The species of trees planted in the parkstrips should comply with the list contained in the Streetscape Plan unless otherwise approved by the Urban Forester. They should also be planted as set forth in the Streetscape Plan and Sandy City's Standard Specifications and Details for Municipal Construction, which states that no trees are to be planted within intersection sight triangles. See detail for exact dimensions of the sight triangle, which can vary depending on location.
(5)
Remove private trees or limbs that have fallen upon a City street, property, or sidewalk.
(6)
Maintain ground covers, except in those parkstrips maintained by the City.

If the hazard tree is not mitigated, abated, removed, or corrected within 28 additional calendar days after the notice is complete, the City may mitigate, abate, correct, or remove the hazard tree at the expense of such person, firm, or corporation or may take further action as determined.
(5)
The City may recover the costs and expenses incurred in mitigating, abating, correcting, or removing the hazard tree, serving notice, and the costs of a lawsuit, if any.
(6)
If the person, firm, or corporation disputes or denies the City's determination that the tree is a hazard tree or refuses to remove or permit removal, the City may bring an action to abate the hazard tree as a public nuisance. If the City is granted a judgment, the City may recover the costs of having the public nuisance abated.
(7)
The City, its agents, or employees, if acting in good faith, incur no liability for causing removal of a hazard tree.
