Survey & Utility Flag Color Code Chart

Most “flag color meaning” searches are talking about utility locate colors. Many crews follow the APWA color code, but always follow local rules and what your utility locator/surveyor tells you.

Common utility/survey marking colors (APWA):

- White: Proposed excavation
- Pink: Temporary survey markings
- Red: Electric power lines/cables
- Yellow: Gas, oil, steam
- Orange: Communications (phone, cable TV, fiber)
- Blue: Potable water
- Green: Sewer and drain lines
- Purple: Reclaimed water, irrigation, slurry lines

Property survey flag colors
Surveyors may use different colors for points, corners, and notes. There is no single national “property survey flag color” for every job. If the mark affects digging, use the utility color chart above and call 811 before you dig.

What color are property line flags?
There is no one official “property line flag color.” Property corners are usually set with permanent markers (like an iron pin). Flags are used to make the area visible, not to legally set the line. If you need the exact line, hire a licensed surveyor.

Red marking flags meaning
Red usually means electric lines or cables (APWA). Treat red marks as “high risk” and keep digging away until the line is verified.

Understanding Marking Flags and Their Uses

What Are Marking Flags?

Marking flags are small, brightly colored flags used primarily for a variety of outdoor applications. These flags are essential tools for surveyors, landscapers, and contractors, as they help mark boundaries, utility lines, and other important locations. Because they are designed to stand out, marking flags ensure that they are visible even from a distance, making them an effective solution for project visibility and safety.

Different Types of Marking Flags

There are several types of marking flags, including stake flags and landscape flags. Stake flags typically come with a sharp point that allows them to be easily pushed into the ground, creating a more secure hold. On the other hand, landscape flags are often used for marking plants or garden layouts. They can be made from durable materials to withstand outdoor conditions, ensuring longevity and reliability.

Why Use Marking Flags?

Marking flags offer numerous benefits, making them a smart choice for your next project. For one, they improve safety by clearly marking hazardous areas. Additionally, they help everyone involved in a project know exactly where boundaries and utilities are located. So, when you choose marking flags, you not only enhance your project's organization, but you also protect your team from potential accidents.

Temporary survey markings (what they’re used for)

Temporary survey markings help crews see key points fast: corners, offsets, grade stakes, or notes about a site. They are meant to be seen, then removed later.

I am in charge of 8 cemeteries and these flags are perfect for showing the grave diggers where to dig.

We have had issues in the past with folks coming to mow our lawn and inadvertently mowing over flowers and things we didn't want mowed, so I got these flags to mark those spots. They are a great value for the money and do the job.
