Location and alignment.
All streets in the subdivision shall be designed so that, in the opinion of the Planning Board, they will provide safe vehicular travel. Due consideration shall also be given by the subdivider to the attractiveness of the street layout in order to obtain the maximum livability and amenity of the subdivision. Curvilinear street design will be encouraged.
The proposed streets shall conform, so far as practicable, to the Master or Study Plan as adopted, in whole or in part, by the Planning Board.
Provisions satisfactory to the Planning Board shall be made for the proper projection of streets for access to adjoining property which is not yet subdivided.
Reserve strips prohibiting access to streets or adjoining property shall not be permitted, except where, in the opinion of the Planning Board, such strips shall be in the public interest.
Street jogs with center-line offsets of less than 125 feet should be avoided.
The minimum center-line radii of curved streets shall be 100 feet. Greater radii may be required for principal streets.
Streets shall be laid out so as to intersect as nearly as possible at right angles. No street shall intersect any other street at less than 60°.
Property lines at street intersections shall be rounded or cut back to provide for a curb radius of not less than 20 feet.
All ways shown on a preliminary plan shall be named in pencil and shall have names rather than numbers or letters (such as First Street or Avenue A). Names shall be substantially different from names of other ways in Dalton or adjoining communities.
Width. The minimum width of a street right-of-way shall be 50 feet. Greater width may be required by the Planning Board when deemed necessary due to anticipated vehicular traffic or other considerations.
Grade. Grades of streets shall be not less than 0.5%. Grades shall be not more than 5.0% for major streets nor more than 8% for collector streets. The grade of a street within 50 feet of a street intersection shall not exceed 1.0% to provide a level area for traffic safety.
Dead-end streets. Dead-end streets shall not be permitted unless, in the opinion of the Planning Board, a dead end is necessitated by topography or other local conditions. If a dead-end street is necessary, then the following conditions shall apply:
Dead-end streets shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 100 feet, and a property line diameter of at least 120 feet.
At the end of a dead-end street, the Board may require reservation of an easement to provide for the continuation of a street, pedestrian traffic and/or utilities.
Easements for utilities across lots or centered on rear or side lot lines shall be provided where necessary and shall be at least 12 feet wide.
Where a subdivision is traversed by a watercourse, drainageway, channel or stream, the Planning Board may require that there be provided a stormwater easement or drainage right-of-way of adequate width to conform substantially to the lines of such watercourse, drainageway, channel or stream, and to provide for construction or other necessary purposes.
Before approval of a plan, the Planning Board may also, in proper cases, require the plan to show a park or parks suitably located for playground or recreation purposes or for providing light and air. The park or parks shall not be unreasonable in area in relation to the land being subdivided and to the prospective uses of such land. The Planning Board may, by appropriate endorsement on the plan, require that no building be erected upon such park or parks without its approval for a period of three years.
Due regard shall be shown for all natural features, such as large trees, stone walls or fences, watercourses, scenic points, historic spots and similar community assets, which, if preserved, will add attractiveness and value to the community. The developer shall make every attempt to adapt his subdivision to the site with a minimum of cutting and filling operations. The depth of the cut or fill, in the opinion of the Planning Board, shall not lower or raise the grade to the extent that the grade shall be significantly different from the surrounding neighborhood.
