Flooding

Keep track of the normal water level and history. It is important that you know how water levels normally are, so you can see when the water begins to rise. If you suspect that a flood is underway, it is important that you follow weather forecasts. Your municipality may also provide information about water situation, and when a possible flood is estimated to reach your area. Temporary barriers can stop a minor flood. The easiest is to build a sand or earth embankment and cover it with plastic. Rent or purchase pumps well before the floods come and review the terms of your home insurance.
