(A) Street plan.
(1) The arrangements, classification, extent, width, grade and location of all streets shall conform to the street plan of the town and shall be designed in relation to existing and planned streets, topographical conditions, public convenience and safety and the proposed uses of the land to be served by such streets and the town’s drainage study.
(2) All classifications streets shall be paved, shall be curbed and guttered and shall be constructed to town specifications.
(B) Street classification.
(C) Public use streets. In all new developments and subdivisions, streets that are dedicated to public use shall be classified as provided below, as provided in the roadway design criteria of the town:
(1) The classification shall be based upon the projected volume of traffic to be carried by the street, stated in terms of the number of trips per day;
(2) The number of dwelling units to be served by the street may be used as a useful indicator of the number of trips but is not conclusive; and
(3) Whenever a subdivision street continues an existing street that formerly terminated outside the subdivision or is expected to be continued beyond the subdivision at some future time, the classification of the street will be based upon the street in its entirety, both within and outside of the subdivision.
(D) Classification of streets. The classification of streets shall be as follows:
(1) Local. A street which provides direct access to adjacent property, including residential uses. Local streets typically are designed to discourage through traffic from neighborhoods;
(2) Collector. A street which permits relatively unimpeded traffic movement, collects traffic from the local system and where traffic demands are relatively high, but where a higher classification street is not warranted. No back-out drives are permitted;
(3) Arterial. A street with signals at important intersections and stop signs on the side streets, and which collects and distributes traffic to and from collector streets. Arterials can act as boundaries between neighborhood areas or different land uses; and
(4) Freeway. Completely controlled access highways designed to provide interstate or intercity traffic flow, with grade separations at intersections. No private access.
(E) Access to lots. Every lot shall have access to a public road or street that is sufficient to afford a reasonable means of ingress and egress for emergency vehicles as well as for all those likely to need or desire access to the property in its intended use.
(F) Access to arterial streets. Whenever a development that involves the creation of one or more new streets borders on or contains an existing or proposed arterial street, no direct driveway access may be provided from the lots within this development onto this street.
(G) Entrances to streets. All driveway entrances and other openings onto streets within the town’s planning jurisdiction shall be constructed so that:
(1) Vehicles can enter and exit from the lot in question without posing any substantial danger to themselves, pedestrians or vehicles traveling in abutting streets;
(2) Interference with the free and convenient flow of traffic in abutting or surrounding streets is minimized; and
(3) If driveway entrances and other openings onto streets are constructed in accordance with the specifications and requirements of the town, if these exist, or the relevant special district, this shall be deemed prima facie evidence of compliance with the standard set forth in this chapter.
(H) Coordination with surrounding streets.
(1) The street system of a development or subdivision shall be coordinated with existing, proposed and anticipated streets outside it or outside the portion of a single tract that is being divided into lots (hereinafter, “surrounding streets”) as provided in this section.
(2) Collector and arterial streets shall intersect with surrounding collector or arterial streets at safe and convenient locations.
(3) Local and minor residential streets shall connect with surrounding streets where necessary to permit the convenient movement of traffic between residential neighborhoods or to facilitate access to neighborhoods by emergency service vehicles or for other sufficient reasons, but connections shall not be permitted where the effect would be to encourage the use of such streets by substantial through traffic.
(4) (a) Whenever connections to anticipated or proposed surrounding streets are required by this section, the street right-of-way shall be extended and the street developed to the property line of the subdivided property (or to the edge of the remaining undeveloped portion of a single tract) at the point where the connection to the anticipated or proposed street is expected.
(b) In addition, the town may require temporary turnarounds to be constructed at the end of such streets pending their extension when such turnarounds appear necessary to facilitate the flow of traffic or accommodate emergency vehicles. Notwithstanding the other provisions of this division (H), no temporary dead-end street in excess of 1,000 feet may be created unless no other practicable alternative is available.
(I) Relationship of streets to topography.
