The City of Imperial Beach is a low-lying coastal community just north of the U.S.-Mexico border that is vulnerable to flooding, particularly as sea level continues to rise. During seasonal peak tides and energetic wave events, the City already experiences flooding that impacts residents, businesses, and infrastructure. As part of its Resilient Futures project, CCCIA is teaming with the Imperial Beach community to upgrade the city’s flood alert capabilities and to develop tools to better prepare stakeholders for sea-level rise. The dedicated observing network and modeling system will provide the information needed for accurate, early flood warnings for vulnerable locations throughout the city, as well as the baseline information needed to develop and evaluate future sea-level rise adaptation strategies. The project is made possible through a generous contribution from the David C. Copley Foundation.
