What is Your Address?
When William Penn located his city of Philadelphia between two rivers, the Delaware and the Schuylkill, he reasoned that ships could use either river to discharge or to take on new cargo. He envisioned the City growing inward from the shores of both rivers toward Centre Square and Broad Street. This plan influenced the numbering of the north - south streets on his famous grid.

Much land was pre-sold even before the incorporation of the City of Philadelphia in 1682.
Those buying in the City also received a piece of land in the "Liberties," or suburbs.

In total, twenty-three streets ran north and south covering the area from the Delaware to the Schuylkill. On the Delaware side the north - south streets began at Front Street and progressed westward to 2nd Street, 3rd Street, building in number to 13th Street where the numbering ceased at the border of Centre Square (City Hall). The next north-south street, the widest in Philadelphia, was called Broad Street. It ran up to Centre Square, stopped and picked up again on the other side.
At the Schuylkill banks, a new set of north - south streets was counted in reverse, west to east. A Front Street appeared alongside the Schuylkill River, next came 2nd Street, 3rd Street, etc., the numbers climbing as the streets proceeded east toward Broad Street. At Schuylkill 4th Street, North West Square (later, Logan Square) interrupted the north-south streets. To avoid confusion, an "S" for Schuylkill would appear before each numbered street so S Front Street or S 5th Street indicated numbered streets on the west side of Broad Street. If no "S" appeared, the street was located east of Broad Street.

This peculiar repetitive numbering is mentioned in The Stranger's Guide, published by Edward Parker, Bookseller, 178 High Street, published in 1810 and in To the Citizens of Philadelphia: This new plan of the city of Philadelphia and environs taken from actual survey. Created by John A. Paxton, 1811.
On the higher resolution image here you can see the north-south street numbering. Baldwin Park would be between S 4th and S 5th Streets.
You can also see the planned but never completed canals in dark blue running east-west along the future Callowhill Cut and south along Broad Street.
A problem developed that William Penn had not foreseen. Ships were unable to sail very far up the Schuylkill River. The result was concentrated development at the Delaware River side. Settlement lagged near the Schuylkill River. Country estates and farms were established west of Broad Street all the way to the Schuylkill River. The area surrounding Logan Square remained untouched hardwood forest for much of the l700's. Soon the "S" disappeared and the numbering of east to west took over. S 8th Street became 15th Street.
You can see asymmetrical development of the City with the darker brown on the right (east) of the City representing developed land, and vacant land on the Schuylkill.
