Repairing disaster damage to public roads and bridges your agency is legally responsible for is eligible. Federal-aid routes are not, because the Federal Highway Administration covers them, even when its Emergency Relief program isn’t activated or doesn’t pay.
Maintenance records or invoices and activity logs, photos, and damage measurements for each site.
Check each road’s functional classification first. Damage on a federal-aid route is never a PA project, so don’t spend time scoping it.
