alert Interactive map upgrades begin Friday, April 11
The Coos County Flood and Natural Hazards Web Tool is undergoing a maintenance update and data layers may not appear. The map will return to normal service as soon as possible. Thank you for your patience during these improvements.

What is it?

The Coos County Flood and Natural Hazards Web Tool is an interactive map that shows which parts of Coos County are subject to various natural hazards. Overlays that show flood, tsunami, earthquake, river channel migration, and landslide hazards can be selected and viewed down to a scale of 1:4,514. Hazard overlays are draped on four different base maps, including one from high-quality lidar elevation data acquired by aerial survey in 2008. All hazard layers were developed by DOGAMI using consistent and documented methods and data. See Background page for details about each hazard layer.

The map will run on the Macintosh operating system, but users of Apple iOS devices (iPhone, iPod Touch, iPad) will need to obtain a Flash-enabled, third-party browser such as Skyfire or Puffin.
