Current Status

UTRCA Floodplain Update

In parallel to the Dingman Creek EA, the UTRCA has undertaken a comprehensive review of the floodplain hazards within the Dingman Creek Subwatershed. The UTRCA Regulatory Floodplain Update is expected to have implications on the limits of the floodplain and as a result planning and development applications within the floodplain area determined through the update. A preliminary hazard lands 'screening area' for the Dingman Creek Subwatershed has been developed by UTRCA. This map is included in the November 12, 2018 City of London report to Planning and Environment Committee and identifies the ‘screening area’, where further review and refinement will continue as options for engineered flood mitigation and/or policy solutions are assessed through a subsequent phase of the Dingman EA.

EA Phasing

The objectives of the Dingman EA study are to develop stormwater servicing solutions for lands that are scheduled for development. As a result, the UTRCA floodplain update has triggered the recommendation for the EA to be phased into two components (See map for Stage 1 lands). Stage 1 will address stormwater servicing requirements for select lands under the original EA scope of work. Stage 1 will only recommend municipal infrastructure for new development within tributaries outside of the area of influence of the updated Dingman Creek hazard lands. Stage 2 will be a continuation of the Master Plan EA process but will include a new or expanded problem statement to analyze potential engineering infrastructure for Dingman Creek (and tributaries not included in Stage 1) to mitigate flooding on impacted lands (as well as to improve access), all in consideration of the updated hazard information. During this time, the UTRCA will continue to confirm the extents of the natural hazards that are components of the UTRCA’s Regulation Limits.
