Stormwater run-off rates are shown in cubic feet per second (cfs) for pre-settlement site conditions, existing site conditions (pre-project), and designed site conditions, with the goal of having the design run-off rates minimized to at or below pre-settlement levels. For projects using Version 2.1 of the B3 Guidelines (entering the Schematic Design phase in the B3 Tracking Tool before May 1st, 2013) these rates are for the 100-year, 24-hour precipitation event. For projects using Version 2.2 of the B3 Guidelines, these rates are for the 10-year, 24-hour precipitation event.
