Dear Mr. Rick:
This letter is to formally notify you that on August 22, 2005, the City Council
adopted the following motion:
The City Council approves the preliminary plat for Planning Case 05-25 for
Minnewashta Creek Hill for 3 lots and a variance to run a private street as shown
on the plans received July 20, 2005, subject to the following conditions:
1. Environmental Resources Specialist Conditions:
a. Tree preservation fencing shall be installed at the edge of grading
limits prior to any construction. Fencing shall be maintained until
constniction is completed.
b. Any preserved trees removed will be replaced at a rate of 2: 1 diameter
inches.
2. Park and Recreation Conditions:
a. In lieu of any land dedication, full park fees shall be collected at the
time of platting. With the one existing home, the total park fee for
Minnewashta Creek Hill will be $8,000.
b. Additional trail construction is not required as a part of this project;
however during demolition and construction, the existing pedestrian
trail shall be protected and remain open. No construction equipment
shall be parked on or use the trail as a staging area during
construction. In addition, all match points encountered on the trail for
demolition and/or construction shall be professionally constructed.
3. Detailed grading, drainage, tree removal and erosion control plans must be
submitted with the building permit for each lot.
4. The driveway grade must be adjusted so that runoff from the driveway will
sheet drain to the east. The grades east of the proposed private drive must
be adjusted to provide a drainage swale along the east side of the driveway
to the proposed catch basin.
5. Any proposed retaining wall over four feet high requires a building permit
and must be designed by a Professional Engineer registered in the State of
Minnesota.
The City 01 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.

areas, as a result of construction, shall be seeded and mulched or sodded immediately
after grading to minimize erosion.
