Torreyson Run Stormwater Improvements

The Torreyson Run watershed is one of the critical watersheds identified for stormwater capacity improvements. The watershed includes Westover Shopping District, Cardinal Elementary School, and four Civic Associations: Highland Park – Overlee Knolls, Leeway Overlee, Tara Leeway Heights, and Westover Village.

A new capacity project at Cardinal Elementary School currently in designwill help reduce flooding risk at Westover Shopping District and surrounding and downstream areas.
