13. Tree Preservation Plan. The DEVELOPER is required to submit a Plan for CITY approval <br /> that identifies existing tree growth within the Plat that will be protected during construction, <br /> and identifies the location and species of any new plantings. The trees to be protected must <br /> be identified on the plan, and the plan must require the installation of 'tree save fences' prior <br /> to land clearing or grading. The submitted Tree Preservation exhibit shall satisfy this <br /> requirement. In addition, the requirement for this Plan shall be fulfilled by the <br /> DEVELOPER as follows: <br /> <br />a) <br /> <br />Minimizing the impact of construction on trees in accordance with Minnesota <br />Extension Service publication "Protecting Trees From Construction Damage" <br />(Publication #NR-FO-6135-S). <br /> <br />14. Tree Disease Prevention and Disposal. The DEVELOPER shall prevent the introduction <br /> and spread of tree disease into the residual tree populations of the Plat and adjoining <br /> properties as well as mitigate the effects of construction activity on tree health, within and <br /> outside of the Plat. The DEVELOPER, in order to protect trees from construction damage <br /> shall: <br /> <br />a) Install physical barriers, such as snow fence, around trees that are to remain after <br /> initial grading. The fencing shall be located at the dripline of these 'save' trees. <br /> <br />b) <br /> <br />Insure that all equipment operators will have readily aVailable, a tree wound dressing <br />and will apply it immediately to damaged oak trees if wounding occurs from April 15 <br />through July 15. <br /> <br />c) <br /> <br />Insure that trees will only be skidded against other trees that are to be removed. <br />Trees in the middle twenty (20) feet of a road easement will be removed first, with <br />remaining trees to be skidded toward the middle of the road easement. This same <br />procedure will apply to building sites. <br /> <br />d) <br /> <br />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 <br />shattering, scraping and exposure of roots of high value trees on adjoining property. <br />All exposed root zones of adjoining properties shall be immediately covered with <br />clean topsoil and moistened to favorable conditions. <br /> <br />e) <br /> <br />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) <br />business days prior to destruction. <br /> <br />Tree wood removed during construction, road building and sewer/water installation <br />shall be buried, burned, chipped or hauled to a licensed wood disposal site~ Wood <br />waste disposal must take into account tree disease control, especially for oak wilt and. <br />Dutch Elm disease. The CITY will perform a site inspection to ascertain tree disease <br />hazards (including root damage and grade changes) prior to construction in order to <br /> Development Agreement/Riverbrook <br /> Page 5 of 8 <br /> <br /> <br />
