D. Traffic Impact Study- Summary and Findings
1. Traffic Impact Study
For developments located within the City of Meridian's Ten Mile Interchange Specific Area Plan
(TMISAP)ACHD defers the determination as to whether a proposed development is consistent with
the TMISAP to the City of Meridian. If a proposed development is consistent with the plan, then a
traffic impact study is generally not required. City of Meridian staff did not confirm that the proposed
development was consistent with the TMISP, nor did they make a formal request for a traffic impact
study.
In our review of the application materials provided by the applicant it appears that the land uses
proposed in the District at Ten Mile project are consistent with those identified in the TMISAP;
therefore, a traffic impact study was not required.
2. Analysis for Intersections
The applicant will be required to provide an intersection analysis for 3 intersections: the roundabout
proposed to be constructed on Grand Mogul/Villaggio Way located approximately 800-feet west of
Ten Mile; the Franklin Road/Umbria Hills intersection; and the Grand Mogul/Villaggio Way
intersection. This was discussed with the applicant during the pre-application phase of the project.
The analysis for these intersections will need to be completed and accepted prior to plan
approval for the first phase of this development and/or the issuance of an ACHD impact fee
assessment.
a) Roundabout
The preliminary plat shows the construction of a single lane roundabout at the Grand
Mogul/Villaggio Way/private road intersection located approximately 800-feet west of Ten
Mile Road. While staff is generally supportive of the use of roundabouts the applicant should
be required to submit a roundabout analysis to demonstrate that the proposed roundabout
will function adequately meeting ACHD's Level of Service standards and to ensure that the
appropriate lane configuration is constructed.
The roundabout analysis should be submitted prior to plan submittal for the first phase of
the development or the issuance of an ACHD impact assessment for a building permit if the
City of Meridian is going to allow the issuance of building permits ahead of the final plat.
Based on the analysis the roundabout design may need to be redesigned to accommodate
the anticipated traffic. ACHD will determine the ultimate configuration of the roundabout
based on the intersection analysis. The roundabout should be designed and constructed
consistent with section 5108 — Roundabout and 5188 — Roundabout Design Guide of
ACHD's policy manual.
b) Umbria Hills/Franklin Intersection
Umbria Hills, an existing collector roadway that stubs to the site's north property line, is
proposed to be extended into and through the site to intersect Grand Mogul/Villaggio Way.
This will provide access to Franklin Road. The existing portion of Umbria Hills was
constructed as a collector roadway as part of Baraya Subdivision and is anticipated to be
signalized at Franklin Road.
Because of this, the applicant should be required to submit a signal warrant analysis for the
Umbria Hills/Franklin Road intersection prior to plan submittal for the first phase of the
project or issuance of an ACHD impact fee for a building permit if the City of Meridian is
going to allow the issuance of building permits prior to final platting.
9 District at Ten Mile / MPP24-0006 / H-2023-0071
If the signal is warranted, then the applicant should be required to enter into a signal
agreement with ACHD to install a 2 X 3 X 5 signal at the Umbria Hills/Franklin Road
intersection. The applicant will be responsible for all costs associated with the installation
of the signal including design, construction, and hardware.
In order to ensure the intersection will be improved when warranted, the following items
must be in place prior to plan acceptance for the construction of Umbria Hills Way onto
Grand Mogul/Villaggio Way.
• Signal Agreement;
• Full design and approved plants for the intersection.
If the signal is not warranted with the first phase of the development,then the analysis should
include phasing with trip thresholds that identify when the signal would be warranted at the
intersection.
c) Grand Mogul/Villaggio Way/Black Cat Intersection
The applicant has indicated that they are coordinating with other area developers to
construct the extension of Grand Mogul/Villaggio Way from Ten Mile Road to Black Cat
Road. This would provide alternative access to the site via Black Cat Road which extends
over 1-84.
A traffic impact study prepared for Meridian Commerce Park (Black Cat Industrial), located
on the west side of Black Cat Road, indicated that the intersection of Grand Mogul/Villaggio
Way/Black Cat Road would warrant a signal in the future.
Because of this, the applicant should be required to submit a signal warrant analysis for the
Vanguard-Villaggio Way/Black Cat Road intersection prior to plan submittal for the phase of
the project or issuance of an ACHD impact fee for a building permit if the City of Meridian is
going to allow the issuance of building permits prior to final platting.
If the signal is warranted, then the applicant should be required to enter into a signal
agreement with ACHD to install a 5 X 5 signal at the Vanguard-Villago Way/Black Cat Road
intersection. The applicant will be responsible for all costs associated with the installation
of the signal including design, construction, and hardware.
