Estimate how much higher infrastructure might need to be built today to stay above projected mean sea level for its intended lifespan, based on a high-end ("worst-case" for planning) scenario.
Note: This calculator uses the NOAA 'High' scenario median projections from the 2022 Sea Level Rise Technical Report specifically for Boston, MA (relative to a 2000 baseline) as a plausible "worst-case" planning scenario. It calculates the projected rise from 2025 to the end of the lifespan.
This tool is for informational purposes only. Real-world projects require detailed, site-specific engineering assessments, consideration of local guidance, storm surge, tides, wave action, and appropriate safety factors.
