Tierra Place, 200 South Ashley Street
Ann Arbor, MI
Urban Redevelopment with Sustainable Water Management
The 200 S. Ashley Street Redevelopment Project, in Ann Arbor, MI is an urban brownfield redevelopment project. A seven-story mixed use residential, office and retail space is planned for the site. The building incorporates numerous ‘green’ features, including onsite wastewater treatment and reuse, rainwater harvesting, storage and reuse, green roofs, heat exchangers and environmentally-sound building practices. The integrated design team is aiming for LEED-Platinum certification.
NSI Project Contributions
To minimize water consumption and maximize reuse, NSI integrated wastewater and rainwater harvesting with treatment, reuse and recharge processes. NSI’s design approach includes an onsite wastewater treatment system to produce reuse-quality water for toilet flushing or irrigation. Since this is an urban setting, space is at a high premium. To minimize the treatment system footprint, we placed the primary treatment tank, rainwater harvesting tank, polishing sand filter, mechanical filtration, disinfection and reuse equipment beneath the building.
Reclaimed wastewater will be utilized for toilet flushing. In the event of a reclaimed water shortage, harvested rainwater will be filtered and disinfected as a backup source, with potable water supplied only as a last resort. Excess water generated at the site will be used for aquifer recharge.
Building Cost and Occupancy
PMA Consultants plans to break ground on Tierra Place in late 2008. According to PMA consultants the building will be the greenest building in Ann Arbor. The estimated project cost is $9.6-million, however the cost is equivalent to a conventional project of similar size. PMA plans to the building as a demonstration project of what they can do for their clients. The building will use 65% less energy than a conventional building in Michigan.

Tierra Place will feature retail space on the first two floors for a small-nice grocery store and cafe, similar to Whole Foods. Office space will be reserved for the third, fourth and fifth floors for PMA. Six luxury condos will be built on the sixth, seventh and eighth floors. A roof pavilion will be built for both residents and office tenants. An underground parking garage will provide seven spaces, while bike racks will be built in both the garage and the street sidewalks.