In order to ensure the intersection will be improved when warranted, the following items
must be in place prior to plans acceptance for the construction of the Grand Mogul/Villaggio
Way connection to Black Cat Road.
• Signal Agreement;
• Full design and approved plans for the intersection.
If the signal is not warranted with the first phase of the development,then the analysis should
include phasing with trip thresholds that identify when the signal would be warranted at the
intersection.
10 District at Ten Mile / MPP24-0006 / H-2023-0071
E. Findings for Consideration
1. Ten Mile Interchange Specific Area Plan
The transportation element of the TMISAP is to guide transportation decisions in the Ten Mile
Interchange Area. It was developed concurrently with the Land Use and Design Elements and has
been designed to preserve the integrity of the arterial road system and the proposed Ten Mile
interchange; provide for the use of public transit; enhance pedestrian and bicycle mobility and
accessibility; and create transportation infrastructure and promote land use patterns that encourage
the sustainable use of resources and reduces demands on natural resources.
The TMISAP recommends the construction of 3 collector roads within the site, as shown below, as
well as the construction of Vanguard Way west of Ten Mile Road. The applicant has proposed to
construct the 3 collectors within the site and construct Vanguard Way from Ten Mile Road through
the site stubbing to the west. Although the alignment is configured differently than what is shown in
the TMISAP and MSM, the applicant's proposal meets the intent for connectivity to adjacent
properties consistent with the TMISAP and MSM.
2. Right-of-Way Vacation/Exchange
There is an existing portion of unopened unmaintained right-of-way that extends south from the
future Grand Mogul/Villaggio Way road. This right-of-way was acquired by ITD to provide local
access as part of ITD's Ten Mile Interchange project. The right-of-way has since been transferred
to ACHD. See the orange area below.

The applicant has proposed to incorporate this right-of-way into their site as parking lots and
buildings, necessitating the need to vacate the right-of-way. Prior to plan approval for the first phase
of the development or issuance of an impact fee assessment for a building permit the applicant
should be required to complete the vacation of the right-of-way or complete a vacation/exchange
of the right-of-way. The vacation or vacation/exchange is a separate process with its own
application, public hearing, and approval. A link to the vacation application can be found below.

https://www.achdidaho.org/home/showpublisheddocument/384/638499975082670000
3. Ten Mile Road/Grand Mogul/Villaggio Way Intersection
As part of ACHD's action on Vanguard Village/Meridian 118 subdivision located directly west of the
site that applicant was required to widen and modify the existing signalized intersection at Ten Mile
Road/Vanguard Way to accommodate the west leg of the intersection. The intersection
improvements include widening the west leg of the intersection with 2 receiving lanes, 2 eastbound
left-turn lanes, 1 eastbound through/right-turn lane and one dedicated eastbound right-turn lane.
This applicant is also required to adjust the striping on the east leg to reflect this configuration and
make any necessary modifications to the existing signal. ACHD is in the process of reviewing the
plans for this intersection.
If the applicant of Vanguard Village/Meridian 118 subdivision has not completed the plan approval
process or entered into a signal agreement to widen and modify the existing intersection prior to
plan approval for the first phase of the development and/or the issuance of an ACHD impact fee
assessment, then the applicant should be required to obtain plan approval and enter into a signal
agreement with ACHD for the intersection modifications.
The signal agreement should include requirements that the intersection is designed with 2 receiving
lanes, 2 eastbound left-turn lanes, 1 eastbound through/right-turn lane and one dedicated
eastbound right-turn lane on the east and west legs with the configuration or the north and south
legs remaining the same; that the applicant is responsible for all costs associated with the design,
and installation of the signal, hardware, and that improvements are not eligible for reimbursement
by ACHD.
In order to ensure the intersection will be improved when warranted, the following items must be in
place prior to plans acceptance for the construction of Grand Mogul/Villaggio Way onto Ten Mile
Road:
• Signal Agreement;
• Full design and approved plans for the intersection.
4. Ten Mile Road
a. Existing Conditions: Ten Mile Road is improved with 5-travel lanes, vertical curb, gutter, and
7-foot wide sidewalk abutting the site from Navigator Drive to Vanguard Way. Ten Mile Road is
improved with extruded curb, gutter, and a 7-foot wide asphalt pathway from Vanguard Way to
the site's north property line. There is 108-265 feet of right-of-way for Ten Mile Road (52-127
feet from centerline).
b. Applicant Proposal: The applicant is not proposing any improvements to Ten Mile Road
abutting the site.
c. Staff Comments/Recommendations: Consistent with ACHD's Pedestrian Facility policy, the
applicant should be required to construct a minimum of an 8-foot wide planter strip and a 10-
foot wide multi-use pathway on Ten Mile Road between Villaggio Way and Cobalt Drive abutting
the site tying into existing improvements on either side.
