Updated Floodplain Mapping
The Region of Durham has partnered with the Ganaraska Region Conservation Authority (GRCA) to update floodplain mapping for Lovekin, Bouchette Point and Port Granby Creeks, as well as the northwestern portion of the Ganaraska River watershed.
Updating the floodplain mapping for these creek systems is important as the current mapping is 46 years old. The GRCA will be hosting an upcoming Public Information Centre (PIC) to share the updated floodplain mapping for these watersheds.
Floodplain mapping information is critical to help identify areas that may be at risk of flooding during severe storms, to assist the community with emergency preparedness, and is also an important municipal land use planning tool.
Draft floodplain mapping will be available on GRCA’s website for viewing starting on January 18th, 2024, in advance of the PIC. Comments can be made within the mapping viewer and will be received until February 18th, 2024.
This project is being funded in part by the Flood Hazard Identification & Mapping Program (FHIMP).
