The final report was presented a first time to the Alberni Valley and Bamfield Directors Committee on Novemand options for implementing floodplain mapping in the electoral areas were discussed at the JanuElectoral Area Directors Committee meeting.Ī peer-review process is underway Spring 2021 to ensure the methodology and research is sound and that the findings are accurate. A peer-review of the findings will take place in 2021.ĭuring the community review stage, the ACRD engaged in a number of public information campaigns including presentation of draft findings on the website, social media postings, surveys, and a public information event hosted by Northwest Hydraulic Consultants (NHC) on March 10, 2020. The project commenced in 2018 and has since moved through the stages of data collection, hydraulic modelling, flood mapping, community review, and in 2020, the finalized report, maps, and models. Prior to the completion of the Somass Watershed Flood Management Plan, the ACRD had minimal data and information to inform flood risk mitigation for new developments and the Zoning Bylaw provided only general guidance on flood construction levels not tailored to the local watershed and it's unique processes. The knowledge gained on this complex river, lake and tidal water system will help the community take a collaborative and informed approach to mitigation efforts because it provides greater certainty about potential flood events and associated impacts. It provides a more accurate baseline of anticipated flood risks if no actions are taken. The results from the Somass Watershed Flood Management Plan provide the first ever comprehensive flood risk information covering areas of Sproat Lake, Sproat River, Great Central Lake and the Ash River, and, additionally, provides updated flood risk information for the Alberni Inlet, Somass Estuary, Somass River, and the Stamp River where previous floodplain mapping was completed over 20 years ago.įlood mapping is an important step in watershed management planning. Jump to section: PROJECT TIMELINE | NEXT STEPS | DATA ANALYSIS | REPORT & MAPS | RESOURCES | CONTACT We have studied flood management for the Somass River System so we can plan effectively for its future. Rivers, lakes, and the inlet form the landscape of our region.
