Editor's Note: The Grant County Highway Plan is included at the end of this chapter.
B. 
Classification of highways. The public roads, streets and highways of Grant County are hereby divided into the following five functional classifications of highways as set forth in the State Highway Plan. The highways so classified are shown on the Grant County Highway Plan which is included as a component part of the Grant County Subdivision Regulations and therefore made a part of the original copy of this chapter as fully as if set forth at length herein.
Functional Classification
Highway Classification
Class A Highways
Principal arterial highways for which right-of-way lines have been officially mapped. Primary arterial highways.
Class B Highways
Standard arterial highways. Principal arterial highways without or prior to having officially mapped right-of-way lines.
Class C Highways
Minor arterial and high collector highways. All state trunk highways not designated as a Class A or Class B Highway.
Class D Highways
Low collector highways and all county trunk highways not otherwise designated as a Class A, Class B or Class C Highway.
Class E Highways
Local highways, town roads and public roads and streets other than those listed above.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
The arrangement, character, extent, width, grade and location of all streets shall conform to all official maps and may be required to conform to master plans and shall be developed and located in proper relation to existing and planned streets; topographic conditions; existing natural features, including streams, lakes and tree growth; public convenience and safety; existing and proposed uses of land served by such streets; and to the most advantageous development of adjoining uses. Specifically all streets shall be designed in accordance with the following criteria:

NOTES:
*These standards apply to cul-de-sac and loop streets that are projected to serve fewer than 15 dwelling units.
If Wisconsin Statutes require a larger right-of-way width for the road or a lesser maximum grade, the road shall meet said more restrictive statutory requirement.
A. 
Alignment.
(1) 
The arrangement of streets in a subdivision shall provide, where possible, for the continuation or appropriate projection of existing or proposed local, collector and arterial streets in the area. Local streets shall be laid out so as to discourage their use by through traffic.
(2) 
Roads and streets in a subdivision shall extend to the boundaries of the tract or land being subdivided, except where prevented by topography or other physical condition or determined to be unnecessary or undesirable for the particular layout of the subdivision or the orderly development of adjacent tracts of land.
(3) 
The number of intersections along arterial streets shall beheld to a minimum. Wherever practicable the distance between such intersections shall be not less than 1,200 feet.
(4) 
Street jogs with center-line offsets of less than 150 feet shall be avoided.
(5) 
A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
(6) 
Streets shall be laid out so as to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 75°, and not more than two streets shall intersect at one point. Exceptions may be granted due to steep or unusual terrain as approved by the County Engineer.
(7) 
Half streets shall be prohibited except where necessary for continuity of the street plan in the area.
B. 
Access.
(1) 
Local roads or streets in a subdivision shall be designed to provide suitable access to abutting properties and to discourage their use by through traffic. Collector roads or streets shall be provided where anticipated traffic volumes exceed the practical capacity of such local roads or streets.
(2) 
Where a subdivision abuts or contains an existing or planned arterial road, street, or highway, adequate protection of adjacent properties, access control, and the separation of through and local traffic shall be provided by reversed frontage with screen planting in a non-access reservation along the rear property lines or by the use of frontage roads or streets. Said arterial roads, streets, or highways shall include all Class A, Class B, and Class C highways and such other roads, streets, or highways so designated by the highway agency having jurisdiction thereover.
(3) 
Where a subdivision borders on or contains a railroad or limited access highway right-of-way, roads or streets shall be provided approximately parallel to such right-of-way as necessary for the appropriate use of the intervening land with due regard for the requirements of approach grades and future grade separation.
(4) 
Public alleys may be required to provide off-street loading and service access to commercial, industrial or institutional establishments but shall not be approved in residential areas except where unusual or extraordinary conditions prevail. No such alleys shall connect to an arterial road or street or terminate without a suitable turnaround facility.
(5) 
Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the Planning and Zoning Committee, under conditions approved by said Planning and Zoning Committee.
C. 
Cul-de-sac and dead-end streets.
(1) 
Culs-de-sac shall not exceed 1,000 feet in length and shall provide a turnaround with a minimum right-of-way radius of 55 feet and roadway.
(2) 
Dead-end streets shall not be permitted without a suitable turnaround. Appropriate arrangements shall be made for those parts of temporary turnarounds outside of the street right-of-way to revert to the abutting property owners at such time as streets shall be extended.
D. 
Street names. The name of any subdivision road or street shall be reviewed and approved or disapproved in accordance with the following criteria:
(1) 
No road or street name shall duplicate, or be so similar to, road or street names in the area as to cause confusion.
(2) 
Where a road or street maintains the same general direction or orientation, the existing name and suffix or the same name and suffix shall continue for the entire length of the road or street.
(3) 
The suffix "Boulevard" shall be limited to roads and streets with divided pavement or the projection or extension of the same.
(4) 
The suffix "Circle" or "Court" shall be limited to roads and streets terminating with a cul-de-sac.
(5) 
The suffix "Lane" or "Drive" shall be limited to minor roads and streets not more than one block in length.
(6) 
The suffix "Parkway" shall be limited to roads and streets abutting or traversing a park or greenway or watercourse.

