A. Site Specific Conditions of Approval
1. Construct one access point to this site. Prior to ACHD's signature on the final plat that contains the
10011 single family building lot, provide secondary access to the site. Or, as an alternative, stop final
platting until the secondary public street access is available.
2. If Skyranch moves forward prior to the construction of Sublimity Avenue, stub Street A to the
adjacent parcel to the east until Sublimity is constructed by Brighton Development.
OR construct Sublimity Avenue as '/2 of a 36-foot wide collector street section with vertical curb,
gutter and 5-foot wide detached or 7-foot wide attached concrete sidewalk on the west side of the
roadway with an additional 12-feet of pavement widening beyond the centerline of the roadway with
a 3-foot wide gravel shoulder and borrow ditch sized to accommodate the roadway storm runoff on
the east side of the roadway.
Dedicate right-of-way to extend to 2-feet behind back of sidewalk on the west side and to 2-feet
behind back of borrow ditch on the east side.
If Sublimity Avenue is under construction when Skyranch moves forward, then no improvements to
Sublimity Avenue are required.
3. Provide written documentation allowing the closure of Tarrega Lane.
Prior to plan approval and ACHD's signature on the final plat which would close the private road,
relocate the proposed location of stub street, Street Q, to align with the existing location of Tarrega
Lane at the site's north property line or provide written documentation that Street Q can be stubbed
to the north, in its proposed location, and that all 6 parcels who use Tarrega Lane will have access
to Street Q.
If the applicant is unable to remove the private road, then Tarrega Lane should remain within the
site to allow access to the existing 6 residential parcels located north of the site.
4. Construct the entry portion of Street A with two 21-foot wide travel lanes, a 10-foot wide center
landscape median, curb, gutter and 5-foot wide attached concrete sidewalk.

located 1,238-feet east of SH-69.
15. Construct Street A, a local roadway, to intersect Sublimity Avenue, a collector roadway, proposed
to be constructed as part of ACHD's approval of Apex West Subdivision, located 330-feet north of
Lake Hazel Road. If Sublimity Avenue has not been constructed, stub Street A to the east.
16. Construct Street F, a local roadway, to intersect Street H, a local roadway, located 140-feet west of
Street J.
17. Construct Street D and Street P to align or offset any other local streets a minimum of 125-feet.
18. Construct the remaining internal local streets to align or offset a minimum of 125-feet.
19. Stub Street N to the north, located 459-east of SH-69.
20. Stub Street P to the east, located in alignment with or offset from any other local streets a minimum
of 125-feet.

to be constructed from either Street F, H, or K towards the Rawson Canal to provide access to one
of the Willeman parcels (parcel No. S1131336156 or S1131336111). Locate the stub street to allow
for the future construction of a bridge crossing; the proposed location will be evaluated for
constructability by ACHD staff. Submit a preliminary location for the stub street to ACHD for
approval prior to plan submittal. Additional easements may be required to accommodate the
construction of the stub street and bridge.
If the future stub street connection is required by the City of Meridian to be a public roadway, a road
trust deposit for half the bridge construction should be required; the actual amount of the road trust
deposit will be determined during the plan review process. If the City of Meridian approves the future
stub street connection as a private roadway, a road trust deposit for half the bridge construction
should not be required.
22. Install a sign at the terminus of each stub street stating that, "THIS ROAD WILL BE EXTENDED IN
THE FUTURE".
23. Construct seven 20-foot wide shared access driveways onto local streets within the site, as
proposed. The driveways shall be constructed as paved as curb cut type driveways.
24. Construct a 20-foot wide shared access driveway onto Street F, located a minimum of 75-feet from
the intersection of Street F and Street G. Construct the driveway as a paved curb cut type driveway.
25. Redesign Street F, Street H, Street K and Street M to reduce the length of the roadways or to
include the use of passive design elements and submit a revised preliminary plat showing the
4 Skyranch / MPP24-0012/ H-2024-0022
redesigned roadways for review and approval prior to plan approval and ACHD's signature on the
first final plat.
Speed humps/bumps and valley gutters will not be accepted as traffic calming.
26. 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.
27. Submit civil plans to ACHD Development Services for review and approval. The impact fee
assessment will not be released until the civil plans are approved by ACHD.
28. 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.
29. Comply with all Standard Conditions of Approval.

D. Findings for Consideration
1. Maximum Traffic on One Access
a. Applicant's Proposal: The applicant is proposing to construct only one access point to this
site and a secondary access point is proposed to be constructed as part of a future phase of
the development. The applicant is proposing to construct three stub streets to the adjacent
parcels.
Staff Comments/Recommendations: ACHD policy limits developments with only one access
point to 1,000 trips per day for local streets. The entrance roadway is anticipated to exceed
ACHD's allowed maximum forecast ADT of 1,000. Therefore, staff recommends the applicant
should be required to construct the secondary access point prior to ACHD's signature on the
final plat that contains the 100th lot. Or, as an alternative, the applicant may stop final platting
until the secondary public street access is available.
2. State Highway SH-69/Meridian Road
SH-69/Meridian Road 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-69/Meridian Road.
3. Lake Hazel Road
a. Existing Conditions: Lake Hazel Road is currently under construction as a 5-lane roadway
with vertical curb, gutter, a 10-foot wide multi use pathway and either a 4-foot wide buffer or an
8-foot wide landscape strip abutting the site. There is 75 to 145-feet of right-of-way for Lake
Hazel Road (50 to 67-feet from centerline).
b. Applicant's Proposal: The applicant is not proposing any street improvements to Lake Hazel
Road abutting the site.
c. Staff Comments/Recommendations: Lake Hazel Road will be fully improved; therefore, no
additional dedication of right-of-way or street improvements should be required as part of this
application.
4. North/South Mid Mile Collector — Sublimity Avenue
a. Existing Conditions: There is no north/south collector abutting the site.
b. Applicant's Proposal: The applicant is not proposing to construct a north/south mid-mile
collector abutting the site.
c. Staff Comments/Recommendations: ACHD's MSM identified a new north/south mid-mile
residential collector roadway abutting the site's east property line. This collector was also
identified and proposed to be fully constructed as part of the Apex West Subdivision located
directly east of the site.
The applicant of Apex West Subdivision, Brighton Development, has received plan approval to
allow for the construction of the north/south collector, however, construction has not begun.
The approved plans show Sublimity Avenue abutting the site's east property line, to be
constructed as a full street section with two 21-foot wide travel lanes, one center landscape
island, vertical curb, gutter, an 8-foot wide landscape strip and 5-foot wide detached concrete
sidewalks.
If Skyranch moves forward prior to the construction of Sublimity Avenue, then the applicant
should be required to stub Street A to the adjacent parcel to the east until Sublimity is
constructed by Brighton Development (see Finding 8.c. for stub street requirements).
OR
8 Skyranch / MPP24-0012/ H-2024-0022
The applicant may construct Sublimity Avenue, consistent with the MSM, as '/2 of a 36-foot wide
collector street section with vertical curb, gutter and 5-foot wide detached or 7-foot wide
attached concrete sidewalk abutting the site's east property line, with 12 additional feet of
pavement widening (30-feet of total pavement) beyond the centerline of the roadway with a 3-
foot wide gravel shoulder and borrow ditch sized to accommodate the roadway storm runoff on
the east side of the roadway across from the site. The right-of-way should extend a minimum of
2-feet behind back of curb for a detached sidewalk or the back of sidewalk for an attached
sidewalk on the west side and to 2-feet behind back of borrow ditch on the east side of the
roadway.
5. Private Road — Tarrega Lane
a. Existing Conditions: There is an existing paved private road, Tarrega Lane, located 1,825-
feet east of SH-69 that runs north from Lake Hazel Road through the site to provide access to
6 parcels.

