INC.@002/005 2. 3. 4. for 3 inch caliper deciduous overstory trees, 2 inch caliper deciduous ornamental trees, 6 feet high evergreen trees, 3 feet high deciduous shrubs, and for lawn areas other than natural areas to be sodded. The plant sizes shown on the landscape plan include overstory deciduous trees from 8 feet high to 2 • 2 % inch caliper, ornamental trees from 5 feet high to 1 1/4 inch caliper, evergreen trees from 5 to 6 feet high, and shrubs from 16 to 18 inches high. These sizes are less than called for in the ordinance. We recommend increasing the number of plants and allowing the following reduced minimum sizes: deciduous overstory trees • 2 inch caliper, deciduous ornamental trees - 11/2 inch caliper, and deciduous shrubs - 18 inch high. Evergreen trees should be 6 feet minimum height. If handled and planted^ properly, the smaller plants will have a shorter transplanting recovery period, reduced loses, and should perform better than the.larger material. We recommend a 30 percent Increase in the number of deciduous overstor/ and understory trees. These additional trees should be located within the unplanted larger islands between units, along the southern drive and along the northern edge of the proposed NURP basin. We also recommend a 100 percent Increase In the number of shrubs. These shrubs should be located In parking Islands and foundation plantings. The landscape plan does not identify the condition of the proposed plants. All plant materials are to be nursery grown, disease and injury free, vigorous, first class selections of their species. All trees are to be first quality (not park grade) balled and burlapped. Shrubs are to be container grown. The planting details, landscape specification, seed and sod specification, and warranty and maintenance provisions are to be reviewed and approved by the City. This information is to include the provisions that will be made for watering/irrigation and maintenance of the landscaping and lawns through construction and after project completion. Approval of the landscape plan should be subject to a final review and adjustment after the tree removal, grading and rough framing have been completed in order to determine the need for adjusting planting locations to provide adequate screening/buffering. The drives, parking and garage fronts will be visually dominant along Livingston and the private drive serving the southern units. The islands between garages are approximately 4 feet wide, too narrow for growing and maintaining trees in a healthy undamaged condition. The landscape plan proposes only two shrubs (Emerald Mound Honeysuckle) and a rock mulch ground cover in each of these islands. The rock mulch strips and lack of -2-
