The facility contributes to community resilience against heavy rainfall events common in the Gulf Coast climate.

Theodore, Alabama, is located in the Gulf Coast region, characterized by high annual rainfall and a flat topography that can lead to localized flooding. Stormwater runoff from industrial and urban areas can carry pollutants such as sediment, oil, grease, and heavy metals into nearby water bodies, including Mobile Bay and the Gulf of Mexico. The Kooiman Road Pit outfall likely discharges into a drainage system that ultimately reaches these sensitive coastal ecosystems, which support fisheries and wildlife. Effective stormwater management is critical to protect water quality and aquatic habitats in this region.
