Before Contacting Iowa One Call
When you contact Iowa One Call with a locate request, a series of questions will be asked.
- What is your name, address and phone number?
- What type of work will you be doing? (i.e. planting a tree, installation of fence)
- What is the dig location’s address, city, county and nearest intersecting street?
- At the dig location, where will you be digging? (i.e. east side of house, within 5 ft radius of white stake.)
- When will you be digging? (i.e. 3 days, next week)
For more information, check out our guide for Homeowners below.
Paint or Flag Color Indicators
Underground facilities will be marked according to the APWA Color Code. It is extremely helpful for you to outline your proposed excavation site in white paint or with white flags to reduce any confusion as to where the proposed excavation will occur.
Red – Electric Power Lines, Cables, Conduit and Lighting Cables
Yellow – Gas, Oil, Steam, Petroleum or Gaseous Materials
Orange – Communication, Alarm or Signal Lines, Cables or Conduit
Blue – Water, Irrigation and Slurry Lines
Green – Sewers and Drain Lines
Pink – Temporary Survey Markings
White – Proposed Excavation
Purple – Reclaimed Water

Things To Remember
You must contact Iowa One Call at least 48 hours (not including weekends and holidays) in advance of your plans to excavate.
A ticket is valid for 20 calendar days from the time of the call.
ALWAYS check yard markings and Iowa One Call Positive Response ticket status before beginning excavation.
What Does NOT Get Marked
Only the buried facilities registered with Iowa One Call will be located and marked. Private facilities will not be marked for locates. These can include LP gas lines, sprinkler systems, gas grill lines, or more.
Homeowners may call private locating companies to have their private facilities marked.
Paint and flag markings are approximate. The tolerance zone is 18″ on either side of the markings. You should hand dig with caution in the tolerance zone to expose the facility.
Best Practices are derived from existing multi-industry, governmental and public practices that are determined to be “best” in enhancing safety and through rigorous review and evaluation processes developed by the CGA.
