This website provides a limited number of Substructure Maps in “pdf” format via GIS polygons representing grids containing URL links. Across various areas of Los Angeles County, paper maps were created by Public Works (PW) and its predecessor Departments to show underground utilities such as cable TV, gas, oil, and telephone lines.

Though most of these maps are no longer updated, they can be useful as a research resource. Every reasonable effort has been made to assure the accuracy of this data and the maps referenced. Some cities may provide substructure information for the areas not covered by these grids. Additional and more accurate substructure data and information may also be obtained through the utility companies. Before digging, it is strongly advised to contact the Underground Service Alert (DigAlert Express) at www.digalert.org/digexpress.html or by calling 811.

Designed, created and shared by the Los Angeles County Enterprise GIS (eGIS) team, the Los Angeles County Canvas Basemap is designed using minimal colors, labels and features. City boundaries, roads networks, land types and national hydrographic data are a few of the layers used to create this basemap. Unlike the Los Angeles County Base Basemap, the Canvas does not contain aerial imagery. This basemap covers the extent of Los Angeles County and may be used for large scale mapping. This basemap is cached up to scale 1: 564.

Designed, created and shared by the Los Angeles County Enterprise GIS (eGIS) team, the Los Angeles County Streetmap Basemap has been designed to show the transportation network and jurisdictions across the entire county. Data included in this basemap but not limited to include freeways, highways, major and minor roads, railways, Metro lines, Metro stations, city boundaries, hillshade, national hydrographic data and land types. Designed to be suitable for large scale mapping, the basemap includes building footprints, address point and LMS data. This basemap is cached up to scale 1: 564.

US Postal Service ZIP Code boundaries. This layer was created by Los Angeles County eGIS to align with parcel boundaries.ZIP is an acronym for Zone Improvement Plan.Legal vs. Postal Cities: Many users confuse the name the Post Office delivers mail to (e.g. Van Nuys, Hollywood) as a legal city (in this case Los Angeles), when they are a postal city. The County contains 88 legal cities, and over 400 postal names that are tied to the ZIP Codes. To support usability and geocoding, we have attached the first 3 postal cities to each address, based upon its ZIP Code.The US Postal Service is the authoritative source for ZIP Code data. See their website for more information.

This layer represents current city parcels within the City of Los Angeles. It shares topology with the Landbase parcel lines feature class. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most current geographic information of the public right of way, ownership and land record information. The legal boundaries are determined on the ground by license surveyors in the State of California, and by recorded documents from the Los Angeles County Recorder's office and the City Clerk's office of the City of Los Angeles. Parcel and ownership information are available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.Associated information about the landbase parcels is entered into attributes. Principal attributes include:PIN and PIND: represents the unique auto-generated parcel identifier and key to related features and tables.

In 2014 and 2015, The LA County Enterprise GIS team under the Geographic Information Officer worked with the Unincorporated Area Deputies and Field Deputies of each Board Office to establish names that reflect the desires of residents. CSAs differ from the more informal Community geographies because:They are focused on broad statistics and reporting, not mapping of communities.They represent board approved names assigned to Census block groups and city boundaries.They cover the entire unincorporated County (no gaps).There are not overlapping areas. Additionally, CSAs use the following naming conventions:All names are assumed to begin with Unincorporated (e.g. Unincorporated El Camino Village) which will not be part of the CSA Name (so the name of the Statistical Area would be El Camino Village).Names will not contain “Island.” Beginning each name with Unincorporated will distinguish an area from any surrounding cities. There may be one or more exceptions for certain small areas (e.g. Bandini Islands)A forward slash implies an undetermined boundary between two areas within a statistical geography (e.g. Westfield/Academy Hills or View Park/Windsor Hills)Certain established names may include hyphens (e.g. Florence-Firestone)Aliases may be defined in parentheses (e.g. Unincorporated Long Beach (Bonner/Carson Park))The original set of names were derived from community names used in the 2011 Redistricting process, chosen with the assistance of the Board of Supervisors. Updates: 2025 August: CSA updated for San Gabriel city annexation (effective date 8/6/2025). 2025 April: CSA updated for Long Beach city communities. These community areas and names were reviewed and approved by the City of Long Beach - Community Development Department, Advance Planning Division on 3/26/2025. Contacts: Scott Kinsey Scott.Kinsey@longbeach.gov, Bradley Bounds Bradley.Bounds@longbeach.gov, Alejandro Sanchez-Lopez Alejandro.Sanchez-Lopez@longbeach.gov2025 March: CSA update for Duarte City annexation; and Arcadia City detachment and Monrovia City annexation (effective date 3/17/2025).2024 December: CSA data update to include Whittier City annexation (effective date 11/13/2024).2024 April: CSA data updated to include La Verne City annexation (effective date 4/1/2024).2023 December: CSA data updated to include "Unincorporated Charter Oak" (south of 10 Freeway) into "Unincorporated Covina".2023 June: CSA data was updated to include "Kinneloa Mesa" community, which was a part of Unincorporated East Pasadena.2023 January: Updated layer schema to include feature type (“FEAT_TYPE”) field, which can be one of land, water, breakwater, or pier (consistent with the City Boundaries layer).2022 December: CSA data was updated to incorporate the “Tesoro Del Valle” annexation to the city of Santa Clarita. Unincorporated Valencia is now completely annexed to the City of Santa Clarita. In addition to land area, this data also includes other feature types such as piers, breakwater and water area. 2022 September: CSA data was updated to match with city boundaries along shoreline/coastal area and minor boundary adjusted in some other areas.

