r <br />wetland. The city has also established additional protection requirements for each classification. The <br />four protection classifications are described as follows: <br />I <br />Protection Susceptibility <br />Additional Protection <br />Requirements <br />Classification Rating <br />Description <br />(B =Bounce= Change in <br />water level due to runoff <br />event) <br />"Preserve" <br />Highly <br />Susceptible <br />1 Highly susceptible to both quantity and quality <br />impacts from runoff; have the highest degree <br />of protection <br />(P = Phosphorus) <br />B: Maintain bounce at or <br />below existing <br />conditions <br />P: Limit loadings to <br />predevelopment loading 1 <br />(0.14 Lbs/Ac/Yr) <br />I <br />l B: Maintain bounce at or <br />1 <br />"Manage 1 " <br />"Manage 2" <br />I <br />Moderately <br />Susceptible <br />Slightly <br />Susceptible <br />Moderately susceptible to quantity and <br />quality impacts; protection is less stringent <br />than Preserve, provides protection to <br />maintain their characteristics <br />Less stringent protection than Manage 1 <br />wetlands; maintenance of characteristics is <br />desirable <br />-, Wetlands are significantly degraded (e.g., <br />"Manage 3" <br />Least <br />Susceptible <br />_ _J_ <br />cu ltivated or canary grass monotype) or lack <br />of wetland characteristics; not typically <br />impacted by runoff; no quantity and only <br />1 limited quality treatment of runoff is required <br />_I <br />below existing I <br />conditions plus 0.5 foot <br />P: Limit loadings to <br />predevelopment <br />loadings times 2 (0.28 <br />Lbs/Ac/Yr) <br />B: Maintain bounce at or <br />below existing <br />conditions plus 1.0 foot <br />P: Limit concentration to <br />predevelopment <br />concentrations (200 <br />ppb) <br />B: No quantity <br />requirement <br />P: Limit concentration to <br />225 ppb <br />_J <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 widths are based on the four protection clas sifications. <br />Page 8
