<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 loadin�o 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 loadings to 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 condition�lus 1.0 foot
<br /> characteristics is desirable P: Limit concentration to
<br /> predevelopment concentrations(200
<br /> �
<br /> "Manage 3" Least Wetlands are significantly degraded B:No quanti requirement
<br /> Susceptible (e.g., cultivated or canary grass P: Limit concentrat_ion to 225 ppb
<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 a11 normal office hours. The Minnehaha Creek
<br /> Watershed District required buffer area widths are based on the four protection
