Water quality volume method
Water Quality Capture Volume (WQCV) based on runoff from 0.6 inches of precipitation within the MHFD/UDFCD boundary (≈80th percentile storm); remaining runoff after volume reduction treated through capture and slow release of the WQCV. City drainage portals often HTML/403 — Front Range MS4s commonly apply USDCM Volume 3.
