Estimated Precipitation

◆Estimated Floods on the Flood Evacuation Map◆As floods are natural phenomena, we cannot predict when or to what extent they might occur. Even if riverbanks have been reinforced, they may not be strong enough to contain unpredictably excessive amounts of rainfall. Since soil deposits and thick vegetation growth can change the environment along rivers, the same amount of rainfall may cause different levels of flooding and water depths. Please be aware of and be prepared for any possible floods.
