The landscape plan proposes Snowdrift Crabapple and Red Splendor Crabapple. Both varieties set fruit that persists into the winter and are good choices in sunny well drained areas where Crabapple trees are appropriate. A few of the Snowdrift Crabapple trees are shown in areas that may be too moist or shady. Alternative species such as the Serviceberry or Page !u Dogwood should be considered in those locations. The landscape plan proposes planting 4 Colorado Spruce, 8 Black Hills Spruce, 7 Amur Maple, and 1 Snowdrift Crab along the open area in the northwestern part of the site. As these plants mature they should provide adequate buffering to the north. However, the grading plan shows a small drainage basin In the central part of the northorn area. Plants in this area should be located outside of the basin. In addition, all plants should be located out of any swale or drainage ways. Plants located near drainage ways and holding areas should be species that are tolerant of moist conditions such as Swamp White Oak, Hackberry, Red Maple, River Birch, Serviceberry or Pagoda Dogwood. This project will remove the existing trees from the outer edge of the woods in several areas. The remaining larger trees in those areas will be especially susceptible to wind throw and storm damage after the woods is opened up. When completed, the town home units will help protect these exposed edges. Additional new trees should be planted where needed to protect and reinforce the newly exposed wooded edge. *• % • .1 This project is proposing saving a number of significant trees and large areas of woods and open space. As noted In our prior review, it is imperative that all trees and wooded areas to be preserved are protected by fencing at the drip line prior to beginning construction. In addition, good construction management and arborist practices must be observed to minimize the potential for the infection and spread of oak wilt. In addition, there must be appropriate authority to stop work and recourse for correcting damages, in the event that these practices are not adequately observed. 10.As noted during prior reviews, the proposed NURP basin will be visually prominent when viewed from County Road 15 and Livingston Avenue, and should be constructed to serve as a visually attractive natural feature. Additional native tree and shrub groupings should be planted In appropriate locations around the perimeter of the pond to enhance its value as a natural amenity. Rip rap should be placed to achieve a natural rather than utilitarian appearance. -4- * • L
