At the August 21, 2017 R.M. Council meeting, a motion was passed to undertake a two-dimensional (2D) hydraulic modelling and mapping study of the South Saskatchewan River flood plain to determine what areas of the flood plain are floodway (no or limited development allowed) and flood fringe (development may be allowed subject to conditions); a map of the study area can be found HERE. On April 16, 2018 Barr Engineering was selected by R.M. Council as the consultant for the study.
The R.M. successfully applied for funding under the National Disaster Mitigation Program – Stream 2: Flood Mapping, administered by Public Safety Canada. The federal government paid for 50% of the project costs and the provincial government paid the other 50% through the Flood Damage Reduction Program.
A copy of the final study can be found HERE. The modelling determined that some areas are considered flood fringe where development can occur subject to development conditions, however the majority of the floodplain has been identified as floodway where development cannot occur.
Next steps include amending current R.M. policies to allow for development in flood fringe areas, public consultation with affected ratepayers and additional discussions with provincial agencies on emergency management and the implementation of provincial flood regulations. This work is expected to begin in fall 2020.
The R.M. is also completing a feasibility study for flood mitigation related to three different levee options in the floodplain.
