Over the last century, Larchmont has seen a gradual sea level rise of about 12 inches, but according to a January 2019 analysis by Climate Central, a nonprofit, non-advocacy organization that researches climate impacts, there probably will be a far greater rise in this century.
The highest flood water level seen in the Larchmont area to date was 9 feet in 2012. The current projections are that a 6-foot high flood is about 22%-36% likely to happen between today and 2030.
With 6-foot high flood water, at least two miles of local roads would be at risk, along with a hazardous waste site in the area, a wastewater site, two EPA-listed sites, and many local residences.
The map below from Climate Central shows in red the Larchmont coastal property areas at risk from 6-foot high sea level rise. Larchmont land below 6 ft. is colored red to denote zones with high property value per acre, says Climate Central.
