(a) All lots to be platted shall have access to a street, and all proposed streets shall be installed or financially guaranteed as provided in section 28-34, and in accordance with the requirements below, prior to final plat approval.
(b) All streets shall be designated as either public or private on both the preliminary and final plats. If streets are designated as private, the developer shall submit a written statement with the preliminary plat specifying plans for ownership and maintenance of said streets. In addition, said statement shall appear on the original of the final plat in such a manner that it will be legible on any copies made therefrom. If streets are designated as public, the town may, by resolution, in accordance with section 28-37, accept said streets for ownership and maintenance. If requested by the developer and at the option of the town council, streets may be accepted by the town for ownership and maintenance in stages as planned by the developer in order to save undue expense to the developer as well as the town. The town council may, at its option, delay acceptance of a street for up to one year from completion to establish the quality of the construction. In no case will the streets be accepted for ownership and maintenance by the town until the following minimum standards have been met or financially guaranteed as provided in section 28-34(b). All public and private streets shall meet the following minimum standards:
(1) Development standards.
Street Type | Right-of-Way | Travelway Width | Surface Material |
Temporary construction road | None | 12' | Gravel |
Lane | 30' | 16' | Gravel |
Minor street | 40' | 18' | Pavement |
Collector street | 50' | 20' | Pavement |
Arterial street | 60' | Per state D.O.T. standards | |
(2) All grading and ditching shall be done to meet town specifications.
(3) All drainage pipe shall be installed at the expense of the developer. The pipe size shall be determined by the town, but in no case will anything less than 15-inch pipe be permitted.
(4) The amount of right-of-way to be graded may vary depending on the drainage method selected by the developer. For standard double-ditch drainage, it will be necessary to clear a minimum of 32 feet from ditch to ditch. When alternative drainage methods are used (i.e., curb and gutter, drainage to one side of the road, inverted crown road, etc.) grading of less than 32 feet may be possible. See section 28-190 for illustrations of drainage methods.
(5) Curb and gutter is optional, but the town would encourage that it be installed. Total cost of curb and gutter is to be paid by the developer.
(6) All classes of streets except temporary construction roads shall have stabilized shoulders of at least three feet in width on each side of the travelway.
(7) Within 14 days after road grading and excavation work has been completed, all banks, shoulders (if grass) and ditches created shall be seeded by the developer to prevent erosion and to cover ecological scars.
(8) On any banks or shoulders seeded in subsections (b)(6) and (7) of this section, continued effort must be made by the developer to establish a good growth of grass and to take any action necessary to prevent erosion until a good grass growth is established.
(c) (1) An approved turn around shall be provided where access is a dead-end. The town encourages use of a cul- de-sac for such a turn around. Minimum paved radius for a cul-de-sac is 40 feet to allow for adequate turning room for emergency vehicles. Alternative turn around styles, including T-shaped and Y-shaped turn arounds, will be considered but must be approved by the town fire coordinator.
(2) A temporary turn around, temporary for no more than 12 months, shall be installed on any street which will later be extended. The 12-month period may be extended upon request of the developer and approval of the subdivision administrator. If permission to extend this period is not sought or is not given, the turn around must be converted to a permanent turn around which meets the minimum requirements. At a minimum, the temporary turn around shall consist of six inches of compacted stone and shall provide adequate turning room for emergency vehicles. See section 28-191 for examples and dimensions of permanent and temporary turn arounds.
(3) Where the combined width of paving and stabilized shoulders required by this section is determined to be impractical due to topographical or other extreme physical conditions, the zoning and planning board may authorize a lesser width after special review.
(4) Street paving shall consist of a six-inch compacted stone base and two-inch I-2 bituminous plant mix. Lanes shall have not less than two inches of compacted gravel. Temporary construction roads shall have not less than four inches of compacted ballast stone.
(5) The total cost of paving shall be paid by the developer. The paving may be arranged by the developer, with the contract being approved by the town, or, should the developer request, paving may be arranged by the town.
(6) The grade of roads shall not exceed 15 percent because of the difficulty of operating vehicles on such a steep road and the high potential for erosion of the travelway and ditches. Provided, however, roads may exceed a 15 percent grade only after review by the fire coordinator and approval of the zoning and planning board. Where possible, to avoid environmental impact, yet commensurate with safety, roads should be constructed along the contour of the land to avoid steep grades.
(7) At the option of the town council, streets and roads may be accepted as part of the town's street system provided they have been paved to the standards in this section or the developer has submitted funds to the town for such paving as part of the improvements guarantee in accordance with section 28-34(b).