5. Grand Mogul/Villaggio Way
a. Existing Conditions: There is currently 45 to 115-feet of unopened right-of-way for Grand
Moguel/Villaggio Way at Ten Mile Road and extends to the site's west property line. Grand
Mogul /Villaggio Way (Vanguard Way) west of Ten Mile Road internal to the site has not yet
been constructed. A development agreement between ITD and ACHD was executed on June
6, 2012, with the dedication of the right-of-way west of Ten Mile Road for Grand Mogul/Villaggio
Way. ITD provided ACHD $458,500 to be used to reimburse the first developer for the future
12 District at Ten Mile / MPP24-0006 / H-2023-0071
improvements within the right-of-way to construct Grand Mogul /Villaggio Way with 30-feet of
pavement, curb, gutter and sidewalk on one side and gravel shoulder on the other side with
associated infrastructure as well as the construction of a 300 linear foot portion of a local road
intersecting Vanguard Way approximately 866-feet west Ten Mile Road.
b. Applicant Proposal:
The applicant is proposing to construct Villagio Way with three 11-foot wide travel lanes, vertical
curb, gutter, an 8-foot wide bioswale, and a 10-foot wide multi-use pathway as either a 37-foot
wide street section within 51-feet of right-of-way or a 54-foot wide street section with on-street
parking within 60-feet of right-of-way.
c. Staff Comments/Recommendations: The applicant's proposal meets District policy and
should be approved, as proposed. The use of a bioswale is an approved BMP and the
bioswales should be designed and constructed meeting the standards in section 8000 of
ACHD's policy manual.
The developer of the Vanguard Village/Meridian 118 development is working through the plan
approval process for Grand Mogul/Villaggio Way, and it is anticipated that these plans will be
approved soon. However, if the plans are not approved, then this applicant should be required
to construct Grand Mogul/Villaggio Way within the site, stubbing to the west as a 3-lane collector
roadway with vertical curb, gutter, 8-foot wide planter strip, and a 10-foot wide multi-use
pathway on both sides of the road.
Consistent with ACHD's prior action on this segment of roadway, the applicant should be
required to submit a right turn lane analysis for all driveways proposed onto Grand
Mogul/Villaggio Way. If the right turn lanes are warranted, then the dedicated right turn lanes
should be incorporated into the design of the roadway.
6. Cobalt Drive
a. Existing Conditions: Cobalt Drive is improved with 3-travel lanes, vertical curb, gutter, an 8-
foot wide planter strip, and 7-foot wide sidewalk abutting the site. There is 74-82 feet of right-
of-way for Cobalt Drive (37-47-feet from centerline). Cobalt Drive currently terminates in a cul-
de-sac turnaround located approximately 1,330-feet west of Ten Mile Road.
b. Applicant Proposal: The applicant is proposing to extend Cobalt Drive into the site to intersect
Umbria Hills Avenue as a 52-foot wide street section within 66-feet of right-of-way with three
11-foot wide travel lanes, on-street parking on both sides, vertical curb, gutter, an 8-foot wide
planter strip, and a 6-foot wide detached concrete sidewalk on either side.
c. Staff Comments/Recommendations: The applicant's proposal does not meet District policy,
as bike lanes are not proposed and are not consistent with the City of Meridian's TMISAP and
should not be approved, as proposed.
The applicant should be required to extend Cobalt Drive into the site and construct the roadway
with 3-travel lanes, 5-foot wide on-street bike lanes, vertical curb, gutter (47-foot wide street
section), an 8-foot wide planter strip, and a minimum 5-foot wide detached concrete sidewalk
abutting the site. This would match the existing improvements on Cobalt Drive located directly
east of the site. No parking would be allowed on this street section. The applicant would be
required to coordinate a signage program for the "NO PARKING" signs with District
Development Review staff.
As an alternative to the on-street bike lanes and if required, by the City of Meridian then in lieu
of constructing on-street bike lanes, 10-foot wide multi-use pathways on both sides of the
roadway may be constructed. Under this scenario, on-street parking can be accommodated.

a. Staff comments/Recommendations: Given the mix of uses (residential, office, commercial,
entertainment, industrial) proposed on the north and south sides of Grand Mogul/Villaggio Way
and on Umbria Hills and because this is a collector street to collector street intersection, staff
recommends that the applicant install a Pedestrian Hybrid Beacon (PHB) on Grand
Mogul/Villaggio Way at Umbria Hills. This will provide a protected pedestrian crossing allowing
better pedestrian connectivity between the north and south portions of the site.
The applicant should be required to design and install the PHB when Umbria Hills is extended
to intersect Grand Mogul/Villaggio Way. The applicant will be required to enter into a signal
agreement for the PHB and will be responsible for all costs associated with the installation of
the PHB including design, construction, and hardware.
