REVIEWED:
Applicant documents are available online through the City of Renton
Document Center website. See also https://cutt.ly/hn6kpBQ
PROJECT DESCRIPTION:
The applicant, Amazon, is requesting Site Plan Review, Environmental (SEPA) Review, and a Shoreline Exemption for
minor site work and tenant improvements in a 126,600- sq. ft. existing industrial building at 1905 Raymond Ave SW (APN
2423049115). The building was previously occupied by DHL Global Forwarding, a shipping service. The applicant intends
to use the building for its “Amazon Flex” delivery service, in which contract employees pick up packages from the site in
their personal, passenger vehicles and distribute (i.e. deliver) the packages to customers in the Renton area. The proposal
is subject to Environmental (SEPA) Review due to the scope including the addition of new parking stalls in an existing
parking lot with over 20 stalls. In addition, the project site is encumbered by critical areas. The proposed work within the
shoreline, the installation of a bicycle rack, is an exempt action due to the value of the work falling under the fair market
value threshold as outlined in WAC 173-27-040. The applicant has proposed to retain the existing office space for use by
support staff, while updating the warehouse/distributi on space to better meet the needs of the flex delivery service. The
building is located on the north half of a 6.8 acre site near the corner of SW 19th St and Raymond Ave SW. The subject
site is located in the Industrial, Light (IL) zone and Employment Are a Comprehensive Plan Land Use designation.
According to the applicant, all works would be interior except for parking lot re-striping and minor concrete work that
would add a total of 26 new parking stalls as well as new ADA ramps and crosswalks. No trees or vegetation are proposed
for removal as part of the project. According to COR Maps, multiple critical areas are present on the site including a high
seismic hazard, sensitive slopes, a special flood hazard area (FEMA zone AE), and an unclassified wetland . In addition,
the eastern portion of the site is located within Reach C of the Black River/Springbrook Creek Regulated Shoreline Area
NOTICE
and has an environmental designation of Shoreline High Intensity. According to the applicant, the project would result
in a net impervious surface increase of approximately 127 sq. ft.
Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on April 19, 2022. Appeals
to the Examiner are governed by RMC 4-8-110 and more information regarding the appeal process may be obtained
from the Renton City Clerk’s Office, (425) 430 -6510. Due to the ongoing state of emergency enacted by Governor’s
Proclamation 20-05, the City Clerk’s Office is working remotely. For that reason, appeals must be submitted electronically
to the City Clerk at cityclerk@rentonwa.gov or delivered to City Hall 1st floor Lobby Hub only on Tuesdays and/or
Wednesdays. The appeal fee, normally due at the time an appeal is submitted, will be collected at a future date if your
appeal is submitted electronically. Appeals to the Hearing Examiner are governed by RMC 4-8-110 and additional
information regarding the appeal process may be obtained from the City Clerk’s Office, cityclerk@rentonwa.gov.

SUBJECT: Utility and Transportation Comments for SWA2 Amazon
1905 Raymond Ave SW
LUA21-000233
I have reviewed the application for the Amazon distribution facility located at 1905 Raymond Ave SW and have the
following comments:
EXISTING CONDITIONS
WATER: The proposed project is within the City of Renton’s water service area and in the Valley 196 pressure zone.
Below is a summary of the existing water system in the project vicinity:
1. There is an existing looped water main on the site:
• 12-inch and 10-inch looped water main on site that can deliver a maximum capacity of 3,400 gallons per
minute (GPM) – refer to City water project plan no. W-231404
• The static water pressure is approximately 77 psi at ground elevation of 18 feet.
2. There are existing water services to the subject property:
• 2 – 2-inch domestic water meters without backflow prevention assemblies.
• 2-inch landscape irrigation meter with 1.5-inch Double Check Valve Assembly
• 8-inch fire sprinkler stub with 8-inch Detector Double Check Valve Assembly located inside building.
3. There are 4 existing fire hydrants on the site.
SEWER: Sewer service is provided by the City of Renton. There is an existing wastewater lift station with a 4-inch
wastewater main on site (record dwg: S-231404).
STORM DRAINAGE: The northern portion of the site is building and parking lot, the eastern portion of the site is
adjacent Springbrook Creek which is classified as a stream, and on the southern portion of the site are mapped
wetlands. Other critical areas on site are a regulated shoreline with regulated slopes on-site exceeding 25% and a flood
hazard area marking the 100-year flood zone on-site.
The storm water from the parking lot are directed to two private stormwater detention ponds (facility ID No. 146815)
through private stormwater conveyance system consisting of pipes and catch basins that direct surface water to the
stormwater detention ponds (Record Dwg. R-23140C).
