2. The PDO narrative describes the streetscape landscaping. In review of this information, the following issues have been raised: a. The PDO narrative has been revised to indicate that tree spacing for public and private roads will generally be three trees per 100 feet of curb length. Parking lot islands will have at least one tree with a minimum three inch caliper. No graphic plan has been provided that shows the quantities, locations or spacing of streetscape trees. b. No plant schedule is offered for the PDO, however, some plant sizes are described in the PDO narrative. The PDO narrative states that, "Replacement trees will include overstory trees with a minimum three -inch caliper, or deciduous trees having a minimum height of eight feet." This statement should be revised to the following: "Replacement trees will consist of overstory trees with a minimum three -inch caliper, or evergreen trees having a minimum height of eight feet." c. The PDO narrative has been revised to indicate that native grasses and wildflowers will be emphasized in the eastern portion of the site (near Wetlands 2 and 3), along the 1 -35 corridor, and along infiltration areas. These are appropriate locations for native grasses and wildflowers. d. The site plan for Phase 1 has been revised to not include amur maple trees, however the PDO narrative states that small groves of multi -stem amur maples will be planted along Apollo Drive and private roads. The use of amur maples as a boulevard tree raises issue with regard to traffic sight lines. Also, amur maples are native to Asia and can become invasive in natural areas in the Midwest. A native species, such as cockspur hawthorn, would be more desirable if a small tree is needed. 3. Streetscape Along CSAH 23. The Town Center Planning District recommends the establishment of a streetscape treatment along CSAH 23 that will provide design connection between each quadrant of the Town Center interchange. The design parameters for this public improvement has not yet been established to allow for a continuous streetscape design between CSAH 23 and Apollo Drive. These streetscape elements are currently under study. The streetscape elements between Apollo Drive and CSAH 23 should be integrated with one another. Tree Preservation. The PDO narrative states that tree preservation is recognized as a major concem of the City. The narrative also states that sight lines are essential for retail development and some tree removal is unavoidable. The applicant has proposed that for each of the 275 identified trees (not including Elm or Boxelder) that is removed as part of the PDO development, a 1 -for -1 tree replacement plan be provided.
