The primary risk is coastal flooding, which could affect low-lying areas like Seacoast Drive in Imperial Beach. The combination of high tides, strong waves, and elevated sea levels poses a threat to infrastructure and homes. Groundwater rise, driven by ocean tides, is another concern, with projections indicating near-daily flooding by 2100 under intermediate sea-level rise scenarios. Beaches facing south or with disrupted sand movement, such as those in Long Beach and Newport Beach, have already experienced significant damage. Imperial Beach’s geography may offer some protection, but experts caution that the city remains vulnerable to severe winter weather events.
