Sourced, cited and dated
- Cited to the code section. Every standard shows the section of the city's adopted municipal code it came from.
- Sourced and dated. The last page lists every source and the date we read it: the city's official map and code, and FEMA's National Flood Hazard Layer.
- Checked before sale. Before a city goes on sale, a second reviewer checks its data against the code. Only cities that pass go on sale.
