Flooding Preparedness

Are you prepared for flooding? Learn how you can take steps to protect your home and family

This video discusses the history of flood events in Clackamas County and the differing scales in which they have unfolded, what life is like for a homeowner along the Sandy River and how climate change and glacial retreat could intensify future flooding events and increase their frequency.

This video explains erosion and channel migration and how it is often the most damaging component of flood events. It examines how channelized rivers can sometimes adversely affect the surrounding environment in unforeseeable ways and recent efforts to remap the flood hazard zones in the region.

This video examines a restoration site along the Sandy River that enhances the habitat for wildlife and works to reduce and spread out the force of the river through woody debris installations and reconnecting a side channel so the Sandy River has a release valve during high water events.

Flood insurance agent, Gail Moldovan-Trujillo explains three ways homeowners can reduce their rates and better protect their homes in the process. Elevation Certificates, proper venting, and other mitigation efforts like filling in foundations are examined.
