Waukesha's Housing Policy Improves

The City of Waukesha improved its housing policy last night by allowing residential units in commercial districts, although it would still be conditional upon the Council's approval.  Essentially, this would allow mixed-use buildings with retail or commercial units on the ground floor and residential units on the upper floors.

This was done at the request of a developer interested in developing two parcels.  Kudos to her, but how will this affect the City's regrettable housing mix policy created by the ad hoc committee?  Waukesha has rejected some proposed developments because the housing mix of single-family units to multi-family units were not at the desired 65%-35%.  What makes those mixed-use buildings different?
