This classification requires a 50 foot vegetated buffer and 20 foot setback from the buffer. The proposed house location is outside the required buffer and setback location and meets the requirements of the ordinance. The wetland has an irregular edge in what would be the backyard of the property. The edge of buffer ranges from 30 feet to 65 feet in distance from the house. Buffer Condition and Requirements A site evaluation was completed on July 16, 2008 to determine the condition of the vegetation in the existing upland buffer. Currently a substantial portion of the baffer is turf grass and the remainder of the buffer has been left in a natural grass/forb condition. The natural grass/forb portion of the buffer is currently in adequate shape, however some spot spraying of thistle is recommended. According to Division 3 sec.78-1605 turf grass is considered to be an undesirable plant species and should be removed from the buffer area. After the turf is removed the area is required to be planted or seeded with native species. The applicant will need to provide a ManagemenULandscaping plan that includes the following: 1. Method of establishing native vegetation in turf areas(MN BWSR Web Site— Publication: "Restoring&Managing Native Wetland and Upland Vegetation"source for options). 2. Species proposed to be seeded or planted.According to the ordinance Div.3 Sec.78- 1605(3)the seed mix must contain at least 12 pounds(PLS)per acre of native prairie grass seed and 5 pounds(PLS) per acre of native wildflower seed. The grass mixture must contain a minimum of four species while the wildflower mixture must contain a minimum of five species. (MN BWSR Web Site—Publication: "Restoring&Managing Native Wetland and Upland Vegetation"source for options). 3. Schedule of activities that are part of the maintenance and establishment of native vegetation in the buffer should be provided. Certificate of Survey Requirements Currently the survey shows the total setback line from the wetland, but does not depict the edge of the buffer. The applicant should have the survey company add the edge of the buffer to the survey.
