(5) 
Where, in the opinion of the Borough Planning Commission, it is desirable to provide for street access to adjoining property, streets shall be extended by dedication to the boundary of such property. Distances between access points to adjoining property shall be based on block length standards set forth in § 215-22B.
(6) 
Where a subdivision abuts an existing street of improper width or alignment, the Borough Planning Commission may require the dedication of land sufficient to widen the street or correct the alignment.
(7) 
Where a subdivision abuts or contains an existing or proposed arterial traffic street, the Borough Planning Commission may require marginal access streets, reverse frontage lots, or other such treatment as will provide protection for abutting properties, reduction in the number of intersections with the arterial street, and separation of local and through traffic. Where a subdivision borders on or contains a limited-access highway or a railroad right-of-way, the Borough Planning Commission may require a street approximately parallel to and on each side of such right-of-way at a distance suitable for appropriate use of the intervening land, as for park purposes in residential districts, or for commercial or industrial purposes in appropriate districts. Such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
