[Amended 4-16-2009; 9-17-2015]
The purpose of this article is to establish the procedures,
design standards and maintenance obligations for roads that are not
intended to be dedicated to the public.
The procedures and standards of this article shall apply to
all private roads or shared driveways, including developments with
attached or detached dwelling units regulated by the Condominium Act
(Act 59 of 1978, MCLA § 559.101 et seq.).
The following items shall be provided to the Planning Department:
A.
Parcel numbers and the name of the owner for all properties having
legal interest in the private road.
B.
Plans, designed by a registered engineer or land surveyor, showing
location, dimension, and design of the private road. The plan shall
identify existing and proposed elevations for all areas to be disturbed
or altered by construction of the private road.
C.
A topographic survey on USGS datum at intervals of not more than
two feet.
D.
The minimum stopping and intersection sight distances shall meet
the criteria outlined in the American Association of State Highway
and Transportation Officials (AASHTO) Manual.
E.
The location, caliper size and species of all trees larger than eight
inches and located within the private road easement.
F.
The location of all public or private utilities located within the
private road easement and within 20 feet of the easement.
G.
The location of any lakes, streams, drainageways or wetlands within
100 feet of the proposed private road easement.
H.
A declaration of restriction for private road construction and maintenance
in a format acceptable to the Township.
A.
Recorded easements shall be established for the joint use of all
resultant parcels for the purposes of ingress, egress and private
or publicly owned utilities.
B.
Private road easements shall be 60 feet wide, except for private
roads serving four units or fewer, then the width of the easement
may be reduced to a minimum of 40 feet, provided all of the following
conditions exist:
(1)
The easement is unlikely to become a public street in the future.
(2)
The easement does not have the potential to serve additional
lots in the future.
(3)
A reduced easement width, between 40 and 59 feet, will result
in the preservation of natural features, including topography, woodlands
and common space.
(4)
The reduced easement width is adequate to accommodate required
pavement width, underground utilities, and required parking, required
turnaround, required pedestrian facilities, lighting and/or landscaping.
C.
Private roads serving four units or fewer shall meet the following
design standards:
D.
Private roads serving five units or more shall be designed to meet
Wayne County's typical residential road design standard.
E.
Culs-de-sac shall be designed to meet Wayne County's typical residential
cul-de-sac design standard.
F.
A private road shall provide a cul-de-sac turnaround or other configuration
approved by the Fire Department.
G.
The private road shall be set back a minimum of 15 feet from any
adjoining lot (excluding lots that are traversed by the access easement)
or parcel which does not derive access from the private road.
H.
All areas disturbed by the construction of a private road shall be
provided with topsoil, seeded with grass, and protected against erosion.
I.
Tree replacement shall be provided in accordance with Article 23, Tree and Woodlands Replacement.
J.
Fourteen feet of overhead tree clearance shall be provided for the
width of the road.
K.
Geometric standards.
(1)
Grades shall not exceed 7%, with a maximum grade of 2% for a
minimum distance of 30 feet from the intersection with a public right-of-way
or another private road. The Township may approve a grade of up to
10% for low-traffic-volume roads, provided that there are under 500
vehicles per day and where significant topographic features would
be preserved.
(2)
The minimum horizontal curve shall be defined by the desired
design speed but should never be less than a radius of 165 feet. A
minimum radius of 50 feet shall be provided for roads with a ninety-degree
turn.
(3)
Vertical curves shall be designed for grade changes greater
than 1%.
(4)
The minimum tangent distance (straightaway) between two curves
shall be 100 feet.
(5)
Minimum stopping and intersection sight distances shall meet
the design criteria contained in the most-recent edition of the American
Association of State Highway and Transportation Officials (AASHTO)
Manual, "A Policy on Geometric Design for Highways and Streets."
L.
Intersection design standards.
(1)
Private roads shall intersect an existing or proposed private
or public road at a ninety-degree angle and provide a radius of 50
feet. Where constrained by environmental features, a reduced angle
of intersection is permitted, provided the angle is greater than 80°.
M.
Road names are required for any private road serving two or more
lots. Proposed road names shall be submitted to the Township for approval.
N.
