HomeMy WebLinkAboutRe: proposal for wetland restoration MEMORANDUM Date: October 30, 2003 To: File From: Janice Waataja, City Planner RE: Prairie Restorations, Inc. Proposal of a Wetland Restoration Project at 3400 Fox Street Scott Van Den Einde from Prairie Restorations, Inc. contacted the City in late October about doing a restoration project at 3400 Fox Street for the McNerney residence. The project involved the area shown on the attached aerial photograph. The proposal was to spray the turf grass to kill it and let it sit over winter. Then in the spring it would be sprayed again to make sure the reed canary grass was eliminated. Following that, the area would be tilled and re-seeded with the vegetation as indicated on the attached plant list. Because the City felt uncomfortable taking a stand on what constituted alteration due to the "wetland" currently being mowed turf, Prairie Restorations was told to contact the Minnehaha Creek Watershed District and the Army Corps of Engineers to determine if permits would be required from them. Following that, Prairie Restorations was to provide that information to the City to determine whether or not a permit would be required from us. Currently, the area indicated on the plan has been sprayed to kill the grass and the MCWD and Army Corps of Engineers is being contacted.

Site Preparation: 1. Define the project area boundaries and stop mowing within. 2. In October 2003 apply Roundup Weathermax� herbicide or equivalent as per manufacturer's directions. Allow a minimum of 10 days before disturbing the vegetation with other procedures. 3. In May 2004, re-spray with Roundup Weathermax�herbicide or equivalent if re-growth of vegetation occurs and when it reaches approximately 10" to 12" in height. 4. Disk or till the soil to a depth of 4". 5. Harrow or rake the soil to create a firm, smooth seedbed. B. Seed and Seeding: l. Seeding dates shall be in the spring or summer before June 30. 2. All grass seed shall be applied with a Tru�� seed drill. 3. All wildflower seed shall be applied by broadcasting. 4. The seed mixes sha11 consist of the following species and amounts: Wetter Areas(�90%) Drier Areas(�10%) Gl'aSSeS lbs./project area Iba./project area Side oats grama(Bouteloua curtipendula)........................................................................................ 1 Fringed brome(Bromus ciliatus).........................................................0.5 Blue joint grass(Calamagrostis canadensis)....................................100 Wet sedges(Carex spP) .......................................................................20 Canada wild rye(Elymus canadensis) ...................................................2 0.5 Switch grass(Panicum virgatum)........................................................0.5 Little bluestem(Schizachyrium scoparium)......................................................................................4 Green bulrush(Scirpus atrovirens) .......................................................3 Wool grass(Scirpus cyperinus)..............................................................1 Note: A wheat or oat cover crop can be sown along with the native grasses at a rate of approximately 251bs.per acre. WheaUoats is an azmual grass species that gem�inates quickly and will reduce the risk of soil erosion on the site.

Tree Planting: 1. An assortment of native woody plants should be added in designated "thickets". The final quantities, species, sizes and locations needs to be discussed. These will ideally be planted immediately following the seeding. The species planted can be selected from the following: Red Maple (Acer rubrum) Gray Dogwood (Cornus foemina) Red Osier pogwood (Cornus sericea) Black Ash (Fraxinus nigra) Eastern Red Cedar (Juniperus virginiana) Tamarack (Larix laricina) Nannyberry (Viburrium lentago) High bush Cranberry(Viburrrum trilobum) D. Plants and Planting: 1. Immediately following the implementation of any erosion control measures, the planting will be further diversified with wildflower and/or grass seedlings. These will be planted individually in appropriate microhabitats throughout, or in designated areas of the project. The plants used will consist primarily of species other than those previously seeded. 2. From the following list a minimum of 30 species will be used. 3. Plant a total of 8,000 seedlings. W ildflowers Sweet flag(Acorus calamus) Fringed loosestrife(Lysimachia ciliata) Meadow gariic(Allium canadense) Monkey flower(Mimulus ringens) Canada anemone(Anemone canadensis) Sensitive fern(Onodea sensibilis) Blue-wood aster(Aster cordifolius) Woodland phlox(Phlox divaricata) Smooth aster(Aster laevis) Prairie phlox(Phlox pilosa) Turtlehead(Chelone glaubra) Mountain mint(Pycnanthemum virginianum) Willow-herb(Epilobium coloratum) Swamp buttercup(Ranunculus hispidus) Jce-pye weed(Eupatorium maculatum) Praine rose(Rosa arkansana) Northern bedstraw(Galium boreale) Green-headed coneflower(R. laciniata) Yellowish gentian(Gentiana alba) Golden ragwort(Senecio aureus) Bottle gentian(Gentiana andrewsii) Balsam ragwort(Senecio paupercaulis) Wild geranium(Geranium maculatum) Cup plant(Silphium perfoliatum) Sneezeweed(Helenium autumnale) Blue-eyed grass(Sisyrinchium campestre) Maximilian's sunflower(Helianthus maximiliani) Bur reed(Sparganium eurycarpum) Wild iris(Iris versicolor) Meadowsweet(Spiraea tonientosa) Meadow blazing star(Liatris ligulistglis) Tall meadow rue(Thalictrum dasycarpum) Tall blazing star(Liatris pycnostachya) Ironweed(Vernonia fasciculata) Turk's cap lily(Lilium michiganense) Culver's root(Veronicashum virginicum) Great blue lobelia(Lobelia siphilitica) Blue marsh violet(Viola cucullata) Grasses Fringed brome(Bromus ciliatus) Tussock sedge(Carex strlcta) Bottlebrush sedge(Car�comosa) Fox sedge(Carex vulpinoidea) Hop sedge(Carex lupulina) Swamp satin grass(Muhlenbergia glomerata) Pointed broom sedge(Carex scoparia) Green buirush(Scirpus atrovirens) Stalk-grain sedge(Carez stipata) Cord grass(Spartina pectinata) E. Management: 1. During the first growing season the project area may need to be mowed to control annual weed development. If a"closed" canopy of weed cover develops, it should be mowed to aid in the growth of the prairie seedlings by reducing competition. Optimum cutting height would be 4" to 6 inches (depending on wildflower species present). Mowings done by PRI will be billed separately unless they are included as part of the installation contract. 2. In years following the first growing season, management services could include site monitoring, burning, mowing, spot spraying, or hand weeding. These services should be contracted separately from the installation contract. Please note that management services are billed on a time and materials basis (a breakdown of cost ingredients would be available prior to contract acceptance). 3. In addition to services contracts, management consulting services are available upon reyuest by calling our Land Management Group at 952-657-2150. F.
