A. Findings of Fact
1. Description of Application: The applicant is requesting annexation of 71.88 acres of land with an
R-15 zoning district; and conditional use permit for a 259,000 square-foot private education school
for pre-K through 12th grade on 48.48 acres of land in the R-15 zoning district. The proposed rezone
to R-15 is consistent with the City of Meridian's Future Land Use Map, which designates this parcel
as Medium Density Residential.
2. Description of Adjacent Surrounding Area:
Direction Land Use Zoning
North Rural Urban Transitional Ada Count RUT Ada Count
South Rural Urban Transitional (Ada County), RUT (Ada County),
Medium Density Residential R-8
East Rural Urban Transitional Ada Count RUT Ada Count
West Rural Urban Transitional (Ada County) RUT (Ada County)
3. Site History: ACHD has not previously reviewed this site for a development application.
4. Transit: Transit services are not available to serve this site.
5. 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.
1 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
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.
6. New Center Lane Miles: The proposed development includes 0.76 centerline miles of new public
road.
7. Impact Fees: There will be an impact fee that is assessed and due prior to issuance of any building
permits. The assessed impact fee will be based on the impact fee ordinance that is in effect at that
time. The impact fee assessment will not be released until the civil plans are approved by ACHD.
8. Capital Improvements Plan (CIP)/ Integrated Five Year Work Plan (IFYWP):

9. Roadways to Bikeways Master Plan: ACHD's Roadways to Bikeways Master Plan (BMP) was
adopted by the ACHD Commission in May 2009 and updated in 2018. The plan seeks to implement
the Planned Bicycle Network to support bicycling as a viable transportation option for Ada County
residents with a wide range of ages and abilities, maintain bicycle routes in a state of good repair
in order to ensure they are consistently available for use, promote awareness of existing bicycle
routes and features and support encouragement programs and to facilitate coordination and
cooperation among local jurisdictions in implementing the Roadways to Bikeways Plan findings.
The BMP identifies McMillan Road as Level 2 facilities that will be constructed as part of a future
ACHD project. The BMP also identifies level 1 facilities on the Owyhee Storm Avenue. The applicant
2 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
will construct Owyhee Storm Avenue consistent with the MSM and the Roadways to Bikeways
Master plan.
B. Traffic Findings for Consideration
1. Trip Generation: This development is estimated to generate 4,132 additional vehicle trips per day;
1,196 additional vehicle trips per hour in the school PM peak hour, based on the traffic impact study.
2. Traffic Impact Study
Kittelson & Associates, Inc. prepared a traffic impact study and School Site Checklist for the
proposed Cole Valley Christian School. An executive summary of the findings as presented by
Kittelson & Associates, Inc can be found below as Attachment 3. The executive summary is
not the opinion of ACHD staff. 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 summary. ACHD Staff comments on the submitted traffic impact study can be found

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.
3 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
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 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 such as: sidewalks, 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 7206.4.1 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
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) and generally agree
with the findings and recommendations. The TIS provided two scenarios, before and after the
SH-16 extension. ITD anticipated that SH-16 Phase 2 from US 20/26 to 1-84 to be operational
by 2025; as such, the following discussion will only consider after SH-16 improvements.
Additionally, the TIS included a school site checklist confirming with Idaho Code 67-6519(3),
which is included in Attachment 4. Beyond the TIS findings and improvements required to
meet District operational thresholds, on-site pedestrian facilities, including pedestrian pathways,
crosswalks, and signing/striping to delineate vehicular from pedestrian traffic, are the primary
findings of recommendation from the school site checklist.
The study found the following intersection deficiencies described below, coupled with the
percentage site traffic contributions relative to the school PM peak hour total traffic, followed
with their recommendations for improvements.
Intersections:
• Black Cat Road / US 20/26 (3.4%)
o The northbound shared through/right-turn lane exceeds ACHD's Acceptable Level
of Service Planning Thresholds in the AM peak hour under 2025 background
conditions. Under 2025 total conditions, this lane group is anticipated to exceed
ACHD's Acceptable Level of Service Planning Thresholds in both the AM and school
PM peak hours.
4 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
o This intersection was recently reconstructed to a 5 X 6 X 3 signalized intersection in
2021 in conjunction with the US 20/26 widening; the TIS recommended no
widening/capacity improvements under 2025 background or total traffic conditions
beyond review of the current signal timing on the US 20/26 corridor.
o Additional site generated traffic is anticipated to be less than 10% during the school
PM peak hour, therefore no mitigation on ACHD approaches is required consistent
with ACHD policy 7206.4.1.
o According to the TIS, the intersection exceeds ITD's 0.90 lane group v/c ratio
operational threshold under 2021 existing conditions.
■ ITD did not provide any comments regarding this TIS.
• Star Road / McMillan Road (27.9%)
o The southbound left-turn lane exceeds ACHD's Acceptable Level of Service
Planning Thresholds in the AM peak hour under 2025 total conditions. To mitigate
this deficiency, the TIS recommends signal timing adjustments.
■ The intersection is listed in the CIP to be reconstructed/widened as a multilane
roundabout with 2-lanes on the north and south legs and 1-lane on the east and
west legs between 2031 and 2035. The TIS did not analyze this intersection with
a lane configuration consistent with or phaseable to the improvements
programmed in the CIP.
■ Additional mitigation was considered for this intersection, which includes
southbound dual left-turn lanes, downstream widening, and a westbound right-
turn lane. This mitigation is beyond the 3-lane CIP widening on McMillan Road
and was not further considered; signal timing adjustments were found as an
acceptable mitigation.
o Based on analysis included in the TIS, the southbound left-turn lane is expected to
exceed ACHD thresholds by year 2025, when the site generates 1,369 AM peak-
hour trips or has 1,350-students in attendance.
• Ersatz Road / McMillan Road (52.5%)
o This intersection is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the AM and school PM peak hours under 2025 total traffic
conditions. To mitigate this deficiency, the TIS recommends conversion to a 3x3
signalized intersection with an additional westbound right-turn lane under 2025 total
traffic conditions. Staff does not recommend the installation of a signal in this
location, due to the spacing of this intersection.
o The study also included an analysis of this intersection as right-in/right-out only and
found that if the intersection is restricted to right-in and right-out(RIRO) movements,
the intersection is expected to meet ACHD operational thresholds; however, all site-
generated left-turning traffic would shift to Owyhee Storm Avenue and would result
in that intersection operating at capacity during the school AM peak hour.
o Based on the analysis, the southbound left-turn lane is expected to exceed ACHD
thresholds by year 2025, when the site is anticipated to have generated 1,186 AM
peak hour trips or has 1,200-students in attendance.
• Black Cat Road / McMillan Road (24.4%)
o The eastbound and southbound approaches exceed ACHD's Acceptable Level of
Service Planning Thresholds in the AM peak hour under existing conditions. To
mitigate this deficiency, the study recommends TIS proposes conversion to either a
single-lane roundabout or a 3x3 signalized intersection under 2021, 2025
background, and 2025 total traffic conditions.
5 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
■ This intersection is programmed as a funded improvement in the IFYWP to be
reconstructed as a multilane roundabout with a right-of-way acquisition year of
2023 and a construction year of 2024. Therefore, no mitigation is required
consistent with ACHD policy 7106.7.3.
• Ten Mile Road / McMillan Road (9.3%)
o The intersection exceeds ACHD's Acceptable Level of Service Planning Thresholds
in the school PM peak hour under 2025 total traffic conditions but operates
acceptably during the traditional AM and PM peak hours. Additional site generated
traffic is anticipated to be less than 10% during the school PM peak hour, therefore
no mitigation is required consistent with ACHD policy 7206.4.1.
Roadway Segment:
• McMillan Road — Star Road to Owyhee Storm Avenue (39.0%)
o The roadway segment is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the AM peak hour under 2025 total traffic conditions.

