Floodplain Mapping Projects

Brown County


Due to restrictions and caution surrounding COVID-19, the Brown County Public Open House will be held virtually using ZOOM technology. Residents in Brown County may sign up for an individual 15-minute virtual session from 1:00 to 6:00 PM on June 4, 2020. Login information for the ZOOM session will be sent following sign up. In addition to the virtual open house, a 30-minute presentation has been recorded to answer many of the most common questions we receive.
