Lake Erie Shoreline Hazard Mapping and Risk Assessment Study

Haldimand County, the Grand River Conservation Authority (GRCA), Long Point Region Conservation Authority (LPRCA) and the Niagara Peninsula Conservation Authority (NPCA) have initiated a study to update the Lake Erie shoreline flood, erosion and dynamic beach hazard mapping.

  •  The Grand River Conservation Authority (GRCA) is providing project management for an update to the Lake Erie shoreline flood, erosion and dynamic beach hazard mapping on behalf of Haldimand County, as well as the Long Point Region Conservation Authority (LPRCA) and the Niagara Peninsula Authority (NPCA).
  • Current shoreline hazard mapping for the County within LPRCA and GRCA jurisdictions was prepared in the late 1980s – early 1990s, while the mapping within the NPCA jurisdiction was updated in 2010.
  • Since completion of some of this work, provincial technical guidance has been updated (2001), and there have been legislative changes, including an updated Provincial Policy Statement (2014) under the Planning Act, and new regulations under the Conservation Authorities Act.
  • The purpose of this project is to update the Lake Erie shoreline flooding, erosion, and dynamic beach hazard mapping within Haldimand County to current mapping and technical standards.
  • Current and consistent hazard mapping across conservation authority jurisdictions is needed to support land use planning and permitting decisions in at-risk communities such as Dunnville and Port Maitland and the numerous shoreline resort areas within the County, and to support flood and erosion-related response and mitigation planning.
  • This is a technical study to update hazard mapping. Updates to conservation authority shoreline management plans or policies, Haldimand County’s Emergency Response Plan and Official Plan are outside the scope of this project.
  • Haldimand County has 87 km of Lake Erie shoreline, spanning parts of the jurisdictions of three conservation authorities – Grand River Conservation Authority (GRCA), Long Point Region Conservation Authority (LPRCA), and Niagara Peninsula Conservation Authority (NPCA).
  • The lakeshore area is made up of both agricultural lands and residential developments along Lakeshore Road. There are designated tourist residential areas that consist of a mix of seasonal and year-round cottages, homes and businesses. Some of these include Peacock Point, Featherstone Point, Hoover Point, Evans Point and Mohawk Point.
  • There are also many seasonal trailer parks and campgrounds within the lakeshore area. In addition to these privately owned facilities, there are several Provincial Parks, Conservation Areas and other public facilities such as Port Maitland where the Grand River spills into Lake Erie.
  • Dunnville is a town of 12,000 people, located on the Grand River about 7 km upstream from Lake Erie. Portions of Dunnville are at sufficiently low elevations where they are subject to Lake Erie related flood impacts, in addition to riverine flooding.
  • Two Public Education Centres will take place to help keep community members informed of the project. There will be no formal presentations; however, the sessions will provide an opportunity for landowners and members of the public to view project updates and mapping, provide comments, learn how to protect their property from flooding and erosion, and speak directly with County and Conservation Authority staff.
  • The public meetings planned for this project will also serve as the necessary public consultation process for revisions to regulated areas mapping under Ontario Regulations 150/06, 178/06 and 155/06 of the Conservation Authorities Act.
  • More information about Public Education Centres, including dates and locations, will be posted on the Haldimand County website as it becomes available
Note: The first Public Education Centre (PEC) was held on Saturday, September 15 at the Selkirk Centennial Community Centre. View the Project Information Posters shown at the PEC. Information regarding Public Education Centre #2 will be posted on this page and shared via County social media channels once details have been confirmed.
