Arlington had a dying retail corridor surrounded by single-family neighborhoods. They did highly targeted approval-only incentive zoning within a quarter mile of Metro stations and preserved the neighborhoods (you can look at some of the old plans online). It also seems to have had a heavy adverse impact on previously existing retail, though the effects of construction disruption are difficult to separate from the general trend toward suburban malls at the time.

Personally I think we in the Puget Sound area are not using the same approach at all, though that doesn’t mean our methods won’t work.
