 Survey LA, the result of a 10-year partnership between the City of Los Angeles and the Getty, documents more than 30,000 historic resources, including residential and commercial districts, industrial complexes, bridges, streetlights, and public art. The project resulted in several technological innovations, including a custom GIS-based mobile survey application that allows surveyors to quickly record sites of interest. A citywide historic context statement, and Historic Places LA, a publicly available online inventory of historic resources. Survey LA also took a unique approach to public engagement, producing materials in multiple languages and enlisting hundreds of volunteers to engage an inclusive set of LA's residents in identifying places of social and cultural importance. Most significantly, Survey LA is a proactive tool for incorporating historic fabric into city planning. It broadens the meaning and influence of preservation and serves as a model for preservation nationwide.
