<br /> Pre-construction treatments and recommendations
<br /> 1. The construction superintendent shall meet with the Consulting Arborist before
<br /> beginning work to discuss work procedures and tree protection.
<br /> 2. Four the four remaining Bradford pear trees, a TREE PROTECTION ZONE should be
<br /> established at the dripline on the 218 Ray Street side of each tree.
<br /> 3. Protect the trunk of the pecan (tree#7) by wrapping wattle around the trunk from the
<br /> height of the fence to 18'.
<br /> Recommendations for tree protection during construction
<br /> 1. No grading, construction, demolition or other work shall occur within the TREE
<br /> PROTECTION ZONE. Any modifications must be approved and monitored by the
<br /> Consulting Arborist.
<br /> 2. Grading within the dripline of any tree shall be monitored by the consulting arborist.
<br /> 3. Supplemental irrigation shall be applied as determined by the Consulting Arborist.
<br /> 4. If injury should occur to any tree during construction, it should be evaluated as soon
<br /> as possible by the Consulting Arborist so that appropriate treatments can be applied.
<br /> 5. No excess soil, chemicals, debris, equipment or other materials shall be dumped or
<br /> stored within the TREE PROTECTION ZONE.
<br /> 6. Any additional tree pruning needed for clearance during construction must be
<br /> performed by a Certified Arborist and not by construction personnel.

<br /> Tree Preservation Guidelines
<br /> Certain trees will be designated for preservation based on their suitability for preservation and
<br /> location relative to the development plan. Once those decisions have been made, the
<br /> following recommendations will help reduce impacts to trees from development and maintain
<br /> and improve their health and vitality through the clearing, grading and construction phases.
<br /> The goal of tree preservation is not merely tree survival during development but maintenance
<br /> of tree health and beauty for many years. Trees retained on sites that are either subject to
<br /> extensive injury during construction or are inadequately maintained become a liability rather
<br /> than an asset. The response of individual trees will depend on the amount of excavation and
<br /> grading, the care with which demolition is undertaken, and the construction methods.
<br /> Coordinating any construction activity inside the Tree Protection Zone can minimize these
<br /> impacts.
<br /> 218 Ray Street is an already-developed site. Tree roots will be protected from damage by the
<br /> existing parking lot pavement. Above-ground portions of the trees are subject to damage by
<br /> construction vehicles and equipment.
<br />are better
<br /> able to generate new tissue and respond to change. The potential longevity of the
<br /> Monterey pines is low because of the mature age and infection with pitch canker.
<br /> generally are unsuited for use areas.
