Village of Greenville, WI Lot and Street Layout Design Standards

Compliance with statutes. In laying out a CSM or plat, the land divider/subdivider shall conform to the provisions of Ch. 236, Wis. Stats., and all applicable Greenville regulations. In all cases where the requirements of this chapter are different from the requirements of Chapter 236, the more restrictive provision shall apply.

Dedication. The land divider/subdivider shall dedicate land and improve streets as provided in this chapter. Streets shall be located with due regard for topographical conditions, natural features, existing and proposed streets, utilities, land use, and public convenience and safety.

Compliance with Comprehensive Plan and Official Map. The arrangement, character, extent, width, grade and location of all streets shall conform to any Greenville Comprehensive Plan, the Comprehensive Outdoor Recreation Plan (CORP) and Official Map and to this chapter and shall be considered in their relation to existing and planned streets, to reasonable circulation of traffic, to topographical conditions, to runoff of stormwater, to public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets. The arrangement of streets in new subdivisions and certified survey maps shall make provision for the appropriate continuation at the same width of the existing streets in adjoining areas.

Areas not covered by Official Map or Comprehensive Plan. In areas not covered by the Greenville Comprehensive Plan, the Comprehensive Outdoor Recreation Plan (CORP) or Official Map, the layout of streets shall conform to the plan for the most advantageous development of adjoining areas of the neighborhood. Streets shall be designed and located in relation to existing and officially planned streets, topography and natural terrain, streams and existing tree growth, public convenience and safety and in their appropriate relation to the proposed use of the land to be served by such streets.

Street classifications. Streets shall be classified as indicated below and further defined in Article III:

(1)

Arterial streets. Arterial streets shall provide through traffic for a heavy volume of vehicles.

(2)

Collector streets. Collector streets shall provide ready collection of traffic from commercial and residential areas and conveyance of this traffic to the arterial street and major thoroughfare system. Collector streets shall relate property to special traffic generators such as schools, churches and shopping centers and other concentrations of population and to the major streets into which they feed. Direct driveway access from single-family and two-family residential lots shall be prohibited unless the Greenville Engineer finds it is not practical due to physical or environmental constraints or an urban-style grid system is being proposed; collector streets should be designated as limited-access roadways and noted as such on the plat. [Cross reference: § 270-52C.]

(3)

Local streets. Local streets shall conform to the topography, discourage use by through traffic, permit the design of efficient storm and sanitary sewage systems and require the minimum street area necessary to provide safe and convenient access to abutting property and shall convey traffic to collector streets; conveyance of traffic to arterial streets shall be prohibited unless the Greenville Engineer finds it is not practical due to physical or environmental constraints or an urban-style grid system is being proposed.

(4)

Proposed streets. Proposed streets shall extend to the boundary lines of the tract being subdivided unless prevented by topography or other physical conditions or unless, in the opinion of the Board, such extension is unnecessary or undesirable for the coordination of the layout of the subdivision or land division or for the advantageous development of the adjacent tracts.

Reserve strips. Reserve strips are prohibited on any plat to control access to streets, except where control of such strips is placed with Greenville or county under conditions approved by the Board or county.

Continuation. Streets shall be laid out to provide for possible continuation wherever topographic and other physical conditions permit. All proposed streets shall have a direct connection with, or be continuous and in line with, existing, planned or platted streets with which they are to connect. Proposed streets shall extend to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions, or unless, in the opinion of the Board, such extension is unnecessary for the coordination of the layout of the subdivision with existing layout or the most advantageous future development of adjacent tracts.

Number of intersections. The number of intersections of local streets with collector/arterial streets shall be the practical minimum consistent with circulation needs and safety requirements, preferably not more than two.

Frontage roads. Where a subdivision abuts or contains an existing or proposed major thoroughfare, the Board may require a frontage road, nonaccess reservation along the rear of the property contiguous to such thoroughfare or such other treatment as may be necessary to ensure safe, efficient traffic flow and adequate protection of residential properties.

