§ 143-13. Streets., Article III. Design Standards, Chapter 143. Subdivision of Land, Part II. General Legislation, Code of Ordinances, Malta

General. Streets shall follow low land whenever feasible. When a subdivision street intersects an existing street, the Board may require the owner to improve the existing street as necessary to meet the requirements of these regulations for intersection design.

(Reserved)

Editor's Note: Former Subsection B, street width, was repealed 12-5-2011 by L.L. No. 12-2011. See now Ch. 139, Art V.

Design speed.

(1)

Town of Malta Streets and Roads shall have a minimum design speed of 40 miles per hour. The Town may determine, during site plan review, that a higher design speed is warranted. This minimum design speed is established in anticipation of the completed and adopted Town street or road receiving a speed limit posting of 30 miles per hour.

(2)

If a higher posted speed limit is considered by the Town to be appropriate, the Town-designated engineer, or other duly appointed Town agent or official shall recommend a commensurate increase in design speed.

(3)

Horizontal and vertical alignments shall be in accordance with the latest version of AASHTO "A Policy on Geometric Design of Highways and Streets" (Green Book).

Street intersections.

(1)

T intersections shall be used in residential areas where practical. Intersections of more than two streets shall be prohibited. Intersecting streets shall be laid out so as to intersect at 90°, if feasible. An angle of intersections of less than 75° shall not be permitted. Any change in street alignment to meet this requirement shall be at least 100 feet from the pavement edge of the intersecting street.

(2)

Street right-of-way lines and roadways at intersections shall be rounded with a radius determined from the following table by the higher type of street in the intersection:

Street Type	Minimum Right-of-Way Radius (feet)	Minimum Roadway Radius (feet)
Arterial	Varies	Varies
Collector	28	40
Local	10	25
Marginal access	5	20

(3)

The radii given are for ninety-degree intersections, and shorter radii at obtuse angles and greater radii at acute angles may be required. Intersections with arterial streets shall be held to a minimum and preferably spaced at least 1,000 feet apart.

(4)

Streets entering opposite sides of another street shall be laid out either directly opposite one another or with a minimum offset of 125 feet between their center lines.

(5)

Street lighting shall be provided at the intersection of subdivision streets with existing arterial streets.

Dead-end streets.

(1)

Dead-end streets shall not be longer than 800 feet and shall be provided with a turnaround at the closed end having a street right-of-way diameter of at least 166 feet and an outside edge of pavement diameter of at least 128 feet. If an island is left in the turnaround, it shall be nearly level to facilitate snow plowing and there shall be no curbs around the island. The turnaround pavement shall slope to the outside of the circle. The pavement radius at the entrance to the turnaround shall be at least 50 feet for symmetrical turnarounds and greater for offset turnarounds. When a street is extended beyond an intersection to make provision for its future extension, a temporary turnaround shall be provided at the end of the street unless no lots are served by the extension. The temporary turnaround shall meet the requirements for a permanent turnaround.

(2)

When a street is extended a distance greater than 800 feet beyond an intersection, a second means of access must be provided to the end of the street. Generally an intersection with a cross street which connects to another street within the subdivision is sufficient.

(3)

In the event that these additional roadways will not be constructed at the time the street is extended beyond 800 feet, an emergency access road shall be provided to ensure a second means of access. This emergency access road shall be designed in such a manner as to support emergency vehicles of 86,000 pounds gross vehicle weight, or current NFPA 1901 standard, but not less than Town highway design standards, and shall be maintained by the owner at his own expense. As such, proposed access road designs should be submitted to the Town for review and approval with the final submission and prior to final submission approval. The specific design requirements for this access shall depend upon the existing environmental conditions.

Street access. Access to arterial streets shall be restricted as far as practicable.

Street setbacks. Setbacks from existing street shall be in accordance with Chapter 167, Zoning. Fill slopes, shall be designed in accordance with the "Rural Street Section" and "Note 8" of the Town of Malta Standard Specifications for Roads and Highways, latest revision.

The width of the top of embankment shall be at least four feet wider than the width of pavements.

Guide railing. Where streets are constructed on fills of greater than 15 feet in height, guide railing shall be installed along the side of the road, eight feet from the edge of the pavement.

Rural roadway standard. A rural roadway standard may be used with the Planning Board's approval in subdivisions which meet the following design criteria:

(1)

Minimum/maximum area. The subdivision shall be limited to a size no less than 20 acres and no larger than 75 acres.

(2)

Number of residences. There shall be no more than 35 single-family homes in the subdivision. Duplexes, apartments, townhouses and other similar uses will not be permitted.

(3)

Lot size. No lot shall be less than 80,000 square feet, and the median lot size shall be greater than 100,000 square feet.

(4)

Lot dimensions. No lot shall have a width at the street line less than 250 feet. The width of the lots at the building line shall be equal to or exceed 250 feet.

(5)

Roadway. When using a rural roadway standard, the roadway geometry shall be designed to discourage through traffic. The roadway shall not be used as access to another subdivision, unless:

(a)

The other subdivision meets the same criteria as above.

(b)

The combined acreage of the two subdivisions is less than 75 acres.

(c)

There are less than 35 homes in total.

(6)

Rural roadway standard:

(a)

If a subdivision meets the required criteria, a rural roadway standard as shown in the typical detail may be used with the approval of the Planning Board.

(b)

The geometries of the roadway, vertical curves, horizontal curves, grades, etc., shall be subject to approval by the Planning Board.

The applicant for a subdivision will be required to install street signs and appropriate traffic control signs, including, but not limited to, stop signs, yield signs, and area speed limit or speed limit signs at the applicant's expense, with all such signs, and the placement of such signs, to be approved by the Town of Malta Highway Superintendent.
