City staff outlines $3–4 million sewer phase and stormdrain upgrades; Moraga Avenue pedestrian improvements funded by Alameda County grant
Summary
Daniel told the commission the city plans significant sewer work this fiscal year — a Phase 6 sewer replacement estimated at about $3–4 million and concurrent Phase 7 design — and described a strategy of oversizing inlets and adding detention to handle more intense storms instead of costly full-pipeline replacements.
City engineering staff gave a broad overview of capital projects affecting parks and the municipality, including a large sewer-replacement phase and storm-drain and pedestrian-safety work. Daniel said the city expects to put a Phase 6 sewer-replacement contract out to bid this fiscal year and that Phase 6 is "about a 3 to $4,000,000 project for sewer," while Phase 7 is in design concurrently.
To address more intense, concentrated storms, staff described a strategy of oversizing catch basins and designing on-site detention so peak flows can be held temporarily and released slowly through existing pipes rather than immediately replacing long reaches of undersized pipeline — a less costly alternative to tens-of-millions-in-pipeline replacement. Daniel also highlighted a Moraga Avenue pedestrian-safety project largely funded by an Alameda County grant.