Private roads. Private roads are prohibited, except as part of a condominium development, and the Board shall not permit installation of public improvements in any private road.

Visibility. Streets shall afford maximum visibility and safety and shall intersect at right angles where practicable. As required by the Engineer, sufficient vision clearance triangles shall be provided at intersections. Stopping sight distances shall be provided to comply with Chapter 3, "A Policy of Geometric Design of Highways and Streets," latest edition, published by the American Association of State Highway and Transportation Officials (AASHTO) and as per Chapter 320, Zoning.

Tangents. A tangent at least 100 feet long shall be required between reverse curves on arterial and collector streets. On all roads, a tangent at least 100 feet long shall be provided between the curve and any intersection.

Access. The subdivision or certified survey map shall be designed to provide each lot with direct access to a public street or road with the lot directly adjacent to/has frontage on the public street or road or through an access easement. Lots with access easements shall be considered unbuildable, and no building permits shall be issued to build until the lot has been granted direct access from the adjacent public road; a note shall be placed on the plat/CSM for lots that do not have frontage along a public street, are unbuildable and building permits shall not be issued until access is granted. Access shall also comply with the access requirements of Chapter 320.

Radii of curvature. When a continuous street center line deflects at any one point by more than 1° in rural areas or by more than 3° in urban areas, a circular curve shall be introduced, having a radius of curvature on said center line of not less than the following:

(1)

Arterial streets and major thoroughfares: 500 feet.

(2)

Collector streets: 300 feet.

(3)

Local streets: 150 feet.

Half streets and streets that abut adjacent property. Where an existing dedicated or platted half street is adjacent to the subdivision or CSM, the land divider/subdivider shall dedicate the other half-street. The platting of half streets should be avoided where possible. When a full street is platted that abuts an adjacent property, the land divider/subdivider must submit a written agreement with the adjacent property owner, to be approved by the Board and recorded with the County Register of Deeds, documenting how future development costs will be assessed.

Intersections.

(1)

Property lines at street intersections of major thoroughfares shall be rounded with a radius of 15 feet or greater where the Engineer considers it necessary.

(2)

Streets shall intersect each other at as nearly right angles as topography and other limiting factors of good design permit.

(3)

Number of streets converging at one intersection shall be reduced to a minimum, preferably not more than two.

Street names. New street names shall not duplicate the names of existing streets, but streets that are continuations of others already in existence and named shall bear the names of the existing streets. Street names shall be subject to approval by the Planning Commission and Board. The U.S. Postal Service shall be contacted to assure no duplicative or similar-sounding street names exist within the postal district. Outagamie County shall review for 911 purposes.

Cul-de-sac.

(1)

Cul-de-sac dimensions. Cul-de-sac streets designed to have one end permanently closed shall not exceed 600 feet in length. All cul-de-sac streets designed to have one end permanently closed shall terminate in a circular turnaround having a minimum right-of-way radius of 60 feet and a minimum inside curb radius of 48 feet. The Planning Commission or Board may require larger sizes for longer cul-de-sacs where school bus turnarounds are expected.

(2)

Temporary dead ends or cul-de-sacs. All temporary dead ends shall have a maximum length of 600 feet, and a temporary cul-de-sac shall have a minimum right-of-way radius of 60 feet and a minimum inside curb radius of 48 feet, except where larger sizes may be needed due to expected school bus turnarounds.

(3)

Dead ends. Dead-end streets not over 500 feet in length are permitted when necessitated by the topography that are not able to connect in the future for continuation of the street.

(4)

Limited use of cul-de-sacs. Cul-de-sacs shall be limited in use for emergency and life safety reasons. Cul-de-sacs should only be permitted when there are limited options to put a road through. Examples when a cul-de-sac could be considered is when a road could not be physically put through due to physical constraints of the land proposed for development. A cul-de-sac should not be considered when it is simply a desired design feature. Written justification shall be provided as to why a cul-de-sac is required and be approved by the Board.

