Borough of Milton, PA Article IV Design Standards

§ 213-12 Streets.

The arrangement, character, extent, width, grade and location of all streets shall conform to the Official Map and to the Community Master Plan, if one has been adopted, and shall be considered in their relation to existing and planned streets, to topographical conditions and to public convenience and safety and in their appropriate relation to the proposed uses of the land to be served by such streets. Where not shown on the Official Map or Community Master Plan, the arrangement and other design standards of streets shall conform to the provisions found herein.

A. The arrangement of streets in new subdivisions and/or land developments shall make provisions for the continuation of existing streets in adjoining areas.

B. Where adjoining areas are not subdivided and/or developed, the arrangement of streets in new subdivisions and/or land developments shall make provisions for the proper projection of streets.

C. When a new subdivision and/or land development adjoins unsubdivided and/or undeveloped land appropriate for subdivision and/or land development, then the new streets shall be carried to the boundaries of the tract proposed to be subdivided and/or developed.

D. Alleys shall be discouraged in residential districts. In commercial and industrial areas, adequate alleys or off-street loading and unloading space, where needed for loading and unloading or access purposes, shall be provided.

E. The center lines of streets shall intersect as nearly at right angles as possible, but in no case shall they intersect at less than 75° nor more than 105°.

F. At intersections of streets and of streets and alleys, the property line corners shall be rounded by arcs with radii or by chords of such arcs in accordance with the engineering specifications.

G. Street jogs with center-line offsets of less than 125 feet shall be avoided.

H. Whenever the proposed subdivision and/or land development contains or is adjacent to a highway designated as a limited access highway by the appropriate highway authorities, provision shall be made for a marginal access street at a distance acceptable for the appropriate use of the land between the highway and such street.

I. To assure adequate sight distance, horizontal and vertical curves shall be provided on all streets and shall be 300 feet for primary streets, 200 feet for secondary and collector streets and 100 feet for minor streets.

J. Tangents. A tangent of at least 100 feet shall be introduced between curves on arterial and collector streets.

K. Street right-of-way widths shall not be less than as follows:

(1) Arterial streets: 80 to 120 feet.

(2) Collector streets: 60 to 80 feet.

(3) Minor streets: 60 feet.

(4) Marginal access streets: 50 feet.

(5) Alleys: 20 feet.

L. Dead-end streets, designed to be so permanently, shall not be longer than 400 feet and shall be provided with a turnaround having an outside road diameter of at least 80 feet and a property line diameter of at least 100 feet.

M. The grade of streets shall be not less than five-tenths percent (0.5%) nor more than 10% unless topographic conditions make a steeper grade necessary.

N. Names of new streets shall not duplicate existing or platted street names or approximate such names by the use of suffixes such as "lane," "way," "drive," "court" or "avenue." In approving names of streets, cognizance may be given to existing or platted street names within the postal delivery district served by the post office. New streets shall bear the same name of any continuation or alignment with an existing or platted street.

(1) Underground public utility facilities: 15 feet.

(2) Overhead public utility facilities: 10 feet.

(3) Drainage facilities: 20 feet.

B. Easements for public utilities shall, wherever possible, be centered on side or rear lot lines. Drainageways, channels or stream easements may be located as necessary to adequately meet the engineering requirements for the facility.

§ 213-14 Blocks.

Blocks shall not exceed 1,200 feet in length and shall be of sufficient width to permit two tiers of lots except as otherwise provided herein.

§ 213-15 Lots.

The arrangement and other design standards of lots shall conform to the following requirements:

A. Every lot shall abut a street.

B. Double-frontage lots shall not be platted, except that, where desired along limited access highways, lots may face on an interior street and back on such thoroughfares. In that event, a planting strip for a screen, at least 15 feet in width, shall be provided along the back of the lot. Where lots back on a railroad, creek or other natural barrier, there may also be required a fifteen-foot planting screen strip, and interior lots having frontage on two streets shall be prohibited except where unusual conditions make it desirable.

C. All lots shall conform to the minimum requirements of Chapter 243, Zoning, as to area and dimensions for the zones in which the subdivision and/or land development is located.
