The survey is designed to help future planners make informed decisions about proposed land use changes.
It will make sure decision makers consider structures such as The Onion, which is the domed North Hills home of the Sepulveda Unitarian Universalist Society. A number of other historic structures will be catalogued, including the Forsythe Building in Boyle Heights dating back to the 1880s.
Since December, pilot surveys have been under way in the San Fernando Valley, along portions of Pico Boulevard and Vermont Avenue, and in Boyle Heights.
Many cities have spent years creating data banks about the history of their buildings. L.A. hasn't undertaken a systematic survey until now.
