The Lower Nooksack River Comprehensive Flood Hazard Management Plan (CFHMP) provides detailed recommendations for flood hazard reduction strategies and projects along the lower Nooksack River. The Whatcom County Flood Control Zone District adopted the CFHMP in 1999 and is currently working to update the plan and integrate flood hazard reduction strategies with the needs of salmon and agriculture. The River and Flood Division has established a Floodplain Integrated Planning (FLIP) Team to assist in updating the plan.
The CFHMP includes four reaches on the river from Deming to Bellingham Bay and a fifth reach representing the Nooksack River overflow from Everson to Sumas (see map below). Planning work is organized by reach. Current planning efforts are focused on Reach 2 and on the Everson Flow Split vicinity, which includes lower Reach 4 and Reach 5.
The CFHMP Update will include a process for public input at key points during the planning. A public meeting was initially scheduled for January 2020 but was canceled due to bad weather. Rescheduling the public meeting has been postponed due to COVID restrictions and the November 2021 floods.
The FLIP process provides the framework for achieving the integrated floodplain management goals for the Lower Nooksack River and its floodplain.
The FLIP process began in 2017 and is an ongoing collaborative effort among the County, the tribes, and many stakeholders. There is not an anticipated completion date for the Updated CFHMP at this time.
The FLIP team includes representatives from:
The FLIP process is led by a Steering Committee with representation from the Whatcom County Flood Control Zone District (FCZD), Lummi Nation, Nooksack Indian Tribe, Ag Water Board, the cities in the Nooksack River floodplain, and the Washington State Department of Ecology. The committee embraces the Floodplains by Design principles of integrating multiple interests and applies them to the Nooksack River watershed.