that the roadway segment operates acceptably during the AM and PM school
shoulder hours, but exceeds ACHD's standards during the traditional PM peak hour.
■ This segment of McMillan Road is listed in the CIP as a funded improvement to
be widened to 3 lanes. Additionally, no public roadways connect to McMillan
Road in this section. As such, and the segment meeting shoulder hour LOS
planning thresholds, staff does not recommend that the applicant be required to
improve this off-site roadway segment with this development application.
• McMillan Road — Owyhee Storm Avenue to McDermott Road (51.0%)
o The roadway segment is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the AM school PM peak hours under 2025 total traffic
conditions.
o This segment is listed in the CIP as a funded improvement to be widened to a 3-lane
section between 2036-2040.
o Consistent with District Policy a shoulder hour analysis was conducted and found
that the roadway segment operates acceptably during the AM and PM school
shoulder hours, but exceeds ACHD's standards during the traditional PM peak hour.
■ This segment of McMillan Road is listed in the CIP as a funded improvement to
be widened to 3 lanes. Additionally, all public roadways on McMillan Road in this
section have existing left-turn lanes. As such, and the segment meeting shoulder
hour LOS planning thresholds, staff does not recommend that the applicant be
required to improve this off-site roadway segment with this development
application.
• McMillan Road — McDermott Road to Black Cat Road (44.7%)
o The roadway segment is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the AM and school PM peak hours under 2025 total traffic
conditions.
o This segment is listed in the CIP as a funded improvement to be widened to a 3-lane
section between 2036-2040.
o Consistent with District Policy, a shoulder hour analysis was conducted and found
that this segment of McMillan Road is anticipated to operate acceptably during the
6 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
AM and PM shoulder hours. Additionally, this roadway segment is listed in the CIP
as a funded improvement to be widened to a 3-lane section between 2036-2040.
Therefore, consistent with ACHD policy 7106.7.3, no mitigation is required.
• McMillan Road — Black Cat Road to Ten Mile Road (17.3%)
o The roadway segment is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the school PM peak hour under existing traffic conditions and
in the AM peak hour under 2025 total traffic conditions.
o This segment is listed in the CIP as a funded improvement to be widened to a 3-lane
section between 2031-2035.
o Consistent with District Policy, a shoulder hour analysis was conducted and found
that this segment of McMillan Road operates acceptably during the AM and PM
school shoulder hours, but exceeds ACHD's standards during the traditional PM
peak hour.
o This roadway segment is listed in the CIP as a funded improvement to be widened
to a 3-lane section between 2031-2035. Therefore, consistent with ACHD policy
7106.7.3, no mitigation is required.
• Owyhee Storm Avenue — McMillan Road to Ustick Road (39.0%)
o The roadway segment is anticipated to exceed ACHD's Acceptable Level of Service
Planning Thresholds in the school PM peak under 2025 background traffic conditions
and in the school AM and PM peak hours 2025 total traffic conditions.
o This roadway is identified as a 2-lane residential collector in the MSM.
o Consistent with District Policy, a shoulder hour analysis was conducted and found
that this segment meets ACHD's thresholds in the shoulder hour during the school
AM and PM peak hours.
■ Turn lanes are already constructed on this segment of Owyhee Storm Avenue at
major driveways and roadways, and this roadway will be improved with future
development applications along the west side of the roadway. Additionally, this
roadway segment meets shoulder hour LOS planning thresholds; therefore, no
mitigation should be required on this segment of roadway.
Turn Lanes:
The applicant's TIS included turn lane warrant analysis at all off-site and collector access study
area intersections. The following turn lanes are warranted based on the findings in the TIS:
• Site Access A/ Owyhee Storm Avenue
o Northbound right-turn lane
• Site Access C / Ersatz Road
o Northbound left-turn lane
• Owyhee Storm Avenue / McMillan Road
o Westbound right-turn lane
• Ersatz Road / McMillan Road
o Westbound right-turn lane
c. Staff Comments/Recommendations: Based on the findings of the TIS, a northbound right-
turn lane will be required with the construction of the Site Access A and Owyhee Storm Avenue
intersection. A northbound left-turn lane will be required with the construction of the Site Access
C and Ersatz Road intersection.
The following intersection improvements are required with construction of Cole Valley Christian
Schools:
7 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011

C. Findings for Consideration
1. School Site Checklist
As noted above, the applicant's traffic impact study included a 22-item checklist confirming with
Idaho Code 67-6519(3), which is included in Attachment 4.
1.1 School Bus Plan
a. Staff Comments/Recommendations: The checklist's school bus plan discussion states no
school bus or shuttle service is anticipated. If school bus or shuttle service is incorporated after
opening, site circulation revisions will be required as the site plan does not include on-site
parking for buses/shuttles, nor does it include a dedicated approach off the collector roadways.
8 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
1.2 Pick-Up/Drop-Off Areas and Traffic Circulation
a. Staff Comments/Recommendations: The checklist's internal traffic circulation route notes two
pick-up/drop-off loops, one connecting to Owyhee Storm Avenue and the other to Ersatz Road.
Internal traffic circulation is anticipated to take place around the parking areas, with two
counterclockwise pick-up/drop-off patterns. The exhibit below is an excerpt from the TIS which
outlines in blue the planned counterclockwise vehicular pick-up/drop-off circulation patterns for
students to access the main school facility without needing to cross the parking areas. Upon
departure from the site, vehicles could continue east or west on McMillan Road, or to the south
on Owyhee Storm Avenue.
Some student drivers are expected as the proposed school includes a middle and high school.
To reduce student-parent vehicle conflicts within the circulation area, staff recommends a
staggered start time between grades 9-12 and grades pre-K to 8.

- ----------------------- -
1.3 Pedestrian Plan
a. Staff Comments/Recommendations: The checklist's pedestrian plan did not recommend any
signage or improvements to accommodate pedestrians or schoolchildren crossings, due to the
assumption that"a limited number of students may walk to the campus from the new residential
developments to the south." Additionally, no off-site crossing guards will be provided unless
determined to be needed with future residential developments within the vicinity of the site.
Thus, the supermajority of transportation for this school will be parental pick-up/drop-off.
As part of the findings and conditions of approval mentioned below, the applicant will be required
to construct sidewalk along the site frontages on Owyhee Storm Avenue Ersatz Road, and
McMillan Road. Schoolchildren crossing McMillan Road to access the site will require signalized
crosswalk utilization at the Owyhee Storm Avenue and McMillan Road intersection, barring any
additional crosswalks on McMillan Road between Owyhee Storm Avenue and Black Cat Road.
9 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
1.4 Signage, Striping, and School Zoning
a. Staff Comments/Recommendations: The checklist's striping and signing modification plan
recommends the following:
• Signing and striping of internal crosswalk locations
• Delineation of pedestrian walkways through the parking lots
• On-site signing and pavement markings for the parent drop-off/pick-up identifying
circulation direction, and curb loading area.
No specific signage is recommended for schoolchildren crossings, due to the assumption that
"a limited number of students may walk to the campus from the new residential developments
to the south." Thus, the supermajority of transportation for this school will be parental pick-
up/drop-off. Additionally, school zone, flashing beacons, HAWKs or RRFBs were not
recommended in the applicant's TIS or IC-67 checklist. The TIS notes the existing locations of
Cole Valley Christian School elementary campus does not have school zone designation on
Ustick Road or Maple Grove Road due to the low pedestrian and cycling traffic from students.
The site plan provided showed no striping plans for internal crosswalks or pedestrian walkways
through the parking lots. No pavement pedestrian walkway is readily identifiable, as all
pavement north of the collector accesses into the school are parking stalls or drive aisles.
If ACHD determines that signage, pavement markings, or any other safety improvements are
necessary for the school during the plan review process, than the applicant will be responsible
for design and installation of those items, regardless of what is recommended in the traffic
impact study.
The Cole Valley Christian School or any other future occupant should be responsible for all
costs associated with the design, hardware, and construction of any pedestrian facilities needed
to accommodate future pedestrian needs of the school. This includes flashing beacons,
crosswalk striping and signage, and HAWK signals or RRFBs.
2. State Highway SH-16
SH-16 is under the jurisdiction of the Idaho Transportation Department (ITD). The applicant, City
of Meridian, and ITD should work together to determine if additional right-of-way or improvements
are necessary on SH-16.
Staff Comments/Recommendations: ITD did not provide any comments on the traffic impact
study or the development application. However, the applicant has been in contact with ITD
regarding the SH-16 extension project and ITD's plans to construct a local access road, Ersatz
Road, along the site's east property line located '/4 mile west of SH-16. The applicant, the City of
Meridian, and ITD should work together to determine if any additional right-of-way will be necessary
to accommodate the SH-16 extension project or the construction of the local access road, Ersatz
Road.