In order to ensure the PHB is installed when Umbria Hills is constructed to intersection Grand

section of Grand Mogul/Villaggio Way. If these plans are approved and construction starts then
15 District at Ten Mile / MPP24-0006 / H-2023-0071
a stub street to the west is not required; however, if this project moves forward before Vanguard
Village/Meridian 118 then a stub street to the west should be constructed. The applicant should
be required to install a sign at the terminus of the stub street which states that "THIS IS A
DESIGNATED COLLECTOR ROADWAY. THIS STREET WILL BE EXTENDED AND
WIDENDED IN THE FUTURE."
Provide a temporary turnaround at the terminus of Grand Mogul/Villaggio Way since the stub
street is longer than 150-feet. The temporary cul-de-sac shall be paved and shall be the
dimensional requirements of a standard cul-de-sac. The developer should 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 temporary easement extends onto a
buildable lot, the entire lot should be encumbered by the easement and identified on the plat as
a non-buildable lot until the street is extended.
13. Driveways
13.1 Ten Mile Road
a. Existing Conditions: There is a 15-foot wide unimproved driveway located 450-feet south of
Vanguard Way (measured centerline-to-centerline).
b. Applicant's Proposal: The applicant is proposing to close this driveway.

north side of Grand Mogul/Villaggio Way located 630-feet west of Ten Mile Road.
• Two 32-foot wide driveways on the north and south sides of Grand Mogul/Villaggio Way
located 1,440-feet east of the west property line. These driveways are proposed to align
centerline to centerline.
• Two 40-foot wide driveways on the north and south sides of Grand Mogul/Villaggio Way
located at the west property line. These driveways are proposed to align centerline to
centerline.
c. Staff Comments/Recommendations: The applicant's proposal meets District policy with the
exception of the 2 right-in/right-out only driveways proposed on the north and south sides of
Grand Mogul/Villaggio Way.
The right-in/right-out driveway on the south side of Grand Mogul/Villaggio Way located 424-feet
west of Ten Mile is located within the influence area of the Grand Mogul/Villaggio Way
intersection. The right-in/right-out driveway proposed on the north side of Grand Mogul/Villaggio
Way is proposed to be located within the influence area of the proposed roundabout. ACHD
policy states that "access is typically prohibited within the influence area of the intersection".
This applies to both roundabouts and signalized intersections. Additionally, the driveways do
not meet the required offset of 260-feet.
16 District at Ten Mile / MPP24-0006 / H-2023-0071
Staff recognizes there is a desire to provide access to this part of the development and
recommends that these 2 driveways be relocated outside the influence areas of both the
signalized intersection and roundabout and be designed to align centerline to centerline. A
revised site plan should be submitted to ACHD for review and approval of the driveway locations
prior to plan submittal.
The driveways should be constructed as paved curb return type driveways.

d. Staff Comments/Recommendations: The applicant's proposal meets District policy and
should be approved as proposed with the exception of two driveways proposed to offset by only
50-feet; a driveway proposed on the south side of Navigator Drive located 618-feet west of the
east property line and a driveway on the north side of Navigator Drive located 668-feet west of
the east property line. These driveways should be redesigned to align centerline to centerline
and offset a minimum of 260-feet from any other driveways.
The driveways should be constructed as paved curb return type driveways.
14. Bridge for Purdham Gulch Drain Crossing
The District will require that the applicant have ACHD approved plans for the crossing of the Purdam
Gulch Drain prior to the pre-construction meeting and final plat approval. Note: Timing of project
plan submittals should take into account review times, lead time for precast members and potential
roadway closures. To ensure construction prior to irrigation season, approval of the project plans
must be attained by January 15t". The District retains the right to modify road closure approvals on
any project based on the needs of the District. Construction of projects approved after January 15t"
may be postponed until after irrigation season is over in October. It is recommended that bridge
submittals be submitted before the end of the current irrigation season to ensure the best time frame
for construction is attained. Submittals will need to include the street section extending over the
bridge to ensure the requirements of the roadway are met.
15. Other Access
Ten Mile Road is classified as a principal arterial roadway; Villagio Way, Cobalt Drive, Umbria Hills
Avenue, and Navigator Drive are classified as collector roadways. Other than the access
specifically approved with this application, direct lot access is prohibited to these roadways and
should be noted on the final plat.
18 District at Ten Mile / MPP24-0006 / H-2023-0071
F. Policy
1. Federal Accessibility Design Guidelines and Standards

Board's Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way(PROWAG), 36
CFR Part 1190, September 7, 2023; (Also see, https//www.access-board.gov/prowag and
httpsHwww.access-board.gov/files/prowag/planning-and-design-for-alternatives.pdf for additional
information).
