Consultants show 2040, 2070 and storm scenarios that inform local planning
Summary
The firm modeled 25 flooding scenarios incorporating NOAA sea-level curves, king tides and 100- and 500-year storm events; 2040 mirrors current king-tide impacts while 2070 (intermediate-high) shows substantially higher inundation in low-lying areas.
Baxter and Woodman presented modeled projections for 2040 and 2070 and explained how king tides and storm overlays change exposure. The consultant said the intermediate-high 2070 curve could raise levels by roughly three feet above a year-2000 baseline in the worst-case scenario; 2040 conditions are closer to current king-tide events.
"We ran 25 different flooding scenarios associated with sea level rise," Jeffrey Hiscox said, noting that the team compared a current-year baseline (2024) with future projections and layered storm rainfall (100- and 500-year events) to assess both coastal and pluvial flooding.
