Planning committee debates draft stormwater and disturbed‑acre thresholds; members ask for more local analysis
Summary
Staff presented draft Land Development Manual text proposing new thresholds for allowable disturbed acreage (phased allowances up to 50–75 acres), additional BMPs and enforcement measures including stop‑work orders; committee members raised concerns about soils, Lake Murray watershed impacts and enforcement staffing and asked staff to return with refined proposals and stakeholder input.
Lexington County planning staff presented a draft revision to the Land Development Manual that would change how much acreage a developer may disturb without additional approvals and would add new stormwater management expectations.
Highlights of the draft included raising staff‑level disturbance thresholds (for example, allowing phased disturbance up to 40–50 acres under an expanded master plan or disturbance stabilization agreement with engineering justification), requiring 80% stabilization before moving to the next phase in some cases, permitting cash surety in lieu of letters of credit for some disturbance stabilization agreements, and requiring additional BMPs (including mulch filter berms, silt fence and turbidity curtains where feasible). Staff emphasized the text was draft and intended to gather stakeholder and committee feedback.
Committee members expressed concern about the proposed thresholds in lake‑adjacent areas, the complexity of measuring stabilization during heavy rain events, the potential for widespread clearcutting and downstream flooding, and the county’s current staffing to enforce stop‑work orders and follow‑up inspections. Several members asked that the document be reviewed with soil/topography sensitivity and that the stormwater advisory board and the Lexington County Soil and Water Conservation District be involved. One committee member said any allowance above 50 acres should involve additional review and possibly council consideration; staff clarified that the staff cap was proposed at 50 acres with higher thresholds requiring SWAB/PC/council review in draft text.
No votes were taken on the draft text; staff said they will continue stakeholder consultation and return with a working document incorporating feedback.
Why it matters: Disturbance thresholds and BMP requirements determine how large construction sites are permitted and regulated; changes could have environmental and infrastructure consequences, particularly in lake and watershed areas.
Next steps: Staff will refine the draft, solicit feedback from SWAB and other stakeholders, and return to committee for additional review.
