a. Install physical barriers, such as snow fence, around trees that are to remain. The fencing <br />shall be located at the dripline of these remaining trees. <br />b. Insure that all equipment operators will have readily available, a tree wound dressing and <br />will apply it immediately to damaged oak trees if wounding occurs from April 15 through <br />July 15. <br />c. Insure that trees will only be skidded against other trees that are to be removed. Trees in <br />the middle twenty (20) feet of a road easement will be removed first, with remaining trees <br />to be skidded toward the middle of the road easement. This same procedure will apply to <br />building- sites. <br />d. Mature trees, especially oak and elm, adjoining an easement so that roots enter the <br />disturbed construction area shall first be severed by a vibratory plow to prevent shattering, <br />scraping and exposure of roots of high value trees on adjoining property. <br />e. Recognized trees of value, suitable for tree spade removal that would otherwise be <br />destroyed, shall be identified with ribbon and offered to the CITY at least five (5) days <br />prior to destruction. <br />f. Tree wood removed during construction, road building and sewer /water installation shall <br />be buried, burned, chipped or hauled to a licensed wood disposal site. Wood waste <br />disposal must take into account tree disease control, especially for oak wilt and Dutch Elm <br />disease. The tree inspector needs to make a site inspection to ascertain tree disease hazard <br />prior to construction in order to minimize impact on trees adjoining easement, (including <br />root damage and grade changes) and for disease control. An inspection to reduce or abate <br />wood waste disposal must also manage air quality impact and smoke nuisance to adjoining <br />property owners as well as fire safety concerns. <br />Whole trees may not be disposed of by burning. Trunks and limbs larger than six (6) <br />inches in diameter must be salvaged for lumber, firewood, chipped or hauled to a licensed <br />wood disposal site. Application may be made for an open burning permit to dispose of <br />brush less than six (6) inches in diameter and stumps with less than four feet of main <br />trunks attached. The location of the proposed open burn site will be specified by the City <br />Engineer, Environmental Specialist and Fire Chief. Wood disposal by burning requires <br />whole tree volume reduction, proposed site inspection prior to clearing and an open <br />burning permit. Residual ash and unburned stumpage may be buried on the site at the <br />direction of the City Engineer. Chipped material may be applied and utilized on site to <br />mitigate root damage from grade changes of the easement or right -of -way and for erosion <br />control and top soil restoration. <br />91 <br />
