CITY OF TIGARD
ADJUSTMENT NARRATIVE
DECEMBER 13, 2005
Description of Proposal:
This is a proposal for an adjustment to the access and egress standards of Chapter 18.705, as
allowed by Chapter 18.370.020C(5). The specific section related to the adjustment is
18.705.030H(3), which requires a minimum spacing of access points onto collector streets of 200
feet, and 600 feet for arterials.
The site is located at the northeast comer of SW 72"d Avenue and SW Dartmouth Street. The
combined tax lots 4300 and 4402, on map 1S1-36D, have 200 feet of frontage on SW Dartmouth
Street, and 215 feet of frontage on SW 72"a avenue. The access proposed for redevelopment of
.this site includes two right-in/right-out access points, with one located approximately 150 feet
east .of the street intersection on the Dartmouth frontage, and one located approximately 190 feet
north of the street intersection on 72"d. Both of these locations meet the criteria of
Section 18.705.030H(2), which requires that a driveway must be at least 150 feet from collector
or arterial street intersections. However, it is not possible to meet the access spacing
requirements on either street frontage.
The access onto SW Dartmouth will be a permanent location since there is no opportunity for
alternative driveway locations that more closely meet the Code standard. The right-in/right-out
operation will be implemented by a center barrier in S.W. Dartmouth Ave. This access will be
the "primary" site access, as required by Code section 18.810.030(Q)5, since it is located on the
street of the lesser classification. A Site Design Review application, which will follow this
Adjustment application, will provide building orientation to this frontage and primary signage
will emphasize that the Dartmouth access is primary for the site.
The access onto SW 72nd may be affected by the future improvement of 72"d Avenue, and the
development of property north of the subject site. Consequently, while there will be permanent
site access to 72"d for northbound and eastbound traffic by way of the proposed right/in-right-out
access, the location and configuration of this access point may be revised by the street
improvement or development of the site to the north of the subject property. The site
development plan for the subject site will provide for a cross-driveway to the site to the north,
and a cross easement will be provided. Operation of the right-in/right-out restriction will be
implemented by a center barrier in SW 72 "d Avenue.
City of Tigard Adjustment Narrative
December 13, 2005
Page 2
Both of the proposed access points are needed to provide adequate access to the subject site since
it is recognized that neither can provide full movement access due to vehicle stacking
requirements for the 72"d/Dartmouth intersection. The 72"d Ave. access provides ingress for
west-bound traffic, and egress for other directions, while the access onto Dartmouth provides
ingress for northbound and eastbound traffic, and egress for northbound traffic. Without both
accesses, at least one direction of travel for both ingress and egress would be required to either
execute a "U" turn, or travel out of direction around the large block to resume original direction.
Neither of these alternatives is consistent with efficient traffic management since many drivers
will simply make illegal "U" turns or cut through adjacent parking lots via private driveways to
avoid out of direction travel.
Adjustment Criteria:
Section 18.370.020C(5) provides for Adjustments to access and egress standards based on
certain criteria contained in subsection (b). Since this project cannot meet the access spacing
standards, an Adjustment for each driveway is proposed.
Each of the approval criteria is addressed as follows:
"(1) It is not possible to share access;"
Comment: With respect to the Dartmouth access, the abutting site to the east
has been approved through the City Site Design Review process for development
without a shared access with the site in question. While the abutting property has
not been developed, there is no benefit to redesigning the approved plans to
provide access to Dartmouth, since that property has alternative access onto SW
70th Avenue.
With respect to the access onto 72"d, it is understood that the proposed location
may be shared with the property to the north if possible as a function of future
development of that site.
"(2) There are no other alternative access points on the street in question or from
another street;"
Comment: There clearly is no alternative access point onto Dartmouth for the
reasons noted above. Similarly, the access onto 72"d is located as far north as
possible. If there are future opportunities to improve access onto 72nd by sharing
access with the abutting site development, such opportunities can be considered at
that time. In any case, access to 72nd as a permanent right-in/right-out with a
center barrier will improve accessibility to both the subject site and the site to the
north even if there may be alternative access to SW Clinton through the adjoining
development.
