Council places higher priority on neighborhood drainage, enhanced stormwater maintenance
Summary
Council flagged enhanced stormwater maintenance and neighborhood drainage improvements as priorities during CIP ranking; staff outlined block-by-block concrete swale work, roll-top curve diversions and an annual $500K neighborhood-improvement program with an option to scale to $2M for broader maintenance.
Council members pressed staff about neighborhood flooding and whether listed D projects should be advanced. Public-works staff described two programs: (1) a concrete-swale/roll-top curve approach used on Chamberlain Avenue to divert surface water into existing drainage and (2) an enhanced stormwater-maintenance program to open outfalls, clear ditches and remove debris.
"We essentially go in and we divert that drainage by roll top curves, to the existing drainage system," the public-works presenter explained when describing the neighborhood concrete-swale approach. Staff said the block-by-block neighborhood infrastructure improvements cost roughly $250K per block and that $500K per year has been programmed for neighborhood drainage work; an enhanced stormwater maintenance program tied to the stormwater utility was described as a $2M annual option to expand citywide maintenance.
Council prioritized enhanced stormwater maintenance during the dot-ranking; staff said revenue options include modest stormwater-utility fee increases and federal grants (including potential earmarks) for larger shoreline or beach work.
