D. Traffic Impact Study - Summary and Findings
1. Traffic Impact Study
Kimley-Horn & Associates prepared a traffic impact study (TIS) for the proposed coffee and quick
lubrication vehicle shop. An executive summary of the findings as presented by Kimley-Horn &
Associates can be found as Attachment A. ACHD has reviewed the submitted traffic impact study
for consistency with ACHD policies and practices and may have additional requirements beyond
what is noted in the TIS. Staff comments and recommendations on the submitted traffic impact
study can be found below.
a. Policy:
Mitigation Proposals: Mitigation recommendations shall be provided within the report. At a
minimum, for each roadway segment and intersection that does not meet the minimum
acceptable level of service planning threshold or v/c ratio, the report must discuss feasible
measures to avoid or reduce the impact to the system. To be considered adequate, measures
should be specific and feasible. Mitigation may also include:
• Revision to the Phasing Plan to coincide with the District's planning Capital Projects.
• Reducing the scope and/or scale of the project.
Alternative Mitigation Measures: 7106.7.3 states that if traditional mitigation measures such
as roadway widening and intersection improvements are infeasible as determined by ACHD,
the TIS may recommend alternative mitigation measures. Alternative mitigation measures shall
demonstrate that impacts from the project will be offset.
• If the impacted roadway segments and/or intersections are programmed as funded in
the Integrated Five Year Work Plan (IFYWP) or the Capital Improvements Plan (CIP);
no alternative mitigation is required.
• If the impacted roadway segments and/or intersections are not programmed in either
the IFYWP or the CIP; the applicant may (i) analyze the shoulder hour, defined as the
hour prior to after the determined peak hour within the two-hour peak period, (sometime
analyzed as hour before or after peak period) and (ii) provide a safety analysis to
determine alternative mitigation requirements.
o If the impacted roadway segments and intersections meet the minimum acceptable
level of service planning thresholds in the shoulder hour, the applicant may suggest
feasible alternative mitigation measures beyond improvements from District policy,
such as: off-site sidewalks, off-site bike facilities, connectivity, safety improvements,
etc. within 1.5 miles of the proposed development.
o If the shoulder hour planning thresholds are exceeded the applicant may request to
enter into a Development Agreement and pay into the Priority Corridor Fund an
amount determined by the ACHD to offset impacts from the project.
• Alternative Mitigation may also include:
o Revision to the Phasing Plan to coincide with the District's future Capital Projects.
o Reducing the scope and/or scale of the project.
Level of Service Planning Thresholds: District Policy 7205.3.1 states that Level of Service
Planning Thresholds have been established for principal arterials and minor arterials within
ACHD's Capital Improvement Plan and are also listed in section 7106. Unless otherwise
required to provide a Traffic Impact Study under section 7106, a proposed development with
site traffic less than 10% of the existing downstream roadway or intersection peak hour traffic
6 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
shall not be required to provide mitigation for a roadway or intersection that currently exceeds
the minimum acceptable level of service planning threshold or V/C ratio.
b. TIS Findings: Staff has reviewed the submitted traffic impact study (TIS). The TIS indicates
that the roadway segments and intersections in the study area are anticipated to operate at an
acceptable level of service, and that vehicles are unlikely to queue on Fairview Avenue while
waiting to access the site.
c. Staff Comments/Recommendations: Staff agrees with the findings and recommendations of
the traffic impact study and does not recommend any mitigation for this development.
7 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
E. Findings for Consideration
1. Fairview Avenue
a. Existing Conditions: Fairview Avenue is improved with 5-travel lanes, vertical curb, gutter,
and 5-foot-wide sidewalk. There is 104-feet of right-of-way for Fairview Avenue (54-feet from
centerline).
b. Applicant Proposal: The applicant is not proposing any additional improvements to Fairview
Avenue.
c. Staff Comments/Recommendations: The applicant's proposal meets District policy and
should be approved.
The applicant should be required to dedicate additional right of way to total 62-feet from
centerline.
The applicant should be required to repair or replace any deteriorated transportation facilities
abutting the site.
