FEMA Coastal Floodplain Map Update

The Federal Emergency Management Agency (FEMA) and Oregon Department of Geology and Mineral Industries (DOGAMI) have created new preliminary flood maps along the coastal areas of Lane County. The purpose of this website is to share information about this project. All documents and other materials related to this project will be posted as they are available.

This project is in its preliminary phase. An open house was held with partners on September 18, 2018. The next step is a FEMA initiated 90 - day appeal period estimated to occur November - January. View the next step documents here.
