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.
[Added 6-12-1978 by Ord. No. 1050]
A. 
Boundary lines shall be perpendicular to, parallel to or radial to street lines, as the case may be, except where otherwise permitted by the City Planning Commission because desirable or expedient.
B. 
Lots shall have a minimum area of 7,200 square feet (not including street dedications) and a minimum width at the building line of 50 feet.
C. 
No lots shall be approved unless public water and public sewers are available or there is an approved agreement by the Pennsylvania Department of Environmental Resources for an interim on-site sewage disposal system. A bond sufficient to guarantee installation may be posted with the city pending availability.
[Amended 11-27-1971 by Ord. No. 919]

On-site sanitary sewage facilities must be certified by the Pennsylvania Department of Environmental Resources.

(a) 
A copy of an agreement approved by the Pennsylvania Department of Environmental Resources prior to the issuance of a permit for an interim on-site sewage disposal system.
(b) 
An approval of the Pennsylvania Department of Environmental Resources of the interim sewage disposal system design for the specific building site.
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.

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.
