Flood Risk Evaluation and Flood Control Solutions
Flooding in Prince George occurs as a result of either high freshet flows or ice-related causes. Typically, the freshet causes the more severe flooding in the Fraser River whereas ice-related flooding, particularly during freeze-up, is the more critical condition for the Nechako River. The ice jam flooding in Prince George during the winter of 2007-2008 raised questions about the vulnerability of flood prone areas within the City and resulted in calls for long term solutions to protect properties within the 200-year floodplain.
The City of Prince George retained Northwest Hydraulic Consultants Ltd (nhc) along with a team of sub-consultants consisting of McElhanney Consulting Services Ltd (MCSL), Environmental Dynamics Inc (EDI), M. Miles and Associates Ltd (MMA) and Kevin Brown Communications Ltd to carry out a flood risk evaluation and develop flood control solutions for the City. The main goals included:
- Prepare a comprehensive flood risk evaluation, incorporating a threat and consequence analysis and developing and prioritizing flood relief options.
- Following a public consultation process, select suitable flood control solutions and develop conceptual level designs, including cost estimates and approval requirements.
- Update the existing floodplain maps prepared in 1997.
