This dataset seeks to encapsulate right of way parcel information for the Los Angeles County Flood Control District(LACFCD). It contains polygons representing each parcel and attribute information information that lists the basic identification information of those parcels. There is also information on the underlying right-of-way map the parcel polygon and attributes are based on with a link to that map in the Land Records Information Website.This data is maintained by the Right of Way Section of the Survey/Mapping and Property Management Division of the Department of Public Works. It is drawn to be coincident with the county's landbase linework and thus may not be a true representation of a parcel's boundary. It is intended to be used as a general information tool and is emphatically not survey quality.Field ListFacilityThe primary name of the facility this parcel belongs to. Typically the name of the river, stream, or drainage project it is a part of.Parcel_NoThe identification number for a particular parcel within a facility. The parcel number is not necessarilly unique.EstateThe type of estate that the LACFCD holds over a particular parcel. This field will list the following attributes:Fee: The LACFCD owns the parcel outright.Easement: The LACFCD holds an easement over this parcel. The type of easement is not listed in this data. It can usually be found in the linked right of way map or by contacting Right of Way Engineering.Quitclaim: This is a parcel which the LACFCD owned or had an easement over at some point but has now sold, released its claim, or transferred its right of way to another party.Other: This is a catch-all attribute for any sort of relationship that does not fit in the other estate types. One example of this is a permit that grants temporary rights to the LACFCD. Map_NoThe primary right of way map that shows a parcel and that served as the basis for the information shown in the dataset. These maps are maintained and are considered to take precedence over the data in this dataset.MapLinkThis is a link to a a scan of the map, if one exists, listed in the "Map_No" field.

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Though most of these maps are no longer updated, they can be useful as a research resource.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.

As you zoom further into Los Angeles County the aerial imagery layer is displayed at around the scale of 1:18,056. The basemap covers the extent of Los Angeles County, and has been designed to show different levels of detail based on zoom levels. This basemap is cached up to scale 1: 564.

This parcels polygons feature class 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. This field is related to the LA_LEGAL, LA_APN and LA_HSE_NBR tables. PIN contains spaces and PIND replaces those spaces with a dash (-).LA_LEGAL - Table attributes containing legal description. Principal attributes include the following:TRACT: The subdivision tract number as recorded by the County of Los AngelesMAP_REF: Identifies the subdivision map book reference as recorded by the County of Los Angeles.LOT: The subdivision lot number as recorded by the County of Los Angeles.ENG_DIST: The four engineering Districts (W=Westla, C=Central, V= Valley and H=Harbor).CNCL_DIST: Council Districts 1-15 of the City of Los Angeles. OUTLA means parcel is outside the City.LA_APN- Table attributes containing County of Los Angeles Assessors information. Principal attributes include the following:BPP: The Book, Page and Parcel from the Los Angeles County Assessors office. SITUS*: Address for the property.LA_HSE_NBR - Table attributes containing housenumber information. Principal attributes include the following:HSE_ID: Unique id of each housenumber record.HSE_NBR: housenumber numerical valueSTR_*: Official housenumber addressFor a complete list of attribute values, please refer to Landbase_parcel_polygons_data_dictionary.Landbase parcels polygons data layer was created in geographical information systems (GIS) software to display the location of the right of way. The parcels polygons layer delineates the right of way from Landbase parcels lots. The parcels polygons layer is a feature class in the LACityLandbaseData.gdb Geodatabase dataset. The layer consists of spatial data as a polygon feature class and attribute data for the features. The area inside a polygon feature is a parcel lot. The area outside of the parcel polygon feature is the right of way. Several polygon features are adjacent, sharing one line between two polygons. For each parcel, there is a unique identifier in the PIND and PIN fields. The only difference is PIND has a dash and PIN does not. The types of edits include new subdivisions and lot cuts. Associated legal information about the landbase parcels lots is entered into attributes. The landbase parcels layer is vital to other City of LA Departments, by supporting property and land record operations and identifying legal information for City of Los Angeles. The landbase parcels polygons are inherited from a database originally created by the City's Survey and Mapping Division. Parcel information should only be added to the Landbase Parcels layer if documentation exists, such as a Deed or a Plan approved by the City Council. When seeking the definitive description of real property, consult the recorded Deed or Plan.List of Fields:ID: A unique numeric identifier of the polygon. The ID value is the last part of the PIN field value.ASSETID: User-defined feature autonumber.MAPSHEET: The alpha-numeric mapsheet number, which refers to a valid B-map or A-map number on the Cadastral grid index map. Values: • B, A, -5A - Any of these alpha-numeric combinations are used, whereas the underlined spaces are the numbers. An A-map is the smallest grid in the index map and is used when there is a large amount of spatial information in the map display. There are more parcel lines and annotation than can fit in the B-map, and thus, an A-map is used. There are 4 A-maps in a B-map. In areas where parcel lines and annotation can fit comfortably in an index map, a B-map is used. The B-maps are at a scale of 100 feet, and A-maps are at a scale of 50 feet.OBJECTID: Internal feature number.BPPMAP_REFTRACTBLOCKMODLOTARBCNCL_DIST: LA City Council District. Values: • (numbers 1-15) - Current City Council Member for that District can be found on the mapping website http://navigatela.lacity.org/navigatela, click Council Districts layer name, under Boundaries layer group.SHAPE: Feature geometry.BOOKPAGEPARCELPIND: The value is a combination of MAPSHEET and ID fields, creating a unique value for each parcel. The D in the field name PIND, means "dash", and there is a dash between the MAPSHEET and ID field values. This is a key attribute of the LANDBASE data layer. This field is related to the APN and HSE_NBR tables.ENG_DIST: LA City Engineering District. The boundaries are displayed in the Engineering Districts index map. Values: • H - Harbor Engineering District. • C - Central Engineering District. • V - Valley Engineering District. • W - West LA Engineering District.PIN: The value is a combination of MAPSHEET and ID fields, creating a unique value for each parcel.

