<br />Page 5 of 19 <br />The Master Plan focuses primarily on the retention and enhancement of buffer areas <br />along the westerly and southerly borders of the non-developing sanitary landfill <br />portion of the site, depicted as Areas A, B and C. Where buckthorn exists, it will <br />be required to be removed. Specific seed mixes are proposed for the buffer areas. <br />Stormwater will be managed by a storm sewer system directing runoff to a filtration <br />basin and ponding area at the west end of the development site, discharging to the <br />existing wetlands. Rate, volume and sediment control are addressed. <br />Direct wetland impacts will be avoided. Wetland buffers are proposed including <br />buffer averaging intended to meet MCWD requirements. Wetland and hydrologic <br />connections will be maintained. <br /> <br />13. Wetlands on Site and/or Impacted. The property contains 2 distinct areas that <br />have been delineated as Preserve wetland. No wetlands are proposed to be <br />impacted. Buffer averaging is proposed subject to MCWD rules and requiring that <br />agency’s approval. The reported MCWD base buffer width requirement is <br />reported as 75 feet, with a minimum of 67 feet. Applicants have proposed a buffer <br />avregae of 71 feet, ranging in actual buffer width of 40 feet adjacent to the north <br />portion of wetland area and 85 feet adjacent to the east and west portions. The <br />proposed buffer plan results in approximately 167,200 s.f. of buffers, slightly over <br />the minimum MCWD requirement of 166,400 s.f. <br />The City code requires a minimum structure setback of 35’ from the wetland <br />boundary, plus 10’ additional where the 35’ setback would be less than 10’ from a <br />MCWD required buffer. The City will require a Conservation and Flowage <br />Easement over the wetlands being preserved. <br /> <br />14. Tree and/or Woodland Impacts. The portion of the site being developed contains <br />a variety of mature tree species including deciduous hardwoods (oak, maple, ash, <br />linden and walnut) as well as white pines, scotch pines and spruce. Approximately <br />115 trees were inventoried within the anticipated limits of grading, and virtually all <br />inventoried trees are anticipated to be removed as a result of the development. <br />Outside the development area, along the perimeter of the landfill area, a majority <br />of trees are volunteer weed trees consisting mainly of box elder, with buckthorn <br />invading at the southern boundary of the site. The Conservation Design Master Plan <br />calls for removal of the buckthorn from “Area B”, while the hackberry and other <br />tree species will be allowed to remain as a visual and sound barrier from the <br />Highway 12 corridor.
