The US National Oceanic and Atmospheric Administration (NOAA) reported on 10 July that coastal communities across the US continued to see increased high tide flooding last year, forcing residents and visitors to deal with flooded shorelines, streets and basements. This is a trend that is expected to continue this year. Elevated water levels affected coastal economies, tourism and crucial infrastructure like septic systems and storm-water systems, according to the new NOAA document.

High tide flooding, often referred to as ‘nuisance’ or ‘sunny day’ flooding, is increasingly common due to years of relative sea level increases. It no longer takes a strong storm or a hurricane to cause flooding in many coastal areas.
