The purpose of this chapter is to
regulate the removal of trees, encourage and assist property owners
in managing large forested properties, and prescribe preventative
protection measures to avoid damage to trees during site development
in order to preserve the wooded character of the City of Lake Oswego
and to protect trees as a natural resource of the City.

Means a person who has met the criteria for certification
from the International Society of Arboriculture and maintains accreditation.
Means the cross-sectional area (in square ft.) of the trunk
of a tree measured 54 in. (4.5 ft.) above mean ground level at the
base of the trunk, calculated from the diameter at that height (DBH);
basal area equals tree diameter squared, times 0.005454. This is the
same as radius divided by 12, squared, times Pi (approximately 3.14159).
For an explanation of how to calculate the tree diameter, see definition
of "Caliper Inch" below.
Where this Code requires a minimum caliper or caliper inch
tree, the caliper inch of the tree proposed to meet the requirement
is determined by:
If the required caliper inch is less
than four in., the circumference of the tree trunk is measured six
in. above the root ball (for nursery stock or other trees not in ground),
or if planted, the ground.
If the required caliper inch is four
in. or more, the circumference of the tree trunk is measured 12 in.
above the root ball (for nursery stock or other trees not in ground),
or if planted, the ground.
|
The circumference (in inches) is
divided by 3.14 to determine the caliper inch of the tree.
|
Means the City Manager or the City Manager’s designee.
Means a tree is lifeless or is in a state of progressive
and irreversible decline. Among the factors that could be considered
to determine if the tree is lifeless include unseasonable lack of
foliage, brittle dry branches, or lack of any growth during the growing
season. Among the factors that could be considered to determine if
the tree is in progressive and irreversible decline include chlorotic
foliage, an overall thinning of the crown, significant branch mortality,
top dieback, premature fall coloration and defoliation, or abnormally
abundant fruit and flower production.
Means the tree trunk diameter measured at 4.5 ft. (54 in.)
above mean ground level at the base of the trunk, except that if a
tree splits into multiple trunks above ground but below 4.5 ft., the
trunk is measured at its most narrow point beneath the split. The
diameter is calculated by dividing the circumference by 3.14.
Means an imaginary vertical line extending downward from
the outermost tips of a tree’s branches to the ground.
Means a certified or licensed (as applicable) arborist, forester,
landscape architect, forest ecologist, or similar natural resource
professional, with expertise in developing silvicultural prescriptions.
Means a lot, parcel, or tract, or a portion thereof, one
acre or larger in area containing not less than one acre of tree canopy
or meeting the applicable stocking level for high/medium/low site
class(es), as applicable, under the Oregon Forest Practices Act (OFPA).
Where stocking level is used (e.g., for a forest management permit)
site class is determined by a qualified forest management professional
at the time of application submittal. A property may have more than
one large forested tract on it, and forest land on contiguous tracts
under the same ownership may be considered together in calculating
the minimum area of one acre.
Means the tree is of a species that can bear an annual crop
of edible fruit that is grown for human consumption. For the purposes
of this chapter, trees that produce fruits comprised of a hard shell
and a seed, commonly referred to as nuts, are excluded (e.g., walnut,
chestnut, oak).
Means a tree species listed on the Invasive Tree Species List on file with the Planning Department.
The Invasive Tree Species List shall include:
Tree species listed by resolution
of the City Council; and
Tree species added by the City Manager
from time to time, upon finding that the tree species has been introduced
to locations outside of its native range, the tree species has spread
and now persists over large areas, and the tree species negatively
impacts natural ecosystems by displacing native species, reducing
biological diversity and interfering with natural succession.
Means the list of trees listed in Appendix 55.02-1, which are suitable mitigation for the removal of a native tree approved by a Type II permit (LOC § 55.02.080; LOC § 55.02.084(4)(a)(ii)).
Means a tree identified as native in the City’s Master Plant List (LOC § 50.11.004 Appendix D).
