 This street pattern has remained virtually unaltered to this day.The development of American commercial areas in San Jose extended into this newly surveyed area, just east of the original pueblo site of 1797 (relocated from the 1777 site after major flooding).In the 1870s and mid-1880s, the heart of downtown commercial activity had moved northward along Market Street (immediately west of First Street and part of the Pueblo) to the Santa Clara Street intersection.
