Nearly $33 million in damage will be done to buildings along [Portland, Maine’s] low-lying — and high-traffic — Commercial Street area by 2050 because of steady sea level rise, a city architects group announced Tuesday (October 22, 2013).

That figure jumps to about $111 million by 2100. By that year, parcels where $46.4 million worth of buildings stand today will be “inundated on a daily basis [by high-tide flooding] if no changes are made.” The projections were part of a report released Tuesday by the Portland Society for Architecture, and compiled by the Scarborough-based Catalysis Adaptation Partners.
