SEPA STATUS:
A SEPA Determination of Non-Significance (DNS) was issued on January 30, 2020 with a
comment period ending February 14, 2020. As of the date of this Staff Report. No comments
have been submitted in response to the required public notice. If any comments are received
prior to the public hearing they will be submitted as an additional exhibit.
FINDINGS OF FACT:
1.Howard Jeng, Project Manager, of Nelson Worldwide on behalf of Phil Wood of
Dermody Properties, (Applicant) submitted an application for a Conditional Use Permit
(CUP) on October 18, 2019. The CUP application is for construction of two speculative
warehouses in the M-2, Heavy Industrial zoning district. Future tenant or tenants are not
identified.
2.The site is located at 901 C St. SW . The main part of the site is located approximately
630 feet west of C St. SW except for a pipe stem portion of the lot that extends
diagonally to C St SW. The site is flat, approximately 11.72 acres in size and roughly
square in shape with a missing SE corner
3.The site is currently vacant except for a wetland area and associated buffer and a
separate temporary storm pond near the northwest corner. The site has been previously
filled and graded as authorized by City permit.
4.While the Site is referred to as “901 C St SW”, the Site does not border the north-south
aligned C St. SW. Instead, it has two access points to public streets. The southeast
corner of the site has a diagonal pipe stem portion of the lot, leading to C St. SW. Also,
the northeast corner of the site borders the cul-de-sac of the east-west aligned 8th St.
SW , extending west from C St. SW.
5.The area surrounding the site is summarized in the following table:

6.The City’s land use regulations and zoning development standards are contained in
Chapter 18.23 ACC (Commercial and Industrial Zones). Per ACC Table 18.23.030,
“warehousing and distribution” uses within the M-2 zone require issuance of a CUP.
There is not a specific definition within the City’s code for “warehousing and distribution”.
The proposed development configuration consists of a 157,400 sq. ft. building in the
north half of the site (Building A) and a 172,500 sq. ft. building in the south half of the
site (Building B) with a central truck court, in between. The facing walls on each side of
the central truck court contain a row of dock height doors. There are a total of 63 dock
doors. By the relative building sizes compared to the number of loading docks, the
project does not meet the definition of “motor freight terminal” (ACC 18.04.635) which is
characterized by “. . .more than one dock per 5,000 square feet of warehouse, storage,
or related use and used for either (A) the loading, unloading, dispensing, receiving,
interchanging, gathering, or otherwise physically handling freight for shipment. . .” A
“motor freight terminal “is not a permitted use in the M-2 zone.
7.ACC 18.57.020(C)(1) includes additional development standards for warehousing and
distribution uses as follows:
“a. Motor freight transportation is permitted but only as an incidental use to the principal
use of the property.
b.Loading and unloading docks shall not be visible from the street. If this requirement
cannot be met, an additional 10-foot width of landscaping along the abutting street,
meeting the provisions of ACC 18.50.040(C) (Landscape Design and Planting
Requirements), is required.
c.All odors, noise, vibrations, heat, glare, or other emissions shall be controlled within
the confines of a building unless specifically permitted elsewhere by this title.
d.No on-site hazardous substance processing and handling, or hazardous waste
treatment and storage facilities, shall be permitted, unless clearly incidental and
secondary to a permitted use. On-site hazardous waste treatment and storage facilities
shall be subject to the state siting criteria (Chapter 70.105 RCW).”
8.Per ACC 18.02.030(A), the intent of Title 18 ACC ‘Zoning’, is to:
“…implement the City’s Comprehensive Plan. This title will be used to further the growth
and development of the City consistent with the adopted Comprehensive Plan and its
3 of 111
implementing elements. This title will also further the purpose of promoting the health,
safety, morals, convenience, comfort, prosperity, and general welfare of the City’s
population and to prevent and abate public nuisances.”
9. In accordance with ACC 18.64.010 the intent of the Conditional Use (land use) Permit
application, is:
“A. It is the intent of this chapter to provide a process to allow for uses that are not
permitted outright within a zone. Such uses typically require a special degree of control
to make sure that they are consistent with the intent of the zone and compatible with
other existing and permitted uses within the zone. Only those uses listed as requiring
either an administrative or conditional use permit within a particular zone qualify for this
process. The planning director or designee may determine that other similar uses which
are not listed may also qualify for this process. This process shall not replace the
variance procedure in Chapter 18.70 ACC or be used to permit uses that are prohibited
within the zone.”
“C. Uses subject to conditional use approval are those uses that typically have a greater
intensity and/or potential for impacts to surrounding properties, and/or special
characteristics that may not generally be appropriate as a use permitted outright within a
zone, but may be permitted subject to review by the hearing examiner to establish
conditions to protect public health, safety and welfare, and to assure compatibility with
other uses in the zone.”
10. Per ACC 18.23.020(I) the stated intent of the M-2 zone is to:
“…accommodate a broad range of manufacturing and industrial uses. Permitted activity
may vary from medium to higher intensity uses that involve the manufacture, fabrication,
assembly, or processing of raw and/or finished materials. Heavy industrial uses should
not be located near residential development. While other uses may be sited within this
zone, permits for such uses should not be issued if such uses will discourage use of
adjacent sites for heavy industry, interrupt the continuity of industrial sites, or produce
traffic in conflict with the industrial uses”
11. The City’s Comprehensive Plan describes the “Heavy Industrial” land use designation
as:
“This designation allows the full range of industrial uses, as well as certain heavy
commercial uses that serve the needs of workers in light industries are also appropriate.”
12. A Notice of Application (NOA) and Notice of Public Hearing (NOH) was issued on
January 30, 2020. No written comments were received on the NOA and NOH as of the
date of this Staff Report.
13. A SEPA Determination of Non-Significance (DNS) and revised NOH was issued on
January 30, 2020. No written comments were received as of the date of this Staff
Report.