All signs within the private road easement shall be identified on
the site plan and be in accordance with the Michigan Manual of Uniform
Traffic Control Devices. Street signs shall be provided at all intersections.
These signs shall contrast with public street signs in terms of color
and shall indicate the road is private. The Township may require the
posting of no-parking signs.
O.
Sidewalks or bike paths are encouraged and may be required by the
Planning Commission.
For the purpose of this article, a "shared residential driveway"
is a driveway that provides vehicular access to two single-family
dwelling units or two primary residential buildings and shall comply
with the following standards:
A.
The shared driveway must be located within a recorded easement. The
minimum width of the easement is 25 feet, unless a wider easement
is required to adequately address drainage, as determined by the Township
Engineer.
B.
The driveway surface shall be at least 18 feet wide, measured edge
to edge, unless otherwise approved by the Township in consideration
of significant topographic, wetland or other natural features on the
site and provided the reduced drive width and easement is adequate
to serve existing and future underground utilities.
C.
The shared driveway shall be constructed of materials suitable to
accommodate emergency vehicles.
D.
Adequate sight distance shall be provided along the intersecting
road.
E.
A shared access easement and maintenance agreement is required for
all property owners that benefit from the shared residential driveway.
The agreement must clearly state that the drive may not serve additional
lots in the future unless upgraded to a private road, in accordance
with all applicable standards. The agreement shall be recorded with
Wayne County and a recorded copy provided to the Township prior to
approval of the private driveway.
Gates, functioning or ornamental, or any other structure intended
to restrict access are prohibited, except such structures are permitted
on roads with higher traffic volumes and for larger residential lots
which are not part of a uniform development and provided the following
standards are met:
A.
Properties shall be located along a major thoroughfare, be at least
three acres in size and have a minimum 250 feet of road frontage.
B.
Structures shall be set back a distance equal to the front yard setback
required for the zoning district.
C.
The height of the gate shall not exceed eight feet in height.
D.
The height of any support or decorative structures shall not exceed
10 feet, measured from the ground level to the highest part of the
structure.
E.
A landscape plan is required. Landscape shall be designed to obscure
the structure from the road and be integrated into an overall landscape
plan for the entire road frontage. A minimum of two trees and six
shrubs shall be provided for each 40 linear feet of road frontage.
F.
The gate shall not contain any barbed wire, electric current or charges
of electricity.
G.
An emergency access shall be approved by the Department of Public
Safety.
An agreement for financing ongoing maintenance shall be provided
by the property owners benefiting from the private road or shared
driveway. The Township's private road agreement shall be recorded
with the Wayne County Register of Deeds prior and provided to the
Building Department prior to the issuance of a building permit.
A.
Prior to issuing building permits for locations served by a private
road, the road and utilities shall be completed to the satisfaction
of the Department of Public Services and Department of Public Safety.
A.
Existing private roads and shared driveways lawful prior to the adoption
of this article but not in compliance with the standards herein are
considered to be legal nonconforming roads or easements. The intent
of this article is to permit legal nonconforming roads and easements
to continue and undergo routine maintenance for safety purposes, as
determined by the Township Engineer.
B.
This article is intended to discourage the extension of nonconforming
roads or increase in the number of lots or building sites served by
such a road. Any reconstruction, widening or extension of a nonconforming
private road or access easement shall be in conformity with this section.
C.
This article is also intended to allow a new dwelling unit to be
constructed on an existing lot of record having frontage along the
nonconforming private road or shared driveway prior to the adoption
date of this section, provided the road is reasonably capable of providing
sufficient access for the uses permitted in the zoning district and
emergency service vehicles.
D.
For purposes of determining whether a lot along a private road or
access easement qualifies as an existing lot, as used in this section,
at least one of the following conditions must have existed at the
time this article was adopted, October 10, 1991:
(1)
The lot consists of a condominium unit for which a master deed
had been recorded with the Wayne County Register of Deeds in accordance
with the requirements of the Michigan Condominium Act and other applicable
laws and ordinances.
(2)
The lot consists of a parcel that was described by metes and
bounds as recorded by a deed or as a land contract and registered
with the Wayne County Register of Deeds.
(3)
The lot has been assigned a unique parcel number by the Wayne
County Register of Deeds and was individually assessed and taxed on
that basis.
