Since retention ponds stay filled year-round, they require a secondary source of water that remains steady when rainfall is scarce. In particular, coastal wetlands that serve as natural buffers against flooding and storm surges could be lost due to rising sea levels or increased surface runoff in wetland areas leading to saltwater intrusion into freshwater systems.