Means any individual or legal entity.
Means to cut down a tree or remove all or 50% or more of the crown, trunk, or root system of a tree; or to damage a tree so as to cause the tree to decline, die, or to qualify as hazardous (LOC § 55.02.042(4)). "Removal" includes but is not limited to topping, damage inflicted upon a root system by application of toxic substances, operation of equipment and vehicles, storage of materials, change of natural grade due to unapproved excavation or filling, or unapproved alteration of natural physical conditions. "Removal" does not include normal trimming or pruning of trees.
Means a healthy, noninvasive tree over 15 in. DBH that is
considered significant to the neighborhood due to size, species, or
distinctive character, or the only remaining tree on a property.
Means any of the following: a detached home, a townhouse
or rowhouse, a zero lot line dwelling, duplex, or a condominium unit
where the tree cutting permit relates to a tree located in the private
yard of such a unit.
Means a group of trees (of the same species or a mixture)
that forms a visual and biological unit at least 15 ft. in height
with a contiguous crown width of at least 120 ft.
Means the number of trees on a given area, as in the case
of trees per acre required to be retained or planted after removal
under a forest management permit. "Restocking" means trees planted
under a forest management permit for reforestation. Stocking counts
trees of all sizes and ages, including seedlings and young trees.
Means a tree 1.5 in. or larger in diameter at breast height
(DBH) located within the public right-of-way, a pedestrian easement
abutting a right-of-way, or within a street tree easement, or used
to meet the street tree requirements for a prior development permit.
Means a tree of six ft. in height or less whose top was removed
either under a tree removal permit or by an act of nature.
Means the severe cutting back of a tree’s limbs to
stubs three in. or larger in diameter within the tree’s crown
to such a degree so as to remove the natural canopy and disfigure
the tree.
Means any woody plant having a trunk six in. or larger in
diameter at breast height (DBH), except that for purposes of restocking,
"tree" means a woody perennial plant, often but not always with one
dominant trunk, with the capacity to achieve a mature height greater
than 16 ft. If a tree splits into multiple trunks above ground, but
below 4.5 ft., it is considered one tree. If the tree splits into
multiple trunks below ground, each trunk shall be considered one tree.
For the purposes of this chapter, stumps, shrubs, and hedges that
otherwise meet the above description (common examples include rhododendrons,
camellia, English laurel, Portuguese laurel, photinia, arborvitae,
and hazelnuts) shall not be considered a "tree."
Means the total ground area covered by a tree or a stand
of trees, as measured at the outer limit of tree branches or crown,
projected to the ground. This is also referred to as the tree dripline.
Means written authorization from the City for a tree removal
to proceed as described in an application, such authorization having
been given in accordance with this chapter.
Means a person who has met the criteria for qualification
in tree risk assessment from the International Society of Arboriculture
and maintains accreditation.
Means water, sewer, gas, electric, and telecommunications
services, including all infrastructure required for an exchange.

1.
If a major or minor development permit applied for pursuant to LOC §§ 50.07.003.15 or 50.07.003.14, respectively, would require or result in tree removal and/or a tree cutting permit as defined in this chapter, compliance with LOC § 55.02.080 shall be a criterion of approval of such development permit. Tree removals in conjunction with a major or minor development permit shall be considered in conjunction with such permit and shall be subject to the application, notice, hearing and appeal procedures applicable to the proposed major or minor development. The required notice for major or minor developments that would require or result in tree removals shall include a site plan indicating the location of any trees proposed for removal on the subject site. The proposed trees shall also be flagged with yellow flagging tape on site. Such flagging shall be maintained until a final decision on the proposal is rendered. The remaining notice, hearing and appeal procedures in LOC Chapter 55 shall not apply to tree removals considered in conjunction with a major or minor development request. Subsequent tree removals that have not been reviewed through either major or minor development procedures shall be reviewed as provided in this chapter.
2.