14. Per ACC 18.64.020(B) the City of Auburn Hearing Examiner is authorized to conduct a
public hearing and render a final decision for the requested CUP. The Hearing
Examiner’s decision is appealable to King Co. Superior Court.
15. Per ACC 18.64.030(C) a site plan that includes the details set forth in ACC 18.64.035(A)
is required and shall be made a part of the final decision per ACC 18.64.035(B). This site
plan is included as Exhibit 3.
16. The Applicant has provided a narrative of the project and how it conforms to the CUP
approval criteria as Exhibit 4.
CONCLUSIONS:
ACC 18.64.040 contains the criteria for approval of a Conditional Use Permit. The following is a
staff analysis of this Conditional Use Permit application’s compliance with each criterion. The
criteria are listed below in italics, followed by a staff analysis.
A. The use will not have a substantively greater adverse effect on the health, safety, or
comfort of persons living or working in the area and will not be substantively more
injurious, economically or otherwise, to property or improvements in the surrounding
area than would any use generally permitted in the district. Among matters to be
considered are traffic flow and control, access to and circulation within the property, off-
street parking and loading, refuse and service area, utilities, screening and buffering,
signs, yards and other open spaces, height, bulk, and location of structures, location of
proposed open space uses, hours and manner of operation, and noise, lights, dust,
odor, fumes and vibration;
Staff Analysis: ’C’ St. SW is designated a principal arterial and also a local truck
route within the City’s Comprehensive Transportation Plan. Access to the site will
be provided by driveways on ‘C’ St. SW and 8th St. SW (connects directly to ‘C’
St. SE) to meet International Fire Code (IFC) requirements for access. The ‘C’ St
SW driveway will be restricted to right-in, right-out while the 8th St SW driveway
will be full access.
Trip generation and Levels of Service (LOS) is included in the Traffic Impact
Analysis (TIA) (Exhibit 7) and indicates that off-site intersections included in the
study (as coordinated with the City’s Senior Traffic Engineer) will continue to
operate at an LOS C or better. No additional traffic mitigation measures are
necessitated.
Refuse and service areas will be located internal to the site and adequately
screened with fencing and vegetation, consistent with ACC 18.50.040(5)(a).
Utility facility locations (e.g. PSE) are not known at this time, however, will be
coordinated with the site landscaping to ensure they are adequately screened, as
conditioned below. A minimum of 10% of the site must be in landscaping,
consistent with Zoning Code Standards of Chapter 18.50 ACC.
5 of 111
The location of this facility and enclosed nature of the facility does not currently
lend itself to limiting the hours and manners of operation as it is not located near
any noise-sensitive uses, such as residential. The closest noise sensitive use is a
hotel located approximately 315 feet from the northwest corner of the Site.
According to the TIA (Exhibit #7) the proposed project is estimated to generate
567 weekday daily trips, with 65 trips occurring during the weekday AM peak
hour (50 entering, 15 exiting), and 67 trips occurring during the weekday PM
peak hour (18 entering, 49 exiting) while this is based on a speculative tenant,
the exact numbers are not known at this time, there could be and potential
impacts to roadways with the increase of truck traffic during events at the Outlet
Collection (shopping mall) such as during the holidays, sports tournaments (at
Fieldhouse USA (indoor sports field complex), currently under construction in the
former Sam’s Club tenant space at the mall), and other events (such as
carnivals). Such impacts would be temporary. Payment of the City of Auburn
transportation impact fee will mitigate permanent project-related transportation
impacts of the proposed 330,000 sq. ft. warehouse.
All industrial facilities are subject to ACC 18.31.180, ‘Performance Standards’; as
such, the proposed use would meet the limits for noise, odors, etc. listed in this
Code section.
The Applicant provided the following response for this criterion:
“The use will not have substantively greater adverse effect on the health, safety
or comfort of persons living or working in the area. The use for this site will
maintain the same use. The site is isolated and there is no direct street frontage
except for the ingress/egress points. The site is bounded by railroad track and
the Interurban Trail on the west, by an Industrial service center on the east, by an
industrial warehouse facility to the north, and by a vacant industrial site to the
south. Since the site is undeveloped, this development will bring jobs to this area
and better the economy.”
B. The proposal is in accordance with the goals, policies, and objectives of the
comprehensive plan;
Staff Analysis: The site has a Comprehensive Plan (Comp Plan) Land Use Designation
of “Heavy Industrial” which includes the following policies (from Volume 1, Land Use
Element):
“LU-85 – While this zone should be reserved primarily for the heavier forms of
industrial activities, a wide range of industrial activities may be permitted. These
heavier forms of industrial activities may include outdoor or semi-enclosed
manufacturing, processing, or assembling activities, significant outdoor storage,
and uses involving substantial storage or processing of hazardous materials.
Heavy commercial uses that serve the needs of workers in heavy industries are
also appropriate.”
6 of 111
This policy expresses a desire on the part of the City to reserve appropriate areas for
heavier industrial uses that are more difficult to site due to compatibility. However, the
policy also says a wide range of uses may be permitted. Based on this policy,
“warehousing” could be considered within the realm of “…a wide range of industrial
activities…” and thus is not contrary to this policy. The exact user at this time is
unknown, however, a warehousing/distribution use is anticipated and future tenants
must meet City use regulations
“LU-86 – Parking lots must be located and designed in a manner that softens
their appearance from adjacent public roads. This is accomplished through
landscaping, pedestrian spaces, and the location of buildings on the property.
Where practicable, low-impact development techniques and landscaping should
be used to promote on site stormwater infiltration and shading of hard surfaces.
Minimum and maximum parking ratios must be established for each type of
permitted use.”
Parking areas are shown to be on all four sides of the buildings with the semi-truck
parking located along the west side of Building A and the southeastern side of the
property (See Exhibit 3). Landscaping is required (ACC Table 18.50.040(A)) and
proposed on perimeter areas of the property and between the on-site parking stalls. Per
ACC 18.57.020(C)(1)(b) any dock doors shall either not be visible from the street, or an
additional 10 ft. of landscaping abutting the street is required. A perspective view
drawing will be required along with future submittals to ensure this requirement is met,
as conditioned below.
“LU-88 – Where a heavy industrial use is located adjacent to a property with a
less intense zoning designation, the heavy industrial use bears the burden of
incorporating techniques that mitigate the visual, noise, dust, and odor impacts.”
The property to the east (Marmon Keystone, a logistics facility) is zoned as C-3, Heavy
Commercial, a less intense zoning district, however, there are not any identified impacts
to this adjacent site from the proposed warehouse.
Volume 5, the Transportation Element, of the Comprehensive Plan lists ‘C’ St. SW as
part of the truck route. ‘C’ St. SW is a direct connection to SR 18 and connects to SR
167 (via 15th Ave SW ). ‘C’ St. SW is also designated as a “Principal Arterial” per Volume
5. Volume 5 also contains the Policies for freight movement within the City. In general,
the policies listed are to ensure the Objective of facilitating freight movement through the
City while limiting adverse impacts to traffic. The following Policies are applicable to the
requested CUP:
“Freight-01 – The movement of freight and goods is recognized as an important
component of Auburn’s transportation system.”
“Freight-02 – The movement of freight and goods which serve largely national,
state, or regional needs should take place in such a way so that the impacts on
the local transportation system are minimized. These movements should take
7 of 111
place primarily on state highways, Interstates, or on grade-separated rail
corridors in order to minimize the local impacts.”
Having the potential warehouse located on a Principal Arterial designated road which is
also part of the City’s truck route assists in limiting impacts to lesser classifications of
public streets. ‘C’ St. SW provides direct access to SR 167 (via 15th St SW). An exact
user is not known at this time, hence, the destination of freight is also not known but can
be anticipated to likely use the state highways. Truck traffic within the City is subject to
ACC 9.90.020 ‘Truck route designation and restrictions’ which is appropriate for trips
with origins and destinations outside the city and subject to vehicle weight restrictions.
‘C’ St. SW currently contains a mixture of vehicle types and trip purposes. The arterial
street is characterized by a mixture of employee traffic to the Boeing aircraft
manufacturing plant and other industrial uses developed on its grounds. The street also
contains platoons of schools buses with the nearby school bus facility arriving and
departing to coincide with school hours. Added to this traffic stream is retail consumers
visiting the nearby retail shopping center and future indoor sports fields venue. This
consumer traffic can include a proportion of out-of-town travelers.
Volume 6, the Economic Development Element, includes information relating to the
State’s adoption in 2008 of the “streamlined sales tax” (SST) which provides sales tax
revenue to jurisdictions that have an abundance of warehousing and distribution uses to
offset the change to a destination-based sales tax system. The SST was initially not
included to be extended in the State’s budget after this year, however, has been
extended until 2021. The future fate of this funding source is unknown but has been
subject to repeated threat of expiration. Volume 6 contains the following policies relating
to warehousing:
“ED-15 – Warehouse and distribution land uses are not preferred long-term
economic development and land use priorities for industrially zoned areas of the
City, due to: the loss of sales tax revenue associated with the State’s
implementation of streamlined sales tax legislation in 2008; no substantive
contribution to an increase in per capita income for Auburn residents; no
reduction in the tax burden of Auburn residents; low employment densities, lower
property values; and land use inefficiencies.”
“ED-16 – Increasing the utilization of land for manufacturing and industrial land
uses should be the City’s preferred economic development and land use priority
for industrially zoned areas of the City that are currently dominated by warehouse
and distribution land uses. The City should promote and create incentives for
new manufacturing and light industrial uses, and for the gradual conversion of
existing warehouse and distribution land uses to manufacturing and sales tax
generating land uses.”
These policies indicate that for economic purposes, warehousing and distribution are
more of an economic burden on the City than a preferred land use.
8 of 111
Limited information was provided by the Applicant in regards to potential economic
impacts on the City. The information that was provided was vague and does not appear
to address the concerns raised by these Economic Development policies. The Applicant
provided the following response for this criterion:
“The proposed project is in accordance with the goals, policies and objectives of
the comprehensive plan. The new buildings will sit away from the streets and the
truck court will face each other to minimize visibility from the streets. Although
some trailer storage will be located onsite, it will be located further away from the
main road and will be screen by adjacent property’s building from the right of
way. This new building will attract new and economic forward-thinking tenants
that will diversify the economy, which in terms will have job growth. The new
building will revitalize the undeveloped site by creating modern industrial
buildings that consist of concrete tilt-up walls with reveals to create interesting
lines and storefront office nodes that will create an inviting look at the building
corners.”
Staff finds that the project is both consistent with, and not consistent with, this criterion.
C. The proposal complies with all requirements of this title;
Staff Analysis: The project, as proposed, will meet development standards relating to
setbacks, height, landscaping, and parking consistent with the requirements for a
warehouse within the M-2 zone.
The Applicant provided the following response for this criterion:
“The proposed project complies with all requirements of this title for the
