Framework / Assessment California Forests and Rangelands: Proposed Indicators Summary Projected new, more fire-resilient development that would replace existing historically high risk WUI. Current WUI that has both high adjacent fire threats, and characteristics that create high susceptibility to fire damage (e.g. vegetation density and structure, ignition-prone building materials, poor design and lower fire protection capacity) can have its risk level reduced by replacing the adjacent wildland fuels with high density Interface. The new Interface would provide both a spatial buffer to wildland fire threats, and would also be less fire-prone, due to current design standards and improved community planning requirements associated with new development.
