7 Pebblebrook/ MPP24-0003/
H-2024-0005
C. 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. Meridian 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 Policy 7205.2.1 & 7205.5.2 states that
the standard 3-lane street section shall be 37-feet (back-of-curb to back-of-curb). This width
typically accommodates a single travel lane in each direction, and a continuous center left-turn lane,
and curbs and gutters. A 3-lane road shall also include a minimum 10-foot wide multi-use path on
both sides with at 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 53-feet to allow for a 5-foot wide bike lane and 3-foot wide painted buffer.
Landscaped medians with intermittent turn lanes may be allowed when a minimum of 20-feet of
pavement on both sides of the median is provided.
8 Pebblebrook/ MPP24-0003/
H-2024-0005
If a landscaped median is included in any of these cross sections, the landscaping shall be
maintained by license agreement with the adjacent HOA, property owner, or by interagency
agreement with the corresponding land use jurisdiction.
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 pathway and buffers.
Right-of-Way Dedication: District Policy 7205.2 states that The District will provide compensation
for additional right-of-way dedicated beyond the existing right-of-way along arterials listed as impact
fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the
Impact Fee Service Area.
No compensation will be provided for right-of-way on an arterial that is not listed as impact fee
eligible in the Capital Improvements Plan.
The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor
for future capacity improvements, as provided in Section 7300.
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 Meridian Road is designated in the MSM as a
Residential Arterial with 3-lanes within 78-feet of right-of-way.

H-2024-0005
5. Internal Local Streets
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
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
10 Pebblebrook/ MPP24-0003/
H-2024-0005
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. Roadway Offsets
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).
7. 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.
Temporary Dead End Streets Policy: District policy 7207.2.4.4 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.
8. Driveways
8.1 Meridian Road
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 7205.4.6 states that direct access to minor 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 a under
11 Pebblebrook/ MPP24-0003/
H-2024-0005
District policy 7205.4.6, unless a waiver for the access point has been approved by the District
Commission.
Driveway Location Policy: District policy 7205.4.5 requires driveways located on minor arterial
roadways from a signalized intersection with a single left turn lane shall be located a minimum of
330-feet from the nearest intersection for a right-in/right-out only driveway and a minimum of 660-
feet from the intersection for a full-movement driveway.
District policy 7205.4.5 requires driveways located on minor arterial roadways from a signalized
intersection with a dual left turn lane shall be located a minimum of 330-feet from the nearest
intersection for a right-in/right-out only driveway and a minimum of 710-feet from the intersection
for a full-movement driveway.
Successive Driveways: District policy 7205.4.6 Table la, requires driveways located on minor
arterial roadways with a speed limit of 40 MPH to align or offset a minimum of 330-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.
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.
8.2 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.
9. 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

H-2024-0005
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.
10. 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.
11. 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.
12. 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.
