I. INTRODUCTION / PURPOSE The City of Hugo is faced with a need to provide additional reductions in runoff volume and pollutant loads in areas within the City that are tributary to Hardwood Creek, Clearwater Creek, and Bald Eagle Lake. These reductions are driven by either the requirements set out in the Total Maximum Daily Load (TMDL) for Hardwood Creek, Peltier Lake, Centerville Lake, and Bald Eagle Lake or through the implementation of the Rice Creek Watershed District (RCWD) rules governing development or redevelopment activities. In order for the City to anticipate the future cost and impact of these restrictions as well as identify the best projects that can be constructed to achieved these goals, there is a need to quantify the amount of infiltration and pollutant reduction necessary to meet future TMDL load allocations and RCWD plan requirements. To do this most effectively, this joint study between the City of Hugo and the RCWD has been undertaken. Based on the analyses that were undertaken and the planning process that was completed as part of this study, the following information has been developed. 1. An estimate of the amount of runoff volume reduction, storm water storage, total phosphorus, and suspended solids load reduction that needs to be provided to meet the waste load allocation goals assigned in the TMDLs and/or reductions that would be required as part of development or redevelopment. 2. A listing of the general Best Management Practices (BMPs) that are most capable of providing load reductions in a cost-effective and sustainable manner given the soil, topographic, land use, and other physical conditions that are present within this area. This review and evaluation took into consideration the various benefits of the BMPs, their corresponding cost, long-term maintenance, ownership considerations, anticipated sources of revenue for construction and maintenance, and other pertinent factors. A prioritized listing of the BMPs that are most suitable to address the storm water management needs for the RCWD and City is also provided. 3. A listing of site -specific projects that could be constructed to address regional storm water management as well as TMDL waste load allocation requirements. 4. A prioritized implementation plan that identifies potential projects that can be undertaken by both the City of Hugo and the RCWD to address the storm water management needs for this area. This prioritization takes into consideration the perspectives of stakeholders (MPCA, DNR, SWCD, City, RCWD, and others) relative to their interest in the listed projects.