Once a final decision has been rendered on the major or minor development permit, trees that have been approved for removal as part of that decision shall be subject to the verification permit process. Applications for verifications shall be made on the application forms as prescribed by the City Manager and be accompanied by an application fee as established by resolution of the City Council. The purpose of the verification process is to ensure that the trees approved for removal are properly identified for removal in the field and that the trees that were not approved for removal are not inadvertently removed. Removal of trees in violation of such land use approval will be considered a violation of this chapter. The criteria contained in LOC § 55.02.080 shall not apply to verification applications for tree cutting permits.
3.
If a tree proposed to be removed has been specifically required to be preserved or protected as a condition of approval of a land use action pursuant to the Lake Oswego Community Development Code, the tree removal application shall be processed as a modification to that land use action and shall be reviewed subject to the criteria of LOC § 55.02.080 by the body responsible for reviewing such land use actions. Such modification procedure shall not be required in cases of an emergency as provided in LOC § 55.02.042(5), or when the tree is dead as provided in LOC § 55.02.080(1) or is a hazard as provided in LOC § 55.02.080(2).

A person who desires to remove a
tree shall first apply for and receive one of the following tree cutting
permits before tree removal occurs:
1.
Type 1 Permit is required for:
a.
A property that is located in a residential
zone and is occupied by a single-family dwelling;
b.
Removal of up to two trees, 15 in.
DBH or less per tree within a calendar year, and removal of any number
of fruit trees regardless of size; and
c.
A tree that is not:
i.
Protected by a condition of approval
of a development permit pursuant to the Lake Oswego Community Development
Code;
ii.
Located within an area or parcel that has been placed on the Historic Landmark Designation List pursuant to LOC § 50.06.009;
iv.
Located within an RC or RP district
or an HBA protection area;
v.
Located within the Willamette River
Greenway (WRG) overlay district;
vi.
Located within the 25-foot Oswego
Lake Special Setback;
vii.
Located on property
owned by the City of Lake Oswego or dedicated to the public, including
parks, open space and public rights-of-way.
|
Type I permits shall be issued without
further review upon application and demonstration by the applicant
that the request qualifies as a Type I permit pursuant to this subsection.
|
2.
Type II Permit:
a.
A Type II permit is required prior
to any tree removal application that does not qualify for issuance
of a Type I permit, dead tree removal permit, hazard tree removal
permit, emergency permit, verification permit, topping permit, invasive
tree species removal permit, or forest management permit as described
in this section.
3.
Dead Tree Removal Permit:
a.
The City shall issue a tree cutting
permit for a dead tree, except as provided by subsection 3.b of this
section, if the applicant demonstrates that a tree is dead or is in
progressive and irreversible decline and warrants removal. The City
may require the applicant to submit a report from an arborist substantiating
that the tree is dead or in progressive and irreversible decline.
b.
In order to provide for wildlife habitat and natural processes, the City Manager may require the retention of a dead tree. Dead trees shall not be removed if located in wetlands, RC protection areas (LOC § 50.05.010.5.b), HBA protection areas, stream corridors, parks or open space areas required to be preserved as a condition of development approval unless the tree presents a potential hazard to persons or property.
4.
Hazard Tree Removal Permit: The City shall
issue a tree cutting permit for a hazard tree if the applicant demonstrates
that a tree is a hazard and warrants removal.
a.
A hazard tree is a tree that is likely
to fall and injure persons or property as evidenced by cracking, splitting,
leaning or physical damage. A hazard tree may also include a tree
that is causing damage to existing public or private services or public
facilities and such facilities or services cannot reasonably be relocated
or repaired. The applicant must demonstrate that the condition or
location of the tree presents a clear public safety hazard or a foreseeable
danger of property damage to an existing structure and such hazard
or danger cannot reasonably be alleviated by treatment or pruning
or moving the service or facility.
b.