b. Applicant's Proposal: The applicant is proposing to close the existing private road, Tarrega
Lane, at Lake Hazel Road incorporating it into the site and is proposing a stub street, Street Q,
to provide access to only 1 of the 6 parcels.
c. Staff Comments/Recommendations: During the pre-application process, staff requested that
applicant provide documentation to demonstrate that they have the ability to terminate the
existing easement for Tarrega Lane, however, this documentation was not provided. The
applicant should be required to provide written documentation allowing the closure of Tarrega
Lane.
Prior to plan approval and ACHD's signature on the final plat which would close the private road,
the applicant should be required to relocate the proposed location of stub street, Street Q, to
align with the existing location of Tarrega Lane at the site's north property line or provide written
documentation that Street Q can be stubbed to the north, in its proposed location, and that all
6 parcels who use Tarrega Lane will have access to Street Q.
If the applicant is unable to remove the private road, Tarrega Lane, then it should remain to
allow access to the existing 6 residential homes located north of the site.
9 Skyranch / MPP24-0012/ H-2024-0022
6. Internal Local Streets
a. Existing Conditions: There are no local public streets within the site.
b. Applicant's Proposal: The applicant is proposing to construct the entry portion of Street A with
two 21-foot wide travel lanes, a 10-foot wide center landscape median, curb, gutter and 5-foot
wide attached concrete sidewalk (shown in blue).
The applicant is proposing to construct the entry portion of Street G to intersect Lake Hazel
Road as a 3-lane, 47-foot wide local street section with curb, gutter and 5-foot wide attached
concrete sidewalk (shown in yellow).
The applicant is proposing to construct a portion of Street F as a 36-foot wide collector street
section with curb, gutter, an 8-foot wide landscape strip, 5-foot wide detached concrete sidewalk
within 40-feet of right-of-way (show in green).
The applicant is proposing to construct thirteen internal local streets as 27-foot wide local street
sections with curb, gutter and 5-foot wide attached concrete sidewalk (shown in orange).
The applicant is proposing to construct three internal local streets as 27-foot wide local street
sections with curb, gutter, 5-foot wide attached concrete sidewalks on one side and an 8-foot
wide landscape strip with 5-foot wide detached concrete sidewalk on the other side, located as
follows (shown in pink).
The applicant is proposing to construct a cul-de-sac turnaround at the terminus of Street H.

Staff Comments/Recommendations: The applicant's proposal for Street A, Street B north of
Street A, Street C, Street E east of Street D, Street G, Street H east of Street J, Street K east
of Street H, Street K west of Street N, Street L, Street M and Street O meet District policy and
should be approved as proposed.
Parking is restricted on one side of the 27-foot wide street sections (Street B north of Street A,
Street C, Street E east of Street D, Street H east of Street J, Street K east of Street H, Street K
west of Street N, Street L, Street M, and Street O). The applicant should be required to install
"NO PARKING" signs on one side of the streets. Coordinate a signage program with
10 Skyranch / MPP24-0012/ H-2024-0022
Development Review staff. The applicant should be required to provide written fire department
approval for the reduced street sections.
The applicant should be required to plat the center landscape medians on Street A as right-of-
way owned by ACHD. The applicant or future home-owners association should enter into a
license agreement with ACHD if landscaping is desired within the island.
The applicant should be required to construct the proposed cul-de-sac at the terminus of
Street H with a minimum turning radius of 50-feet. Staff recommends the applicant dedicates
right-of-way at the cul-de-sac turnaround be extended to touch Lot 40 of Block 5 to ensure
that the lot has access to Street H in the future.
The applicant's proposal to construct a portion of Street F as a 36-foot wide collector street
section meets District policy; however, staff recommends this portion of Street F to be
constructed as a local street as it is not anticipated to exceed ACHD's allowable average daily
trip threshold as a local street.
Street G is proposed to intersect Lake Hazel Road at the 1/4 mile east of Meridian Road/SH-
69. The street approach is being constructed as part of a Cooperative Development Agreement
project to widen Lake Hazel Road to 5 lanes between Meridian Road/SH-69 and Locust Grove
Road. A large mixed use development is currently in the early pre-application stages of the
development process and their traffic impact study will include an evaluation for a signal warrant
at the Street G/Lake Hazel Road intersection.
