Commission backs code changes tightening retaining‑wall standards, inspection and submittal requirements
City engineering proposed a near‑complete rewrite of municipal code 17.61.30 to close safety gaps: gravity (decorative) walls under 4 feet remain exempt if no surcharge; any wall over 4 feet or with surcharge must be engineered and permitted; staff also proposed raising nonresidential maximum engineered wall height to 10 feet and adding clearer inspection and submittal standards. The commission voted 5–0 to recommend the changes to council.