The City may require the applicant
to submit a report from a Tree Risk Assessor Qualified Arborist confirming
the hazard potential of the tree, indicated by a high or extreme hazard
rating in the International Society of Arboriculture qualitative tree
risk assessment, along with an analysis of alternative methods to
alleviate the hazard without removal, and submit a completed hazard
evaluation form as provided by the City.
5.
Emergency Permit:
a.
If the condition of a tree presents
an immediate danger of collapse, and represents a clear and present
hazard to persons or property, an emergency tree cutting permit may
be issued. For the purposes of this subsection, "immediate danger
of collapse" means that the tree is already leaning, and there is
a significant likelihood that the tree will topple or otherwise fail
and cause damage before a tree cutting permit could be obtained through
the nonemergency process. "Immediate danger of collapse" does not
include hazardous conditions that can be alleviated by pruning or
treatment.
c.
If a utility service has been interrupted
such that the applicant can demonstrate that repairs cannot be completed
without the removal of a tree, an emergency permit shall be issued.
If the tree is a significant tree or a heritage tree, the applicant
must also demonstrate that the utility cannot practicably be relocated.
d.
Emergency tree cutting permits must
be approved by the City Manager. If an emergency situation arises
at a time when the City Manager is unavailable, and such emergency
creates a significant likelihood that the tree will topple or otherwise
fail before such official becomes available, the owner of the tree
shall photograph the tree showing emergency conditions and then may
proceed with removal of the tree to the extent necessary to avoid
the immediate hazard. Within seven days of such removal, the owner
of the tree shall apply for a retroactive emergency tree cutting permit
and shall submit with the application evidence to demonstrate the
emergency nature of the tree.
e.
The City may require the applicant to hire an arborist to review the evidence to ascertain whether the tree presented an immediate danger of collapse. The person or entity performing the removal shall not be eligible to provide this review. If the evidence shows that the tree did not satisfy the emergency tree removal standards set forth in this chapter, the application shall be denied and the owner of the tree shall be subject to penalties pursuant to LOC § 55.02.130 and the mitigation requirements of LOC § 55.02.084.
6.
Invasive Tree Species Removal Permit: The
City may issue a tree cutting permit for a tree that is on the Invasive Tree Species List upon the applicant’s compliance with the requirements of LOC § 55.02.050(1)(a).
7.
Verification Permit:
a.
If a site has received development approval through a major or minor development process or for a ministerial resource enhancement project pursuant to LOC §§ 50.05.010.5.c.iii(7) or 50.05.010.6.c.ii(1)(f), then a verification permit shall be issued for those trees approved for removal through that process. To obtain a verification permit, an applicant must clearly identify in the field the trees to be removed by tying yellow tagging tape around each tree and submitting a site plan indicating the location of the requested trees. The City Manager may require the building footprint of the development to be staked to allow for accurate verification of the permit application. The City Manager will then verify that the requested trees match the site plan approved through the major or minor development process or resource enhancement project. The City shall require the applicant to mitigate for the removal of each tree pursuant to LOC § 55.02.084. Such mitigation requirements shall be a condition of approval of the original development permit.
b.
Any tree not approved for removal through the original major or minor development review process or resource enhancement project shall not be approved as part of the verification permit process, unless the subject tree is located within an approved building footprint, public/private utility or improvement area, and no feasible alternative exists to preserve the tree. In such cases, the City may allow the tree to be removed without a Type II tree cutting permit process; however, the mitigation requirements of LOC § 55.02.084 shall still apply.
c.
Verification permits shall be issued
upon application and demonstration by the applicant that the request
complies with this section. Verification permits shall not be issued
prior to the issuance of a building permit for the subject property
without prior authorization by the City Manager.
8.
Topping Permit:
a.
A topping permit may be issued only
if the following apply:
i.
A utility, public agency, or other
person who routinely tops trees in furtherance of public safety may
apply for a topping permit pursuant to this section based upon an
arborist or forester report establishing a methodology for topping
in compliance with this subsection.
ii.
