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Though most of these maps are no longer updated, they can be useful as a research resource.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

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.

Update May 7th, 2025 - BSD_Tag is finalized, with definitions below.A “Red” tag indicates that the property has been assessed and deemed uninhabitable due to severe damage or safety hazards resulting from the wildfire. The red tagged properties shall not be entered or occupied.

Update April 28, 2025 - Added.a new field, TT_Eligible, which contains final eligibility status as determined by Tetratech, who performed a manual review of properties. The field has the following values:Eligible from DINS (n=11.806)Excluded by Tetratech (n=242) - generally individual condominiums in a large group where only a few condos were damaged or destroyedIncluded by Tetratech (n=79) - properties where the DINS data incorrectly identified parcels as undamaged or minor damage.Update April 25, 2025 - BSD_Tag field updated with changes and corrections from BSD.Update March 28th 2025 - Preliminary BSD tagging / ATC data added under BSD_Tag field. The source data comes from BSD and was joined to the Parcel DINS dataset. Possible ATC values are Yellow (Restricted Use) and Red (Unsafe). There were some Green (Inspected) records in the original data, however, those are incomplete since inspectors were focused on the more severe cases. Residential and commercial parcels with a DINS status of Destroyed (Damage > 50%) were also given a value of Red (Unsafe). In cases where there was more than one BSD record on a parcel, the more severe value was used. IMPORTANT: The ATC data is still being reviewed and refined. Therefore, the values in the BSD_Tag field are subject to change. Additionally, the ATC data is only available for the unincorporated areas.Process used to calculate BSD_Tag:For Eaton: Red-tagging information came from EPIC-LA extract. Red-tagging with a focus on pools occurred on 1/18-1/19/2025 so these records were excluded. An initial base of red-tagged properties was created with the Parcel DINS data using the following criteria UseType = Residential or Commercial, LegalCity = Unincorporated, and Damage category = Destroyed. The BSD_Tag was then overwritten with the red-tagging coming from the EPIC-LA dataset, joining by AIN.For Palisades: The process was simpler. The BSD_Tag data came directly from EPIC-LA/Calabasas Office survey and joined to the Parcel DINS dataset using the AIN. No additional querying or work was necessary.Dataset last updated on March 26th, 2025This dataset comes from two data sources:1. Los Angeles County Parcel Data. See this link for for information: https://data.lacounty.gov/documents/4d67b154ae614d219c58535659128e71/about2.

If more than one DINS inspection occurred on a parcel, the information from the most damaged building was attached to the parcel. Update March 19th 2025 - To support new reporting requirements, we changed the use description for Condominiums (4-digit Use Code ending in 'C' from Residential - Single to Residential - Condominium'Update March 19th 2025 - To support the complete removal of all debris, all properties that were identified as "Inaccessible" (28 total) were reviewed using post-fire aerial imagery and updated. 26 out of the 28 were undamaged, and 2 were identified as destroyed.Additionally, parcels where a Damage Inspection (DINS_Count) had not been done, but the Assessor had a unit count (Total_Units) greater than 0 were also manually inspected. This resulted in an additional 40 parcels identified as damaged (36 destroyed). Some of these parcels reflect a single building covering more than one property. Buildings that were under construction had their unit and square footage count set to zero. The DINS_Count for these properties was changed from

This map page grid was designed and implemented by the Los Angeles County Fire Department, Information Management Division, and Geographic Information Systems Section. Wholly based on the United States National Grid (USNG), it aims to be the Los Angeles County regional grid because of its ease of use and extensive coverage.

Each block measures 2,000 meters by 2,000 meters and are comprised of four 1,000 meter/1 kilometer USNG blocks. i.e. 11SLT4771, 11SLT4871, 11SLT4770 and 11SLT4870; left to right and up to down. For ease of use each 2,000 meter block is designated by a page number from 1 to 9,750, and it is inferred that the 1,000 meter divisions of each page are designated A, B, C or D; left to right and up to down. Therefore, each 1,000 meter block within this regional grid has a unique descriptor of 4 numerals and 1 letter.

The region covered by the grid includes Los Angeles County completely and 2 of the islands in the Channel Islands archipelago that fall into the Los Angeles County jurisdiction. It also covers close to 100% of Orange County, 50% of Ventura County, and the Los Angeles County adjacent portions of Kern County, San Bernardino County and Riverside County, and a portion of Marine Corps Base Camp Pendleton in Northwest San Diego County.

This web map depicts urban habitat quality of vegetation (landscapes, water features, open space) in the City of Los Angeles.The urban habitat quality raster layer was created by combining CALVEG data with other relevant layers into this master raster. It was then scored in a Max field according to rules for classifying the habitat quality of vegetation that are outlined in Isaac Brown's research on "Managing Cities as Urban Ecosystems". Brown's "research integrates high-resolution land cover and vegetation datasets, and connectivity modeling tools, to estimate and map habitat quality across the City and surrounding areas at a 10-foot (3-meter) spatial resolution. Connectivity of habitat areas is then modeled using Omniscape at a 30-foot resolution for the Elysian Valley sub-area as a proof of concept for the broader City. The result is a quantitative, spatial, “wall-to-wall” valuation of urban landcover as habitat for native biodiversity to live and move, ranging from the most natural to the most urban locations." See Isaac Brown's 2019 UCLA Doctoral Dissertation for more information. Based on UVT LARIAC (2016 Canopy Assessment per above) landcover raster
