Engagement opportunity

The City of London is updating the regulatory flood hazard limit in Dingman Creek Watershed within the City of London Limits. You are being invited to a public meeting to learn more about the flood hazard limit update and how it may impact your property. The meeting will include a presentation from the project team, followed by an opportunity for the public to ask questions. The meeting presentation will be recorded and posted on this site.

Virtual meeting: Join us for a Zoom webinar online on Wednesday, January 21, 2026, at noon to provide an update on the project and information on what to expect during construction.

Date: Wednesday, January 21, 2026

Time: 12:00 p.m. to 1:00 p.m.

Format: Zoom webinar. Please register for the Dingman Creek Public Update Meeting.

About this project

The City of London is updating the regulatory flood hazard limit in Dingman Creek Watershed within the City of London Limits.

The Dingman Creek flood hazard update area is the proposed area shown on the following map.

Flood hazard limit update

Through the Dingman Stage 2 EA process, the regulatory flood hazard has been updated for Dingman Creek based on new data and modelling approaches. The City is updating Map 6 of the London Plan through an Official Plan Amendment, which includes updates to the underlying Place Type and Zoning layers. The project team will provide an overview of the changes to the flood hazard, the coordinated process that was undertaken between the City and Upper Thames River Conservation Authority, and the next steps and timelines for the project.

What is a Regulatory Flood Hazard?

A regulatory flood hazard is the official boundary that shows the area expected to flood during a severe storm event based on provincial standards in coordination with the local conservation authority. The flood hazard is used for land-use planning to keep people and property safe from flooding.

Stage 1 Study (Completed September 2020)

This Environmental Assessment (EA) was initiated to determine stormwater management solutions to facilitate development in south London for lands within the Urban Growth Boundary for the next 20 years. Finalization of floodplain updates delayed the project. To address imminent development pressure, the Stage 1 EA proceeded to identify preferred stormwater management strategies for lands not impacted by floodplain updates (Stage 1 Lands). Stage 2 lands were to be addressed in a future study.

The Environmental Assessment Project File for the Stage 1 Lands is available below.

Stage 2 Study (Initiated September 2021)

The purpose of this EA is to finalize the regulatory floodplain for Dingman Creek and assess potential flood mitigation and stormwater servicing alternatives to address imminent and future flooding and erosion risk within primarily the Stage 2 Lands.

Through the EA, a range of flood mitigation and stormwater management strategies will be developed. The recommended approach will guide future development, identify mitigative and adaptive flood control works and align with the City’s vision for the creek corridor to integrate natural heritage, stormwater management and recreational uses.
