History of our Sewickley Valley

The Sewickley Valley occupies six miles of broad bottomland and heights in Allegheny County, twelve miles downriver from Pittsburgh on the north bank of the Ohio River, bordered by Kilbuck Run on the east and Big Sewickley Creek on the west.

The Sewickley Valley originally lay within Pine Township, created in 1796 out of Pitt Township, which included the land west of the Allegheny River and north of the Ohio, as far as Lake Erie. Ohio Township was cut out of a portion of Pine Township in 1803, and a portion of Ohio Township was designated as Sewickley Borough in 1853; Sewickley Township was taken from Ohio Township in 1854. Today the Sewickley Valley comprises the eleven municipalities of the Quaker Valley School District, listed here in order of date of incorporation: Sewickley (1853), Leet Township (1869), Aleppo Township (1876, became a first class township in 1960), Glen Osborne (1883), Glenfield (1883), Haysville (1902), Leetsdale (1904), Edgeworth (1904), Sewickley Heights (1935), Sewickley Hills (1958) and Bell Acres (1960).
