I <br />wetland. The city has also established additional protection requirements for each classification. The <br />four protection classifications are described as follows: <br />Additional Protection <br />Requirements <br />Protection Susceptibility (B = Bounce = Change in <br />Classificat ion Rating <br />Description water level due to runoff <br />event) <br />(P = Phosphorus) <br />B: Maintain bounce at or <br />Highly susceptible to both quantity and quality <br />below existing <br />"Preserve" <br />Highly impacts from runoff; have the highest degree <br />conditions <br />Susceptible P: Limit loadings to <br />of protection predevelopment loading <br />(0.14 Lbs/ Ac/Yr) <br />I <br />B: Maintain bounce at or <br />I <br />I Moderately susceptible to quantity and <br />below existing <br />conditions plus 0.5 foot <br />Moderately quality impacts; protection is less stringent <br />"Manage 1" P: Limit loadings to <br />Susceptible than Preserve, provides protection to <br />maintain their characteristics <br />predevelopment <br />loadings times 2 (0.28 <br />Lbs/Ac/Yr) <br />B: Maintain bounce at or <br />below existing <br />Slightly <br />Less stringent protection than Manage 1 conditions plus 1.0 foot <br />"Manage 2" I wetlands; maintenance of characteristics is P: Limit concentration to <br />Susceptib le desirable predevelopment <br />concentrations (200 <br />ppb) <br />Wetlands are significantly degraded (e.g., B: No quantity <br />cultivated or canary grass monotype) or lack <br />Least requirement <br />"Manage 3" <br />Susceptible <br />of wetland cha ra cteristics; not typically P: Limit concentration to <br />impacted by runoff; no quantity and only 225 ppb <br />limited quality treatment of runoff is required <br />I <br />The protection classification for each wetland will be found on the "Wetland Management Classification <br />Map & List" which is hereby adopted by reference, a copy of which shall be kept on file in the office of <br />the city clerk and shall be available for public review during all normal office hours. The Minnehaha <br />Creek Watershed District required buffer area width s are based on the four protection classifications. <br />Page 8
