SUBJECT: Update on Waluga Neighborhood Traffic Assessment and LOC 50.02.002.2.d
(LU 19-0039)
DATE: July 17, 2019 MEETING DATE: July 22, 2019
INTRODUCTION
The City Engineer will update the Planning Commission on the traffic assessment recently
completed in response to a request from the Waluga Neighborhood Association (Waluga).
BACKGROUND
Waluga sent a letter to the City and Planning Commission on May 29, 2019, asking for measures
to mitigate their concerns regarding traffic on Quarry Road, specifically that the City implement
the traffic management provisions of LOC 50.02.002.2.d. Quarry Road is the singular north-
south neighborhood collector within the Waluga boundaries, south of Kruse Way.
As discussed at the Planning Commission's July 8, 2019 work session on Annual CDC
Amendments (LU 19-0033), the City is currently reviewing LOC 50.02.002.2.d and will be
recommending code amendments to clarify the regulations and remove redundancies with
other code requirements. The Planning Commission will review the proposal later this year.
DISCUSSION
Please see the attached Engineering Department report for the details of the analysis.
RECOMMENDATION/NEXT STEPS
No Planning Commission action is proposed or recommended at this time. The Transportation
Advisory Board would be the appropriate body to review any new proposal for traffic calming
on Quarry Road or elsewhere. The City (staff and Development Review Commission) would also
consider the need for mitigation with any future development application in the area.

QUARRY ROAD TRAFFIC ASSESSMENT - July 2019
SUMMARY
The Waluga Neighborhood Association has asked the City and Planning Commission to mitigate
their traffic concerns regarding Quarry Road, claiming that the roadway volumes have
significantly increased over the past several years because of recent development activity in the
area. However, the City has collected data that shows volumes are lower now than ten years
ago, and that speeds are relatively stable. Data also indicates that some cut-through traffic
may be occurring, but that physical deterrents may cause other negative impacts for the
majority of people who need to use Quarry for local access.

BACKGROUND
The Waluga Neighborhood Association sent a letter to the City and Planning Commission on May 29,
asking for measures to mitigate their concerns regarding traffic on Quarry Road. Quarry Road is the
singular north-south neighborhood collector within the Waluga boundaries, south of Kruse Way.
Over the years, numerous improvements have been made to address neighborhood concerns; a
roundabout was installed in 2003/04. Stop signs, speed bumps, a raised pedestrian crossing, and other
modifications have been incorporated to help maintain the residential neighborhood collector aspects
of the street. In 2014, the Kruse Village development was opened at the roundabout location, and the
neighborhood has been concerned about the potential impacts. See Attachment 1, Quarry Road Traffic
Control Devices,for a complete overview of the roadway.
The City has taken speed,volume, and vehicular classification counts on Quarry for over 15 years. In
response to comments about perceived cut-through traffic from drivers outside the adjacent area,the
City also recently conducted a study to determine what cars might be diverting off Kruse or Boones
Ferry and using Quarry as a potential "cut-through". A summation of the traffic analyses is provided in
this report.
QUARRY ROAD CHARACTERISTICS
It's important to note key aspects about the roadway characteristics. Quarry Road is:
• Classified as a Neighborhood Collector in the Transportation System Plan
• It starts at the north at the Carman/Meadows/Quarry roundabout, and runs approximately 3,100
feet south to Boones Ferry Road.

• The north terminus is a roundabout at Carmen/Meadows
• The south terminus is a restricted right-in-right-out only diverter at Boones Ferry Road, restricting
left-turn movements from northbound Boones Ferry, and left-turns from Quarry on to Boones Ferry.
TRAFFIC VOLUME HISTORY
The neighborhood association has been concerned that the traffic volumes have increased on Quarry
over the past several year, particularly with recent development. However,the data is showing
otherwise. Volume counts have been taken on Quarry for over 15 years.
Average Daily Trips—3 Locations, by year
%Change
ID Location 2003 2009 2014 2016 2017 2019 10 years
79 Quarry—Galewood to Douglas 3447 4885 4792 4609 4104 -16%
80 Quarry - Douglas to Oakridge 4320 4251 4085 3668 -15%
88 Quarry—Oakridge to BFR 2075 2714 n/a
Key notes
• Along the north portion of Quarry(between Galewood and Oakridge),the actual volumes have
decreased over the past 10 years by approximately 15-16%.
• The volumes near the south end (between Oakridge and Boones Ferry)went up from 2003 to 2016,
but there is not recent data to compare over the past ten years.The general trend is downward
since 2009, so it may have gone down as well.
• The Kruse Village development was finished in 2014, and the volumes near the north end have
dropped since that time.
In comparison, counts on other higher classification roads have had significant increases over the past
10 years. For example:
Major Collectors:
• Meadows—22% increase
• Carman— 19 to 24% increase
• Bryant (south of BFR)—15% increase
Major Arterials
• Kruse Way—4 to 24% increases
• Boones Ferry Road—0 to 3%decrease
A full picture of the traffic volume counts throughout the area is provide in Attachment 2, Waluga NA
Traffic Count Data Summary Sheet. It is clear from the data collection is that volumes have either
stayed flat or increased significantly on nearby higher level classification roadways, and the volumes on
Quarry have actual gone down in the past 10 years.

