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) Database (MTDB). The MTDB 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 MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB 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 community standards districts are established as supplemental districts to provide a means of implementing special development standards contained in adopted neighborhood, community, area, specific and local coastal plans within the UNINCORPORATED areas of Los Angeles County, or to provide a means of addressing special problems which are unique to certain geographic areas within the unincorporated areas of Los Angeles County. For detailed development standards for each CSD, please refer to the Community Standards District portion of the Los Angeles County Code (click here).LAST UPDATED: 4/9/25 for several changes related to the West San Gabriel, and Westside Area Plan updates. These updates took effect on 4/10/25.NOTE - A decision was made at the Board of Supervisor's Hearing that the CSD and Setback updates not be included. However, the GIS layers were updated with these changes and were showing on GIS-NET and Open Data between 4/9/25 and 4/14/25. On 4/14/25, these un-adopted changes were removed and the correct data now shows.NEED MORE FUNCTIONALITY?

This line feature layer contains Legal City boundaries within Los Angeles County.

The principal attribute is BDRY_TYPE which represents the boundary feature types. Use its values below for definition queries and layer symbology for your mapping needs.

Coast - This value represents the coastline. This data is carefully maintained by DPW staff, based Los Angeles Region Imagery Acquisition Consortium data.

Land City - This value represents city boundaries on land.

Land County - This value represents the county boundary on land.

Pier - One example is the Santa Monica Pier. Man-made features may be regarded as extensions of the coastline.

Breakwater - Examples include the breakwater barriers that protect the Los Angeles Harbor.

Water - This value is used to separate features representing internal navigable waters and the ocean. Examples of internal waters are found in the Long Beach Harbor and in Marina del Rey.

Ocean - This value is used to represent ocean boundaries between cities in addition to the seaward boundaries of coastal cities. Per the Submerged Lands Act, the seaward boundaries of coastal cities and unincorporated county areas are three nautical miles (a nautical mile is 1852 meters) from the coastline.

This dataset is the primary transportation layer output from the CAMS application and database. This file is a street centerline network in development by Los Angeles County to move toward a public domain street centerline and addess file. This dataset can be used for two purposes:Geocoding addresses in LA County – this file currently geocodes > 99.5% of the addresses in our test files (5,000 out of 8 million addresses) using the County’s geocoding engines.This last statement is important – the County splits the street names and addresses differently than most geocoders. This means that you cannot just use this dataset with the standard ESRI geocoding (US Streets) engine.

• Los Angeles County, CA Non-Hispanic Population Breakdown by Race
• Los Angeles County, CA Hispanic or Latino Population Distribution by Their Ancestries

Good to know

Margin of Error

Data in the dataset are based on the estimates and are subject to sampling variability and thus a margin of error. Neilsberg Research recommends using caution when presening these estimates in your research.

This layer presents the census block groups of the United States in the 50 states, the District of Columbia, and Puerto Rico. It provides detailed boundaries that are consistent with the tract, county, and state data sets and are effective at regional and state levels. This layer can be used for visualization and spatial analysis.

This dataset only contains the projects marked for display on the public internet. Integrating GIS feature classes with flat table data from other databases is a common goal. Previously, this was done using spatial views and DB links; however, the draw and query performance suffered. To work around performance bottlenecks, an ETL (extract-transform-load) process was chosen so that a single feature class is created. It means that the data is no longer live.Users involved in a project typically request SMP for geometry at the following link (replace PROJECT_ID with the appropriate alphanumeric string): https://apps.intranet/prjmgt/piw3/location.aspx?project_id=PROJECT_ID