conditional use permit.”
If this request for a CUP is granted, the project will require subsequent applications to
the City; through review and approval of these applications, the City can ensure
consistency with requirements of Title 18 ACC ‘Zoning’. One of the applications will be a
boundary line elimination to combine parcels and avoid property lines through buildings.
If this request for a CUP is granted, the project will be consistent with Title 18 ACC
‘Zoning’ and thus this criterion.
D. The proposal can be constructed and maintained so as to be harmonious and
appropriate in design, character, and appearance with the existing or intended character
of the general vicinity;
Staff Analysis: The proposed site / landscaping plans and building elevations are
included as Exhibit 3. As proposed, the project appears to not be physically out of
character with other uses and properties in the general vicinity. As noted in the table
above under ‘Findings of Fact’ No. 4, the surroundings have a wide variety of uses from
warehouse and logistics related uses to the City’s Maintenance & Operations facility.
9 of 111
Other uses in the vicinity have an even wider range from baseball fields and the Outlet
Collection shopping center to warehouses and wholesalers.
The intent of the M-2 zone is included as ‘Findings of Fact’ No. 9, above. In general the
proposed warehouse use appears to meet the intent of the M-2 zone as it would be
included within the term “industrial uses” and would not interrupt other nearby industrial
uses or the traffic associated with industrial uses as the site is located on a City-
identified truck route.
The Applicant provided the following response for this criterion:
“The proposed project can be constructed and maintained to be harmonious and
appropriate in design, character, and appearance with the general vicinity. The design is
parallel to similar newer industrial building around the vicinity and will harmonize the
industrial area.”
Staff finds the request meets this criterion.
E. The proposal will be supported by adequate public facilities and services and will not
adversely affect the public infrastructure;
Staff Analysis: Adequate public facilities are available or will be made available for the
project including water, sewer, storm, and other utilities. Also, and as discussed above,
the site is located on a truck route and therefore should not adversely affect public roads
or traffic circulation.
The Applicant provided the following response for this criterion:
“The proposed project will be supported by adequate public facilities and services and
will not adversely affect the public infrastructure. The existing accessible public sidewalk
on 8th Street SW will lead to the existing public right away on C Street SW, which will
have access to public transit at the corner of 8th Street SW and C Street SW.”
Staff finds the request meets this criterion.
F. The proposal will not cause or create a public nuisance;
Staff Analysis: No impacts relating to air and water pollution, noise, vibration, glare or
odor are anticipated and the future use(s) will be required to comply with all applicable
City codes, including ACC 18.31.180 ‘Performance Standards’ and Chapter 8.12 ACC
‘Public Nuisances’.
The Applicant provided the following response for this criterion:
“The proposed project has harmonious design and appearance similar to the adjacent
buildings and will not cause or create a public nuisance.”
Staff finds the request meets this criterion.
10 of 111
G. The proposal’s impacts can be appropriately mitigated through the application of
conditions of approval, as applicable.
Staff Analysis: Other than minor landscaping conditions to ensure the site is properly
vegetated and screened, no other conditions are proposed. Conditions to satisfy the
economic impacts to the City are not likely defensibly quantifiable. The Applicant has not
provided any proposal to offset the economic impacts.
The Applicant provided the following response for this criterion:
“If the review of proposed project is found impactful in any way, it is understood that it
can be appropriately mitigated through the application’s condition of approval.”
CONDITIONS OF APPROVAL:
1. The site plan that was formally submitted with the Conditional Use Permit Application is
hereby incorporated into the decision. Any modifications to the site plan shall meet the
following requirements of Chapter 18.64 ACC
Minor Adjustments. Minor adjustments to the site plan may be made and
approved by the planning director or designee. Minor adjustments are those
which may affect the precise dimensions or siting of buildings, but which do not
affect the basic character or arrangement of buildings approved, nor the
development coverage of the development or the open space requirements.
Such dimensional adjustments shall not vary more than 10 percent from the
original.
Major Adjustments. Major adjustments are those, when determined by the
planning director or designee that substantially change the basic design,
coverage, open space or other requirements of the permit. When the planning
director or designee determines a change constitutes a major adjustment, no
building or other permit shall be issued for the use without prior review and
approval such adjustment.
The submittal requirements, and review and approval process for a major
adjustment to the site plan of an approved administrative or conditional use
permit shall be substantially the same as that required for the original
administrative or conditional use permit. An application for major adjustment
meeting the information requirements of ACC 18.64.030 shall be submitted. At
the discretion of the planning director or designee, the applicant may be able to
resubmit or incorporate by reference some portions of the original administrative
or conditional use permit submittal as part of the application for major
adjustment; however, the application for major adjustment shall be subject to the
same submittal, processing, and findings of fact requirements of this chapter for
administrative or conditional use permits, as applicable.
2. All above ground utility facilities shall be visually screened with landscaping that provides
year-round screening from the public way, including the Interurban Trail. The
11 of 111
landscaping plans shall propose an approach that can be implemented where above
ground utility features cannot be predicted in advance.
3. A submittal such as a perspective-view drawing shall be submitted showing the view
from the right-of-way and Interurban Trail to the location of the dock doors on the
buildings. This drawing will be used to ensure the project meets ACC
18.57.020(C)(1)(b).