City of Tigard Adjustment Narrative
December 13, 2005
Page 3
"(3) The access separation requirements cannot be met;"
Comment: The site frontage on Dartmouth is approximately 200 feet, which is
the access spacing standard for collectors. Therefore, a driveway onto Dartmouth
could not meet the standard under any, circumstances. Similarly, the distance
between Dartmouth and Clinton is approximately 390 feet, so no access could
meet the 600 foot spacing standard for arterials.
"(4) The request is the minimum adjustment required to provide adequate access;"
Comment: The proposed access points are located as far from the intersection as
possible, so the proposed adjustments are the least necessary to provide adequate
access to the site.
"(5) The approved access or access approved with conditions will result in a safe
access, and;"
Comment: The Traffic Report accompanying this application confirms that the
access points meet safety standards.
"(6) The visual clearance requirements of Chapter 18.795 will be met."
Comment: The Traffic Report also certifies that vision clearance standards will
be met.
Impact Study
Section 18.390.040B(2)(e) requires that Type H Applications include an Impact Study. The only
element of public infrastructure that could be impacted by this Adjustment is the transportation
system. However, since there is no actual site development included in this Adjustment
application there is no impact. A traffic analysis, which will expand upon the accompanying
Traffic Report, will be prepared for the entire project and will address the proposed driveways
and other intersections. The recommendations in this forthcoming study, and the resulting
conditions of approval will address the overall impacts of the project.

Subject: 72"d Avenue at Dartmouth Street - Access Spacing Adjustment
This memorandum is, written to address the traffic operations associated with the requested ad-
justment to the City of Tigard's access spacing. The adjustment is needed to serve a proposed
development in the northeast comer of the intersection of Dartmouth Street and 72"d Avenue.
This document is intended to serve as support for an application for adjustment, which will pre-
cede the actual development application. Accordingly, the analysis described here is intended to
address the operation of the proposed accesses. A full traffic impact study will accompany the
future development application.
Location Description
The property in question has approximately 200 feet of frontage along Dartmouth Street and 215
feet of frontage along 72"d Avenue. Dartmouth Street is classified as a Collector and 72"d Ave-
nue is an Arterial. Since Dartmouth Street is the lesser classification, the primary access is re-
quired to be on this street per City of Tigard code 18.810.030. However, with the limited
amount of frontage, traffic queues from the intersection of Dartmouth Street and 72"d Avenue
extend beyond the property frontage. As such, the driveway is proposed to be limited to right-
turn in and right-turn out movements.
Having a single access that does not provide for left-turning movements is problematic not-only
from a marketability standpoint, but also with respect to traffic operations. Forcing drivers out
of direction generally results in violation of the left-turn restriction or undesirable cut-through
traffic and illegal U-turns in other locations. This activity can compromise the safety and effi-
ciency of the transportation system.
Given the problems associated with a single right-in, right-out access, a second access is pro-
posed along 72"d Avenue. Like the Dartmouth Street driveway, there is insufficient frontage to
avoid traffic queues from the intersection of Dartmouth Street and 72"d Avenue, and this drive-
way is also proposed to be limited to right-in and right-out movements. The possibility does ex-

ist for shared access with properties to the north as they develop, which is addressed in more de-
tail later in this memo.
The City of Tigard has long been planning the installation of a traffic signal at the intersection of
Dartmouth Street and 72°d Avenue, which I understand is slated for construction sometime next
year. SW 72°d Avenue is planned to be a five-lane facility and Dartmouth Street is currently a
three-lane facility east of 72nd Avenue and a five-lane facility to the west. The City's Transpor-
tation System Plan (TSP) classifies Dartmouth Street as a five-lane collector. Right-of-way is
currently being collected and preserved through development along its frontage.
Planned Site Development
Although a specific development plan is not yet proposed on the site, a conceptual site plan ac-
companies this access spacing adjustment request. The plan shows a single two-story building
with a total of 15,400 square feet of floor area. This building will likely be a mix of office and
retail space, but for the purpose of this report, the building was assumed to be occupied entirely
with retail tenants.
