OWNER: Renton Regional Fire Authority (RRFA)
18002 108th Ave SE, Renton, WA 98055
PROJECT LOCATION: 1900 Lind Ave SW, Renton, WA 98057 (APN 3340400425)
PROJECT DESCRIPTION: The applicant, Ryan Simonds from Renton Regional Fire Authority (RRFA), is
requesting a Routine Vegetation Management Permit (RVMP) to remove fourteen
(14) trees from the Fire Station 14 parking lot located at 1900 Lind Ave SW (APN
3340400425). The subject property is approximately 261,781 square feet (6.01
acres) and located within the Commercial Office (CO) zone and the Valley
Community Planning Area. According to City of Renton (COR) Maps, the property
is mapped with flood hazards, high seismic hazards, sensitive slopes (>15% & <=
25%), and a wetland.
An Arborist Report, prepared by Terrence J. Flatley, dated September 5, 2025
(Attachment A), was submitted with the application. In the report, the arborist
proposes the removal of fourteen (14) landscaping trees ranging from seven
inches (7”) to fourteen inches (14”) in diameter at breast height (dbh) and
approximately eleven feet (11’) to twenty-eight feet (28’) tall. The proposed trees
for removal are Beech (Fagus), Leyland cypress (Cuprocyparis leylandii), Cherry
(Prunus), and Pear (Pyrus). In the Project Narrative (Attachment B), the applicant
contends that the trees proposed for removal are all dead and therefore should
be removed. All the trees proposed for removal are landscaping trees and the
applicant proposes to replant more suitable trees in the landscaping areas.
CRITITCAL AREA: Sensitive slopes (>15% & <=25%), 100-year flood plain, high seismic hazards,
and East Valley B Wetland.

Routine Vegetation Management Permit
ROUTINE VEGETATION MANAGEMENT REVIEW CRITERIA 4-9-195D.4:
YES 1. The lot shall comply with minimum tree credit requirements pursuant to RMC 4-4-130,
Tree Retention and Land Clearing Regulations.
Staff Comments: In accordance with RMC 4-4-130H, compliance with tree credit
requirements necessitates a minimum of 30 tree credits per net acre. The subject
property, located at 1900 Lind Ave SW (APN 3340400425), is approximately 261,781
square feet (6.01 acres). Based on the property size, 180 tree credits are required to meet
the minimum tree density requirement (30 tree credits per acre × 6.01 acres = 180.3
credits).
According to the Project Narrative (Attachment B), the property has approximately 437
trees measuring between six inches (6”) and twenty-eight inches (28”) in diameter at
breast height (dbh), which means that the minimum tree retention and credits would be
met after the proposed 14 trees are removed. Retention of landscaping trees is required
and is discussed further in Sections 4 and 5.
YES 2. The land clearing and tree removal shall be consistent with restrictions for critical areas,
pursuant to RMC 4-4-130, Tree Retention and Land Clearing Regulations, and RMC 4-3-
050, Critical Areas Regulations.
Staff Comments: According to City of Renton (COR) Maps, Fire Station 14 is mapped
with sensitive slopes (>15% & <=25%), the 100-year fiood plain, high seismic hazards,
and the East Valley B Wetland. The trees proposed for removal include landscape trees
located along SW 19th St (north side of the building), trees located in the parking lot along
Lind Ave SW (west side of the building), and trees located southwest of the building inside
the fence (at the site entrance). No trees are proposed for removal within the wetland
and/or wetland buffer and therefore, the removal would not impact this on-site critical
area. In addition, the proposed tree removal work is not expected to impact the other
critical areas on-site including the mapped regulated slopes (topography), fiooding
hazards, or seismic hazards. Due to these factors, the proposed tree removals do not
require additional critical areas review, and the proposed action is consistent with
restrictions for critical areas.
N/A 3. Removal of a landmark tree shall meet the review criteria for removal of a landmark tree,
pursuant to RMC 4-4-130, Tree Retention and Land Clearing Regulations.
Staff Comments: Per RMC 4-11-200, Deflnitions T, a landmark tree is classifled as such
if it measures with a caliper of twenty-four inches (24") or greater, except for big leaf
maples, black cottonwoods, and red alder trees, which qualify as landmark trees with a
caliper of thirty inches (30") or greater. The trees proposed for mitigation are between
seven inches (7”) and fourteen inches (14”) in diameter at breast height (dbh). Per the
City’s classiflcation these are signiflcant trees; therefore, the review criteria for removal
of landmark trees do not apply.
YES, IF
CONDITIONS
ARE MET
4. Street frontage and parking lot trees and landscaping shall be preserved, unless
otherwise approved by the Administrator.
Staff Comments: The trees proposed for removal are located within landscape areas
along the right-of-way and parking lot. Approval of the requested RVMP would act as
obtaining administrator approval to remove the trees located within the required street
frontage landscape area (ten feet [10'] along all public street frontages), perimeter
landscaping, and interior parking lot landscaping with more than fourteen (14) parking
spaces.

