CENTERVILLE - DOWNTOWN REDEVELOPMENT Item-by-Item Response ITEM 10. COVER TYPES AGENCIES/INDMDUALS COMMENTING: RCWD 1. Comment Summary: The approximate proposed wetland impacts of 0.38 acres will be subject to WCA sequencing and mitigation requirements through the District permitting process. In addition, wetlands before and after construction should at a minimum be equal given WCA requirements. Response: Comment acknowledged. Item 12 of the EAW states that the developer will need to work with the RCWD regarding potential impacts to the wetland and that any impacts will be subject to the Wetland Conservation Act requirement for replacement at a 2: 1 ratio. ITEM 12. PHYSICAL IMPACTS TO WATER RESOURCES AGENCIES/INDIVIDUALS COMMENnNG: MET COUNCIL 1. Comment Summary: The project proposes to eliminate the only wetland within the proposed 37-acre redevelopment area and to excavate the depression for use as a stormwater treatment basin. Elimination is contrary to Council Policies that promote protection of such water resources. Council policies recommend utilization of best wetland management practices that result in maintenance and improvement of water quality, control of runoff rates and volumes to reduce erosion and flooding, and preservation of the designated beneficial uses of such natural basins. This wetland area should be avoided and proposed stormwater detention and treatment facilities should be accommodated elsewhere on or off the immediate site. The ongoing CSAH 14 project in the City already resulted in elimination of several acres of wetland in the City. Since Clearwater Creek is impaired for fish and invertebrate according to the biotic integrity (lBI), further losses in the City could incrementally worsen the Creeks IBI. Response: The developer will be required to comply with the Wetland Conservation Act (WCA). As indicated above and in the EAW, the developer will need to work with the Rice Creek Watershed District (RCWD) regarding potential impacts to the wetland and any mitigation that will be required. RCWD is the Local Government Unit (LGU) responsible for the administration of the WCA. ITEM 17. WATER QUALITY: SURFACE WATER RUNOFF AGENCIES/INDIVIDUALS COMMENTING: RCWD, MET COUNCIL 1. Comment Summary: As part of the Centerville Lake TMDL, the District has completed a nutrient budget analysis for Centerville Lake. In addition, preliminary analysis completed by the District indicates that the proposed District rule will allow the city to redevelop the downtown area while meeting the Centerville TMDL goal. This information has been shared with the City of Centerville, and as a result, the District does not find it necessary for the city to complete a nutrient budget analysis separate from the Districts. With that said, as noted in the EAW, Clearwater Creek is also listed as an impaired waterbody due to biological impairment and the city should attempt to reduce stormwater volume and rates entering the creek to the maximum extent practicable.
