The San Luis Obispo Municipal Code is current through Ordinance 1672, and legislation passed through December 3,
2019.
d. The tree removal application materials shall be provided at the same time and in addition to the
development permit application but may reference the development permit application to provide the
information required by this section.
3. As a condition of authorizing tree removal(s), the approving authority may require the development and
implementation of a site-specific tree protection plan that shall be submitted to the city arborist for review
and approval prior to issuance of a tree removal permit.
E. Criteria and Process for Non-Construction Related Tree Removal Application Determinations Related to Tree Health
or Hazard Mitigation or Property Owner Convenience (Refer to Subsection G of This Section for Criteria for Construction
Tree Removal Determinations).
1. The city arborist may authorize a tree removal upon receipt of a removal application pursuant to
subsection D of this section and issue a tree removal permit upon determination of any of the following
circumstances:
a. The tree is an imminent hazard to life or property, and removing it is the only feasible way to
eliminate the hazard (see subsection (I)(2) of this section for director approval of immediate hazard
abatement without a formal application or noticing; removals pursuant to this subsection (E)(1)(a) and
subsection (I)(2) of this section are not appealable);
b. The tree is dead or dying or diseased or damaged beyond reclamation;
c. The tree’s roots are causing severe damage to public or private property, and removing the tree is the
only feasible way to eliminate the damage;
d. The tree is affected by structural defects and/or deficiencies that will limit lifespan;
e. The tree is densely clustered amongst other trees and the requested tree removal promotes good
arboricultural practice;
f. The tree is obstructing vision, access, or mobility of public traffic (see Section 12.24.030, Definitions;
public traffic). Trees requested for removal due to sidewalk infrastructure damage shall have lower
preservation priority when the tree species is known to have invasive root structures that increase the
likelihood that damage will recur if the tree is not approved for removal and where trees requested for
removal are adjacent to sidewalks with a high volume of pedestrian use and/or with large vertical or slope
displacements;
g. The requested tree removal is necessary to alleviate a demonstrated and ongoing maintenance
burden for the property owner exceeding routine tree maintenance.
2. The city arborist will either approve, conditionally approve, or deny the application for tree health or
hazard mitigation based on findings regarding the criteria set forth in subsection (E)(1) of this section. The city
arborist’s determination under this section is appealable to the tree committee pursuant to Section 12.24.180.
The tree committee’s decision also shall be based on findings regarding the criteria set forth in subsection
(E)(1) of this section.
Ch. 12.24 Tree Regulations | San Luis Obispo Municipal Code Page 7 of 17
The San Luis Obispo Municipal Code is current through Ordinance 1672, and legislation passed through December 3,

3. Tree removal requests based on property owner convenience shall be subject to tree committee review in
accordance with the process set forth in subsection (F)(2) of this section, the relevant additional application
requirements set forth in subsection (D)(2) of this section, and the criteria set forth in subsection G of this
section.
4. All other tree removals not specified in this section on any site for which a ministerial development permit
is sought shall be subject to tree committee or other discretionary review related to the discretionary
development permit requested and approval in accordance with the additional application requirements set
forth in subsection (D)(2) of this section, process set forth in subsection F of this section, and criteria set forth
in subsection G of this section.
F. Process for Tree Removals Related to Ministerial or Discretionary Property Development Permits (Including
Construction for Disabled Access).
1. For tree removal requests related to ministerial development permits for the construction of single-family
residences or accessory structures on R-1 or R-2 lots, or for improvements necessary to accommodate access
for a disabled resident of the property (“minor ministerial development permits”), the city arborist shall review
the application, investigate the site, examine the tree or trees in question, review the compensatory planting
plan, and either approve, conditionally approve (with additional compensatory planting requirements or tree
protection measures), or deny the tree removal request(s), based on the criteria set forth in subsection G of
this section, subject to appeal as set forth in Section 12.24.180.
2. For all tree removal requests related to ministerial development permits, other than as specified in
subsection (F)(1) of this section, the tree committee shall review and make a recommendation on the tree
removal application to the community development director based on the criteria in subsections G and J of
this section. The director shall consider the recommendation of the tree committee, as well as the consistency
of the tree removal application with other city development policies and standards applicable to the site, and
shall either approve, conditionally approve or deny the tree removal request, subject to appeal as set forth in
Section 12.24.180.