2. Minor Improvements
Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing
Highways adjacent to a proposed development may be required. These needed transportation
facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or
bike lane construction or replacement (with physical buffers if missing and needed); construction of
transitional sidewalk segments; crosswalk construction or replacement; curb and gutter
construction or replacement; repair, replacement or expansion of curb extensions; replacement of
unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation
features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle,
pedestrian and bicycle traffic control devices; and other similar items. The current version of
PROWAG will determine the applicable accessibility requirements for alterations and elements
added to existing streets. ACHD staff is responsible for identifying the minor improvements that
would be proportionate to the size and complexity of the development.
3. Livable Street Performance Measures
District policy 7203.8 states that ACHD has adopted performance measures (level of stress) for
evaluating the experience of bicyclists and pedestrians. ACHD seeks to create a transportation
network that serves all ages and abilities. Bike and pedestrian facilities built through development
should achieve a bike and pedestrian level of traffic stress 1 or 2, with no new bike lane below a
minimum of 5-feet.
4. Ten Mile Road
Arterial Roadway Policy: District Policy 7205.2.1 states that the developer is responsible for
improving all street frontages adjacent to the site regardless of whether or not access is taken to all
of the adjacent streets. Improvements shall include transitional segments in accordance with the
current version of PROWAG.
Master Street Map and Typology Policy: District Policy 7205.5 states that the design of
improvements for arterials shall be in accordance with District standards, including the Master
Street Map, Livable Streets Design Guide, and the most current ACHD Livable Streets Performance
Measures Plan as adopted by the ACHD Commission. The developer or engineer should contact
the District before starting any design.
Street Section and Right-of-Way Width Policy: District Policies 7205.2.1 & 7205.5.2 state The
standard 5-lane street section shall be 59-feet (back-of-curb to back-of-curb). This width typically
accommodates two travel lanes in each direction, a continuous center left-turn lane or landscaped
median with intermittent turn lanes, and curbs and gutters. A 5-lane road shall also include a
minimum 10-foot wide multi-use path on both sides with an 8-foot wide buffer from back-of-curb.
Other bike facility treatments as defined in the ACHD Bike Master Plan may be approved at the
discretion of the ACHD Development Review Supervisor. If an interim on-street bike lane is required
in order to connect to existing facilities, the street section shall be 75-feet to allow for a 5-foot wide
bike lane and 3-foot wide painted buffer. The standard right-of-way width for a 5-lane arterial is 100-
feet.
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
19 District at Ten Mile / MPP24-0006 / H-2023-0071
fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the
Impact Fee Service Area.
No compensation will be provided for right-of-way on an arterial that is not listed as impact fee
eligible in the Capital Improvements Plan.
The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor
for future capacity improvements, as provided in Section 7300.
Pedestrian Facilities: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide are
required on both sides of all arterial streets. A parkway strip at least 8-feet wide between the back-
of-curb and street edge of the sidewalk is required to provide increased safety and protection of
pedestrians. Alternatively, on roadways identified for improvement in the Capital Improvement Plan,
a minimum 10-foot wide multi-use path may be required. The path shall be placed in accordance
with planned buildout in the Master Street Map with a minimum 8-foot wide planter strip as
measured to the closest edge of the path. Street trees are encouraged between the pedestrian
facility and the roadway when irrigation and maintenance will occur by the adjacent property owner
or HOA through an approved license agreement. Consult the District's planter width policy if trees
are to be placed within the parkway strip. In some instances, to match existing conditions, a
minimum 7-foot wide sidewalk may be constructed next to the back-of-curb. ACHD Development
Review staff will be responsible for determining the required facility. Vertical hardscape alternatives
to street trees may be considered in the buffer space when street trees are not practicable.
Detached sidewalks and multi-use paths are encouraged and should be parallel to the adjacent
roadway. Pedestrian facilities will only be allowed to deviate from a straight line parallel to the
roadway when authorized by Development Review staff to accommodate site specific conditions
(i.e., street trees, utilities, etc.).
Appropriate easements shall be provided if public pedestrian facilities are placed out of the right-of-
way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind
the back edge of the pedestrian facility. Pedestrian facilities shall either be located wholly within the
public right-of-way or wholly within an easement.
Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each
pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable
warning surface in accordance with the current version of PROWAG.
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 Ten Mile Road is designated in the MSM as a
Residential Mobility Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within
100-feet of right-of-way.
5. Villagio Way
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. Improvements shall
include transitional segments in accordance with ADA and the current version of PROWAG.
