1. 
General standards. The arrangement, character, extent, width, grade and location of all streets shall conform to the transportation plan in the Comprehensive Plan and shall be considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and shall be appropriate to the proposed uses of the land to be served by such streets. Where not shown on the Official Map or Township Comprehensive Plan, the arrangement and other design standards of streets shall conform to the provisions found herein.
A. 
The arrangement of streets in new subdivisions shall make provision for the continuation of existing streets in adjoining areas. Intersections having opposing streets shall be in alignment with each other unless the Board of Supervisors, in its discretion, determines that conditions do not permit such alignment, in which event offset street intersections shall have a minimum distance between opposing center lines of 125 feet.
B. 
Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall make provision for the proper projection of streets to the boundaries of the tract to be subdivided.
C. 
All lands subdivided and/or all lots developed which are to be the site of 10 or more dwelling units shall provide for at least two street connections to existing public streets. Where the land to be subdivided and/or developed adjoins two or more public streets, the two street connections required by this section shall be made so that not more than one connection is made to each of the adjoining public streets.
D. 
Names of streets shall not duplicate or approximate existing or platted streets names or approximate such names by the use of suffices such as "lane," "way," "court," or "avenue." In approving the names of streets, cognizance may be given to existing or platted names within the postal delivery district served by the local post office. New streets shall bear the same name or number of any continuation or alignment with an existing or platted street.
E. 
Any new street which is proposed to connect to an existing public street shall connect to a street with the lowest classification.
2. 
Intersection design.

Intersections having opposing streets not in alignment with each other shall have a minimum distance of 125 feet between the opposing center lines.
3. 
Cul-de-sac or dead end street design.
[Amended by Ord. No. 1-2022, 7/12/2022]

A maximum of 10% of total street length in any proposed subdivision may be cul-de-sac streets.
C. 
Cul-de-sac streets shall be at least 250 feet in length, shall not exceed 600 feet in length, and shall not serve more than 10 residential dwelling units.
D. 
No more than 25% of the outer edge of paving of the circular portion of a cul-de-sac shall include driveway entrances.
E. 
A snow storage easement shall be established at the end of the cul-de-sac, which shall provide for proper drainage as the snow melts. The easement shall be located so that a snowplow can push snow relatively straight from the street to the far end of the cul-de-sac. This snow storage easement shall be located clear of any driveways or other obstructions and shall have a minimum width of 15 feet and length of 30 feet. There shall be a mountable or ramp-type curb at the approach to the snow storage easement. The easement area shall be provided with an approved type of permeable paving grid reinforcement to prevent plow vehicles from becoming stuck.
F. 
Temporary cul-de-sacs or dead-end streets will not be permitted unless approved by the Board of Supervisors. Any temporary dead-end street shall include a temporary cul-de-sac. An applicant shall provide sufficient documentation indicating that such cul-de-sac is temporary and that the conditions requiring it are to be corrected within the period of time set forth in the approved plan documents. If the approved plan documents do not specify a time for correction, that time shall not exceed three years, unless otherwise approved by the Board of Supervisors. Any street presented by an applicant to have a temporary cul-de-sac shall meet the design requirements of a collector street set forth at § 22-504, Subsection 2D of the Township of South Hanover Code of Ordinances.
G. 
Cul-de-sacs and/or dead-end streets that are extensions of or attached to other cul-de-sacs and/or dead-end streets are prohibited.
H. 
The connectivity index for a proposed subdivision shall be calculated using the EPA Methodology as described in PennDOT Publication 731. The EPA Methodology is calculated by dividing the number of intersections by the sum of intersections and cul-de-sacs. An index of 0.85 or higher is required.