If warranted and approved as part of a future development application the following streets are
recommended to be constructed as 33-foot wide local street sections with curb, gutter and
minimum 5-foot wide concrete sidewalks: Street N, Street K east of Street N to Street H, Street
H from Street K to Street J, Street P, Street J south of Street P, Street F from Street A to Street
G, Street Q, and Street D as they are proposed to stub to adjacent parcels or they provide a
direct route to Street G which may potentially be signalized in the future (pending review of a
traffic impact study and future development application). ACHD policy does not allow the use
of a 27-foot wide street section for new roadway that exceed 1,000 trips per day or that may
exceed 1,000 trips per day once extended (stub streets). Staff recommendation shown on visual
below.

The applicant should be required to dedicate right-of-way to 2-feet behind back of sidewalk, or
for detached sidewalk, the applicant may reduce the right-of-way to 2-feet behind back of curb
and provide a permanent right-of-way easement from the right-of-way line to 2-feet behind back
of sidewalk.
7. Roadway Offsets
a. Existing Conditions: There are no roadways within the site.
b. Applicant's Proposal: The applicant is proposing to construct Street G, a local roadway, to
intersect Lake Hazel Road, a principal arterial roadway, located 1,238-feet east of SH-69.
The applicant is proposing to construct Street A, a local roadway, to intersect Sublimity Avenue,
a collector roadway, proposed to be constructed as part of ACHD's approval of Apex West
Subdivision, located 330-feet north of Lake Hazel Road.
The applicant is proposing to construct Street F, a collector roadway, to intersect Street H, a
local roadway, located 140-feet west of Street J.
The applicant is proposing to construct the remaining internal local streets to align or offset a
minimum of 125-feet with the exception of the two roadways located as follows:
• Street D, located 98-feet east of Street Q
• Street P, located 87-feet south of Street M
c. Staff Comments/Recommendations: The applicant's proposal to construct Street G to
intersect Lake Hazel Road does not meet District Local Street Intersection Spacing on Principal
Arterials policy which requires local streets to intersect a principal arterial with an offset of 1,320-
feet from all other existing roadways. However, the location of the roadway should be approved
as proposed, as the right-of-way for the approach was recently dedicated and the approach is
currently under construction as part of the Lake Hazel Road project.
The applicant's proposal to construct Street A to intersect Sublimity Avenue meets District policy
and should be approved, as proposed.
The applicant's proposal to construct Street F to intersect Street H does not meet District
Collector Offset policy which requires a 330-foot offset from Street J and should not be
approved, as proposed. However, as noted in Finding 6.c., staff recommends the applicant
construct Street F as a local street. Therefore, the applicant's proposal to construct Street F to
intersect Street H, located 140-feet west of Street J meets District Local Offset policy and should
be approved, as proposed.
The applicant's proposal to construct Street D and Street P with an offset less than 125-feet
from any other local streets does not meet District Local Offset policy and should not be
approved as proposed. The applicant should be required to construct Street D and Street P to
align or offset any other local streets a minimum of 125-feet.
The applicant's proposal to construct the remaining internal local streets to align or offset a
minimum of 125-feet meets District policy and should be approved, as proposed.
8. Stub Streets
a. Existing Conditions: There are no stub streets to or from the site.
b. Applicant Proposal: The applicant is proposing to construct three local stub streets, located
as follows (measured centerline-to-centerline):
• One stub street to the north, Street N, located 459-feet east of SH-69
12 Skyranch / MPP24-0012/ H-2024-0022
• One stub street to the east, Street P, located 1,125-feet north of Lake Hazel Road and
87-feet south of proposed Street M.
• One stub street to the north, Street Q, located 1,773-feet east of SH-69 and 98-feet west
of proposed Street D.
c. Staff Comments/Recommendations: The applicant's proposal for Street N meets District
policy and should be approved, as proposed.
The applicant's proposal for Street P meets District policy, with the exception of District Local
Offset policy. Upon meeting District Local Offset policy requirements (see Finding 7.c.), the
applicant's proposal should be approved.
