Purpose And Intent. The citizens and elected officials of the Village of Twin Oaks realize that trees and vegetation are important elements of the character and ambiance of our Village. The planting, maintenance and preservation of trees and vegetation in the course of land development has also been determined to be a significant issue affecting the public health, welfare and the Village's physical and aesthetic environment. The planting, maintenance and preservation of trees and vegetation will have substantial position effects on storm water management, air quality, quality of water from non-point sources, erosion, flood control, wildlife habitat, noise pollution, energy conservation and property values. It will provide for significant positive aesthetic benefits consistent with the established character of the Village of Twin Oaks. The planting, maintenance and preservation of trees has a significant impact to help moderate the effects of sun, cold and wind and the reduction of pollution and it has a beneficial impact on the general overall well-being of the Village of Twin Oaks. Therefore, the mitigation standards as set out in this Chapter apply to all properties within the boundaries of the Village of Twin Oaks.
Street Tree Species To Be Planted. The Village of Twin Oaks shall maintain an extensive list of recommended trees for planting in public areas. The purpose of this listing will be to maintain diversity in the total tree population. This list shall be available to residents of the Village upon request to aid in the selection of trees for private and public properties. The list of recommended trees shall be updated periodically by the Community Forest Manager or Arborist to reflect new developments or species that will affect the population of the community forest.

Lot Owner's Responsibility. It shall be the duty of the owner of any lot or parcel of ground in the Village to properly cause such trees or tree limbs as are described in Subsection (A) of this Section to be cut down and no tree or tree limb in the Village which has been cut down or which has fallen or been broken down shall be permitted to remain in or upon any sidewalk, street or adjacent property in the Village or so near thereto as to endanger any person thereon and it shall be the duty of the owner of such lot or parcel of ground to cause the same to be promptly removed and it shall be unlawful for any such owner to fail so to do.
Nuisances. Trees or tree limbs on private land that cause obstructions, present insect or disease problem or otherwise present a danger to public health or safety are hereby declared to be a nuisance by the Community Forest Manager, at which time the Village Administrator/Clerk may order such to be pruned, removed or treated.

Order required. The order required herein shall be served by mailing a copy of the order to the last known address of the property owner by certified mail.
Appeal. The property owner has the right to appeal the order to prune, remove or treat by appealing to the Board of Adjustment. The property owner may present any evidence or exhibits to support his/her position that the tree does not need to be pruned or removed or that the cost of the "order" is excessive. If the Board should uphold the order, the property owner has an additional ten (10) days from the Board's decision to complete the required pruning, removal or treatment.
Failure to comply. When a person to whom an order is directed shall fail to comply within the specified time, it shall be lawful for the Village to prune, remove or treat such trees and the exact cost thereof shall be assessed to the owner.

Owners shall trim all vegetation that obstructs the view or passage on any street, sidewalk or bike path. Street tree limbs shall be pruned to fourteen (14) feet or more in height above the road elevation. Dead limbs shall be removed to prevent becoming a hazard to the motoring and pedestrian public.
