Attachment_1_URBAN_TREE_PLANTING_-_PLANS.pdf

This document is a comprehensive urban tree planting design plan for Independence National Historical Park in Philadelphia, Pennsylvania. The plan encompasses multiple locations within the historic district, including Washington Square, Independence Square, the Second Bank Block, Merchant's Exchange Block, Liberty Bell Center, Independence Visitor Center, Magnolia Garden, and Franklin Court, with detailed specifications for tree species, quantities, sizes, spacing, and planting schedules.

The design includes a total of 11 sheets detailing tree locations across multiple site blocks, landscape details, and tree pit expansion plans. Tree species are specified by botanical and common names with corresponding sizes (measured in caliper inches and height in feet), spacing requirements (ranging from 1.5 to 5.0 feet), and planting locations. Key tree species include Red Maple, Eastern Redbud, Cornus species, Sugar Maple, Emerald Arborvitae, Littleleaf Linden, Southern Magnolia, Saucer Magnolia, Ginkgo, and various oak species. The plan provides both base planting options and optional expansion plans, with detailed landscape details including longitudinal sections, cross-sections, tree pit specifications, soil preparation methods, and root ball preparation procedures. All proposed tree locations are designated for on-site approval prior to installation, with archaeological monitoring required during the project. Scale notations of 3/8" = 1' are provided for reference, and the document was prepared by the United States Department of the Interior National Park Service.
