CMK/Lend Lease Propose Zoning Change to Build 2,700 Residential Units Along Chicago River

More news is emerging on the CMK/Lend Lease joint venture and their intentions to develop the current vacant land Harrison and the Chicago River (via crains):

A development group that has been gobbling up South Loop land wants to build five towers with nearly 2,700 residential units on one site it controls just four blocks south of the Willis Tower. 

The joint venture between Chicago developer CMK and Australian construction company Lend Lease Group has submitted plans with the city for the 7.3-acre riverside parcel between Harrison Street and the River City condominium complex. The largest building, on the north end of the site, would rise 47 stories and include 626 units.

As you may know, CMK and Lend Lease also acquired vacant land just south of here as well.  The article says they joint venture is currently drawing up plans for these lots as well.

Residents are also starting to get these letters in the mail, which announced the proposed zoning change:

That's a lot of units!  While urban density proponents are probably gitty, many other neighbors are reasonably concerned.  Our neighborhood continues to get more and more crowded.  Generally speaking we are excited about these developments, but the city needs to make sure infrastructure improvements are moving at a similar clip (such as the proposed Wells/Wentworth connector).
