Other improvements.
(1)
The Subdivision Committee may require a higher type of
pavement than specified in Table I or improvements in addition to those set
forth in the table where it deems such to be necessary because of prospective
traffic safety of pedestrians in connection with sidewalks or in order to
conform to conditions prevailing in the neighborhood, in which latter case
the neighborhood standard shall generally apply. Crosswalks may be required
when deemed necessary by the Subdivision Committee.
(2)
Subsurface drainage. Prior to placing the street surface,
adequate subsurface drainage for the streets and all subsurface utilities
as acceptable to the Committee shall be provided or installed by the subdivider.
The size of the storm drainage structures shall be computed by using Talbot's
Formula for runoff.
(3)
Slopes, Slopes of banks measured perpendicular to the
center line of the street shall not exceed three to one for fills and two
to one for cuts.
(4)
In all respects in which standards for required improvements
are not set forth herein or specified by the Subdivision Committee hereunder,
the applicable standard requirements of the Pennsylvania State Department
of Highways shall govern and all work shall be performed in the manner prescribed
in the standard specifications for road construction of said Department for
the type of construction under consideration.
C.
Approval, maintenance and security.
(1)
The work of constructing streets or roads, including
the construction methods and materials incident thereto, shall be subject
to the approval of the Borough Engineer. Final acceptance of the completed
streets or roads shall rest with the Borough Council. The subdivider shall
enter into a contract with the Borough Council which provides that, in consideration
of the acceptance of the roads or streets for inclusion in the Borough highway
system, the subdivider agrees to construct the roads or streets in the subdivision
to the standards prescribed herein at his own expense with no cost to the
Borough.
(2)
In the event that the owner or subdivider desires to
complete the construction of the streets after the plat is placed on record,
he shall be required to submit a cost estimate prepared by a registered professional
engineer, setting forth all items of work to be performed and the estimated
cost. Said estimate shall be subject to the approval of the Borough Engineer.
A certified check or contract performance bond issued by a surety company,
subject to the approval of the Borough Council, in an amount equal to the
approved estimate to ensure the completion of the work, shall be filed with
the Borough Council. All construction items shall be completed within one
year after the plat is placed on record, except where bituminous paving construction
is required. When bituminous construction is required, it shall be completed
within two years after the plat is placed on record.
(3)
The certified check shall be made payable to the Borough.
In the event that the work is satisfactorily completed within the time specified,
the certified check or surety bond shall be returned.
(4)
The owner or subdivider shall be required to maintain
all culverts, ditches, backslopes and shoulders on all streets for a period
of two years after their completion. All exposed surfaces on which a turf
or sod has not been developed shall be reseeded or sodded. An estimate of
cost shall be prepared by a registered professional engineer, setting forth
all items of work to be performed and the estimated cost. Said estimate shall
be subject to the approval of the Borough Engineer. The owner or subdivider
shall deposit with the Borough Council a certified check or performance bond
issued by a surety company in an amount not less than the cost of maintaining
said streets for a period of two years.
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.
A.
The subdivider shall provide the subdivision with a complete
water main supply system, which shall be connected to a municipal water supply
or to a community water supply system approved by the Borough Engineer and
the Pennsylvania State Department of Health, with satisfactory provision for
the maintenance thereof, except that, when such municipal or community water
supply is not available, the subdivider shall provide an individual water
supply on each lot in the subdivision in accordance with minimum standards
approved by the Pennsylvania State Department of Health.
B.
The plans for the installation of the mains of a water
supply system shall be prepared by the subdivider with the cooperation of
the applicable water utility company and approved by the Borough Engineer.
Upon the completion of the water supply installation, one copy each of the
plans for such system as built shall be filed with the Subdivision Committee.
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:
[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.
