The Landscape Plan shows a total of 27 caliper inches of new trees. Caliper Inches Number of Trees Total Existing Significant Trees 761 80 Permitted Removal (10% of Existing) 76.1 -- Proposed Significant Tree Removal 76 3 Mitigation Requirement 0 0 New Trees for Building Addition 26.7 -- Proposed Tree Plantings 30.5 10 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.