3. Owyhee Storm Avenue & McMillan Road Intersection
a. Existing Conditions: The Owyhee Storm Avenue/McMillan Road intersection is a signalized
3x2/3 intersection with left-turn lanes on the south and east legs.
b. Applicant Proposal: The applicant is proposing to reconstruct/widen the signalized intersection
as a 4/3x3 intersection creating the 4t' leg (north) with left-turn lanes on all approaches and a
dedicated westbound right-turn lane, and a downstream auxiliary through lane west of the
intersection.

c. Staff Comments/Recommendations: The applicant's proposal to modify the existing
signalized intersection to add the north leg with left-turn lanes on all approaches and a
westbound right-turn lane meets District policy and should be approved, as proposed. The
applicant's proposal to construct a downstream auxiliary through lane west of the intersection
does not meet District policy and exceeds McMillan Road's MSM lane configuration of 3-lanes
and should not be approved, as proposed.
To accommodate this improvement and to provide access to the proposed school, the applicant
has indicated that they have entered into an agreement with the owner of the property north of
the Owyhee Storm Avenue/McMillan Road intersection to construct the north leg of the
intersection between the site and McMillan Road. The applicant should coordinate with the
owner of the off-site property to fully construct Owyhee Storm Avenue with 3-lanes at the
intersection (one northbound receiving lane, one southbound left-turn lane, and one southbound
shared through/right-turn lane).
Additionally, the applicant will need to obtain plan approval and enter into a signal agreement
with ACHD for the improvements to the intersection. The signal agreement should include
requirements that the intersection be designed as a 3 X 3/4 intersection with 12-foot wide travel
lanes: one receiving lane and one dedicated left-turn lane on all approaches, one thru/right lane
on the northbound, southbound, and eastbound approaches, and one through lane and one
dedicated right-turn lane on the westbound approach; that the applicant is responsible for all
costs associated with the hardware, design, and installation of the signal improvements, and
that improvements are not eligible for reimbursement by ACHD.
12 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
In order to ensure the Owyhee Storm Avenue/McMillan Road intersection will be improved when
warranted, the following items must be in place prior to plans acceptance:
• Signal Agreement
• Full design and approved plans for the intersection
• Right-of-way dedication
The construction of the signal modifications and the north leg of the intersection should be
completed prior to occupancy of the school in the fall of 2025.
4. Ersatz Road/Glassford Avenue & McMillan Road Intersection
a. Existing Conditions: Ersatz Road is not yet constructed abutting the site.
Glassford Avenue is located 125-feet east of the site's east property line and is located on the
south side of McMillan Road across from the site. There is currently a center left turn lane on
McMillan Road at Glassford Avenue.
b. Applicant Proposal: The applicant is proposing to modify ITD's planned construction of Ersatz
Road as a 2-lane rural roadway at its intersection with McMillian Road and to construct the north
leg of the intersection (Ersatz Road) as a 3-lane roadway with 12-foot wide travel lanes; one
receiving lane, one center turn lane, and one shared through/right-turn lane, aligning with
Glassford Avenue to the south.
c. Staff Comments/Recommendations: As noted above, ITD is in the process of acquiring right-
of-way abutting the site's east property line to construct a local access road as part of the SH-
16 extension project. The applicant has indicated that ITD is in discussions with the owner of
the property east of the site to acquire land to be used as right-of-way for the construction of the
north leg of the Ersatz Road & McMillan Road intersection. Additional land will be needed from
this property owner to ensure that Ersatz Road will align with Glassford Avenue on the south
side of McMillan Road across from the site. At this time, ITD has not yet acquired the right-of-
way to accommodate the construction of Ersatz Road. As such, 3 different scenarios should
be considered for this intersection.
• If right-of-way is not acquired for Ersatz Road to align with Glassford Avenue south of
McMillan Road, Ersatz Road will be required to offset a minimum of 80-feet of Glassford
Avenue, measured centerline to centerline.The Ersatz Road/McMillan Road intersection
will be fully restricted to right-in/right-out movements only with the installation of candles
to extend 75-feet west of Ersatz Road and 75-feet east of Glassford Avenue, also
restricting Glassford Avenue to right-in/right-out movements.
• If Ersatz Road is not constructed school access would only be provided via Owyhee
Storm Avenue. This will result in unfavorable operations of the Owyhee Storm Avenue
& McMillan Road intersection; as such, the school attending capacity will need to be
limited for adequate intersection operations and queuing until Ersatz Road is
constructed and access is provided to Cole Valley Christian Schools.
• If ITD is able to acquire the right-of-way necessary for Ersatz Road to be constructed in
alignment with Glassford Avenue, the intersection should be constructed as a two-way
stop-controlled intersection with movement restrictions of right-in/right-out/left-in only.
This portion of Ersatz Road will operate as an off-site street between the applicant's site and
McMillan Road until deeded as public right-of-way, as shown below. As part of this project, the
applicant should coordinate with ITD and the owner of the off-site property east of the site to
fully construct Ersatz Road off-site with 3-lanes at the intersection (one northbound receiving
13 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
lane, southbound left-turn lane, and a southbound shared through/right-turn lane) and a
dedicated westbound right-turn lane. The north leg of the intersection, if not fully aligned with
Glassford Avenue as part of this project in coordination with the property owner east of the site,
will result in Ersatz Road being offset by approximately 80 feet, as measured centerline to
centerline.
Staff has concerns about conflicting turn movements in this scenario due to inadequate offset
on a minor arterial road. ITD staff have noted that right-of-way acquisition is expected to be
completed by Summer 2023. The applicant should verify ITD's ability to dedicate additional
right-of-way at the intersection to accommodate improvements.

continuous center left-turn lane, and bike lanes.
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.
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 McMillan Road is designated in the MSM as a
Residential Arterial with 3-lanes and on-street bike lanes, a 46-foot street section within 78-feet
of right-of-way.
c. Applicant Proposal: The applicant is proposing to construct 5-foot wide detached concrete
sidewalk located 37-feet from the centerline of McMillan Road within a permanent right-of-way
easement, and an 8-foot wide planter strip and pavement widening to accommodate a
westbound right-turn lane to be installed at the Owyhee Storm Avenue and McMillan Road
intersection.
d. Staff Comments/Recommendations: The applicant's proposal to construct 5-foot wide
detached concrete sidewalk meets District policy and should be approved, as proposed.
The applicant's proposal to widen McMillan Road to accommodate the construction of a
westbound right-turn lane at Owyhee Storm Avenue is consistent with the findings and
15 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
recommendations of the traffic impact study and should be approved, as proposed. The
applicant should be required to coordinate the construction of the right-turn lane and any signal
modifications with Development Review staff; see Finding 2.
Consistent with ACHD's Frontage Improvements policy, the applicant will be required to widen
the McMillan Road pavement along the site frontage a minimum of 17-feet from centerline plus
a 3-foot wide gravel shoulder; east of where the turn lane will be constructed.
The applicant should be required to dedicate additional right-of-way to extend 2-feet behind the
back of sidewalk or provide a permanent right-of-way easement for all sidewalks located outside
of the dedicated right-of-way.
6. Owyhee Storm Avenue
a. Existing Conditions: There are no existing collector roadways within the site.
b. Policy:
Collector Street Policy: District policy 7206.2.1 states that the developer is responsible for
improving all collector frontages adjacent to the site or internal to the development as required
below, regardless of whether access is taken to all of the adjacent streets.
Master Street Map and Typologies Policy: District policy 7206.5 states that if the collector
street is designated with a typology on the Master Street Map, that typology shall be considered
for the required street improvements. If there is no typology listed in the Master Street Map,
then standard street sections shall serve as the default.
Street Section and Right-of-Way Policy: District policy 7206.5.2 states that the standard right-
of-way width for collector streets shall typically be 50 to 70-feet, depending on the location and
width of the sidewalk and the location and use of the roadway. The right-of-way width may be
reduced, with District approval, if the sidewalk is located within an easement; in which case the
District will require a minimum right-of-way width that extends 2-feet behind the back-of-curb on
each side.
The standard street section shall be 46-feet (back-of-curb to back-of-curb). This width typically
accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike
lanes.
Residential Collector Policy: District policy 7206.5.2 states that the standard street section
for a collector in a residential area shall be 36-feet (back-of-curb to back-of-curb). The District
will consider a 33-foot or 29-foot street section with written fire department approval and taking
into consideration the needs of the adjacent land use, the projected volumes, the need for
bicycle lanes, and on-street parking.
Off-Site Streets Policy: District Policy 7206.2.3 states that if the proposed development is not
served by a public street that is fully improved to urban standards (curb, gutter, sidewalk) or a
minimum 30-feet of pavement, then the developer shall provide 30-feet of pavement with 3-foot
wide gravel shoulders from the site to the public street specified by the District; OR the
developer shall provide 24-feet of pavement with 3-foot wide gravel shoulders and a minimum
6-foot wide detached asphalt/concrete pedestrian facility, from the site to a public street
specified by the District.
Alternatives to pavement widening including sidewalks and pathways or other proposals, may
be considered by the District. The extent of roadway improvements (improvement type and
length) will be determined by evaluating certain criteria. Criteria to establish improvement type
and length include but are limited to: traffic volumes (existing and projected); number of
pedestrians (existing and projected); location of pedestrian "attractors" and "generators" (i.e.
parks and schools); number of access points/streets serving the proposed development; usable

