12. 
Secondary Means of Access.
A. 
In all residential subdivisions or land developments containing a total of 25 or more dwelling units in the entire plan, at the time that an application for preliminary approval is submitted, the applicant shall provide a secondary means of access to and from the plan. If the applicant or landowner on whose behalf the applicant submits an application owns additional land immediately adjacent to or part of a larger tract from which a subdivision is proposed, the applicant or landowner shall not divide the property into separate subdivision plans of 24 or fewer lots to avoid the requirement to provide a secondary means of access. Regardless of the amount of property included in the subdivision proposed for approval, a preliminary layout of a street system that demonstrates compliance with this subsection shall be required for the entire tract or tracts.
B. 
The secondary means of access shall meet the following standards.
(1) 
The secondary means of access shall be a public street for two-way travel constructed to Borough specifications.
(2) 
The secondary means of access shall be provided by one of the following alternatives:
(a) 
A direct connection shall be made to an existing public street outside the proposed plan that is classified as an arterial or collector street by means of a public street right-of-way.
(b) 
If a direct connection to an existing arterial or collector street is not available, a direct connection shall be made by means of a public street right-of-way to an existing local street outside the proposed plan, provided the existing local street intersects with an arterial or collector street within 2,500 feet of the local street's intersection with the secondary means of access.
(c) 
If a direct connection to an arterial or collector street or a direct connection to an existing local street within 2,500 feet of an arterial or collector street is not available, a direct connection shall be made by means of a public street right-of-way to an existing local street outside the plan. If the primary means of access to the plan is proposed from the same existing local street, the secondary means of access shall be located at least 1,500 feet from the point of intersection of the primary means of access with that existing local street.
(d) 
If a secondary means of access as described in Subparagraph (a), (b) or (c) is not available, a direct connection shall be made by means of a public street right-of-way to a proposed public street in a development that is pending approval or under construction on immediately adjacent property.
(e) 
If a secondary means of access as described in Subparagraph (a), (b), (c) or (d) is not available, a direct connection shall be made by means of a fifty-foot public street right-of-way dedicated to the property line of immediately adjacent undeveloped property for the purpose of extending a future public street into the undeveloped property. In this case, the applicant shall submit a drawing analyzing the feasibility of extending a future public street into the adjacent property at the selected location.
(f) 
If a secondary means of access as described in Subparagraph (a), (b), (c), (d) or (e) is not available, a direct "emergency only" connection shall be made by means of a public street right-of-way to an existing public street to provide access to the plan by emergency vehicles. Use of the "emergency only" access may or may not be restricted to emergency vehicles, subject to approval by Borough Council.
(3) 
In evaluating the alternative proposed by the applicant for providing the secondary means of access, the Planning Commission and Borough Council shall consider whether the alternative proposed is the least disruptive to existing neighborhoods, considering the number of homes affected by the increased traffic, the width and condition of the existing cartway, the availability of off-street parking, the feasibility of on-street parking and any other relevant factors.
(4) 
When the primary means of access connects to an existing public street in an established neighborhood and the secondary means of access is not proposed to be constructed in Phase One of a phased development plan, the construction of the secondary means of access shall be bonded with the public improvements in Phase One. The approved secondary means of access shall be constructed to Borough standards within the entire limits of the right-of-way approved in Phase Two during the construction of Phase Two.
(5) 
When the primary means of access connects to an existing public street in an established neighborhood, the secondary means of access shall be used for all construction vehicles entering and leaving the plan during construction and following completion of the secondary means of access until all subsequent phases of the plan have been completed.
[Ord. 603, 12/30/1991, § 605]

The following standards shall apply to all lots proposed to be subdivided or developed in accordance with this chapter.
A. 
Area. Minimum lot area shall conform to the requirements of the Borough Zoning Ordinance [Chapter 27]. In the case of attached dwelling units, the division of existing structures along common walls may be approved even if the lot area for each dwelling unit does not meet the minimum requirements of the Zoning District, provided the building in which the dwelling units are located met the minimum lot area requirements of the Zoning Ordinance at the time of approval for construction and the number of lots created out of the original approved lot is no greater than the number of dwelling units in the building constructed on that lot.
B. 
Frontage. All lots created by a subdivision shall have frontage along the right-of-way of a public street and the width of the frontage shall conform to the requirements of the Borough Zoning Ordinance [Chapter 27].
C. 
Subdivisions Along Common Walls. In the case of single-family attached, two-family, triplex, fourplex or townhouse dwelling units, the dwelling units may be subdivided along common walls for the purpose of conveying the units in fee simple after construction even though the resulting lots are less than the minimum lot area or lot width required by the Borough Zoning Ordinance [Chapter 27], provided the original lot containing the attached dwelling units meets the lot width and lot area required for the dwelling type at the time of construction, there is no increase in dwelling unit density and there is no further subdivision of any common open space approved in the original plan.
D. 
Double Frontage. Double frontage lots, other than corner lots, shall be avoided; however, where a double frontage lot is the only practical alternative, vehicular access shall be limited to only one street and that street shall be the street with the lower volume of traffic, if physically feasible. The final plat shall contain a notation restricting vehicular access to one frontage.
E. 
Side Lines. Whenever practicable, the side lines of a lot shall be at right angles or radial to the right-of-way lines of streets.

G. 
Grading. Lots shall be graded to provide drainage away from buildings and, where practical, water shall be drained to the street rather than to adjoining property. The developer shall be required to provide drains or other drainage facilities, as approved by the Borough Engineer, to drain off surface water within the development.
H. 
Driveways.
(1) 
Driveways serving single family and two family dwellings are not required to be paved; however, in lieu of paving, the driveway shall have a covering of slag at least two inches thick for a distance of 30 feet from the right-of-way of the street. All other driveways shall be paved in accordance with the Borough construction standards and/or the Pennsylvania Department of Transportation Design Manual, Part 2, Chapter 18.
(2) 
No driveway shall have a slope of more than 15%. Driveways may extend from the right-of-way line of the street to the cartway of the street, but shall not change the grade or contour of the street right-of-way, nor shall any person cut into, fill, or in any way alter any gutter, curbing, drainage ditch or storm sewer, within the right-of-way of a street or easement for the purpose of extending a driveway; or for any other purpose without first obtaining a permit therefor from the Borough Building Inspector.
I. 
Accessibility. Every lot shall be accessible to emergency and public safety vehicles.
J. 
House Numbers. House numbers shall be assigned by the Borough Building Inspector and must be posted at each house so as to be easily visible and readable from the street.
