Rising seas threaten U.S. tax bases as private property falls below tidelines – Tidal flooding to swamp $34 billion in real estate within 30 years

PRINCETON, N.J., 8 September 2022 (Climate Central) – New analysis from Climate Central quantifies the risk of sea level rise to the tax bases of hundreds of coastal counties across 24 states and Washington, D.C. as more land falls beneath the tideline. By 2100 more than 1 million properties with a combined assessed value exceeding $108 billion are projected to be […]

Projections of annual counts of high-tide flooding (HTF) days for the NOAA Intermediate Sea Level Rise (SLR) scenario. The NOAA minor flooding threshold is used for Honolulu, San Diego and St. Petersburg. The NOAA moderate flooding threshold is used for Boston to highlight a threshold that is not yet routinely exceeded, which is not the case for the Boston minor threshold. The 50th percentile from the ensemble of projections (blue line) and the 10th–90th percentile range (blue shading, with the 90th percentile highlighted in orange) show increasing numbers of HTF days per year. The year of inflection (YOI, open black circle) for each projection corresponds to abrupt increases in the frequency of HTF days, which are highlighted by comparing the projected increases (Δ) over two adjacent ten-year periods (dashed and solid black lines).
