The Association of Commerce News Bulletin is a good source for construction announcements dating from 1919-1972. Issues regularly feature a "New Orleans Is Growing" column that itemizes business developments and urban planning initiatives.
In September 1937, the bulletin highlighted the razing of the city's Chinatown:
"Tulane-Crescent Parking Company will start demolition of the old Chinatown area, Tulane Avenue between Rampart and Elk Place, September 15. The area will be converted into a parking lot by October 15."
The same issue nodded to Charles B. Walgreen's intent to demolish the Canal Street Beer Building in order to build a $2,000,000 drug store.
