Water quality volume method

City Design & Construction Manual adopts APWA Section 5600 Default Strategy: Comprehensive Protection — peak control for 1%, 10%, and 50% chance storms plus volumetric/extended detention of the 90% mean annual event. Water quality via MARC/APWA BMP Manual: WQv captures 90% of average annual runoff using 1.37-inch Water Quality Storm for KC metro (WQv = P × Rv).

“Default Strategy: Comprehensive Protection Peak runoff control shall be provided for the 1%, 10% and 50% chance storms and volumetric and/or extended detention control of the 90% mean annual event ... WQv captures 90% ... 1.37-inch Water Quality Storm”
