a. Staff Comments/Recommendations: The report evaluated existing traffic conditions at three
Black Rock Coffee locations on similar arterial roadways during the AM peak period of coffee
shop trip generation to evaluate trip generation and queuing rates at the peak operation. The
analysis was warranted to determine the need for a northbound right-turn lane on Eagle Road
to accommodate potential queuing from the proposed Black Rock Coffee. Based on these
conditions, the report concluded that a maximum queue of 9 vehicles is recommended for use
as the design queue for the proposed shop on Eagle Road, as well as space for 6 additional
vehicles to queue back from the order kiosk. The analysis concluded that the queue storage
provided in the site plan is expected to be sufficient to support the maximum queue during
critical AM peak hour traffic. However, the report indicated that at the operational level, there
are circumstances that extend the service time for a customer or result in multiple vehicles
arriving at the order window that will require additional mitigation. Staff supports the findings in
the queuing analysis. Therefore, staff does not recommend that the applicant be required to
construct an additional northbound right-turn lane on Eagle Road or provide additional queuing
improvements as part of this application. However, the applicant should be required to
coordinate with the City of Meridian to address the operational strategies mentioned in the
analysis to mitigate the impacts of single vehicles with long services times and increase the
order efficiency when multiple vehicles arrive at the order kiosk.

2. Eagle Road
a. Existing Conditions: Eagle Road is improved with 5-travel lanes, vertical curb, gutter, 3-foot
wide concrete buffer between the curb and street edge of sidewalk and attached 10-foot wide
concrete sidewalk abutting the site. There is 96-feet of right-of-way for Eagle Road (47-feet from
centerline).
b. Policy:
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.
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 and Livable Streets Design Guide. 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 5-lane street section shall be 72-feet (back-of-curb to back-of-curb)within 96-
feet of right-of-way. This width typically accommodates two travel lanes in each direction, a
continuous center left-turn lane, and bike lanes on a minor arterial and a safety shoulder on a
principal arterial.
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.
Sidewalk Policy: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide to
be constructed on both sides of all arterial streets. A parkway strip at least 6-feet wide between
the back-of-curb and street edge of the sidewalk is required to provide increased safety and
protection of pedestrians. Consult the District's planter width policy if trees are to be placed
within the parkway strip. Sidewalks constructed next to the back-of-curb shall be a minimum of
7-feet wide.
Detached sidewalks are encouraged and should be parallel to the adjacent roadway.
Meandering sidewalks are discouraged.
A permanent right-of-way easement shall be provided if public sidewalks are placed outside of
the dedicated 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 sidewalk. Sidewalks shall either be located
wholly within the public right-of-way or wholly within an easement.
Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing
streets adjacent to a proposed development may be required. These improvements are to
correct deficiencies or replace deteriorated facilities. Included are sidewalk construction or
replacement; curb and gutter construction or replacement; replacement of unused driveways
with curb, gutter and sidewalk; installation or reconstruction of pedestrian ramps; pavement
repairs; signs; traffic control devices; and other similar items.
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
4 DRAFT Black Rock Coffee/ MER22-0059/ H-
2022-0019
features required through development. This segment of Eagle Road is designated in the MSM
as a Residential Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within
96-feet of right-of-way.
c. Applicant Proposal: The applicant is not proposing any street improvements to Eagle Road
abutting the site.
d. Staff Comments/Recommendations: Eagle Road was constructed with 5-lanes, vertical curb,
gutter, 3-foot wide concrete buffer, and 10-foot wide attached concrete sidewalk within 96-feet
of right-of-way as part of an ACHD project completed in 2022. Therefore, staff does not
recommend any additional road improvements or right-of-way dedication for Eagle Road
abutting the site.
Consistent with the District's Minor Improvements Policy, the applicant should be required to
replace any broken or deteriorated segments of curb, gutter, and sidewalk on Eagle Road
abutting the site.
3. Driveways
3.1 Eagle Road
a. Existing Conditions: There are two existing driveways from the site onto Eagle Road located
as follows (measured centerline to centerline):
• 36-foot wide paved curb-return type driveway located 33-feet north of the site's south
property line and 477-feet south of Eagle Road.
• 38-foot shared access paved curb-return type driveway that provides access to the site and
the adjacent parcel to the north. Of the 38-foot driveway, 12-feet of the driveway is onsite
and located approximately 273-feet south of Victory Road.
b. Policy:
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 45 MPH to align or offset a minimum of 380-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-
5 DRAFT Black Rock Coffee/ MER22-0059/ H-
2022-0019
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.
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.
c. Applicant's Proposal: The applicant is proposing to utilize the existing driveways from the site
onto Eagle Road to provide access to the site.
d. Staff Comments/Recommendations: The applicant's proposal to use the existing driveways
should be approved, as proposed. These driveways were approved as part of ACHD's action
on Shops at Victory subdivision, which final platted in 2016. These driveways may be restricted
at any time as traffic conditions warrant as determined by ACHD.
4. 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.
5. 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
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.

