Date: 4/26/2010 An outline of the suggested materials and procedures to be used to install native Wetland Sod Flats and companion wetland seed mixes at the Ramsey East Meandering Commons Park in Ramsey, MN (approximate site size 17,028 sq fi) A. Overview: 1. As per the design, the Ramsey East Meandering Commons Park project includes the use of Eco-Patches in the wetland areas of the site. Eco-patches are produced by Hild and Associates and are essentially pre -grown, vegetated mats that contain either a single species or a blend of wetland species. Prairie Restorations, Inc. (PRI) produces a similar product called Sod Flats which we have been growing and using successfully on projects for over 12 years. Sod Flats are essentially the same size as Eco-patches and can be grown with our without an erosion blanket component. We grow Sod Flats for prairie, woodland and wetland areas. 2. We (PRI) have had discussions with Jim Robin, the landscape architect for the project, regarding the possibility of substituting Sod Flats for the Eco-Patches. Jim is very open to the idea and is interested in learning more about Sod Flats and our thoughts regarding the overall project. 3. As per discussions with Jim Robin before the bidding of the project, he informed us that it is his intention to have the prevegetated mats installed 3 feet on center (O.C.) and not as a continuous "sod." Typically, pre -vegetated mats are installed at this general spacing. He said to bid the installation in this manner (3 feet O.C.) and therefore our bid reflects this spacing. Due to this 3 ft O.0 spacing, we are recommending that a companion wetland seed mix be sown prior to the installation of the prevegetated mats. Over time, the prevegetated mats will spread but not quickly enough to fill in the gaps before invasive weeds would most likely establish themselves. The seeding will help establish native species in these areas more quickly thereby helping to guard against the influx of weeds. Jim Robin agreed with this concept and asked that we submit a cost for the installation of a recommended wetland seed mix. We are recommending a diverse shoreline mix that contains a variety of wetland grasses, sedges and flowers. This diversity will help create interest throughout the growing season. The seed mix is rather expensive (comparatively speaking) but we think worth the investment. In order to help prevent erosion, we are also recommending straw mulching the seeded area as well. Following seeding and straw mulching, the prevegetated mats would be installed 3 feet O.C. in their designated zones. 1
