A 100-year flood event occurred in Blaine County, ID in the late spring/early summer of 2017, impacting the unincorporated county and the cities. The last major flood had occurred 11 years prior, in 2006. Planning staff from the cities and county share their lessons learned / best practices for administering a local floodplain ordinance and for working with property owners and outside agencies before, during, and post-flood event.

100-year flood events are the “big”, major flood event that local floodplain ordinances are written for. Part 1 of the session will cover major lessons learned from day to day implementation of the local ordinance and also what it’s like to see the impacts of a 100-year flood on properties where the regulations were implemented well vs. properties in the floodplain where older, less restrictive versions of the regulations were implemented and/or development occurred before the jurisdiction adopted a local floodplain ordinance. Part 2 of the session will focus on lessons learned in administering an ordinance during the “big” flood, what it’s like coordinating with state and federal agencies and property owners impacted by the flood, lessons learned/takeaways, etc.

This session will provide valuable information for floodplain administrators and planning staff and commissioners who haven’t yet experienced a 100-year flood event in their community and/or those interested in learning about the experience of implementing floodplain ordinances in general.
