The data currently includes both This feature class depicts floodplains regulated by the Authority as the Riverine Flood Hazard under the Generic Regulation of the Conservation Authorities Act (Ontario Regulation 97/04). regulatory floodplains, and advisory floodplains. This dataset was developed by creating polygons from the polyline geometry of the flood lines in the Authority's Riverine Floodplain Mapping database.

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This feature class depicts the top-of-slope features associated with valleylands regulated by the Authority as the Apparent Valley Riverine Erosion Hazard under the Generic Regulation of the Conservation Authorities Act known as Ontario Regulation 97/04. Top-of-slopes indicate the transition from an apparent valley wall, which rise to more than 3 meters from the toe of slope or associated watercourse, to the adjacent table lands. Top of slopes are categorized by their stability. Valley walls that exhibit slopes greater than 3:1 are deemed unstable. Top of slopes were identified and categorized through the topographic interpretation of a classified slope surface, DEM, 1m contours, and DTM breaklines.</SPAN></P></DIV></DIV></DIV>
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This feature class depicts the allowance/setback applied to top-of-slope features associated with defining valleylands regulated by the Authority as the Apparent Valley Riverine Erosion Hazard under the Generic Regulation of the Conservation Authorities Act known as Ontario Regulation 97/04. A 15 metre setback was applied in the form of a buffer to these top of slope features for regulation mapping purposes regardless of their stability status since it was determined that there was not an accurate enough method of predicting stable tops via desktop analysis that the Authority would be confident defending other than a proper geotechnical review. The purpose of the allowance generated as part of the regulation mapping is to identify lands adjacent to the actaul hazard feature that are potentially prone to erosion so actual setbacks may differ as a result of the review process depending on the stability of the slope and site specific circumstances.</SPAN></P></DIV></DIV></DIV>
