721 N. Main is a 5.26-acre site on the north side of downtown. The property currently used by the City Public Services Department for municipal parking. There are two warehouse buildings on the site that are no longer in use. The site is currently zoned PL, Public Land. The site is within the floodway and floodplain. The site has been remediated and currently meets standards for unrestricted residential use; however, the FEMA grant used to finance the environmental clean-up placed additional use restrictions on the site limiting the future development.
This property is a key link in The Treeline Allen Creek Urban Trail master plan. The preliminary concepts are design to accommodate all proposed options for the Treeline route at this location. The recommended action is to split the parcel to create a smaller development site along Summit(123 W. Summit) which is outside of the floodplain and leave the majority of 721 N. Main intact for a future use to be determined by the city in accordance with the vision of the Treeline master plan.
Key adjacent uses include the railroad immediately to the west and the Ann Arbor Community Center and the Ann Arbor Distillery to the south. The potential recommended zoning for the site is C1, Local Business District. This is consistent with the current zoning along Summit St. C1 zoning allows for a maximum of 3 stories and a Floor Area Ratio (FAR) of 100% by right.There are no affordable housing bonuses for the C1 zoning. From a financial perspective,721 N. Main has multiple site constraints that reduce the rental subsidy options. This site would not be eligible for Low Income Housing Tax Credit (LIHTC)development. The concepts consider different housing typologies to maximize the total unit count within the current site constraints and zoning requirements. Resident and visitor parking are provided on-site for all options. This site does not accommodate future trailhead parking for the Treeline.
The city is subsequently working on a downtown parking analysis and downtown housing market study. The results of those studies will be integrated with community feedback in December 2020 report out.
