Call Iowa One Call Before You Dig

If your spring plans include yard work, remember Iowa One Call before you dig. Whether it’s a large or small project, the law requires you contact Iowa One Call at least 48 hours prior to excavating. 

  • Projects include (but are not limited to):
  • Installing a fence
  • Planting or removing trees or shrubs 
  • Building a patio, addition, deck, garage, outdoor shed or any similar structure 
  • Putting in a new driveway or sidewalk 
  • Installing a septic system or water drainage system
  • Terracing or landscaping

It is helpful for any proposed excavation site to be outlined in white paint or white flags by the homeowner or contractor. 

Please note the 48 hour timeline applies during weekday business hours, not weekends or holidays. 

Iowa One Call will dispatch locators to mark all buried utility lines on the property so you can safely dig and prevent a potentially hazardous situation. 

Requests can be made 24 hours a day, 365 days a year at 811 or 1-800-292-8989 or online at
