g. All seeded areas shall be mulched immediately with clean straw at <br /> a rate of one and one half (1 %2 ) tons per acre. Mulch shall be <br /> anchored with a disk or tackifier. <br /> h. Buffer areas (both natural and created), shall be protected by silt <br /> fence 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 area widths will be based on the Wetland Protection Strategies <br /> established in the Orono Surface Water Management Plan (SWMP) (December 2002). A <br /> Protection Classification has been assigned to each wetland in Orono based on the <br /> stormwater susceptibility and functional assessment for each wetland. The four <br /> Protection Classifications are described as follows: <br /> Protection Susceptibility Description <br /> Classification Ratin <br /> Highly Highly susceptible to both quantity and quality impacts <br /> "Preserve" Susce tible from runoff;have the hi est de ee of rotection <br /> Moderately Moderatley susceptible to quantity and quality impacts; <br /> "Manage 1" Susceptible protection is less stringent than Preserve,provides <br /> rotection to maintain their characteristics <br /> "Manage 2" Slightly Less stringent protection than Manage 1 wetlands; <br /> Susce tible maintenance of characteristics is desirable <br /> Least Wetlands are significantly degraded(e.g.,cultivated or <br /> "Manage 3" Susceptible canary grass monotype)or lack of wetland characteristics; <br /> not typically impacted by runoff; no quantity and only <br /> limited uali treatment of runoff is re uired <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 copy of <br /> which shall be kept on file in the office of the City Clerk and shall be available for public <br /> review during all normal office hours. The following are the required buffer area widths <br /> for each Protection Classification: <br /> Width of Buffer Additional Protection Requirements <br /> Protection Area from (B=Bounce=change in water level due to runoff event) <br /> Classification Wetland (P=Phosphorus) <br /> Bound <br /> "Preserve" 50 feet B:Maintain bounce at or below existing conditions <br /> P:Limit loadin s to redevelo ment loadin (0.14 Lbs./Ac/Yr) <br /> "Manage 1" 35 feet B:Maintain bounce at or below existing conditions plus 0.5 foot <br /> P:Limit loadings to predevelopment loadings times 2 <br /> (0.28 Lbs/Ac/Yr) <br /> "Manage 2" 25 feet B: Maintain bounce at or belowexisting conditions plus 1.0 foot <br /> P:Limit concentration to predevelopment concentrations(200 <br /> b) <br /> "Manage 3" 16.5 feet B:No quantity requirement <br /> P: Limit concentration to 225 b <br /> Page 7 of 22 <br />
