​Site Description and History​

123 W Summit is a 5.26-acre site on the north side of downtown. The property is currently used by the City Public Services Department. There are warehouse buildings on the site that are no longer in use. The site is currently zoned PL, Public Land. Most of the site is within the floodway and floodplain. The City received a FEMA hazard mitigation grant to remove a struct​ure on the site and the FEMA grant restricts the future use in perpetuity to open space for the conservation of natural floodplain functions. 

As part of the ​​​analysis, it was determined that t​he northwest corner of the site that abuts W. Summit Street was the only portion of the site that was not in the floodway or floodplain and is suitable for affordable housing development. Therefore, a .33 acre parcel in the northwest corner was split from the 5.26 acre parcel known as 721 N. Main for the purpose of developing affordable housing.   

Key adjacent uses include the railroad immediately to the west and the Ann Arbor Community Center and the Ann Arbor Distillery to the south. 

From a financial perspective, the site has multiple constraints that reduce the traditional development subsidy options due to its small size and proximity to the railroad and Main St (related to noise).  However, this site may be developed using local and philanthropic funds. The concepts in the Feasibility Analysis consider different housing typologies to maximize the total unit count within the current site constraints and zoning options. Resident and visitor parking are provided on-site for all options. 

The City is considering the following objectives for redevelopment:

  • Maximize affordable housing units below 60% AMI
  • Maximize market rate housing units
  • Develop a mix of housing unit types and prices
  • Engage the Treeline Trail
  • Fit in with existing adjacent building heights and scales
  • Provide parking on site
  • Maintain some City ownership/control
  • Fit in with existing adjacent building heights and scales
  • Sell the property and use proceeds for affordable housing on another city-owned property
