and more capacity, the designation of public water wetland should be consistently used <br />throughout the EAW. With the problems of water quality noted, is it possible that novel <br />approaches could be considered for enhancing the development, especially those that <br />would provide more habitat for emergent marsh vegetation along the shoreline. <br />Establishing marshy habitat has been quite successful elsewhere in the metropolitan area <br />and consideration should be made of this possibility. <br /> <br />Response 1: <br />Mirror Lake will be referred to, where applicable, as a “public water wetland” in <br />order to be consistent with its classification. See the Response to Comment 1.2 <br />about revegetation and habitat enhancement efforts for this project. <br /> <br /> Comment 2: <br />Please provide the total area of vegetation (both aquatic emergent, shoreline, and buffer <br />areas) planned for this project and provide a narrative on how vegetation re-establishment <br />and continued management will be approached. <br /> <br /> Response 2: <br />A native lake buffer will be installed and will contain a diverse amount of plants <br />with extensive root systems that will reduce erosion, improve infiltration into the <br />soils, and catch and treat some of the runoff from adjacent areas improving the <br />overall quality of the water entering the lake. The native buffer will also support <br />pollinators by providing a wide range of plants for food and habitat throughout <br />the year. Approximately 1.25 acres will be seeded with a native seed mixture and <br />0.70 acre will be available to plant emergent vegetation. <br /> <br />Soil Preparation <br />Once the site has been graded to finished elevations, all topsoil meeting required <br />organic matter content has been placed (6 inch minimum depth), and all weeds <br />have been removed, the site shall be prepped for seeding. Within one week of <br />seeding operations, the site shall be ripped or chisel plowed to a minimum depth <br />of 12 inches. The soil shall not have a measured compaction greater than 5 <br />pounds per square inch based on Lang or Cone Penetrometer readings. If 10% or <br />more of the readings read higher than 5 pounds, disc harrow or rotovate to reduce <br />compaction to appropriate readings. Once the site compaction requirements are <br />met, the site shall be raked smooth for a uniform and even surface free of lumps, <br />soil, and debris larger than 1-inch-diameter. <br /> <br />Native Plant Establishment <br />Starting from the lake water elevation (normal water elevation is 918.86) up to the <br />top of the disturbed construction limit slopes, the 3:1 slopes will be covered with <br />6 inches of topsoil and seeded with a native grass and forb seed mixture. The <br />native grass species shall be drill seeded at a minimum rate of 10 pounds per acre <br />with 25 pounds of cover crop per acre. The native flower species shall be <br />broadcast at a rate of 4-6 pounds per acre. The seeded areas will either be <br />covered with MnDOT Category 2S erosion control blanket with all natural netting <br />38
