Shares are the proportion of the suburb's land area. Land where Landsat saw water in at least 1% of clear passes since 1987, excluding permanent water and filtered by DEA's confidence layer. Satellites miss flood peaks, so this is a floor, not a risk estimate; dense high-rise cores can still register tower shadow as water. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled. No open statutory flood or bushfire layer is published for Western Australia yet.
