• Edina - for two recent street reconstruction project areas, we completed a study of the area and worked directly with watershed staff to identify what types of BMPs and treatment levels would help meet their goals and be eligible for cost share funding. The results were BMPs including under- road infiltration chambers, PaveDrain porous pavement on an entire street for the first project, and more than 20 tree trenches on the second. • St. Paul - working directly with the local watershed, we coordinated a regional treatment iron enhanced sand filter bench on an existing pond system to meet treatment needs of project. The approach Is similar • Burnsville - for the past five years, we have been completing an in all cases: to budget XP-SWMM hydraulic analysis of the storm sewer system capacity of local street areas in the year before the City begins plans for the project to for and complete a identify any necessary upgrades. stormwater-focused • Forest Lake- we are currently completing a feasibility study of potential BMP locations for the watershed and in close coordination with the City. study of a future street The report will be used to apply for a grant in 2016 with the intent to reconstruction or complete the construction in 2018, pending a successful grant award. improvement project in The approach is similar in all cases: to budget for and complete a stormwater-foc used study of a future street reconstruction or improvement the year or two prior to project in the year or two prior to the planned project. This sets the stage for more innovative approaches and opens the door to potential funding at the the planned project. watershed and state levels. Task 2: Understand the City's Current Surface Water Management Plan Based on our project team's history with the City's most recent 2013 plan update, SEH is uniquely qualified to provide an unparalleled understanding of the current CSWMP and past City issues. While some may see our team's familiarly with the current plan as a hindrance to adopting changes, we fully embrace working with individuals who bring a fresh perspective and support new and innovative ideas and solutions. SEH will be able to hit theground running based on our recent planning experience and knowledge gained in the development of the 2013 CSWMP. We can deliver the best value by building upon our previous work with the 2013 CSWMP and focusing our efforts on updating the plan with the most recent mapping data, such as current land use, floodplain boundaries and impaired waters, and incorporating the most recent capital improvement projects, new flooding issue areas and new studies completed since 2013. Our strategy to evaluate and incorporate existing modeling data is not to complete modeling updates throughout the entire City, but rather to work with City staff to identify detailed modeling efforts that could occur as an amendment to this scope in problem areas and/or future street improvement areas. The potential detailed modeling efforts in specific areas are typically of greater value in evaluating potential improvements and solutions than city-wide, regional sub-watershed modeling efforts. In Burnsville, for example, as part of our overall citywide XP-SWMM model update, the City has identified a dozen or so specific areas that will need more SHORT ELLIOTT HENDRICKSON INC. 6
