• <br /> landscape plan must be submitted to the planning director, which restoration shall include, replanting and maintaining <br /> •according to each of the following guidelines: <br /> a. Buffer areas shall be planted with a seed mix containing 100 percent perennial native plant species, <br /> except for a one-time planting of an annual nurse or cover crop such as oats or rye. <br /> b. The seed mix to be used shall consist of at least 12 pounds pure live seed (PLS) per acre of native prairie <br /> grass seed and five pounds PLS per acre of native forbs. Native prairie grass and native forb mixes shall contain no fewer <br /> than four and five species respectively. <br /> c. The annual nurse or cover crop shall be applied at a rate of 20 pounds per acre. <br /> d. Native shrubs and or trees may be used in addition to forbs and grasses. Shrubs shall be distributed so as <br /> to provide a natural appearance and shall not be planted in rows. <br /> e. Native prairie grasses and forbs shall be planted by a qualified contractor. <br /> f. No fertilizer shall be used in establishing new buffer zones, except on highly disturbed sites when deemed <br /> necessary to establish acceptable buffer vegetation and then limited to amounts indicated by an accredited soil testing <br /> laboratory. <br /> g. All seeded areas shall be mulched immediately with clean straw at a rate of one and one-half tons per <br /> acre. Mulch shall be anchored with a disk or tackifier. <br /> h. Buffer areas (both natural and created), shall be protected by silt fence during construction and the fence <br /> shall remain in place until the area crop is established, and at that time the fence shall be removed. <br /> (c) Buffer area widths will be based on the wetland protection strategies established in the Orono Surface <br /> Water Management Plan (SWMP) (December 2002). A protection classification has been assigned to each wetland in <br /> Orono based on the stormwater susceptibility and functional assessment for each wetland.The four protection <br /> classifications are described as follows: <br /> Protection Susceptibility Rating Description <br /> Classification <br /> "Preserve" Highly Susceptible Highly susceptible to <br /> both quantity and <br /> quality impacts from <br /> runoff; have the <br /> highest degree of <br /> protection <br /> "Manage 1" Moderately Moderately <br /> Susceptible susceptible to quantity <br /> and quality impacts; <br /> protection is less <br /> stringent than <br /> Preserve, provides <br /> protection to maintain <br /> their characteristics <br /> "Manage 2" Slightly Susceptible Less stringent <br /> protection than <br /> Manage 1 wetlands; <br /> maintenance of <br /> characteristics is <br /> desirable <br /> 5 <br />