2. Driveways
2.1 Fairview Avenue
a. Existing Conditions: There is an existing 25-foot-wide shared driveway onto Fairview Avenue
located at the site's east property line. This driveway is shared with parcel directly east of the
site 12668 W Fairview (S1104438500).
b. Applicant's Proposal: The applicant is proposing to use the existing shared driveway to
access the site.
c. Staff Comments/Recommendations: The applicant's proposal does not meet District
driveway location or width policy; however, staff recommends allowing the driveway to be
located as proposed due to the fact the applicant's proposal maximizes the distance from the
driveway and the next intersection within the available site frontage and reduces the number of
driveways on Fairview Avenue by sharing a driveway with an adjacent business. However, the
applicant may want to consider still widening the driveway to between 30 and 36-feet to
accommodate anticipated volumes of traffic and to make it easier to enter and exit the site.
3. Other Access
Fairview Avenue is classified as a principal arterial roadway. Other than the access specifically
approved with this application, direct lot access is prohibited to this roadway and should be noted
on the final plat.
8 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
F. Policy
1. Federal Accessibility Design Guidelines and Standards
District policy 7203.1.1 states that developers shall follow the current version of the U.S. Access
Board's Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way(PROWAG), 36
CFR Part 1190, September 7, 2023; (Also see, https//www.access-board.gov/prowag and
https//www.access-board.gov/files/prowag/planning-and-design-for-alternatives.pdf for additional
information).
2. Minor Improvements
Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing
Highways adjacent to a proposed development may be required. These needed transportation
facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or
bike lane construction or replacement (with physical buffers if missing and needed); construction of
transitional sidewalk segments; crosswalk construction or replacement; curb and gutter
construction or replacement; repair, replacement or expansion of curb extensions; replacement of
unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation
features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle,
pedestrian and bicycle traffic control devices; and other similar items. The current version of
PROWAG will determine the applicable accessibility requirements for alterations and elements
added to existing streets. ACHD staff is responsible for identifying the minor improvements that
would be proportionate to the size and complexity of the development.
3. Livable Street Performance Measures
District policy 7203.8 states that ACHD has adopted performance measures (level of stress) for
evaluating the experience of bicyclists and pedestrians. ACHD seeks to create a transportation
network that serves all ages and abilities. Bike and pedestrian facilities built through development
should achieve a bike and pedestrian level of traffic stress 1 or 2, with no new bike lane below a
minimum of 5-feet.
4. Fairview Avenue
Arterial Roadway Policy: District Policy 7205.2.1 states that the developer is responsible for
improving all street frontages adjacent to the site regardless of whether or not access is taken to all
of the adjacent streets. Improvements shall include transitional segments in accordance with the
current version of PROWAG.
Master Street Map and Typology Policy: District Policy 7205.5 states that the design of
improvements for arterials shall be in accordance with District standards, including the Master
Street Map, Livable Streets Design Guide, and the most current ACHD Livable Streets Performance
Measures Plan as adopted by the ACHD Commission. The developer or engineer should contact
the District before starting any design.
Street Section and Right-of-Way Width Policy: District Policies 7205.2.1 & 7205.5.2 state that
the standard 7-lane street section shall be 81-feet (back-of-curb to back-of-curb). This width
typically accommodates three travel lanes in each direction, a continuous raised or landscaped
median with intermittent turn lanes, and curbs and gutters. A 7-lane road shall also include a
minimum 10-foot wide multi-use path outside the curb line on both sides with an 8-foot wide buffer
from back-of-curb. Other Level 3 bike facility treatments as defined in the ACHD Bike Master Plan
may be approved at the discretion of the ACHD Development Review Supervisor. The standard
right-of-way width for a 7-lane arterial is 124-feet.
If a landscaped median is included in any of these cross sections, the landscaping shall be
maintained by license agreement with the adjacent HOA, property owner, or by interagency
agreement with the corresponding land use jurisdiction.
9 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
At the discretion of Traffic Engineering staff, adjustments may be made to the street section,
including removal of the continuous center turn lanes or modification to lane widths, where no
driveways or intersections are present or to ensure adequate space for pathway and buffers.
Right-of-Way Dedication: District Policy 7205.2 states that The District will provide compensation
for additional right-of-way dedicated beyond the existing right-of-way along arterials listed as impact
fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the
Impact Fee Service Area.
No compensation will be provided for right-of-way on an arterial that is not listed as impact fee
eligible in the Capital Improvements Plan.
The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor
for future capacity improvements, as provided in Section 7300.
