Dorchester County public works outlines "48-hour" rule for ditching, asks residents to check tide and recent rainfall

Dorchester County public works staff briefed the council on recent storm-related ditching and flooding, describing operational limits and how residents should assess problems before calling county crews.

Director Osborn told the council the county has received 8–10 inches of rain in parts of the county since late June and is responding to frequent short-duration storms that dump one to two inches of rain in an hour or two. Osborn said county crews are focusing on emergency repairs—replacing culverts and cross pipes and conducting ditch work—but that tidal influence and the distance water must travel to an outfall can delay clearing.

"We kinda run off the 48 hour rule right now, and if the ditch is clear within 48 hours, we don't see an emergency or a top priority," Director Osborn said, explaining the office monitors whether water remains above a cross pipe after that interval. He said some drainage areas require water to travel 2.5 miles to reach an outfall and that higher tides can block drainage.

Council members were asked to inform residents that staff investigate each call but that resources are limited, and the 48-hour observation helps the county prioritize response. A council member thanked public works staff for maintenance on Vincent Road as an example of ongoing efforts.

The briefing included operational detail (how far water must travel to outfalls, tidal effects and acreage drained by some systems) but did not result in a formal vote or new policy; staff advised residents to review recent rainfall and tide conditions before contacting the county for a potential ditching emergency.
