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. <o:p></o:p> A “Yellow” tag indicates that the property has been assessed and deemed safe for limited access, but certain areas are restricted due to safety concerns. Restricted areas may include parts of the property that are structurally compromised (e.g., living room, garage, etc.) and areas with unstable structures.<o:p></o:p> 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 destroyed Included 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, 2025 This dataset comes from two data sources: 1. Los Angeles County Parcel Data. See this link for for information: https://data.lacounty.gov/documents/4d67b154ae614d219c58535659128e71/about 2. Damage Inspection (DINS) Data from CalFire: Eaton: https://data.lacounty.gov/maps/6254ba9f9c4f4b0f886f24c902c8eda3 Palisades: https://data.lacounty.gov/datasets/CALFIRE-Forestry::dins-2025-palisades-public-view/about Process: 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 <null> to 0. Update March 13th 2025 - per LA County Building and Safety and Environmental Programs Division, we have updated the logic to revert back to earlier logic, where DINS damage information was assigned for the most damaged structure on a parcel, regardless of type. This impacted about 680 properties, increasing the damage counts for the total. Update March 4th 2025 - per LA County Building and safety, we have updated the logic. We only assigned DINS damage information when there was a building that was not a "miscellaneous structure." In some cases, the main house had a lower damage assessment than a miscellaneous structure like a garage. We also did not include DINS data for parcels that ONLY had a miscellaneous structure. We also identified parcels where the was a DINS structure, a site address, but no Parcel Unit information. In this case we calculated the number of units on the parcel to be the same as the number of DINS units. This was about 300 parcels. Lastly, we reviewed individual parcels where the parcel was in the middle of a transaction/transition (the parcel AIN had changed) - we reviewed about 25 parcels and manually entered the correct information for the parcel from the Assessor portal.

2025年5月7日更新——BSD_Tag标签已最终敲定,定义如下。<o:p></o:p>"红色标签(Red tag)"表示该物业经评估后因野火造成的严重损毁或安全隐患被认定为不适宜居住,红色标签物业不得进入或占用。<o:p></o:p>"黄色标签(Yellow tag)"表示该物业经评估后可有限进入,但出于安全考虑部分区域受限。受限区域可能包括结构受损的物业区域(例如客厅、车库等)以及结构不稳定的区域。<o:p></o:p>2025年4月28日更新——新增字段TT_Eligible,其包含由Tetratech确定的最终资格状态,Tetratech已对物业开展人工审核。该字段取值如下:Eligible from DINS (n=11806):来自DINS的合格对象(样本量=11806);Excluded by Tetratech (n=242):通常为大型建筑群中的独立公寓,仅少数公寓遭受损毁或破坏;Included by Tetratech (n=79):指DINS数据错误将地块标记为未受损或仅受轻微损毁的物业。<o:p></o:p>2025年4月25日更新——BSD_Tag字段已根据建筑安全部(Building and Safety Department,BSD)的修改与更正内容完成更新。<o:p></o:p>2025年3月28日更新——初步BSD_Tag标签/ATC数据已添加至BSD_Tag字段。源数据来自BSD,并已与地块DINS(Damage Inspection,灾害检查)数据集关联。ATC的可选取值为:黄色(限制使用)与红色(不安全)。原始数据中存在部分绿色(已检查)记录,但由于检查人员仅聚焦于灾情较重的案例,此类记录并不完整。DINS状态为"已损毁(损毁程度>50%)"的住宅与商业地块同时被标记为红色(不安全)。若单个地块存在多条BSD记录,则采用灾情更严重的取值。<o:p></o:p>重要提示:ATC数据仍在审核与完善中,因此BSD_Tag字段的取值可能发生变更。此外,ATC数据仅适用于未合并地区。<o:p></o:p>BSD_Tag的计算流程如下:针对伊顿(Eaton)野火区域:红色标签信息来自EPIC-LA提取数据。针对泳池的红色标签核查工作于2025年1月18日至19日开展,因此此类记录已被排除。我们使用以下标准通过地块DINS数据集构建初始红色标签物业库:使用类型(UseType)为住宅或商业、法定城市(LegalCity)为未合并地区、损毁类别为"已损毁"。随后通过地块编号(AIN)关联,使用EPIC-LA数据集的红色标签信息覆盖BSD_Tag字段。针对帕利塞兹(Palisades)区域:流程更为简单。BSD_Tag数据直接来自EPIC-LA/卡拉巴萨斯办事处(Calabasas Office)的调查结果,并通过AIN与地块DINS数据集关联,无需额外查询或处理。<o:p></o:p>本数据集最后更新于2025年3月26日。<o:p></o:p>本数据集来源于两个数据源:1. 洛杉矶县地块数据。相关信息请参阅以下链接:https://data.lacounty.gov/documents/4d67b154ae614d219c58535659128e71/about;2. 来自加州消防局(CalFire)的灾害检查(Damage Inspection,DINS)数据:伊顿区域:https://data.lacounty.gov/maps/6254ba9f9c4f4b0f886f24c902c8eda3;帕利塞兹区域:https://data.lacounty.gov/datasets/CALFIRE-Forestry::dins-2025-palisades-public-view/about。<o:p></o:p>数据集处理流程:本数据集包含加州消防局(CalFIRE)划定的已确定火灾周边区域内的所有地块,以及所有接受过DINS检查的建筑(包括早期版本中已移除的附属建筑)的地块。若单个地块存在多次DINS检查,则将损毁最严重的建筑信息关联至该地块。<o:p></o:p>2025年3月19日更新——为满足新的报告要求,我们修改了公寓(Condominiums)的使用描述:将以"C"结尾的4位使用代码从"住宅-独栋"更改为"住宅-公寓"。<o:p></o:p>2025年3月19日更新——为全面清理所有废墟,我们对28处被标记为"无法进入"的物业使用灾后航拍影像进行了复核并更新。28处中的26处未受损毁,2处被认定为已损毁。此外,我们还对未开展灾害检查(DINS_Count)但评估部门记录的单元总数(Total_Units)大于0的地块进行了人工检查。此举额外识别出40处受损地块(其中36处已损毁)。部分地块对应覆盖多个地块编号的单栋建筑。在建建筑的单元与建筑面积计数被设为0,此类物业的DINS_Count字段值从<null>更改为0。<o:p></o:p>2025年3月13日更新——根据洛杉矶县建筑安全与环境项目部门的要求,我们更新了逻辑,恢复至早期的逻辑:无论建筑类型如何,均为地块上损毁最严重的建筑分配DINS损毁信息。此举影响了约680处物业,提升了总损毁计数。<o:p></o:p>2025年3月4日更新——根据洛杉矶县建筑安全部门的要求,我们更新了逻辑:仅当存在非"附属建筑"的建筑时,才会分配DINS损毁信息。在部分案例中,主房屋的损毁评估等级低于车库等附属建筑。我们也未将仅包含附属建筑的地块纳入DINS数据。此外,我们识别出部分存在DINS建筑、场地地址但无地块单元信息的地块。在此类情况下,我们将地块的单元数量计算为等于DINS单元的数量,共涉及约300处地块。最后,我们复核了处于交易/过渡状态的单个地块(地块AIN发生变更),共复核约25处地块,并从评估部门门户网站手动录入了该地块的正确信息。
