Name: CHShorelineHazard_120mBuffer

Display Field: OBJECTID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer contains the Shoreline Component as per Ontario Regulation 162/06. Regulation of the Shoreline of Lake Ontario will include: areas susceptible to Shoreline flooding to the 100 year flood level including wind setup and wave up-rush, areas susceptible to shoreline erosion, and dynamic beach processes. The limits of the hazards will be based on analysis of digital elevation mapping with respect to lake levels, slope stability and 100-year erosion limits. The estimated location of the Lake Ontario Shoreline in the Halton Region during a 100 Year Storm / flooding event has been estimated from the 76 mASL contour line. The 76 mASL 100-year flood level is determined from 1985 IGLD Instantaneous Water Level. An "Allowance" of 5m will be added to the estimated hazard limits to define the regulation limit. Site-specific analysis maybe required.