Major thoroughfare and railroad right-of-way treatment. Whenever the proposed CSM or subdivision contains or is adjacent to a major thoroughfare or railroad right-of-way, the design shall provide the following treatment:

(1)

Subdivision lots. When lots within the proposed CSM/subdivision back upon the right-of-way of an existing or proposed arterial or collector street or a railroad, a planting strip of at least 30 feet in depth shall be provided adjacent to the street or railroad in addition to the normal lot depth. This strip may be part of the platted lots or a separate lot owned and maintained by an established homeowners' association, but shall have the following restriction lettered on the face of the plat: "This strip reserved for the planting of trees and shrubs; the building of structures hereon prohibited."

(2)

Commercial and industrial districts. Commercial and industrial districts shall provide, on each side of an existing or proposed arterial or collector street or railroad, streets approximately parallel to and at a suitable distance from such arterial or collector street or railroad for the appropriate use of the land between such streets, existing or proposed arterial or collector streets or railroad, but not less than 150 feet.

(3)

Streets parallel to an arterial or collector street. Streets parallel to an existing or proposed arterial or collector street or railroad right-of-way, when intersecting an arterial street or collector street which crosses said arterial, collector or railroad, shall be a minimum distance of 250 feet from said existing or proposed arterial or collector street or railroad right-of-way. Such distance, where desirable and practicable, shall be determined with due consideration of the minimum distance required for the future separation of grades by means of appropriate approach gradients.

(4)

Local streets. Local streets immediately adjacent and parallel to railroad rights-of-way shall be avoided, and location of local streets immediately adjacent to arterial streets and highways and to railroad rights-of-way shall be avoided in residential areas.

Public road right-of-way width. All streets and highways constructed in Greenville or to be dedicated to Greenville shall fully comply with the following construction standards:

(1)

Local roads: minimum 66 feet.

(2)

Collector roads: minimum 80 feet.

(3)

Arterial roads: minimum of 120 feet.

(4)

All other streets and roads: minimum of 66 feet.

(5)

Cul-de-sac and bulb radius: minimum of sixty-foot radius.

Block design. The lengths, widths and shapes of blocks shall be appropriate for the topography and the type of development contemplated, but block length in residential areas shall not exceed 1,200 feet nor have insufficient width to provide for two tiers of lots of appropriate depth between street lines except when lots back up to a collector or arterial street. As a general rule, blocks shall be no less than 750 feet in length. A block may have a single tier of lots where it adjoins a railroad, arterial or collector street or stream or park.

Pedestrian pathways/trails. In addition to the minimum required facilities identified in § 270-52, pathways/trails may be required by the Board wherever deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities. Pathways/trails shall also be required and be consistent with the Greenville Bicycle and Pedestrian Plan. Pathways shall be placed within public right-of-way, outlots or easements.

Lot design.

(1)

Size, shape and orientation of lots shall be appropriate for the location of topography of the subdivision, the type of sewage or septic system to be utilized, and for the type of development contemplated. Each lot shall be designed to provide an aesthetically pleasing building site and a proper architectural setting for the buildings contemplated.

(2)

Width and size of lots shall conform to the requirements of Chapter 320, Zoning.

(3)

Depth and width of properties reserved or laid out for commercial or industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated and as required by Chapter 320, Zoning.

(4)

Residential lots shall not front or have access to arterial or collector streets unless the Greenville Engineer finds it is not practical due to physical or environmental constraints or an urban-style grid system is being proposed. If they are allowed access the lots may be required to be platted with extra depth or design to alleviate the effect of major street traffic on residential occupancy.

(5)

In the subdividing of any land, regard shall be shown for all natural features, such as tree growth, watercourses, historic spots or similar conditions which, if preserved, will add attractiveness and stability to the proposed development.

(6)

All remnants of lots below minimum size left over after subdividing of a larger tract must be added to adjacent lots, or a plan shown as to future use rather than allowed to remain as unusable parcels.