3. For any tree removal request related to any discretionary development permit application subject to
director action/director hearing/minor and moderate development review/minor use permit/minor
subdivision processes, city arborist shall review the tree removal application and make a recommendation on
the tree removal application to the authorized approving authority based on the criteria set forth in
subsections G and J of this section. The authorized approving authority shall consider the arborist’s
recommendation in addition to the complete development application’s compliance with other applicable city
development policies, codes and standards and shall either approve, conditionally approve or deny the tree
removal as a part of the final discretionary approval, subject to otherwise applicable appeal processes for the
development entitlement.
4. For any tree removal request related to any discretionary development permit application subject to
major development review/tentative tract map/conditional use permit processes, the tree committee shall
review and make a recommendation on the tree removal application to the authorized approving authority
based on the criteria set forth in subsections G and J of this section. The authorized approving authority shall
Ch. 12.24 Tree Regulations | San Luis Obispo Municipal Code Page 8 of 17
The San Luis Obispo Municipal Code is current through Ordinance 1672, and legislation passed through December 3,
2019.
consider the tree committee’s recommendation in addition to the complete development application’s
compliance with other applicable city development policies, codes and standards and shall either approve,
conditionally approve or deny the tree removal as a part of the final discretionary approval, subject to
otherwise applicable appeal processes for the development entitlement.
5. During property development or construction, any tree that is requested to be removed that was not
identified and approved for removal by the authorized approving authority shall return to the authorized
approving authority for approval prior to removal.
6. For tree removal requests related to a ministerial development permit, under subsection (F)(1) or (F)(2) of
this section, where the approving authority for the development permit is the chief building official, the
ministerial development permit application shall not be deemed complete and the chief building official shall
not issue any construction permit unless any necessary tree removal permit has been approved and the time
for appeal has expired.
G. Criteria for Construction Related Tree Removal Recommendation. Recommendations and determinations of the
city arborist and the tree committee regarding any tree removal requests pursuant to subsection F of this section
shall be based upon the criteria in this section. Tree removal recommendations shall be based on the following
criteria:
1. Size of Tree. The scale of the tree shall be considered, as well as the size of the tree’s canopy. Larger, more
visually prominent trees may have a higher preservation priority than smaller, less visually prominent trees;
2. Location of Tree on Private Property. The location of the tree on private property shall be considered. Trees
located in a private rear yard, which are not highly visible from the public right-of-way, may have a lower
preservation priority than trees with a high visual impact to the neighborhood;
3. Species of Tree. Native trees shall have a higher preservation priority than non-native trees;
4. Forestry Best Practice. The number of healthy trees that a given parcel of land will support shall be
considered, and whether removal would enhance the health or survival of remaining trees. Applications that
increase biodiversity of native trees and tree age distribution within a given area are preferred;
5. Public Right-of-Way Obstruction or Displacement. Street trees requested for removal due to obstruction of
vision, access, mobility of public traffic or sidewalk infrastructure repair or replacement shall have a lower
preservation priority when the tree species is known to have invasive root structure or other characteristics
that increase the likelihood that damage is likely to reoccur if not authorized for removal. Trees adjacent to
sidewalks with a high volume of pedestrian use with large vertical or slope displacements may have a lower
preservation priority;
6. Compliance with Subsection J of This Section Regarding Compensatory Plantings. The approving authority may
consider an application proposal to provide compensatory plantings in excess of required minimums in
evaluating this criterion;
Ch. 12.24 Tree Regulations | San Luis Obispo Municipal Code Page 9 of 17
The San Luis Obispo Municipal Code is current through Ordinance 1672, and legislation passed through December 3,
2019.
7. Heritage Trees. A tree which has been designated a heritage tree is prohibited from removal unless the city
arborist authorizes a tree removal upon finding that a tree removal would be related to tree health or hazard
mitigation as outlined in subsection (E)(1) of this section. Heritage trees have the highest preservation priority.
