Street rights-of-way shall be measured from lot line to lot line. The minimum width for the right-of-way of a new street shall be 50 feet, unless reduced by the Board of Trustees and/or the Planning Board. The continuation of an existing street shall be at the same width as the existing street unless a different width is required by the Planning Board.

Where a development adjoins or includes existing streets that do not conform to the width of 50 feet and it is determined by the Board of Trustees and/or Planning Board that a future widening of the existing streets may be appropriate, the new streets shall be designed with a right-of-way width to accommodate the future widening.

The layout of new streets shall favor connectivity with the existing street network for vehicles, providing through traffic where practicable.

Local streets shall generally be designed such that grades do not exceed 10%. No street shall have a grade less than 1%. Maximum grades within 100 feet of intersections shall generally be 4%. The cross section of the paved surface from the center line to the curbline or edge of paving shall not exceed a three-percent slope.

Intersecting street center lines shall generally not be less than 75°. The distance between intersecting streets shall generally have a minimum offset of 125 feet from closest curb to closest curb. Approaches to all intersections shall generally follow a straight line for at least 100 feet measured along the curb. No more than two street center lines shall meet or intersect at any one point, unless the intersection is designed as a roundabout or existing site conditions dictate. Intersections shall be rounded at the curbline, with a curbline radius based on the street with the largest radius: principal arterials at 30 feet; minor arterials at 25 feet; and collector and local streets at 15 to 20 feet.

Dead-end or cul-de-sac streets longer than 250 feet shall provide a circular turnaround at the end with a radius of generally not less than 40 feet for the paved width and 50 feet for the right-of-way width, and tangent whenever possible to the right side of the road. Dead-end or cul-de-sac streets 250 feet long or less shall have a T- or Y-shaped turnabout 60 feet wide as an alternative to a circular turnabout. If a cul-de-sac street is of a temporary nature, a similar turnaround shall be provided and provisions made for future extensions of the street and reversion of the excess right-of-way to the adjoining properties.

Dead-end or cul-de-sac streets longer than 400 feet shall generally have a minimum paved width of 30 feet and shall provide a mountable curb on both sides of paving. A clear passage of five feet in the right-of-way shall be maintained outside of both curbs.

Sidewalks shall generally be provided to enhance pedestrian connectivity throughout the Village. Where dead-end streets are permitted, a walking path from the dead end to the other streets and to established walking trails shall be provided where practicable to facilitate pedestrian connectivity.

All developments shall be served by paved streets.

The pavement design shall be the responsibility of the developer and shall be based upon traffic loading projections and field sampling and laboratory analysis of the subgrade soils in the proposed streets. The design shall follow current recommendations of the Asphalt Institute, the Portland Cement Concrete Association or such other generally recognized standards as may be acceptable to the Superintendent of the Department of Public Works. Pavement shall be of one type throughout the development and be either bituminous concrete flexible pavement or portland cement concrete rigid pavement, except that, where existing concrete roadways are being widened, the widened pavement shall be portland cement concrete and the remaining pavement in the development may be either bituminous or cement.

Where subbase conditions are wet, springy or of such nature that surfacing would be inadvisable without first treating the subbase, these areas shall be excavated to a depth of at least 12 inches below the proposed subgrade and filled with a suitable subbase material, such as sand, gravel or stone, as determined by the Superintendent of the Department of Public Works. Where required by the Superintendent, a system of Type F underdrains shall be constructed beneath the surface of the paving and connected to a suitable drain. After the subbase material has been properly placed and compacted, the surfacing material shall be applied if the Superintendent of the Department of Public Works determines that the subbase is stable.

Subbase and/or aggregate base courses.

Bituminous base courses.

Bituminous pavements. Bituminous pavements shall consist of a bituminous concrete surface course — fine aggregate bituminous concrete mixed with asphalt. The bituminous pavement wearing surface shall generally not be installed until just prior to the time the streets are prepared for final acceptance. Prior to the installation of a bituminous concrete surface, the bituminous base course shall be inspected by the Superintendent of the Department of Public Works or his designee. Any areas of the base course in need of repair shall be removed and replaced at the discretion of the Superintendent of the Department of Public Works. If the Superintendent directs, a leveling course of FABC material shall be placed on any uneven or below grade base courses prior to the placement of finished pavement. Pavement surfaces shall be placed only with permission of the Superintendent of the Department of Public Works.

Alternate pavement types. If alternate pavement types are proposed either for decorative purposes, physical restrictions, existing conditions or shortages in certain construction materials, a detail of the type and/or location of alternate pavement types shall be submitted for approval. Approval shall be based upon the equipment, materials and methods proposed for use and the Superintendent of the Department of Public Work's inspection, testing and approval of a section of such pavement. If the Superintendent of the Department of Public Works does not approve the sample section of pavement, the developer shall replace it with permitted pavement.

Ten-year-storm criteria for low points with a relief swale.

Twenty-five-year-storm criteria for flow carried in pipes.

One-hundred-year-storm criteria for all culvert designs.

The Rainfall Intensity = Duration = Frequency Curves, published by the United States Department of Commerce, Weather Bureau, shall be used in the above computation.
