[Ord. No. 23-04, 3-1-2023]
A. Purpose
And Intent. The citizens and elected officials of the City of Twin
Oaks realize that trees and vegetation are important elements of the
character and ambiance of our City. The planting, maintenance and
preservation of trees and vegetation during land development has also
been determined to be a significant issue affecting the public health,
welfare and the City'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 City 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 City of Twin Oaks. Therefore, the mitigation standards
as set out in this Chapter apply to all properties within the boundaries
of the City of Twin Oaks.
B. Street
Tree Species To Be Planted. The City 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
City 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.

ground in the City to maintain or allow any private tree or tree limb
to stand upon such lot or parcel of ground, or street tree or limb

of the property owner by certified or registered mail.
3. Appeal. The property owner has the right to appeal the order to prune, remove or treat by appealing as provided in Section
215.060. 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.

4. 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 City to prune, remove or treat such trees and the cost thereof shall be assessed to the property owner as set forth in Section

The City emergency action shall not relieve the property owner from their responsibilities under Subsection
(B) above, Section
215.120, or elsewhere in the Code for the remaining clean-up and removal of the tree, limbs, and debris on the right-of-way and private property.
2. When an emergency has been declared by the Mayor, County or Governor,
City property owners shall be allowed to collect and place trimmed
greenery upon public rights-of-way adjacent to their property. Such
privilege shall extend for a period of two (2) weeks following the
declaration of an emergency and the City shall, at its expense, provide
for the expedient removal of such materials during that time.
3. To address the need for emergency services in clearing streets and
rights-of-way, the Board of Aldermen may maintain a contractual relationship
with one (1) or more maintenance services dedicated to respond within
twelve (12) hours following notice by the City Clerk or Mayor of an
emergency.