SPEEDS
Quarry Road has posted speed signs for 25 mph. The Police Department deploys the speed reader
boards on a regular basis along Quarry. Data collection from the City's count/speed studies indicates
that the speeds on Quarry have remained steady over the past five years. The 85th percentile (meaning
85% of cars are traveling at this speed or less) has dropped from 26 to 24, and 29 to 28 mph in various
segments. While some drivers are speeding,the vast majority are not, and are in fact following the
posted speed limit.
ORIGIN-DESTINATION TRAVEL STUDY
Earlier this spring,the City collected travel study information using license plates and detection. The
project recorded the time it took for a license plate to be detected in one location, and then show up in
another. This was conducted during a two-hour PM peak on May 14, 2019.
The attached summary indicates that, in general,the percent of possible cut-through from Kruse to
Boones Ferry using Quarry is about 16%of the total Quarry Road volumes during the peak hours. This
means that rather than stay on Kruse Way and Boones Ferry Road, some drivers are using Quarry
instead. However, what can't be determined from this study is whether or not the destination for the
apparent cut-through is actually close by or on Boones Ferry Road, or in adjacent neighborhoods. The
study was not far-reaching and only shows a portion of the full story.
MITIGATION OPTIONS
Diverters
The Waluga Neighborhood Association has often requested physical devices to keep the "cut-through
traffic out". Unfortunately,there are no physical devices that can be installed to specifically eliminate
potential "cut-through" traffic. What applies to one car/driver applies to all users. A diverter for
instance would affect everyone who needs to use the road, including those who access their homes via
Quarry, and could cause significant out-of-direction travel for those users. So while it could help
eliminate up to 15%of the peak hour traffic,the rest of the users (approximately 85%of the drivers)
would have to find another route, increase their drive time, and impact some other nearby local
residential street. Staff does not believe this is a viable solution.
Permanent Speed Reader Board
As part of the Boones Ferry Road project that is currently under construction, a permanent speed reader
board is being installed just north of the Harvey/Heritage intersection with Quarry, prior to the all-way
stop. This is a mitigation for potential impacts from the construction work. The 2019 speed study
indicates that nearly 94%of the traffic was traveling at or below the speed limit in this section. The
effectiveness of the speed reader board installation will be determined at various intervals over the next
several years while construction is underway on Boones Ferry Road.

Dear Mr. Lazenby, Siegel and Heape:
Jim Newcomer
Rett Russell The Waluga Neighborhood Association ("WNA") requests the City of Lake Oswego
("City")to implement traffic measures that mitigate increases in traffic volume that
Carol Lavender greatly exceed prior forecasts, make changes as required by Lake Oswego Community
Mark Smith Code (LOC) and are consistent with the City of Lake Oswego Transportation System Plan
(TSP).
Katherine Purtzer
Board Members As you may or may not be aware,the WNA has worked closely with the City over the last
at Large 30 years to assure that Quarry Road, a Neighborhood Collector, continues to work as
Dick Benedetti such and that negative effects,such as cut-through traffic due to neighboring
Andrea Platt developments are mitigated. This has resulted in many modifications to the street—stop
signs, speed bumps,turn constraints, signs,etc.
Leslie Morgan
Unfortunately,these have not been enough as we are seeing increases in traffic,
especially during the PM Peak hours continuing to add proportionately more trips to Quarry Road than
either Carman or Kruse Way. For example, based on the Traffic Impact Analysis from the Mercantile
Redevelopment (LU 18-0026)the roundabout at Carman/Meadows/Quarry is at a Level of Service
("LOS") "E" and projected to LOS "F"within 2 years. Per 50.02.002.2.d Traffic Management
Requirements for Specific Locations requires specific actions when this occurs.
We are asking the City to help lead the effort to mitigate this situation. The WNA wants to assure
Quarry Road maintains acceptable vehicle levels, assure it functions as a Neighbor Collector and mitigate
non-local, cut through traffic.
The WNA will work with the City as needed to achieve workable solutions. We ask the City to please
provide us a response by June 15th (or commit to a date)for what needs to occur in order to bring this
situation back within code compliance.
Best Regards,
Cheryl Uchida,WNA Chair
