1. DEVELOPMENT IDENTIFICATION
Gibson Traffic Consultants, Inc. (GTC) has been retained to provide a traffic impact analysis for
4th Dimension Building development. This report is intended to provide the City of Renton with
the necessary traffic generation, trip distribution and intersection analysis to facilitate their review
of the development. The 4th Dimension Building development is located in the northeast corner of
the intersection of NE 4th Street at Bremerton Avenue in the City of Renton. A site vicinity map is
included in Figure 1. The development is proposed to consist of 24 apartments with 6,237 square-
feet (SF) of commercial space.
Brad Lincoln, responsible for this report and traffic analysis, is a licensed professional engineer
(Civil) in the State of Washington and member of the Washington State section of ITE.
2. METHODOLOGY
The analysis contained in this report is based on the City of Renton Policy Guidelines for Traffic
Impact Analysis for New Development and comments identified in the February 15, 2018 pre-
application meeting, specifically the signal warrant and level of service analysis for the intersection
of NE 4th Street at Bremerton Avenue. Additionally, the access to Bremerton Avenue has been
analyzed under the future with development conditions. The signal warrant analysis has been
evaluated based on the Manual on Uniform Traffic Control Devices (MUTCD). The level of
service analysis has been performed in accordance with the 2010 Highway Capacity Manual
(HCM). Congestion is generally measured in terms of level of service (LOS). Road facilities and
intersections are rated between LOS A and LOS F, with LOS A being free flow and LOS F being
forced flow or over-capacity conditions. A summary of the level of service criteria is included in
Table 1.

The level of service at two-way stop-controlled intersections is based on the average delay for the
stopped approach with the highest delay. The level of service at all-way stop-controlled
intersections and signalized intersections is based on the average delay for all vehicles. The level
of service analysis for unsignalized and signalized intersections has been performed utilizing the
Synchro 10.2, Build 0 software.
The trip generation calculations for the development are based on average trip generation rates
published in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition
(2017).
1 Source: Highway Capacity Manual 2010.
LOS A: Free-flow traffic conditions, with minimal delay to stopped vehicles (no vehicle is delayed longer
than one cycle at signalized intersection).
LOS B: Generally stable traffic flow conditions.
LOS C: Occasional back-ups may develop, but delay to vehicles is short term and still tolerable.
LOS D: During short periods of the peak hour, delays to approaching vehicles may be substantial but are
tolerable during times of less demand (i.e. vehicles delayed one cycle or less at signal).
LOS E: Intersections operate at or near capacity, with long queues developing on all approaches and long
delays.
LOS F: Jammed conditions on all approaches with excessively long delays and vehicles unable to move at
times.
2 When demand volume exceeds the capacity of the lane, extreme delays will be encountered with queuing which may
cause severe congestion affecting other traffic movements in the intersection.

3. TRIP GENERATION
Trip generation calculations for the 4th Dimension Building development have been performed
utilizing data published in the Institute of Transportation Engineers (ITE) Trip Generation Manual,
10th Edition, Volume 2: Data (2017). The average trip generation rates for the following ITE Land
Use Codes (LUC) have been utilized in the trip generation calculations:
LUC 221, Multifamily Housing (Mid-Rise) – 24 apartments units
LUC 820, Shopping Center – 6,237 SF of retail space
LUC 210, Single-Family Detached Housing – 1 existing residence to be removed
ITE Land Use Code 221 has been utilized for the 24 proposed apartments since they will include
3 stories, which meets the criteria of ITE Land Use Code 221. It is also important to note that ITE
Land Use Code 820 includes a range of retail/commercial uses, including restaurants, banks and
other uses. ITE also publishes a pass-by rate for ITE Land Use Code 820 to account for existing
trips along the roadway using the site. This pass-by rate, 34%, has been applied to the daily and
peak-hour trip generation calculations. The trip generation of the 4th Dimension Building
development is summarized in Table 2.

The 4th Dimension Building development is anticipated to generate approximately 277 new
average daily trips with 12 new AM peak-hour trips and 26 new PM peak-hour trips. The trip
generation calculations are included in the attachments.