Introduction
The purpose of this memorandum is to evaluate the need for a northbound right-turn lane on Eagle Road
to accommodate potential vehicle gveving from a proposed Black Rock Coffee Shop to be located at
the soWtheast corner of Eagle Road and Victory Road in Meridian, Idaho.
The coffee shop will be constructed within an existing commercial development and is planned to be
approximately 1,925 square feet with a drive-through window and indoorseating.Two driveways on Eagle
Road serve as direct access to the coffee shop and two driveways on Victory Road provide additional
access through the parking lot of the adjacent Rite Aid.Figure 1 shows the preliminary site plan, including
access locations.

Black Rock Coffee Queuing Analysis
The Ada County Highway District (ACHD) has requested an analysis of the vehicle queuing for the site in
order to determine if the queuing from the drive-through windowwill be accommodated on-site or
whether a northbound right-turn lane at the southern driveway on Eagle Road might be considered for
additional queuing storage.
Data Collection
The findings from previously collected data at various coffee shops indicate that trip generation and queuing
for coffee shops can vary significantly based on the brand,operational strategies,and amount of traffic on
the adjacent roadways.Therefore,for the purpose of this analysis,data was collected at three established
Black Rock coffee shops on similar type arterials to estimate the projected trip generation and queuing
characteristics for the proposed site.The three sites include:
■ Chinden Boulevard& Linder Road:This shop is on the south side of Chinden Boulevard to the west of
Linder Road in a commercial development.The site includes a seating area and drive through.Based
on information provided by Black Rock Coffee,this shop is approximately 1,426 square feet.
■ Ustick Road:This shop is on the south side of Ustick Road to the east of Cloverdale Road.The site
includes a seating area and drive through.Based on information provided by Black Rock Coffee,this
shop is approximately 1,426 square feet.
■ Fairview Avenue:This shop is on the south side of Fairview Avenue to the east of Milwaukee Street and
west of Etheridge Lane.The site does not include any indoor seating.Based on information provided
by the Ada County assessor,this shop is approximately 620 square feet.
Based on a review of the data from past studies and trip generation information in the 1TE Trip Generation
Manual,the morning peak hour represents the critical weekday time period for traffic operations analysis.
Therefore,trip generation and queuing data was collected during the AM peak period of coffee shop trip
generation (approximately 7:00 AM to 9:00 AM) to represent peak operations analysis.
Trip Generation
While trip generation was not the focus of this study,the trip generation of the three sample Black Rock
Coffee shops was compared to the trip generation estimated for the proposed shop using the 1TE Trip
Generation Manual, 1 Iffi Edition.Table 1 shows the observed trip generation for the three example sites and
the average trip generation of the three sites during the AM peak hour.

Ustick Road 1,426 122 61 61 84.15
Observed Average Trip Rate(Shops with Seating Area) 79.24
As shown in Table 1,the trip rates per 1,000 square feet were relatively consistent for the two sites with
indoor seating,while the trip rate for the site on Fairview without indoor seating was much higher.Because
the majority of the trips to each site are drive-through trips,the results indicate that additional square
footage associated with the seating does not significantly impact the trip generation.Therefore,the

Black Rock Coffee Queuing Analysis
observed average trip rate was calculated based on the shops with indoor seating similar to the proposed
shop.
The trip generation for the proposed shop was estimated based on the average trip rate in Table 1
(excludes data from site with no indoor seating).The observed trip generation rate of Black Rock Coffee
Shops with indoor seating in the area was applied to the proposed 1,925 square foot coffee shop to
develop an expected trip generation during the AM peak hour.Table 2 shows the proposed coffee shop is
expected to generate approximately 152 trips in the AM peak hour(76 inbound 176 outbound).

The ITE Trip Generation Manual, 11th Edition estimate results in 1,030 daily trips with the critical AM peak hour
generating approximately 166 trip (85 inbound/81 outbound).Table 3 shows the estimated trip generation
based on the ITE Trip Generation Manual.

The estimated trip generation based on example Black Rock Coffee Shops was found to be approximately
8%lower than the trip generation estimate based on the ITE Trip Generation Manual in the weekday AM
peak hour used for the analysis.
Drive Through Queuing Analysis
Drive-Through queueing data from the three Black Rock Coffee Shops was used to estimate the 95th
percentile queue and maximum queue at the proposed coffee shop.Due to the drive-through trip
generation not being associated with the square footage of the shop,adjacent street traffic counts were
used to develop a queueing rate per 1,000 peak hour trips.Table 4 shows the 95th percentile queue and
maximum observed queue at each of the example locations.Also shown in Table 4 are traffic counts
obtained from ACHD.
As shown in Table 4,the maximum queues were relatively consistent between all three sites and there is no
strong correlation between size of the shop and queue lengths.There is also not a strong correlation
between the queue lengths and volumes on the adjacent arterial street,but the differences in adjacent
street volumes and queueing were minor between the shops.This indicates that adjacent street traffic
volume may be more correlated to queueing than square footage,but data from additional sites would
be required to determine the level of correlation of either indicator.

