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Though most of these maps are no longer updated, they can be useful as a research resource.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

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. Damage Inspection (DINS) Data from CalFire:Eaton: https://data.lacounty.gov/maps/6254ba9f9c4f4b0f886f24c902c8eda3Palisades: https://data.lacounty.gov/datasets/CALFIRE-Forestry::dins-2025-palisades-public-view/aboutProcess:The dataset includes all parcels within the Established Fire Perimeters from CalFIRE and all parcels that had DINS inspections for any and all structures (including miscellaneous structures which had been removed in earlier version). 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