Application No. PRE19-0040
Conditional Use Permit Written Statement and Finding of Fact:
The site is approximately 815,443 sf (18.72 acres to be confirmed by survey). The site is currently un-
developed.
Dermody Properties plans to redevelop the site by constructing two buildings. Building A (approx. size 157,400
sf), and Building B (approx. size 172,500 sf) with associated loading/truck yard, parking, landscaping, and
storm water detention similar to the attached site plan.
Project Description:
The existing site has two ingress/egress points. One is in the northeast corner of the site off of 8th Street SW,
the other is located in the southeast corner of the site off of C Street SW. The site is isolated and there is no
direct street frontage except for the ingress/egress points. The site is bounded by railroad tracks and the
Interurban Trail on the west, by a Industrial service center on the east, by an industrial warehouse facility to
the north, and by a vacant industrial site to the south.
The proposed buildings are approximately 157,400 sf, and 172,500 sf, with a rectangular footprint oriented in
the east/west direction with a shared truck court between the two. The buildings will be one story, Type III-B
construction, fully sprinklered. While the tenant(s) are not identified at this time, industry norms are generally
93% warehouse and 7% associated office space. The building height will be based upon tenant needs,
approximately 38’ to 40’, at most 45’ per the M-2 zoning height allowed. Interior racking and mezzanines will
be provided to meet tenant requirements.
The south side of Building A has a truck court with approximately 25 truck loading bays facing south. The north
side of Building B has a truck yard with approximately 35 loading bays facing north. Parking is located around
the remaining sides of the building. Storm water detention and management is provided at the northwest
corner of the site. We are showing approximately 3.3% of the site area to be confirmed. There is an existing
wetland to the west of building A. Any additional detention requirements would be handled in an underground
vault.
Finding of Fact:
A. The use will not have substantively greater adverse effect on the health, safety or comfort of persons
living or working in the area. The use for this site will maintain the same use. The site is isolated and
there is no direct street frontage except for the ingress/egress points. The site is bounded by railroad
tracks and the Interurban Trail on the west, by an Industrial service center on the east, by an industrial
warehouse facility to the north, and by a vacant industrial site to the south. Since the site is
undeveloped, this development will bring jobs to this area and better the economy.
B. The proposed project is in accordance with the goals, policies and objectives of the comprehensive
plan. The new buildings will sit away from the streets and the truck court will face each other to
minimize visibility from the streets. Although some trailer storage will be located onsite, it will be
located further away from the main road and will be screen by adjacent property’s building from the

