Peter R. Willenbring, PE Water Resources, Vice President involved designing and constructing storm sewer or open channel drainage systems, dams/impoundments/levees, stormwater treatment facilities, or lake restoration improvements. • Completed hydrologic feasibility studies of over 100 areas that were experiencing flooding problems, developed plans and specifications for improvements, and provided bidding and construction management services to correct these problems. Water Quality Management, Planning and Lake Restoration • Developed Water Quality Management Plan and/or Non-degradation plans for the Cities of Hugo, Circle Pines, Coon Rapids, Maple Grove, Rosemount, Richfield, Shakopee, and others. These documents quantified existing and anticipated future pollutant loadings and outlined a plan to mitigate the water quality impacts that had or would be created by any past or future development. • Designed, constructed, and operated in multiple locations a portable flocculation treatment system capable of removing in excess of 90% of the phosphorus and other pollutants from stormwater treated by the system. This removal efficiency is significantly higher than the maximum removal efficiency of 50-60 percent commonly anticipated for conventional treatment devices. • Implemented Golden Lake Water Quality Improvement Demonstration Project in the City of Circle Pines. The project demonstrated the viability and cost effectiveness of using flocculation treatment to reduce phosphorus levels in stormwater runoff. • Prepared hundreds of permit applications and supportive technical information to agencies such as the Minnesota Department of Natural Resources, the US Army Corps of Engineers, and the Minnesota Pollution Control Agency for work in public waters, wetlands and navigable waters. • Prepared dozens of environmental assessments for larger scale projects that have the potential for environmental impact. These assessments were completed consistent with the requirements of the Minnesota Environmental Quality Board rules. Flood Control • Completed detailed hydrologic analyses, reports, and other supportive documentation needed to correct/update FEMA floodplain maps for dozens of communities in the state of Minnesota. Wetland Management • Completed wetland delineation training program administered by the State of Minnesota Board of Water and Soil Resources. • Prepared dozens of wetland mitigation, wetland replacement and/or wetland banking plans in conformance with regional, state WSB and federal regulations. ��77
