel pipe is constructed, the existing 24-inch MALS FM may be taken offline, cleaned, assessed, and repaired to serve as a backup force main to improve the reliability of the City’s sewer system. The Mission Avenue Sewer Lining and Replacement Project includes cured-in-place lining of approximately 600 LF of 24-inch gravity sewer pipe starting at 3560 Mission Avenue and traveling southwest to Fireside Street. From Fireside Street in Mission Avenue southwest to the Mission Avenue Lift Station, approximately 1,600 LF of the 24-inch pipe would be upsized to a 30-inch and/or 36-inch pipe. The existing upstream segment of the sewer is located in private easements through the Marketplace Del Rio commercial shopping center and undeveloped parcels owned by the Ocean KAMP development. The new replacement pipe would be relocated into Mission Avenue, where feasible. Collectively, the projects included in the PEIR would provide necessary improvements to the existing sewer infrastructure in order to accommodate future increased flows, improve reliability of system to divert LSWWTP flows to SLRWRF, replace outdated pipelines, and avoid effluent spills, as well as provide a backup safety precaution should the Pure Water (Advanced Water Treatment Facility) and/or Recycled Water production facilities need to be taken offline unexpectedly or for maintenance purposes.