The applicant's proposal to stub Street Q to the site's north property line, located 1,773-feet
east of SH-69, meets District policy; however, the proposed stub street location provides
access to only one of the six parcels who currently use Tarrega Lane, a private road, to
access their properties. Street Q is offset from the existing location of Tarrega Lane. Because
of this, Street Q should be relocated to align with the existing location of Tarrega Lane at the
site's north property line or provide written documentation that that Street Q can be stubbed to
the north as proposed and that all 6 parcels who use Tarrega Lane will have access to Street
Q. If Tarrega Lane is required to remain within the site (see Finding 5.c.), then Street Q may
remain in its proposed location, stubbing to the site's north property line.
Staff recommends that an access easement or a permanent right-of-way easement to allow
for the future construction of a stub street constructed from either Street F, H, or K towards the
Rawson Canal to provide access to one of the Willeman parcels (parcel No. S1131336156 or
S1131336111). The stub street should be in a location that will allow for the future
construction of a bridge crossing; the proposed location will be evaluated for constructability
by ACHD staff. The applicant should be required to submit a preliminary location for the stub
street to ACHD for approval prior to plan submittal. Additional easements may be required to
ensure that the stub street and bridge crossing can be constructed.
If the future stub street connection is required by the City of Meridian to be a public roadway, a
road trust deposit for half the bridge construction should be required, as the site's parcel line
extends to the centerline of the canal; the actual amount of the road trust deposit will be
determined during the plan review process. If the City of Meridian approves the future stub
street connection as a private roadway, a road trust deposit for half the bridge construction
should not be required.
If Skyranch moves forward prior to the construction of Sublimity Avenue, then the applicant
should be required to stub Street A to the adjacent parcel to the east, located 330-feet north of
Lake Hazel Road, until Sublimity is constructed by Brighton Development.
The applicant should be required to install a sign at the terminus of each stub street stating
that, "THIS ROAD WILL BE EXTENDED IN THE FUTURE".
9. Driveways
9.1 Internal Local Streets
a. Existing Conditions: There are no local streets constructed within the site.
b. Applicant's Proposal: The applicant is proposing to construct eight 20-foot wide shared
access driveways internal to the site.
c. Staff Comments/Recommendations: The applicant's proposal meets District policy and
should be approved, with the exception of the driveway onto Street F, located 67-feet west of
Street G (measured centerline-to-centerline). As noted in Finding 6.c., the applicant should be
required to construct Street F as a local street; therefore, any proposed driveways onto Street
13 Skyranch / MPP24-0012/ H-2024-0022
F should be required to meet District Local Driveway policies. Consistent with District Local
Driveway Location policy, the applicant should be required to construct the driveway onto Street
F, located a minimum of 75-feet from the intersection of Street F and Street G.
The driveways should be constructed as paved, curb cut type driveways.
10. Traffic Calming
a. Applicant's Proposal: The applicant is proposing to construct Street F, Street H, Street K and
Street M greater than 750-feet in length.
b. Staff Comments/Recommendations: The applicant should be required to redesign the above
listed roadways to reduce the length of the roadways or to include the use of passive design
elements and submit a revised preliminary plat showing the redesigned roadways for review
and approval prior to plan approval and ACHD's signature on the first final plat.
Speed humps/bumps and valley gutters will not be accepted as traffic calming.
11. Other Access
Lake Hazel Road is classified as a principal arterial roadway, Sublimity Avenue is classified as a
collector roadway. 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.
14 Skyranch / MPP24-0012/ H-2024-0022
E. Policy
1. Federal Accessibility Design Guidelines and Standards
District policy 7203.1.1 states that developers shall follow the current version of the U.S. Access
Board's Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way(PROWAG), 36
CFR Part 1190, September 7, 2023; (Also see, https//www.access-board.gov/prowag and
https//www.access-board.gov/files/prowag/planning-and-design-for-alternatives.pdf for additional
information).
