DPW: street flooding tied to debris and intense storms; department outlines seasonal cleaning and response plans
Summary
DPW told the committee street flooding is usually surface flooding caused when debris and litter block catch basins during intense downpours; crews respond with 24-hour on-call teams while the department plans seasonal sweeping and targeted hot-spot work.
Department of Public Works staff briefed the committee on the city’s flood response and stormwater operations, linking repeated surface flooding primarily to debris in curb lines and catch basins and to the intensity of rain events.
Commissioner Gerald Krusiak and Jason Sanders, sewer services manager, said the sewer system is generally operating as designed but that heavy short-duration rainfall and debris accumulation cause surface flooding at low points and major intersections. Sanders described field response during storms: crews staff structures to hold back debris and clear drains so water can pass, and the department maintains on-call crews 24 hours for storm events.
DPW described seasonal preventive steps: structure and catch-basin cleaning begins in April; catch basins are on a three-year cleaning cycle with some low-lying or combined-sewer areas cleaned twice a year. The department has conducted an intensified street-sweeping program in spring and plans targeted pre-storm sweeping at identified hot spots.
Committee members suggested piloting additional proactive sweeping and tighter coordination with parking enforcement to enable curbline sweeping where parked cars currently block sweepers. Officials said prior pilots that required temporary no-parking and towing have community pushback but that targeted experiments are possible; staff said they will explore a pilot in Concordia and other hotspots.
The committee also reviewed related DPW operations including the neighborhood cleanup dumpster program, which has collected more than 51 tons in the first two Saturdays of the current season, and the “No Mow May” registration and vacant-lot mowing schedule. Staff said expanding dumpster availability requires additional weekend crews and funding.
Committee members requested a list of repeat flood locations, a plan for pre-storm sweeping pilots in identified hotspots and follow-up on coordination with contractors and parking enforcement to improve curb access for sweepers and catch-basin cleaning.
