The purpose of this chapter is to recognize, appreciate and provide for voluntary protection of trees that are of landmark importance due to age, size, species, horticultural quality or historic importance.
(Ord. 12-11 §1)
A. 
The city manager or designee shall authorize a city board or committee to implement the provisions of this chapter.
B. 
Heritage trees and significant trees may be of equivalent landmark importance due to age, size, species, horticultural quality or historic importance. The designated review body may approve designation as a significant tree for a tree nominated as a heritage tree if the review body determines the tree is of lesser landmark importance, but still worthy of recognition. Alternatively, a tree owner or responsible party may choose to nominate a tree as a significant tree rather than a heritage tree if they determine the tree is of lesser landmark importance, but still worthy of recognition, or if they desire no regulatory protection of the tree they would like to have recognized.
(Ord. 12-11 §1)
A. 
Any person may nominate a particular tree or group of trees to be designated as a heritage tree due to age, size, species, horticultural quality or historic importance. The nomination shall be submitted by the tree owner or responsible party or accompanied by the tree owner or responsible party's written consent. If the nominated tree is located on city property, the nomination shall be submitted by the city manager or designee or be accompanied by the city manager's or designee's written consent. Upon completion of the nomination process, the remaining portions of this subsection shall apply in the order listed.
B. 
After reviewing the nomination materials, and any supplemental information provided by the city manager or designee, the designated city board or committee may decide by majority vote to:
1. 
Recommend approval of the tree to be designated as a heritage tree upon finding it is of landmark importance due to age, size, species, horticultural quality or historic importance, and forward their recommendation to the City Council.
2. 
Approve the tree to be designated as a significant tree upon finding it is of landmark importance due to age, size, species, horticultural quality or historic importance. Upon receipt of the tree owner's or responsible party's written consent for designation as a significant tree, the tree shall be included in a publicly accessible inventory of trees.
3. 
Deny the tree as a heritage tree and significant tree.
C. 
When the designated city board or committee recommends that council designate a tree as a heritage tree, the city manager or designee shall prepare for the tree owner or responsible party the paperwork necessary to record the heritage tree designation on the owner's or responsible party's deed, noting on such deed that the tree is subject to the provisions of this chapter. If the tree owner or responsible party fails to sign the necessary paperwork, the heritage tree designation shall be void, the matter shall not move forward to council, and the provisions of this chapter shall cease to apply to the tree.
D. 
After reviewing the nomination materials, any supplemental information provided by the city manager or designee, and the designated city board or committee's recommendation, the City Council may decide by majority vote to:
1. 
Approve the tree to be designated as a heritage tree upon finding it is of landmark importance due to age, size, species, horticultural quality or historic importance, at which point the city shall execute the necessary paperwork to record the heritage tree designation on the tree owner's or responsible party's deed, noting on such deed that the tree is subject to the provisions of this chapter. In addition, the tree shall be included in a publicly accessible inventory of trees.
2. 
Approve the tree to be designated as a significant tree upon finding it is of landmark importance due to age, size, species, horticultural quality or historic importance. Upon receipt of the tree owner's or responsible party's written consent for designation as a significant tree, the tree shall be included in a publicly accessible inventory of trees.
3. 
Deny the tree as a heritage tree and significant tree.
