Mapnik style (flood.xml) for the FEMA NFHL data for Flood Plain Projector
Includes an example config for TileStache for serving the tiles.
This style assumes that the NFHL data has been pulled in through the FEMA NFHL PostGIS load script written by the Flood Plain Projector team.
You will need to change the user, password, and dbname parameters in flood.xml according to the user you are using for PostGIS and where your NFHL data is stored.
