1.
General design
standards.
A.
All utilities
shall be designed, laid out and constructed in accordance with the
requirements of the public utility companies or authorities that will
provide service to the land development and in accordance with all
applicable municipal, county, state and federal regulations, standards
and specifications.
B.
Utility systems
shall be coordinated with existing and proposed systems in adjacent
areas to assure sufficient capacity within logical service areas.
C.
Utility systems
shall be designed for full build-out of the area encompassed by a
preliminary land development plan, although actual construction may
occur in phases.
D.
All underground
utilities serving new subdivisions or land developments (including
water lines; sanitary sewerage; storm sewers when in enclosed pipes;
natural gas; and electric, telephone and other telecommunications),
shall be placed in utility easements within street right-of-way but
outside of the paved cartway. Where such location is not feasible,
utilities may be placed below the paved cartway or may be placed in
permanent easements located along rear parcel boundaries or in other
locations where they will cause minimal disruption of desirable building
arrangements and where future maintenance can be accomplished with
minimal disturbance of site improvements and activities. If the new
subdivision or land development abuts existing easements or public
rights-of-way where overhead electric or telephone distribution supply
lines and service connections exist, service shall be supplied from
those overhead lines, and from that point of connection shall be placed
under the paved cartway or shall be installed underground within permanent
easements or rights-of-way. All easements shall be of sufficient width
to allow access for maintenance. Electrical distribution shall comply
with Order No. 99 of the Pennsylvania Public Utility Commission (PUC).
2.
Water supply
system.
A.
Potable water
shall be supplied to every development parcel and building within
a land development in accordance with standards and specifications
of the Western Pennsylvania-American Water Company, Allegheny County
and applicable state and federal regulations. The capacity of the
system shall be adequate to handle the necessary peak flows based
on complete development, including water needed for fire protection
as well as for all uses within the land development.
B.
A system of
fire hydrants shall be installed, with spacing as required to provide
minimum fire flows as recommended by the American Insurance Association
and the National Board of Fire Underwriters.
C.
A water supply
distribution system shall be designed to assure minimal disruption
of service in case of breaks, and provision shall be made for service
by an alternate source of supply if the primary supply is disrupted.
3.
Sanitary sewage
facilities.
A.
Every development
parcel and building within a land development shall be served by a
system of sanitary sewers connected with an approved sewage treatment
facility.
B.
To the maximum
extent feasible, sanitary sewer systems shall be designed to serve
drainage areas. All sewers shall be sized to handle peak flows at
full development.
C.
Sanitary sewers
shall be laid out and constructed in accordance with all applicable
regulations of the Borough, Allegheny County and the Commonwealth
of Pennsylvania.
4.
Stormwater management
facilities.
A.
All stormwater
flowing over a subdivision or land development site shall be managed
to assure that the maximum rate of stormwater runoff is no greater
after development than prior to development; or to manage the quantity,
velocity and direction of resulting stormwater runoff in a manner
which otherwise adequately protects health and property from possible
injury.
B.
The quality
of all stormwater runoff and any other nonpoint discharges from a
land development site shall be in accordance with all applicable regulations
of federal, state and county governments.
C.
For land developments
located in areas for which watershed stormwater management plans have
been prepared and adopted by Allegheny County under the provisions
of the Pennsylvania Storm Water Management Act,[1] stormwater shall be managed in accordance with the precise
standards of the adopted plan and any municipal regulations enacted
pursuant thereto.
[1]
Editor's Note: See 32 P.S. § 680.1
et seq.
D.
For land developments located in areas for which watershed stormwater management plans have not yet been prepared and adopted, stormwater runoff shall be analyzed and managed in accordance with the procedures and standards contained in Chapter 4 of Stormwater Management Guidelines and Model Ordinances, published by the Pennsylvania Department of Environmental Protection and in accordance with the following:
(1)
Stormwater
management facilities shall be designed to control peak rates of discharge
for the one-hundred-year storms as are determined by the Municipal
Engineer to be appropriate, based on the capacity of existing obstructions
and system components.
(2)
The predevelopment
and post-development hydrographs shall match for all design storms,
except:
(a)
If a
land development discharges directly into the Monongahela River, post-development
runoff may be discharged at an accelerated rate, provided that the
discharge will not cause riverbank erosion and provided further that
the discharge does not contain any pollutant discharge prohibited
by county, state or federal regulations.
[Amended 12-10-1992 by Ord. No. 1031]
Each lot shall have frontage on a public street, as defined by this chapter, which is constructed in accordance with the design standards of Part 7 and the Borough Public Improvements Code,[1] unless an exception or modification to this requirement is granted in accordance with the provisions of Part 9 of this chapter.