4. TRIP DISTRIBUTION
The 4th Dimension Building development is proposed to have one access to Bremerton Avenue
near the north edge of the property. The distribution of trips is based on existing count data and
surrounding uses. It is anticipated that 70% of the development’s trips will travel to and from the
west along NE 4th Street. The remaining 30% of the development’s trips are anticipated to travel
to and from the east along NE 4th Street. It is possible that trips generated by the development
could travel to and from the north along Bremerton Avenue; however, the distribution represents
the highest potential impact to the study intersections. Detailed trip distributions for the AM peak-
hour and PM peak-hour are shown in Figure 2 and Figure 3, respectively.
5. INTERSECTION LEVEL OF SERVICE ANALYSIS
The intersection of NE 4th Street at Bremerton Avenue was identified during the pre-application
meeting for the development and represents the only off-site intersection impacted with 20 peak-
hour trips. Additionally, the site access to Bremerton Avenue has been analyzed. The development
will not impact any intersections during the AM peak-hour with 20 peak-hour trips and therefore
the analysis in this report has been performed for the weekday PM peak-hour.
5.1 Turning Movement Calculations
The 2018 existing PM peak-hour turning movements at the study intersections were collected by
the independent count firm IDAX in July 2018. The 2018 existing turning movements at the study
intersection are shown in Figure 4.
The future analysis has been performed for the year 2024, which represents a 6-year horizon period
and is beyond when the development is anticipated to be constructed. The 2024 baseline turning
movements have been calculated by applying a 2.5% annually compounding growth rate to the
2018 existing turning movements. The growth rate is based on a comparison of daily volumes
published by the City of Renton for the year 2012 and daily volumes collected as part of this report.
The 2024 baseline turning movements at the study intersection are shown in Figure 5. The 2024
future with development turning movements at the study intersections have been calculated by
adding the development’s trips to the 2024 baseline turning movements. The turning movements
at the site access are based volumes from the adjacent intersection of NE 4th Street at Bremerton
Avenue. The 2024 future with development turning movements are shown in Figure 6.

5.2 Level of Service Calculations
The 2018 existing level of service calculations have been performed utilizing the existing
channelization, existing intersection control and peak-hour factors and heavy vehicle factors from
the 2018 turning movement counts. The 2024 baseline and 2024 future with development level of
service analysis does not include any changes to the existing channelization or control, such as a
signal or roundabout. Additionally, the intersection of NE 4th Street at Bremerton Avenue does not
include utilization of the center turn lane on NE 4th Street by left-turns from Bremerton Avenue
(i.e. a 2-stage left-turn movement) due to the eastbound and westbound left-turn volumes on NE
4th Street. The level of service summary is included in Table 3.

The analysis shows that the intersection of NE 4th Street at Bremerton Avenue currently operates
at LOS F for both approaches and will remain at LOS F under the 2024 baseline and 2024 future
with development conditions. It is important to note that the northbound approach, which the
development is not anticipated to add any trips to operates worse than the southbound approach,
which will have the highest impact of the development. The intersection of NE 4th Street at
Bremerton Avenue is discussed in more detail later in this report. The site access is anticipated to
operate at acceptable LOS A under the 2024 future with development conditions. The level of
service calculations are included in the attachments.
5.3 Signal Warrant Analysis
The City of Renton identified that a signal warrant analysis was required for the intersection of NE
4th Street at Bremerton Avenue. The signal warrant analysis has been performed based on MUTCD
guidelines. The signal warrant has been performed for Signal Warrant 1 and Signal Warrant 2,
which are based on hourly volumes and are the most applicable for an existing intersection. Hourly
traffic volumes were collected on all approaches by IDAX in July 2018. It is important to note that
the hourly volumes on the northbound approach were collected south of the driveways closest to
NE 4th Street. The northbound approach volumes have therefore been adjusted based on a
comparison to the PM peak-hour turning movement count to include vehicles utilizing from the
driveways.
4th Dimension Building Traffic Impact Analysis
Gibson Traffic Consultants, Inc. July 2019
info@gibsontraffic.com 12 GTC #18-102
Signal Warrant 1
MUTCD Signal Warrant 1 is based on the 8 hours with the highest volumes. Signal Warrant 1 is
based on minimum vehicular volumes, interruptions of continuous flow and a combination of the
prior two methods along the major roadway. The posted speed through the intersection is 35 mph
therefore 100% of volume thresholds identified in MUTCD is used.
The signal warrant analysis shows that the intersection will meet 1 hours of the required 8 hours
for Part 1A, up to 5 hours of the required 8 hours for Part 1B and up to 3 hours of the required 8
hours for Part 1C. The intersection will therefore not meet MUTCD Signal Warrant 1.
Signal Warrant 2
Signal Warrant 2 is based on any 4 hours throughout the day meeting the volume thresholds
provided in volume curves. The northbound and southbound approaches include separate right-
turn lanes, which could reduce the volume thresholds for the minor legs. However, the northbound
and southbound approaches have been evaluated as a single-lane approach to represent a
conservative signal warrant analysis.
The volume data shows that the intersection will only meet 3 hours of the required 4 hours for
Signal Warrant 2. The intersection will therefore not meet MUTCD Signal Warrant 2.
Signal Warrant Conclusions
The signal warrant analysis shows that the intersection of NE 4th Street at Bremerton Avenue does
not currently meet the thresholds for Warrant 1 or Warrant 2 and is not anticipated to meet the
thresholds under the 2024 baseline or 2024 future with development conditions. The 4th Dimension
Building development should therefore not be conditioned to install a signal at this intersection.
The signal warrant data and calculations are included in the attachments.
6. CRASH DATA
Crash data for the intersection of NE 4th Street at Bremerton Avenue, including 500 feet along
each leg, was obtained from WSDOT for the period from January 1, 2013 through the most recent
data available. This time period represents approximately 5.5 years. The crash data showed a total
of 23 crashes in the study area, but only 12 occurred at the study intersection and only 11 were
associated with the study intersection. The other 11 crashes occurred at adjacent driveways and
were not associated with the study intersection. The one crash that occurred at the study
intersection, but was not associated was due to vehicles queued back from the adjacent signalized
intersection of NE 4th Street at Duvall Avenue.
The 11 crashes that occurred at the intersection of NE 4th Street at Bremerton Avenue are all
associated with left-turns, both from the major and minor approaches. The crash rate is
summarized in Table 4.

