Re: Chanhassen West Water Treatment Plant – Planning Commission Submittal
WSB Project No. 1694-72
Project Name: Chanhassen West Water Treatment Plant
Applicant: WSB & Associates, Inc.
Engineer: Greg Johnson, WSB & Associates, Inc.
Owner: City of Chanhassen
Legal Description:
Date Proposed: September 2016
Vicinity Map: Attached, Appendix A
Intended Use and Occupancy: The site will be used for the construction of the West Water Treatment
Plant. The City studied potential locations for the water treatment plant beginning in 2003. At that time,
five sites were evaluated, all in the Galpin Boulevard area due to its proximity to the City’s well field. The
final site was selected based on size, feasibility, availability for purchase, and cost. The water treatment
plant will include one main building; a driveway, loading area, and parking lot; and a tank that will be
almost entirely submerged. The estimated average occupancy is one person. Also located on the
property will be elementary and preschool playgrounds and a bike trail.
Land Use: The planned land use for the property, as outlined in the City’s 2030 Comprehensive Plan, is
Public/Semi-Public.
