Top-risk counties, one-pagers for BRIC applications

FEMA Building Resilient Infrastructure and Communities. The FY2026 application window closed 2026-07-23; these one-pagers remain available for FY2027 preparation and for supporting active applications in review. Generated by scripts/build_bric_one_pagers.py against the current Firewatch risk grid. Top 5 corridor counties.

How to use these

Each one-pager links to a printable HTML version (open and print to PDF) and a markdown source for editing. The quantitative figures:corridor-wide percentile, mean risk within 60 km of the county centroid, active fires within 50 miles:are citable directly. The recommended application-category list is a starting point; replace narrative language with locally specific detail before submission.

Methodology. Risk values come from the Firewatch fire-probability model (4 km grid, monthly timestep). The county-level summary takes the maximum cell risk within 60 km of the county centroid and reports its corridor-wide percentile. Active fires use the WFIGS feed refreshed daily by the site’s data pipeline. See /methods for the model card and limitations.

Caveat. The current risk grid clusters at the top end for several corridor counties (the model’s output saturates), so the top-N ranking may be California-heavy. A spatially blocked re-validation is in progress; one-pagers regenerate automatically once it lands.
