Traffic Impact Study
ThompsonEngineers Tanner Creek Subdivision
Traffic and Civ;r Inc. Meridian, Idaho
Introduction
Thompson Engineers, Inc. has been retained to prepare a traffic impact study (TIS) for the proposed
Tanner Creek Subdivision located on Waltman Road in Meridian, Idaho, as shown in Figure 1. The TIS
evaluates the potential traffic impacts resulting from the development and make recommendations for
mitigation of the impacts. The scope of this report was determined through coordination with the Ada
County Highway District (ACRD) and was prepared in accordance with ACHD Policy, Section 7106 —
Traffic Impact Studies.
Proposed Development
1. Tanner Creek Subdivision is a proposed residential development containing 85 single-family
detached housing units, 44 townhouses, and 280 apartments with an expected 2022 build -out year.
2. Based on ITE Trip Generation Manual, the development is estimated to generate approximately 2,928
trips per day, 226 trips during the AM peak hour and 282 trips during the PM peak hour.
The development is not expected to retain internal trips within the site or generate pass -by trips.
'! All trips generated by the development are expected to be made by personal vehicles.
The estimated site traffic distribution patterns are:
• 10% west of the site
• 90% east of the site
3. All proposed internal roadways are projected to carry less than 1,000 vehicles per day.
4. The proposed driveway locations on Waltman Lane generally meet the ACHD's access spacing and
design.
5. This project will connect the existing subdivisions to the west to Waltman Lane. This will provide
shorter travel route to many destinations for many trips originating within the existing subdivisions.
As a result, we anticipate that traffic from the existing subdivisions will redistribute and use Waltman
Lane instead of Linder Road to access the transportation system
6. The existing subdivisions to the west are currently served only by Linder Road to access the
transportation system. There are more than 700 homes in the traffic shed. The connection to
Waltman Lane will provide a critical link to the transportation system and will greatly increase the
safety of the existing subdivisions.
Proposed osed itigation for 2017 Existing Traffic
7. All of the intersections in the study area operate at an acceptable level of service under existing traffic
conditions. No mitigation is necessary.
8. All of the roadway segments studied operate below the recommended maximum threshold for local or
collector roads. Not mitigation is necessary.

Proposed Mitigation for 2022 (Build -Out Year) Background Traffic
9. For background traffic conditions, it was assumed that the connection from the existing subdivisions
to the west to Waltman Lane was complete and traffic will redistribute. With traffic growth and
redistributed traffic, all of the intersections are anticipated to operate at an acceptable level of service.
No mitigation is necessary.
10. All of the roadway segments studied are anticipated to operate below the recommended maximum
threshold for local or collector roads. No mitigation is necessary.
Proposed Mitigation for 2022 (Build -Out Year) Total Traffic
11. With the addition of site traffic added to background traffic, all of the intersections are anticipated to
operate at an acceptable level of service. No mitigation is necessary.
12. All of the roadway segments studied are anticipated to operate below the recommended maximum
threshold for local or collector roads. No mitigation is necessary.

®ad System
r A brief description of the existing roadways and intersections within the study area is described below.
The roadway functional classification is based on COMPASS 2040 Functional Classification Map, which
does not include collector or local streets.
Waltman Lane is not classified in the COMPASS snap. Waltman Lane functions as a collector street
with a posted speed limit of 25 miles per hour (mph). In front of the site, it has one travel lane in each
direction with a rural section without curb, gutter, sidewalk or designated bike lane. Waltman Lane ends
just to the west of the site.
Linder Road is classified as a principal arterial road in the COMPASS map with a posted speed limit of
E< 35 mph. It has one lane in each direction with a rural section with curb, gutter, and sidewalk in the
vicinity of this project. Linder Road terminates at I-84 on the south end.
Elder Drive, Gander Drive, Pelican Way, Pintail Drive, and Waltman Drive are not classified by
COMPASS. They function as local roads with front on housing access. These streets do not have posted
speed limits, but the City if Meridian City Code designates a speed limit of 20 mph on local roads. All of

the roads are urban sections approximately 36 feet wide, with curb, gutter and sidewalk. All of the roads
permit on street parking.
Waltman/Central and Main/Meridian intersection is a signal controlled intersection. Waltman Lane
has two left turn lanes, one through lane, and one right turn lane at the intersection. This intersection is
the terminus of the Main Street and Meridian Road one way couplet. All approaches have multiple lanes.
Gander Drive and Linder Road intersection is a stop -controlled intersection with stop sign on the
Gander Drive. The intersection has one shared lane for all movements on all approaches.
Existing Traffic Volumes
AM and PM peak hour traffic counts were obtained at the study intersections on October 16, 2017. The
peak our intersection turning movement counts were collected on a weekday for a 2 -hour period at 15 -
minute intervals between 7:00 and 9:00 during the AM peak travel period hour and between 4:00 and
6:00 during the PM peak travel period, which are included in the appendix. Existing peak hour traffic
volumes are summarized in Figure 3.
24-hour counts were also obtained for the study area roadway segments — summarized in Table 1.

