Identify the species and measure the trunk diameter of each tree with a diameter of 6 inches or greater within the project area (approximately 600 trees).Trunk diameter shall be measured at 54 inches above grade. 2. Tag each tree with a metal tag for identification purposes.Off-site trees overhanging the property will be numbered but may not be tagged. 3. Visually evaluate the health and structural condition of each tree. 4. Identify any trees having special status(Heritage) in Pleasanton. 5. Rate tree suitability for preservation based on their health,structural condition and potential longevity and suitability in the landscape. 6. Take representative photos. 7. Evaluate the impacts of proposed project on trees based on site improvement plans provided by the client. 8. Estimate trees that will be preserved and removed based on construction impacts and tree suitability for preservation. 9. Prepare a Tree Inventory Map showing approximate location of trees by tag number. 10. Prepare Tree Preservation Guidelines outlining protection measures during the planning, demolition and construction phases of development to meet City of Pleasanton requirements. 11. Appraise the value of each tree using the methods described in Guide for Plant Appraisal, 10th Ed., International Society of Arboriculture, 2018. 12.

Geotechnical Investigations As a subconsultant to Mark Thomas,Crawford &Associates, Inc(Crawford) understands the City of Pleasanton (City) plans to reconstruct West Las Positas Boulevard (WLP) between Foothill Road and Fairlands Drive (approximately 2.75 miles) based on the plans completed by Toole Design and Mark Thomas,dated April 2020. Past roadway work,and geotechnical studies completed by Kleinfelder, ENGEO, Inc(ENGEO),and BSK and Associates (BSK)are summarized below.The City is seeking help during design and implementation of the improvements scheduled to start construction in summer 2024. To address the roadway improvements and support the team during final design,Crawford proposes the scope of services below. Coordination,Kickoff, Field Preparation and Permitting • Meet with the design team to review the rehabilitation and/or reconstruction concepts and discuss the project design needs,goals, and schedule; • Review available pavement maintenance records; • Determine exploration locations, determine site access,and mark our locations for USA; and • Obtain a City of Pleasanton Encroachment Permit, if needed. Subsurface Exploration Crawford understands that significant geotechnical work has already been completed by BSK for WLP between Hopyard Road and Stoneridge Drive (approximately 1.2 miles)and additional work is not proposed. Between Foothill Road and Hopyard Road,and Stoneridge Drive and Fairlands Drive (approximately 1.5 miles total), City staff will review and note the pavement condition to identify potential dig out/failed pavement locations for inclusion in the plans. Crawford proposes to perform pavement coring at eight to ten locations to determine the existing HMA and AB thicknesses to support the rehabilitation strategy within these areas. Based on discussions
