INTRODUCTION
Branch Engineering Inc. has been retained by East Side Baptist Church in Springfield to prepare this
Minor Traffic Impact Study as required in Springfield Development Code to meet the criteria of
Springfield Public Works Department policy S.O.P.P. #T-6.1 and the Traffic Impact Study Scope of
Work, dated July 9, 2009 (see Appendix A), prepared by City of Springfield Transportation staff for
proposed East Side Baptist Church in Springfield, Oregon.
A reduced traffic study has been allowed for this project, as there will not be significant new traffic
generated by the improved worship center. The primary focus of this study is to summarize expected
changes to local traffic patterns.

PROJECT DESCRIPTION
The proposed East Side Baptist Church is located south of Commercial Avenue, north west of 41 st
Street in Springfield. The project consists of a proposed new building (Worship Center) and improved
parking facilities. The church currently has a total of 155 member families, and there is currently a total
of 125 regularly attending families.
The property is identified on Assessor's Map 17-02-31-1-4, Tax Lot 4000. The site is currently occupied
by East Side Baptist Church. The proposed new building size is 11,480 square feet and the new parking
area includes 102 spaces. Construction is expected to begin late in the year of 2009.
Figure 1 illustrates the location of the proposed development.

Parking Analysis
There is a total of 68 parking spaces at the existing East Side Baptist Church in Springfield. Although
the site has adequate parking supply for the typical church demand during regular worships, there is a
nearby parking area across the street that is available for overflow parking during large events. No
vehicle activity was observed in the overflow parking area during regular Sunday services. No bicycle
traffic was observed at the church at the observed services.
A new parking area is proposed to be constructed for visitors and staff parking on the southeast portion
of the site. This new parking facility includes 102 spaces with four accessible spaces.
Site Access
There are two existing driveways on Commercial Avenue. As proposed, a new full-movement driveway
will be constructed on 41 st Street to access the new parking area.
The proposed site plan is shown in Figure 2.

.:. Proposed New Site Access at 41st Street
Both of the above intersections were evaluated as two-way stop controlled.
Crash Analysis
An analysis of crash history was performed for the relevant existing roadways. The most recent three
full years of accident data was evaluated (January I, 2006 through December 31, 2008) as supplied by
the 00 aT Crash Analysis and Reporting Unit. 1t should be noted, that Legislative changes to DMV's
vehicle crash reporting requirements, effective January I, 2004, resulted in fewer property damage only
crashes being eligible for inclusion in the statewide crash data file.

During the period of analysis, there were no crashes reported at the Commercial A venue/41 sl Street
intersection.
The ODOT accident data is included as Appendix B.
Transit Facilities
Currently, the nearest bus stops are located approximately one-quarter of one-mile south of the proposed
development at the Main Street and 42nd Street intersection, and are served frequently by route II.
Non-Motorized Facilities
There are no existing bicycles lanes or sidewalks on Commercial Avenue and it is not expected to have
exclusive pedestrianlbicycle facilities. 41 sl Street has intermittent sidewalks.
Existing Traffic Volumes
Existing Average Daily Traffic (ADT) volumes were obtained from the most recent City of Springfield
Traffic Flow Map. Traffic counts are based on typical weekday 24 hour counts. The ADT in the project
vicinity is as follows:
Roadwav
Commercial Avenue
4151 Street
ADT
2,172
320
ADT for 41 sl Street was estimated to be ten times existing peak hour traffic volumes, as no existing
published ADT data was available. Existing peak hour traffic volumes were determined by manual
traffic counts conducted by Branch Engineering staff in July and August, 2009 (see Appendix C). The
counts were taken between 10:30AM and 12:30PM on a Sunday covering an entire peak service. The
observed traffic volumes are shown in Figure 3.

PROJECT TRAFFIC
Trip Generation
Peak hour trip generation values will not change significantly as a result of the proposed development
and improved parking facilities. However, over time it is expected that membership will increase as a
result of the larger and improved facilities. Therefore, it was conservatively assumed that the proposed
parking lot was full, and all vehicles would enter and leave during the same peak hour, resulting in 102
entering and 102 vehicles exiting at the 4151 Street Access. This simultaneous arrival/departure is not
expected to occur; rather it was used as a simplified conservative operational analysis.
Trip Distribution
The site generated traffic is expected to continue to disburse onto the public roadway system in the same
proportion as the existing conditions. The existing attendees were observed to directionally distribute
to/from the north and south roughly equally. When reviewing church member addresses, it was
confirmed that roughly 50 percent of site generated traffic would have origins/destinations to the north
and 50 percent would be to/from the south.
Traffic Assignment
The site generated traffic was distributed to the adjacent road system and assigned to specific
movements at the relevant intersections based on the above trip distribution assumptions, and existing
operational characteristics in the project vicinity.
Figures 4 and 5 illustrate the assignment site generated traffic and the year 2009 'Build' traffic volumes,
respectively.

OPERATIONAL ANALYSIS
To satisfy the City of Springfield standards, intersection performance was evaluated to determine Level
of Service (LOS) based on delay. Calculations for the unsignalized intersections were performed with
the computer program SYNCHRO 7, by Trafficware.
Level of service, based on vehicle delay, is classified by a letter scale from 'A' to 'F'. LOS' A'
represents optimum operating conditions and minimal delay. LOS 'F' indicates over capacity conditions
causing unacceptable delay. LOS '0' is considered the minimum acceptable level of service by the City
of Springfield. Mitigation measures are often necessary when the level of service is reduced below '0'
as a result of a development.
The LOS determined by average delay per vehicle as established in the Highwav Capacitv Manual. 2000
(HCM) is as follows:

Vehicle queue calculations were performed for the Commercial Avenue/41st Street and Proposed New
Site Access/4l st Street intersections.
The intersection performance analysis and queuing calculations are documented in Appendix 0, and the
results are summarized in the following tables:

All applicable 95th percentile queue lengths were calculated to be reasonable and the projected traffic
was not found to significantly increase queuing. Queues at the Commercial A venue/41 51 Street
intersection will not exceed available storage area between the stop sign and the proposed driveway
location; therefore, the new proposed driveway at 4151 Street is not expected to significantly interfere
with the Commercial Avenue Intersection.

