DATE:
SUBJECT:
Interim Use Permit Application - Necon Farm Properties and Jacob
Wert - 8601 Great Plains Boulevard
The applicant is requesting an interim use permit to import approximately 43,000
cubic yards of material. The 7.95 acre site is bordered by Old Trunk Highway
101 to the north and west, Trunk Highway 101 to the East and Lake Susan Drive
to the south.
There is an existing house, two accessory structures, and a gravel drive on the
site; all of which will remain at the completion of site grading. Approximately 50
percent of the site is farmed or grassland. The site will be left in a condition that
will be used for crops in the short term and facilitate development in the future.
The site currently has two drainage areas. Approximately 90 percent of the site
drains through a 48" culvert installed by the MN Department of Transportation
during the construction of Trunk Highway 101. The remaining 10 percent of the
drainage is directed towards the northeast property line. The proposed grading
plan does not change the drainage areas. Drainage calculations were not provided
or required with this submittal. The reason for not requiring drainage calculations
is because the drainage areas and impervious surface is unchanged.
Most of the significant trees on the site will be saved. The black walnut woods
will remain after grading completion. Approximately twelve trees will be
removed near the middle of the site. The trees that will be removed are primarily
box elder and poplar. Some trees near the US West Telephone property were not
shown on the plans. These trees will need to be shown on the existing conditions
plan and the proposed grading plan to determine which trees will be saved. The
trees near the US West Telephone building should be preserved for building
screemng.
Most of the fill is proposed near the center of the property. Up to 10 feet of fill
will be placed in some areas. No fill will be placed near the buildings or in the
black walnut woods. A temporary stock pile of black dirt is shown near the
northeast comer of the site. This area will need to be graded back to existing
conditions upon completion.
The City of Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.
