Article IV, section B.1.c.(1):
c. Release Rates And Discharges
(1) Unless otherwise specified in appendix J, an SMC- adopted basin plan or floodplain study, the detention volume required shall be calculated using a rating curve based on maximum release rates of 0.04 cubic feet per second per acre for the 2-year, 24-hour storm event and 0.15 cubic feet per second per acre for the 100-year, 24-hour storm event. The release rate requirement shall apply to the hydrologically disturbed area of the ownership parcel unless the enforcement officer determines that specific locations of the ownership parcel have unique circumstances such that the release rate shall apply to a broader or smaller area. The release rate requirements shall only apply to developments listed in article IV, section A.1.f. and article IV, section A.1.g. The volume of detention required shall be based on storing all the run-off from the site for the 100-year 24-hour storm event with zero release. An SMC approved hydrograph producing run-off calculation method shall be used to determine run-off volume.
Article IV, section B.1.g.(3)(d) and (e):
