This map is more of an exercise in using d3 with leaflet and plotting contour lines (obtained from the city's LIDAR data). The blue lines represent contours less than 5 m. Good thing the sea level rise shouldn't be this severe in the next 100 years or so. Though Nanaimo is hilly so there wouldn't be that much flooding.
