Emergency Response & Preparedness

Impacts of wave wash on the MCDD Marine Drive levee - 1996 flood

Impacts of wave wash on the MCDD Marine Drive levee – 1996 flood.

During high water and high rain events, the Districts implement the emergency response plans to keep levees and facilities functioning to protect life, property, and the environment. What is a high water or high rain event?

Flood event: The Columbia River or Columbia Slough has high water levels and is pushing against the levees. Our response to a flood event is described in detail in our Flood Emergency Action Plan, July 2016 Version 1.0.
Rain event: High rainfall in a short amount of time may raise water levels within the Districts and possibly cause flooding of certain areas in the Districts. Our internal stormwater management system is put to the test during this type of emergency event.
Note: Both of these events can happen at the same time or separately! 

During fall 2016 through summer 2017, MCDD staff will be developing a response plan for rain events. Staff is also working to improve emergency exercises and training. MCDD works closely with partner agencies to ensure a coordinated approach during future emergency events. Our key emergency partners include Multnomah County Emergency Management, Portland Bureau of Emergency Management, US Army Corps of Engineers emergency management, and the Port of Portland emergency management. The Districts also work closely with private partners including Graphic Packaging, Riverside Golf and Country Club, and others. If you have questions regarding the update, please contact Project Manager Angela Carkner at acarkner@mcdd.org or 503-281-5675 x 316.

Evacuation Plans
Though the Districts are a first responder in a flood event, evacuation is coordinated by your city.  To see the City of Portland evacuation plan specific to PEN 1, PEN 2, and MCDD, check out their webpage here. The Cities of Gresham, Fairview, and Troutdale explain basic evacuation protocols in their basic Emergency Operations Plans.
