Article 5A: Street Regulations

Summary

Streets are an integral component of community design and represent the largest percentage of public open space in town. In Huntersville, public streets are designed with the land uses adjacent to the street to safely accommodate mobility, access and travel for all users. All streets should connect to help create a comprehensive network of public areas to allow movement of automobiles, transit vehicles, bicyclists and pedestrians. All elements of community design must be incorporated with the design of the street network to promote motorized speeds that are appropriate to their context. 

The process described in this Article in conjunction with the Town's Engineering Standards and Procedures Manual shall be used for the design of all public streets in the Town's jurisdiction, which includes both the Town corporate limits and the Extraterritorial Zoning Jurisdiction (ETJ). 

In summary, streets shall:

1. Incorporate appropriate accommodations for all modes of transportation including, vehicles, pedestrians, bicycles and transit users, and may include users amenities such as shelters, benches and bike racks.

2. Interconnect within a development and with adjoining development. Cul-de-sac shall be allowed only where topographical and/or adjacent development offer no practical alternatives for connections or through traffic. Street stubs shall be provided within development adjacent to vacant land or land suitable for redevelopment, wherever possible, to provide for future connections. The Land Development Map, Huntersville Community Plan and any applicable Small Area Plans should be reviewed to locate potential connections in new neighborhoods.

3. Be bordered by sidewalks on both sides, with the exception of ditch-type local streets, alleys, and the undeveloped edge of parkways (see Article 7.11). Sidewalks on one side of the road may be permitted in the Rural zone as an incentive to protect water quality.

4. Be lined with street trees on both sides, with the exception of ditch-type local streets, alleys, and the undeveloped edge of parkways (see Article 7.11).

5. Be public. Private streets are not permitted within any new development. Alleys will be classified as public or private depending on function. Private drives are permitted only as described in the Rural and Transitional zone. 

6. Generally, all buildings will front on public streets.

Intersections & Blocks

Intersections and Blocks

Intersections

Segments of straight streets should be interrupted by intersections designed to

a. disperse traffic flow and reduce speeds, thereby eliminating the creation of de facto collector streets with high speed, high volume traffic; and

b terminate vistas with a significant natural feature, a building, a small park, or other public space.

Other traffic calming measures such as neckdowns, chicanes, mid-block diverters, intersection diverters, curb bulbs, serial hill crests, and related devices will be considered on a case by case basis, based on safety and appropriateness in the proposed location.

Blocks

Street blocks defined by public streets are the fundamental design elements of traditional neighborhoods. In urban conditions, any dimension of a block may range from 250 to 500 linear feet between cross streets. In major subdivisions the dimension of blocks may not exceed 800 linear feet between cross streets. Within large-lot subdivisions the blocks may be up to 1500 feet. The block pattern should continue to establish the development pattern at the project edge. Where a longer block will reduce the number of railroad grade crossings, major stream crossings, or where longer blocks will result in an arrangement of street connections, lots and public space more consistent with this Article and Article 7 of these regulations, the Town Board may authorize greater block lengths at the time of subdivision sketch plan review and approval.

Acceptance of Streets

Streets shall be accepted in accordance with the Street Acceptance Policy adopted by the Board of Commissioners and on file in the office of the Town Manager.

Street Plan Types

The layout of streets should provide structure to the neighborhoods. The formality of the street plan will vary depending upon site conditions and topography. Unique site conditions should be used to create special neighborhood qualities. The following are examples of street plan types, noting advantages and disadvantages.

Organic Network
Curviliniar Network
Orthogonal Grid
Diagonal Network

Defining the Public Space of the Street

As the most prevalent public spaces in Huntersville, streets should be spatially defined by buildings. Proper alignment and delineation of the public street space occurs when the facades of adjacent buildings are aligned much like the walls forming a room. Buildings that make up the street edges are aligned in a disciplined manner. The defined space observes a certain ratio of height to width.

Building articulation must take place primarily in the vertical plane of the façade. Appendages such as porches, balconies, and bay windows are encouraged to promote the transition between the public street and the private dwelling.

For good definition, the ratio of one increment of height to six of width is the absolute maximum, with one to three being a good effective minimum. As a general rule, the tighter the ratio, the stronger the sense of place. Very tight relationships of one to one can create special pedestrian places.

In the absence of spatial definition by facades, disciplined tree planting is an alternative. Trees aligned for spatial enclosure are necessary on streets with deep building setbacks.