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. ACHD reserves the right to require bicycle and pedestrian
facilities above those identified in the Livable Streets Design Guide and Master Street Map to
ensure the safest facility possible based on current best practice.
20 District at Ten Mile / MPP24-0006 / H-2023-0071
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 or multi-use path and the location and use of the roadway. The right-of-way
width may be reduced, with District approval, if the sidewalk or multi-use path 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 47-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. If a multi-use path is determined to be the required treatment, the street section shall be
reduced to 37-feet. If it is determined a continuous center left-turn lane is not appropriate and a
path is installed, the street section may be reduced to 26-feet.
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.
At the discretion of Traffic Engineering staff, adjustments may be made to the street section,
including removal of the continuous center turn lanes or modification to lane widths, where no
driveways or intersections are present or to ensure adequate space for pathways and buffers.
Pedestrian Facilities: 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 8-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. Sidewalk constructed next to the back-of-curb shall be a minimum of 7-feet wide.
Alternatively, on roadways identified as low-stress bikeways in ACHD's Bike Master Plan, a
minimum 10-foot wide multi-use path may be required in lieu of sidewalks. ACHD Development
Review staff will be responsible for determining the required facility. The path shall be built 8-feet
behind the back-of-curb as measured to the closest edge of the path. Street trees are encouraged
between the pedestrian facility and the roadway when irrigation and maintenance will occur by the
adjacent property owner or HOA through an approved license agreement. Vertical hardscape
alternatives to street trees may be considered in the buffer space when street trees are not
practicable.
Pedestrian facilities should be parallel to the adjacent roadway. Pedestrian facilities will only be
allowed to deviate from a straight line when authorized by Development Review staff to meet site
specific conditions (i.e., street trees, utilities, etc.).
Appropriate easements shall be provided if public sidewalks or multi-use paths are placed out of
the right-of-way. The easement shall encompass the entire area between the right-of-way line and
2-feet behind the back edge of the sidewalk or multi-use path. Sidewalks shall either be located
wholly within the public right-of-way or wholly within an easement.
Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each
pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable
warning surface in accordance with the current version of PROWAG.
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. A new collector roadway was identified on the MSM with the street
typology of Towncenter Collector. The new collector roadway should align with Vanguard Way on
the east side of Ten Mile Road and continue through the property stubbing to the west. The
Towncenter Collector typology as depicted in the Livable Street Design Guide recommends a 2-3
21 District at Ten Mile / MPP24-0006 / H-2023-0071
lane roadway with bike lanes, and on street parking, a 36-46 foot street section within 50-70 feet of
right-of-way.

Appropriate easements shall be provided if public sidewalks or multi-use paths are placed out of
the right-of-way. The easement shall encompass the entire area between the right-of-way line and
2-feet behind the back edge of the sidewalk or multi-use path. Sidewalks shall either be located
wholly within the public right-of-way or wholly within an easement.
Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each
pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable
warning surface in accordance with the current version of PROWAG.
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. This segment of Cobalt Way is designated in the MSM as a
Towncenter Collector with 3-lanes and on-street bike lanes, a 47-foot street section within 74-feet
of right-of-way.
7. Umbria Hills Avenue
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. Improvements shall
include transitional segments in accordance with ADA and the current version of PROWAG.
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. ACHD reserves the right to require bicycle and pedestrian
facilities above those identified in the Livable Streets Design Guide and Master Street Map to
ensure the safest facility possible based on current best practice.
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 or multi-use path and the location and use of the roadway. The right-of-way
width may be reduced, with District approval, if the sidewalk or multi-use path 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 47-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. If a multi-use path is determined to be the required treatment, the street section shall be
reduced to 37-feet. If it is determined a continuous center left-turn lane is not appropriate and a
path is installed, the street section may be reduced to 26-feet.
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.
At the discretion of Traffic Engineering staff, adjustments may be made to the street section,
including removal of the continuous center turn lanes or modification to lane widths, where no
driveways or intersections are present or to ensure adequate space for pathways and buffers.
Pedestrian Facilities: 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 8-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. Sidewalk constructed next to the back-of-curb shall be a minimum of 7-feet wide.
Alternatively, on roadways identified as low-stress bikeways in ACHD's Bike Master Plan, a
23 District at Ten Mile / MPP24-0006 / H-2023-0071
minimum 10-foot wide multi-use path may be required in lieu of sidewalks. ACHD Development
Review staff will be responsible for determining the required facility. The path shall be built 8-feet
behind the back-of-curb as measured to the closest edge of the path. Street trees are encouraged
between the pedestrian facility and the roadway when irrigation and maintenance will occur by the
adjacent property owner or HOA through an approved license agreement. Vertical hardscape
alternatives to street trees may be considered in the buffer space when street trees are not
practicable.