LUA25-000407, RVMP
Permit Date: December 11, 2025 Page 3 of 4
Routine Vegetation Management Permit
It is not reasonably feasible to preserve the existing trees proposed for removal because
the trees are dead and most of them have a high-risk rating for failure. In RMC 4-4-070A,
the purpose and intent of landscaping include improving the aesthetic quality of the built
environment, establish a healthier environment by producing oxygen, along with
improving and softening the appearance of parking areas among other intents. Retaining
the existing dead and dying trees runs counter to the intent behind the landscaping
standards. To support the purpose and intent of landscaping, staff supports replacing the
parking lot trees instead of preserving the existing dead or dying landscaping.
Therefore, to preserve and enhance the landscape character of the City and as a
condition of approval, the dead or dying 14 high-risk trees shall be replaced at a one-to-
one (1:1) ratio, in approximately the same locations as those proposed trees for removal.
As suggested by the arborist in the Replanting Plan (Attachment C), the eight (8) trees
labeled 5, 6, 7, 13, 14, 15, 22, and 23 shall be replaced with Honey Locust trees, while the
six (6) trees labeled 1, 2, 3, 4, 10, and 11 shall be replaced with Tupelo trees. These trees
are recommended due to their suitability for canopy width and the availability of
adequate space for root growth.
YES 5. The land clearing and tree removal shall not remove any landscaping or protected trees
required as part of a land development permit.
Staff Comments: The proposed tree removals are a part of parking lot landscaping and
removal of landscaping is not permissible per code. As discussed above, no live
landscaping would be eliminated, rather the existing dead or 50 percent (50%) dead trees
would be replaced with alternative tree species that are more appropriate for the site
conditions. This would mitigate the issue of preserving the existing dead trees occupying
the landscaping areas and would revitalize the appearance of the landscaping at the
project site.
YES 6. The land clearing and tree removal shall maintain visual screening and buffering between
land uses of differing intensity, consistent with applicable landscaping and setback
provisions.
Staff Comments: The trees proposed for removal are trees used for landscaping along
the right-of-way and near the flrehouse. These trees are not intended to serve the function
as visual screening and buffering between land uses. There is a grove of cottonwood trees
to the south of the parcel to act as a buffer between the Commercial Office (CO) use and
the Light Industrial (IL) use as well as a grove along the east to buffer the wetland. None
of these trees are proposed for removal; therefore, the proposed removal and
replacement would not adversely affect buffering or screening efforts.
YES 7. The land clearing and tree removal shall not create or contribute to a hazardous
condition, such as increased potential for blowdown, pest infestation, disease, or other
problems that may result from selectively removing trees and other vegetation from a lot.
Staff Comments: The provided documentation did not indicate that the removal and
replacement of the existing trees with a more appropriate tree species would create or
contribute to a hazardous condition.
N/A 8. The land clearing and tree removal shall be consistent with the requirements of the
Shoreline Master Program, pursuant to RMC 4-3-090F.1, Vegetation Conservation, and
RMC 4-4-130, Tree Retention and Land Clearing Regulations.

ARBORIST REPORT
Firestation 14
1900 SW Lind Avenue
Renton, Washington 98055
C/O Donald Highley, Facility Technician
INTRODUCTION
Donald Highley, Facility Technician to the Renton Regional Fire Authority, requested an
Arborist Report to apply for City of Renton permits in order to remove several dead trees
on the grounds of Firestation 14.
The firestation is located at 1900 SW Lind Avenue. Geographically it is located in the
Southwest Quarter Section 19, Township 23 North, Range 5 East. The parcel identification
number is 3340400425. The parcel is 261,781 square feet including the firestation and
maintained grounds as well as a wooded cottonwood stand along the east and south
boundaries.
This report applies to the landscape trees found along the north side of the building, trees
in the parking lot, trees along SW Lind Avenue and trees along the south side of the
building inside the fence.
METHOD
Each tree was measured to gather data shown in Table 1 below using a basic level of tree
risk assessment from ground level. Information was gathered on the “ISA Basic Tree Risk
Assessment Form.” Tree locations were pinpointed by number on aerial maps. The maps
relate to Table 1.
Photographs of the dead trees were taken with labels for Trees 1 through 15. Live trees are
shown with numbers 16 through 27 on the maps only; live trees were not photographed
intentionally. An estimate of the quantity of cottonwood trees was made for areas to the
east and south boundaries.
Table 1 is the tree inventory for Trees 1 through 27. It summarizes information on the
assessment forms for each tree. “Basic Tree Risk Assessment Forms were completed for
tree removals (Trees 1 through 7, 10 and 11, 13 through 15, 22 and 23) found at the end of
this report.

CONCLUSION
The information in this report uses a basic level assessment at ground level and considers
tree condition under normal weather conditions typical of the Puget Sound Region.
Periodic inspections should be considered as site conditions may change over time.
Property owners should consider the facts presented in this report and decide what actions
to pursue. Because no one person can predict when trees will fail, there is no warranty or
guarantee that trees in this report will not fail.

PROJECT NARRATIVE: TREE REMOVAL PROJECT
Firesta(on 14
1900 SW Lind Avenue
Renton, WA 98055
The Tree Removal Project is proposed for tree removal at Firesta(on 14, located at 1900 SW
Lind Avenue, further described as being in the Southwest Quarter, Sec(on19, Township 23
North, Range 5 East, Renton, King County Washington. The parcel iden(fica(on number is:
3340400425.
The project is intended to remove 14 trees that have died and found standing. The parcel
currently has 27 trees originally planted in 1996.
Along the east side of the parcel is a stand of black coUonwood trees. Based upon the size of
the stand it is es(mated to contain approximately 437 trees measuring 6 inches to 28 inches in
diameter. They are adjacent to a wetland area on the east and a small wetland por(on on the
south. All trees these coUonwood trees shall be retained.

Planting Plan For Station 14
Renton Regional Fire Authority plan for replacing the dead trees is as follows. Please see
the attached arborist report for the numbering of each tree. It is the Fire Authorities plan to
replant these trees at the earliest time possible where they will be most viable after
planting:
Honey Locust along Linda Ave SW and SW 19th St. where there is more room for roots and
canopy. It was suggested the rest of the trees could be Tupelo and would fit nicely closer to
the building and in parking lot planter strips.
Trees 5,6,7,13,14,15,22,23 would be replaced with Honey Locust
Trees 1,2,3,4,10,11 would be replaced with Tupelo
