ARTIGLE XI. WETLANDS PROTECTION Page 5 of 12 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 shall 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 established 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 functionat assessment for each wetland. The four protection classifications are described as follows: TABLE INSET: Protection Susceptibility Ctassification Rating Description Highly Highly susceptible to both quantity and quality impacts from "Preserve" Susceptible runoff; have the highest degree of protection Moderately Moderately susceptible to quantity and quality impacts; "Manage 1" Susceptible protection is less stringent than Preserve, provides protection to maintain their characteristics Slightly Less stringent protection than Manage 1 wetlands; "Manage 2" Susceptible maintenance of characteristics is desirable Least Wetlands are significantly degraded (e.g., cultivated or "Manage 3" Susceptible canary grass monotype) or lack of wetland characteristics; not typically impacted by runoff; no quantity and only limited quality treatment of runoff is required 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 availabfe for public review during all normat office hours. The following are the required buffer area widths for each protection classification: TABLE INSET: Width of Buffer Protection Area Additional Protection Requirements Classification from (B = Bounce = Change in water level due to runoff event) Wetland (P = Phosphorus) Boundary B: Maintain bounce at or below existing conditions "Preserve" 50 feet P: Limit loadings to predevelopment loading (0.14 Lbs./Ac/Yr) B: Maintain bounce at or below existing conditions plus 0.5 "Manage 1" 35 feet foot P: Limit loadings to predevelopment loadings times 2 (0.28 Lbs/Ac/Yr) B: Maintain bounce at or below existing conditions plus 1.0 http://library2.municode.com/default/DocView/13094/1/109/120 1/18/2008
