I had someone ask me recently if there were any available source, maps, reports indicating the dates of flood incidents in New Orleans from May to October (2015 – 2018). Does anyone know where to look for historic flooding maps and/or data?

@sagarpreet, this might be interesting to add to https://github.com/publiclab/leaflet-environmental-layers if folks have some good data sources!

For Surge data, you can SURGEDAT for the Whole Gulf of Mexico. http://surge.srcc.lsu.edu/

Ezra Boyd would have known the answer to this in detail, I do miss him.

For New Orleans, i think the sustainable cities data has the 10 yr rain flood...

of course, FEMA has the HAZUS-MH https://www.fema.gov/media-library/assets/documents/5507

USGS has their estimation, based on photography (of course) https://pubs.usgs.gov/circ/1306/pdf/c1306_ch3_h.pdf

HUD map is based on NOAA data... https://www.nola.gov/getattachment/Safety-and-Permits/Floodplain-Management/Extent-Depth-of-Flooding-Katrina.pdf/
