This feature class contains polygon representations of modeled coastal flood extents developed by Kerr Wood Leidal (KWL) as part of the Coastal Flood Mapping Project (2021).<\/SPAN><\/P>

The flood extents are derived from the regulatory coastal flood limit linework and represent the spatial extent of inundation under the modeled scenario, which includes:<\/SPAN><\/P>

- 0.5% Annual Exceedance Probability (AEP) storm event (200-year return period)<\/SPAN><\/P>

- 1.0 m sea level rise<\/SPAN><\/P>

- 0.6 m freeboard allowance<\/SPAN><\/P>

The polygons were generated for mapping and visualization purposes using the flood limit linework and shoreline closure, and do not represent dynamic flood timing or wave processes across the study area.<\/SPAN><\/P>

In KWL documentation, these extents are described as \u201cregulatory floodplain extents\u201d because they are used to inform flood construction levels (FCLs) and support regulatory planning. However, within CVRD systems, this dataset is maintained as a representation of modeled flood inundation (water extent), separate from regulatory development boundaries.<\/SPAN><\/P>

Users should be aware that the flood extents represent a modeled scenario and may not reflect all local conditions or future changes. Flood levels may vary spatially and temporally, and peak water levels may not occur simultaneously across the entire mapped area.<\/SPAN><\/P>

For regulatory development constraints, refer to the Building_DesignatedFloodplains dataset, which incorporates bylaw-based hazard areas including coastal setbacks and additional planning considerations.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 26910, "latestWkid": 26910, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5120900, "falseY": -9998100, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "Kerr Wood Leidal Associates Ltd.
