In response to your request for comment, the Ada County Highway District has reviewed the
submitted application and site plan for the item referenced above. It has been determined
that ACHD has site specific conditions of approval for this application.
A. Findings of Fact
1. North-South Street Section
a. Applicant’s Proposal: The applicant is proposing to construct the north-south
street section as a private street. The City of Meridian has requested that ACHD
allow the north-south street section to be a reduced public street section
(sidewalk on the west side only).
b. Staff Comments/Recommendations: The City of Meridian’s request to have
the applicant construct the north-south private street as a public street section
should be approved. ACHD will allow the north-south street section to be
constructed as a minor local (24-foot Street), or constructed as an alley per the
policy as follows:
c. Policy
Minor Urban Local Street (24-foot Street)
Minor Local Street Policy: District policy 7207.5.2 states that a minor local street is
defined as a reduced width local street that provides direct lot access for residential
uses, and in limited circumstances, commercial or mixed use as described below.
• Pavement Width and Curb Type: A minor local shall be constructed with a
reduced width of 24-feet from back-of-curb to back-of-curb with curb and gutter.
Where the minor local street is utilized in a gridded street system with alleys,
vertical curb shall be required and direct lot access shall be restricted. Where the
minor local street is utilized, with residential open space scenarios, rolled curb or
ribbon curbing (with an inverted crown), is allowed if access to the rear of the
parcels is provided from the minor local street.
• Sidewalk and Right-of-Way: Five-foot wide concrete sidewalks are required on
both sides, unless as otherwise described below or approved by ACHD and the
lead land use agency. The sidewalk for this street section may be located within a
permanent right-of-way easement. If the sidewalk is located within an easement,
the minimum right-of-way width for this street section is 28-feet, to allow for 2-feet
behind the back-of-curb on each side. Sidewalk may not be required, or may be
_____________________________________________________________________________________________________________
Ada County Highway District • 3775 Adams Street • Garden City, ID • 83714 • PH 208-387-6100 • FX 345-7650 • www.achdidaho.org
required on one side only as determined by the lead land use agency, if the minor
local street is used in residential areas where houses accessing the minor local
street are built with the front of the house (including the front door) facing the
common or open space lots that include a connected system of sidewalks or
paved pathways and the lotting pattern is mirrored on both sides of the street.
• Parking: Parking is prohibited on both sides of this street section. “No Parking”
signs are required. Alternative parking for guests, visitors, auxiliary residential
parking, and deliveries shall be provided and shall be designated and located in
coordination with the lead land use agency. Typically this parking will be provided
via community parking spaces located within walking distance of these types of
residences. Walking distance shall be defined by the lead land use agency.
• Requirements (This street section may only be used if the following conditions
are met):
The maximum projected ADT is less than 400.
The street connects to two other standard size streets.
There is support from the lead land use agency (either from staff or
Commission/ Council).
Maximum block length of 600-feet.
In commercial or mixed use areas where urban designs utilizing alleys are
desirable, but may be impractical due to access restrictions to classified
roadways (arterials, collectors, and residential collectors). In this example,
the minor local street would parallel the access-restricted roadway and
would provide direct access to the commercial or mixed-use lots.
No portion of a building shall be over 30-feet in height. If any portion of a
building is over 30-feet in height, aerial fire apparatus is required and a 26-
foot wide street is required (International Fire Code Appendix D Section
C105). However, a 26-foot wide street, with a minimum right-of-way of 30-
feet, is allowed if all other requirements for a minor local street are met.
Minor Improvements Policy: District Policy 7203.3 states that minor
improvements to existing streets adjacent to a proposed development may be
required. These improvements are to correct deficiencies or replace deteriorated
facilities. Included are sidewalk construction or replacement; curb and gutter
construction or replacement; replacement of unused driveways with curb, gutter
and sidewalk; installation or reconstruction of pedestrian ramps; pavement
repairs; signs; traffic control devices; and other similar items.
d. Policy
Alleys
New Alley Policy: District Policy 7210.3.1 requires the minimum right-of-way width
for all new residential alleys shall be a minimum of 16-feet or a maximum of 20-feet.
If the residential alley is 16-feet in width building setbacks required by the land use
agency having jurisdiction shall provide sufficient space for the safe backing of
vehicles into the alley (see Section 7210.3.3). The minimum right-of-way width for
all new commercial or mixed-use alleys shall be 20-feet. All alleys shall be
improved by paving the full width and length of the right-of-way.
Dedication of clear title to the right-of-way and the improvement of the alley, and
acceptance of the improvement by the District as meeting its construction
standards, are required for all alleys contained in a proposed development.
Alley Length Policy: District Policy 7210.3.2 states that alleys shall be no longer
than 700-feet in length. If the lead land use agency having jurisdiction requires a

shorter block length, the alley shall be no longer than the agency’s required block
length.
