Hogpen Slough Project

• Project typeStormwater Treatment Area (STA)
• Contractor nameWGI (Design and Permitting)

Located north of Walton Road and west of Lennard Road, the Hogpen Slough Stormwater Treatment Area (STA) project will treat runoff from areas like Savanna Preserve State Park, Savannah Club and Spanish Lakes Golf Village. Stormwater treatment areas are constructed wetlands designed to filter nutrients by promoting plant growth and the formation of peat soil. Besides helping with flood protection, their primary function is to remove phosphorus from urban and agricultural runoff before it flows into the North Fork of the St. Lucie River.

Design for the Hogpen Slough stormwater treatment area (STA) project is underway. The design and permitting phases are anticipated to be completed by Fall 2025 with construction expected to begin in early 2026.

Employees from the City of Port St. Lucie, WGI survey and environmental employees, and a WIRX geotechnical team will be in the area of the existing detention areas over the next few weeks gathering information for design. This work will include but is not limited to the following:

• Design Survey Environmental Report
• Geotechnical Exploration and Evaluation
• Environmental Reports
• Preliminary Hydrologic and Hydraulic (H&H) Modeling and Drainage Report including Pollutant Load Reduction Modeline Site Plan of the STA
• Preliminary Construction Plan Preparation

The City would like to thank the City Council for their support and prioritization of this project. The City Council helped make the funding possible and St. Lucie County is matching funds for the design.
