§ 395-30. Cul-de-sac streets.

A. 

In the event that the Borough Council shall determine that development on an adjoining property will not occur or deems it unlikely due to the physical and environmental constraints of the tract, the Council may permit a cul-de-sac to be constructed. In the case of streets which are planned for future extension into adjoining tracts and will not be the primary means of access to any lot or dwelling unit, a turnaround is not required.

B. 

Except as provided in Subsection A of this section, any street dead-ended for access to an adjoining property or because of authorized stage development shall be provided with a turnaround within the subdivision or land development and the use of such turnaround shall be guaranteed to the public until such time as the street is extended. If a cul-de-sac turnaround is offset, it shall not be offset to the right. Should a temporary cul-de-sac be proposed, arrangements satisfactory to the Borough Council and Borough Solicitor shall be made for construction and installation responsibilities of all improvements when the temporary cul-de-sac is abandoned and the street is extended.

C. 

Cul-de-sac streets shall be at least 250 feet from the right-of-way of the street intersected to the end of the turnaround. Cul-de-sac streets shall not exceed 500 feet in length as defined in this chapter and shall not furnish access to more than 20 dwelling units. The Borough Council may permit temporary culs-de-sac longer than 500 feet at its discretion if future extension of the cul-de-sac is likely in the opinion of the Council. At its discretion, the Council may permit culs-de-sac to serve more than 20 dwelling units when it believes adequate provision will be made for vehicular circulation and parking.

D. 

Unless future extension is clearly impractical or undesirable, the turnaround right-of-way shall be placed adjacent to the tract boundary with sufficient additional right-of-way width provided along the boundary line to permit extension of the street at full width.

E. 

All cul-de-sac streets, whether permanently or temporarily designed as such, shall be provided at the closed end with a fully paved turnaround. Minimum radius to the pavement edge or curbline shall be 50 feet, and minimum radius to the right-of-way line shall be 60 feet.

F. 

Drainage of cul-de-sac streets shall preferably be toward the open end. If drainage is toward the closed end, water shall be conducted away in an underground storm sewer or by other means approved by the Borough Council.

G. 

The center line grade on a cul-de-sac street shall not exceed 10% and the grade and cross-slope of the turnaround shall not exceed 5%.
