Shade Tree Creek Preliminary Plat Review April 21, 2006 2of5 are needed to fulfill the density transitioning requirements (roughly 120 along Lots 1-6, Block I, and 120 along Lots 1-3, Block 3, including both the north and east sides of Lot 1 .) The Landscape Plan indicates that 148 trees will be installed for the purposes of density transitioning. This is deficient of the minimum requirements by 92 trees. All proposed species are acceptable. However, minimum plant size for transitioning purposes is 2.5 inches for overstory, 1.5 inches for ornamental, and 6 feet for evergreens. Additionally, more ornamental species should be included (white pine and black hills spruce are not ornamental). As noted on the Landscape Plan, there is a power easement across the northern portion of the site. Any plantings would be subject to the approval of the easement holder. This does raise a concern regarding the proposed vegetation, which is intended to provide for transitioning between existing homes and the proposed lots. Therefore, if landscaping is used as density transitioning, it will be necessary to obtain an a~eement with the easement holder that the proposed plantings will not be removed in the future as part of their regular vegetation management program. A revised Landscape Plan is necessary. Also, Section 9.20.11 states that the location of the proposed lots shall be arranged giving consideration to the location of existing houses, and other factors as required by City Council. The proposed plan sites homes on common property line with 2 adjacent neighborhoods, intensifying the negative effects on the existing neighborhood. The Planning Commission and City C~xancil have expressed concern r~garding this issue in past meetings. Landscaping Plan: The Landscape Plan, dated April 5, 2006, regarding the front yard plantings is acceptable. Tree Preservation Plan: The Tree Preservation Plan, dated April 5, 2006, is generally acceptable to City Staff. Prior to the commencement of site work, tree save fencing must be installed around individual trees and/or groups of trees. Fencing shall be installed at the dripline of trees, not around the base of trees. Where feasible, efforts should be made to preserve trees that are outside of the indicated preservation area. Finally, due to the presence of oak trees on and adjacent to the development area, a plan must be submitted outlining the actions that will be taken to protect those trees from oak wilt. Any clearing involving oak trees cannot occur between April 15 and July 15 to help protect against oak wilt. Existing Structures: Any structures proposed to remain must conform to the general building orientation and driveway direction as the newly created lots. It appears that Lot 12, Block 1 is proposed to be oriented differently than the new houses. Facades improvements or other methods to reorient the existing house will be required as part of final plat. 45
