Vegetation Management Plan
Vegetation Management Plan
Preserve at Rice Lake,
Chanhassen, Minnesota
This plan applies to the proposed wetland buffer areas in the Preserve at Rice Lake.
I.Site Preparation
A.If the wetland buffer area remains undisturbed and natural vegetation is
thriving, those areas shall remain undisturbed. They will be protected during
site construction with silt fence or other protective fence such as orange snow
fence.
B.Site Preparation shall consist of the following for proposed wetland buffer areas
that have are not undisturbed:
i.Preparation of the seedbed in a manner that prepares the project
site for seed and tree planting. After final grading has been
completed, the site will be cultivated with a light disking and
dragging.
ii.Install seed according to specifications after seedbed is prepared.
II.Seed Specifications
A.Use native grass seed: fresh, clean, dry new-crop seed.
B.Seed mixes shall be blended by the Contractor using the specified species and
ratios. Seed mix species and ratios shall be guaranteed by the contractor to be
true to specifications as required. The contractor shall supply and plant native
seed as pure live seed (PLS). See planting plan for planting schedule. Contractor
shall provide tags to the City. All seed shall have the proper stratification and/or
scarification to break dormancy for spring planting. No treatment required for
seed used in summer and fall plantings.
III.Tree Specifications
A.Use tree stock from local genotype that is native-grown within 150 miles of the
City of Chanhassen.
IV.Seeding and Planting Protocol (includes Wetland and Upland Buffer Areas)
A.Dormant seeding shall occur between mid October and mid November.
Seed may be hand-broadcast or planted using a properly calibrated seed drill
over the site at the rates and with the species mix identified. After seeding, the
site will be dragged and cultipacked to ensure good seed to soil contact in
accordance with the seed supplier’s recommendations.
V.Cover Crop
A.For a fall planting, use a cover crop of winter wheat at a rate of 56 pounds per
acre.
VI.Maintenance
A.Year One (first full growing season after original seeding/planting): Mow, using a
flail type mower, to a height of 5 to 8 inches, just over the height of the
emerging native plants before weeds go to seed. Assume three mowings in the
first season.
B.Year Two through Five: Spot mow and spray invasive weed species as necessary.
The wetland buffer areas will be seeded with the 36-211 Woodland Edge South and West mix
according to Minnesota State Seed Mixes (see below).
The Wetland buffer areas will be located within outlots that are to be City owned. Wetland
Buffer Signs will be posted at the rear lot corners on the single family lots that are adjacent to
the wetland buffer areas.
