Equity_EJ/Climate_Hazards (FeatureServer)

View In: ArcGIS JavaScript   ArcGIS Online Map Viewer

Service Description:

This dataset includes the data used to develop Map 10 for the Connect SoCal 2024 Equity Analysis Technical Report, adopted on April 4, 2024. The dataset includes binary indicators for seven climate hazard geographies in the SCAG region based on the latest available geographic information. The nine layers were overlaid using the ArcGIS union tool with a minimum of one and a maximum of six overlapping layers in the region. The climate hazard layers include: flooding, landslides, sea-level rise, extreme heat, wildfires, drought, and earthquake hazard zones. This dataset was prepared to share more information from the maps in Connect SoCal 2024 Equity Analysis Technical Report. To reduce the loading time for the complex geometry of this layer, the vertices were simplified with a tolerance of 1 foot. For more details on the methodology, please see the methodology section(s) of the Equity Analysis Technical Report: https://scag.ca.gov/sites/main/files/file-attachments/23-2987-tr-equity-analysis-final-040424.pdf?1712261887 For more details about SCAG's models, or to request model data, please see SCAG's website: https://scag.ca.gov/data-services-requests