Pedestrian facilities should be parallel to the adjacent roadway. Pedestrian facilities will only be
allowed to deviate from a straight line when authorized by Development Review staff to meet site
specific conditions (i.e., street trees, utilities, etc.).
Appropriate easements shall be provided if public sidewalks or multi-use paths are placed out of
the right-of-way. The easement shall encompass the entire area between the right-of-way line and

9. Echo Canyon Avenue
Local Roadway Policy: District Policy 7207.2.1 states that the developer is responsible for
improving all local street frontages adjacent to the site regardless of whether or not access is taken
to all of the adjacent streets.
Street Section and Right-of-Way Policy: District Policy 7207.5 states that right-of-way widths for
all local streets shall generally not be less than 47-feet wide and that the standard street section
shall be 33-feet (back-of-curb to back-of-curb).
Standard Urban Local Street-33-foot Street Section and Right-of-way Policy: District Policy
7207.5.2 states that the standard street section shall be 33-feet (back-of-curb to back-of-curb) for
developments with any buildable lot that is less than 1 acre in size. This street section shall include
curb, gutter, and minimum 5-foot wide concrete sidewalks on both sides and shall typically be
constructed within 47-feet of right-of-way.
For the City of Kuna and City of Star: Unless otherwise approved by Kuna or Star, the standard
25 District at Ten Mile / MPP24-0006 / H-2023-0071
street section shall be 36-feet (back-of-curb to back-of-curb) for developments with any buildable
lot that is less than 1 acre in size. This street section shall include curb, gutter, and minimum 5-foot
wide concrete sidewalks on both sides and shall typically be constructed within 50-feet of right-of-
way.
Continuation of Streets Policy: District Policy 7207.2.4 states that an existing street, or a street
in an approved preliminary plat, which ends at a boundary of a proposed development shall be
extended in that development. The extension shall include provisions for continuation of storm
drainage facilities. Benefits of connectivity include but are not limited to the following:
• Reduces vehicle miles traveled.
• Increases pedestrian and bicycle connectivity.
• Increases access for emergency services.
• Reduces need for additional access points to the arterial street system.
• Promotes the efficient delivery of services including trash, mail and deliveries.
• Promotes appropriate intra-neighborhood traffic circulation to schools, parks, neighborhood
commercial centers, transit stops, etc.
• Promotes orderly development.
Sidewalk Policy: District Policy 7207.5.7 states that five-foot wide concrete sidewalk is required
on both sides of all local street, except those in rural developments with net densities of one dwelling
unit per 1.0 acre or less, or in hillside conditions where there is no direct lot frontage, in which case
a sidewalk shall be constructed along one side of the street. Some local jurisdictions may require
wider sidewalks.
The sidewalk may be placed next to the back-of-curb. Where feasible, a parkway strip at least 8-
feet wide between the back-of-curb and the street edge of the sidewalk is recommended to provide
increased safety and protection of pedestrians and to allow for the planting of trees in accordance
with the District's Tree Planting Policy. If no trees are to be planted in the parkway strip, the
applicant may submit a request to the District, with justification, to reduce the width of the parkway
strip.
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.
Cul-de-sac Streets Policy: District policy 7207.5.8 requires cul-de-sacs to be constructed to
provide a minimum turning radius of 50-feet; in rural areas or for temporary cul-de-sacs the
emergency service providers may require a greater radius. Landscape and parking islands may be
constructed in turnarounds if a minimum 29-foot street section is constructed around the island.
The pavement width shall be sufficient to allow the turning around of a standard AASHTO SU design
vehicle without backing. The developer shall provide written approval from the appropriate fire
department for this design element.
The District will consider alternatives to the standard cul-de-sac turnaround on a case-by-case
basis. This will be based on turning area, drainage, maintenance considerations and the written
approval of the agency providing emergency fire service for the area where the development is
located.
26 District at Ten Mile / MPP24-0006 / H-2023-0071
10. Roadway Offsets
Local Street Intersection Spacing on Principal 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 1,320-feet as measured from all other existing roadways as
identified in Table 1 b (7205.4.7).
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.
District policy 7205.4.2 states that the optimum spacing for new signalized collector roadways
intersecting principal arterials is one half-mile.
District policy 7206.4.2 states that the preferred spacing for new collectors intersecting existing
collectors is '/4 mile to allow for adequate signal spacing and alignment.
District policy 7206.4.3 states that access is typically prohibited within the influence area of an
existing or future roundabout intersection, which is generally considered the area from the
intersection to the far end of the splitter islands.
District policy 7206.4.5, states that the preferred spacing for a new local street intersecting a
collector roadway to align or offset a minimum of 330-feet from any other street (measured
centerline to centerline).

