Tree Preservation The Environmental Coordinator and Environmental Board reviewed the tree preservation and landscape plans. The goal of tree preservation is to minimize unnecessary loss of habitat, biodiversity and forest resource and to replace removed trees in areas where tree cover is most critical. The Tree Inventory Report prepared by Carlson McCain revised January 10, 2020 identifies 750 significant trees on site. Eighty-eight (88) trees were identified as non- significant (e.g. ash trees, elm trees etc.) and will be removed without mitigation requirements. Of the remaining 662 trees, 252 trees will be saved and 410 will be removed. Sheet T4, Tree Preservation Plan identifies the basic use area and environmentally sensitive areas. Five (5) trees are being removed within the natural resource conservation area. Fourteen (14) trees are being removed from the non -ESA and non -basic use areas. This requires 29 replacement trees for mitigation which are provided throughout the development. Landscaping Open area landscaping standards require 1 large tree and 3 large shrubs per 2,000 sf. Existing trees on site may be used to satisfy open area landscaping requirements if applicable by placement. This would only apply to the existing trees on Outlot A. The landscaping plan has been revised to provide adequate open space mitigation for Outlots B, D and E. Outlots C does not require mitigation because it is for future right -of way. Buffer and screen standards apply along CSAH 54 (20th Avenue), specifically Block 4, Lots 12-15 that have a rear frontage on 20th Avenue. Approximately 475 linear feet of frontage will be screened by shrubs, new trees, and existing trees to provide a continuous planting screen year-round. The Preliminary Landscape Plan shows trees and shrubs planted on two separate berms. It was suggested these berms be combined to provide a continuous berm; however, an opening between the 2 berms is needed to provide rear yard drainage. A triangulated row of coniferous trees will be planted in addition to the berms that will provide appropriate screening. A triangulated row of coniferous trees will also be planted at the north end of Heritage Avenue to screen potential vehicle headlights shining onto the adjacent property. Coniferous trees and shrubs will be planted on Outlot F around the lift station. Boulevard trees are required at the rate of one (1) tree per lot frontage for single family. There are 68 single family lots that require 77 boulevard trees (interior and corner lots). Seventy-nine (79) trees are proposed which is compliant with the ordinance. 11
