Maps 2, 3, 4 - Small Multiple maps of single floodplains
- Created 3 small multiple maps for each floodplain and followed the same process as above
- Clipped the floodplains to the community district
- Colored coded AND properties with this Sql and created new layer out of them> AND (PROPERTY = 'AND 1' OR PROPERTY = 'AND 10' OR PROPERTY = 'AND 11' OR PROPERTY = 'AND 12' OR PROPERTY = 'AND 13' OR PROPERTY = 'AND 14' OR PROPERTY = 'AND 15' OR PROPERTY = 'AND 16' OR PROPERTY = 'AND 17' OR PROPERTY = 'AND 18' OR PROPERTY = 'AND 19' OR PROPERTY = 'AND 2' OR PROPERTY = 'AND 20' OR PROPERTY = 'AND 21' OR PROPERTY = 'AND 22' OR PROPERTY = 'AND 23' OR PROPERTY = 'AND 24' OR PROPERTY = 'AND 25' OR PROPERTY = 'AND 26' OR PROPERTY = 'AND 3' OR PROPERTY = 'AND 4' OR PROPERTY = 'AND 5' OR PROPERTY = 'AND 6' OR PROPERTY = 'AND 7' OR PROPERTY = 'AND 8' OR PROPERTY = 'AND 9'
- risk/total num of building
- rate of change over time
- Aggregate to blocks or CD and to average elevation there
- Load the NEW York City DEM (1 foot) integer raster 3.3.gb apply Z factor at correct latitude (40)
- Raster to Polygon - Table for each lot with average elevation (zonal statistics as table-mean) - mask to boundaries /reclass 1.5m and 3.0
- Import table in GIS make join btw table (min value elevation) with the table of the floods
Compare the rate of change All properties in the CDs run the same analysis