MER22-0065 / H-2023-0011
right-of-way; need for traffic calming; utilities and irrigation facilities. All utility relocation costs
associated with the off-site street widening shall be borne by the developer.
Sidewalk Policy: District policy 7206.5.6 requires a concrete sidewalk at least 5-feet wide to
be constructed on both sides of all collector 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.
New Collector ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master
Street Map (MSM) guide the right-of-way acquisition, collector street requirements, and specific
roadway features required through development. Owyhee Storm Avenue was identified on the
MSM with the street typology of Residential Collector. The new Owyhee Storm Avenue should
align with Owyhee Storm Avenue on the south side of McMillan Road and continue through the
property stubbing to the north. The Residential Collector typology as depicted in the Livable
Street Design Guide recommends a 2-lane roadway with bike lanes, a 36-foot street section
within 54-feet of right-of-way.
c. Applicant Proposal: Abutting the site, the applicant is proposing to construct Owyhee Storm
Avenue as a 46-foot street section, consisting of three travel lanes, bicycle lanes, curb, gutter,
8-foot wide planter strips, and 5-foot wide detached concrete sidewalk on the west side within
70-feet of right-of-way, with a 10-foot wide concrete sidewalk on the east side of within a
permanent right-of-way easement.
The applicant is proposing to construct a dedicated northbound right-turn lane at the driveway
proposed to be located 525-feet north of McMillan Road, consistent with the TIS
recommendations.
The applicant has proposed to construct the off-site portion of Owyhee Storm Avenue between
the site's south property line and McMillian Road with a 46-foot street section, consisting of:
three travel lanes, bicycle lanes, curb, gutter, 8-foot wide planter strips, and 5-foot wide
detached concrete sidewalk on the west side within 70-feet of right-of-way.
d. Staff Comments/Recommendations: The applicant's proposal to construct Owyhee Storm
Avenue as a 46-foot street section with 8-foot wide planter strips and 5-foot wide detached
concrete sidewalk on the west side and a 10-foot wide concrete sidewalk on the east side meets
District policy and is consistent with the TIS recommendations and should be approved, as
proposed. If street trees are desired, an 8-foot wide planter strip is required. For detached
sidewalk, the applicant may reduce the right-of-way to 2-feet behind the back of curb and
provide a right-of-way easement that extends from the right-of-way line to 2-feet behind the
back of curb.
The applicant's proposal to construct the dedicated northbound right-turn lane at the driveway
located 525-feet north of McMillan Road is consistent with the TIS recommendations and should
be approved, as proposed.
The applicant's proposal for construction of the off-site portion of Owyhee Storm Avenue
between the site's south property line and McMillian Road exceeds District off-site streets policy,
17 Cole Valley Christian Schools /

which requires at a minimum a 30-foot street section with 3-foot wide gravel shoulders OR a
24-foot wide street section, 3-foot wide gravel shoulders, and a 6-foot wide detached
asphalt/concrete pedestrian facility, from the site to a public street specified by the District. The
applicant's proposal to construct Owyhee Storm Avenue off-site with a 46-foot street section,
consisting of: three travel lanes, bicycle lanes, curb, gutter, 8-foot wide planter strips, and 5-foot
wide detached concrete sidewalk on the west side within 70-feet of right-of-way matches with
the improvements along the site frontage and should be approved, as proposed.
At a minimum, the off-site portion of Owyhee Storm Avenue should be constructed with a 30-
foot street section with 3-foot wide gravel shoulders OR a 24-foot wide street section, 3-foot
wide gravel shoulders, and a 6-foot wide detached asphalt/concrete pedestrian facility.
7. Ersatz Road
a. Existing Conditions: There are no existing collector roadways within the site.
b. Policy:
Collector Street Policy: District policy 7206.2.1 states that the developer is responsible for
improving all collector frontages adjacent to the site or internal to the development as required
below, regardless of whether access is taken to all of the adjacent streets.
Master Street Map and Typologies Policy: District policy 7206.5 states that if the collector

Street Section and Right-of-Way Policy: District policy 7206.5.2 states that the standard
right-of-way width for collector streets shall typically be 50 to 70-feet, depending on the location
and width of the sidewalk and the location and use of the roadway. The right-of-way width may
be reduced, with District approval, if the sidewalk is located within an easement; in which case
the District will require a minimum right-of-way width that extends 2-feet behind the back-of-
curb on each side.
The standard street section shall be 46-feet (back-of-curb to back-of-curb). This width typically
accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike
lanes.
Residential Collector Policy: District policy 7206.5.2 states that the standard street section
for a collector in a residential area shall be 36-feet (back-of-curb to back-of-curb). The District
will consider a 33-foot or 29-foot street section with written fire department approval and taking

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.
Half Street Policy: District Policy 7206.2.2 required improvements shall consist of pavement
widening to one-half the required width, including vertical curb, gutter, and concrete sidewalk
(minimum 7-foot attached for 5-foot detached), plus 12-feet of additional pavement widening
beyond the centerline established for the street to provide an adequate roadway surface, with
the pavement crowned at the ultimate centerline. A 3-foot wide gravel shoulder and a borrow
ditch sized to accommodate the roadway storm runoff shall be constructed on the unimproved
side.
c. Applicant Proposal: The applicant is proposing to construct Ersatz Road as a 46-foot street
section with three travel lanes, bicycle lanes on both sides, with vertical curb, gutter, 6-foot wide
planter strip, and 5-foot wide detached concrete sidewalk on the west side and 3-foot wide
gravel shoulder on the east side of the roadway within 70-feet of right-of-way abutting the site
and to align with Glassford Avenue.
d. Staff Comments/Recommendations: The applicant's proposal exceeds District policy for
requirements for constructing streets abutting a site and off-site streets, as well as sidewalk
width requirements. At a minimum, the applicant should be required to construct the collector
road abutting a site as '/2 of a 46-foot wide collector street section with vertical curb, gutter and
7-foot wide attached (or 5-foot wide detached) sidewalk on the improved side and 7-feet of
additional pavement widening (30-feet of pavement total) beyond the centerline for an adequate
travel way and 3-foot wide gravel shoulders and borrow ditch on the unimproved side; and
construct the off-site street with a minimum of 30-feet of pavement with 3-foot wide gravel
shoulders or 24-feet of pavement with 3-foot wide gravel shoulders and 6-foot wide pedestrian
facilities with the necessary lane configuration at the intersection with McMillan Road, as
discussed in Finding 2. The applicant should be required to dedicate right-of-way from 2-feet
behind the back of sidewalk to the site's west property line to accommodate the improvements.
Staff is also supportive of the applicant's proposal to fully construct Ersatz Road as a 46-foot
wide street section with a 5-foot wide detached sidewalk on the west side, as proposed. The
applicant may choose to fully improve Ersatz Road abutting the site and off-site or construct the
minimum improvements as discussed above. Ersatz Road should be constructed with vertical
curb and gutter where curb will be constructed.
If street trees are desired, an 8-foot wide planter strip is required. For detached sidewalk, the
applicant may reduce the right-of-way to 2-feet behind the back of curb and provide a right-of-
way easement that extends from the right-of-way line to 2-feet behind the back of curb.

