Flooding

St. Armands Key is a low-lying, barrier island.  It is also bowl-shaped, with a generally lower elevation in the interior and a slightly higher elevation in most places around the perimeter.  It is therefore prone to flooding and pump stations have been installed because gravity drains alone were insufficient.  However, those pump stations were overwhelmed and/or not fully operational during the flooding events of 2023 and 2024.