Where the lots abut navigable waters, building setback line for all buildings and structures, except piers, marinas, boathouses and similar uses, shall be shown on the plat and shall not be less than 75 feet from the normal high-water line.
B. 
Vision corners.
(1) 
The setback lines for a corner lot shall be modified to provide a vision corner consisting of a triangular area within which no obstruction to view from an oncoming vehicle is permitted.
(2) 
All such vision corners shall be bounded by the right-of-way lines of the highways, roads, or streets and a vision clearance setback line connecting points on each right-of-way line which are located a distance back from the intersection equal to the following setbacks required on the street, road or highway:[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
All plats and subdivisions must meet the following requirements:
A. 
The length, width, and shape of blocks shall be suited to the planned use of the land, zoning requirements, needs for convenient access, control and safety of street traffic, and the limitations and opportunities of topography. Block lengths in residential areas shall not, as a general rule, be less than 600 feet in length between street lines unless dictated by exceptional topography or other limiting factors of good design.
B. 
Blocks shall have sufficient widths to provide two tiers of lots of appropriate depth, except where otherwise required to separate residential development from through traffic.
C. 
Pedestrianways or crosswalks, not less than 10 feet in width, shall be provided near the center and entirely across any block 900 feet or more in length where essential to provide adequate pedestrian circulation or access to schools, shopping centers, churches, or transportation facilities.

F. 
Lot lines shall follow municipal boundary lines rather than cross them.
G. 
Double frontage or reverse frontage lots shall be avoided except where essential to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation. A planting screen easement of at least 10 feet shall be provided along the line of lots abutting such a traffic artery or other disadvantageous use.
H. 
No lot shall front on the right-of-way of any Class A Highway, on the right-of-way of any ramp or turning or acceleration or deceleration lane of any interchange on a Class A Highway, or on any public road, street or highway intersecting or interchanging with a Class A Highway within 1,000 feet of such intersection or interchange.

All plats and subdivisions must meet the following requirements:
A. 
Utility easements shall be provided where necessary to service the subdivision in accordance with the recommendations of the respective utility companies, such easements to be along rear or side lot lines, with not less than seven feet of such easement on each side of the particular lot line, except where unusual or extraordinary conditions prevail.
B. 
Drainageway easements shall be provided where a subdivision is traversed by a watercourse, drainageway, channel or stream, except where a special exception is permitted. Said easements shall be of such alignment and width to accommodate the anticipated discharge from the upstream drainage basin with due allowance for the future development of upstream land.
C. 
Pedestrianways, including sidewalks and crosswalks, shall be provided for essential pedestrian circulation, such as access to schools, shopping centers, churches, and community and transportation facilities, and across the entire width of any block 800 feet or more in length, such pedestrianways to be located within a public right-of-way or within an easement of not less than 10 feet in width.
D. 
Multipurpose easements for drainageways, pedestrianways and/or utilities may be provided where the same would satisfy the requirements heretofore set forth and further the orderly development of the land being subdivided.
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
All plats and subdivisions must meet the following requirements:
A. 
Public approval. Any part of a street, drainageway or other public way which is indicated on a comprehensive plan or plan component or a plat shall conform to the arrangement, width and location indicated and shall be offered for dedication to the County or town. The required right-of-way for new public roads, streets, or highways shall be dedicated to the public. Such dedications must be approved by the governing body having jurisdiction thereover, and said body reserves the right to refuse any or all such dedications. All public ways, easements, reservations, reserve strips, and any approved names thereof shall be shown on the final plat.
B. 
Subdivisions abutting on a navigable lake or stream shall, according to the provisions of § 236.16(3), Wis. Stats., provide access at least 60 feet wide to the low-water mark so that there will be public access which is connected to existing public roads at not more than one-half-mile intervals as measured along the lake or stream shore, except where greater intervals and wider access are agreed upon by the Wisconsin Department of Natural Resources and the Department of Administration, and excluding shore areas where public parks or open space streets or roads on either side of a stream are provided.
(1) 
The Planning and Zoning Committee may require dedications of access points of greater width or at more frequent intervals at points designated by it.
(2) 
The lands lying between the meander line, established in accordance with § 236.20(2)(g), Wis. Stats., and the water's edge, and any otherwise unplattable lands which lie between a proposed subdivision and the water's edge, shall be included as part of lots, outlots or public dedications in any plat abutting a lake or stream. This requirement applies not only to lands proposed to be subdivided but also to all lands under option to the subdivider or in which he holds any interest and which are contiguous to the lands proposed to be subdivided and which abut a lake or stream as provided in § 236.16(4), Wis. Stats.
(3) 
Reservations, or reserve strips for the control of access to streets, shall be placed under the control of the governing body having jurisdiction over such streets. Reservation of land for public acquisition shall be for a period not to exceed three years. Land so dedicated or reserved must be shown on the final plat.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
A. 
The requirements and standards of this chapter may be modified by the Planning and Zoning Committee for planned developments, provided that such proposed developments shall be planned as a unit, shall be appropriate to the site and location, shall be a minimum of 10 acres, and shall not conflict with other laws or requirements or with the purpose or intent of this chapter and are approved by the Planning and Zoning Committee. In addition, continued provision, maintenance, and use of open space, recreation areas, services, and amenities shall be assured in a manner acceptable to the Planning and Zoning Committee. Also, for single-family development a maximum density of five units per gross usable acre shall be required.
B. 
It is the intent of this section to permit, in addition to other types of planned development, cluster subdivisions and planned unit developments with owner-occupied row housing and with privately owned common property comprising a major element of the development.
