Risk Mapping Assessment and Planning

Ecology is the RiskMAP coordinating agency assisting Federal Emergency Management Agency (FEMA) in the implementation of the RiskMAP concept.

The vision for RiskMAP is to deliver quality data that increases public awareness and leads to action that reduces risk to life and property. RiskMAP builds on flood hazard data and maps produced during the Flood Map Modernization (Map Mod) program.

Ecology will soon be providing documents and information intended to inform and educate everyone interested in flood hazard maps, tools, and information including:

  • The RiskMAP Vision
  • Washington's State RiskMAP Team
  • Current RiskMAP projects and schedules
  • Data, maps, and information
  • Products