Intersectio Crash Data
The most current five-year crash data (2011-2015) was obtained from the Local Highway Technical
Assistance Council (LHTAC) website (http://gis.lhtac.org/safety. No accidents were reported on
Waltman Lane. Only two accidents were reported in the subdivision to the west along the anticipated
travel routes.
Roadway Network Improvements
At the time of this study, the ACHD 2016 Capital Improvement Plan (CIP) included a project to widen
Linder Road from 2 lanes to 5 lanes. The ITD Idaho Transportation Investment Program (ITIP) FY2017-
2021, FY2018-2024 (Draft) included a plan to construct an overpass of Linder Road over Interstate 84.
These projects are in the 2031-2035 planning period and are unfunded.
This project will connect the subdivision to the west to Waltman Lane. This will provide a shorter route
to destinations such as shopping centers and jobs, as well as shorter access to the interstate. It is
anticipated that this improvement will impact existing travel patterns.
Background Traffic
The areas adjacent to the site are mostly build -out. The following annual growth rates were used to
estimate the traffic growth for the study area roadways and intersections:
• 1.5% on Meridian Road, and Main Street
• 1.0% on Waltman Lane and Central Drive
• 0.0% on the local roads west of the site.
• 0.5% on Linder Road
As noted above, the connection of Ruddy Drive to Waltman Lane will change the travel patterns of
people in the subdivision to the west. The redistributed traffic is assigned to the transportation system in
the background phase of this study.
Figure 4 shows the 2022 build -out year redistributed background turning movement traffic for the AM
and PM peak hours.

Site Traffic
Trip Generation
Site trip generation is usually estimated using the procedures recommended in the latest edition of the
Trip Generation Manual (9`t' edition), published by the Institute of Transportation Engineers, in the
absence of site-specific data. The site trip generation is obtained by applying the average trip generation
rates obtained from the Manual for the proposed land use within the development. Table 2 summarizes
the site trip generation. At full build -out, the development is estimated to generate approximately 2,928
trips per day, 226 trips during the AM peak hour and 282 trips during the PM peak hour.
'r.161. I — R„ilrl_(hit .Cita Trin f_'nnni•atinn Cnmmai-v
The previous application for a retail and office development generated 10,300 trips per day, 975 of which
occurred in the PM peak hour. The ACHD staff report did not provide AM peak hour trip generation.
The proposed development will generate less than 30% of the volume of traffic than the former
development proposal.
Trip Capture
Based on the proposed land use, the development is not expected to retain trips within the site at full
build -out. No trip reduction for internal capture trip was assumed in the traffic impact analysis.
Pass -by Trips
The development is residential and is not expected to attract pass -by trips. No pass -by trips were assumed
in the traffic impact analysis.

Modal Split
The development is not expected to generate trips made by other modes beside personal and commercial
vehicles. All trips generated by the development were assumed to be made by personal and commercial
vehicles.
Trip Distribution and Assignment
In order to determine the impacts, trips generated by the development must be distributed and assigned to
the transportation system. Site traffic was distributed and assigned to the external roadway system based
on the current travel patterns, site layout and the general location of the site within the area. Figure 5
shows the expected site traffic distribution patterns. Figure 6 summarizes the estimated build -out site
traffic.

Roadway segment was evaluated based on ACHD level of service standards in accordance with Table 2
of the ACHD Policy Manual, Section 7106. The roadway segment level of service is based on the
maximum peak hour directional volume for different roadway functional classifications, number of
through lanes, and left -turn type. The minimum acceptable level of service is LOS D for collectors.
Local streets should be limited to a maximum of 2,000 vehicles per day, based on section 7207.3.1 of the
ACHD Policy Manual.
Intersection capacity analysis was performed using the Synchro 10 (Version 10.1.26), which utilizes the
2010 Highway Capacity Manual methodologies. All parameters used in the analysis were based on
existing data when available or Synchro default values, when not available. Level of service for
intersection is based on the average delay of vehicles traveling through the intersection. According to
ACHD policy, the minimum acceptable level of service is LOS D with a We ratio of 0.90 for the
intersection and 1.00 for a lane group.
2017 ExistingTraffic
Roadway Segment Level of Service
The study area roadway segments level of service were evaluated with 2017 existing traffic. Table 3

included in the appendix. Table 51 Table 6 and Table 7 summarize the measures of effectives (MOE)
firma the intersection capacity analysis. Based on traffic analysis results, both study area intersections are
currently operating at an acceptable level of service.

Roadway Segment Level of Service
The study area roadway segments level of service were evaluated with 2022 background traffic. Table 8
summarizes the results for the local roads. Table 9 summarizes the results for the collector road. All study
area roadway segments are expected to meet minimum operational thresholds with the existing lane
configuration. No roadway capacities improvements are needed to mitigate 2022 background traffic,

Mitigation
The westbound movement on Central Drive will operate at LOS F in the PM peak hour. This movement
already has two lanes. The north and south bound through movements have three lanes. There is not
touch that can be done to mitigate this intersection. The overall intersection operation is acceptable. The
LOS of the turn movements could be improved by adjusting the timing, but the overall delay at the
intersection would increase.