right of way. This new building will attract new and economic forward-thinking tenants that will
diversify the economy, which in terms will have job growth. The new building will revitalize the
undeveloped site by creating modern industrial buildings that consist of concrete tilt-up walls with
reveals to create interesting lines and storefront office nodes that will create an inviting look at the
building corners.
C. The proposed project complies with all requirements of this title for the conditional use permit.
D. The proposed project can be constructed and maintained to be harmonious and appropriate in design,
character, and appearance with the general vicinity. The design is parallel to similar newer industrial
building around the vicinity and will harmonize the industrial area.
E. The proposed project will be supported by adequate public facilities and services and will not
adversely affect the public infrastructure. The existing accessible public sidewalk on 8th Street SW will
lead to the existing public right away on C Street SW, which will have access to public transit at the
corner of 8th Street SW and C Street SW.
F. The proposed project has harmonious design and appearance similar to the adjacent buildings and
will not cause or create a public nuisance.
G. If the review of proposed project is found impactful in any way, it is understood that it can be
appropriately mitigated through the application’s condition of approval.

FINDINGS/CONCLUSIONS
This traffic impact analysis (TIA) has been prepared for the proposed LogistiCenter at Auburn
warehouse project located south of 8th Street SW between the C Street SW and the Union Pacific
railroad tracks in Auburn, WA.
Project Proposal. Current plans for the project include the development of approximately 330,000
square feet (SF) of warehouse building area. The existing site is currently vacant. Access to the site
would be provided by a full access driveway on 8th Street SW and a right-in/right-out driveway on
C Street SW. Full buildout of the project is estimated to occur in 2021.
Trip Generation. The proposed warehouse project is estimated to generate 567 weekday daily
trips, with 65 trips occurring during the weekday AM peak hour (50 entering, 15 exiting), and 67
trips occurring during the weekday PM peak hour (18 entering, 49 exiting).
Future Year LOS. LOS analyses were conducted for future year 2021 conditions at three off-site
study intersections along C Street SW during the weekday AM and PM peak hour. Based on the
analysis results, all off-site study intersections are anticipated to operate at LOS C or better during both
the weekday AM and PM peak hours in 2021 without or with the proposed project.
Mitigation. The payment of transportation impact fees will mitigate project-related transportation
impacts. Transportation impact fees will be determined by the City of Auburn and will need to be
paid at the time of a building permit issuance. As of the date of this study, the adopted City of Auburn
2019 impact fee schedule identifies a non-downtown fee of $2.65 per square foot for the
warehousing land use.

