S. 5386 is a plan by the government to make better maps showing where floods happen in cities, so people, businesses, and towns can see the risk and prepare better; it gives money to help make these maps, but some worry that there isn't enough money to make really good maps for everyone who needs them.

The bill wants to help cities make better maps to show where floods might happen so people can be safer, like when rain makes too much water in streets and homes. It plans to give some money to help, but the money might not be enough for small cities, and maps could still be hard to understand.
