Levee Ready Columbia Technical Advisory Subcommittee


The purpose of the Levee Ready Columbia technical advisory subcommittee (TASC) is to provide technical analysis and recommendations to the Oregon Solutions team. It is not the role of the TASC to make decisions. The TASC assists the Oregon Solutions team by performing the following functions:

  • Review and assess technical documents
  • Evaluate cost assessments
  • Evaluate alternative courses of action as identified by the Oregon Solutions team
  • Provide technical recommendations to the Oregon Solutions team
  • Share information
  • Vet technical information within each members’ parent organization
  • Educate stakeholders
