Question

question 60 (8.25 points) flood insurance rate maps change periodically because flood controls, changes in terrain, and new construction can change the flow of water. residents petition the government to be removed from flood districts. flooding rarely strikes in the same place twice. flood maps do not change because the terrain is fixed.

Explanation:

Flood Insurance Rate Maps (FIRMs) are dynamic. Flood controls (like levees), terrain changes (due to erosion or construction - related earth - moving), and new construction (which can alter drainage patterns) all impact water flow. These factors change over time, so FIRMs must be updated. Residents petitioning is not the main reason for periodic changes. Flooding can and does strike the same place (e.g., areas with poor drainage). And terrain is not fixed (e.g., due to natural processes like river meandering or human - induced changes like mining).

Answer:

flood controls, changes in terrain, and new construction can change the flow of water.
