These City Annexation polygons are used for city boundary investigation and analysis. The data may also be used for retrieval of land records and general cartographic purposes. The data is based on the Los Angeles County Seamless Cadastral Landbase, which is jointly maintained by the Los Angeles County Assessor and the Los Angeles County Department of Public Works. (This data is mostly complete, save the creation of ocean features as identified in legal descriptions, 05/29/2013.)
