[Amended 2-23-1982; 9-16-2014 by L.L. No. 3-2014]
Streets shall be suitably located, having widths as specified in § 103-69 and adequately constructed to accommodate the prospective traffic and to afford satisfactory access to police, firefighting, snow-removal and other road maintenance equipment. The arrangement of streets shall be such as not to cause undue hardship to adjoining properties and shall be coordinated so as to compose a convenient system.
The arrangement, width, grade and location of all streets shall conform to the Master Plan and any plan for the neighborhood approved by the Planning Board and shall be considered in relation to existing and planned streets, to topographic conditions, to public convenience and safety and in their appropriate relation to the proposed uses of the land to be served by such street.
[Amended 2-28-1989 by L.L. No. 2-1989]
Local, minor and rural streets shall be planned so that their use by through traffic will be discouraged.
A. 
Streets shall be logically related to the topography of the property, and all streets shall be arranged so as to obtain as many as possible of the building sites at or above the grades of streets.
B. 
The grades of streets shall conform as closely as possible to the original topography. A combination of steep grades and sharp curves shall be avoided.
A. 
Where a subdivision abuts or contains an existing or proposed major street, the Planning Board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the property line or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
B. 
Where the subdivision abuts or fronts onto a major street, sidewalks shall be required of a size and type to be approved by the Planning Board.
C. 
Where a subdivision borders on or contains a railroad right-of-way or limited-acess highway right-of-way, the Planning Board may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land, such as for park purposes in residential districts. Such distances shall be determined with due regard for the requirements of approach grades and future grade separations.
Where a tract is subdivided into lots substantially larger than the minimum size required in the zoning district in which a subdivision is located, the Planning Board may require that streets and lots be laid out so as to permit future resubdivision in accordance with the requirements contained in these regulations.
Where the subdivision borders on an existing street and the Master Plan, the County Superintendent of Highways or the Town Superintendent of Highways indicates plans for realignment or widening of the street that would require reservation of some land of the subdivision, the Planning Board shall require that such areas be shown and marked on the subdivision plat as "reserved for street realignment (or widening) purposes."
The minimum building setback shall be 30 feet from the front property line.
A. 
Intersections of major streets by other streets shall be held to a minimum and shall be at least 800 feet apart, if possible.
B. 
Cross-street intersections shall be avoided, except at important traffic intersections.
C. 
A distance of at least 250 feet shall be maintained between offset intersections.
D. 
Within 100 feet of an intersection right-of-way, streets shall be approximately at right angles.
E. 
All street intersection corners shall be rounded by curves of at least 10 feet in radius at the property line.
F. 
Within triangular areas formed by the intersection of two street property lines and a third line joining them at points at a distance of 25 feet away from their intersection, visibility for traffic safety shall be provided by excavating, if necessary. Nothing in the way of fences, walls, hedges or other landscaping shall be permitted to obstruct such visibility.
A. 
Half streets shall be prohibited except where it is necessary to provide the remaining half of a previously approved half or narrow street.
B. 
Reserve strips controlling access to streets shall be prohibited except where their control is placed with the Town under conditions approved by the Planning Board.
A. 
Where a street does not extend to the boundary of the subdivision and its continuation is not needed for access to adjoining property, it shall be separated from such boundary by a distance not less than the minimum lot depth prescribed by the Zoning Ordinance.[1]
[1]
Editor's Note: See Ch. 125, Zoning.
B. 
Reserve strips of land shall not be left between the end of a proposed street and an adjacent piece of property. However, the Planning Board may require the reservation of a twenty-foot-wide easement to accommodate pedestrian traffic or utilities to the next street.
C. 
A circular turnaround shall be provided at the end of a permanent cul-de-sac street.
D. 
A circular turnaround shall be provided at the end of a temporary cul-de-sac street. Deed requirements for the temporary turnaround shall be in a form certified as satisfactory by the Town Attorney.
E. 
Cul-de-sac streets with divided pavements or center malls shall be prohibited.
A. 
The arrangement of streets shall provide for the continuation of existing streets between adjacent properties where such continuation is necessary for convenient movement of traffic, effective fire protection, efficient provision of utilities and where such continuation is in accordance with the Master Plan.
B. 
If the adjacent property is undeveloped and the street must be a dead-end street temporarily, the right-of-way and improvements shall be extended to the property line. A temporary circular turnaround of a minimum of 50 feet in radius shall be provided on all temporary dead-end streets, with the notation on the plat that the land outside the street right-of-way shall revert to abutting lots whenever the street is continued.
C. 
The Planning Board may limit temporary dead-end streets to a length not more than double the permitted length of permanent cul-de-sac streets.
All streets shall be named, and such names shall be subject to the approval of the Planning Board. Names shall be sufficiently different in sound and in spelling from other street names so as not to cause confusion. A street which is a continuation of an existing street shall bear the same name.
[Amended 2-28-1989 by L.L. No. 2-1989; 9-16-2014 by L.L. No. 3-2014]
