Council reviews stormwater design manual updates to align with Beaufort County and strengthen enforcement
Summary
Town staff presented proposed amendments to the stormwater design manual—clarifying bioretention and pond requirements, adding a 10% analysis flexibility, aligning with Beaufort County, and proposing enforcement mechanisms for pre‑MS4 private communities—before sending the draft to WAPAC and planning commission for public input.
Town staff asked council for direction on a set of amendments to the stormwater design manual intended to clarify technical requirements, tighten enforcement, and align local practice with Beaufort County standards.
Kevin Eichard (town staff) told council the manual is an appendix to the Unified Development Ordinance and that changes would come forward as a resolution. Eichard said the updates include a "10% analysis" flexibility that functions like a variance to give engineers some practical leeway while maintaining watershed protection, adjustments to how pond volumes and bioretention (rain gardens) are calculated, and changes to the manual to be consistent with Beaufort County collections.
Council members asked whether the town gains new enforcement authority for private, pre‑MS4 communities and whether the manual’s water-quality measures consider 25‑year versus 100‑year storm design. Eichard said enforcement provisions are being clarified and that the manual has been in use three years; he recommended sending the draft to the Watershed Action Plan Advisory Committee (WAPAC) on Oct. 24 and to the planning commission for additional input before returning to council. Staff and council discussed retrofit challenges for private community ponds, potential pilot programs (pump maintenance), and how credits for conservation/open space could reduce required pond size.
Why it matters: The manual guides how developments control stormwater to protect waterways. The proposed changes aim to make requirements practicable for site conditions, create clearer enforcement pathways for private communities, and improve consistency with county standards. Council requested follow-up answers on enforcement authority and technical storm-frequency assumptions.
What happens next: Staff will refine the draft, gather technical answers to council questions, and present the amendments to WAPAC and the planning commission prior to returning to council for formal consideration.