2. Minor Improvements
Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing
Highways adjacent to a proposed development may be required. These needed transportation
facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or
bike lane construction or replacement (with physical buffers if missing and needed); construction of
transitional sidewalk segments; crosswalk construction or replacement; curb and gutter
construction or replacement; repair, replacement or expansion of curb extensions; replacement of
unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation
features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle,
pedestrian and bicycle traffic control devices; and other similar items. The current version of
PROWAG will determine the applicable accessibility requirements for alterations and elements
added to existing streets. ACHD staff is responsible for identifying the minor improvements that
would be proportionate to the size and complexity of the development.
3. Livable Street Performance Measures
District policy 7203.8 states that ACHD has adopted performance measures (level of stress) for
evaluating the experience of bicyclists and pedestrians. ACHD seeks to create a transportation
network that serves all ages and abilities. Bike and pedestrian facilities built through development
should achieve a bike and pedestrian level of traffic stress 1 or 2, with no new bike lane below a
minimum of 5-feet.
4. Lake Hazel 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
15 Skyranch / MPP24-0012/ H-2024-0022
fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the
Impact Fee Service Area.
No compensation will be provided for right-of-way on an arterial that is not listed as impact fee
eligible in the Capital Improvements Plan.
The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor
for future capacity improvements, as provided in Section 7300.
Pedestrian Facilities: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide are
required on both sides of all arterial streets. A parkway strip at least 8-feet wide between the back-
of-curb and street edge of the sidewalk is required to provide increased safety and protection of
pedestrians. Alternatively, on roadways identified for improvement in the Capital Improvement Plan,
a minimum 10-foot wide multi-use path may be required. The path shall be placed in accordance
with planned buildout in the Master Street Map with a minimum 8-foot wide planter strip as
measured to the closest edge of the path. Street trees are encouraged between the pedestrian
facility and the roadway when irrigation and maintenance will occur by the adjacent property owner
or HOA through an approved license agreement. Consult the District's planter width policy if trees
are to be placed within the parkway strip. In some instances, to match existing conditions, a
minimum 7-foot wide sidewalk may be constructed next to the back-of-curb. ACHD Development
Review staff will be responsible for determining the required facility. Vertical hardscape alternatives
to street trees may be considered in the buffer space when street trees are not practicable.
Detached sidewalks and multi-use paths are encouraged and should be parallel to the adjacent
roadway. Pedestrian facilities will only be allowed to deviate from a straight line parallel to the
roadway when authorized by Development Review staff to accommodate site specific conditions
(i.e., street trees, utilities, etc.).
Appropriate easements shall be provided if public pedestrian facilities are placed out of the right-of-
way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind
the back edge of the pedestrian facility. Pedestrian facilities shall either be located wholly within the
public right-of-way or wholly within an easement.
Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each
pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable
warning surface in accordance with the current version of PROWAG.
Frontage Improvements Policy: District Policy 7205.2.1 states that the developer shall widen the
pavement to a minimum of 17-feet from centerline plus a 3-foot wide gravel shoulder adjacent to
the entire site. Curb, gutter and additional pavement widening may be required (See Section
7205.5.5).
ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM)
guide the right-of-way acquisition, arterial street requirements, and specific roadway features
required through development. This segment of Lake Hazel Road is designated in the MSM as a
Residential Arterial with 5-lanes, multi-use pathways and a 59-foot street section within 99-feet of
right-of-way.
5. Sublimity 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
16 Skyranch / MPP24-0012/ H-2024-0022
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.
Half Street Policy: District Policy 7206.2.2 required improvements shall consist of pavement
widening to one-half the required width, including curb, gutter and concrete sidewalk (minimum 5-
feet), 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. 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 top 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: 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.
17 Skyranch / MPP24-0012/ H-2024-0022
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 Residential Collector. The Residential Collector typology as depicted in the Livable
Street Design Guide recommends a 2-lane roadway with bike lanes, and on street parking, a 36-
foot street section within 50 to 70-feet of right-of-way.
