According to the Code, the City has the exclusive authority to plant, remove, prune, inspect, maintain, root prune or otherwise alter rights-of-way trees. A total of 157 trees were inventoried on and adjacent to the subject property. Of the 157 trees, 37 are considered rights-of-way trees and the remaining 120 are private property trees that are not “protected” by the City Code. Off-site trees on contiguous properties that may be affected by the construction of the proposed project are included in the inventory. BACKGROUND AND ASSIGNMENT The Compton Unified School District (CUSD) is proposing the reconstruction of the entire campus. The 157 inventoried trees are located throughout the property. We were retained to visit the property and inventory and photograph all private property trees and City rights-of-way regardless of size. A comprehensive analysis of each tree as it pertains to construction was not requested and is not a part of this study. This report is based on our site visit of February 27, 2018. OBSERVATIONS We inventoried 157 trees of various species. Tree trunks were recorded in the field, from grade, using Dulin & Boynton’s Topographic Map (August 10, 2000). The on-site trees were numbered and tagged with an embossed aluminum tag. Table 1 summarizes the inventoried trees and their protected status. Captioned photographs and exhibits at the end of this report illustrate site context, tree locations, tree structure, and vigor. A full-sized copy of the ‘Tree Location Exhibit’ is included in back pockets at the end of this report. CONCLUSION Once the design is finalized, CUSD may request an analysis of construction impacts to each tree and recommendations for protection of trees during the construction process. We are available to provide a proposal for this study as requested; this assignment was only for a site analysis.
