A floodplain is a level land area that is subject to periodic flooding from a contiguous body of water, such as a river, lake, or ocean. Floodplains are delineated by the expected frequency of flooding and are important in urban planning, agriculture, and environmental management.
A sewer is a system of pipes, containment areas, and treatment facilities designed for the disposal of waste and the containment of rainwater. This infrastructure plays a crucial role in maintaining public health and environmental quality by efficiently managing sewage and stormwater.
Wetlands, such as swamps, marshes, and bogs, are areas normally saturated with water. Development in these areas is often restricted due to their environmental importance.
