Stormwater Management

Stormwater Management is the most important infrastructure element on St. Armands Key.  

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.

“This is not the first nor last time St. Armands will flood. There is an elevation issue. If the scientists are right, we will spend a lot more of our future trying to find methods to keep water out”
