New Buildings Continue Pushing West, Surrounding Union Park

Union Park, once known for music festivals and immigration marches, is getting yet another tall neighbor.  West suburban Naperville developer Marquette wants to put up a residential high rise right across the street.

The proposal is for a 210-unit apartment building at 140 North Ashland Avenue, on the west side of Union Park, immediately south of the CTA’s Ashland Station, serving the Green and Pink L lines. Marquette is also putting up two buildings on the east side of Union Park, at 1400 and 1454 West Randolph Street.

The new project will replace a three-story building currently on the site.  It will, however, preserve and extend the existing six-story building immediately to the south on the northwest corner of Ashland and Maypole Avenues.

Although paperwork filed with the city by the developer lists March 18 for a Plan Commission hearing, it is not currently on the agenda for that meeting.
