7 Addison Circle /
MPP24-0016/ H-2024-0040
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. Black Cat 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
8 Addison Circle /
MPP24-0016/ H-2024-0040
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 Black Cat Road is designated in the MSM as a
Residential Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within 100-feet of
right-of-way.
5. Torana Street
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).
9 Addison Circle /
MPP24-0016 / H-2024-0040
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
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.
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.
6. Tree Planters
Tree Planter Policy: Tree Planter Policy: The District's Tree Planter Policy prohibits all trees in
planters less than 8-feet in width without the installation of root barriers. Class II trees may be
allowed in planters with a minimum width of 8-feet, and Class I and Class III trees may be allowed
in planters with a minimum width of 10-feet.
7. Landscaping
Landscaping Policy: A license agreement is required for all landscaping proposed within ACHD
right-of-way or easement areas. Trees shall be located no closer than 10-feet from all public storm
drain facilities. Landscaping should be designed to eliminate site obstructions in the vision triangle
at intersections. District Policy 5104.3.1 requires a 40-foot vision triangle and a 3-foot height
10 Addison Circle /
MPP24-0016/ H-2024-0040
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.
8. Pathway Crossings: United States Access Board R304.5.1.2 Shared Use Paths. In shared use
paths, the width of curb ramps runs and blended transitions shall be equal to the width of the shared
use path.
AASHTO's Guidelines for the Development of Bicycle Facilities 5.3.5 Other Intersection
Treatments: The opening of a shared use path at the roadway should be at least the same width
as the shared use path itself. If a curb ramp is provided, the ramp should be the full width of the
path, not including any flared sides if utilized. . . . Detectable warnings should be placed across the
full width of the ramp.
FHWA's "Designing Sidewalks and Trails for Access" (1999) reflected common ADA-related
concepts: Chapter 6, Page 16-6: The width of the ramp should be at least as wide as the average
width of the trail to improve safety for users who will be traveling at various speeds. In addition, the
overall width of the trail should be increased, so the curb ramp can be slightly offset to the side.
The increased width reduces conflict at the intersection by providing more space for users at the
bottom of the ramp.
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.
8. Utility street cuts in pavement less than five years old are not allowed unless approved in writing by
the District. Contact the District's Utility Coordinator at 387-6258 (with file numbers) for details.
9. All design and construction shall be in accordance with the ACHD Policy Manual, ISPWC Standards
and approved supplements, Construction Services procedures and all applicable ACHD Standards
unless specifically waived herein. An engineer registered in the State of Idaho shall prepare and
certify all improvement plans.
11 Addison Circle /
MPP24-0016/ H-2024-0040
10. Construction, use and property development shall be in conformance with all applicable
requirements of ACHD prior to District approval for occupancy.
11. No change in the terms and conditions of this approval shall be valid unless they are in writing and
signed by the applicant or the applicant's authorized representative and an authorized
representative of ACHD. The burden shall be upon the applicant to obtain written confirmation of
any change from ACHD.
12. If the site plan or use should change in the future, ACHD Planning Review will review the site plan
and may require additional improvements to the transportation system at that time. Any change in
the planned use of the property, which is the subject of this application, shall require the applicant
to comply with ACHD Policy and Standard Conditions of Approval in place at that time unless a
waiver/variance of the requirements or other legal relief is granted by the ACHD Commission.
G. Conclusions of Law
1. The proposed site plan is approved, if all of the Site Specific and Standard Conditions of Approval
are satisfied.
2. ACHD requirements are intended to assure that the proposed use/development will not place an
undue burden on the existing vehicular transportation system within the vicinity impacted by the
proposed development.
