SECTION IV: DESIGN STANDARDS
Streets
Location and Alignment
1. 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.
2. The proposed subdivision shall conform, so far as practicable, to the current Master Plan as adopted as whole or in part by the Planning Board.
3. Provision satisfactory to the Planning Board shall be made for the proper projection of streets, or for access to adjoining property which is not yet subdivided.
4. 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.
5. Street jogs with minimal centerline offsets shall be reviewed for approval by the Town Engineer.
6. The minimum centerline radii of curved streets shall be one hundred feet. Greater radii may be required for principal streets.
7. All intersections of ways shall be at an angle of 90 degrees, if possible, otherwise at such an angle as the Planning Board may approve. The number of ways converging upon any one point shall be kept to a minimum. All intersections of ways shall be rounded with a curve at each corner having a radius of at least thirty feet unless the Board shall approve otherwise.
8. Property lines at street intersections shall be rounded or cut back to provide for a curb radius of not less than thirty feet.
Width
a. The minimum width of street rights-of-way shall be forty-four (44) feet. This forty-four feet shall include the street (twenty-eight feet) bounded on each side by granite curbs (6"), grass strips (18") and sidewalks (6'). The Planning Board may, at its discretion, allow the substitution of landscaping (grass, trees, etc.) for the sidewalk on one side of the right-of-way. Greater width shall be required by the Planning Board when deemed necessary for present and future vehicular travel.
9. Curb faces shall be located not closer than twenty-eight feet face to face or at greater widths required by the Planning Board.
Dead End Streets
10. Dead end streets shall not be longer than five hundred (500) feet.
11. Dead end streets shall be provided at the closed end with a turnaround having an outside roadway diameter of at least one hundred (100) feet.
Easements
Easements for utilities across lots or centered on rear or side lot lines shall be provided where necessary and shall be at least twenty (20) feet wide.
Where a subdivision is traversed by a water source, drainage way, channel or stream, the Planning Board shall require that there be provided a storm water easement or drainage right-of-way of adequate width to conform substantially to the lines of such water course, drainage way, channel or stream, and to provide for construction or other necessary purposes.
Open Space
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 shall by appropriate endorsement on the plan require that no building be erected upon such park or parks without its approval.
Protection of Natural Features
Due regard shall be shown for all natural features, such as large trees, water courses, scenic points, historic spots and similar community assets. Trees remaining within the subdivision shall be protected from mechanical injury during construction and from adverse changes or excavations as recommended in U.S. Department of Agriculture Bulletin 104 (April, 1965).
