Hurricane Katrina Leads To New Levee Safety Standards Nationwide

In August of 2005, Hurricane Katrina pummels the Gulf Coast for nearly a week, causing catastrophic damage from Florida to East Texas. In the aftermath, the Federal Emergency Management Agency (FEMA) and US Army Corps of Engineers (USACE) overhaul their levee safety standards, including significantly increasing the requirements of local levee managers.

Army Corps New Start Feasibility Study

The Columbia Corridor levee system is designated by the US Congress as a site for a US Army Corps New Start Feasibility Study, making it competitive for federal investment.


Senate Bill 431 is Passed

The Oregon State Legislature passes Senate Bill 431, creating a new special district responsible for operating, maintaining, and improving the 27-mile levee system that reduces the risk of flooding along the Columbia River in Multnomah County and contributing to improved water quality, habitat, and landscape resilience* in the managed floodplain.


New Special District

The new special district considers funding options for operations and upgrades to the flood-management infrastructure along the Columbia. (2023-24)
