Dear Mr. Rosenlund:
This letter is to formally notify you that on January 22,2007, the City Council
adopted the following motion:
"The City Council approves the preliminary plat for Planning Case 07-03 for Fox Hill
Subdivision for 3 lots with variances to allow a private street as shown on the plans
dated received December 1, 2006, subject to the following conditions:
1. A minimum of two 2Yz-inch deciduous, overstory trees shall be required in the
front yard of each lot.
2. No more than one-third of the required trees may be from anyone species.
3. Tree preservation fence shall be installed at the edge of the grading limits
around all trees proposed to be preserved prior to any grading.
4. Any trees proposed for preservation that are lost due to grading and
construction activities will be replaced at a rate of 2:1 diameter inches.
5. The Storm Water Pollution Prevention Plan (SWPPP) shall be provided to the
City so it can be reviewed by the Carver Soil and Water Conservation District.
6. The plans shall be revised to incorporate Chanhassen' s standard details for
erosion and sediment control, including 5300, 5301, 5302A and 5302D.
7. In order to ensure that the proposed infiltration area functions properly, the
contractor shall minimize the number of equipment trips across this part of the
site. Additionally, the lightest equipment appropriate for the job shall be used.
Once the infiltration area is graded, the easement area shall be fenced off so
no further compaction occurs. The applicant may want to consider planting
native shrubs, grasses and wildflowers within the infiltration area instead of
sod to promote volume reduction through infiltration and evapotranspiration.
8. A stable emergency overflow (EO F) for the infiltration area shall be provided.
The EOF could consist of riprap and geotextile fabric or a turf re-enforcement
mat (a permanent erosion control blanket). A typical detail shall be included
in the plan.
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.

must have a 2% minimum slope. Also, the swales in the northwest comer of the house of Lot

storm sewer lines. The actual elevations of existing utilities shall be determined.
28. Install cleanout for the sewer service for Lot 2 due to length.
29. Each new lot is subject to the sanitary sewer and water hookup charges. The 2006 trunk
hookup charge is $1,669 for sanitary sewer and $4,485 for watermain. Sanitary sewer and

permit issuance. All of these charges are based on the number of SAC units assigned by the
Met Council and are due at the time of building permit issuance.

between the easement and the proposed utilities.
31. A lO-foot drainage and utility easement will be required for the front of Lots 2 and 3.
