Flags placed in HOA common areas usually mark underground utilities, irrigation, planned excavation, landscaping work, or temporary survey locations. Utility providers may also enter easement areas to perform work without separate HOA authorization.
Common reasons flags are placed
- Marking underground utility lines.
- Identifying irrigation or sprinkler locations.
- Preparing for excavation or construction work.
- Marking landscaping treatment areas.
- Temporary survey work.
Common flag colors
- Red: electric power lines, conduit, or lighting cables.
- Yellow: gas, oil, steam, petroleum, or other gaseous materials.
- Orange: communications, cable TV, alarm, or signal lines.
- Blue: water, irrigation, or slurry lines.
- Green: sewer or drain lines.
- Pink: temporary survey markings.
- White: proposed excavation.
Utility-company flags are often labeled with the provider performing the work.
Note: The HOA may not always receive advance notice of utility work performed within an easement.
