Atascadero Creek Lake Fill Pipeline Repair Project

The City of Atascadero is undertaking the Atascadero Creek Lake Fill Pipeline Repair Project to address the degradation of approximately 350 linear feet of pipeline that transports water from Atascadero Creek to Atascadero Lake during high-flow events. The project involves replacing the damaged pipeline segment with an equivalent capacity pipe installed in the same alignment, along with repairing associated concrete hold-downs and maintaining existing intake structures and diversion boxes. Approximately 96 cubic yards of excavation will be required to remove the old pipeline and clear riparian vegetation adjacent to and above the pipeline. The work is located in Atascadero, California, with a NAICS code of 237120 for sewer line and related utility construction. The project is posted as a forecast on July 2, 2026, with no solicitation number or estimated contract value provided. Environmental compliance and pollution control are central to the project’s execution. All construction personnel must undergo training conducted by a qualified biologist covering special-status species, protection measures under discretionary permits, and the implications of violating the Federal and California Endangered Species Acts. A sign-in sheet and training fact sheet must be maintained and distributed. Construction activities must adhere to strict erosion and sediment control requirements, including daily maintenance of silt fences and fiber rolls, implemented according to approved design and operational standards. All fueling, equipment maintenance, and staging areas must be located at least 50 feet from any water body, and an on-site spill plan with oil absorbent pads must be available. Fugitive dust must be monitored to ensure emissions remain under 20% opacity, with designated personnel reporting to the APCD Compliance Division, and no idling of diesel equipment is permitted. Upon completion, all disturbed areas must be restored to pre-project contours, and all equipment, materials, and temporary best management practices must be removed from the site. Supporting documentation includes site photographs, species data, and a mitigation summary table to support environmental permitting and compliance.
