(A) Design
& Construction.
Alleys shall be designed and constructed
according to the City’s Technical Standards Manual.
(B) Alleys
Required.
Alleys are required for all residential subdivisions
of two (2) or more lots.
(C) Waiver.
The Director of Engineering may authorize an Alley Waiver only for a subdivision having four or fewer lots, or the Plan Commission may authorize a Development Variance (in accordance with Article 1, Division
4 in Chapter
5 of this GDC) to the requirement for alleys. The requirement for alleys may be waived or varied only if each of the following conditions are met:
(1) A minimum ten-foot wide utility easement (or other size, as determined by the Director of Engineering or by the applicable utility provider) is provided on each lot adjacent to the street right-of-way, in accordance with Chapter
5, Article 1, Division
4 of this GDC;
(2) No
lot-to-lot surface drainage exists or will result within the subdivision;
(3) The
subdivision design allows for an efficient solid waste collection
pattern;
(4) Adequate
area is dedicated for drainage facilities and utilities;
(5) Adequate
on- and off-street parking is provided; and
(6) Waiver
or variance from the requirement for alleys will not adversely affect
other properties.
(D) Alley
Width.
(1) Alleys
shall be not less than twenty feet in right-of-way width and paved
with reinforced concrete, in accordance with the City’s Technical
Standards.
(2) Additional
paving width shall be provided at all intersections and turns in the
alley alignment, per the Technical Standards. Curves or turns in alleys
shall be in accordance with the Technical Standards such that they
will accommodate turning movements of sanitation trucks, fire apparatus
and other large vehicles.
(E) Alley
Length.
Alleys may not exceed the maximum length set
forth in the City’s Technical Standards Manual, as measured
along the centerline of the alley and between intersections with other
alleys or entrances onto streets (at the right-of-way line of the
street at the alley entrance). A request for a Development Variance
of alley length may be considered based on the following:
(1) The
effect of alley length upon access, congestion, delivery of municipal
services, and upon convenience to residents of the subdivision in
accessing rear driveways and in driving around to the front of their
homes; and
(2) Means
of mitigation, including but not limited to additional mid-block alley
turnouts, limitation on the number of lots to be served along a single
alley segment, temporary points of access, and additional fire protection
measures.
(F) Alley
Design.
(1) Alley
intersections shall be perpendicular as described in the Technical
Standards Manual.
(2) Intersection
pavement design shall be of sufficient width and inside radius to
accommodate waste collection and emergency vehicles.
(3) Intersections
shall be three-way wherever possible, and four-way intersections are
prohibited. No alley intersection serving more than four directions
is allowed.
(G) Dead-End
Alleys.
(1) “Hammerhead”
alleys are prohibited. Alleys must have adequate turnouts and street
entrances such that vehicular traffic flow is continuous and efficient.
Where a temporary dead-end alley situation is unavoidable, a temporary
turnaround bulb or turnout onto a street, either of which will need
a temporary easement for street or alley purposes, shall be provided
as determined by the Director of Transportation. Pavement within the
easement must be constructed per the reinforced concrete alley section
as shown in the City’s Technical Standards.
(2) Permanent
dead-end alleys are prohibited.
(3) Four-way,
alley-to-alley intersections are prohibited.

Alleys Clean Upon Completion. After the
alleys are completed in a subdivision, debris or construction materials
of any nature shall not be placed in the alleys without written permission
of the Director of Engineering. Prior to Final Acceptance, the alleys
shall be swept clean of any dirt, debris, construction materials,
and foreign material.
