A protection classification has <br /> been assigned to each wetland in Orono based on the stormwater susceptibility <br /> and functional assessment for each wetland. The City has also established <br /> additional protection requirements for each classification. The four protection <br /> classifications are described as follows: <br /> Protection Susceptibility Description Additional Protection Requirements <br /> Classification Rating B=Bounce=Change in water level due <br /> to runoff event) <br /> (P=Phosphorus) <br /> "Preserve" Highly Highly susceptible to both quantity and B: Maintain bounce at or below existin� <br /> Susceptible quality impacts from runoff;have the conditions <br /> highest degree of protection P: Limit loadings�predevelopment <br /> loadin�(0.14 Lbs./Ac/Yr) <br /> "Manage 1" Moderately Moderately susceptible to quantity and B: Maintain bounce at or below existin� <br /> Susceptible quality impacts;protection is less conditions plus 0.5 foot <br /> stringent than Preserve,provides P: Limit loadin�predevelopment <br /> protection to maintain their loadings times 2(0.28 Lbs/Ac/Yr) <br /> characteristics <br /> "Manage 2" Slightly Less stringent protection than Manage B: Maintain bounce at or below existin� <br /> Susceptible 1 wetlands; maintenance of conditions plus 1.0 foot <br /> characteristics is desirable P: Lixnit concentration to <br /> predevelopment concentrations(200 <br /> PP�� <br /> "Manage 3" Least Wetlands are significantly degraded B:No quantitv requirement <br /> Susceptible (e.g., cultivated or canary grass P: Limit concentration to 225 pnb <br /> monotype) or lack of wetland <br /> characteristics; not typically impacted <br /> by runoff; no quantity and only limited <br /> quality treatment of runoff is required <br /> The protection classification for each wetland will be found on the "Wetland <br /> Management Classification Map & List" which is hereby adopted by reference, a <br /> copy of which shall be kept on file in the office of the city clerk and shall be <br /> available for public review during all normal office hours. The Minnehaha Creek <br /> Watershed District required buffer area widths are based on the four protection <br /> classifications. �� �"�«��~�- �~'� t�c.�eq��e��ea����€e�--e�k <br /> Page 5 of 13 <br />
