Amendments to Gully Erosion Hazard Mapping – Regulation Limit
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 existing gully erosion hazard mapping identifies the ultimate extent of the slope hazard once each gully erodes to its mature form. The existing gully hazard mapping extends 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 is planning to amend 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 will be presented for approval by Maitland Conservation’s Board of Directors on June 20, 2018 at 7:00 p.m. This meeting will be held at the Administration Centre located at 1093 Marietta St. in Wroxeter.
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 existing gully hazard mapping identifies 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.