The trip generation associated with the development was estimated using data from the manual
Trip Generation, Seventh Edition, published by the Institute of Transportation Engineers (ITE).
Trip rates were used from land-use code 820, Shopping Center. The trip rates are based on the
building floor area.
The trip generation calculations show that the conceptual site development will result in a total
of 58 evening peak hour trips with 28 entering and 30 exiting the site. To the extent that some of
the building space is occupied by office uses, the trip generation will be lower than what is re-
ported here. Detailed trip generation calculations are included in the attached technical appen-
dix.
Future Traffic Volumes
To examine the long-term operation of the proposed site driveways, year 2015 traffic volumes
were estimated. These volumes were estimated by including traffic volumes from several sur-
rounding developments and applying an annual growth rate. Traffic volumes were included
from Dartmouth Square and Tigard Triangle Commons, both of which are approved but unbuilt
developments. Traffic was also included for development on the property in the southeast corner
of the intersection of Dartmouth Street and 72nd Avenue, as well as development on site of the
former Tri-County Center. Traffic volumes from the 1999 traffic impact study prepared by Lan-
caster Engineering were used. The actual development of this property will be different than that
Kim McMillan
December 8, 2005
Page 3 of 5
assumed in the 1999 study, although for this analysis adding the considerable traffic from Tri-
County Center will provide a reasonable approximation of traffic volumes.
In addition to specific developments, the traffic volumes were increased using a growth rate of
three percent per year for 10 years. This growth rate accounts for overall growth in the area as
well as development of smaller surrounding properties. The estimated 2015 traffic volumes are
shown in the attached technical appendix.
Operational Analysis
The operation of the intersection of Dartmouth Street at 72nd Avenue was examined, primarily to
determine future traffic queues on the north and east approaches as they may affect the operation .
of the proposed accesses. The intersection was analyzed using the signalized intersection analy-
sis methodology contained in the 2000 Highway Capacity Manual, published by the Transporta-
tion Research Board.
Since the future configuration of the intersection is not certain at this time, several scenarios
were examined with different lane configurations. The scenarios are illustrated graphically in the
attached appendix and are described as follows:
1. A five-lane section on 72nd Avenue with the existing three-lane section on Dartmouth
Street. For this scenario, it was assumed that 72nd would be built to full width by 2015
but Dartmouth Street would remain in its current configuration.
2. The lane configuration from Scenario 1 with the addition of a second northbound left-
turn lane on 72nd Avenue. The traffic volumes show this northbound left-turning move-
ment to be very heavy and with a single lane, it will be a significant detriment to the ca-
pacity of the intersection.
3. A five lane section on both 72nd Avenue and Dartmouth Street. This was done since the
City's TSP identifies Dartmouth Street a five-lane collector.
4. The lane configuration from Scenario 3 with the addition of a northbound left-turn lane.
The results of the analysis show that traffic queues for all scenarios will extend beyond the pro-
posed accesses. However, since these accesses will only allow right-turning movements, the
queue blockages will only result in on-site delays to drivers exiting the driveways. The drive-
ways are not expected to cause operational problems with the adjacent streets since the restric-
tion of left turns will prevent conflicts that could occur with queue blockages. Included in the
appendix is a figure that summarizes the queuing on the north and east approaches for all scenar-
ios. The queue lengths are illustrated on an aerial photograph that shows their relation to the site
and the proposed accesses.
Kim McMillan
December 8, 2005
Page 4 of 5
Also, the level of service at the intersection is expected to be F during the evening peak hour for
Scenario 1. Each subsequent scenario results in improving levels of service with Scenario 2 be-
ing E, Scenario 3 being D and Scenario 4 being C. Detailed capacity analysis outputs with level
of service and queuing results are provided in the technical appendix. Given the relatively equal
distribution of traffic volumes at the intersection, this location would be a valid candidate for in-
stallation of a roundabout rather than a traffic signal. Given the City's immediate plans for sig-
nalization, a roundabout option was not explored in this analysis.
