Council hazard maps, by region
A council map is used only when its licence allows it in a paid report, and each layer is checked by hand. Where a region has none here, the report says the hazard isn’t checked yet and points to the council and the LIM. A hazard that isn’t checked isn’t absent.

Why some councils aren’t here yet
Some councils publish their hazard maps under licences that don’t allow use in a paid report (non-commercial, or no derivatives), or with no licence stated. We ask those councils for permission, and add their maps when they agree.
