City Annexations Feature Layer

This layer contains information for locating past and present legal city boundaries within Los Angeles County. The Los Angeles County Department of Public Works provides the most current shapefiles representing city annexations and city boundaries on the Los Angeles County GIS Data Portal. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California. Numerous records are freely available at the Land Records Information website, hosted by the Department of Public Works. Principal Attributes: NO: The row number in the attribute table of the PDF Annexation Maps. (See Below) ANNEX_No: These values are only used for the City of Los Angeles and Long Beach. NAME: The official annexation name. TYPE: Indicates the legal action. * A - represents an Annexation to that city. * D - represents a Detachment from that city. * V - is used to indicate the annexation was void or withdrawn before an effective date could be declared. * 33 - Some older city annexation maps indicate a city boundary declared 'as of February 8, 1933'. ANNEX_AREA: is the land area annexed or detached, in square miles, per the recorded legal description. TOTAL_AREA: is the cumulative total land area for each city, arranged chronologically. SHADE: is used by some of our cartographers to store the color used on printed maps. INDEXNO: is a matching field used for retrieving documents from our department's document management system. STATE (Secretary of State): Date filed with the Secretary of State. These are not available for earlier annexations and are Null. COUNTY (County Recorder): Date filed with the County Recorder. These are not available for earlier annexations and are Null. EFFECTIVE (Effective Date): The effective date of the annexation or detachment. CITY: The city to which the annexation or detachment took place. URL: This text field contains hyperlinks for viewing city annexation documents. See the ArcGIS Help for using the Hyperlink Tool. FEAT_TYPE: contains the type of feature each polygon represents: * Land - Use this value for your definition query if you want to see only land features on your map. * Pier - This value is used for polygons representing piers along the coastline. One example is the Santa Monica Pier. * Breakwater - This value is used for polygons representing man-made barriers that protect the harbors. * Water - This value is used for polygons representing navigable waters inside the harbors and marinas. * 3NM Buffer - Per the Submerged Lands Act, the seaward boundaries of coastal cities and unincorporated county areas are three nautical miles from the coastline.
