North Valley Stream's name reflects its location north of the Incorporated Village of Valley Stream.
In the 1950s, the Southern State Parkway was widened from four lanes to six through the hamlet. The project required roughly 213 North Valley Stream area homes located along the path to be moved or demolished.