Pedestrian Facilities: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide are
required on both sides of all arterial streets. A parkway strip at least 8-feet wide between the back-
of-curb and street edge of the sidewalk is required to provide increased safety and protection of
pedestrians. Alternatively, on roadways identified for improvement in the Capital Improvement Plan,
a minimum 10-foot wide multi-use path may be required. The path shall be placed in accordance
with planned buildout in the Master Street Map with a minimum 8-foot wide planter strip as
measured to the closest edge of the path. Street trees are encouraged between the pedestrian
facility and the roadway when irrigation and maintenance will occur by the adjacent property owner
or HOA through an approved license agreement. Consult the District's planter width policy if trees
are to be placed within the parkway strip. In some instances, to match existing conditions, a
minimum 7-foot wide sidewalk may be constructed next to the back-of-curb. ACHD Development
Review staff will be responsible for determining the required facility. Vertical hardscape alternatives
to street trees may be considered in the buffer space when street trees are not practicable.
Detached sidewalks and multi-use paths are encouraged and should be parallel to the adjacent
roadway. Pedestrian facilities will only be allowed to deviate from a straight line parallel to the
roadway when authorized by Development Review staff to accommodate site specific conditions
(i.e., street trees, utilities, etc.).
Appropriate easements shall be provided if public pedestrian facilities are placed out of the right-of-
way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind
the back edge of the pedestrian facility. Pedestrian facilities shall either be located wholly within the
public right-of-way or wholly within an easement.
Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each
pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable
warning surface in accordance with the current version of PROWAG.
Frontage Improvements Policy: District Policy 7205.2.1 states that the developer shall widen the
pavement to a minimum of 17-feet from centerline plus a 3-foot wide gravel shoulder adjacent to
the entire site. Curb, gutter and additional pavement widening may be required (See Section
7205.5.5).
ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM)
guide the right-of-way acquisition, arterial street requirements, and specific roadway features
required through development. This segment of Fairview Avenue is designated in the MSM as a
Mobility Arterial with 7-lanes and on-street bike lanes, a 91-foot street section within 124-feet of
right-of-way.
5. Driveways
5.1 Fairview Avenue
10 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
Access Points Policy: District Policy 7205.4.1 states that all access points associated with
development applications shall be determined in accordance with the policies in this section and
Section 7202. Access points shall be reviewed only for a development application that is being
considered by the lead land use agency. Approved access points may be relocated and/or
restricted in the future if the land use intensifies, changes, or the property redevelops.
Access Policy: District policy 7205.4.7 states that direct access to principal arterials is typically
prohibited. If a property has frontage on more than one street, access shall be taken from the street
having the lesser functional classification. If it is necessary to take access to the higher classified
street due to a lack of frontage, the minimum allowable spacing shall be based on Table 1 b under
District policy 7205.4.7, unless a waiver for the access point has been approved by the District
Commission. Driveways, when approved on a principal arterial shall operate as a right-in/right-out
only, and the District will require the construction of a raised median to restrict the left turning
movements.
Driveway Location Policy: District policy 7205.4.7 requires driveways located on principal arterial
roadways to be located a minimum of 355-feet from the nearest intersection for a right-in/right-out
only driveway. Full-access driveways are not allowed on principal arterial roadways.
Successive Driveways: District policy 7205.4.7 Table 1 b, requires driveways located on principal
arterial roadways with a speed limit of 40 MPH to align or offset a minimum of 330-feet from any
existing or proposed driveway.
Driveway Width Policy: District policy 7205.4.8 restricts high-volume driveways (100 VTD or
more)to a maximum width of 36-feet and low-volume driveways (less than 100 VTD)to a maximum
width of 30-feet. Curb return type driveways with 30-foot radii will be required for high-volume
driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for
low-volume driveways with less than 100 VTD.
Driveway Paving Policy: Graveled driveways abutting public streets create maintenance
problems due to gravel being tracked onto the roadway. In accordance with District policy,
7205.4.8, the applicant should be required to pave the driveway its full width and at least 30-feet
into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance
with Table 2 under District Policy 7205.4.8.
Temporary Access Policy: District Policy 7202.4.2 identifies a temporary access as that which
"is permitted for use until appropriate alternative access becomes available". Temporary access
may be granted through a development agreement or similar method, and the developer shall be
responsible for providing a financial guarantee for the future closure of the driveway.
