Water quality volume method
Volume Control (Section 2.2.a): stormwater facilities shall capture at least the first two (2) inches of runoff; volume control tied to managing runoff from the 95th percentile storm (§1303.03). Includes water quality treatment, volume control offsets/incentives. Rate Control (Section 2.2.b) uses NOAA Atlas 14 climate-change design rain events.
