[Amended 7-15-1993 by Ord. No. 1048]
A. The developer shall provide the most effective type of sanitary sewage
disposal consistent with the natural features, location, and proposed
development of the site. The following types of sanitary sewage disposal
are listed in order of preference:
(1) Connection to a public sanitary sewage disposal and treatment system.
(2) Provision by the developer of centralized sanitary sewage disposal
and treatment system, to be in accordance with the requirements of
the Pennsylvania Department of Environmental Protection.
(3) Capped sewers with temporary, approved on-lot facilities.
(4) On-lot sewage disposal systems consisting of septic tank with tile
field.
B. Connection to a public sanitary sewer system shall be required where
such a system can feasibly be provided to the proposed subdivision
tract and where such a system can adequately fulfill the sewage disposal
needs of the subdivision or land development.
C. Where a public sanitary sewer system is not yet accessible to the
site, but is planned for extension to the subdivision within a ten-year
period, the developer shall install sewer lines, including lateral
connections as may be necessary to provide adequate service to each
lot when connection with the sewer system is made. The sewer lines
shall be suitably capped at the street right-of-way line. When capped
sewers are provided, on-site disposal facilities shall also be provided.
Design of the capped system shall be in accordance with the standards
of the Pennsylvania Department of Environmental Protection and shall
be subject to the approval of the Borough Engineer.
D. Where a public sanitary sewer system cannot feasibly be provided
to the proposed subdivision tract or is not planned for extension
to the proposed subdivision tract, the Borough Planning Commission
may require the submission of a sewage feasibility report by the subdivider.
Such a sewage feasibility report must be prepared by a registered
engineer.
E. Where a private centralized sanitary sewage disposal and treatment
system is to be provided by the developer, a statement shall be submitted
to the Borough Planning Commission and the Joint Planning Commission
from the Pennsylvania Department of Environmental Protection certifying
that a permit has been issued approving the proposed facilities. Proof
of adequate provision for the operation and maintenance of the treatment
plant shall be furnished to the Borough Planning Commission. The system
shall be approved by the Pennsylvania Utility Commission where applicable.
F. In subdivisions where neither connection to a public sewerage system
nor a centralized sanitary sewer system is required, sewage disposal
shall be provided on individual lots, consisting of septic tanks and
tile absorption fields. The physical features of the tract on which
on-lot disposal is provided shall meet the criteria established by
the Department of Environmental Protection for on-lot sewage disposal
systems.
G. All new developments of three lots or more require that the Borough
revise its official sewage plan under the Sewage Facilities Act (Act
537, as amended). A revision to the official sewage plan shall not be required
where the plan adequately meets the sewerage needs of the proposed
development. The Borough shall submit a Plan Revision Module for Land
Development to the Pennsylvania Department of Environmental Protection
in order to determine whether a plan revision is necessary.
[Amended 7-15-1993 by Ord. No. 1048]
The developer shall provide a water supply and distribution
system to service the proposed subdivision through one of the following
methods listed in their order of preference:
A. Connection to a public water supply system where such a system can
feasibly be provided to the proposed subdivision tract and where the
capacity of such a system can adequately fulfill the water supply
demands of the proposed subdivision. A distribution system shall be
designed to furnish an adequate supply of water to each lot. A copy
of the approval of such a system by the appropriate public authority
or utility company shall be submitted with the final plan.
B. Where a public water supply system cannot feasibly be provided to
the proposed subdivision and where the average residential lot size
is to be less than 20,000 feet, or where a public water supply system
is planned to serve the proposed subdivision area within 10 years,
a private centralized water supply system will be provided by the
developer. If such a system is provided, it shall be approved by the
Pennsylvania Department of Environmental Protection and suitable agreements
shall be established for the ownership and maintenance of the system.
Also, such a system shall be designed and constructed in a manner
that would permit adequate connection to a public water supply system
in the future. Fire hydrants shall be provided in all centralized
water supply systems which will serve more than 25 lots or dwelling
units.
C. If water is to be provided by means other than private wells owned
and maintained by the individual owners of lots within the subdivision
or development, applicants shall present evidence to the Borough Council
that the subdivision is to be supplied by a certified public utility,
a bona fide cooperative association of lot owners, or by a municipal
corporation, authority or utility. A copy of a Certificate of Public
Convenience from the Pennsylvania Public Utility Commission or an
application for such certificate, a cooperative agreement or a commitment
or agreement to serve the area in question, whichever is appropriate,
shall be acceptable.
D. Where individual on-lot water supply systems are to be utilized,
they shall conform to the criteria established by the Borough of Northampton.
[Amended 7-15-1993 by Ord. No. 1048]
A. Storm drainage systems shall be provided in order to:
(1) Permit unimpeded flow of natural watercourses.
(2) Ensure adequate drainage of all low points along the line of streets.
(3) Intercept stormwater runoff along streets at intervals related to
the extent and grade of the area drained.
(4) Provide positive drainage away from on-site sewage disposal.
(5) Take surface water from the bottom of vertical grades to lead water
from springs and to avoid excessive use of cross-gutters at street
intersections and elsewhere.
B. General requirements.
(1) A site drainage plan for the proposed subdivision tract shall be
prepared which illustrates the following information:
(a)
Mapping of the watershed area or areas in which the proposed
subdivision is located.
(b)
Calculations of runoff for all points of runoff concentration.
(c)
Complete drainage systems for the subdivision. All existing
drainage features which are to be incorporated in the design shall
be so identified. If the subdivision is to be developed in stages,
a general drainage plan for the entire subdivision shall be presented
with the first stage and appropriate development stages for the drainage
system shall be indicated.
(2) The existing points of natural drainage discharge onto adjacent property
shall not be altered without the written approval of the affected
landowners.
(3) No stormwater runoff or natural drainage water shall be so diverted
as to overload existing drainage systems, or create flooding or the
need for additional drainage structures on other private properties
or public lands, without approved provisions being made by the developer
for properly handling such conditions.
(4) Storm drainage facilities should be designed not only to handle the
anticipated peak discharge from the property being subdivided, but
also the anticipated increase in runoff that will occur when all the
property at a higher elevation in the same watershed is fully developed.
(5) Where a subdivision is traversed by a watercourse, there shall be
provided a drainage easement conforming substantially with the line
of such watercourse, and of such width as will be adequate to handle
the unimpeded flow of a fifty-year design storm.
(6) Drainage structures that are located on state highway rights-of-way
shall be approved by the Pennsylvania Department of Transportation
and a letter from that office indicating such approval shall be directed
to the Borough Planning Commission.
(7) All streets shall be so designed as to provide for the discharge
of surface water from their rights-of-way. The slope of the crown
on proposed streets shall be not less than 1/8 of an inch per foot
and not more than 1/3 of an inch per foot.
C. Calculation of storm runoff. Storm runoff should generally be calculated
by the rational method as described in Manual Number 37 of the American
Society of Civil Engineers and in accordance with requirements of
the Borough Engineer. Complete detailed calculations shall be submitted
to the Borough Engineer. When the development is located in a large
watershed, alternative methods of runoff calculations, such as the
Natural Resources Conservation Service method, should be used in place
of the rational method.
