This Emergency Management System (EMS) layer contains both riverine and Lake based floodplain delineations. The storm event levels (5, 10, 25, 50, 100 year and regional) riverine floodplain delineations are based on existing hydraulic and hydrologic analysis. In general, engineered riverine floodplain is available for York Region, Municipality of Durham, and in Innisfil and Bradford-West Gwillimbury of Simcoe County. In general, estimated riverine floodplain is available for Ramara, Oro and in isolated locations within Uxbridge and Brock. The storm event levels (5 and 100 year) for Lake based floodplain, are based on existing coastal engineering analaysis.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 26917, "latestWkid": 26917, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5120900, "falseY": -9998100, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "© LAKE SIMCOE REGION CONSERVATION AUTHORITY, (insert current year).
