Tree Report. December 7, 2020. <br />Hidden Canyon (Lester property). Ponderosa Homes. <br />Tree Preservation Guidelines <br />HortScience I Bartlett Consulting <br />Page 20 <br />The following are recommendations for design and construction phases that will assist in <br />successful tree preservation. <br />Design recommendations <br />1. Locate the trunk of all trees recommended for preservation that are located within <br />25' of the edge of grading and/or utility installation. Include trunk locations and <br />tree tag numbers on all plans. <br />2. Establish a TREE PROTECTION ZONE around each tree to be preserved. For <br />design purposes, the TREE PROTECTION ZONE shall be 3' behind the edge of <br />grading. No grading, excavation, construction or storage of materials shall occur <br />within that zone. <br />3. Install protection around all trees to be preserved. No entry is permitted into a <br />tree protection zone without permission of the project superintendent. <br />4. Use only herbicides safe for use around trees and labeled for that use, even <br />below pavement. <br />Pre-construction and demolition treatments and recommendations <br />1. The demolition contractor shall meet with the Consulting Arborist before <br />beginning work to discuss work procedures and tree protection. <br />2. Trees to be preserved may require pruning to provide adequate clearance from <br />construction activities. All pruning shall be performed by a licensed State of <br />California contractor possessing the C61 classification license and the D49 <br />specification. All pruning shall adhere to the latest editions of the American <br />National Standards Institute 2133 and A300 standards. <br />3. Install tree protective fencing at the edge of the TREE PROTECTION ZONE. No <br />grading, construction, installation or other activity is permitted within this area. <br />4. Stake the edge of grading along the EBRPD access road in order to review <br />impacts to trees. <br />Tree protection during construction <br />1. Prior to beginning work, the contractors working in the vicinity of trees to be <br />preserved are required to meet with the Consulting Arborist at the site to review <br />all work procedures, access routes, storage areas and tree protection measures. <br />2. Any grading, construction, demolition or other work that is expected to encounter <br />tree roots should be monitored by the Consulting Arborist. <br />3. If injury should occur to any tree during construction, it should be evaluated as <br />soon as possible by the Consulting Arborist so that appropriate treatments can <br />be applied. <br />4. Fences have been erected to protect trees to be preserved. Fences are to <br />remain until all site work has been completed. Fences may not be relocated or <br />removed without permission of the project superintendent.