Cross Access Easements/Shared Access Policy: District Policy 7202.4.1 states that cross
access utilizes a single vehicular connection that serves two or more adjoining lots or parcels so
that the driver does not need to re-enter the public street system.
6. Tree Planters
Tree Planter Policy: Tree Planter Policy: The District's Tree Planter Policy prohibits all trees in
planters less than 8-feet in width without the installation of root barriers. Class II trees may be
allowed in planters with a minimum width of 8-feet, and Class I and Class III trees may be allowed
in planters with a minimum width of 10-feet.
7. Landscaping
Landscaping Policy: A license agreement is required for all landscaping proposed within ACHD
right-of-way or easement areas. Trees shall be located no closer than 10-feet from all public storm
drain facilities. Landscaping should be designed to eliminate site obstructions in the vision triangle
at intersections. District Policy 5104.3.1 requires a 40-foot vision triangle and a 3-foot height
restriction on all landscaping located at an uncontrolled intersection and a 50-foot offset from stop
11 Fairview Drive Thru Coffee/MER24-0065/
H-2024-0049
signs. Landscape plans are required with the submittal of civil plans and must meet all District
requirements prior to signature of the final plat and/or approval of the civil plans.
8. Pathway Crossings: United States Access Board R304.5.1.2 Shared Use Paths. In shared use
paths, the width of curb ramps runs and blended transitions shall be equal to the width of the shared
use path.
AASHTO's Guidelines for the Development of Bicycle Facilities 5.3.5 Other Intersection
Treatments: The opening of a shared use path at the roadway should be at least the same width
as the shared use path itself. If a curb ramp is provided, the ramp should be the full width of the
path, not including any flared sides if utilized. . . . Detectable warnings should be placed across the
full width of the ramp.
FHWA's "Designing Sidewalks and Trails for Access" (1999) reflected common ADA-related
concepts: Chapter 6, Page 16-6: The width of the ramp should be at least as wide as the average
width of the trail to improve safety for users who will be traveling at various speeds. In addition, the
overall width of the trail should be increased, so the curb ramp can be slightly offset to the side.
The increased width reduces conflict at the intersection by providing more space for users at the
bottom of the ramp.

Trip Generation
The Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition, was used to obtain
peak hour weekday AM trip generation equations or rates and inbound-outbound percentages for quick
lubrication oil changing facility (ITE Code 941) which were then used to estimate the number of AM peak
hour trips that can be attributed to the proposed development. The process outlined in the ITE Trip
Generation Handbook, 3rd Edition, was used to determine whether average rates or equations should be
used in calculating each land use's trip generation.
Kimley-Horn collected drive-through vehicle queue information at three Human Bean coffee shop locations
in Meridian, ID. Peak period (Weekday AM lam—9am) drive-through vehicle queuing totals were collected
at the following locations:
• • 1100 W. Idaho Street, Suite 210, Boise, 1 1: • ::
Kimley>>> Horn Page 3
• 1635 N Meridian Rd, Meridian, ID, June 2024 (491 sq. ft.)
• 2385 W Nelis Dr, Meridian, ID, June 2024 (480 sq. ft.)
• 2480 E Gala St, Meridian, ID, June 2024 (480 sq. ft)
Table 1 summarizes the trip generation of observed at the drive-throughs for the peak weekday AM hours.
Drive-through queue data collected is provided in Attachment B.

Observed Average Trip Rate Per 1,000 GSF 128.2
The trips to each site primarily involve drive-through visits and Table 1 shows that trip rates vary for each
site even though they are similar GSF. These results show that GSF does not have significant impact on
trip generation.
To estimate trip generation for the proposed Fairview coffee shop, the average trip rate from Table 1 was
used. The observed average trip generation rate from a similar Human Bean Coffee shop was applied to
the proposed 650 square feet stand to forecast expected trip generation during the AM peak hour. Table 2
shows the estimated trip generation based on the observed average rate.

The ITE Trip Generation Manual, 11th Edition estimates the coffee shop will generate 179 daily trips with
the AM peak hour generating approximately 40 total trips, with 20 trips entering and 20 trips exiting.
