Hwy 23 Living Snow Fence

Marshall

Project summary

Install a living snow fence at the reduced conflict intersection of Hwy 23 and Lyon Co Rd 7 in Marshall. A living snow fence is made up of trees, shrubs, native grasses and/or wildflowers to trap snow as it blows across fields, piling it up before it reaches a roadway.

The living snow fence at Highway 23 and Lyon County Road 7 is more than 1,400 feet in length and fifty feet wide, and follows the northwest corner of the reduced conflict intersection. The planting of deciduous trees and shrubs is ten feet across with twenty-foot prairie buffers on either side. The plants are native to Minnesota in order to withstand harsh conditions and include:

  • 220 American plum trees
  • 102 fragrant sumac
  • 252 silver buffaloberry
  • 106 gray dogwood
  • 81 glossy black chokeberry

Project updates

  • Soil prepared and geotextile weed barrier fabric installed
  • Root-ball stock planted: American plum trees, fragrant sumac, gray dogwood, glossy black chokeberry
