DM&E is authorized to pursue two route alternatives in the Mankato area. The Federal Railroad Administration (FRA) reported the following statistics and comments (in quotes) in its January 2007 Impacts Summary:

1. Bypass south of Mankato – 13.3 miles

Impacted area: 322.4 acres disturbed

Surface Water: Cross 10 streams crossed, including Blue Earth River.

Wildlife: Habitat loss, displacement and mortality. Disturbance from noise and human activity.
• Aquatic and Fisheries: “Increased TSS [total suspended solids] in 10 streams, including the Blue Earth River. Alteration and loss of habitat. Changes in hydrology and water quality.”

Recreation: Proposed route crosses bike trails (Red Jacket Trail and the South Route multi-use trail) six times.

“Delays at crossings. Increased safety risks to trail users and visitors to Mt. Kato ski area.
Potential decrease in overall quality of outdoor experience.”

Aesthetics: “Ground disturbance and the presence of construction machinery would disrupt scenic view. Breakup of natural setting. Permanent change of rural landscape with addition of rail line and railroad facilities.”
