4 <br /> <br />west. Future development on this second parcel will potentially require an additional <br />infiltration basin. <br /> <br />The runoff rates for the site will be lower for all discharge locations and all storm events. <br /> <br /> <br />Stormwater Pollution Prevention <br /> <br />The Grading, Drainage, and Erosion Control Plan calls for inlet protections, silt fence on <br />all downgradient perimeters, a rock construction exit, and riprap for energy dissipation at <br />an outfall to the stormwater pond. <br /> <br />The Stormwater Pollution Prevention Plan (SWPPP) must be submitted with the final <br />construction plans. The SWPPP must include a concrete washout location, a note that <br />stabilization must be completed within 7 days of construction activity ceasing (due to <br />proximity to impaired waters), contact info and credentials for the project inspector, and <br />all other information required by the NPDES permit. <br /> <br />The plan calls for Category 3 erosion blanket. This should be updated to reflect the <br />current 2020 Mn DOT specs for erosion control products. The City requires natural net <br />erosion blanket. <br /> <br />Plans have been changed to reflect current Mn DOT specs, noting use of Category 20 <br />natural net erosion blanket. <br /> <br /> <br />Flood Plain <br /> <br />Site does not fall within the flood management zone. <br /> <br />Shoreland District <br /> <br />Site does not fall within the Shoreland District. <br /> <br />Wetlands <br /> <br />There are no wetlands indicated on this site in the Natonional Wetlands Inventory. No <br />wetland impacts are proposed for this project. <br /> <br />Greenway System, Parks and Trails <br /> <br />There is a proposed trail location noted in the 2040 Comprehensive Plan for the area <br />north of this site across Apollo Drive. Also, a stormwater drainage route is identified on <br />the project site in Greenway System Plan. <br /> <br />
