northeast of the wetland. Other features to investigate include pervious pavement systems,
cisterns, biofiltration trenches, preservation or re-establishment of vegetation, etc.

must be obtained prior to construction.
14. The 51-inch and 45-inch oaks located near the northwest and southeast comers of the
building shall be protected by fencing throughout construction.
15. The site plan must show the dimensions of the lots.
16. The northern access must be revised so that the maximum width does not exceed 36 feet.
17. An encroachment agreement is required for the portion of the parking area that lies within the
public right-of-way.
18. If feasible, the runoff from the cold storage area access should be conveyed to the existing
storm sewer.
19. Revised drainage calculations and storm sewer sizing must be submitted to ensure that the
existing downstream infrastructure can accommodate the proposed runoff.

drainage and utility easement.
21. The proposed top and bottom of wall elevations must be shown.
22. The drainage and utility easement over the abandoned portion of the sanitary sewer must be
vacated.
23. The existing drainage and utility easements and abandoned utilities must be labeled on the
plan sheet.
24. The utility plan must include a note regarding the connection to the existing storm sewer."
B. "Conditional use permit for outdoor storage, subject to the following condition:
1. The proposed development must comply with the approved site plan, plans prepared by
Oertel Architects and the City of Chanhassen, dated 12/05/08."
Construction plans must address the conditions of approval. Detailed occupancy related
requirements will be addressed when complete building plans are submitted. The owner and/or
their representative shall meet with the Inspections Division as soon as possible to discuss plan
review and permit procedures. All erosion control and tree protection measures shall be installed
and inspected prior to beginning construction activity. An encroachment agreement is required
for the portion of the parking area that lies within the public right-of-way.
