B. Maintaining trees in accordance with the standards set forth by the American National Standards Institute Standard for Tree Pruning (ANSI A300), as it may be amended from time to time.

C. Removing or remedying trees that are dead, seriously diseased, badly out of balance, or in the process of falling.

D. Trimming vegetation so that it does not obstruct travel on the streetside apron or present a hazard to pedestrians, vehicles, or private property.

E. Keeping the streetside apron free of permanent obstructions, refuse, junk, or any other large objects that would impede pedestrian travel.

F. Ensuring that paved sidewalks are not excessively cracked, lifted, or vertically displaced.

  1. A crack greater than two inches in width is deemed excessive per se.

  2. A vertical displacement or lift greater than one inch is deemed excessive per se.

A property owner shall be responsible for any nonconformance with the responsibilities listed above, regardless of the source or cause of the nonconformance.

Nothing in this chapter shall be interpreted to require a property owner to seek permission from Inyo County before trimming, maintaining, or removing a tree or vegetation in the streetside apron or on private property; provided, however, that this chapter shall not exempt a property owner from seeking the required permits from any county department should the trimming, maintenance, or removal of a tree or vegetation cause the property owner to engage in an ancillary activity, such as encroaching on a county highway, that would otherwise require a permit.

§ 12.20.050. Permitting requirements for the addition of new trees in the streetside…

In deciding whether to grant or deny a permit, the Inyo County road department may consider the following nonexclusive factors:

A. Whether the tree is of a type that can be reasonably anticipated to cause damage to or obstruct the county highway or streetside apron.

B. Whether the tree is of a type that can be reasonably anticipated to cause damage to surrounding properties.

§ 12.20.070. Abatement of tree and vegetation encroachments on county highways.

Should a private property owner fail to maintain the streetside apron or their private property such that vegetation or trees encroach into the county highway or the county highway vertical clearance area, the following abatement procedures shall apply:

A. If an encroachment is determined to exist, the Inyo County road commissioner or his or her designee shall notify the involved property owner and/or legal occupant in writing.

B. The written notification shall contain the following information:

  1. That the property is causing a prohibited encroachment on the county highway and/or county highway vertical clearance area;

  2. That the property owner has sixty days to remedy the encroachment;

  3. That, if the encroachment is not removed within sixty days, the county reserves the right to remove the encroachment and bill the property owner for costs incurred in removing the encroachment.

C. If the encroachment is not removed within sixty days, the Inyo County road commissioner shall send a second letter to the property owner or legal occupant informing him or her of the date on which the county will remove the encroachment.

D. Should the property owner fail to remedy the encroachment by the date stated on the second letter, the Inyo County road commissioner may perform all maintenance necessary to ensure the safety of the county highway and the preservation of the county highway vertical clearance area. All costs including, without limitation, reasonable administrative and attorney fees associated with the removal of the encroachment shall be charged to the property owner. Any fine and/or cost of removing the encroachment may be recorded as a lien against the property.

The Inyo County road commissioner, in their discretion, may shorten the sixty day period for the property owner or legal occupant to remedy the encroachment based on a determination that the encroachment poses an imminent threat to public safety, substantially impedes vehicular traffic, or poses an imminent threat to the structural integrity of the county highway.
A property owner or legal occupant may appeal an order of abatement served pursuant to this section via the procedures and deadlines set out in Inyo County Code Sections 22.12.050(C) and 22.12.050(D) .
All powers granted by this section shall be in addition to the powers given to the Inyo County road department by state and federal law and the Inyo County Code regarding the abatement of encroachments on county highways. Nothing in this section shall be interpreted to limit any power granted to the Inyo County road department by state or federal law regarding the abatement of encroachments on county highways.
