Meet Our Board

Paul Mueller, President
CESSWI

Paul Mueller is an erosion control and stormwater inspector with St. Charles County's Department of Community Development. He conducts inspections at construction sites and stormwater facilities in unincorporated St. Charles County, Missouri in the rapidly growing St. Louis metropolitan area.

Mr. Mueller's experience with erosion control inspections began when he started working with the Missouri Department of Natural Resources in the early 90s. During that time, he worked with EPA Region 7 inspectors on several joint inspections. When Phase II stormwater was implemented, he worked with communities in developing their stormwater management plans. In 2016, he became the chief erosion control inspector for St. Charles County, where he also helps in the management of their MS-4 program.

Mr. Mueller has a Bachelor of Science degree from Iowa State University. He is a Certified Erosion, Sediment, and Stormwater Inspector (CESSWI). He was a revision team member for the third revision of the Missouri and Kansas "Protecting Water Quality Guide." He has participated on several committees in the drafting of land disturbance and general stormwater permits.

Mr. Mueller is active in his home community. He serves on the Board of Directors and is a retired Lieutenant/Engineer with the local fire district, where he was a state-certified instructor in firefighting and hazardous materials.

Josh Hanson, CPESC, CPSWQ, Vice President

Josh started his stormwater compliance career in the Mid-Atlantic region and was a member of the Mid-Atlantic chapter of the IECA before relocating to the Midwest. He has performed stormwater compliance services or consulted in 30 states and the District of Columbia. For Olsson, he acts as the stormwater compliance technical advisor for the Olsson footprint. As part of his responsibilities, he sees the IECA as an industry leader in technical advances in the erosion control and stormwater management fields. He encourages attendance at conferences in local IECA chapters to better educate regional teams on regulatory issues, technological advances and new and innovative BMPs to heighten the quality of their designs

Steven W. Polk, PE, EMBA, Secretary

Steven founded Stormwater STL LLC in 2008 to help commercial, industrial, and institutional property owners protect their investments in post-construction stormwater BMPs (Best Management Practices), more recently referred to as SCMs (Stormwater Control Measures). Our customer list now includes more than 100 of the most respected and recognizable names in the St. Louis development community.

According to Steve, “The foundation of our success is our collaborative approach to projects. Firms that continue to work in their specific silo of experience are no longer positioned to offer the best stormwater compliance advice.”

Our stormwater compliance specialists hold degrees in Civil Engineering, Environmental Science and Horticulture. While inspections of both above-ground and below-grade BMPs are the core of our business, the most rapidly growing segments of our business include native plant stewardship and on-demand maintenance for a wide variety of BMPs.

Steve’s commitment to the advancement of this specialized market has been rewarded with dozens of invitations to share his post-construction BMP knowledge with local, regional, and national stormwater management associations and has quickly established Steve as the local leader in this rapidly evolving discipline.

Samantha McKee

I started my stormwater journey around 6 years ago with Olsson in the La Vista, NE office. I have a BS in Environmental Science from the University of Missouri Kansas City. At the beginning of my journey, I started out as a stormwater inspector covering all different types of sites such as pad, linear, roadway, SID’s, data centers, and renewable projects. I took a strong liking to this field and wanted to grow my knowledge as quickly as possible. After sometime I took over the stormwater program in La Vista/Omaha and began to grow our foot print. I started leading onsite meetings regarding stormwater compliance issues, meeting with the City and State, hiring and training new team members, meeting with our Civil team on a regular basis, submitting proposals and writing SWPPPs. This past year I took over our Lincoln, NE team and have been focusing on trainings, being involved in plan review, writing and reviewing of SWPPPs and the day to day responsibilities. I am currently working on obtaining the CPESC.
