<br />RULE C <br />STORM-WATER MANAGEMENT PLANS <br /> <br />1. POLICY. It is the policy of the Board of Managers to: <br /> <br />(a) Manage stormwater and snowmelt runoff on a regional <br />or subwatershed basis and promote natural infiltration <br />of runoff throughout the District to: <br /> <br />(1) Provide effective water quality treatment <br />and where possible provide such treatment prior <br />to discharge to surface waterbodies and <br />wetlands. <br /> <br />(2) Ensure that future peak rates of runoff <br />are less than or equal to existing rates. <br /> <br />(3) Maximize infiltration and control run-off <br />volume increase. <br /> <br />(b) Require stormwater facilities to be constructed on <br />individual sites where regional facilities are not <br />available. <br /> <br />2. REGULATION. A permit and stormwater management plan is <br />required under this rule for new development, redevelopment, or <br />additions to an existing site. <br /> <br />3. DESIGN CRITERIA FOR STORMWATER MANAGEMENT PLANS. Stormwater <br />management plans must comply with the following criteria: <br /> <br />(a) A hydrograph method based on sound hydrologic theory <br />must be used to analyze stormwater runoff for the design <br />or analysis of flows and water levels within and off the <br />project site. <br /> <br />(b) Stormwater runoff rates for the proposed project <br />must not exceed pre-project runoff rates for the critical <br />one-year or two-year and lOO-year frequency events. <br /> <br />(c) Regional detention basins will be utilized to manage <br />peak flow rates and meet water quality objectives where <br />possible. On-site detention basins will be utilized when <br />regional basins are not in place or are not feasible. <br /> <br />(d) Analysis of flood levels, storage volumes, and flow <br />rates for waterbodies and detention basins must be based <br />on the range of rainfall and snow melt durations which <br />produces the critical (highest) flood levels and <br />discharges. <br /> <br />(e) Detention basins must be designed to provide: <br /> <br />11 <br /> <br />. . <br /> <br />I <br /> <br />~ <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />II <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />.. <br />I <br />
