Our team developed an extension of the existing Spring/Fishburne deep tunnel system and drop shaft to drain the street-level stormwater collection system into the deep tunnel and pump systems of the US 17 Spring/Fishburne Drainage Improvements Project. The design solution for this project includes a new drop shaft, vortex structure, approximately 900 LF of new tunnel to connect the area to the existing stormwater tunnel system, and approximately 425 LF of surface collection piping and associated drainage structures. This project will serve as the collection point for stormwater runoff from the approximately 27-acre Ehrhardt Street water basin that currently experiences substantial rainfall-driven and tidally influenced flooding.

We worked with the hospitals in this district to provide flooding relief. We designed drainage improvements to allow these healthcare facilities to better serve our community.