MER22-0065 / H-2023-0011
8. Roadway Offsets
a. Existing Conditions: There are no existing roadways within the site. The nearest intersections
are Owyhee Storm Avenue south of McMillan Road, located 29-feet east of the site's west
property line; and Glassford Avenue south of McMillan Road, located 122-feet east of the site's
east property line.
b. Policy:
Local Street Intersection Spacing on Minor Arterials: District policy 7205.4.3 states that new
local streets should not typically intersect arterials. Local streets should typically intersect
collectors. If it is necessary, as determined by ACHD, for a local street to intersect an arterial,
the minimum allowable offset shall be 660-feet as measured from all other existing roadways
as identified in Table 1 a (7205.4.6).
Collector Offset Policy: District policy 7205.4.2 states that the optimum spacing for new
signalized collector roadways intersecting minor arterials is one half-mile.
c. Applicant's Proposal: The applicant is proposing to construct two collector roadways, Owyhee
Storm Avenue and Ersatz Road, north of McMillan Road to align with the existing Owyhee Storm
Avenue and Glassford Avenue to the south, respectively.
d. Staff Comments/Recommendations: The applicant's proposal to construct Owyhee Storm
Avenue and Ersatz Road align with the roadways to the south meets District policy and should
be approved, as proposed.
As discussed in Finding 4, this scenario is only feasible with ITD's acquisition of the right-of-
way to construct Ersatz Road to align Glassford Avenue. In the scenario where right-of-way is
not acquired by ITD in conjunction with the SH-16 extension, Ersatz Road's offset does not
District policy for collector roadway offsets or local street offset on a minor arterial roadway, and
would require the restriction of both Ersatz Road and Glassford Avenue intersections on
McMillan Road to right-in/right-out movements only.
9. Stub Streets
a. Existing Conditions: There are no existing roadways within the site.
b. Policy:
Stub Street Policy: District policy 7206.2.4.3 states that stub streets will be required to provide
circulation or to provide access to adjoining properties. Stub streets will conform with the
requirements described in Section 7206.2.4, except a temporary cul-de-sac will not be required
if the stub street has a length no greater than 150-feet. A sign shall be installed at the terminus
of the stub street stating that, "THIS IS A DESIGNATED COLLECTOR ROADWAY. THIS
STREET WILL BE EXTENDED AND WIDENDED IN THE FUTURE."
In addition, stub streets must meet the following conditions:
• A stub street shall be designed to slope towards the nearest street intersection within the
proposed development and drain surface water towards that intersection; unless an
alternative storm drain system is approved by the District.
• The District may require appropriate covenants guaranteeing that the stub street will remain
free of obstructions.
Temporary Dead End Streets Policy: 7206.2.4.4 requires that the design and construction
for cul-de-sac streets shall apply to temporary dead end streets. The temporary cul-de-sac
shall be paved and shall be the dimensional requirements of a standard cul-de-sac. The
developer shall grant a temporary turnaround easement to the District for those portions of the
cul-de-sac which extend beyond the dedicated street right-of-way. In the instance where a
20 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
temporary easement extends onto a buildable lot, the entire lot shall be encumbered by the
easement and identified on the plat as a non-buildable lot until the street is extended.
c. Applicant Proposal: The applicant is proposing to construct two collector roadways, Owyhee
Storm Avenue and Ersatz Road, to stub to the site's north property line located 2,023-feet north
of McMillan Road, measured property line to centerline.
d. Staff Comments/Recommendations: The applicant's proposal to stub two collector roadways
at the site's north meets District policy and should be approved, as proposed. The applicant
should be required to install signage at the terminus of both Owyhee Storm Avenue and Ersatz
Road stating that. "THIS IS A DESIGNATED COLLECTOR ROADWAY. THIS STREET WILL
BE EXTENDED AND WIDENDED IN THE FUTURE."
The applicant should be required to construct a temporary cul-de-sac turnaround at the terminus
of both roadways, as they extend more than 150-feet in length. The temporary cul-de-sac
turnaround should be paved and constructed meeting the dimensional standards of a standard
cul-de-sac.
10. Driveways
10.1 Owyhee Storm Avenue and Ersatz Road
a. Existing Conditions: There are no existing collector roadways within the site.
b. Policy:
Access 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.
District Policy 7206.1 states that the primary function of a collector is to intercept traffic from the
local street system and carry that traffic to the nearest arterial. A secondary function is to service
adjacent property. Access will be limited or controlled. Collectors may also be designated at
bicycle and bus routes.
Driveway Location Policy (Signalized Intersection): District policy 7206.4.3 requires
driveways located on collector roadways near a signalized intersection to be located outside
the area of influence; OR a minimum of 440-feet from the signalized intersection for a full-access
driveway and a minimum of 220-feet from the signalized intersection for a right-in/right-out only
driveway. Dimensions shall be measured from the centerline of the intersection to the centerline
of the driveway.
Driveway Location Policy (Stop Controlled Intersection): District policy 7206.4.4 requires
driveways located on collector roadways near a STOP controlled intersection to be located
outside of the area of influence; OR a minimum of 150-feet from the intersection, whichever is
greater. Dimensions shall be measured from the centerline of the intersection to the centerline
of the driveway.
Successive Driveways: District policy 7206.4.5 Table 1, requires driveways located on
collector roadways with a speed limit of 25 MPH and daily traffic volumes greater than 100 VTD
to align or offset a minimum of 245-feet from any existing or proposed driveway.
Driveway Width Policy: District policy 7206.4.6 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.
21 Cole Valley Christian Schools /
MER22-0065 / H-2023-0011
Driveway Paving Policy: Graveled driveways abutting public streets create maintenance
problems due to gravel being tracked onto the roadway. In accordance with District policy,
7206.4.6, 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 7206.4.6.
c. Applicant's Proposal: The applicant is proposing to construct two curb-return type driveways
on Ersatz Road, one 30-foot wide driveway located 530-feet north of McMillan Road and one
26-foot wide driveway located 1,743-feet north of McMillan Road, measured centerline to
centerline. The proposed 30-foot wide driveway located 530-feet north of McMillan Road is
proposed to construct a northbound right-turn lane to accommodate school pick-up/drop-off
traffic.
The applicant is proposing to construct two driveways on Owyhee Storm Avenue, one 36-foot
wide driveway located 525-feet north of McMillan Road and one 24-foot driveway located 1,208-
feet north of McMillan Road, measured centerline to centerline.
d. Staff Comments/Recommendations: The applicant's proposal to construct two curb-return
type driveways on Ersatz Road located 530-feet and 1,743-feet north of McMillan Road meets
District policy and should be approved, as proposed.
The applicant's proposal to construct two driveways on Owyhee Storm Avenue located 525-feet
and 1,208-feet north of McMillan Road meets District policy and should be approved, as
proposed. The applicant has indicated that ITD has been in discussion with the local
stakeholders in determination of field access approaches on Ersatz Road as part of the SH-16
Extension Phase 2 roadway improvements, which includes the roadway of and driveways to
Ersatz Road.
11. Bridge for West Tap Sublateral Canal Crossing
The District will require that the applicant submit the bridge plans for the crossing of the West Tap
Sublateral Canal (Ersatz Road) for review and approval prior to the pre-construction meeting and
final plat approval. Note: all plan submittals for bridges or pipe crossings of irrigation facilities should
be submitted to ACHD for review no later than December 15t"for construction in the following year
prior to irrigation season.
As discussed previously, ITD is in active works designing Ersatz Road and its connection to
McMillan Road as part of the SH-16 Phase 2 extension project and is working with the local
stakeholders for location, design, and construction of the roadway.
12. 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.
13. 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.

EXECUTIVE SUMMARY
Kittelson & Associates, Inc_ (Kittelson) has prepared a Transportation Impact Study (TIS) for the Cole
Valley Christian School Development. The proposed Cole Valley Christian School development is a
relocation and consolidation of two existing Cole Valley Christian School campuses — the existing
elementary school campus in Boise(in the SE corner of the Ustick Road/Maple Grove Road intersection)
and the existing high school!campus in Meridian(located near Main Street and Carlton Avenue),The new
consolidated Cole Malley Christian School campus wi II be located north of McMillan Road,east of Owyhee
Storm Avenue.The proposed site is currently vacant farmland and consists of is approximately 70 acres.
The development plan proposes to build a school campus to serve 1,825 students in preschool through
grade 12, including sports facilities and parking areas. The anticipated buildout and occupancy year for
the consolidated school campus is 2025,
The TIS resulted in the following findings and recommendations.
FINDINGS
Existing Conditions
+ All study intersections were found to operate acceptably during the existing weekday AM and
school PM peak hours,except for:
o Black Gat Road/US 20-26
■ This intersection operates exceeds ITD's desired LOS D threshold during the
school PM peak hour. Additionally, the northbound movement during the AM
peak and the westbound movement during the school PM peak hour exceed ITD
desired v/c threshold of 0.90,
■ It is noted that ACHD, not ITD, requested analysis of this intersection and the
intersection does meet ACHD signalized operating standards. The intersection
was recently re-built by ITD in 2021,
RTack Cat Road/McMillan Road
• This intersection operate at LOS F and has two overcapacity movements during
the AM peak hour and the westbound approach operated at LOS F during the
school PM peak hour,exceeding AC D operational standards_
■ The most recent ACHD Integrated Five Year Work plan identifies this intersection
as a future multi-lane roundabout. As a roundabout or an interim traffic signal,
the intersection will operate acceptably under existing conditions.
• All study roadway segments operate within the ACHD volume threshold under existing conditions
except for;
o McMillan Road(Black Cat Road to Ten Mile Road): During the school PM peak hour,this
segment of McMil Ian Road is expected to experience high westbound volumes. West of
San Vito Way,this segment is 2-lanes and east of San Vito way this segment is 3 lanes,

■ McMillan Road from Black Cat Road to San Vito Way is the segment that is a 2-
lane section and has a PM peak directional volume of 363, meeting ACHD
standard, while from San Vito Way to Ten Mile Road, where a peak direction
volume of 626 is experienced, is a 3-lane section. Conservatively, the overall
segment was compared to the 2-lane standard, but as noted,when considering
the sub-segment lane characteristics, each half of the segment meets the
ccrrespanding operating standard.
■ While the CIP identifies other adjacent segments of McMillan from Star Road to
Black Cat Road as future three-lane minor arterials, it is noted that the segment
from Black Cat Road to Ten Mile Road has not been identified.
Year 2025 Background Traffic Conditions
• Year 2025 background traffic analysis (without inclusion of site-generated traffic)found that all
study intersections are expected to operate acceptably during the weekday AM and school PM
peak hours under both the before and after SH-16 scenarios with the exceptions of:
o Black Cat Road/US 20-26
■ Similar to existing conditions, under both the before and after SH-16 scenarios,
this intersection operates at LOS E during the school PM peak hour, exceeding
ITD's desired threshold of LOS a but meeting ACHD LOS standard. Additionally,
under bath background scenarios, the westbound through-right, eastbound
through, and/or northbound through-right movements above ITD's desired v/c
ratio(v/c<0.90)during the AM and school PM peak hours but do operate under
capacity, meeting ACHD lane group standard except for the northbound thra ugh-
right lane group.
■ It is noted that ACHID, not ITD, requested analysis of this intersection and the
intersection does meet ACHD signalized operating standards. The intersection
was recently re-built by ITD in 2021.
o Black Cat Road/McMillan Road
■ This intersection and all movements operate at LOS f during the AM peak hour
and the westbound approach operated at LOS F during the school PM peak hour,
exceeding ACHD operational standards assuming no background improvements
The most recent ACHD Integrated Five Year WoA plan identifies this intersection
as a future multi-lane roundabout.
Mitigations analyses showed that signal warrants are met, and that the
intersection could meet ACHD standards as an interim traffic signal orthe
planned multilane roundabout.
• All study roadway segments operate within the ACHD volume threshold under year 2025
background traffic conditions for the before and after SH-16 scenarios,except for-
a McMillan Road (Black Cat Road to Ten Mile Road): As noted under existing conditions,
during the school PM peak hour,this segment of McMillan Road is expected to experience
high westbound volumes.

