The colored flags in a yard typically indicate where underground utilities are located. These flags act as a warning, to alert anyone digging or excavating in the area of the presence of utilities such as electrical, phone, and water lines.
Different colors of flags indicate different types of utilities; for example, red flags typically represent electrical lines, blue represents water lines, yellow represents gas lines, and green indicates sewer lines or storm drains.
The flags often give a rough indication of the depth of the utility lines as well. The depth of flags is typically correspond to the depth of the utility line, with higher flags indicating a shallower depth, and lower flags indicating a greater depth.
It is important for anyone excavating in an area to be aware of these flags and the utility lines below, and to call 811 to have the lines located accurately and marked if necessary, before any excavation is done.
This will ensure both the safety and accuracy of the project.

What are the colors of utility flags?
The colors of utility flags vary depending on their purpose. For general location, a red or orange and white checkered flag could be used, while international distress codes are identified by a bright orange and white flag, with a solid black square in the center to indicated a “mayday” call.
Other utility flags consist of solid, bright colors like red, yellow, green, and blue, with white, black, and purple also used as accent colors. Some safety and warning flags are printed with a series of horizontal stripes in alternating colors, often red, orange, yellow, and blue.
Each country has its own set of standard utility flags, so be sure to check the local regulations before selecting the appropriate flag for your task.

What color flags do surveyors use?
Surveyors typically use several colors of flags in order to mark out survey sites or objects precisely. The colors used are generally dictated by local surveying laws and can vary from region to region.
Typically, colors such as white, green, yellow, and red are used for a variety of reasons. White is the most often used color, as it is the most visible against the background. White flags are used to mark points that need to be surveyed, boundaries on a site, or the location of underground utilities.
Green flags are typically used to mark the locations of points that have already been surveyed, and yellow flags are used to depict areas of caution. These flags can include aerial surveys, waterway marker flags, prohibitory flags, and warning flags.
Red flags are usually used to mark areas where dangerous conditions exist such as construction sites, gas lines, or power lines. Surveyors also sometimes use blue flags to mark aquatic boundaries and boundary corners.
What utility uses red flags?
Red flags have historically been used by a wide variety of utilities and institutions, from the military to law enforcement, banking, finance, and medical institutions. In some cases, they may serve as a warning of imminent danger, while in other cases they may be used as a form of identification.
The most common use of red flags is by the military. They are regularly used in the form of a signal flag or flagpole in order to communicate the various statuses of operations. For example, a red flag may indicate a state of alert or a situation that requires special attention.
Similarly, it is also used to signal the end of a battle or exercise.
Law enforcement agencies also use red flags as warning signs that a crime has been committed or is to be avoided. For example, a red flag may be flown at the scene of a crime to signal passersby that a dangerous situation exists.
In the banking and finance sector, red flags are used to denote potential fraud or other suspicious activity. They are often used to notify financial institutions of potential threats to the security of their finances or the safety of their customers.
Finally, red flags can also be found in the medical community, where they are used to indicate potential medical conditions that require further investigation. For example, a red flag may be used to signal a high fever or the presence of an infection or virus.
What color are survey markers?
Survey markers are normally colored brightly so they can be seen easily from a distance. The most common colors for survey markers are pink, orange, and hot pink. Depending on the survey department, the colors might differ.
Other colors used to create survey markers are red, purple, blue, green, yellow, white, and black. Survey markers are often made with a lead core and aluminum foil and sprayed or painted in a bright color.
The aluminum foil provides extra visibility from a distance and ensures that the marker can be seen from aircraft.
What is the most common Colour of survey pegs?
The most common color of survey pegs is fluorescent orange. This color is used because it is highly visible in most environments, which makes it easier to spot and identify the survey pegs being used.
The fluorescent orange color stands out against most backdrops, making it easily visible from a distance and easier to follow survey lines from one peg to another. It is also one of the few bright colors that is visible to surveyors even in low-light conditions.
In addition, fluorescent orange is a color that does not reflect off of metal or other bright surfaces, which makes it ideal for surveying metal structures and structures made of other reflective material.
What do property survey pins look like?
Property survey pins, also known as corner stakes or survey monuments, are typically metal poles, pipes, or markers placed in the ground at each corner of the lot. They are typically planted at a depth of 2-3 feet and are visible from the surface.
They are used to identify the boundaries of a parcel or lot, and the exact locations of the corners and angles of the lot boundaries. They may be painted, but usually have either a numbered cap, a flag or a cone-shaped object near the surface.
The pins usually come in a variety of sizes and colors, with orange and blaze being the most common colors. On larger parcels, a reference post may be placed, which is a more obvious marker, typically a 3-4 foot tall post similar to a fence post.
Survey monuments can also come in the form of iron rods, survey caps, or brass, iron or aluminum plugs. These items are intended to remain in the ground for an indefinite period of time and may require professional surveyor to locate and identify.
What do surveyors use to mark corners?
Surveyors use various tools to mark corners. One common tool is a stake. Stakes are typically wooden or metal and are driven into the ground to make a visible corner point on a surveyed property. Some surveyors will also use a spray can to mark locations with temporary paint, but this is less common than using stakes.
Surveyors may also use transits, levels, flags, and other marking devices to ensure an accurate survey. Moreover, GPS is also becoming an increasingly popular choice for surveyors to mark corners as well, as it saves time and money that would have otherwise been spent on manual surveying methods.
Ultimately, surveyors have a variety of tools at their disposal for marking corners accurately and efficiently.
How do you identify survey stakes?
Survey stakes are usually used as a reference point when conducting a survey, and they can vary in shape and size depending on the purpose. Generally, survey stakes are made of steel or wood and can be placed in the ground to mark the exact spot for survey measurements.
To identify survey stakes, look for a wooden or metal stake with a beveled top. In addition, survey stakes may be painted with a fluorescent colour like orange, yellow or blue, as this makes them more easily visible in the environment.
Survey stakes will also have a marker attached, such as a ribbon, flag or marker disc.
The marker will usually contain the name of the surveying firm, a serial number or other unique identifier, such as a company logo, marking the stake as part of the survey project. In addition, the specific measurements of the survey stake, such as the height and the width, should be written on the stake.
It is important to always ensure that these survey stakes remain in place and unchanged, as they are an important part of the accuracy of the survey.
What markers are used for tagging?
Markers come in various forms and can be used for a variety of purposes, including tagging. Common markers used for tagging include permanent markers, chalk markers, and paint markers. Permanent markers are usually the most popular choice, as they are highly visible and durable, creating a permanent or semi-permanent mark on most surfaces, including porous and nonporous materials.
Chalk markers, on the other hand, create a temporary but conspicuous mark which easily washes off most surfaces, including chalkboards and windows. Paint markers are usually used to create vibrant and durable marks on both porous and nonporous surfaces, and are available in a range of colors.
All of these markers can be used for tagging and can be useful in a variety of situations.