Los Angeles County Department of Public Works’ Vertical Control Network is composed of more than 1,700 miles (2,720 kilometers) of level runs and comprise nearly 9,000 benchmarks. The basic accuracy of the net is reflected by an indicated field probable error of ± 0.017 feet per mile (4 mm per kilometer) of leveling as determined from conditions of closure. However, because of varying degrees of subsidence and heaving, the true datum is recovered only by obtaining substantial agreement of a number of benchmarks.For each active benchmark, a point representation was created in GIS by locating them based on their description. Parcel data, mile markers, the County Address Management System (CAMS), LARIAC aerials, oblique photos, 2-foot contour lines and/or Google Street View were used in assisting with the location.The creation of the benchmarks in GIS greatly enhances the Vertical Control Network by adding visual context with respect to their representative geospatial locations. With a glance, geospatial patterns can be observed and out-of-place benchmarks can be quickly identified and remapped to the correct location after verification.To facilitate the adjustment, indexing and distribution of adjusted values in the network, the county territory was divided into 33 quads or areas. For identification purposes, each quad was given a name (for example, “Rosemead”, “La Mirada”, “Santa Fe”, and etc.). Index maps, county maps, and other information can be accessed and downloaded on the basis of each of the quads by going to Survey Division’s Benchmark Retrieval System (https://pw.lacounty.gov/sur/benchmark). General adjustments are carried out every 5 to 10 years and the provided elevation data is expected to remain sound during this period. When a quad is adjusted, new elevations will be published and the date of the readjustment will be noted. No historical data is provided, but it can be acquired from Survey Division’s Public Records Counter or via the fee based Optional Technical Research (OTR) program.

The Los Angeles County Flood Control District (District) was established in 1915 and encompasses approximately 2,758 square miles. The District operates and maintains one of the most complex systems of flood control and water conservation in the Country. The District’s current infrastructure includes 14 major dams and reservoirs, 483 miles of concrete and soft-bottom channels, 3,380 miles of underground storm drain conduits, 82,275 catch basins, 48 pump stations, 173 debris basins, 181 crib dams, 29 sediment placement sites, 27 spreading grounds, 21 low-flow diversion structures, 3 seawater barrier systems with 290 seawater barrier injection wells, 1 constructed wetland, and 1 mitigation bank area. Employees of the Los Angeles County Public Works (PW) serve as staff for the District. The District is separate from PW and funds of each entity remain in separate accounts. PW pays the District for the use of District equipment, materials and property used for County purposes. The District is empowered to carry out the objectives of the Los Angeles County Flood Control Act of 1915, California Water Code, Appendix, Chapter 28 (the Act). The objectives are to provide for the control and conservation of flood, storm and other wastewater and to protect from damage such as flood or storm waters, the harbors, waterways, public highways and property within the District. These powers are exercised by the County Board of Supervisors (Board), which acts as the governing body of the District. The duties of the Board include approving the District’s budget, determining the District’s tax rates, approving contracts, and determining when to issue bonds authorized by the voters of the District.

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.

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: 3/19/25 for an annexation to the City of Duarte.NEED MORE FUNCTIONALITY?