This application provides users with access to download PDFs of Community Profiles (for LA County, unincorporated and city areas), as well as maps of LA County Supervisorial Districts in various page sizes and detail. The Supervisorial maps reflect the district boundaries established on December 15, 2021 by the County of Los Angles Citizens Redistricting Commission.These maps were created by the Survey Mapping Property Management team in Public Works, and are meant for informational purposes only.

This is the zoning layer for UNINCORPORATED areas of Los Angeles County. It does not draw at all scales because there are lots of records (so basically for speed and performance), so it is scale dependent. Also, why only for UNINCORPORATED areas? Because there are 88 cities in L.A. County and they each manage their zoning and land use information separately.

For more complete information, see Title 22 (Planning and Zoning) of the Los Angeles County Code, or visit the Department of Regional Planning's website here.

PLEASE NOTE: Santa Catalina Island is not included in this dataset. It is in a separate data layer since Catalina has specific zoning categories that differ from the Countywide zoning categories found in Title 22. The Department of Regional Planning performs all land use planning functions for the UNINCORPORATED areas of Los Angeles County. Our services include long range planning, land development counseling, project/case intake and processing, environmental review and zoning enforcement for each of our County UNINCORPORATED communities.What is an UNINCORPORATED area of Los Angeles County?There are 88 incorporated cities within Los Angeles County, each with its own city council. The areas that are NOT part of these cities are considered to be UNINCORPORATED County territory. More than 65 percent of Los Angeles County is UNINCORPORATED. For the approximately 1 million people living in these areas, the Board of Supervisors and County departments provide the municipal services.LAST UPDATED: 4/9/25 for several zone changes related to the South Bay, West San Gabriel, and Westside Area Plan updates. These updates took effect on 4/10/25.NEED MORE FUNCTIONALITY? If you are looking for more layers or advanced tools and functionality, then try our suite of GIS Web Mapping Applications.

This resource is a member of a series. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System (MTS). The MTS represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads shapefile includes all features within the MTS Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in the MTS that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

The CDP boundary usually is defined by the Census Bureau in cooperation with state, local or tribal officials. The boundaries are updated prior to each decennial census. These boundaries, which usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity boundary, have no legal status, nor do these places have officials elected to serve traditional municipal functions. CDP boundaries may change from one decennial census to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does not necessarily have the same boundary. CDPs must be contained within a single state and may not extend into an incorporated place. There are no population size requirements for CDPs. incorporated CDP data is download from Census Bureau's TIGER 2020 website (https://www2.census.gov/geo/tiger/TIGER2020/PLACE/) and extracted for Los Angeles County. This data includes LA County 88 incorporated cities and 54 CDPs.Data Fields:GEOOID: ID field (combination of State code and place code)STATE: State code (06 for California)PLACE: City and CDP codeNAME: Place name (City and CDP name)LSAD: Type - City or CDPAREA: Area in US Acre.
