[HISTORY: Adopted by the Town Board of the Town of New Glarus 11-19-1999.
Amendments noted where applicable.]
In order to clarify this chapter the following definitions are applicable:
That portion of road extending 100 feet on each side of a culvert
or bridge.
The supporting base material of the roadway, including shoulder.
The rate of ascent or descent of roadway.
The road or way over which the public generally has a right to pass,
to include the complete right-of-way.
The whole material laid in place and ready for travel.
The traveled portion of the highway.
The top of the roadway, or traveled surface.
This chapter shall be applicable to all highways laid out by the Town
Board after adoption of this chapter, including any highways dedicated in
plats for proposed subdivisions submitted for review pursuant to Ch. 236,
Wis. Stats., any private highways being donated to the Town, and any other
highways being accepted by the Town as public highways in the Town.
The following minimum design standards shall apply under this chapter.
All Town highways shall be classified as local roads unless designated by
the Town Board as collector or arterial. The classification of all roads under
this chapter shall be within the complete discretion of the Town Board considering
such factors as traffic count, character of anticipated traffic, and relation
of highway to traffic patterns within the Town and other highway systems.
It is intended that the local roads be the lowest traffic count, with access
to private property as the principal function. Collector highways are intended
to be highways acting as collectors from local roads to higher priority roads
or developed areas. Arterials are intended to serve as corridors through the
Town serving interregional and inter-area traffic movement.

Notes:

|
*
|
*Minimum grade is 0.5 on all classes of roadway.
|
B.
Culs-de-sac (permanent and temporary). Maximum desirable
length of cul-de-sac roads designed to have one end permanently closed is
1,000 feet with a turnaround of not less than 120 feet in diameter and a roadway
turnaround of 96 feet in diameter. Through roads are most desirable, and permanently
dead-ended streets shall be prohibited.
C.
Base course standards. The minimum standard will be a
roadway base of 10 inches of compacted in-place crushed aggregate base course
of Gradation No. 2 in the top layer and Gradation No. 1 and No. 2 in the lower
level. Base course must be of a quality, thickness, and composition suitable
for the location and class of roadway.
D.
Surface course standards.
(1)
The surface source for local roads shall have a minimum
of three-inch thick compacted hot-mix bituminous concrete composition, placed
in two layers, a binder course of 1 1/2 inches thick and a surface course
of 1 1/2 inches thick.
(2)
The surface course for collector and arterial roads will
be determined based on anticipated traffic loads but will at a minimum meet
the standards outlined for local roads.
E.
Ditching and culverts. The ditching of the roadway must
be complete and have proper elevation to provide for adequate drainage. Any
culverts necessary for proper drainage shall be installed after elevation
and location are obtained from the Town Board. The minimum length of culvert
installed in a roadbed shall be two feet greater than the base course width.
Apron end walls shall be used. The diameter and length will be subject to
the approval of the Town Board, after the amount of flowage is determined.
In no case shall the culvert be less than 18 inches in diameter.
F.
Bridges. All bridges shall meet the minimum requirements
of state and federal law. In the event that it is decided by the Town Board
that the construction of a bridge would be of a size and cost that would create
a hardship to the owner of the land required to build said bridge, then the
Town Board may proceed to accept the road, complete as required above, except
that part extending 100 feet on each side of said bridge. This portion of
the road shall be known as the "approach." The approach will be accepted uncompleted,
with the reservation that the Town will bill back to the owner a portion of
the cost of the construction of the bridge. The Town will proceed to build
said bridge and approach with the help of bridge aid, if available, and bill
the balance not covered by the aid or portion to be billed back to the owner.
The Town Board may grant variances from the minimum standards of § 75-3 in situations where strict application of the minimum standards is impractical or would impose undue hardship on the owner or developer of the road.
The road design standards in § 75-3 as stated above are intended to be minimum design standards. The Board shall have the discretion to impose higher design standards where, in the opinion of the Town Board, local conditions require higher standards or anticipated traffic in quantity or quality will require higher standards.
A.
Any person may apply to the Town Board to determine what
design standards should apply in a particular location, giving the description
of the proposed highway and the proposed design standards being requested
to be approved for any proposed highway being proposed to be built. No person
shall commence construction of any highway anticipated to be turned over to
the Town without having written approval of the proposed highway design by
the Town Board.
B.
The proposed highway design shall be accompanied by an
erosion control plan. Both the proposed highway design and the erosion control
plan must be prepared by a professional engineer licensed by the State of
Wisconsin. The Town Board shall base its written approval or denial of the
proposed highway design and erosion control plan upon the opinion of an engineering
firm designated by the Town Board. Such engineering costs shall be the expense
of the applicant(s)
All roadway surveys, engineering opinions, dedications, plans and specifications
and construction of any highway to be dedicated to the Town will be at the
expense of the applicant or applicants. This includes any expense incurred
by the Town in the preparation of plans and review and inspection of plans
and construction.
Upon completion of the proposed highway, the Town Board will proceed
to have its designated engineering firm make final inspection. Acceptance
or rejection of the highway shall be based on the opinion of the designated
engineering firm and shall be in the discretion of the Town Board. If the
highway is rejected, then corrections must be made as stated by the Town Board
before final inspection will be made again. If final acceptance is made by
the Town Board, the owner or owners will turn over to the Town a warranty
deed free and clear of any liens to covey free and clear title to the Town
for the highway.
