B. The entire right-of-way of each street in a proposed subdivision
shall be graded, and there shall be installed paving, drainage structures,
curbs and gutters and sidewalks in accordance with the appropriate
standards for the class of street, with the exception that the standards
of the high-density residential area may be used in a low-density
residential area.
C. Minimum curb or pavement-edge radii at street intersections shall
be 25 feet for intersections of a local street with another local
street or a local street with a collector street or a local street
with an alley; 30 feet for other intersections, or such greater radius
as is suitable to the specific intersection.
D. Where the grade of the street is above or below the grade of the
adjacent land, walls or slopes shall be constructed in a manner satisfactory
to the Borough Engineer and shall be sufficient to support the street
or the adjacent land, as the case may be.
E. Where the grade of the street is three feet or more above the grade
of the adjacent land, guardrails shall be built which shall be satisfactory
to the Borough Engineer.
F. Street shoulders shall be constructed with suitable materials from
roadway or structure excavation supplemented by additional suitable
material, if directed, from borrow excavation; the entire shoulder
area shall be uniformly and thoroughly compacted by rolling as directed
by the Borough Engineer.
G. The outside edge of sidewalks shall be placed one foot from the street
right-of-way lines; except for business streets, where the sidewalk
shall occupy the full width between the curb and the street right-of-way
lines.
H. Embankments at the sides of streets and cross sections of drainage
ditches shall not exceed a maximum slope of one foot horizontally
to one foot vertically in a cut section; and 1 1/2 feet horizontally
to one foot vertically in a fill section; in special cases the Borough
Engineer may require more rigid standards.
I. Means of ingress and egress for vehicles to and from each lot or
parcel shall be shown on the plans for installation in accordance
with existing Borough regulations for depressed curbs and driveways
across sidewalks.
J. Bituminous or macadam streets shall crown at the center line to a
slope of 1/4 inch to one foot; concrete streets shall crown at the
center line to a slope of 1/8 inch per foot; alleys shall be dished
to the center line at a slope of 1/4 inch per foot for bituminous
or macadam paving and 1/8 inch per foot for concrete paving.
K. Standards for construction.
(1) All streets, curbs, sidewalks, sanitary sewers and storm drainage
facilities shall be constructed conforming to and in accordance with
the Standards for Construction Specifications, prepared by Planning
Development Associates (January 1993).
(2) All streets, curbs, sidewalks, sanitary sewers and storm drainage
facilities along Main Street from its intersection with Miller Avenue
to its intersection with McKinley and Cambria Streets and along McWhinney
Street from its intersection with Main Street to its intersection
with Caroline Street shall be constructed conforming to and in accordance
with Construction Standards prepared by John C. Laatsch and Associates,
dated February 24, 1993.
A street sign having a metal nameplate shall be installed at
every street intersection and shall conform to existing Borough standards.
