Maitland Conservation has undertaken a review of the existing gully erosion hazard mapping along the Lake Huron shoreline within the our area of jurisdiction. The previous gully erosion hazard mapping identified the ultimate extent of the slope hazard once each gully erodes to its mature form. This gully hazard mapping extended to Highway 21. However, the length of time that each gully would take to erode to its mature form at Highway 21 varies across the lakefront. As a result, Maitland Conservation has amended the mapping to reflect the gully erosion that could conservatively occur in the next 100 years, which is standard planning methodology for erosion hazards.

The amended gully erosion hazard mapping was approved by Maitland Conservation’s Board of Directors on June 20, 2018.

The amended gully erosion hazard mapping will also be circulated to the Huron County Planning Department with the recommendation that it be included in County and Municipal planning documents as natural hazard lands.

Purpose and Effect

It is the role of Conservation Authorities to regulate development within hazardous lands, pursuant to Ontario Regulation 164/06 made under the Conservation Authorities Act (R.S.O., 1990, chapter C.27).  Subject to the Regulation, Maitland Conservation must delineate on a series of maps the “Regulation Limit” for which development and/or site alteration must be approved by the Conservation Authority prior to work starting.

Maitland Conservation’s previous gully hazard mapping identified 88 gullies encompassing a total of 3,976.7 acres of land. As a result of our review, the area that is at risk over the next 100 years has been reduced to 1,334.3 acres of land. However, the erosion hazard area of some of the gullies have been identified as having an erosion limit larger than originally estimated.

Maps showing the changes to the gully erosion hazard areas have been posted on this website.
