The outline or footprint of each building is indicated, and the buildings are color coded to show the construction material (pink for brick; yellow for wood; brown for adobe). Numbers inside the lower right corner of each building indicate how many stories the building had, while the numbers outside the building on the street front refer to the street addresses, allowing researchers to correlate these locations with census records and city directories. Individual dwellings are marked with "D" or "Dwg." A legend is given at bottom right.
This image combines three maps published by Sanborne. The edges do not align in some instances due to drawing variances.
