Greensboro, NC Environmental Rules: Stormwater Management (2026)

6(B), any development requiring engineered stormwater management must submit a stormwater management plan and a separate maintenance plan to the Planning Director, containing all information required by the Stormwater Management Manual and the Storm Drainage Design Manual; the plan may be combined with any required watershed development plan. The Technical Review Committee approves the plan, timed to be concurrent with or prior to site plan approval, or prior to preliminary subdivision plat approval. 1(F)(1), until the stormwater management plan is approved. 6(B)(4) requires a North Carolina licensed professional engineer to sign, seal, and date a certification that the plan meets the city's stormwater management requirements, both for quality control and, separately, for quantity control before the Water Resources Director grants final approval.

12(C)(1), requires developments using the high-density option to control and treat runoff from the first one inch of rainfall, remove a minimum of 85% of Total Suspended Solids on an average annual basis, discharge the stored volume at a rate no greater than the predevelopment rate for the one-year, 24-hour storm, and hold a runoff drawdown time of at least 48 hours but not more than 120 hours. 6: any development, use, or construction undertaken without required stormwater permits, or inconsistent with an approved plan, is a violation, and each day a violation continues is a separate offense.