Trees under utility wires may be
topped only where other pruning practices are impractical.
b.
The City, in granting approval for
tree removal in an open space or undeveloped area, may allow a tree
to be topped to a designated height in order to maintain a "snag"
for wildlife habitat.
c.
A tree cutting permit obtained for
tree removal shall not authorize topping unless said tree cutting
permit specifically authorizes such action.

The applicant shall have the burden of
proving that the application complies with the criteria for approval
of the applicable class of permit.
3.
Misrepresentation of any fact necessary
for the City’s determination for granting a tree cutting permit
shall invalidate the permit. The City may at any time, including after
a removal has occurred, independently verify facts related to a tree
removal request and, if found to be false or misleading, may invalidate
the permit and process the removal as a violation. Such misrepresentation
may relate to matters including, without limitation, tree size, location,
health or hazard condition, and owner’s authorized signature.

1.
Purpose. The criteria for approval of forest
management permits are intended to sustain forest cover and health,
and assist property owners in managing forested properties, while
minimizing the risk of catastrophic events such as wildfire, drought,
pest and disease infestations, storms (tree blow-down), and landslides.
In addition, large forested tracts can provide thermal comfort and
energy conservation (where stands of trees provide summer shade and
windbreaks); water quality (through reduced storm water runoff and
erosion); air quality; noise reduction (e.g., in areas of dense trees
and shrubs); wildlife and biodiversity; income for property owners;
and aesthetics, which can contribute positively to community identity,
real estate values, commerce, recreation, and individual health and
well-being.
2.
Applicability. An owner of a large forested
tract or the owner’s authorized agent may apply for removal
of one or more trees from the subject tract provided the tract is
not subject to a pending application for minor or major development,
and the subject trees are not:
a.
Noteworthy landscape features included in the Cultural Resources Inventory Field Form for a property that has been placed on the Historic Landmark Designation List pursuant to LOC § 50.06.009, except if the “Statement of Significance” indicates the features are not significant to the landmark;
c.
Located within an RP or RC district,
or HBA protection area;
3.
Minor Forest Management Permit. An owner
of a large forested tract or the owner’s authorized agent may
apply for a minor forest management permit to remove trees under the
following criteria:
a.
Removal of up to six trees or four
square ft. of basal area, whichever is greater, within one calendar
year for every one acre (43,560 sq. ft.) of a large forested tract
(round to the closest whole number of trees).
b.
Removal of any number of trees that meet the criteria in LOC § 55.02.042 for a dead tree removal permit, hazard tree removal permit, emergency permit, topping permit, or invasive tree species removal permit may be combined in one minor forest management permit. The City Manager may require a report from a qualified forest management professional to address the respective criteria.
c.
Soil, felled trees, and debris shall be contained within the subject tract; forest management activities shall not cause erosion or alter the flow of surface waters onto an adjacent property. An erosion control permit approved by the City Manager pursuant to LOC Chapter 52 is required prior to tree removal activities that disturb 500 sq. ft. or more of land surface area, or any land area within 50 ft. of a stream corridor boundary.
d.
If the site was subject to a development permit, the removal of trees shall not be contrary to the development permit pursuant to LOC Chapter 50.
|
Minor forest management permits shall
be issued without further review upon application and demonstration
by the applicant that the request qualifies as a minor forest management
permit pursuant to this subsection.
|
4.
Major Forest Management Permit (Forest Management Plan). An owner of a large forested tract or the owner’s authorized agent may apply for a major forest management permit to remove more trees than would be permitted under a minor forest management permit. An application for a major forest management permit shall be accompanied by a forest management plan prepared by a qualified forest management professional, which shall be reviewed and approved by the City Manager pursuant to the notification requirements in LOC § 55.02.082 and the following criteria:
a.
