Redding planning commission certifies EIR and approves pump station 1 use permit despite unavoidable construction noise

The City of Redding Planning Commission on a unanimous vote certified the final environmental impact report (EIR) and approved a use permit for the Pump Station 1 replacement project, which will place a new pump station and associated buildings in the FEMA 100-year floodplain of the Sacramento River and at the confluence with Jenny Creek.

Project planner Lily Tuohy told commissioners the draft EIR had been circulated and revised in response to written comments and that the consultant Jacobs finalized the document for the city. "There is one unavoidable impact and that's with regards to noise," Tuohy said, describing construction noise levels and the need for a statement of overriding considerations as part of final certification.

The nut graf: Commissioners certified the EIR and approved the use permit after staff said hydraulic analysis shows the structure will not change floodplain behavior and fish passage is not expected to be substantially affected, but construction — especially pile driving — will create noise impacts that the mitigation monitoring and reporting program (MMRP) will seek to reduce.

The commission heard technical and community questions about noise, access, project timing and funding. Tuohy said the existing pump station, built about 1937 with major renovations including in 1987, is outdated and cannot be feasibly retrofitted: intake pipes sit too high during low flows and limit capacity. The replacement site is about a quarter-mile upstream on the same riverbank. The new facility will include a raised platform with sheet piles, an electrical room, and a small operations building and restroom. Tuohy said the platform will extend about 40 feet into the Sacramento River, which is roughly 425 feet wide at that location.

Tuohy summarized EIR findings: roughly 60 impact topics were evaluated. Of those, 47 impacts are identified as less than significant, four have no impact, and 10 require mitigation and are reduced to less-than-significant with the proposed measures. Construction noise estimates show average equipment noise at 50 feet of about 87 decibels and pile-driving noise at about 94 decibels; the EIR notes construction will exceed local exterior noise standards (night defined as 10 p.m.–7 a.m.). The EIR and the included MMRP (measure 13-1) list specific mitigation steps — 13-1 contains 14 items intended to reduce intrusion (for example, scheduling noisy equipment, using quieter tools where feasible, and outreach to nearby receptors).

On floodplain and environmental protections, Tuohy said the hydraulic analysis demonstrates the project will not affect floodplain conveyance. The project includes channel restoration for Jenny Creek with an approximate channel slope of 2.6 percent, a 10-foot bottom width, and 2:1 side slopes; staff said the realignment is expected to improve upstream spawning and rearing habitat for salmonids and may improve water quality and wildlife habitat.

Kurt Mayer of the Public Works Department responded to implementation questions and funding queries: "We're pursuing several grants for the Canyon Creek portion of the work and then SRF loans and a WIFIA loan for the pump house and then also water utility funds," Mayer said. He said construction is "optimistically" expected to begin in early 2026 but cautioned that timing depends on securing funding. Mayer said construction will last about two years, and that pile driving — the noisiest activity — will be staged in an agency-permitted window likely lasting a couple of months (staff estimated a winter window such as February–April).

Residents raised concerns about noise and proximity. Anne Silvera, who said she lives on Jenny Creek, asked how the new structure relates to the existing station and warned the Sunset Terrace neighborhood could experience "considerable noise" during the multi-year construction period. Tuohy and Mayer both said contractors and the city plan to provide outreach to sensitive receptors such as Shasta High School ahead of particularly loud activities.

Access and public amenities were clarified: the proposed new Overhill Road access will be pedestrian only (not a through road), and staff said the river-side plaza will be fenced with gated access while a nearby viewing bench area will remain available to the public; staff said bollards and fencing will limit vehicle access. The project packet notes design elements such as a fenced operations area and a viewing area outside the secured zone.

Commission action and next steps: commissioners adopted the findings of fact, the statement of overriding considerations for noise, the MMRP, and a resolution certifying the EIR, and approved the use permit subject to the draft conditions of approval. The Planning Commission vote was recorded as unanimous (6–0, Chair Minor absent). The item does not go to City Council; certification of the EIR and the final use permit decision were made at this hearing.

Ending: Staff and the Public Works Department said they will proceed with grant and loan applications, continue outreach to nearby schools and residents about major construction activities, and provide notices before high-noise work. The schedule remains contingent on funding and regulatory permits for in-river work.
