"address the accuracy and completeness of the material contained in the EAW, potential impacts that may warrant further investigation before the project is commenced, and the need for an EIS on the proposed project." (MN Rules 4410.1600). Some of the comments included general remarks or recommendations. Such comments are noted for the record and further detail of the statements or recommendations is included in Appendix A. GOVERNMENT COMMENTS i Minnesota Pollution Control Agency (MPCA)- January 9, 2025 Regarding matters for which the Minnesota Pollution Control Agency (MPCA) has regulatory responsibility and other interests, the MPCA staff has the following comments for your consideration. Watershed • The proposed site is within the Minneapolis, St. Paul Priority A Surface water DWSMA. • With the proposed concentration of housing and roads, the development would benefit from having planned areas to put snow. o Planning to store snow in areas that won't increase icy areas as the pile melts will be the most beneficial. o The goal is to develop with winter maintenance in mind and using less salt. ■ With the proximity to wetlands and lakes, planning for winter maintenance during development may help keep the waterbody off the impaired waters list for chloride. • To better protect the waterbodies within the project boundary, there is an opportunity to do better than minimum runoff standards. o This could be done by designing for a lower runoff volume, more nutrient and sediment reductions, and provide wider vegetated buffers. o Include more details of planned infiltration areas and runoff rates. • Having more storage will help protect the housing areas from flooding. o With higher precipitation events expected, and wetland areas adjacent to properties, planning for higher precipitation events will prevent flooding of homes later. • Having a maintenance plan for the vegetated areas and stormwater BMP areas will ensure the BMPs continue to provide benefit. o This includes assigning who will oversee maintenance and what is allowed. o Protecting the buffered areas from mowing and having a vegetation management plan could reduce future landowner conflicts. Response: These recommendations will be taken into consideration during the city's site plan review process. Onsite management plans will be developed moving forward regarding the maintenance of the site including snow removal and chloride management. A stormwater maintenance agreement will be required by the city for the longterm maintenance of the BMP's. Wastewater 0