STREETS: The project site does not front directly on to a City of Renton public right of way. Rather the project takes
access from the intersection of Raymond Avenue SW and SW 19th Street through an access easement on the adjacent
parcel (PID 2423049020) that separates the project site from the public right of way. The following describes the existing
street sections:
• Raymond Avenue SW (Commercial Access Street) – 60 foot right of way width with an 36 feet paved roadway
(two 18 foot lanes as the roadway approaches the intersection with SW 19th Street) with a concrete curb and
gutter, 6 foot planter, and a 5.5’ sidewalk on each side of the roadway.
ADVISORY NOTES TO APPLICANT
Page 3 of 5 LUA21-000233
• SW 19th Street (Commercial Access Street) – 60 foot right of way width with an 18 feet paved roadway (two 18
foot lanes as the roadway approaches the intersection with SW 19th Street) with a concrete curb and gutter, 6
foot planter, and a 5.5’ sidewalk on each side of the roadway.
WATER COMMENTS:
1. A Reduced Pressure Backflow Assembly (RPBA) will be required behind each of the two (2) existing 2-inch
domestic water meters. The RPBA’s shall be installed in an above ground heated enclosure per City standard
plan no. 350.2. A water permit is required for this work.
SEWER COMMENTS:
1. No Comments
STORM DRAINAGE COMMENTS
1. A drainage report complying with the current Renton Surface Water Design Manual (RSWDM) will be required if
the project results in more than 2,000 square feet of new and/or replaced im pervious surface onsite or offsite.
Based on the City’s flow control map, the site falls within the City’s Peak Rate Flow Control Standard (Matching
Existing Conditions). The site falls within the Black River Basin and Springbrook Creek sub basin. Refer to Figure
1.1.2.A – Flow chart to determine the type of drainage review required in the RSWM.
2. Erosion control measures to meet the City requirements shall be provided.
3. The development is subject to a surface water system development charge (SDC) fees. Fees will be charged based
on the rate at the time of construction permit issuance. The current SDC fee is $0.80 per square foot of new
impervious surface but not less than $2,000. The full fee schedule can be found at:
https://edocs.rentonwa.gov/Documents/DocView.aspx?id=8371984&dbid=0&repo=CityofRenton
TRANSPORTATION/STREET COMMENTS
1. The project does not take direct access off of an existing public right of way therefore no frontage improvements
are required for the project as it relates to Renton Municipal Code (RMC) 4-6-060.
2. A traffic impact analysis (TIA) prepared by NV5 Engineers and Consultants, Inc. dated October 28, 2021 was
submitted for review. The TIA evaluated traffic operations at twenty-three intersections around the site. The
intersections evaluated were:
a. Raymond Avenue SW and SW 19th Street and Site Driveway
b. Lind Avenue SW and SW 19th Street
c. Lind Avenue SW and SW 16th Street
d. Raymond Avenue SW and SW 16th Street
e. Oakesdale Avenue SW and SW Grady Way
f. SW Grady Way and Powell Ave SW
g. SW Grady Way and Lind Avenue SW
h. SW Grady Way and Longacres Drive SW
i. WA-181/Interurban Avenue S and SW Grady Way/Southcenter Boulevard
j. Interurban Avenue S and Fort Dent Way/I-405 Westbound ramps
k. WA-181/West Valley Highway and S 156th Street/I-405 Eastbound off-ramp
l. SW Grady Way and Maple Avenue SW
m. WA-167/Rainier Avenue S and SW Grady Way/S Grady Way
n. WA-167 and I-405 Westbound ramps
o. WA-167 and I-405 Eastbound ramps
p. Lind Avenue SW and SW 27th Street
q. Lind Avenue SW and SW 34th Street
r. Lind Avenue SW and SW 41st Street
s. East Valley Road and SW 41st Street/WA-167 Southbound ramps
t. SW 43rd Street/South 180th Street and WA-167 Northbound ramps
ADVISORY NOTES TO APPLICANT

u. SW 43rd Street/South 180th Street and East Valley Road/East Valley Highway
v. SW 43rd Street/South 180th Street and Lind Avenue SW/88th Ave S
w. Oakesdale Avenue SW and SW 16th Street
The intersections were evaluated using Level of Service (LOS) methodology under existing conditions, existing
plus project conditions, and project opening year conditions. LOS evaluation was done in accordance with the
industry standard Highway Capacity Manual (HCM) Sixth Edition. The turning movements counted were
obtained by StreetLight Data, Inc. in 2019 to capture pre-pandemic traffic patterns. From this data, existing LOS
was determined for each intersection. The report concludes that in the existing condition 16 out of the 23
intersections evaluated operates with an approach or overall LOS below D during at least one peak hour.
