_____________________________________________________________________________________________ City of Arden Hills Planning Commission Meeting for April 5, 2017 P:\Planning\Planning Cases\2017\PC 17-008 - Lexington Station - Master PUD Amendment and Final PUD Phase 2\Memos_Reports_17-008 Page 7 of 17 Caliper Inches Number of Trees New Trees for Phase 2 Building 53.1 -- Proposed Significant Tree Removal 63 3 Mitigation Requirement 28 -- Total New Tree Plantings 81.1 -- Proposed Tree Plantings 84 25 The Zoning Code requires that the minimum total caliper inches include a certain percentage of trees in various size ranges based on the building height in stories. The Phase 2 building is one- story in height and 50 percent of the new trees would need to be 2.0” – 3.0” in size, 30 percent 3.5” – 4.0”, and 20 percent 4.5” – 6.0”. The landscape plan indicates the new trees for the Phase 2 building would satisfy this requirement. Trees along Street Frontage – Exceeds Requirements The City Code requires that a minimum of one tree be planted along the right of way for every 40 feet of street frontage. Phase 2 will have approximately 259 feet of frontage along Red Fox Road. A total of 7 trees along the right of way are required. The Landscape Plan shows 9 trees along this street frontage. Perennials and Shrubberies – Meets Requirements The City Code requires that at least ten percent of the total landscaped area shall be covered with perennials and/or shrubbery. This requirement is evaluated with each phase as the developer proposes a detailed landscape plan. The Master Plan has 65,760 square feet of landscape coverage, of which 6,576 square feet will be required to be planted with perennials. Phase 1 of the development included 2,824 square feet of plantings and Phase 2 will include 402 square feet for a total of 3,226 square feet. With Phase 3, the developer will need to provide an additional 3,350 square feet of perennial or shrubbery plantings to meet the ten percent planting requirement. Planting Islands – Flexibility Requested At least ten percent of a parking area must be occupied by planting islands that are at least 150 square feet in size and have at least one tree. The planting islands appear to meet the size requirements and all islands include a tree or perennial plantings. The proposed amendment would increase the portion of the parking lot comprised of planting islands from 9.3 percent to 9.95 percent. Tree Selection – Meets Requirements The proposed Maple, Aspen, Linden, and Crabapple trees are appropriate for urbanized locations and should grow in their proposed locations.