6. Maximum Traffic on One Access
District policy 7207.3.3 states that if a proposed development only has one access to a public street
that is a local street, or if it proposes to extend public streets from existing development with only
one local street access to the public street system, the maximum forecast ADT to be allowed at any
point on the local street access is 1,000 and is subject to fire department requirements for the
provision of a secondary access. This volume may be reduced or increased based on information
received from the lead land use agency, the applicable fire department, and/or emergency services.
The District will also take into consideration the following items when determining whether or not to
reduce or increase the maximum allowable ADT: railroad crossings, canal crossings, topography
(foothills vs. flat land), pedestrian connectivity, location of schools, etc.
7. Average Daily Traffic (ADT)
District policy 7207.3.1 states that ADT on new and existing local streets should typically be less
than 2,000. This ADT applies to both existing and new streets. For new streets that are stubbed
to connect to adjacent land that is not fully developed, the allowable ADT for the new street will
typically be no more than 1,000 ADT, to accommodate future additional traffic from the adjacent
land, depending on the size of the adjacent undeveloped land. When stub streets are connected
and properties fully developed, local streets should not exceed 2,000.
In developed areas where streets already exceed 2,000 ADT or are close to exceeding 2,000 ADT,
the Commission may grant approval to exceed 2,000 ADT based on existing zoning of undeveloped
properties or infill development. The Commission may also consider the need for additional
roadway improvements or traffic calming to mitigate the additional traffic if necessary.
The ADTs listed above are desirable planning thresholds for local streets, not roadway capacities.
Actual roadway capacities are much higher than the planning thresholds.
8. Internal Local 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
18 Skyranch / MPP24-0012/ H-2024-0022
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
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
Reduced Urban Local Street-27-foot Street Section and Right-of-Way Policy: District Policy
7207.5.2 states that the width of a reduced urban local street shall be 27-feet (back-of-curb to back-
of-curb) with curb, gutter, and minimum 5-foot concrete sidewalks on both sides and shall typically
be within 41-feet of right-of-way. Unless approved in writing by the land use agency, this street
section is not allowed by the City of Kuna and City of Star. In some cases, this street width may not
accommodate new utilities. A 29-foot street section within 43-feet of right-of-way may be
constructed in lieu of a 27-foot street section if the applicant demonstrates that the additional
roadway width is necessary to extend the utilities. Although some parking is allowed by the following
subsections, the District will further restrict parking on a reduced width street if curves or other
physical features cause problems, if actual emergency response experience indicates that
emergency vehicles may not be able to provide service, or if other safety concerns arise. One of
the following three sets of design conditions shall apply.
Design Condition #1: Parking is allowed on one side of a reduced width street when all of the
following criteria are met:
• The street is in a residential area.
• The developer shall provide written approval from the appropriate fire department or
emergency response unit in the jurisdiction.
• The developer shall install NO PARKING signs on one side of the street, as specified by the
District and as specified by the appropriate fire department.
• This street section shall include curb, gutter, and minimum 5-foot wide concrete sidewalks
on both sides and shall typically be constructed within 41-feet of right-of-way.
• Traffic volumes on the street shall not exceed 1,000 vehicle trips per day. There shall be no
possibility that another street may be connected to it in a manner that would allow more than
1,000 vehicle trips per day.
Sidewalk Policy: District Policy 7207.5.7 states that five-foot wide concrete sidewalk is required
on both sides of all local streets, 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.
19 Skyranch / MPP24-0012/ H-2024-0022
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.
Landscape Medians Policy: District policy 7207.5.16 states that landscape medians are
permissible where adequate pavement width is provided on each side of the median to
accommodate the travel lanes and where the following is provided:
• The median is platted as right-of-way owned by ACHD.
• The width of an island near an intersection is 12-feet maximum for a minimum distance of
150-feet. Beyond the 150-feet, the island may increase to a maximum width of 30-feet.
• At an intersection that is signalized or is to be signalized in the future, the median width shall
be reduced to accommodate the necessary turn lane storage and tapers.
• The Developer or Homeowners Association shall apply for a license agreement if
landscaping is to be placed within these medians.
