In order to clarify this article 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 gradual drying of the highway by a system of ditches,
trenches, channels, etc.
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.[1]
[1]
Editor's Note: The definition of "surface
1/2" which immediately followed this definition was deleted 12-10-2007
by Ord. No. 1-2007.
This article shall be applicable to all highways
laid out by the Town Board after adoption of this article, including
any highways dedicated in plats for proposed subdivisions submitted
for review pursuant to Ch. 236, Wis. Stats., and private highways
being donated to the Town, and any other highways being accepted by
the Town as public highways in the Town.
A.
The following minimum design standards shall apply
under this article. 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 article 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 local 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 intra-regional and
inter-area traffic movement.

B.
Base course. Base course must be of a quality, thickness,
and composition suitable for the location.
C.
Surface course. Surface course must consist of either
crushed aggregate or bituminous concrete composition suitable for
anticipated traffic loads. The minimum amount of gravel necessary
for acceptance must be at least 600 yards per mile. The minimum amount
of pavement necessary for acceptance must be at least 2 1/2 inches
in thickness. (Note: These minimums may vary around the state and
should be reviewed and established by each Town Board considering
local conditions.)
D.
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 any culvert installed in a roadbed shall be at least
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 the flowage in determined. In
no case shall the culvert be less than 18 inches in diameter.
E.
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 it would create a hardship to the owner of 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 uncomplete, with the reservation that
the Town will bill back to the owner a portion of the cost of construction
of such 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 road design standards in § 298-3 as stated above are intended to be minimum design standards. The Town 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.
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 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 signed by the Town Board.
Upon completion of the proposed highway, the
Town Board will proceed to make final inspection, accepting or rejecting
the highway as the case may 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 finals 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
necessary to convey free and clear title to the Town for the highway.
