Project status

After years of inactivity, work on Rice Creek Commons since Ramsey County purchased the property in April 2013 has dramatically improved the 427-acre site.


The Joint Development Authority selected Alatus, LLC as the master developer for Rice Creek Commons. Alatus is teaming with Inland Development Partners on commercial development and Tradition Development Corporation on single-family residential development. Alatus will help guide the overall residential and commercial development of the Rice Creek Commons site, an area large enough to fit all of downtown Saint Paul with room to spare. When it is redeveloped, it will be home and workplace to thousands of families.

Ramsey County and the City of Arden Hills are currently preparing the site for development. Construction of surrounding highway infrastructure and site access is currently underway or completed. Internal site construction is expected to be put out for bids in 2018, infrastructure development is expected to begin in 2019, and housing and early commercial construction is anticipated in 2020. .

Remediation efforts

Work to clean and clear the former Twin Cities Army Ammunition Plant (TCAAP) in Arden Hills – formerly the largest contaminated site in Minnesota – has been completed. The Minnesota Pollution Control Agency issued a Certificate of Completion for the soil remediation efforts.

The 427-acre site was cleaned to residential standards (view soil remediation criteria), and 93% of the materials removed from the site were recycled or reused in new roadways there and in other parts of the Twin Cities. This paves the way for the Rice Creek Commons development.

The county has requested the Environmental Protection Agency to officially delist soil at the site from its Superfund list. The U.S. Army will continue to operate the existing groundwater cleanup system for many years to come.