• The license agreement shall contain the District's requirements of the developer including,
but not limited to, a"hold harmless" clause; requirements for maintenance by the developer;
liability insurance requirements; and restrictions.
• Vertical curbs are required around the perimeter of any raised median. Gutters shall slope
away from the curb to prevent ponding.
9. Roadway Offsets
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).
Local Offset Policy: District policy 7207.4.2, requires local roadways to align or provide a minimum
offset of 125-feet from any other street (measured centerline to centerline).
20 Skyranch / MPP24-0012/ H-2024-0022
District policy 7208.4.2, requires commercial roadways intersecting other local streets (residential,
industrial or commercial) to provide a minimum offset of 125-feet from any other roadway or
intersection (measured centerline to centerline).
District policy 7209.4.2, requires industrial roadways intersecting other local streets (residential,
industrial or commercial) to provide a minimum offset of 125-feet from any other roadway or
intersection (measured centerline to centerline).
10. Stub Streets
Stub Street Policy: District policy 7207.2.4.3 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 7207.2.4, 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 ROAD WILL BE EXTENDED 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.
11. Driveways
11.1 Internal Local Streets
Driveway Location Policy: District policy 7207.4.1 requires driveways near intersections to be
located a minimum of 75-feet (measured centerline-to-centerline) from the nearest local street
intersection, and 150-feet from the nearest collector or arterial street intersection.
Successive Driveways: District Policy 7207.4.1 states that successive driveways away from an
intersection shall have no minimum spacing requirements for access points along a local street, but
the District does encourage shared access points where appropriate.
Driveway Width Policy: District policy 7207.4.3 states that where vertical curbs are required,
residential driveways shall be restricted to a maximum width of 20-feet and may be constructed as
curb-cut type driveways.
Driveway Paving Policy: Graveled driveways abutting public streets create maintenance
problems due to gravel being tracked onto the roadway. In accordance with District policy,
7207.4.3, 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.
12. Traffic Calming
Speed Control and Traffic Calming Policy: District policy 7207.3.7 states that the design of local
street systems should discourage excessive speeds by using passive design elements. If the
design or layout of a development is anticipated to necessitate future traffic calming implementation
by the District, then the District will require changes to the layout and/or the addition of passive
design elements such as horizontal curves, bulb-outs, chokers, etc. The District will also consider
texture changes to the roadway surface (i.e. stamped concrete) as a passive design element.
These alternative methods may require maintenance and/or license agreement.
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.
21 Skyranch / MPP24-0012/ H-2024-0022
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.
15. 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.
F. Standard Conditions of Approval
1. All proposed irrigation facilities shall be located outside of the ACHD right-of-way (including all
easements). Any existing irrigation facilities shall be relocated outside of the ACHD right-of-way
(including all easements).
2. Private Utilities including sewer or water systems are prohibited from being located within the ACHD
right-of-way.
3. In accordance with District policy, 7203.3, the applicant may be required to update any existing non-
compliant pedestrian improvements abutting the site to meet current Americans with Disabilities
Act (ADA), Public Right-of-Way Accessibility Guidelines (PROWAG), ISPWC, or ACHD
requirements . The applicant's engineer should provide documentation of compliance to District
Development Review staff for review.
4. Replace any existing damaged curb, gutter and sidewalk and any that may be damaged during the
construction of the proposed development. Contact Construction Services at 387-6280 (with file
number) for details.
5. A license agreement and compliance with the District's Tree Planter policy is required for all
landscaping proposed within ACHD right-of-way or easement areas.
6. All utility relocation costs associated with improving street frontages abutting the site shall be borne
by the developer.
7. It is the responsibility of the applicant to verify all existing utilities within the right-of-way. The
applicant at no cost to ACHD shall repair existing utilities damaged by the applicant. The applicant
shall be required to call DIGLINE (1-811-342-1585) at least two full business days prior to breaking
ground within ACHD right-of-way. The applicant shall contact ACHD Traffic Operations 387-6190
in the event any ACHD conduits (spare or filled)are compromised during any phase of construction.
