Water quality volume method
Design Capture Volume (DCV): retain onsite pollutants in runoff from the 24-hour, 85th percentile storm event. If full retention is not feasible, biofiltration for remaining volume (treat 1.5× DCV not retained, or flow-thru biofiltration holding ≥0.75× DCV not retained). Chula Vista participates in the San Diego County regional MS4 program; city portal often 403 — San Diego Stormwater Standards used as regional technical reference pending a durable Chula Vista-specific PDF.
