[ARCHIVED] Iowa's Roadside Mowing Laws - No Mowing Prior to July 15th

Iowa Mowing Laws

IRVM reminds citizens to be aware Iowa's roadside mowing laws. Iowa Code 314.17 (PDF) prohibits mowing of roadside vegetation on the rights-of-way or medians on any primary highway or secondary road prior to July 15th. 

What You Can Do

  • Before July 15, only mow roadsides as needed for safety, spot weed control, and removing competition for native prairie seedlings.
  • Delay haying and mowing for brush control until after July 15.
  • Delay mowing until after July 15 to promote game bird and songbird nesting habitat and reduce soil erosion from spring rains.
  • To best help monarch butterflies, delay blanket mowing until after Oct. 1.
  • If you wish to harvest hay on state roadsides, contact the Iowa DOT maintenance garage or contact listed on the Iowa DOT website
  • Along county roadsides, contact your county engineer or county roadside manager to learn more about Integrated Roadside Vegetation Management, which uses selective mowing and Iowa’s native plants in county roadsides.
