Chico Airport Sewer Pond Repair Project (Capital Project No. 50358)

The Chico Airport Sewer Pond Repair Project, identified as Capital Project No. 50358, is an infrastructure upgrade initiative led by the City of Chico in Butte County, California. The primary objective of the project is to prevent overflow wastewater from discharging into an abandoned holding pond and mixing with stormwater runoff at a former wastewater treatment plant located southeast of the Chico Regional Airport. Key deliverables include the abandonment and replacement of a storm drain line with approximately 345 feet of 12-inch high-density polyethylene pipe, the installation of a real-time wastewater level sensor in the sewer flow control vault, the construction of a new sewer manhole downstream from the sewer siphon, and the creation of an all-weather crushed rock access road for year-round maintenance. The project is governed by the California Environmental Quality Act and has been supported by a Mitigated Negative Declaration. The California Department of Fish and Wildlife has issued Streambed Alteration Agreement EPIMS Notification Number BUT-65579-R2, confirming that the installation of the stormwater outfall, including the flared end section and rock slope protection, will not have a significant environmental effect. Special contract requirements include strict adherence to cultural resource discovery protocols, requiring an immediate work halt and notification to City of Chico Public Works Engineering if human or non-human remains are uncovered. The project is located on Assessor's Parcel Numbers 047-550-001 and 047-550-006.
