These are the minutes from the 4/29/13 meeting of the Grand Avenue Authority, featuring an audio link to the presentation from Bill Witte and Bea Hsu of Related.
As previously reported, Related is planning to implement the original first phase (Parcel Q) in two separate steps (Phase IA and Phase IB). Phase IA would be a residential tower with some ground floor retail/restaurant space towards the 2nd/Grand corner of the site.
Phase IB would be a 250 key hotel tower towards 1st street with the possibility of some condos branded by the hotel chain on the upper floor (if the market justifies it). Most of the major retail/restaurant space would be concentrated in Phase IB. Ralphs is still very interested in opening up a second downtown location as part of the Parcel Q development.
The entire residential portion of Phase IA/IB is planned to be 430 units, down from 480 in the original plan. That number could shrink more if the 50 planned condo units in the hotel tower don't pan out.
Wasn't able to glean any specifics on the heights of the buildings, although the residential tower will definitely be taller than the under construction Parcel M.
Considering this meeting was over one month ago, I'm not exactly sure what decisions were made. Minutes are only posted up to May 6th. It does sound like the Grand Avenue Authority has some big concerns with the new plans, particularly in regards to the pedestrian central plaza. Huizar and Molina both expressed concern that the central plaza was going to be oriented away from public view, citing California Plaza as an example.
Bill Witte stated that March 2015 is the likely groundbreaking date.
One other interesting thing mentioned by Huizar was that Macy's Plaza might be "demolished." Not sure if he meant that literally or just that there would be a drastic remodel.
