A protection classification has been assigned to <br /> each wetland in Urono based on the stormwater susceptibility and functiona( assessment for each wetland. The <br /> four protection classifications are described as follows: <br /> Protection Classitication Susceptibiliri Ratino Description <br /> "Preserve" Highly Susceptible Highly susceptible to both <br /> quantity and quality <br /> impacts from runoff;have <br /> d�e highest degree of <br /> rotection <br /> "Manaee 1" Moderately Susceptible Moderately susceptible to <br /> quantity and quality <br /> impacts:protection is less <br /> stringen[than Preserve, <br /> provides protection to <br /> maintain their <br /> characteristics <br /> "Manage 2" Slightly Susceptible Less stringent protection <br /> than Manaee I wetlands: <br /> maintenance of <br /> characteristics is desirable <br />
