Sam Oakley 231 Old Bernal Avenue Tree Inventory, Valuation, and Construction Guidelines 9/13/2024 1 PO BOX 2412 PISMO BEACH, CA 93448 (415) 407-6995 SAM@OAKLEYGROUP.ORG WWW.OAKLEYGROUP.ORG Introduction The 231 Old Bernal Avenue property in Pleasanton, California, is a commercial property proposed to have one (1) 3-story building installed. For the project to commence, a tree survey and valuation is required by the City of Pleasanton’s Tree Preservation Ordinance Chapter 17.16 is required for trees that are within the immediate area of the project. We were retained as project arborist and were issued the plans for the project. Assignment The tree survey was performed as a requirement for plan submittal. The survey provides individual analysis of tree health, and the expected impacts of proposed construction, and tree value as well as guidelines for tree protection for trees proposed for preservation. An inventory of all protected trees with a diameter of 4 inches was performed in July 2024 for individuals whose trunks were within fifty (50) feet of the proposed grading, trenching, and other improvements. All trees inventoried were numbered for identification purposes and were identified as to whether individual trees will require removal or alteration based on the design of the project. A tally of trees proposed for removal and their respective aggregate trunk circumference sizes was prepared. The location of each individual was determined and marked in the site plan contained in Exhibit 1. Data collected per individual tree for the inventory are as follows: number, scientific name, common name, diameter and circumference at fifty-four (54) inches above grade, location, condition, and any observational notes (see Exhibit 3). Action, suitability for preservation, and impacts from construction were evaluated after the inventory. In addition to the inventory results, construction guidelines are provided in this report. Included in this report are the inventory map (Exhibit 1), and the tree inventory matrix (Exhibit 2). Limits Note that the recommendations in this report are based on visual inspection on the above- ground parts of the tree at the time of the site visit. No soil was removed for below-grade inspection and no aerial inspection was performed. Deciduous trees had a natural absence of foliage due to the seasonal loss of foliage, and condition was not based on leaf tissue appearance or color. Information in this letter may warrant further investigation as site conditions change over time. Page 335 of 373
