ATTACHMENT 3 WORKPLAN FOR MISSISSIPPI WEST RESTORATION Mississippi West Regional Park and City of Ramsey Stormwater Basin Restoration The southeast portion of Mississippi West Regional Park contains two parcels totaling approximately 20 acres that border the Mississippi River and is a site that has great potential to be restored to native oak savanna/native prairie. It currently comprises of a 1-acre stormwater basin that treats runoff from an adjacent residential development, a3-acre mowed area, a 13-acre old field, and a 4-acre riverbank area. The proposed body of work will be accomplished by a partnership between the following organizations: City of Ramsey, Anoka County Parks, Anoka Conservation District, and Great River Greening, MN Board of Water and Soil Resources and Metro Conservation Corridors through LCCMR. Tasks will include: 1) prepare the site for seeding and planting, 2) control invasive exotic species so as to release existing native vegetation, 4) plant with native seeds and plugs of local ecotype origin and 3) utilizing removed red cedars to create revetments that stabilize eroding riverbanks on the Mississippi River. Site Preparation Site preparation around the pond will involve stump grinding of existing tree stumps that surround the perimeter of the pond, as well as spot herbicide treatments (spring/summer, 2009). Site preparation of the mowed area will involve prescribed burning and broadcast herbicide applications to kill the existing turf grass (spring/summer, 2009). Site preparation of the 13-acre old field will consist of removing existing woody invasives (primarily eastern redcedar, with some boxelder, cottonwood, Siberian elm, green ash, common buckthorn and Tartarian honeysuckle), grubbing or grinding out the stumps, and then performing a prescribed burn in the fall of 2009), with some spot herbicide treatments will be applied as necessary. Site preparation of the Riverbank area (between trail and river) will consist of removing overabundant grape vines by cutting them near ground level, and then treating the cut stumps with appropriate herbicide. Planting/Seeding Planting and seeding will commence upon successful site preparation. Planting in the pond area will consist of either light hand seeding into existing vegetation or nothing at all, since diversity is fairly good in this area. The old field will be seeded with a drill seeder in the fall of 2009 following the prescribed burn. The mowed area will be planted and seeded in combination, to affect a prairie restoration with zones of shrub and forb (plug) plantings to create visual interest Great River Greening 14
