The level of the oceans' surface is known as the sea level. Sea level is also used to measure the height of certain cities. For example, Big Bear, CA is <span> 6,750 feet above sea level.</span>
You could make like a building somewhere high so when everyone gets a warning that a flood is coming they can go and leave there let’s there or like a boat like Noah’s arc
