Preliminary Plat: Skyline Pointe June 30, 2006 Page 3 of 8 Landscaping: A combination of existing trees and new plantings are proposed to satisfy the planting requirements. New plantings will account for about 80,000 square feet of the required 151,406 square feet of canopy cover. The following co=ents are offered regarding the landscaping plan, dated June 23, 2006: o The square footage designated for individual species in the planting schedule is not accurate, but, due the combination of existing trees and new plantings will satisfy the planting requirements. The following table reflects the canopy allocations for the indicated species: S oecies Ouantity CanODY Allocation Total Canony Coyer Pinus strobus 10 1,995 19,950 Thuia oecidentalis 6 626 3,756 LarL-c laricina 3 718 2.154 Quercus bieolor 20 718 14,360 Celtis oecidentalis 2 922 1,844 Betula alle"haniensis 12 922 11,064 Ulmus;c 'Cathedral' 10 5-7 5,520 J_ Sorbus decora 40 336 15,440 Populus '<7'andidentata 20 319 6,330 Totals 123 80,468 o Additional evergreens need to be incorporated into the plan. At least 25% of the required landscaping must consist of evergreens. o At least one or two additional ornamental tree species need to be included in the plan for species diversity purposes. While the overall number of ornamental trees does_ not necessarily need to be increased, the number of ornamental species installed must mcrease. o While the tree save fencing is noted in the comments, it should be shown on the landscaping/preservation plan and must be in place prior to any construction activity on the site. o Planting depth shall be such that the root flare shall be at grade level. Please submit a revised landscaping plan that addresses these concerns. Density Transitioning: The preliminary plat proposes to construct townhomes adjacent to single-family homes, and requires density transitioning. City Code allows for a variety of measures to satisfy the density transitioning requirements. If landscaping is used to fulfill this standard, then Levell transitioning is required. A minimum of six (6) trees for every 100 feet of adjacent property, including two each of evergreens, overstory trees, and ornamental trees, are required along portions of the western and southern boundaries of the parcel. Tne areas subject to the transitioning requirements span approximately 500 feet and thus would require a minimum of thirty (30) trees. A combination of existing trees and new plantings are proposed for transitioning purposes. This combination appears to satisfy the minimum number of trees 15
