Pre!.iminary Plat and Site Plan Review <br />Shade Tree Cottages <br />April 1, 2005, revised May 6, 2005 <br />Page 4 oi'6 <br /> <br />several a~.-ea~5 where the wetlands will be impacted by construction. A sequencing plan for the impacts and <br />mitigation must be approved by the Lower Rum River WMO. <br /> <br />The preliminary plat is providing for a "No Mow" zone along the wetlands located within the single family <br />lots. This will help future home owners to fully understand where they must stop manicuring their yard in <br />or'der to protect the wetlands. The City is working on establishing a wetland buffer ordinance. Staff will be <br />recommending that the development implement some of the seeding .specifications published by M. nDot <br />within the no [now zone. <br /> <br />12. Traffic Generation Analysis. A traffic generation analysis for this project was completed by Bolton and <br /> Menk /nc. The traffic study shows that the additional traffic generated from this development will not <br /> degrade the operations of the existing streets and intersections. As part of th_e studY, Bolton and Menk made <br /> the., fi~llowing recommendations: <br /> <br />a. Place a stop sign at the northbound approach of Radium Street and 157th Lane <br />b. Place a stop sign at the southboUnd approach of Potassium Street and Old CSAH 5 <br />c. Upgrade Potassium Street to provide a paved surface and adequate width <br />d. Upgrade width and roadway surface of Old CSAH 5 <br /> <br />Drainage and Utility Easements. Wetlands must be encumbered with a drainage and utility easement. It <br />appears that the preliminary plat complies with this requirement. <br /> <br />l)ensi~ Transitioning. The proposed development is bounded by properties. zoned R-1 Rural Developing <br />to the north and thus must provide some sort of transitioning along this common property line. The revised <br />landscaping plan, dated April 14, 2005 indicates that a combination ofberming and landscaping will be used <br />to fulfill, the transitioning requirements. The buffer strip should be thirty-five (35) feet in width and contain <br />a combination of overstory and understory deciduous trees and coniferous trees. The revised landscaping <br />p!an appears to comply with the density transitioning requirements. <br /> <br />Landscaping. The revised landscaping plan, dated April 14, 2005 is generally acceptable. <br /> <br />i6. Tree Preservation. There are over 600 trees that are to be preserved throughout the construction process <br /> cor~sisting mostly of aspen, red cedar, bur oak and red oak. Furthermore, Lots 32-35 are to be custom <br /> graded, which will provide an opportunity to preserve additional trees. Tree save fencing is required aroUnd <br /> all trees or groups of trees to be preserved. The fencing shall include, at a minimum, the entire area beneath · <br /> the tree canopy, which is known as the critical root zone. No construction activity whatsoever may occur <br /> within these areas. Moreover, no construction shall, begin until this fencing has been installed and approved <br /> by the City. <br /> <br />Finally, any c~earing involving oak trees cannot occur between April 15 and July 15 to protect against oak <br />wilt. II' oak trees exist on or adjacent to the development area, a plan must be submitted outlining the <br />actions that will be taken to protect those trees from oak wilt. <br /> <br />-131- <br /> <br /> <br />