Additionally, it estimates the quick lubrication oil changing facility to generate 90 total daily trips with the AM
peak hour generating approximately eight total trips, with six trips entering and two trips exiting. Table 3
shows the estimated trip generations from the ITE Trip Generation Manual.

The estimated number of trips generated from the sampled Human Bean locations were found to be
around 52% greater than the trip generation estimated from the ITE Trip Generation Manual for the
weekday AM peak hour.
Drive-Through Queueing Data
The proposed Human Bean Coffee shop will have a single drive-through entrance leading to a service lane
that extends from the entrance to the pick-up window and continues along the north side of the building,
and back along the east side of the building to the south site access. The pick-up window is located on the
west side of the building, providing a single lane for vehicles to queue.
The drive-through lane offers approximately 80 feet of storage from the pickup window to the order station.
An additional 300 feet of storage is available between the order station and the driveway off Fairview
Avenue. This configuration can accommodate approximately 15 vehicles, assuming each vehicle requires
25 feet of space. In addition, the parking at the building site has capacity to hold an additional 18 vehicles.
The queuing data from sample Human Bean location's drive-throughs was used to estimate the 95th
percentile queue and maximum queue at the proposed coffee stand. Because drive-through trip generation
is not directly tied to building square footage, traffic counts from adjacent arterial streets gathered from
ACHD online traffic counts for the locations below were used to estimate a queuing rate.
• Meridian Road, South of Fairview Avenue—Collected on 3/20/2019
• Ten Mile Road, South of McMillan Road—Collected on 9/15/2021 (used for Nelis location)
• Overland Road, West of Locust Grove—Collected on 10/5/2021 (used for Gala location)
• Fairview Avenue, East of Eagle Road—Collected on 7/27/2022
The counts were grown to 2024 travel volumes using growth rates provided by COMPASS. It should be
noted that the COMPASS model outputs show no growth along the Ten Mile Road and Overland Road
segments that the Nelis Drive and Gala Street locations have frontage on. Attachment C provides
COMPASS growth rates. This methodology mirrors the approach used in trip generation data collection
and rate calculation, shown in Table 4.

Based on the volumes collected from 2022 ACHD traffic counts for Fairview Avenue and grown to 2024
traffic volumes, the estimated 95th percentile and maximum queues at the proposed coffee stand are four
and six cars, respectively. Table 5 shows the estimated queue results.

It is recommended to use the estimated 95th percentile queue of four vehicles and a maximum queue of six
vehicles as the design parameters for the new coffee stand on Fairview Ave.
Proposed Site Plan Queuing Evaluation
The site plan specifies a total drive-through storage of about 80 feet, designed to accommodate up to three
vehicles, assuming each vehicle is approximately 25 feet long.Additionally, there is approximately 300 feet
of drive-through storage from the order stand to the driveway on Fairview Avenue. This configuration
ensures that the proposed drive-through can easily handle the estimated 95th percentile and maximum
queue,even during peak times or instances when multiple vehicles arrive simultaneously at the order stand.
Figure 2 shows the queue storage on the proposed site plan.

Figure 2 —Queue Storage
While extended vehicle queuing beyond the drive-through storage during maximum queuing events may
impact parking accessibility and entrance to the quick lubrication oil changing facility, it's likely that these
occurrences will be rare as popular time for the coffee shop do not normally align with that of a lube
changing facility. The available storage and configuration of the proposed site should support the estimated
maximum queue of six vehicles during the AM peak hour and access to the lube and parking facilities during
these times.
Conclusions
Based on the trip generation and queuing data from comparable Human Bean Coffee shops, it is
estimated that the maximum queue length for the proposed Fairview Avenue location during the AM peak
hour will be approximately six vehicles. The site plan features a drive-through lane designed to
accommodate about three vehicles, along with additional storage for up to approximately 12 vehicles,
which exceeds the anticipated maximum queue.
The evaluation indicates that queue spill back onto Fairview Avenue is unlikely. Therefore, no on-site
mitigation measures are recommended to manage queuing vehicles. Additionally, there is no
recommendation for a westbound right-turn lane to address potential queue spillback onto Fairview Ave.

It is recommended that store management implement operational strategies to mitigate the impact of
individual vehicles with longer service times and to enhance order efficiency during peak periods when
multiple vehicles queue.
