The following standards shall be complied with in all subdivisions
or land developments in the municipality.
60.20.1.
Extension of facilities. In order to provide service for the
subdivision and land development or to relieve any facilities overburdened
by the development of the subdivision, Council may require that the
developer extend street, sewer or drainage facilities to intersect,
join, meet or be connected with existing street, sewer or drainage
facilities beyond the property being developed. It is the intent of
this section to encourage rational development of land within the
municipality, and to discourage isolated, spotty, or overextended
development which presents burdensome and excessive servicing costs
to the municipality. Nothing in this section shall be construed as
requiring Council to approve such development in the first instance.
60.20.2.
Lots. In general, sizes and shapes of lots shall be in conformity
with good planning. No subdivision plan will be approved by the Council
unless all lots whereon buildings are intended to be constructed shall,
in the opinion of the Council, be of such character that they can
be used for building purposes without danger to health or peril from
fire, flood, landslide or other hazard.
60.20.3.
Electric power service including distribution, service laterals
and streetlighting facilities shall be in accordance with current
Pennsylvania Public Utility Commission requirements. All costs for
streetlighting systems as required by municipal standards and established
by the power company servicing the plan, shall be borne by the developer.
60.21.1.
General.
1. All streets, when and wherever possible, shall connect with existing
roads so as to form one street and shall not be less in width than
such existing streets. All streets shall be graded to a minimum width
in accordance with the municipality standards herein referred to,
and all bridges, culverts and storm sewers shall be constructed for
the full width of the right-of-way of such streets or as specified
by the Municipal Engineer.
2. Where lots in a proposed subdivision or land development abut existing
streets whose right-of-way is less than Municipal standards, there
shall be dedicated for public use right-of-way width required to accommodate
any public improvements which are part of the subdivision or land
development approval.
[Amended 6-13-1994 by Ord. No. 6-13-94B]
3. Where lots abut existing municipal streets, the cartway of which
is not paved or curbed in accordance with municipal specifications,
the landowner or developer may be required to pave and curb such municipal
street for 1/2 of the width of the cartway. Council may accept other
acceptable security in lieu of the actual required paving and curbing.
Council, acting on the advice of the Engineer, shall decide if such
paving and curbing or security thereof shall be required in these
instances.

b. Duplexes and townhouses, either:
i.
Development not exceeding four buildings and not requiring any
new street for access to the units or lots: 24 feet, or
c. Streets abutting apartments, commercial or industrial lots: as determined
by a study of trip generator or as determined by the Municipal Standards.
4. Street paving. All paving and curbing of streets shall be constructed
strictly in accordance with the details as set forth in the Municipal
Standards. At intersections with state or county roads, details shall
conform to state or county requirements, respectively. All fills shall
be thoroughly compacted in accordance with the Grading Ordinance of
Bethel Park and completely consolidated before any paving is placed
thereon. Shoulders of streets, including driveways, shall not slope
more than three-fourths inch per foot above or below the curbs and
shall be adequately drained. Driveways constructed across sidewalk
areas shall conform to shoulder grades.
5. Grades. No grade of less than 1 1/2% nor more than 12% will
be permitted. Leveling areas at all intersections shall be provided.
No change in grade can be at a greater rate than 1% in 10 feet on
residential streets or 1% in 20 feet on through streets as defined
by the Council.
6. Building lines. A minimum building line to meet the zoning regulations
of the district in which the lot is located will be required on all
lots in a subdivision, said building line to be established from the
required minimum right-of-way (or side line) of all present or proposed
streets, roads or ways and, in addition, shall be so located as to
provide 100 feet clear sight distance measured from center line of
each street in the case of corners. Exceptions to building lines may
be granted where slope conditions warrant. The owner shall illustrate
these conditions as a proposed layout showing the topographical contours
of the property. Corner lots shall, in addition to the above-required
building line, provide a building line parallel to the side street
as required by the zoning regulations.

shall be 500 feet and the maximum length, 1,500 feet.

area or in the Pittsburgh Postal Delivery District shall be filed
by the developer. Street names shall be supplied the municipality

A check for $100 per sign shall accompany the list to cover preparations
and installation by municipality forces.

where topography permits, and shall be connected by radii of at least
25 feet.
10. Lots.
a. Lot lines shall be perpendicular to, parallel to or concentric with
street lines, as the case may be, except where approved by the Council
upon recommendation of the Planning Commission because it is desirable
or expedient. All lots shall be such as to meet the zoning regulations
of the district in which the lot is located. Lots on a curve shall
have sufficient width so as to provide a minimum width at the building
line to meet zoning regulations of the district in which it is located.
No lot shall include any part of the public right-of-way to be dedicated.
b. Flag lots shall not be approved.

The surrounding topography would not allow the connection of
the street to any other streets; or
ii.
Existing development would prohibit the extension.
12. Where a street terminates at the proposed plan line, wherein there
is indication that said street will be extended with future development,
a turnaround as approved by the Municipal Engineer shall be provided.
13. Dead-end streets or cul-de-sac shall not exceed 600 feet in length,
unless the Planning Commission after study of the site, deems it desirable
and so recommends.
14. Monuments and survey points for all major subdivisions. No less than
two permanent monuments for each new street shall be set at such points
as may be designated by the Municipal Engineer. The Municipal Engineer
may require additional monuments based upon topography, length of
street and size of plan. In addition, all corners on the outside perimeter
of the plat shall be marked by smooth steel survey pins one inch in
diameter and three feet long (reinforcing rods are not acceptable.)
If monuments have not been set at the time the final plat is submitted
to Council, there shall be deposited with the Municipal Secretary
a certified check or bond in the amount of $1000 per monument and
$250 per pin. The amount of such check or bond will be returned as
soon as the monuments have been set by the developer in accordance
with this article, and as provided by the Municipal Engineer. If such
work has not been completed within two years after the approval of
the final plat, the Municipal Engineer may cause the monuments to
be set, and pay for the same out of the proceeds of the aforesaid
certified check.
[Amended 5-8-1989 by Ord. No. 5-8-89F]
15. Traffic control signs. Traffic control signs be installed as prescribed
by the Municipal Engineer and Police Department. All costs associated

subdivision, a separate plat covering the remainder of such tract
or parcel of land shall set forth the proposed lots, location of proposed
and existing streets and preliminary plan of drainage, as well as
other pertinent information necessary to safeguard the protection
of property and to provide for the health, safety and general welfare
of the public and community.
1. Sanitary sewers. All sanitary sewers shall be designed in accordance
with the requirements of the Department of Environmental Resources
as to flows, capacities, manholes and supports and cover, but in no
case will a slope of less than 1% be approved. In addition to these
requirements, all service lines and lateral service lines shall be
extended to the property line of the property being served. Required
vents shall be so located that they will not permit the entry of surface
or stormwater into the sanitary sewer. All construction related to
sanitary sewers shall be in conformity with the Municipal Standards.
