Where the public sanitary sewer system, in the opinion of the Committee, is reasonably accessible, sanitary sewers shall be installed to adequately serve all lots with connections to the public system. Where lots cannot be served by the extension of an existing public sanitary sewer, the subdivider shall obtain approval of lot sizes as provided in §
211-15H hereof. In addition, individual septic tanks and disposal fields and/or neighborhood disposal systems shall be approved by the State Department of Health.
An adequate storm sewer system, consisting of inlets and other underground
drainage structures with approved outlets shall be constructed where the runoff
of stormwater and the prevention of erosion cannot be accomplished satisfactorily
by surface drainage facilities. Outlets shall be approved by the owners of
the properties affected and by the Subdivision Committee.
The curbs and gutters shall be constructed of cement concrete or stone
and may be of the following two types:
A. Plain cement concrete: Type A, Section 7.15 of the 1960
Pennsylvania Department of Highways Specifications, using a mix of 1:2 1/4:3.
B. Stone curb: Type A, Section 7.20 of the 1960 Pennsylvania
Department of Highways Specifications, six inches wide by 22 inches high by
six feet long.
[Amended 8-31-1987 by Ord. No. 943]
Sidewalks shall be installed and shall have a minimum width of four
feet, except that sidewalks serving apartment houses or proposed commercial
areas shall be wider if deemed necessary by the Subdivision Committee. Sidewalks
may be of the following two types:
A. Concrete, four inches in thickness, 1:2 1/4:3 placed
on four-inch sand, pea gravel, crushed stone or equivalent base material.
B. Bituminous concrete.
(1) Description. Bituminous surfaced sidewalks shall consist
of an approved bituminous concrete surfacing material placed on a crushed
stone base on a prepared foundation, between concrete or steel curbs placed
longitudinally on either side of the sidewalk or between an existing structure
and a concrete or steel curb.
(2) Foundation. The foundation for the base shall be formed
at a depth of six inches below and parallel to the finished surface of the
sidewalk, unless otherwise indicated on the drawings or specified. All soft
and yielding material or other unsuitable material shall be removed and replaced
with suitable material, and the foundation shall be compacted thoroughly and
finished to a smooth, firm surface.
(3) Placing base. If the sidewalk is placed between concrete
curbs or between an existing structure and a concrete curb, the base shall
be confined by the limiting structures. If steel curbs are used, the base
shall be constructed four inches wider on either side of the sidewalk than
the surface course. The base shall have a minimum depth, after compaction,
of four inches. The coarse material shall conform to Pennsylvania Department
of Highways Specifications for No. 3A stone. The fine material shall conform
to Pennsylvania Department of Highways Specifications for No. 1 stone. A layer
of fine material shall be placed on the foundation in the ratio of one cubic
yard of fine material to 36 square yards of foundation. The coarse material
shall be placed on the layer of fine material so as to distribute the coarse
material to the required depth for the full width of the base. After the coarse
material has been placed and spread, it shall be checked with a straightedge
or template and all irregularities corrected. The coarse material shall be
compacted by use of approved mechanical tampers, approved hand tampers, or,
in cases where sufficient width of sidewalk will permit, it may be compacted
by approved small rollers. In all cases, the compaction shall begin at the
sides of the sidewalk and work to the center. The compaction shall continue
until all of the coarse material is satisfactorily locked in place. After
the coarse material is satisfactorily compacted, the fine material for filling
voids shall be spread in a series of thin applications, parallel to the center
line of the sidewalk. The fine material shall be spread with a sweeping motion
of a square-pointed shovel and alternately in opposite directions, this process
continuing until no more material can be forced into the voids. Hand brooms
shall be used to spread the material over the surface to ensure even distribution
and filling of all voids in the coarse material. All excess filler material
forming in piles or cakes upon the surface shall be loosened and scattered.
Compaction shall be continued during the placing of the fine material and
in the areas where the fine material is being placed, and additional fine
material shall be applied where necessary to fill voids. After the completion
of the application and compaction of dry screening, the surface shall be sprinkled
with water and again compacted. All excess screenings formed in piles and
cakes shall be loosened and scattered by sweeping. The sprinkling and compaction
shall be continued until all voids are filled and a smooth, hard, monolithic
surface is obtained. After the base has been completed as described, the surface
shall be checked with an approved straight-edge or template. Any irregularities
that exceed 1/4 inch in the surface shall be remedied by loosening the surface
and adding or removing material as required, after which the entire area,
including the surrounding surface, shall be compacted until a satisfactory
surface is obtained.
(4) Curbs. Portland cement concrete curbs shall have a minimum
width of four inches and a minimum depth of 14 inches and shall be placed
so that the top of the curb is at the grade of the finished sidewalk. The
concrete shall consist of portland cement concrete of the following proportions:
six bags of cement per cubic yard of concrete, 200 pounds of fine aggregate
and 325 pounds of coarse (2B) aggregate per bag of cement. Steel curbs shall
have a minimum thickness of 1/4 inch and a minimum width of two inches and
shall conform to ASTM Designation A7 for copper steel. The steel shall be
straight and uniform. The steel curbs shall be placed on the prepared base,
secured by approved steel rods or pins the minimum diameter of which shall
be 1/2 inch and minimum length 14 inches, spaced not more than 10 feet apart
and driven through the prepared base and into the ground a sufficient depth
that the top of the rod or pin does not project above the top of the sidewalk.
The rods or pins shall be secured to the steel curb by welding or other approved
method. After the curbs are placed and the rods or pins securely fastened,
the steel curbs shall be coated on all exposed surfaces with approved bituminous
paint or primed before the surface course is placed against them.
(5) Surface course. The bituminous surface course shall consist
of one course of hot-laid asphaltic concrete, shall have a minimum depth of
two inches and shall conform to the Pennsylvania Department of Highways Specifications
for bituminous surface course FJ 1 in composition and application.
(6) Driveway sections. In driveway sections, the base course
shall conform to the Pennsylvania Department of Highways Specifications for
crushed stone base course in composition and application. The depth of the
base course in driveway sections shall be eight inches at a minimum. The sidewalk
in driveway sections shall be eight inches wider than the nominal width of
sidewalk, that is four inches on either side of the sidewalk center line.
Steel curbing shall not be placed in driveway sections unless indicated on
the drawings or specified.
(7) Backfilling. After the surface course has been satisfactorily
completed, the spaces adjacent to the sidewalk shall be backfilled with acceptable
material in layers of not more than four inches in depth and shall be compacted
mechanically to the required elevation and cross section.
Streetlights may be required when considered reasonable by the Subdivision
Committee. Fire hydrants shall be required wherever there is a water supply
system.
Upon the completion of the improvements in a subdivision, plans and
profiles of the same, as constructed, shall be filed with the Subdivision
Committee.
Required improvements shall be installed by the subdivider under the
supervision of the Borough Engineer.