Alley Parking & Setbacks Policy: District Policy 7210.3.3 states that parking
within the alley right-of-way is prohibited. “No Parking” signs are required to be
installed by the developer. The signs should be located at the alley/street
intersections. Parking which is entered from the alley shall be designed so the
minimum clear distance from the back of the parking stall to the opposite side of the
alley is 20-feet for all perpendicular parking.
Setbacks for structures taking access from the alley should be closely coordinated
with the lead land use agency. The setbacks shall either discourage parking within
the alley (where it may partially block or occur within the right-of-way) or allow
adequate area for one perpendicular parking pad. In order to discourage parking,
building setbacks shall be minimal from the alley right-of-way line, while still
achieving the required 20-feet of back-up space from a garage or other parking
structure to the opposite side of the alley (i.e. 4-foot setback + 16-foot alley= 20-feet
for back-up space).
Alley Intersections and Offsets Policy: District policy 7210.3.7 states that alleys
should intersect public streets at each end. In specific circumstances as outlined in
the policies below, the District may consider allowing an alley to intersect a public
street at only one end. A 90-degree angle of intersection shall be designed where
practical. In no case shall the intersecting angle be less than 75-degrees, as
measured from centerline of intersecting street. An access to an alley shall be
located a minimum of 50-feet from the nearest street (as measured centerline to
centerline).
Alley/Alley Intersection Policy: District policy 7210.3.7.1 states that alley to alley
intersection may only be considered or allowed under the specific circumstances
identified below:
• The lead land use agency supports the land use proposing an alley to alley
intersection.
• The intersecting alleys provide access to residential uses. On a case by case
basis the District will consider allowing the alley to alley intersections for mixed
use areas within a development.
• For alley/alley intersections, base the sight triangle on the 10x20 and use
ACHD Policy 7200 Figure 3, but decrease the driver’s eye location to 10’ from
the edge of travel way.
• For the horizontal curves in an alley base the clear sight triangle on AASHTO
equation 3-38. HSO=R(1-cos(28.65*S/R)). The value for S shall be based on
a single vehicle approaching a nonmoving object at 15 mph.
• Appropriate radii and site distances are accommodated at the alley/alley
intersection. The minimum inside radius at the alley/alley intersection shall be
28-feet and the minimum outside radius shall be 48-feet. The radii at the
intersection shall accommodate the planned design vehicle, most typically a
sanitary services vehicle.
• The sight triangles shall either be identified as common spaces with
landscaping restrictions or permanent easements identified on the plat.
• A coordination meeting is held with the applicable agency staff (fire department,
police department, sanitary service provider, land use agency, and ACHD) to
discuss and resolve potential issues.
• The crossing alley has a maximum block length of 500-feet (measured near
edge to near edge of the intersecting streets). The crossing alley shall intersect

a public street at each end and shall not terminate at another alley. The
crossing alley is the alley that has intersections with two public streets and an
intersection with the perpendicular alley.
Alley/Local Street Intersections Policy: District Policy 7210.3.7.2 states that
alleys may intersect all types of local streets including minor local streets. Alleys
shall generally be designed with a curb cut type approach when intersecting a
local street. Alleys shall generally intersect streets in the middle of the block
equally offsetting the intersecting streets. Alleys shall either align with alley/street
intersections or provide a minimum 100-foot offset (measured centerline to
centerline) from other local street intersections. For alley intersections with local
streets, the District may consider a reduced offset if the lead land use agency’s
required lot size allows for shorter buildable lots.
2. East-West Street Section
a. Applicant’s Proposal: The applicant is proposing to construct the east-west
street section as a private street. The City of Meridian has requested that ACHD
allow the east-west private street to be a public alley.
b. Staff Comments/Recommendations: The City of Meridian’s Request to have
the east-west private street constructed as a public alley should be approved. The
alley policy listed above will be the requirements for the construction of the east-
west steet section as a public alley.
B. Site Specific Conditions of Approval
1. For the north-south street, the applicant may:
a. Construct the north-south street as a minor urban local street with a width of 24-
feet from back-of-curb to back-of-curb, with curb and gutter, within 28-feet of right-
of-way. The applicant should construct a five-foot wide concrete sidewalk on the
west side, located within a sidewalk eastement. “No Parking” signs shall be
installed.
OR
b. Construct the north-south street as a public alley that is 16-feet wide within 20-
feet or right-of-way. “No Parking” signs shall be installed.
2. Construct the east-west street as a public alley that is 16-feet wide within 20-feet of right-
of-way. “No Parking” signs shall be installed.
3. A Traffic Impact Fee will be assessed by ACHD and will be due prior to issuance of a
building permit. Please contact the ACHD Planner (see below) for information regarding
impact fees.
4. Plans shall be submitted to the ACHD Development Services Department for plans
acceptance, and impact fee assessment (if an assessment is applicable).
5. Comply with the Standard Conditions of Approval as noted below.
