Overview of the UMore Park project

The University of Minnesota has long-term plans to develop the property it owns in Rosemount and Empire at the former site of a smokeless gunpowder plant, Gopher Ordinance Works. The facility was built and operated during World War II until the land was bought in 1947 and 1948 from the federal government by the university. The 4,366-acre property, named "UMore Park", has been historically used for agricultural research, university projects, and tenant agricultural, industrial, and commercial activities. 

In 2015, the University's Board of Regents approved the original 2008 plan to be revised to a market-based approach for development in UMore Park. This development is expected to occur in stages spread across several decades. Visit the University's UMore Park website for information relating to the property and online information repository.

The City will post related documents and notices on this webpage. Users can sign up for emails to notify them when the content of the webpage is updated.

UMore Study Area AUAR

The Alternative Urban Area Wide Review (AUAR) consists of a hypothetical development scenario, an inventory of environmental and cultural resources, an assessment of the cumulative impacts that the development scenario may have on these resources as well as public infrastructure services. It contains a set of mitigation measures intended to address the cumulative impacts resulting from a sequence of related development projects as opposed to an Environmental Assessment Worksheet (EAW) or Environmental Impact Statement (EIS), which simply looks at a single project's impacts and does not attempt to outline mitigation initiatives. This review does not include any comments regarding building layout, uses, architecture, etc. The AUAR must be updated every five years. 

The City of Rosemount has prepared an Alternative Urban Areawide Review (AUAR) for the UMore Study Area. The study area is approximately 4,900 acres and is located in portions of the City of Rosemount and the City of Empire, Dakota County. The AUAR reviews potential environmental impacts associated with three development scenarios, along with a no-build scenario. The scenarios include a variety of possible residential, commercial, and light industrial development that could occur within 5 to 50 or more years. Please share any feedback you may have on the UMore AUAR to Julia Hogan, Planner. In addition to the current update, the original AUAR and subsequent updates are provided below.

Remedial Investigation of UMore Park East

A Remedial Investigation was conducted to collect information needed to identify and assess potential risks to human health and the environment associated with historical uses of the property. The UMore Park East site includes the industrial section of the former Gopher Ordinance Works (GOW), a smokeless gunpowder production facility owned, constructed and operated by the federal government during World War II. Since its acquisition by the University in 1947 and 1948, the site has been used for University agricultural and other research projects and tenant agricultural and commercial activities.

The Remedial Investigation report and other environmental reports regarding the site are available for public review between the hours of 9:00 a.m. and 3:00 p.m., Monday through Friday, at the Information Repository established by the University, which is located at the UMore Park Administration Building, 1605 160th Street W, Rosemount, MN 55068, and on the UMore Park website.

Public Health Assessment

The Minnesota Department of Public Health wrote a Public Health Assessment for the former Gopher Ordnance Works site, at the request of the MPCA. The report provides a review of the environmental data and relevant site history from a large number of documents and offers recommendations intended to protect public health. The report discusses soil and groundwater contamination, gaps in existing data, the potential for people to be exposed to contaminants, and potential impacts on drinking water resources due to planned future development.