Level of Service
Weekday AM and PM peak hour level of service (LOS) analyses at the study intersections were
conducted at the following three signalized study intersections:
1. C Street SW / WB SR-18 Ramps
2. C Street SW / EB SR-18 Ramps
3. C Street SW / 8th Street SW
The LOS analyses were conducted using the methodologies and procedures outlined in the latest
edition of the Highway Capacity Manual (6th Edition). LOS serves as an indicator of the quality of
traffic flow and degree of congestion at an intersection or roadway segment. It is a measure of
vehicle operating speed, travel time, travel delays, and driving comfort. The LOS methodology is
described in Appendix B. The Synchro Version 10 software package was used to determine LOS.
Existing signal timing used in the analysis was provided by the City of Auburn and WSDOT.
The 2019 existing AM and PM peak hour LOS analysis results for the study intersections are
summarized in Table 2. The 2019 existing LOS worksheets are included in Appendix B.

The City of Auburn collects and reviews collision data to identify intersection and road locations
where potential hazards exist. Potential safety problems are identified using the Safety Priority Index
System (SPIS) methodology. The SPIS score for a location considers three years of data and considers
frequency, collision rate, and severity. Based on CityÊs 2016-2018 SPIS, there were 97 intersections
included and the SPIS scores ranged from 31.32 to 94.88 with a Citywide average of 51.71.
One of the study intersections (C St SW / SR 18 Eastbound Ramps) is included on the SPIS list with
a SPIS Value of 31.32.

FUTURE TRAFFIC CONDITIONS AND PROJECT IMPACTS
Planned Transportation Improvements
This section documents the known transportation improvements planned by the City in the study area.
No planned transportation improvement projects identified in the City of AuburnÊs adopted 2020-
2025 Transportation Improvement Program (TIP) add capacity within the study area or occur within
the analysis horizon for this study.
Project Trip Generation
The trip generation estimate for the proposed 330,000 SF warehouse project was based on the
methodology included in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th
edition for Land Use Code (LUC) 150 (Warehousing).
Table 5 summarizes the resulting weekday daily, AM peak hour, and PM peak hour trip generation
estimates for proposed project. Detailed trip generation calculations are included in Appendix C.

As shown in Table 5, the proposed project is estimated to generate 567 weekday daily trips, with
65 trips occurring during the weekday AM peak hour (50 entering, 15 exiting), and 67 trips
occurring during the weekday PM peak hour (18 entering, 49 exiting).
Project Trip Distribution and Assignment
The distribution of the new project trips generated by the Warehouse project was based on
anticipated travel patterns in the study area and coordination with City of Auburn staff as part of the
Traffic Scoping for the project. The following Table 6 summarizes the resulting general trip distribution
patterns. The distribution of project trips is shown graphically in Figure 4.

Future Traffic Volumes
Future year 2021 Without-Project peak hour traffic volumes were estimated by applying a 2 percent
annual background growth rate to the existing traffic volumes. The 2 percent annual growth rate
was determined to be appropriate based on conversations with the City during the Traffic Scoping
process.
In addition to the background growth rate, traffic from the following pipeline projects were included
in the future without-project peak hour traffic volume estimates:
· Holliday Inn on C Street SW
· Supervalue Warehouse on 15th Street SW
· Sound Transit Parking Garage
The resulting future 2021 without-project weekday AM and PM peak hour traffic volumes are shown
in Figure 6.
The 2021 With-Project traffic volumes were determined by adding the trip assignment from the
proposed development (shown in Figure 5) to the future 2021 Without-Project traffic volumes. The
resulting future 2021 With-Project weekday AM and PM peak hour traffic volumes at the study
intersections are shown in Figure 7.

Future Level of Service
Future year 2021 Level of Service (LOS) analyses were conducted at the three study intersections for
weekday AM and PM peak hour without-project and with-project conditions. Existing intersection
geometry and signal timing was assumed at the study intersections as there are no City-planned
improvements that are expected to be complete by 2021.
The 2021 weekday AM and PM peak hour LOS results at the study intersections without and with
the proposed project are summarized in Table 7. The detailed LOS worksheets are included in
Appendix B.
As shown in Table 7 the study intersections are anticipated to operate at LOS C or better during both
the weekday AM and PM peak hours in 2021 without or with the proposed project.

Site Access Analysis
Level of service analyses were conducted at the proposed site accesses on 8th St SW and C Street
SW for 2021 With-Project traffic conditions in the weekday AM and PM peak hours. The proposed
site access on C St SW was assumed to be restricted to allow only right-in and right-out turn
movements. The LOS analyses were conducted based on the methodology and procedures outlined
in the 6th Edition of the Highway Capacity Manual (HCM) using the Synchro 10.3 software program.
The 2021 With Project AM and PM peak hour volumes at the site access location used in the LOS
analyses are shown in Figure 7.
The weekday AM and PM peak hour LOS results at the site access location for 2021 With-Project
conditions are summarized in Table 8. The LOS worksheets are included in Appendix B.

2. Delay refers to average control delay expressed in seconds per vehicle.
3. V/C = Volume/capacity ratio.
As shown in Table 8, the results of the LOS analyses show that the exiting stop controlled right-turn
movement at the proposed site access is anticipated to operate at LOS B during the weekday AM
and PM peak hours.

MITIGATION
Payment of the City of Auburn transportation impact fee will mitigate project-related transportation
impacts of the proposed 330,000 sf warehouse. Transportation impact fees will need to be paid
at the time of a building permit issuance. As of the date of this study, the adopted City of Auburn
2019 impact fee schedule identifies a non-downtown fee of $2.65 per square foot for the
warehousing land use.

Traffic Impact Analysis

Level of Service Methodology
Level of service calculations for intersections were based on methodology and procedures outlined
in the 2016 update of the Highway Capacity Manual, Transportation Research Board (6th Edition)
using Synchro 10 traffic analysis software.
LOS generally refers to the degree of congestion on a roadway or intersection. It is a measure of
vehicle operating speed, travel time, travel delays, and driving comfort. A letter scale from A to F
generally describes intersection LOS. At signalized intersections, LOS A represents free-flow
conditions (motorists experience little or no delays), and LOS F represents forced-flow conditions
where motorists experience an average delay in excess of 80 seconds per vehicle.
The LOS reported for signalized intersections represents the average control delay (sec/veh) and can
be reported for the overall intersection, for each approach, and for each lane group (additional v/c
ratio criteria apply to lane group LOS only).
The LOS reported at stop-controlled intersections is based on the average control delay and can be
reported for each controlled minor approach, controlled minor lane group, and controlled major-
street movement (and for the overall intersection at all-way stop controlled intersections. Additional
v/c ratio criteria apply to lane group or movement LOS only).
Table B1 outlines the current HCM (6th Edition) LOS criteria for signalized and stop-controlled
intersections based on these methodologies.

1 Source: HCM2010 Highway Capacity Manual, Transportation Research Board, 2010.
2 For approach-based and intersection-wide assessments at signals, LOS is defined solely by control delay.
3 For two-way stop controlled intersections, the LOS criteria apply to each lane on a given approach and to each approach
on the minor street. LOS is not calculated for major-street approaches or for the intersection as a whole at two-way stop
controlled intersections. For approach-based and intersection-wide assessments at all-way stop controlled intersections,
LOS is solely defined by control delay.
