SUBJECT PROPERTY
Lake Ann
North of West 78th Street and west of Lake Ann Park.
This site was formally occupied by Natural Green a Landscape contracting business. In 9189 the business moved and the site was restored. With the upgrade of TH 5 and the frontage road
the excess right of way was acquired by Southwest Transit as a potential Park and Ride. Development of the site is challenging because of the topography, wetlands, shoreland district,
access to sewer and aces off of West 78th.
Over the years Southwest Transit chose not to utilize the site and put in on the market. There has been numerous proposals on the site but with the site constraints no project has
advanced. To date this project was best suited for the site, the developer has made a number of compromises and the staff supported two variances.
The request consists of multiple applications to facilitate the construction of a continuing care retirement facility (The Moments of Chanhassen). The request includes a rezoning from
Rural Residential District to High Density Residential District, site plan approval with variances for the construction of a continuing care retirement facility.