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 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.
12. Driveways
12.1 Ten Mile Road
27 District at Ten Mile / MPP24-0006 / H-2023-0071
Access Points Policy: District Policy 7205.4.1 states that all access points associated with
development applications shall be determined in accordance with the policies in this section and
Section 7202. Access points shall be reviewed only for a development application that is being
considered by the lead land use agency. Approved access points may be relocated and/or
restricted in the future if the land use intensifies, changes, or the property redevelops.
Access Policy: District policy 7205.4.7 states that direct access to principal arterials is typically
prohibited. If a property has frontage on more than one street, access shall be taken from the street
having the lesser functional classification. If it is necessary to take access to the higher classified
street due to a lack of frontage, the minimum allowable spacing shall be based on Table 1 b under
District policy 7205.4.7, unless a waiver for the access point has been approved by the District
Commission. Driveways, when approved on a principal arterial shall operate as a right-in/right-out
only, and the District will require the construction of a raised median to restrict the left turning
movements.
Driveway Location Policy: District policy 7205.4.7 requires driveways located on principal arterial
roadways to be located a minimum of 355-feet from the nearest intersection for a right-in/right-out
only driveway. Full-access driveways are not allowed on principal arterial roadways.
Successive Driveways: District policy 7205.4.7 Table 1 b, requires driveways located on principal
arterial roadways with a speed limit of 40 MPH to align or offset a minimum of 400-feet from any
existing or proposed driveway.
Driveway Width Policy: District policy 7205.4.8 restricts high-volume driveways (100 VTD or
more)to a maximum width of 36-feet and low-volume driveways (less than 100 VTD)to a maximum
width of 30-feet. Curb return type driveways with 30-foot radii will be required for high-volume
driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for
low-volume driveways with less than 100 VTD.
Driveway Paving Policy: Graveled driveways abutting public streets create maintenance
problems due to gravel being tracked onto the roadway. In accordance with District policy,
7205.4.8, the applicant should be required to pave the driveway its full width and at least 30-feet
into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance
with Table 2 under District Policy 7205.4.8.
Temporary Access Policy: District Policy 7202.4.2 identifies a temporary access as that which
"is permitted for use until appropriate alternative access becomes available". Temporary access
may be granted through a development agreement or similar method, and the developer shall be
responsible for providing a financial guarantee for the future closure of the driveway.
Cross Access Easements/Shared Access Policy: District Policy 7202.4.1 states that cross
access utilizes a single vehicular connection that serves two or more adjoining lots or parcels so
that the driver does not need to re-enter the public street system.
12.2 Villaggio Way, Cobalt Drive, Umbria Hills Avenue, & Navigator Drive
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.
28 District at Ten Mile / MPP24-0006 / H-2023-0071
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.
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.
Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing
Highways adjacent to a proposed development may be required. These needed transportation
facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or
bike lane construction or replacement (with physical buffers if missing and needed); construction of
transitional sidewalk segments; crosswalk construction or replacement; curb and gutter
construction or replacement; repair, replacement or expansion of curb extensions; replacement of
unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation
features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle,
pedestrian and bicycle traffic control devices; and other similar items. The current version of
PROWAG will determine the applicable accessibility requirements for alterations and elements
added to existing streets. ACHD staff is responsible for identifying the minor improvements that
would be proportionate to the size and complexity of the development.
13. 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.
14. 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.
29 District at Ten Mile / MPP24-0006 / H-2023-0071
15. Gas Pipeline: The Williams Pipeline falls within the proposed development. Coordination with the
owner of the pipeline prior to final design is recommended to ensure that their requirements are
met. ACHD requires written approval from the owner of the pipeline prior to plan acceptance if
public street improvements are proposed or required within the pipeline easement.
16. Pathway Crossings: United States Access Board R304.5.1.2 Shared Use Paths. In shared use
paths, the width of curb ramps runs and blended transitions shall be equal to the width of the shared
use path.
AASHTO's Guidelines for the Development of Bicycle Facilities 5.3.5 Other Intersection
Treatments: The opening of a shared use path at the roadway should be at least the same width
as the shared use path itself. If a curb ramp is provided, the ramp should be the full width of the
path, not including any flared sides if utilized. . . . Detectable warnings should be placed across the
full width of the ramp.
FHWA's "Designing Sidewalks and Trails for Access" (1999) reflected common ADA-related
concepts: Chapter 6, Page 16-6: The width of the ramp should be at least as wide as the average
width of the trail to improve safety for users who will be traveling at various speeds. In addition, the
overall width of the trail should be increased, so the curb ramp can be slightly offset to the side.
The increased width reduces conflict at the intersection by providing more space for users at the
bottom of the ramp.