■ McMillan Road from Black Cat Road to San Vito Way is the segment that is a 2-
lane section and has a PM peak directional volume of 451, meeting ACHD
standard, while from San Vito Way to Ten Mile Road, where a peak direction
volume of 747 is experienced, is a 3-lane section, but exceeds the ACHD 3-lane
minor arterial volume standard.
■ If McMillan Road were reconstructed to provide median-control, with
channeliaed left-turn lanes,or widened to provide more than 1 travel lane in each
direction (exceeding the CIP identified 3-lane designation for McMillan Road),
ACHD roadway segment volumes threshold could be met.
■ While the CIP identifies other adjacent segments of McMillan from Star Road to
Black Cat Road as future three-lane minor arterials, it is noted that the segment
from Black Cat Road to Ten Mile Road has not been identified.
o Owyhee Storm Avenue(McMillan Road to Ustick Road): During the AM peak hour,the
southbound directional volume (451) exceeds ACHD collector 2-lane LO5 standard (425)
before and after SH-16. If Owyhee Storm Avenue were widened to a 3-lane collector,
providing a continuous left-turn lane,the increased ACHD LOS standard (530) could be
met.
Trip Generation
• Cole Valley Christian Schools is proposing to build a new preschool through grade 12 school
campus to serve approximately 1,825 students-
* The proposed school campus is estimated to generate a total of 4,132 daily net new trip ends,of
these 1,614 are estimated to occur in the weekday AM peak hour(916 inbound/698 outbound),
and 1,196 are estimated to occur in the weekday school PM peak hour (522 inbound / 574
outbound).
Year 2025 Total Traffic Conditions
• Year 2025 total traffic analysis found that all study intersections are expected to operate
acceptably during the weekday AM and school PM peak hours before and after SH-16 except for;
o Black Cat Road/US 20-26:
■ As under existing and background conditions, this intersection exceeds ITD
desired LOSS threshold in the school PM pear hour.Additionally, the eastbound,
westbound and northbound movements exceed ITD's desired We ratio for lane
groups (v/c<0,90) but are under capacity in the before SH -16 scenario_ In the
after-5H-15 scenario, the northbound movement is overcapacity
during the AM and school PM peak hours,exceeding ACHD lane group standard.

rXeco0ve Summary
■ If an additional 5 seconds were allocated to the northbound through-right
movernent.all movements could operate under capacity.With the 5H-16 project
rebuilding the US 20.26/SH-1f(McDermott Road}intersection,the coordination
and timing parameters of the adjacent arterial traffic signals (such as Black Cat
Road / US 20-26) should be revisited. It is recommended that with the
implementation of the SH-16 project,ACHD and ITD work together to operate in
a way to facilitate all movements operating within capacity.
c Star Road/McMillan Road:
* Under both the before and after SH-16 scenarios, the southbound left turn
movement is overcapacity, exceeding ACHD lane group standard holding the
existing signal timing parameters. In the after 5H-16 scenario, the overall
intersection v/c is 0.98 during the AM peak hour also exceeding ACHD standard.
• Signal timing mitigation adjustments re-allocating time to the future
higher volume southbound left-turn movement can allow for all lane
groups and the overall intersection to meet ACHD standards.
o Ersatz Place/Mcl'k+llillan Road;
• The southbound left movement at the Ersatz Place Road / McMillan Road
intersection operates at LO5 F and overcapacity during the AM and PM peak hours
of both the before and after 5H-16 scenarios as a stop-controlled movement_
• Per ACHD policy, signal warrants were evaluated which show the peak hour
warrant is met.
■ Installing a traffic signal mitigates the intersection to acceptable operations. The
Ersatz Place (Glassford Avenue)/ McMillan Road intersection would be located
approximately 1,3050 feet east of the Owyhee Storm Avenue/McMillan Road
which is closer than ACHD preferred half-mile signalized spacing on minor
arterials,Additional key considerations include;
• Without this access, the school access on Owyhee Storm Avenue will
experience significant queuing during peak times (see alternative access
scenario).
• A traffic signal would provide a signalize crossing of McMillan Road
connecting the Gander Creek residential development to Cale Malley
Christian School,facilitating a safer crossing cf potential students residing
near the school.
f Ersatz Place could serve as a key access to McMillan Road for other
properties located north of McMillan Road that may re-develop, as these
areas are identified by the City of Merdian for future low and medium
density residential uses_

■ With the planned extension of SH-16, ITD plans to relocate this intersection east
of its current location and change it's functionality—McDermott Road would no
longerconnectto US 20-26,rather itwould serve as a local access road only.Given
the planned relocation the intersection of McDermott Road/McMillan Road with
the SH-16 project, ACHD has requested that operations only be studied under
total traffic conditions ferthe before 5H-16 scenario.
■ In the before SH-16 scenario,the eastbound and westbound movements of this
intersection experience long delays resulting in LDS F, Both the eastbound and
westbound movements operate above capacity and therefore exceed ACHD
operating standards.
■ Per ACHD policy, signal warrants were evaluated which showed the peak hour,
four-hour, and eight-hour signal warrants are met,therefore a traffic signal was
evaluated.
5ignaIIzatIon of this intersection in a typical 3x3 intersection would mitigate is to
operate acceptably.However,beginning this summer ITD plans to begin construct
local access roads along McMillan Road (including McDermott Road) to provide
property access, in order to then construct the 5H-16 extension south of U5 20-
26, With the planned and funded SH-16 construction, McDermott Road will be
disconnected from US-20-26,which will reduce volumes on the north and south
approaches to the McDermott Road 1 McMillan Road intersection, As ITD has
funded plans to make fundamental changes to the McDermott Road/ McMillan
Road intersection with the funded 5H-16 project, signalixation is not
recommended.
o Black Cat Road/McMillan Road
■ As under existing and 2025 background traffic conditions,mitigation is needed at
the intersection of Black Cat Road / McMillan Road to operate within ACHD
standards.
■ Per ACHD policy, signal warrants were evaluated which showed the peak hour,
four hour and eight-hour volume-based MUTCD signal warrants are met under
total traffic 2025 volume conditions in both the before and after SH-16 scenarios.
■ An i nterim traffic signal or the planned multilane roundabout would meet ACHD
operating standards in the before SH-16 scenario_In the after SH-16 scenario,the
roundabout critical westbound approach is forecast to operate with a v/c of 0.91,
exceeding ACHD roundabout v/c standard of s 0_85, but meeting the lane group
standard of a traffic signal. It is anticipated that the ACHD roundabout design
team will further refine roundabout lane configuration needs considering the
design life future volumes of the intersection.

■ In both the before and after 5H-16 scenarios, the overall intersection operates
with an acceptable LO5 and with capacity but exceeds ACHD's V/c-0.90 standard
during the school PM peak hour. Under both scenarios, all lane groups operate
within capacity.
The current configuration of this intersection,which includes left and right turn
lanes on all approaches, reflects ACHD's planned ultimate configuration as
specified in the CIP for McMillan Road and Ten Mile Road, Therefore, since the
intersection operates at an acceptable LO5 and all lane groups all operate within
capacity, no further mitigation was explored.
o Star Road/McMillan Road
This intersection was recently signalized and meets ACHD operating standards
under total traffic conditions, however with the Cole Valley Christian School
campus in place,there is an increase in southbound left and westbound right AM
peak hour volumes that increases the length of the southbound left-turn queues
■ The current intersection configuration provides the minimum 100 feet of storage
for the southbound left-turn movement.If no other intersection widening occurs,
it is recommended that the southbound left-turn lane storage be extended to
provide 575 feet of storage, which may necessitate widening of Star Road.
Alternatively, if a westbound right-turn lane was added to the intersection to
provide at least 100 feet of storage, the southbound left-turn storage needs
would reduce to 300 feet. It is recommended that the development team and
ACHD further coordinate on the preferred configuration of the intersection.
o Owyhee Storm Avenue/McMillan Road
■ Though the recently signalized intersection can meet ACHD operating standards
under future conditions, assuming the planned extension of Owyhee Storm
Avenue north of McMillan Road, the addition of a fourth leg changes the
westbound left-turn storage needs of the intersection.
■ If the next phase of the Gander Creek development does not first widen McMillan
Road to three lanes from Ersatz Place (Glassford Avenue) to Owyhee Storm
Avenue, directly facilitating extension of the westbound left-turn lane striped
storage,the westbound left-turn lane should be extended to provide 275 feet of
storage,
• The Cole Valley Christian School development is not anticipated to add
any site trips to the westbound left-turn movement.
• Though four segments of McMillan Road and the iDwyhee Storm Avenue segment are forecast to
have peak hour, peak directional volumes exceeding ACHD segment standards, the applicable
school peakshoulder hour analyses showed Al study roadway segments operate within the ACHD