Based on the existing traffic counts on Eagle Road,year 2030 traffic volumes were estimated and used to
predict the 95th percentile queue and maximum queue for the proposed shop in 2030.Table 5 shows the
results.

Based on the results in Table 5,a projected 951h percentile queue of 8 vehicles is recommended and a
maximum queue of 9 vehicles is recommended for use as the design queue in for the new shop proposed
on Eagle Road.
Order Kiosk Queuing at Arrival
As part of the data collection,data was gathered on the queue back from the order kiosk at Chinden
Boulevard and Ustick Road shops.The Fairview Shop did not have an advanced order kiosk.The reason for
collecting arrival queue data at the order kiosk is to capture instances of multiple vehicles queue at the
order kiosk even though there may not be a queue between the order kiosk and the pick-up window.
Those observations found that the maximum queue that developed in back of the order kiosks was 6
vehicles with a 95th percentile queue of 5 vehicles.Therefore,it is recommended that the design also
account for 6 vehicles of queueing back from the order kiosk.
Proposed Site Plan Queuing Evaluation
Figure 2 illustrates the recommended design queue on the proposed site plan.The site plan includes a total
drive-through storage distance of approximately 210'which will accommodate approximately 8 vehicles
assuming an effective vehicle length of 25'.There is approximately 1 15'of drive-through storage from the
order kiosk which will accommodate approximately 4 vehicles.This indicates that the proposed drive-
through will accommodate the projected 95th percentile queue.But during a maximum queue event or a
time period where a group of vehicles arrive at the order Kiosk,one vehicle will queue in the parking lot
area.

Additionally,there is approximately 125'of distance between the drrue-through entry lane and the
southern driveways on Eagle Road which could accommodate another 6 vehicles before reaching Eagle
Road.
While stacking vehicles beyond the drive-through storage lane during the maximum queuing event will
have impacts to parking accessibility,the additional distance to Eagle Road provides a buffer to ensure
vehicle queues don't extend onto Eagle Road. There is also an additional 75'storage area to the north of
the drive thru lane that can accommodate 3 vehicles if drive-through customers decide to enter from one
of the other development access driveways.
Based on this analysis,the queue storage provided in the site plan is expected to be sufficient to support
the projected maximum queue P vehicles) during the critical AAA peak hour.Therefore,we do not
recommend a northbound right-turn lane on Eagle Road be installed for the purpose of addressing queue
spillback from the proposed Black Rock Coffee Shop.

Black Rock Coffee Queuing Analysis
Operational Observations
While the site plan is expected to accommodate the recommended queue storage for the drive-through,
on-site observations indicate that the drive-through queues may be influenced by the coffee shop service
time and operations.The two most common elements observed that resulted in increased queues were the
following:
Extended service time for a single customer order: There were observations in which the service time
for a vehicle arriving when no queue was present took over 6 minutes.During that time,a queue of 6-
7 vehicles can occur,thus reaching the maximum queue behind the single vehicle.There may be
options for customers with orders that require extended time to be directed out of pick-up window line
to park and wait for their order to be hand-delivered,such that they don't delay other vehicles
behind them.
z Multiple vehicles arriving at the order window: There were observations when 4-5 vehicles arrived
within a couple minutes and queued back from the order kiosk,while no vehicles were queued
between the order kiosk and the pickup window.Both the Chinden Boulevard shop and Ustick Road
shop utilized employees to go out and take orders manually to minimize the service time,but this was
observed to occur only after a significant queue had developed.The process of having a person take
orders seemed to reduce the service times and reduce queuing_Responding with an employee to
take orders quickly when multiple vehicles arrive could reduce maximum queues and we recommend
implementation of this practice at this proposed Black Rock Coffee Shop.
Summary
Based on an evaluation of the trip generation and queueing data from three existing Black Rock Coffee
shops in similar arterial locations,the maximum queue length for the proposed Eagle Road Black Rock
Coffee shop is projected to be approximately 9 vehicles during the weekday AM peak hour.The site plan
shows a drive through lane that can store approximately 8 vehicles.Additionally,there is available storage
for 6 additional vehicles between the southern driveway on Eagle Road and the drive-through lane.
Therefore,no on-site mitigation is recommended to accommodate queuing vehicles from the Black Rock
Coffee Shop,and a northbound right-tum lane on Eagle Road is not recommended to accommodate
potential queue spillback onto Eagle Road.
Even though site plan changes or adding a turn lone on Eagle Road are not required to accommodate
on-site queuing,we recommend that store management incorporate operational strategies to reduce the
impacts of a single vehicle with a long service time and increase order efficiency when multiple vehicles
arrive at the order kiosk.
We trust that the information provided herein adequately addresses the question from ACHD regarding the
need for a turn lane on Eagle Road to accommodate queueing from the Black Rock Coffee Shop.Please
contact us if you have any questions or need any additional information.
