Subdivision of land shall be done in a manner
that will not have the effect of barring adjacent property from access
to the streets and ways of the subdivision.
The City Planning Commission will not approve
a subdivision having any reserve strips surrounding the property or
having any area reserved for any purpose which will make such area
unprofitable for regular or special assessments. (This clause prevents
the developer from recording a plan that has odd-shaped pieces and
remnants of land which cannot be sold or fully utilized for private
use and ultimately becoming a tax delinquent property.) Areas to be
used for playgrounds, parks or planting shall be dedicated for public
use.
When desirable or expedient, adequate easement
or dedications for public service utilities shall be provided for
sanitary and storm sewers, waterlines, electric power and gas lines
and similar services, and no structure or obstruction of any kind
shall be placed or allowed to be placed where it will interfere in
any way with an easement. Easements shall also be provided for surface
water drainage where required.
In general, streets, ways and alleys shall be
laid out so as:
A. To continue any established street, alley or way at
not less than its existing width.
B. To continue any street, alley or way previously located
by ordinance, though not opened, at not less than its width as planned.
C. To have grades of not less than 0.5 of 1% nor more
than 10%, except that grades in excess of 10% may be approved by the
City Planning Commission where it is clear that no traffic hazard
is or will be created thereby.
D. Dead-end streets will be permitted when it is clear
that through traffic at such a street end is not essential to the
street system in that district. A vehicle turning space having a radius
of not less than 40 feet shall be required at the end of any dead-end
street so permitted.
E. In residential districts, the maximum length of a
block shall be no greater than 1,200 feet. In all blocks over 800
feet long, there shall be provided a pedestrian walkway at least 10
feet wide through and near the center of the block. The walkway shall
be paved with a four-foot walk.
Minimum width of streets, ways and alleys shall
be as follows:
A. No street in a subdivision, plot or replot of land
shall have a width of less than 50 feet.
B. When subdivisions, plots or replots abut on state
highways or the aforesaid highways run through the property to be
subdivided, a minimum right-of-way of 60 feet will be required. The
right-of-way of present roads shall be shown with dotted lines and
marked. The area between the present and proposed right-of-way lines
should be marked "Proposed widening."
C. All ways or alleys shall have a width of not less
than 20 feet.
D. The paved width of streets between curbs shall be
not less than 30 feet.

In laying out allotments, the internal street
system of a subdivision shall be so designed as not to encourage its
use by through traffic.
[Amended 12-21-1994 by Ord. No. 1646]
No change in a subdivision or in the plan of
a subdivision already approved can legally be made without the review
of the City Planning Commission and approval of the City Council.
The City Planning Commission may authorize and
approve departures from any of the provisions and requirements set
forth herein when, in the opinion of the City Planning Commission,
such departure is necessary and desirable.

Accompanying the submission of any subdivision
plans to the City Planning Commission, the subdivider shall furnish

all proposed improvements, with endorsed approval by the City Council.
The subdivider shall also furnish evidence, in writing, from the Municipal/Consulting
Engineer that a sufficient cash deposit has been made with the City
of Greensburg for the installation charge imposed by the Municipal
Authority of Westmoreland County for the installation of each fire
hydrant required in the proposed subdivision.