volume thresholds during the school shoulder hours.Therefore,in accordance with ACHD policy,
alternative mitigaticns were explored:
o Construction of continuous sidewalk or shared use path, widened shoulders and/or
bicycle lanes on Owyhee Storm Avenue from McMillan Road to the northern limit of
roadway construction
a Construction of Ersatz Place to Collector roadway standards, including continuous
sidewalk or shared use path from McMillan Road to the northern limit of the Cole Valley
Christian School Site
o Right-of-way permitting, construction of continuous sidewalk along the north side of
McMillan Road,from Owyhee Storm Avenue to Ersatz Place(GIassford Avenue)
o Right-of-way permitting,widening of MCMIIIian Road to provide safety shoulders
* Analyses of an interim, near-term access scenario which assumes that Ersatz Place cannot be
aligned with Glassford Avenue and,therefore,can only function as a right-in,right-out only stop-
controlled access to McMillan Road shows:
o Restriction of the left-out movement at Ersatz Place results in the Owyhee Storm
Avenue/McMillan Road intersection operating above the ACH D intersection v/c standard
during the AM peak hour under the before SFi 16 scenario,
a Under both the before and after SH-16 scenarios, Owyhee Storm Avenue southbound
left-turn queues at the Owyhee Storm Avenue/McMillan Road intersection would extend
several hundred feet north on Owyhee Storm Avenue,to even beyond the school access
driveway.If Owyhee Storm Avenue were extended to the north withfurther development
in the area, additional conflicting through volumes on Owyhee Storm Avenue would
significantly degrade the operations of the navy primary site driveway_
o The southbound Owyhee Storm Avenue AM and PM peak hour volumes would not meet
ACHD 3-lane collector segment volume standards.
o Though such a configuration could serve Cole Valley Christian School in the near-term,
the configuration would not ensure access longevity for the school, Particularly if other
properties redevelop and extend Owyhee Star Avenue to the north.
Site Access Evaluation
• Access spacing for site access paints were evaluated using ACHD"s access justification and spacing
requirements and found that all three proposed site access driveways meet ACHD policy spacing.
* The turn lane analysis using ACH❑ procedures shows turn lane warrants are met at these
locations;
o Site Access A/Owyhee Storm Avenue
Northbound Right-Turn Lane
o Site Access C/Ersatz Place
• Northbound Left-Turn Lane
o Ersatz Place Road/McMillan Road

+ Sight distance was not evaluated for the planned site access connections to the future roadway
extensions Since these have yet to be constructed.Sight distance was reviewed along McMillan
Road in the general vicinity of the planned extension of Owyhee Storm Avenue and near the
planned Ersatz Place connection. Looking east and west along McMillan Road, Sight distance
exceeds several hundred feet in both directions.
Special Considerations for Schools
* A school site check list for the development was completed consistent with Idaho Code of Idaho
Cade 67-6519 (3).The Cole Valley Christian School is unique in its operations as a private schflal
and one where the large majority(if not all)students are driven to and from school by personal
vehicle.
RECOMMENDATIONS
Based on the report's analyses and evaluation findings,the recommendations were developed:
* ACHD,ITD and area properties owners should work togetherto achieve alignment of Ersatz Place
with Glassford Avenue, rather than restrict Ersatz Place to right-in, right-out only. As a four-
approach intersection,the Ersatz Place/McMillan Road intersection should be signalized to serve
the Cale VaIIey Christian School development,
* Though ITD initial plans to construct Ersatz Place as a local access road, Ersatz Place Should be
built to collector roadway standards if it is to serve as a primary access route to Cale Valley
Christian School,and any other parcels that may re-develop north of McMillan Road.
* With the SH-16 project rebuilding the US 20-26/$H-16 {McDermott Road) intersection, the
coordination and timing parameters of the adjacent arterial traffic signals,such as Black Cat Road
/ US 20-26, should be revisited. It is recommended that with the implementation of the SH-16
project, ACHD and ITD work together to operate in a way to facilitate all movements operating
within capacity.
+ If the SH-16 project does not re-construction the McMillan Road/McDermott Road intersectian
prior to the opening cf Cole Valley Christian School campus, an interim traffic signal should be
provided.
+ If ACHD's planned construction of a multi-lane roundaboutatthe Black Cat Road/McMillan Road
intersection is not complete prior to the opening of Cole Valley Christian School campus, an
interim traffic signal should be considered.

Fxecuth a Summary
• ACHD and the deve I opment team should furt her coordinateto determine the preferred Star Road
/McMillan Road intersection widening/turn lane storage extension_
Given McMillan Road does not meet ACHD roadway segment LDS standards during the school
peak hours,but does during the shoulder hours,alterative mitigations for McMillian Road should
be implemented such as:
c Construction of continuous sidewalk or shared use path, widened shoulders and/or
bicycle lanes on Owyhee Storm Avenue from McMillan Road to the northern limit of
roadway construction
a Construction of Ersatz Place to Collector roadway standards, including continuous
sidewalk or shared use path from McMillan Road to the northern limit of the Cole Valley
Christian School site
a Right-of-way permitting, construction of continuous sidewalk along the north side of
McMillan Road,from Owyhee Storm Avenue to Ersatz Place�Glassford Avenue)
Right-af-way permitting,widening of McMillian Road to provide safety shoulders
• If the next phase of the Gander Creek development does riot first widen MCM11IIan Road to three
lanes from Ersatz Place (Glassford Avenue) to Owyhee Storm Avenue, directly facilitating
extension of the westbound left-turn lane striped storage,the westbound left-turn lane should
he extended to provide 275 feet of storage.
o The Cale Valley Christian School development is not anticipated to add any site trips to
the westbound left-turn movement.
• Construct all site accesses to the development with the following designations:
■ Pravide sidewalk connections from the public roadways at site driveways and connect
sidewalks onto the scheel site
■ Site driveways with access to public streets should provide sufficient stacking distance for
four vehicles(100feet)to ensure acceptable operation and accommodate larger vehicles,
including utility service and delivery vehicles_
■ Site accesses are assumed to match the existing grade of the connected roadway at the
intersection and back at least one car length.Significant changes to the approach grade could
impact the sight distances.
■ Shrubbery, weeds, and landscaping near the internal intersections and site access points
shouid be maintained to ensure adequate sight distance_

SPECIAL CONSIDERATIONS FOR SCHOOL DISTRICT FACILITIES
Idaho Cade 67-6519(3) requires specific elements to be studied for school facilities,same of which are
beyond ACHD TI5 requirements. The topics listed below are required to be addressed as part of the
transportation impact study for a new school.Topics that have been addressed in previous sections of
this report are identified but are not repeated in this section.Idaho Code requirements for school study
evaluation are:
1. Land use master plan
2. School bus plan
1 Access safety
4. Pedestrian plan
5. Crossing guard plan
6. Barriers between the highways and the school
7. Location of the school zone
8, Need for a flashing beacon
9. Need for traffic control
10. Anticipated future improvements
11. Speed on adjacent highways
12. Traffic volumes on adjacent highways
11 Effect upon a highway's level of service
24, Need for acceleration or deceleration lanes
15, Internal traffic circulation
16. Anticipated development on surrounding undeveloped parcels
17, Zoning in the vicinity
18. Access control on adjacent highways
19. Required striping and signing modifications
20. Funding for highway improvements to accornmodate the development
21. Proposed highway projects in the project vicinity
1. Land Use Master Plan
The proposed school property is currently in Ada County,located with the City of Meridian impact area.
The site is currently vacant former farmland and though the City of Meridian Zonings Map shows no
specific zoning,the proposed school property is shown as a future school location.
The City of Meridian Future tame Use Map identifies the areas immediately west, north and east of the
Cole Valley Christian School site are identified for low and medium density residential.South of McMillan
Road and west of the site, areas are identified for mixed use community surrounded by medium-high
density residential.

