Tree Preservation and Mitigation Standards The Environmental Coordinator’s Memo dated March 1, 2023 addresses tree preservation and landscaping. All tree removals planned for this project are within the basic use area. A survey, tree preservation plan, and mitigation plan will not be required for this project. Open Areas Landscape Standards The open space for this project is the approximately 4,000 sq.ft. in and around the stormwater infiltration basin west of the proposed parking lot. This would require 2 large trees and 4 large shrubs. There are shrubs and trees provided along the fence to the south of the parking lot that exceed the requirements for screen planting. The additional plants along the fence will satisfy the open space planting requirements. Open space planting requirements have been met. Buffer and Screen Standards A 6 foot fence with trees and shrubs is proposed to provide continuous, year-round screening between the parking lot and the residential lots to the south. Buffer and screen standards have been met. Canopy Cover Canopy cover standards call for a minimum of 40% canopy coverage. Canopy coverage values are calculated per tree based on the anticipated size, 15 years after planting, and the distance to hardscape edge from the planting location. Vehicular hardscape planned: 42,662 sq. ft. Canopy cover requirement: 17,064 sq. ft.