The forest management plan shall
include a description of the existing conditions and identify and
describe the forest management objectives that it is intended to implement
for each tree stand type proposed for treatment. Forest management
objectives include pest management; disease prevention and treatment;
protection against catastrophic events, such as wildfire and storms
(tree blow-down); removal of individual hazard trees; water quality
protection or improvement; removal of invasive species; and routine
pruning, thinning, and replanting of trees for forest health and diversity;
b.
Forest management shall not include
the felling and removal of all trees from a stand (clearcutting),
except where a stand is predominately comprised of diseased trees,
treatment by other means is not practicable, and the forest management
plan provides for restocking with nonsusceptible species;
c.
Forest management activities will
not have a significant negative impact on erosion, soil stability,
flow of surface waters, protection of adjacent trees, or existing
windbreaks;
d.
Forest management activities will not result in removal of more than 50% of the basal area of trees within a required setback yard under the applicable zoning district (LOC Chapter 50). The reviewing authority may grant an exception to this criterion when alternatives to tree removal have been considered and no reasonable alternative exists but to allow the proposed forest management activities. In making this determination, the reviewing authority shall consider the advice of a qualified forest management professional;
e.
Removal of the tree(s) is not for
the sole purpose of providing or enhancing views. Thinning and pruning
of trees to provide a fuel break next to an existing dwelling is allowed
subject to compliance with the criteria of this section;
f.
Removal of trees shall substantially conform to any development permit issued for the site pursuant to LOC Chapter 50.
g.
The application shall contain a forest

An applicant for a Type II tree cutting
permit shall demonstrate that the following criteria are satisfied.
The City Manager may require an arborist’s report to address
the criteria for a permit.
1.
The tree is proposed for removal because
it has outgrown its landscape area or the removal is part of a landscape
plan, or in order to construct development approved or allowed pursuant
to the Lake Oswego Code or other applicable development regulations.
The City Manager may require the building footprint of the development
to be staked to allow for accurate verification of the permit application;
a.
For the purposes of this section,
a tree that has outgrown its landscape area may include, but is not
limited to, a tree that has grown such that damage to a structure
or facility cannot be avoided by pruning or other maintenance, a tree
that has grown too large within a constrained space such as a deck
or other built feature that was constructed around the tree, or thinning
to improve the health of other trees.
b.
For purposes of this section, a "landscape
plan" shall consist of plantings but may also include walkways, patios
and other landscape features; the plan must include more than removing
the tree for which the Type II permit is requested and planting required
mitigation trees;
2.
Removal of the tree, considering proposed
mitigation measures, will not have a significant negative impact on
erosion, soil stability, flow of surface waters, protection of adjacent
trees, or existing windbreaks;
3.
Removal of the tree will not have a significant
negative impact on the character or aesthetics of the neighborhood.
This standard is met when removal of the tree(s) does not involve:
a.
A significant tree;
b.
Alterations to the distinctive features or continuity of the neighborhood
skyline, as viewed from all public streets and properties within 300
ft. of the property;
c.
A tree that serves as a visual screen between a residential zone
and an abutting nonresidential zone, or between a low density residential
zone and a medium or high density residential zone, or between a medium
and high density residential zone;
d.
A street tree; or
e.
Greater than 50% of a stand of trees.
|
Exceptions: This subsection 3. is not applicable when:
|
|
a.
|
A tree is likely to or will continue to cause damage to a permanent,
viable existing structure, or to infrastructure, such as utilities
or paved landscape features, that cannot be remedied through reasonable
tree maintenance or pruning; or
|
|
b.
|
Alternatives to the tree removal have been considered and no
reasonable alternative exists to allow the property to be used as
permitted in the zone. In making this determination, the City may
consider alternative site plans or placement of structures (development
purpose) or alternate landscaping designs (outgrown landscape area;
landscape plan) that would lessen the impact on trees, so long as
the alternatives continue to comply with other provisions of the Lake
Oswego Code;
|
4.
