Countywide layer which divides the County of Los Angeles into 11 unique areas for planning purposes of the unincorporated areas. This layer is referred to as 'DRP Planning Areas.'The General Plan provides goals and policies to achieve countywide planning objectives for the unincorporated areas, and serves as the foundation for all community-based plans, such as area plans, community plans, and coastal land use plans. Area plans focus on land use and policy issues that are specific to the Planning Area. Community plans cover smaller geographic areas within the Planning Area, and address neighborhood and/or community-level policy issues. Coastal land use plans are components of local coastal programs, and regulate land use and establish policies to guide development in the coastal zone. Please refer to the Planning Areas Framework chapter in the General Plan here.LAST UPDATED: 4/9/25 for a slight boundary change related to the South Bay, Area Plan update (in the community of Del Aire).

The Federal Emergency Management Agency (FEMA) creates and provides authoritative data related to flood insurance. Using that data, the Los Angeles County Department of Public Works has developed a public-facing web viewer for accessing flood zone information in the County of Los Angeles (Flood Zone Determination Website). Flood Zones are represented by letters for special flood hazard areas by FEMA. For example, Zone A areas have a 1 percent annual chance of flooding. This flood is also called the 100-year flood. Property owners with structures in Flood Zone A, which have a federally backed mortgage are required to obtain flood insurance.

Purpose:

To provide flood zone information to the public.

Supplemental Information:

Data from Flood Insurance Rate Maps (FIRMs), where available digitally, can be found on the official FEMA’s National Flood Hazard Layer. The DFIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper Flood Insurance Rate Maps (FIRMs) FEMA Flood Maps can be obtained from the FEMA Flood Map Service Center (MSC) The National Flood Hazard Layer (NFHL) is a digital database that contains flood hazard mapping data from FEMAs National Flood Insurance Program (NFIP). This map data is derived from Flood Insurance Rate Map (FIRM) databases and Letters of Map Revision (LOMRs). The NFHL is for community officials and members looking to view effective regulatory flood hazard information in a Geographic Information Systems (GIS) application.

FEMA has additional information on the National Flood Insurance Program and Flood Hazard Mapping.

GIS-NET Public was developed to provide the Public with spatial tools and planning and zoning information in the UNINCORPORATED areas of Los Angeles County. It was developed by the Los Angeles County Department of Regional Planning's (DRP) GIS Section. This application replaces a previous application that was in service from January of 2013 to September 2018. The application uses Geocortex Essentials software from Latitude Geographics. Comments about the application can be sent to gis@planning.lacounty.govThe 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 1 million people living in these areas, the Board of Supervisors and County Departments provide the municipal services.

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.

Zoned Districts were established when zoning was initially created for the UNINCORPORTED areas of Los Angeles County. They served to divide the County into smaller distinct units for easier record keeping and organization. Zoned Districts remain in use to identify and track records from the earliest period, and for performing queries regarding permits and ordinances adopted over time. For a list of Zoned Districts or other information regarding these districts, please refer to Title 22 of the Los Angeles County Code here.LAST UPDATED: 3/19/25 for an annexation to the City of Duarte.NEED MORE FUNCTIONALITY?

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.

State law requires sellers of real property to disclose "any fact materially affecting the value and desirability of the property". Assembly Bill 2776, which went into effect January 1, 2004, requires such disclosure when the property is either within two miles of an airport or if it is within an "airport influence area". The disclosure notice must state that the property may be subject to noise, vibration, odors or other annoyances or inconveniences "associated with proximity to airport operations". This law defines the "airport influence area" as the area where airport-related factors "may significantly affect land uses or necessitate restrictions on those uses as determined by an airport land use commission". The California Public Utilities Code establishes airport land use commissions in every county to provide for the orderly development of air transportation and ensure compatible land uses around airports which are open to public use. According to the State Division of Aeronautics, the "airport influence area" is usually the planning area designated by an airport land use commission for each airport.
