� ._ f. No fertilizer shali be used in establishing new buffer zones, except on highiy disturbed sites when deemed necessary to establish acceptable buffer vegetation and then limited to amounts indicated by an accredited soil testing laboratory. g. All seeded areas shall be mulched immediately with clean straw at a rate of one and one-half tons per acre. Mulch shall be anchored with a disk or tackifier. h. Buffer areas (both natural and created), shall be protected by silt fence during construction and the fence shali remain in place until the area crop is established, and at that time the fence shall be removed. (c) Buffer area widths will be based on the wetland protection strategies estabiished in the Orono Surface Water Management Plan (SWMP) (December 2002). A protection classification has been assigned to each wetland in Orono based on the stormwater susceptibility and functional assessment for each wetland. The four protection classifications are described as follows: Protection Susceptibility Rating Description Ciassification "Preserve" Highly Susceptible Highiy susceptible to both quantity and quality impacts from runoff; have the highest degree of rotection "Manage 1" Moderately Moderately susceptible to quantity and quality Susceptible impacts; protection is less stringent than Preserve, provides protection to maintain their characteristics "Manage 2" Siightly Susceptible Less stringent protection than Manage 1 wetlands; maintenance of characteristics is desirable "Manage 3" Least Susceptible Wetlands are significantly degraded (e.g., cultivated or canary grass monotype) or lack of wetland characteristics; not typically impacted by runoff; no quantity and only limited quality treatment of runoff is re uired The protection classification for each wetland will be found on the "Wetland Management Classification Map & List" which is hereby adopted by reference, a copy of which shall be kept on file in the office of the city clerk and shall be available for public review during all normal office hours. The following are the required buffer area widths for each protection classification: Protection Width of Buffer Area Additional Protection Requirements (B = Bounce Classification from Wetiand = Change in water level due to runoff event) (P = Boundar Phos horus "Preserve" 50 feet B: Maintain bounce at or below existing conditions P: Limit loadings to predevelopment loadin 0.14 Lbs./Ac/Yr "Manage 1" 35 feet B: Maintain bounce at or below existing conditions plus 0.5 foot P: Limit loadings to predevelopment loadings times 2 (0.28 Lbs/Ac/Yr "Manage 2" 25 feet B: Maintain bounce at or below existing conditions plus 1.0 foot P: Limit concentration to redevelo ment concentrations 200 pb "Manage 3" 16.5 feet B: No quantity requirement P: Limit concentration to 225 b