As noted in the TIA, the prospective tenant has a unique operation that are different from those included in the
Institute of Transportation Engineers (ITE) trip generation manual, 10th Edition. Trip generation provided by the
tenant is based on their planned employee head count, delivery operation, and line-haul movements. The
development is expected to generate a total of 3,130 daily trips, 341 AM peak hour trips (171 entering, 170
exiting) from 7:00 – 8:00 AM, and 180 PM peak hour trips (102 entering, 78 exiting) from 4:00 – 5:00 PM. This
project trip distribution was projected for the AM, Mid-Day, and PM peak hours. Trips were assigned to the
existing City streets at the study intersections based on an understanding that most of the traffic is destined to
and from I-5 to the west and SR-167 to the east. City staff has reviewed the trip generation and trip assignment
and found it acceptable.
Using the trip assignments, the LOS for the following conditions were established at each intersection:
a. The existing condition without the project;
b. The existing condition with an annual growth rate of 3% for a 2025 Horizon year; and
c. The existing condition with an annual growth rate of 3% for a 2025 Horizon year with the project trip
distribution.
The report concludes that signal warrants at the Lind Avenue SW and SW 19th Street intersection were met
during the AM and PM peak hours for both the existing condition and increased with the project through a 2025
Build Condition.
The report recommends the following mitigation measures be implemented:
a. Intersection of Raymond Avenue SW and SW 19th Street:
i. Widen the westbound approach width of SW 19th Street to a minimum of 20 feet (two 10-foot
lanes).
ii. Provide additional advanced warning signage on the westbound approach of SW 19th Street and
the southbound approach of Raymond Avenue SW.
iii. Trim shrubbery/vegetation in the immediate vicinity of the intersection to improve sight distance.
b. Intersection of Lind Avenue SW and SW 19th Street: Install traffic signal.
c. Intersection of Raymond Avenue SW and SW 16th Street: Install roundabout.
d. Install Adaptive Traffic Control System (ATCS) Split Cycle Offset Optimization Technique (SCOOT) to the
following intersections:
i. Oakesdale Avenue SW and SW Grady Way
ii. Oakesdale Avenue SW and SW 16th Street
iii. Lind Avenue SW and SW Grady Way
iv. Lind Avenue SW and SW 16th Street
In reviewing the NV5’s recommended mitigation measures, City Staff recommend that the above mitigation
measures be provided with the following adjustments:
a. City Staff recommend that the traffic signal recommended at the intersection of Lind Avenue SW and
SW 19th Street be constructed in a way that accommodate the future construction of an additional 11-
foot lane on Lind Avenue SW.
ADVISORY NOTES TO APPLICANT
Page 5 of 5 LUA21-000233
b. City Staff supports the installation of a roundabout at the intersection of Raymond Avenue SW and SW
16th Street or other similar measures to reduce the speed of vehicles traveling on SW 16th Street such as
speed cushions which will also help increase the function of the intersections.
The report also recommends an eastbound right turn lane at the intersection of Oakesdale Avenue SW and SW
Grady Way. In reviewing this proposed mitigation with the City’s Public Works Transportation Operations group,
the additional right turn lane would result in marginal improvements to the intersection but will require
significant impacts on the adjacent Springbrook Creek located on the southwest corner of the intersection in
order to construct the improvements. It is City Staff’s opinion that the intersection will be improved adequately
with the additional of the SCOOT system recommended by NV5 and does not recommend the addition of the
right turn lane at this time.
3. Revisions to any streetlight or ADA ramp will require those facilities to be brought up to the current City of
Renton standards.
4. Paving and trench restoration within the City of Renton right of way shall comply with the City’s standards.
5. Transportation Concurrency is provided under a separate document.
6. A transportation impact fee will be assessed based on the new PM Peak Hour Person Vehicle Trips added by the
project. Based on 180 Net New PM Peak Hour Vehicle Trips proposed, the estimated Impact Fee is anticipated to
be $1,953,746.85 ([180 Net New PM Peak Hour x 1.353 AVO]/ 74.2% Vehicle Mode Share) x 100% New Trips x
83.3% Person Tips per Vehicles x $7,145.85 Current Fee per New PM Peak Hour Person Vehicle Trips). This fee is
due at the time of building permit issuance.
GENERAL COMMENTS
1. The fees listed are for 2021. The fees that are current at the time of the respective permit issuance will be levied.
Please see the City of Renton website for the current fee schedule.
2. Retaining walls that are 4’ or taller from bottom of footing and stormwater detention vaults will require a
separate building permit. Structural calculations and plans prepared by a licensed engineer will be required as
part of the building permit review.
3. All civil plans shall conform to the current City of Renton survey and drafting standards. Current drafting standards
can be found on the City of Renton website.
4. A separate plan submittal will be required for a construction permit for utility work and street improvements. All
