Boundaries The boundaries of Philadelphia neighborhoods are often not official or precise. However, Cedarbrook has four precise boundaries that make it almost precisely rectangular. These are: •
Cheltenham Avenue to the northeast (a county line and city limit, beyond which lies
Cheltenham Township,
Montgomery County); • Ivy Hill Road to the northwest (a county line and city limit, beyond which lies
Wyndmoor,
Springfield Township,
Montgomery County); and • Stenton Avenue to the southwest (a non-official intra-Philadelphia boundary, but nevertheless unequivocally dividing Cedarbrook from
East Mount Airy). • Washington Lane to the southeast (beyond which lies
West Oak Lane).
ZIP code The 19150
