A. 
The arrangement, character, extent, width, grade and location of all streets shall conform to the Official Map of the Borough. Where streets are not shown on the Official Map, the arrangement and other design standards of streets shall conform to the provisions set forth herein. Every subdivision shall have access to a public street, except as may be otherwise authorized herein.
B. 
The purpose of this article and all of its subsections now or hereafter adopted is to regulate new street and road construction in order to protect the safety and health and to provide for the general welfare of the Borough and its inhabitants by providing procedures and specifications for street and roadway construction within the Borough.
A. 
In general, all streets shall be continuous and in alignment with existing streets and shall compose a convenient system to ensure circulation of vehicular and pedestrian traffic.
B. 
Where a subdivision abuts or contains an existing or proposed street, the newly proposed streets shall be planned and designed in order to protect residential areas from heavy traffic and also to provide separation between local and through traffic.
C. 
Streets shall be logically related to the topography so as to produce usable lots and reasonable grades.
D. 
Half or partial streets shall not be permitted. Wherever a tract to be subdivided borders an existing half or partial street, the remaining portion of the street shall be platted within such tract.
E. 
Dead-end streets shall be prohibited except as stubs utilizing temporary culs-de-sac to permit future street extension into adjoining tracts of ground or when designed as permanent culs-de-sac of less than or equal to 1,000 feet in length serving no more than 50 lots. Culs-de-sac shall be a minimum of 250 feet in length, measured from the center line of the intersecting street to the midpoint of the cul-de-sac. The paved turnaround must have a minimum radius of 40 feet (eighty-foot diameter) and a right-of-way radius of 50 feet (one-hundred-foot diameter). Where the intersection of more than one cul-de-sac is proposed, the maximum length of any section from point of origin and through street shall not exceed 1,000 feet in length or serve more than 50 units.
F. 
Where a street is proposed to be extended into property proposed for future development, a temporary hammerhead turnaround shall be provided in an extension of the right-of-way onto the property proposed for future development. The extension of the right-of-way containing the hammerhead turnaround shall not include any portion of frontage for a residential lot.
G. 
Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall make provision for the proper projection of streets. Where a new subdivision adjoins unsubdivided land capable of future subdivision, then the new streets shall be carried to the boundaries of the tract proposed to be subdivided.
H. 
Streets shall be laid out to intersect as nearly as possible at right angles; in any event, no street shall intersect another at less than 70°. Intersections of more than two streets shall be avoided. Where this proves impossible, such intersections shall be designed with care for safety, and suitable curbs, barriers, signs and other devices may be required. Streets entering opposite sides of another street shall be laid out directly opposite one another.
I. 
Street intersections shall not be so numerous or so close to each other as to impede the flow of traffic or as to create a safety hazard.
J. 
Clear sight triangles shall measure a minimum distance of 75 feet along street center lines from their point of junction at all intersections unless longer distances are required to provide adequate sight distance; no structures or other obstructions to vision shall be permitted. A clear sight triangle is defined as an area of unobstructed vision at street intersections defined by lines of sight between points on the center lines at a given distance from the intersection of street lines.
K. 
The vacation of any street or part of a street dedicated for public use shall not be approved if such vacation interferes with the uniformity of the existing street pattern or any future street plans prepared for the area.
L. 
A design speed of 30 miles per hour shall be utilized unless traffic patterns and volumes dictate an increase. Said increase shall be as approved by the Borough Engineer.
M. 
If undeveloped property has an alternative means of vehicular access, a single-family lot in an adjoining recorded plan shall not be used as a future right-of-way for a public street, private street or other vehicular access.
N. 
These regulations shall apply to all streets and roads shown on plats of residential subdivision containing four lots or parcels or more and for all roads and streets shown on plats of subdivision of business, commercial or industrial properties, regardless of the number of lots shown thereon.
O. 
In subdivisions of residential properties containing three lots or fewer, an exception may be granted by Borough Council wherein private drives shown on laid plats may be built to a lesser standard than that of the provisions herein only if said private drives are to be privately owned and maintained and are not to be dedicated to the Borough. In that event, Council will establish such lesser standards subject to conditions of ground and character of the development. Furthermore, whenever a plat of residential subdivision depicts three lots or fewer, and the streets thereon are to be privately owned and maintained and not dedicated to the Borough, no further subdivision of the land area shown thereon shall be permitted, and such restriction shall be marked on the residential subdivision plat.
P. 
All streets shall also conform to the requirements of the Westmoreland County Subdivision and Land Development Ordinance. Where the requirements of these specifications and the county ordinance conflict, the provisions herein will prevail.
A. 
Profiles. No street grade shall be less than 1% and shall not exceed 10% for any collector streets or roadways and 14% for any local streets and roadways in the Borough. Streets shall have a grade not to exceed 5% for a distance within 50 feet of the street right-of-way line for any intersecting street.
B. 
Cross section. The gradients of streets shall be 0.02 foot per foot, and the cross section shall conform to the dimensions and depths as set forth on Detail No. 1, Typical Street Section, as the same is attached hereto and made a part hereof by reference.[1]
