Being a coastal city, Metro Vancouver has many areas which are at risk to flooding in the event of a storm surge (sea level rises due to atmospheric pressure changes and wind associated with a storm). The maps attached in this post are a simplified representation of the immediate danger zone in a storm surge in Metro Vancouver (simplified as they do not take into account factors such as winds, tides, inland waterways etc). These maps are based on low elevation areas (at or below 10 metres) that lie up to 1 kilometre inland from the shoreline.

Accomplishment Statement:
In this lab, I used the following ArcGIS tools: buffers, reclassify, convert raster to polygon, overlay > intersect, and select by location.We also learned how to make a new feature class and how to make any edits to tables or features permanent alterations. These tools allowed me to come to conclusions about how elevation and proximity to the shoreline impact flooding risk in Vancouver.
