Greetings, @Keithl93! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day and staying safe out there. The flags you have were left over from the utility company marking where their lines are (gas, water, electric) so we didn't hit any of those when burying the new cable. If the bury is fully complete you can discard them. Please let us know if you have any further questions.
