<br />Water Qualitv <br /> <br />Rule Objective <br />Remove sediment, pollutants, and nutrients from stormwater to protect surface water quality. <br /> <br />Technical Criteria (CRWD & RWMWD) <br />Developments and redevelopments must incorporate effective non-point source pollution reduction BMPs to <br />achieve 90% solid removal. Credits will be given for the volume of water infiltrated. <br /> <br />Rule Threshold <br />All development and redevelopment I acre or greater, <br /> <br />Flooding <br /> <br />Rule Objective <br />Provide for the long-term function of floodplains to provide stormwater storage while protecting property. <br /> <br />Technical Criteria (CRWD & R"'MWD) <br />A structure's lowest floor elevation must be 2 feet above the 100 year high water level of adjacent ponds and <br />water bodies, <br /> <br />Placement of fill within the 100-yr floodplain is prohibited, unless compensatory storage is provided. <br /> <br />Rule Threshold <br />All developments, redevelopments or grading that disturb greater than 1,000 square feet of land within a <br />district floodplain. <br /> <br />Wetland Management <br /> <br />CRWD Rule Objective <br />CRWD has very few wetlands remaining. The objective of the wetland rule is to provide protection to a <br />greater level than the Wetland Conservation Act for the few remaining wetlands <br /> <br />Technical Criteria <br />Wetlands shall not be drained, filled wholly or in part, excavated, or have sustaining hydrology impacted <br />such that there will be a decrease in the inherent (existing) functions and val ues of the wetland. Wetland <br />impacts will be evaluated based on the following principles in descending order of priority. Avoid the <br />impact to the wetland, minimize the impact to the wetland, replace the wetland that was impacted, Wetland <br />impacts will be governed by a Rule comparable to the Wetland Conservation Act, with the following <br />exceptions: <br />1. The de minimis size will be zero. <br />2. Flexibility Sequencing will not be allowed. <br />3. Public Value Credits can not be used for replacement. <br /> <br />A 25-foot buffer of permanent nonimpacted vegetative ground cover abutting and surrounding a wetland is <br />required. <br /> <br />Rule Threshold <br />This rule will apply to all wetlands in CRWD. <br /> <br />Technical Criteria for Rules - June 29, 2005 <br /> <br />2 <br />
