Buffer areas (both natural and created}, shall be protected by silt <br /> fenca during construction and the fence shall remain in place until <br /> the area crop is established, and at that time the fence shall be <br /> removed. <br /> (c) Buffer ai�ea widtlis will be based on the Wetland Protection Strategies <br /> established in the Orono Surface �ater Management Plan (SWMP) (December 2002). A <br /> Protection C19ssification has been assigned to each wetland in �rono based on the <br /> stormwater susceptibility and fiuictional assessment for each wetland. The four <br /> Protection Classifications are described as follows: <br /> Protection Susceptibility Description <br /> Classification Rati � <br /> Hi ly Highly sasceptibEe to both qua�itity and quality impacts <br /> "Preserve" Susce tible frotn runoff;have the hi hest de ree of rotection <br /> Moderately Moderatley susc ptible to quantity and quality impacts; <br /> "1�Ianage i" Susceptible protection is less stringent than Preserve,provides <br /> rotection to maintain their characteristics <br /> "Manage 2" SlightIy Less stringent protection than Manage 1 wetlands; <br /> Sus tibie maintenance of characteristics is desirable <br /> � L.east We:lands are sigr►ificantly degraded(e.g.,cultivated or <br /> "Manage 3" Susceptible canary grass monotype)or lac[c of wetland characteristics; <br /> not typically impacted by runoff;no quantity and only <br /> limited uaIi treatment of ru�zoff is re uired <br /> The Protection Classification for each wetland will be found on the"Wetland <br /> Management Classif catian Map 8c List" which is hereby adopted by reference, a copy of <br /> which shall be kept on fiie in the office of the City Clerk and shall be available for public <br /> review during all normal office hours.
