(A) Conformity with master plan. Alignment of major streets shall conform as nearly as possible with that shown on the master plan of the town to be adopted by the Council.
(B) Relation to adjoining street system. The layout of streets shall provide for the continuation of principal streets existing in adjoining subdivisions, or of their proper projection when adjoining property is not subdivided. It shall provide also for future projection of streets into areas which presently are not subdivided.
(C) Minor streets. Minor streets which primarily serve to provide access to abutting properties only, shall be designed to discourage through traffic.
(D) Dead-end streets. Streets designed to have one end permanently closed (cul-de-sac) shall be no longer than 400 feet and shall be provided at the closed end with a turn-around having a minimum right-of-way radius of not less than 56 feet or with a “Y” or “T” permitting comparable ease of turning.
(E) Half streets. A street lying along the boundary of a subdivision may be dedicated one-half the required width if it is practical to require the dedication of the other half when the adjoining property is subdivided; and, wherever there exists a dedicated half-street of an adjoining plat, the half shall be dedicated on the proposed plat to make the street complete.
(F) Street alignment. Connecting street center lines deflecting from each other at any one point more than ten degrees shall be connected by a curve of at least 100 feet radius for minor streets and at least 300 feet radius arterial streets. A tangent at least 100 feet long shall be introduced between curves on arterial streets.
(G) Jogs at street intersections. Street jogs with center line off-sets of less than 125 feet shall be avoided.
(H) Street grades. Streets shall conform closely to the natural contour of the land, except where a differing grade has been established by the local governmental authorities or the agency furnishing municipal services to the town. Grades shall be not less than 0.50% for any street and not more than 6% for major streets or 10% for minor streets. Changes in grade shall be connected by easy vertical curves.
(I) Street widths. Street right-of-way shall not be less than as follows:
(1) Major and minor streets: 66 feet; and
(2) Short loop or cul-de-sac streets: 66 feet.
(J) Street names.
(1) Streets that are obviously in alignment with others already existing and named shall bear the names of the existing streets. Other streets shall not bear names that duplicate or phonetically approximate the names of existing streets.
(2) A street with a general north-south alignment shall be designated “Avenue”, one with a general east-west alignment shall be designated “Street”. A cul-de-sac street shall be designated “Court”. The designation “Way” shall be reserved for long, continuous streets with major thoroughfare characteristics. The designation “Boulevard” shall be reserved for long, continuous streets characterized by a broad right-of-way, tree and turn embellishment, and predominantly non-commercial traffic. Insofar as possible, new streets shall preserve and continue any alphabetical sequence and type of names already established in nearby subdivisions.