(1) Streets shall be related appropriately to the topography. In particular, streets shall be designed to facilitate the drainage and storm water runoff objectives set forth in this chapter, and street grades shall conform as closely as practicable to the original topography.
(2) Permissible roadway and intersection grades shall be as specified in the town roadway design criteria or other documents as approved by the town.
(J) Wheelchair ramps. Whenever curb and gutter construction is used on public or private streets, wheelchair ramps for the handicapped shall be provided at intersections and other major points of pedestrian flow. Wheelchair ramps and depressed curbs shall be constructed in accordance with standards of the town or appropriate special districts.
(K) Street names.
(1) Street names shall be assigned by the developer subject to the approval of the town. Proposed streets that are obviously in alignment with existing streets shall be given the same name. Newly created streets shall be given names that neither duplicate nor are phonetically similar to existing streets within the town’s planning jurisdiction, regardless of the use of different suffixes.
(2) Street names shall include a suffix such as the following:
(a) Cul-de-sacs: Way, Court or Lane;
(b) Short streets: Way, Place or Lane;
(c) Streets: Street, Parkway, Avenue or Drive; and
(d) Circular streets (both loops and at same street): Circle.
(3) Building numbers shall be assigned and/or approved by the town.
(L) Sidewalks.
(1) On streets other than local or minor collectors, landscaped parking strips of the following minimum widths must separate sidewalks from street flow line (and edge):
Street Type | Parking Strip Width (Minimum) |
Collector | 6 feet |
Arterial | 12 feet |
(2) The sidewalks required by this section shall be at least four feet in width and constructed according to the specifications of the town if these exist, or of the relevant special district, except that the town may permit the installation of walkways constructed with other suitable materials when it concludes that:
(a) Such walkways would serve the residents of the development as adequately as concrete sidewalks; and
(b) Such walkways would be more environmentally desirable or more in keeping with the overall design of the development.
(3) Whenever the town finds that a means of pedestrian access is necessary from the subdivision to schools, parks, playgrounds or other roads or facilities and that such access is not conveniently provided by sidewalks adjacent to the streets, the developer may be required to reserve an unobstructed easement of at least ten feet in width to provide such access.
(M) Bicycle lanes.
(1) Where trails or bike ways are shown on the town open space and parks plan as crossing a parcel proposed for development, the developer shall work with the town to establish an alignment through the parcel and dedicate this alignment to the town. In general, the width for trail or bike way dedication shall be 30 feet if not associated with a street. Areas dedicated for trails or bikeways may be included in the open space requirements of the development.
(2) Where on-street bicycle lanes are shown on the town circulation and transportation plan, an additional eight feet of street width and right-of-way shall be added to the street to accommodate the bicycle lane.
(3) Off-street bikeways should have right-of-way reserved and dedicated per this section.
(N) Blocks and lots.
(1) Blocks shall not exceed 1,320 feet in length nor be less than 360 feet in length, unless no practicable alternative is available. The length of blocks shall be considered to be the distance from street centerline to opposite street centerline and shall be measured through adjacent back lot lines or through the center of the block. The total design should provide for convenient access and circulation for emergency vehicles. All blocks shall be abutted by a street or streets. Pedestrian walkways shall be provided to permit acceptable pedestrian access to abutting streets.
(2) Service access to the interior of blocks may be permitted in certain instances, in which case such alleys must be indicated in the plan and plat.
(3) Lot standards.
(a) Division of lots. No lot shall be divided by a municipal or county boundary line, road, alley or other lot.
(b) Wedge-shaped lots. In the case of wedge-shaped lots, no lot shall be less than 20 feet in width where the narrow side of the lot is at the front property line.
(c) Lot lines. Side lot lines shall be substantially at right angles or radial to street lines. Where lot lines are not at right angles to the street lines, this shall be indicated.
(d) Corner lots. Corner lots in all subdivisions are required to have the minimum front yard requirements, as required by the zone district, facing both streets.
