1. 
The following land subdivision principles, standards, and requirements shall be applied by the Board of Supervisors of the Township in evaluating plans for proposed subdivisions.
2. 
The standards and requirements outlined herein shall be considered minimum standards and requirements for the promotion of public health, safety, morals and general welfare.
3. 
Where literal compliance with the standards herein specified is clearly impractical, the Board of Supervisors may modify or adjust the standards to permit reasonable utilization of property while securing substantial conformance with the objectives of this chapter.
4. 
Whenever other Township regulations impose more restrictive standards and requirements that those contained herein, such other regulations shall be observed.
[Ord. No. 8/28/1974, 8/28/1974]
1. 
Zoning. Proposed land use shall conform to Chapter 27, the Township Zoning Ordinance, of this Code.
2. 
Hazards. Land subject to hazard to life, health or property shall not be subdivided for residential purposes until such hazards have been eliminated or unless adequate safeguards against such hazards are provided by the subdivision plan.
3. 
Neighborhood Coordination. Proposed subdivision shall be coordinated with existing nearby neighborhoods so that the community, as a whole, may develop harmoniously.
[Ord. No. 8/28/1974, 8/28/1974]
1. 
Township Plans. Proposed streets shall be properly related to such street plans, or parts thereof, as have been officially prepared and adopted by the Township including the Comprehensive Plan (as amended).
2. 
Other Plans. Proposed streets shall further conform to such Township, County and State road and highway plans as have been prepared, adopted and/or filed as prescribed by law.
3. 
Topography. Streets shall be logically related to the topography as specified in § 22-507.
4. 
Residential Service. Residential service streets shall be so laid out as to discourage through traffic, but provisions for street connections into and from adjacent streets will generally be required. Such street systems shall be designed so as to minimize street intersections and pedestrian-vehicular conflict points.
5. 
Resubdivision. If lots resulting from original subdivision are large enough to permit resubdivision or if a portion of the tract is not subdivided, adequate street rights-of-way to permit further subdivision shall be provided as necessary.
6. 
Marginal Access Streets. Where a subdivision abuts, or contains an existing or proposed feeder, connector, or arterial street, the Supervisors may require marginal access streets, rear service alleys, reverse frontage lots or such other treatment as will provide protection for abutting properties, reduction in the number of intersections with the major street, and separation of local and through traffic.
7. 
New Partial Street. New half or partial streets shall not be permitted, except where essential or reasonable subdivision of a tract in conformance with the other requirements and standards of this chapter and where, in addition, satisfactory assurance for dedication of the remaining part of the street can be secured.
8. 
Existing Partial Street. Wherever a tract to be subdivided borders on an existing half or partial street, the other part of the street shall be plotted within such tract.
9. 
Dead-End Streets. Dead-end streets shall be prohibited, except as stubs to permit future street extension into adjoining tracts, or when designed as a cul-de-sac.
10.

Turnaround. Culs-de-sac shall be provided at the closed end with a hard surface turnaround, having a minimum radius to the outer pavement edge, or curbline, of 50 feet.
3. 
Extension. Unless future extension is clearly impractical or undesirable, the turnaround right-of-way shall be placed adjacent to a property line, and a right-of-way of the same width as the street shall be carried to the property line in such a way as to permit future extension of the street into the adjoining tract.
[Ord. No. 8/28/1974, 8/28/1974]
1. 
Street Classification.
A. 
Rural Service Roads. Roads located in substantially rural areas and providing direct access to abutting house or farm properties. Since certain of these roads eventually may become a part of the Township's feeder or residential service street system, sufficient right-of-way is required for this possibility.
B. 
Service Streets. Streets providing direct access to abutting residential properties and ideally carrying no through traffic. These streets are ordinarily part of a subdivision.
C. 
Feeder Roads. Roads designed to collect traffic and feed it to the connector and arterial system and sometimes to connect business and other areas of the community.
D. 
Connector Highways. Traffic ways which provide the principal connections among communities and to the arterial highways system.
E. 
Arterial Highways. Major highways serving large volumes of relatively long distance traffic, and intended primarily for inter-city and commuter traffic at high speeds. It includes both limited access expressways and arterial highways which have access to adjacent properties and intersections at grade.
F. 
Marginal Access Streets. A residential service street parallel and adjacent to feeder, connector, or arterial streets, providing access to abutting properties and control of intersections with the feeder, connector or arterial street.
2. 
Street Widths. Minimum street widths for proposed streets and extensions or continuations as follows:

Standards of PennDOT
3. 
Additional Width. Additional right-of-way and cartway widths may be required by the Board of Supervisors for the following purposes:
A. 
To promote public safety and convenience.
B. 
To provide parking space in commercial districts and in areas of high density residential development.
4. 
Extension of Nonconforming Street. Short extension of existing streets with lesser right-of-way and/or cartway widths than prescribed by this § 22-505 may be permitted; provided, however, that no section of the new right-of-way less than 50 feet in width shall be permitted.
5. 
Width Addition to Nonconforming Street. Where a subdivision abuts or contains an existing street of inadequate right-of-way width, additional right-of-way width in conformance with the above standards is recommended.
6. 
Curbs. Curbs shall be installed along both sides of all streets. The Township Supervisors shall have the option of waiving curbs in areas where the lot frontage exceeds 90 feet. Curbs shall be concrete, of the vertical type or the rolled curb-and-gutter type. The transition from one type of curb to another shall be made only at a street intersection, and adequate provisions shall be made for driveway entrances. Curbs and gutters, if any, are to be constructed on the street right-of-way.
7. 
Sidewalks. Sidewalks may be required on both sides of the street in subdivisions with typical lot width of 90 feet or less at the building setback lines, and where semidetached, row, or multifamily structures are planned. Sidewalks may also be required by the Supervisors on both sides of the street in subdivisions where lots are greater than 90 feet in width if it would be desirable to continue sidewalks that are existing in adjacent subdivisions, or to provide access to community facilities, such as schools, shopping areas and recreation areas. Sidewalks shall be located within the street right-of-way, one foot from the right-of-way line, and shall be a minimum of four feet wide, except along collector and arterial streets, and in the vicinity of shopping centers, schools, recreation areas, and other community facilities, where they shall be a minimum of five feet wide. Generally, a grass planting strip should be provided between curb and sidewalk. Where rolled curb and gutter is used, a grass planting strip shall be provided. Sidewalks shall be constructed as specified by the Board of Supervisors.