As mentioned previously, it is expected that with development north of the site, access to 72nd
Avenue could be made available to this site farther north through access agreements with adja-
cent development. Some consideration was given to the possibility of a future full-movement
access being located opposite the Winco driveway. However, the analysis clearly shows that for
nearly all scenarios, queues will extend beyond this location. It may be necessary to locate the
first full movement intersection north of Dartmouth Street at Clinton Street.
It is expected that to effectively restrict left turns at the site accesses, raised concrete curbs will
be needed in both 72nd Avenue and Dartmouth Street. The design of these curbs can be ad-
dressed in more detail later in the development process, but it is expected that they will need to
be constructed as temporary features. The presence of a curb or barrier to restrict left turns will
be permanent, but the near-term barriers themselves may be temporary.
The upcoming capital project at the intersection of 72nd Avenue and Dartmouth Street may in-
clude raised curbs, access control, and some amount of lane realignment at the intersection. This
will affect any barriers or curbs that would be placed prior to the capital improvements.
Given the likelihood of access restrictions on most if not all driveways near the intersection of
Dartmouth Street and 72nd Avenue, it is recommended that when designing the intersection im-
provements, the City give consideration to allowing U-turns on some approaches. This practice
is becoming more prevalent on arterial and collector facilities near major intersections where ac-
cess control exists. The Oregon Department of Transportation (ODOT) has design guidelines for
allowing U-turns at signalized intersections.
Sight Distance
Sight distance measurements were conducted at the proposed site access locations. The meas-
urements were done in accordance with the intersection sight distance standards contained in the
Fifth Edition of A Policy on Geometric Design of Highways and Streets, published by AASHTO.
The driver's eye height and the height of an oncoming object were both taken to be 3.5 feet and
the measurements were taken from a point 15 feet behind the edge of the adjacent travel lane.
The posted speed on Dartmouth is 35 mph, requiring 390 feet of sight distance. The posted

speed on 72nd Avenue is 30 mph, requiring at least 335 feet. Since both accesses only allow
right-turns out of the site, sight distance is only needed for one direction.
Looking to the east from the Dartmouth Street access, sight distance is available well in excess
of 390 feet. Looking to the south from the 72"d Avenue access, the intersection at Dartmouth
Street is clearly visible. The proposed access will be over 200 feet from the intersection, afford-
ing drivers exiting the driveway adequate separation from vehicles turning northbound onto 72nd
Avenue. Looking through the Dartmouth Street intersection, sight distance is in excess of 335
feet.
It is recommended that the necessary sight distance triangles be maintained through site design
and construction. Parking and building locations should not block line of sight from the drive-
ways and any vegetation near the driveways should be limited in height.
Summary & Conclusions
The results of the analysis show that traffic queues from the intersection of Dartmouth Street at
72nd Avenue will extend beyond both proposed access locations. However, since these accesses
will only allow right-tuming movements, the queue blockages will only result in on-site delays
to drivers exiting the driveways. The driveways are not expected to cause operational problems
with the adjacent streets, even in the future when queues routinely extend beyond the driveways
during the peak hours.
The analysis also shows that the intersection of the Winco driveway with 72nd Avenue will be
blocked by traffic queues in the future. This intersection may need to be limited to right turns in
and right turns out if the City wishes to restrict left-turning movements within the influence of
the traffic signal.
Since access along both streets will likely need to be restricted, it is also recommended that the
City examine the possibility of allowing U-turns at the intersection of Dartmouth Street and 72nd
Avenue when the traffic signal and associated improvements are designed and constructed next
year.
If you have any questions or need anything further, please don't hesitate to call.
NOTE.
Traffic volumes derived assuming development of the subject site, the
adjacent Dartmouth Square, Tigard Triangle Commons, the site of the
former Tri-County Center (based on trip generation used in 1999 traffic
study by Lancaster Engineering), and the property in the SE corner of
72nd Avenue and Dartmouth Street. Additionally, a 37. per year growth rate
was applied for 10 years to account for other surrounding development.
