Aberdeen Town plans dry basins alongside Highway 15501 to ease flooding; DOT schedule may delay work
Summary
Staff displayed DOT plans showing two permanent dry basins (estimated 50,000 gallons each) near Highway 15501 to slow runoff in priority stormwater areas; utilities relocation and DOT timing could delay construction until late summer or fall.
Aberdeen Town staff told commissioners on Feb. 23 that a DOT roadway project (identified in meeting materials as the 15501 project) includes plans for two permanent dry basins near Highway 15501 that are intended to reduce the volume and peak flow of stormwater entering problem areas.
Eric, who prepared an overlay of DOT plans on Google Earth, said the two dry basins are proposed on opposite sides of the highway — one in front of a restaurant and another behind a nearby shopping area — and each basin is estimated to hold about 50,000 gallons. Staff said the basins will not solve all drainage problems but should slow flows and reduce peak discharges into the identified priority area at Johnson and Adrian.
Construction timing depends on DOT and on relocating dry utilities in the project area; staff estimated late summer or fall as the earliest likely window. Separately, staff said Duke Energy addressed a retention-pond issue on Lock Cabin Lane that previously sent runoff onto a homeowner’s driveway and reported that the fix has held up since the work.
Next steps: town staff will meet with DOT on the pedestrian/sidewalk project in the coming week to review history and data and seek cooperation on drainage solutions; the board will receive updates as design and utility-relocation timelines firm up.