Removal of the tree is not for the sole
purpose of providing or enhancing views;
5.
Removal of the tree is not contrary to
another section of the Lake Oswego Code; and

1.
An applicant for a Type II tree cutting
permit or a major forest management permit shall:
a.
Complete a public notice form. City
staff shall distribute the notice to the neighborhood association
whose boundaries include the proposed tree removal site;
b.
Complete a certification that the
property will be posted and the trees will be marked pursuant to this
section;
c.
Within 24 hours of applying for a
tree cutting permit, post a public notice sign of a pending tree cutting
permit as provided by the City on the subject property or associated
access easement in a location that is clearly visible and readable
to vehicles traveling on a public street and to pedestrians walking
or biking by the property. The public notice sign shall state that
a tree cutting permit is pending for trees on the property marked
by yellow plastic tagging tape (or other means approved by the City,
in the case of forest management permits), and shall include:
i.
The date of posting and the pending
permit number as assigned by the City Manager, and state that City
staff will consider any comments on the pending permit that are received
within 14 days of the date of posting. For pending forest management
permits, the notice shall include a brief summary of the proposed
tree removal and forest management activities;
iii.
Telephone number, City
website address, and Planning Department location and hours to obtain
information about the application, submit comments, obtain the tentative
decision, and determine the last date to request a hearing.
d.
Mark each tree proposed to be removed
by tying or attaching a yellow plastic tagging tape to the tree at
4.5 ft. above mean ground level at the base of the trunk, on or prior
to the same day that the property is posted; and
i.
Exception: For tree removal under
a forest management permit, trees may be identified with tree marking
paint, flagging, or other methods recommended by a forest management
professional and identified in the permit;
e.
Maintain the tree marking until the
final decision is issued.
2.
After the close of the 14-day comment period:
a.
If the tree cutting permit application
is associated with development that is the subject of a building permit
application, review of the tree cutting permit application shall be
suspended until the associated building permit application is reviewed
and the development is found to be in conformance with the Community
Development Code standards. City staff shall then promptly make a
tentative decision approving the permit, approving the permit with
conditions, or denying the permit. (If the development in the associated
building permit is materially different than the development as described
in the tree cutting permit application, the applicant shall modify
the tree cutting permit application so that the proposed development
is materially consistent with the development in the associated building
permit; the tree cutting permit application shall then be renoticed
for a new comment period.)
b.
If the tree removal permit application
is not associated with development that is the subject of a building
permit, City staff shall promptly make a tentative decision approving
the permit, approving the permit with conditions, or denying the permit.
c.
The tentative decision shall be posted
on a Planning Department internet case file webpage, referencing the
address stated in the posted notice. A notice of tentative decision
shall state the deadline to file a request for hearing.
d.
The notice of tentative decision
shall be given to the applicant, neighborhood association, and persons
that submitted written comments. The notice of tentative decision
shall be provided by email to the person’s/association’s
submitted email address, or if no email address is provided by a person
but a mailing address is provided, then by first class mail.
3.
If no request for a hearing is received within seven days after the tentative decision is issued and notice of tentative decision is given to the applicant, neighborhood association, and to persons that submitted written comments pursuant to LOC § 55.02.085, the tentative decision shall be the final decision.
4.
If a request for hearing is timely filed, City staff shall immediately post a red sign on the subject property in the same manner as the posted notice under subsection 1.c of this section, stating a tentative decision on an application for tree removal was issued, a timely request for hearing was filed, and the location, time and date of the hearing. The applicant shall maintain the posting of this sign and the tree marking, until the date of the hearing.
5.
Failure to install or maintain the required
notice and marking may result in denial or delay in issuance of the
permit or revocation of an approved permit.
6.
The tree cutting permit shall be issued
promptly after the decision approving the tree cutting removal application
is final, except if the tree cutting permit application is associated
with a building permit application, the tree cutting permit shall
be issued concurrently with the building permit.
