Dorchester planning committee backs ordinance to update impervious-surface rules
Summary
Dorchester County planning committee and council committee recommended approval of Ordinance 25-03, a text amendment that raises impervious-surface allowances in certain residential districts and clarifies related language; recommendation was unanimous.
Dorchester County planning and development officials recommended approval Feb. 18 of Ordinance 25-03, a text amendment to the county zoning and land development standards that updates how the county measures and permits impervious surface on residential lots.
The change, presented by planning staff member Libby Reinerson, would increase allowed impervious-surface percentages in some districts — specifically R-3, R-4 and the Mixed-Use Corridor (MUC) — for townhomes and cluster subdivisions and would add clarifying language across other districts to improve readability. Reinerson also told the committee the ordinance updates references from the South Carolina Department of Health and Environmental Control (SCDHEC) to the Department of Environmental Systems (SCDS) where applicable.
The amendment is aimed at reflecting development patterns on smaller lots — where driveways, sidewalks and patios consume a larger share of a parcel — while recognizing that some neighborhood forms trade smaller private lots for larger shared open space. Planning Commission staff previously reviewed the amendment and recommended approval; the planning, development and building committee voted unanimously to recommend third reading of Ordinance 25-03. The committee record shows the public hearing was opened and closed with no speakers and the vote carried unanimously.
County staff said the change does not broadly relax impervious limits across all zones but adjusts standards where townhome and cluster subdivision patterns make the prior thresholds impractical. The ordinance text identifies the specific sections of Article 7 to be amended; the committee proceeded with a recommendation that the full council take third reading.
Approval at committee now sends the ordinance forward for the formal third-reading process required under county rules. The committee recorded the recommendation as unanimous; the transcript does not include a roll-call vote by name in the committee record.
