Utility installation within the dripline of protected trees, during construction or thereafter, can only occur using trenchless methods. • The mowing, clearing, and grubbing of brush located within or under the dripline of protected trees may be allowed, provided such mowing, clearing, or grubbing is accomplished by hand or by mowers. The use of heavy equipment for this purpose shall not be allowed. Removal threshold. Within residential developments, at least 40 percent of the inches of existing significant tree DBH shall be retained on site. Reforestation/restitution requirement. If a development exceeds the removal threshold specified in "Operation of Equipment section 3" above, the developer shall either reforest areas within the site, pay restitution, or some combination thereof. For every one significant tree inch that is removed in excess of the removal threshold, the developer shall replant 1.25 inches (diameter) of new trees or provide the city with $125.00 in restitution. Significant trees removed for water quality treatment ponds, public trails and sidewalks, and arterial and collector streets, or that are considered invasive species, are exempt from the removal threshold calculation. Tree Protection: Protection from disease and pestilence: All clearing in oak stands shall be performed prior to April 15 or after July 15 of each season. Any development involving oak trees on or adjacent to the development area must submit a plan in conjunction with the preliminary plat that identifies what precautionary steps will be taken to protect the trees from oak wilt. Encroachment: If encroachment into a tree preservation area occurs that causes irreparable damage to a tree(s), the tree preservation plan shall be revised to compensate for the loss. Under no circumstance shall the developer be relieved of responsibility for compliance with the provisions of this division, nor shall planned revision activities prevent the city from instituting action for violation of this division. Planting requirements: All trees chosen shall be from the acceptable/preferred list (or have approval of the city) and native and/or adaptable to this region and climate as described in the Ramsey Tree Book. The quantity of the required plantings shall be in accordance with the performance standards established for the respective zoning district.