INTERSECTION SIGHT DISTANCE
Minimum safe intersection sight distance is the distance traversed by opposing vehicles at the design
speed of the major road in the travel time needed for a departing side street vehicle to perceive a gap in
traffic, accelerate from a stop, clear the opposing travellane(s), and accelerate without being overtaken
by vehicles already on the major street.
As recommended by AASHTO, the vantage point for departure was considered to be 14.5 feet from the
edge of the vehicle travel way. The driver's eye and the object height were both assumed to be 3.5 feet
above the roadway surface. Site distances measured in the field were compared to the minimum
stopping sight distance recommended by the American Association of State Highway and
Transportation Official's manual, A Policv on Geometric Design of Highways and Street, 2004.
The proposed site access location is near a horizontal curve in 41st Street, and therefore was evaluated to
determine if the existing available line of sight is adequate to serve vehicles entering the roadway at the
subject new driveway location. Per Exhibit 9-55 in the referenced document, the minimum
recommended intersection sight distance in a 25MPH zone for a passenger car to safely depart from this
intersection is 280 feet for an exiting left turn (when looking to the right). The measured available line
of sight exceeded the recommended distance when looking right.
The following table summarizes the available measured line of sight, and lists the recommended
minimum sight distance:

RECOMMENDA liONS AND CONCLUSION
Transit Facilities
The site is adequately served by public transit.
Non-Motorized Facilities
Due to the nature of travel modes utilizing churches, no special pedestrian or bicycle facilities (other
than code requirements) are necessary for the proposed expansion.
Crash Analysis
During the period of analysis, there were no crashes reported at the Commercial A venue/41 5t Street
intersection. No crash reducing measures are necessary to accommodate the proposed development.
Operational Analysis
All studied intersections are projected to operate at acceptable levels of service through the planned
build-out year of2009. All applicable 95th percentile queue lengths were calculated to be reasonable
and the new proposed development was not found to significantly increase queuing or cause vehicles to
significantly interfere with the operations of 41 st Street/Commercial Avenue intersection.
Intersection Sight Distance
The left turn movement at the 41 st Street and Site Access intersection was found to have adequate
available sight distance.
Site Access
As requested in the scope, access point design was considered. The proposed width, depth (throat) were
both considered reasonable and typical. Based on the sight distance, queuing, available gaps, and
considering the result of potentially forcing all exiting vehicles on to 41 5t Street (a local residential
roadway) a right-in/right-out only configuration of the proposed site access is not recommended.
Conclusion
In summary, the result of this analysis indicates, the proposed development will not cause significant
adverse impact on the operating characteristics of the existing adjacent roadway system.

Study Requirements:
General: Provide a Minor Traffic Impact Analysis (TIA) per Springfield Public Works
Department policy S.O.P.P. #T-6.1. This assumes that phase I is the focus of the analysis and
that future development, as depicted in latter phases will not occur within the next two years.
The future phases will require individual land use applications and therefore, traffic impact
analysis at that time.
Project Description: Provide description of project including building size, parking stalls
required, number of trips from ITE estimate, access points and any other transportation related
special features.
Existing Conditions: Include a description of the adjacent street network including lane
configurations, median types, sidewalks, bike lanes, road signs, bus stops, geometry and traffic
controls at the pertinent intersections; Commercial and 4 1st St. Also include any observations or
conclusions that are pertinent to this study.
Project Traffic: Project a worse case occupancy for the project after completion of the new
building by examining current occupancy and applying this density to the entire facility or the
ITE estimate, whichever is worse. With this data, extrapolate the trip distribution to the access
points of the facility and consider the following:
I) Sight distance at the proposed southerly driveway and with respect to curve in 41st Street.
Deterrnine if the location of the driveway is placed in the optimal location with respes;t to
the intersection on the east and curve in 4151 to the west. PR!:-~UarVH .,

Exhihit 9-55. Design Intersection Sight Distance--Case BI-Left Turn from Stop
Sight distance design for left turns at divided-highway intersections should consider multiple
design vehicles and median width. If the design vehicle used to determine sight distance for a
divided-highway intersection is larger than a passenger car, then sight distance for left turns will
need to be checked for that selected design vehicle and for smaller design vehicles as well. If the
divided-highway median is wide enough to store the design vehicle with a clearance to the
through lanes of approximately I m [3 ft] at both ends of the vehicle, no separate analysis for the
departure sight triangle for left turns is needed on' the minor-road approach for the near roadway
to the left. In most cases, the departure sight triangle for right turns (Case B2) will provide
sufficient sight distance for a passenger car to cross the near roadway to reach the median.
Possible exceptions are addressed in the discussion of Case B3.

If the design vehicle can be stored in the median with adequate clearance to the through
lanes, a departure sight triangle to the right for left turns should be provided for that design
vehicle turning left from the median roadway. Where the median is not wide enough to store the
design vehicle, a departure sight triangle should be provided for that design vehicle to turn left
from the minor-road approach.
The median width should be considered in determining the number of lanes to be crossed.
The median width should be converted to equivalent lanes. For example, a 7.2-m [24-ft] median
should be considered as two additional lanes to be crossed in applying the multilane highway
adjustment for time gaps in Exhibit 9-54. Furthermore, a departure sight triangle for left turns