H. Tree Removal by the City.
1. Tree removal requests for any city project must follow the same procedures as any property owner.
2. After receiving approval to remove a tree as part of a capital improvement project, the city shall replace
the tree as soon as feasible during the project at a ratio determined by the public works director.
I. Notification of Tree Removal.
1. The city shall post a sign notifying the public of the date and description of a proposed tree removal. This
sign shall be posted in a prominent location on the property on which the tree removal is requested, visible
from a public right-of-way, for a period not less than five days before either staff consideration of a tree
removal permit or the approval of a ministerial or discretionary development permit.
2. The public works director may waive application and notification requirements for a tree removal and
immediately permit removal when the director determines that a tree’s condition threatens public health,
safety or welfare such that an application and notice are not feasible. The owner of the property on which
such a removal is requested shall produce sufficient proof to the director’s satisfaction that a notice and an
application are not feasible. Removals authorized under this section are not appealable.
J. Compensatory Tree Planting. Tree removals authorized under subsection E or F of this section shall be
compensated by planting a minimum of one new tree for each tree authorized to be removed when planted on
the same property (on site) or two new trees for each tree authorized to be removed when planted on a different
property or within the public right-of-way (off site).
In approving an application for tree removal, the authorized approving authority shall require compensatory
plantings of a size consistent with city engineering standards as set forth in the table below:
Container Size Trunk Diameter (inches)
15-gallon 0.75" to 1.5"
24-inch box 1.5" to 2.5"
36-inch box 2.5" to 3.5"
48-inch box 3.5" to 4.5"
The authorized approving authority may require subsequent compensatory tree plantings in the event that the
original replacement plantings fail to establish and/or may require a bond ensuring that replacement trees shall
be planted and maintained.

K. Expiration of Appeals. Decisions on tree removal by authorized approving authority shall be subject to appeal
according to the appeal provisions of this code, and no removal or related development permit shall be issued
until the appeal period has lapsed.
L. City Street and Sidewalk Maintenance Program.
1. The city has a program whereby staff evaluates and repairs sidewalks and streets on a predetermined
schedule. When the city determines a street tree must be removed to repair the sidewalk, the city will pay all
costs to repair sidewalk, curb, and gutter, remove the tree and plant a new tree.
2. If a property owner wishes to remove a street tree and repair hardscape damage outside of regular city
maintenance and replacement schedules they may do so at their own expense, if the removal is approved in
compliance with subsection E or F of this section. The property owner shall pay for the necessary hardscape
repairs and be required to plant and maintain a new tree as a condition of their approved tree removal, either
in the same location or in another more suitable location. (Ord. 1664 § 3 (Exh. A), 2019)
12.24.100 Control of trees and shrubs for protection of public safety.
A. To prevent hazards to the public, property owners shall maintain all trees, shrubs and other plant growth on
their property or adjacent to their property and within the public right-of-way and shall at all times ensure that no
tree, shrub or other plant for which the property owner bears responsibility is maintained so as to create a
dangerous condition of public property. Hazards shall include, but not be limited to, branches hanging over
sidewalks and shrubbery growing into the right-of-way which interferes with passage or visibility.
B. The city will notify property owners of known hazards by posting abatement notices according to the Streets
and Highways Code, Improvement Act of 1911, Sections 5610 through 5618, or as subsequently amended.
C. Any tree or shrub growing on private property that, in the opinion of the director, endangers public property
shall be removed or trimmed by the property owner within fourteen days after receiving notice from the director.
If the property owner fails to remove or trim the trees or shrubs, the city will conduct the work and assess the
property owner for the cost of the city tree crew or for a contractor to do the work. Any removal and trimming
costs shall become a lien on the property if not paid by the property owner after being billed by the city. These
costs shall be recorded with the county recorder’s office. The assessment may be collected by court action.
D. To the fullest extent permitted by law, the property owner shall bear responsibility for injuries to and shall be
responsible for any liability caused by or resulting from the property owner’s negligent failure to maintain or
repair any tree, shrub or plant growth as required by this chapter.
E. In case of emergency caused by a tree in a hazardous condition, the tree may be removed by order of the
