+~~NOTOC~~
+====== Coastal Flood Mapping ======
+On December 9, the Coast Reporter ran [[https://www.coastreporter.net/local-news/coastal-flood-mapping-reveals-major-risks-for-infrastructure-11574231 |an article]] detailing how new SCRD maps "show just how close critical infrastructure is to the water’s edge".
+The article didn't really explain how to navigate the maps so here's what I found:
+  - Load the maps from [[https://maps.scrd.ca/Html5Viewer/Index.html?configBase=https%3A%2F%2Fmaps.scrd.ca%2FGeocortex%2FEssentials%2FREST%2Fsites%2Fpub_PropertyViewer%2Fviewers%2FPub_PropertyViewer%2Fvirtualdirectory%2FResources%2FConfig%2FDefault&layerTheme=&scale=288895.277144&basemap=&center=-13769114.510696897%2C6359406.893822151&layers=1UIjdp |here]] (the map's home page is [[https://www.scrd.ca/flood-maps/ |here]]).
+  - To declutter the information a bit, you can remove the "Inundation at Current Sea Level" layer by clicking on:
+     * "I want to" (top left corner)
+     * "Turn map layers on and off"
+     * "Environment" -> "Coastal Flood Mapping" -> "Inundation SLR Scenario"
+Here are two areas we all guessed would be affected first:
