History and Experience

In 2006, sweeping changes in regulations for stormwater management were implemented by the Metropolitan St. Louis Sewer District (MSD) in St. Louis City as well as 59  municipalities within St. Louis County. These EPA-mandated regulatory changes, in St. Louis and across the country, prompted one of the most dramatic shifts in civil engineering design in decades. Stormwater infrastructure and its ongoing operating and maintenance costs are now one of the largest line items in a site development budget. Stormwater STL Founder and Managing Principal Steve Polk believes that thoroughly evaluating and managing compliance costs is imperative for property owners and managers. He also believes that this evaluation and management necessitates a diverse team, the makeup of which did not exist in St. Louis until 2008, when he founded Stormwater STL.

When you work with Steve and his staff, you’ll interact with a team of stormwater specialists with education, training and experience unmatched in the St. Louis area. Armed with degrees in civil engineering, environmental science, horticulture and planning and business, the Stormwater STL team is equipped to resolve all of your stormwater challenges.
