City of Pleasanton—Villages at the Quarry Project <br />Consistency Checklist 15183 Consistency Checklist <br /> <br /> <br />92 <br />COA BIO-2 Temporary Protective Fencing, Tree Protection Zones <br />To assure against intrusion into root zones by material storage or <br />construction equipment, temporary protective fence will be <br />required, and will be shown on the referenced drawing. This <br />fencing will be intended to provide sufficient room for <br />construction activity while protecting root zones and will define <br />the Tree Protection Zone (TPZ). All such fencing will protect trees <br />on neighboring properties. <br />There must be no disposal of waste or equipment washout that <br />could drain off-site into the protected zone. The fencing should <br />be minimum 5-foot chain-link securely fastened to the ground or <br />on driven posts, to prevent casual displacement by site workers <br />who may not understand its purpose. The location shown on the <br />drawing should be reviewed on-site to the satisfaction of both <br />the Arborist and the General Contractor or site supervisor. <br />Each fence section must have 8.5-by-11-inch plasticized signs <br />fastened every 50 feet, reading, “THIS FENCE MAY BE MOVED <br />ONLY WITH PERMISSION OF THE PROJECT ARBORIST.” A template <br />sign is attached to this report. Fencing to protect retained trees <br />should be in place as shown before any grading, construction or <br />other site work begins. Fencing should remain in place during the <br />entire demolition, grading, or construction phases and should <br />not be moved by any subcontractor for any reason, without <br />approval of the Project Arborist. <br />Fencing to protect retained trees must be in place as shown <br />before any demolition, grading, construction or other site work <br />past layout begins. Fencing shall remain in place during the <br />entire demolition, grading or construction phases and shall not <br />be moved by any subcontractor for any reason, without <br />approval of the Project Arborist. <br />COA BIO-3 Mulching Under Trees <br />Mulch is highly beneficial for trees being preserved. The ideal, <br />and by far the most beneficial supplemental or replacement <br />mulch for the trees, is chips from a tree service. This mulch can <br />be a permanent feature of the landscape, and a maintained <br />depth of four inches over as much of the rootzone as is
