Not all flooding in Maryland occurs because of the tides. As a matter of fact, across the state of Maryland, flooding happens every time it rains and there is a storm. This is referred to as precipitation, or rain based flooding, which is associated with storms. The impacts of these events can be flooding, decreased water quality, damage to infrastructure, low visibility, and hazardous conditions. The Maryland Department of Natural Resource’s, Chesapeake & Coastal Service is leading an initiative in collaboration with local partners to document the effect and impact of precipitation based and stormwater flooding in our communities. This information will help inform state and local recovery efforts.