2.School bus plan
The existing Cole Valley Schools provide no student bussing,and only operates a limited shuttle between
the currently separate primary and elementary school campuses.As the proposed Cale Valley Christian
School would combine and replace the two existing campuses, no future shuttle service to another
location is anticipated.Additionally,at this time,no bussing of students tothe new campus is anticipated
consistent with existing operations, but may be further explored by school officials in the future.
3.Access Safety
The main site access points that will provide access to Cole Valley Christian school do not exist today.The
design and projected operations of the proposed access points was also reviewed against ACHO
standards to ensure they met all applicable requirements. Sight distance was not evaluated for the
planned connections to the future roadways since these have yet to be constructed. Intersection sight
distance was reviewed along McMillan Road in the general vicinity of the planned extension of Owyhee
Storm Avenue and near the planned Ersatz Place connection.Looking east and west along McMillan Road,
sight distance exceeds several hundred feet for both collector locations. Exhibit 1, previously discussed
in the Intersection Sight Distance section, provides the view to the east and west along McMillan Road
from the approximate location of the planned Ersatz Place roadway.

Exhiblt 1.Sight Distance at the Proposed McMillan Road/Ersatz Place Intersection
The fallowing recommendations have been identified to ensure adequate safety and operation at the
site access paints,internal intersections,and roadways:
• Remove miscellaneous vegetation and shrubbery,and potential obstructions along
McMillan Road as necessary to maintain adequate intersection sight distance.
Site accesses along McMillan Road should match the existing grade of McMillan
Road at the intersection.

• Shrubbery,weeds,and landscaping near the internal intersections and site access
paints should be maintained to ensure adequate sight distance_
■ If future widening occurs along McMillan Road,care should be taken to ensure
adequate intersection sight distance is maintained.
4. Pedestrian Plan
The pedestrian plan is comprised of the on-site pedestrian circulation and the off-site pedestrian
accessibility.
On-Site PedesViart Cr'rtufatfbn
Parent drop-off circulation is a challenge for all schools because of the high amount activity that occurs
in a short peak of 15 to 20 minutes.Given that this location will serve as an elementary, middle,and high
school the site is anticipating parent drop-off as well as some student drivers.
As shown in the following Internal Traffic Circularfon section,the two planned parent drop-off circulation
patterns have been designed so that students are dropped off curbside atthe building from the passenger
side of their vehicles and avoid the need for them to walk across the drop-off area_
As site plan design progresses, pedestrian walkway connections to the planned collector roadway
sidewalks should be provided on-site. Additionally, delineation of pedestrian walkways through the
various parking areas should be considered to facilitate safe travel of staff or older students that have
parked and need to access the school facility.
Off-Site Pedestrian Accessibility
Cole Valley Christian School students travel from all over the Treasure Valley to the school campuses and
no busing will be provided. Parental drop-off and pickup will be the primary mode of transportation for
students to and from the new campus location.A limited number of students may walk to the campus
from the new residential developments to the south. As other parcels in the area redevelop over time,
there may be addition local students walking to the campus. As the surrounding areas develops,ACHD
may further evaluate needs for school zones and pedestrian crossings in the area. There is recently
constructed sidewalk along the south side of McMillan Road along the frontage of the currently under
construction Gander Creek residential development,as well as the Oakes residential developments east
of McDermott Road_ In the future, new subdivisions will likely be required to provide sidewalk
connections to area roadways as the surrounding parcels redevelop.
The Owyhee Storm Avenue/McMillan Road traffic signal can facilitate signalized crossings of McMillan
Road.Assuming Ersatz Place is aligned with Glassford Avenue and signalized,this intersection would also
facilitate signalized crossings of McMillan Road, If the Ersatz Place/ McMillan Road intersection is not
signalized, some Gander Creek residents may have to walk as far as 2,000 feet west to Owyhee Storm
Avenuefora signalized crassingof McMiflan Road.Alternatively,should pedestrian demand fora crossing

of McMillan Road to reach the Cole Valley Christian School campus increase as the Gander Creek
development is occupied, pedestrian crossing treatments could be considered such as crossing signage
and flashing beacons in lieu of a traffic signal.
Directly west of the Gander Creek development, the areas south of McMillan Road are identified as
medium high density residential and mixed use community.Pedestrians travelingto orfrom these future
developmentareaswould likelytravel along McMillan Road,OrOwyhee 5tcrmAvenueto use the Owyhee
Storm Avenue/McMillan Road signalized intersection to reach the Cole Valley Christian School campus.
Sidewalks will be provided on the Owyhee Storm Avenue extension,as it will be built to ACH a collector
standards. It is also recommended that Ersatz Place be constructed to collector roadway standards and
provide sidewalk along the site frontage, as well as to the McMillan Road / Ersatz Place intersection.
Should the other areas north of McMillan Road along Owyhee Storm Avenue and Ersatz Place became
residential developments,these communities should be built with sidewalk connectivity to the collectors
and the need for additional pedestrian accommodations such as crosswalks,advance signing or beacons
could be revisited.
School Iorre
The location and design of school zones will be addressed duringthe design review process forthe school
based on direction of ACHD staff. Based on review of surrounding area, school zones are not typically
provided for high school facilities given the age of the students, though Cole Valley Christian School
campus will serve pre-IC through grade 12 students. The school fronts the extended Owyhee Storm
Collector and Ersatz Place, neither of which are arterial facilities and are anticipated to have posted
speeds ranging from 25-30 MPH, based on the existing segment of Owyhee Storm Avenue south of
McMillan Road which served Owyhee High School.The existing Cole Valley Christian School Elementary
campus does not have a designated school zone on Ustick Road or on Maple Grove Road, likely due to
the fact that the majority of students are driven to school and do no walk or bike to the campus.
5.Crossing Guard Plan
Off-site crossing guards will not be provided as the anticipated primary access mode will by passenger
vehicle.
A5 the Surrounding properties redevelopment,with more Students potentially walkingto school,officials
should regularly re-consider if crossing guards may become necessary.
6. Barriers between the Highway and the Schools
Based on the proposed site plan,there will be property in between the school property and McMillan
Road.The collector roadways that front the school are expected to be relatively law-volume roadways,
Should Owyhee Storm Avenue be extended to US 20-26 in the future, as is the long-term ACHD plan,
physical barriers and school zone designation may need to be revisited_

7-8. Location of the School Zone and Flashing Beacon
See the write-up under item#4 above.
9. Need for a Traffic,Control Signal
As identified in the previous sections of this report, all of the site access points to the new collector
facilities are forecast to operate acceptably as stop controlled driveways.The previous sections of this
report also identify the mitigation analysis for traffic signal or roundabout control at the study
intersections.
A traffic signal already exists at the Owyhee Storm Avenue/McMillan Road intersection.A traffic signal
should be provided at the Ersatz Place/McMillan Road intersection assuming it is aligned with 0assford
Avenue. In the interim,the Ersatz Place/McMillan Roan intersection could function as a right-in, right-
out only stop control intersection, but it is recommended that ACHD and ITD work to align Ersatz Place
with Classford Avenue in order to form a four-approach intersection.
10-14. Improvements, Speed,Traffic Volumes, Levels of Service,and Need for Acceleration
or Deceleration Lanes
See previous sections of this studythat document these steps.
15. Internal Traffic Circulation
Internal traffic circulation is anticipated to take place in the primary parking lots along the southern
frontage of the site,with two concurrent drop-off patterns fcr students to be drop-off at the main school
facility without needing to cross the parking areas. Exhibit 2 outlines the planned vehicular drop off
circulation patterns. Upon departure from the site, vehicles could continue east or west an McMillan
Road,or to the south on Owyhee Storm Avenue.

See previous sections of this study that document the proposed development.
17. Zoning in the Vicinity
The site and surrounding property is currently in unincorporated Ada County but within the City of
Meridian's area of impact. The site is currently vacant former farmland and though the City of Meridian
Zoning Map shows no specific zoning,the proposed school property is shown as a future school location.
18. Access Control on Adjacent Highways
Accesses for Cole Valley Christian School are all proposed as site driveways to the new roadways. As
outlined in the previous section of this report,the proposed Owyhee Storm Avenue mid-mile Collector is
identified on the ACHD Master Street Map, would be extended north of McMillan Road and all access
points meet ACHD access spacing standards for collector roadways.Though Ersatz Place may initially be
constructed by ITD to local road standards, alignment with Glassford Avenue, and development of the
Cole Valley Christian School would lead to Ersatz Place functioning as a collector roadway in the future.
Both proposed site access points to Ersatz Place meet ACHD access spacing standards for collector
roadways

19. Required Striping and Signing Modifications
Off-site intersection modifications are outlined in the previous section of this report. The following on-
site striping and signing modifications are recommended:
• Signing and striping of internal crosswalk locations.
• Delineation of pedestrian walkways through the parking lot.
• On-site signing and pavement markings for the parent drop-off/pick-up identifying
circulation direction, and curb loading area.
20. Funding of Highway Improvements to Accommodate Development
Funding for the improvements identified in the above sections of the report will be provided by the
development, or in coordination with other future developments in the area.
21. Proposed Highway Projects in the Vicinity
No near-term projects were identified in the immediate site vicinity. Based on a review of ACHD's Capital
Improvement Plan(CIP)and ITD's Idaho Transportation Improvement Program(TIP),planned projects on
