| Abstract/Description or Keywords | This project is part of a larger initiative to develop a Lower Mainland Flood Management Strategy. The Fraser Basin Council is facilitating this collaborative process, which includes 26 local governments, the provincial and federal governments and numerous other partners. Following consultation with a number of key stakeholder communities in 2013, it was identified that a collaborative approach will be most effective in addressing the current conditions and future impacts from flooding on a regional perspective. Phase 1 comprises analysis, planning and consultation with the coordination and support of the Government of Canada, Provincial ministries, and 25 local governments within the Lower Mainland. Phase 2 will focus on development of options assessment and implementation. Phase 1 of this Lower Mainland Flood Management Strategy is comprised of the following projects: Project 1: Analysis of Flood Scenarios; Project 2: Regional Vulnerability Assessment; and Project 3: Flood Protection, Policies and Plans. This study focuses on Project 1 – Analysis of Flood Scenarios. The study area extends from White Rock to Squamish and from Hope to Richmond, and includes regional organizations such as Metro Vancouver, the Fraser Valley Regional District and select provincial ministries. The primary hazards considered for this study were coastal and Fraser River flooding. Due to the large extent of the study area and the data collection effort required on a regional level analysis, this study focused primarily on the use of existing flood hazard information from studies, reports and models that were readily available. Gaps and transfer of pertinent information, data and findings was analysed. Two coastal and two Fraser River flooding scenarios were identified to support the regional vulnerability assessment. Consultations were held with the Fraser Basin Councils’ technical committee on February 11 and March 10, 2015 and the criteria for selection of flood scenarios and associated flood levels were agreed. The flood scenarios selected acknowledge the impacts from sea level rise, climate change and site specific uncertainties on flood levels. |
