MnDOT District 7 announces two new managers for program delivery and construction

MANKATO, Minn. — The Minnesota Department of Transportation District 7 recently announced two new additions to its management team. Peter Harff was appointed Assistant District Engineer for Program Delivery and Roger Risser was appointed Assistant District Engineer for Construction. District 7 includes 13 counties in south central and southwestern Minnesota with offices in Mankato and Windom.

Harff started in his new role as ADE for Program Delivery on April 9 and leads the areas of road design, planning, project management, traffic management and hydraulics.

Harff has 18 years of experience at MnDOT where he’s held positions as Program Manager, Design Engineer, Project Management Supervisor, and most recently as the acting Assistant District Engineer for both Program Delivery and Construction. He holds degrees in geology and geo-engineering from the University of Minnesota, and a master’s degree in geology from the U of M. He is a registered Professional Engineer and certified Project Management Professional. Married to Kristine for almost 25 years, they have three children and reside in Mankato.

Effective May 9, Risser will lead the district’s east and west resident construction offices, as well as areas of construction operation including materials and land management.

Risser started his career at the U.S. Army Corps of Engineers in Rock Island, IL, and worked there for 12 years before returning to Minnesota. He then worked as a Construction Engineer for Crow Wing County, a Project Manager for MnDOT District 3, and most recently as the Director of Public Works/County Engineer for Watonwan County. Risser holds a bachelor of science in civil engineering from the U of M and is a registered Professional Engineer. He resides in Mankato.

Harff, Risser and their staff of approximately 130 are responsible for delivering an annual construction program of more than $80 million, on more than 1,300 miles of state and federal highways.

“Peter and Roger have a broad knowledge and experience that will serve MnDOT District 7 well, especially as we face our largest construction year to-date at $130 million,” said Greg Ous, District Engineer. “They value building relationships with employees, communities and our external partners.”
