Water quality volume method

Priority Projects must meet LID performance criteria by retaining/treating the Design Capture Volume (DCV) for the water quality design storm via infiltration, evapotranspiration, biofiltration, or detention near the source. Hydrologic Conditions of Concern (HCOC) performance criteria address hydromodification. Mojave River Watershed has a separate TGD.

“Design Capture Volume or "DCV" / LID Performance Criteria”
Section 4.1

Peak flow calculation method(s)

Design Capture Volume (DCV) calculation for LID, HCOC / hydromodification performance criteria, LID BMP selection and feasibility evaluation
