The L1 source is recommended by the Washington State Division of Natural Resources and the Emergency Management Division for "worst considered case" hazard analysis and inundation modeling, as a 2500-year event. This was used for example in the design of the new Ocosta Elementary School as a vertical evacuation structure, see
Using more recent topography
Since the Ocosta School project was completed, the 1/3 arcsecond topography available from
has been improved. The original topography was based on lidar that
captured tree tops rather than bare earth in places, as noted in
our report above. The newer topography shows more flooding in some regions:

contains subsampled topography used for these
recent simulations, and also 1-minute resolution ocean data from
The files below are for plotting maximum flow depth recorded over the simulation.