Table 4: Crash Rate Summary
Crashes Years Crash Rate per
Year Daily Trips Crash Rate per
Million Entering Vehicles (MEV)
11 5.5 2 29,000 0.19
The crash rate shows that there are 2 crashes per year and a crash rate of 0.19 per MEV. Both of
these rates are below typical crash rates for an unsignalized intersection. Additionally, there were
no fatalities reported during the study period. The crash data is included in the attachments.
7. NE 4TH STREET AT BREMERTON AVENUE
The intersection of NE 4th Street at Bremerton Avenue currently operates at LOS F and is
anticipated to remain at LOS F under the 2024 baseline and 2024 future with development
conditions. The northbound approach operates with considerably more delay than the southbound
approach and it is important to note that the 4th Dimension Building is not anticipated to add any
trips to the northbound approach. There are several options to improve the operations of the
intersection, including:
Restricting the northbound and southbound approaches to right-turn only, while still
allowing left-turns from NE 4th Street
Restricting the intersection to right-turn only (i.e. restricting left-turns from NE 4th Street)
Both of these changes would also reduce the potential for the crash type that historically occurs at
this intersection. It is important to note that the 4th Dimension Development does not cause the
deficient level of service and therefore the development should only be responsible for the
proportionate share of the impact. The development is anticipated to account for 30 of 2,718 PM
peak-hour trips at the intersection under the 2024 future with development conditions. The 4th
Dimension Building therefore has a proportionate share impact to the intersection of NE 4th Street
at Bremerton Avenue of 1.10%. It will be the decision of the City of Renton to determine if any
improvements to the intersection of NE 4th Street at Bremerton Avenue are required and what those
improvements are.
8. PEDESTRIAN FACILITIES
The existing pedestrian facilities in the area include sidewalks along both sides of NE 4th Street.
Bremerton Avenue has sidewalks along the west side and along the east side north of the
development site. There is not currently sidewalk along the development’s Bremerton Avenue
frontage. The development will include frontage improvements along Bremerton Avenue to
complete the pedestrian connectivity in the site vicinity.

9. TRANSPORTATION IMPACT FEES
The transportation impact fees for the 4th Dimension Building are based on the current impact fees
and could increase when the fees are actually paid. The current fees are $3,358.55 per apartment
unit and $13.29 per square-foot of shopping center. The credit for the existing single-family
residential unit is $5,430.85. The traffic mitigation fees are summarized in Table 5.
Table 5: Transportation Impact Fee Summary
Use Size Fee Basis Impact Fee
Apartment 24 units $3,358.55 Unit $80,605.20
Shopping Center (Retail) 6,237 SF $13.29 SF $82,889.73
Single-Family -1 unit $5,430.85 Unit $-5,430.85
TOTAL $158,064.08
The total traffic mitigation fees for the 4th Dimension Building is $158,064.08.
This does not account for any potential proportionate share costs for improvements to the
intersection of NE 4th Street at Bremerton Avenue.
10. CONCLUSIONS
The 4th Dimension Building is proposed to consist of 24 apartments and 6,237 SF of retail space
replacing 1 existing single-family residential unit. The development is anticipated to generate 277
new average daily trips with 12 new AM peak-hour trips and 26 new PM peak-hour trips. The
intersection of NE 4th Street at Bremerton Avenue is the only off-site intersection that is anticipated
to be impacted with 20 peak-hour trips. The intersection currently operates at LOS F and will
remain at LOS F under the 2024 baseline and 2024 future with development conditions. The trips
generated by development represent 1.10% of the 2024 future with development volumes at the
intersection and this should be the proportionate share of any off-site improvements required for
the 4th Dimension Building development. The current transportation impact mitigation fees total
$158,064.08; however, the actual fee will be determined when a complete building permit
application is filed.
