Flood Hazard Management 
  • Provides for a better understanding of the river and floodplain system.
  • Problems addressed in a comprehensive, basin-wide manner. 
  • Directs future flood hazard management expenditures cost-effectively.

Planning Process 

  • The River and Flood Division works with the Flood Control Zone District Advisory Committee (FCZDAC).
  • Flooding problems are identified and characterized.
  • Consistent long-term flood hazard reduction strategies are recommended.
  • A Comprehensive Flood Hazard Management Plan (CFHMP) includes data collection, hydraulic modeling, alternatives analysis, floodplain mapping and meander limit  Requires extensive coordination with the public and other agencies throughout the planning process. 
  • Successful planning will reduce future flood damages and be supported by both the  community and agencies involved in floodplain issues.

Ongoing Flood Planning

Ongoing and recent flood planning efforts include analyses of:
  • Birch Bay
  • Canyon Creek
  • Glacier and Gallup Creeks
  • Johnson Creek
  • Jones Creek
  • Saar Creek
  • Sandy Point
  • Swift Creek

Comprehensive Flood Hazard Management Plan

The FCZD has focused on the Lower Nooksack River between Deming and Bellingham Bay, including the Everson-Sumas overflow corridor. 
  • The Lower Nooksack River Comprehensive Flood Hazard Management Plan (CFHMP) was adopted in 1999. 
  • The CFHMP identifies projects, programs, and other recommendations aimed at reducing future flood damages. 
  • Technical analyses to advance the recommendations in the CFHMP and integrate salmon recovery into resulting projects are documented in the following reports:
