MLive's Ryan Stanton covered this story: Ann Arbor council delays decision on Nixon Farms 472 unit housing development

In a 6-5 vote, the council decided to postpone the issue to the council's Dec. 21 meeting, despite the developer arguing that another delay would be too much of a financial hardship for the development.
[Councilmember Sumi] Kailasapathy questioned the results of a Nixon/Green/Dhu Varren intersection study performed for the city by a consultant.  The study by Opus International Consultants Inc. found on average a morning peak wait time or rush hour delay of 193 seconds for southbound Nixon Road traffic, and an afternoon peak wait time of 161 seconds for northbound Nixon Road traffic. With a roundabout, with projected traffic levels in 2035, those delays are anticipated to be reduced to 24 seconds and 26 seconds, respectively. Kailasapathy said the actual wait times at the intersection right now are more like 30 minutes, not three minutes. "I live through this every single day," she said, adding the numbers in the study don't make sense to her.
