Urbanization typically leads to an increase in impervious surfaces such as roads, buildings, and parking lots. This reduces the amount of water that can infiltrate into the ground, leading to more runoff during rainfall events. Consequently, the flood peak rises higher and faster than before, as the water is more quickly directed into streams and rivers.
