The study effort began in 2012 with consulting assistance from HDR Engineering Inc. The effort is divided into three phases.
- Phase 1 is complete; it included background work to review current research and case studies from other parts of the country, forming an advisory structure for the study, including a Community Advisory Group, and developing a Public Involvement Plan.
- Phase 2 is complete; it included developing the study design and scoping the work to be completed as part of Phase 3, the implementation phase of the study.
- Phase 3 is underway; it includes field work, data analysis and modeling, and more public involvement. The study is expected to be complete in 2018.
