A Land Surveyor is essential whenever you plan on building a house, buying or selling a property, or dividing your property amongst your children. Many land surveyor made it down to history. In fact, three of the four faces carved in Mt. Rushmore are land surveyors (Presidents George Washington, Thomas Jefferson and Abraham Lincoln were all three surveyors, Teddy Roosevelt was not.). Others popular names were Daniel Boone, Meriwether Lewis and William Clark (Lewis & Clark), Sir George Everest, Charles Mason & Jeremiah Dixon (of the Mason-Dixon Line fame) and author Henry David Thoreau practiced for a time in Concord, Massachusetts.

What is a Land Surveyor?

A land surveyor is a person with the academic qualifications and technical expertise to measure and plot the lengths and directions of boundary lines and the dimensions of any portion of the earth’s surface (including natural and other structures). That definition is quite a mouthful, but in actuality the field of surveying (geomatics) includes many other facets.

If you plan to purchase a lot, build your dream house, divide your property to your children, or simply want to know the details of a land property, a land surveyor is the best person to help you out. A land surveyor locates the boundary of your property and the location of your home within that boundary to determine if there are any encroachments by your neighbors onto you or vice versa. Common encroachments are fences, driveways, etc.

These days a land surveyor in the United States is regulated and licensed by the various state governments. In Georgia, the Georgia State Board of Licensure for Professional Engineers and Land Surveyors was established in 1935 to protect the public.  A land surveyor’s duty is “to safeguard life, health, and property, and to promote the public welfare by providing for the licensing and regulation of persons in the practices of engineering and land surveying. This purpose is achieved through the establishment of minimum qualifications for entry into the professions of engineering and land surveying, through the adoption of rules defining and delineating unlawful or unethical conduct, and through swift and effective discipline for those individuals or entities who violate the applicable laws or rules.”

How to become a land surveyor?

As of 2007, a newly licensed land surveyor is required to finish a four year degree in surveying or a closely related field, a four to eight years of on-the-job training under a licensed practicing surveyor. In addition to that, licensed land surveyors are mandated to attend 15 hours of continuing education annually to ensure that they are kept updated with the new know-hows that would help them on their professional growth.

What does a land surveyor do?

As part of a standard lot or mortgage survey of a property, expect your land surveyor to review tax maps, aerial maps, deeds, subdivision plats, zoning ordinances, subdivision regulations and possibly even flood maps. For a typical lot survey, the subdivision plat is the most important of these because it tells the exact dimensions of your lot and the relative location of your property corners. The surveyor uses this to locate and/or re-establish your property corners.

In the field, a land surveyor will search for your property corners along with some of your neighbors’ corners. If yours can’t be found, they’ll measure the distances and angles between all of the points, locate the improvements on your property, including your house, pool, out-buildings, retaining walls, fences, driveways, sidewalks, and other home improvements. Other improvements like sanitary sewer mains, storm drainage ways, overhead power lines and the like are located because these might indicate an easement across the property. The plat should show these, but may not in all cases.

Once all of the field information is gathered, the crew chief takes the field notes and prepares a preliminary sketch of the work. This is passed along to a draftsperson who prepares the final outline for your use. The draftsperson will check all of the maps mentioned earlier to make sure that all building setback lines and easements are shown on the draft. The surveyed distances and directions are compared to the plat distances and directions as well. Any discrepancies or encroachments are shown on the drawing. Your lawyer may use the draft to determine if any other legal work is needed during the closing. The mortgage company or the bank may also use the survey for their records.

So now, what do you have for your money. You have a drawing which shows your house on your lot. You should have stakes and/or flagging by all of your property corners. Make sure you know where they are located. The actual corner is marked by an iron pin or pipe of some sort. (The type of monument should be shown in your survey drawing.) You might also want to take a look at them at least once a year to make sure they’re still there. (Even animals mark their territory more often than that.)

A Topographic Surveyor also known as a Topo Surveyor collects the survey data to locate man-made and natural marks and its elevations on a particular portion of land. It normally comprises any man-made underground marks such as utility lines. It will also illustrate ground level installations such as utility poles, buildings, walls, and many other significant installations.

The utilization of standard topographic surveying procedures are commonly employed to provide accurate measured plan of terrain. It is also used during the mapping and graphing phases of projects to blueprint the locations and layout of the installations, road, buildings, and many other engineering and architectural projects in the construction industry.

Why Hire a Topo Surveyor?

The purpose of getting a Topo Surveyor to do topographic survey is to obtain an accurate trace and documentation of the present state of a parcel of land that will be constructed on; either a building, a wall, or any other construction activity. The design engineers make use of the topo survey as they plan the design and then the proposal of the final surface.

It is important to have this plan as this allows the Engineer compute, analyze, and estimate the amount of earth work that might be required. The Engineer will also be able to balance the amount of earth work to minimize the dirt to be taken off and on the construction site. The architect also makes use of the topo survey the same way as the Engineer does.

Additionally, the architect may plot the surface in 3D to picture out the finished look with the improvements he might add. This plot may be presented to the construction owner, building owner, or the land owner before the actual construction takes place. An accurate topo survey is of big help to ensure the installations and improvements fits in on the site within its boundaries.

Common Methods that a Topo Surveyor use

The two common methods of doing a topographic survey are Aerial Topo Survey and Conventional Topo Survey. How the topographic survey done would vary on the method the Topo Surveyor use. It is important that a topo surveyor know how to carry out both in any circumstances. So if you will need one, make sure he is professional and experienced both methods.

An Aerial Topographic Survey is done on the airspace. It is taken either in a helicopter or in an airplane at a defined distance above the ground level. Aerial photos of the ground surface are then taken and examined by the topo surveyor. This will allow him to envisage the ground surface through the structure of a stereo pair. By looking at the two overlapping aerial photos, the vantage points are determined.

A Conventional Topographic Survey is done when there is a need to get the accurate contour interval and spot elevations. The Aerial Topographic Survey is limited in the precise vertical and horizontal point location of the ground surface. These are just simplified elaboration of the two methods of topographic survey to provide you an overview. Read and research to learn in depth about them or ask a topo surveyor.

Boundary Survey Defined

Let’s first define boundary surveying. Boundary surveying is the verification of property lines of a parcel of land as detailed in the description in the deed. It may also show all the structures found on the property including any easements and encroachments, and also the restrictions imposed by local governing authorities.

To avoid unnecessary expenses and free you from frustrations brought by unexpected lawsuits, it is vital to conduct a boundary survey in the LaGrange area before purchasing or selling a parcel of land. A survey is also required before subdividing a lot, building structures or improving the property to make sure that you don’t end up having to move a building or resolve a boundary dispute with your neighbors.

Other Uses of a Boundary Survey

A boundary survey may also help you identify whether you are located in a floodplain, which would mean you are required to obtain flood insurance. A boundary survey in LaGrange is also very helpful in completing the requirements for a mortgage loan from a lending institution, which includes checking the accuracy of the description of the property in the deed and the presence of improvements, easements, and any encroachments.

Boundary Survey Costs

The cost of a LaGrange boundary survey depends on several factors, some of which can only be determined once the work has begun. Some factors are size of the lot, the terrain, the vegetation type, the season of the year (which greatly affects the growth of vegetation). The work begins with the deed research that can be started with the deeds or abstracts that the landowner may possess and can extend as much as going to the courthouse and putting together the pieces of the deed. The job could get more complex if the property involved has been passed on through several owners over the years. Some may have sold off a portion of the parcel or may have added to adjacent lots. The more of these additions and subtractions can significantly impact the complexity of the work to be done, which consequently adds to the survey cost.

Boundary Survey Drawing

After the boundary survey is done, a landowner should expect to get a survey drawing that contains a sketch of the survey findings and the legal description of the property. It is also expected that proper markings of the property lines and corners have been placed, which are usually bright-colored ribbons or paint, wooden stakes, or concrete monuments. Others survey projects may or may not include a drawing or report, depending on the services agreed upon.

Many have heard of “Big Brother” being able to track our movements. One of my favorite TV shows is “Person of Interest” where a secret machine keeps track of all conversations and people’s “criminal intent” in order to help the heroes stop the crimes before they happen.

While I’m SURE that there are tracking capabilities in most cell phones and different government agencies CAN track our locations, we might be a ways away them being able to determine criminal intent.  But there IS a recent application in England that I found very interesting.

Nestle (yes, the chocolate company) is placing GPS Trackers in six KIT KAT bars in their aptly named “We’ll Find You” marketing campaign in the UK. When the person opens the package it notifies KIT KAT and the prize delivery team will find them within 24 hours and present them with a check for £10,000 (about $16,000.) See the article here.

Just about all new type cell phones, all smart phones, iPads and other tablets, lots of cars (more than you think), public transportation vehicles, golf carts, and watches have GPS devices in them now days. Another place they are, and rightly so, are in ankle monitors used by law enforcement. But, what you might not realize is that the electronic devices mentioned above can work just like the ankle monitor. Now, while it is true that you can disable the GPS tracking device in your cell phone or tablet, that doesn’t give all of us complete comfort in walking around with these devices on us.

Now, I’m not trying to be a conspiracy wonk here, but it is POSSIBLE that this could be taken advantage of by well-meaning agencies. And, as we know, law enforcement can make mistakes in identifying the correct suspect.  Of course, as a licensed land surveyor myself, I WANT emergency services to be able to find me if and when I need their service, so this is a double edged sword. Most of us probably have nothing to worry about in this regard, but if you worry about this sort of thing, it could keep you up at night.

Even as a licensed land surveyor, having used GPS technology in land surveying for almost 20 years, I still trust them more than I should.

One example is when I was in an unfamiliar town my GPS navigation device told me to take a “road” to the right. I slowed down and attempted to turn but it was a power line.  Not wanting to believe that Gizell was wrong (yes I named her), I went to the next street and turned and tried to find the “road” further back. I ended up driving down the sandy power line, which turned into a bike lane until I was finally stopped by a gate. As I backed down the bike lane looking for a turn-around spot I thought, “maybe this wasn’t a road and maybe my GPS device is fallible.” Of course, I soon justified Gizell by recalling that a human had to “digitize” the roads in and she just did what they programmed her to do.

If you need to turn off your GPS tracking device in order to sleep tonight, call your device’s customer service line and stay away from KIT KAT bars. If you would like to find out how GPS surveying technology can help you in surveying your property boundary, call a Licensed Land Surveyor at LaGrange Surveying at (706) 407-2722.

ALTA Survey Standards Lead to Consistency

Most states have widely varying standards for surveying. Thus, ALTA Surveys follow a national standard for surveying aimed to generate consistency regardless of the location of the survey. This type land survey is usually done on a multi-family residential or commercial site and when the owner and/or lender are from different states. But more often than not, it is prepared for commercial properties because it provides the information needed in order to insure the title to the land. Commercial developments may also require improvements to a high level that is also obtained through this survey.

ALTA Title Surveys are very complex and are commonly more costly than surveys following state standards because it takes more time and effort.

Costs for such surveys could be up to 50% – 200% more than a similar boundary survey. It is also important to note that the more restrictive standard is followed in the survey if the state standard is more restrictive on a certain aspect than the ALTA standard. An ALTA Title Survey must show all data including boundary lines, main building location and all its improvements, location of ancillary buildings, rights-of-way, and easements or access rights by utility services such as water, telephone, gas, railway and other utilities. A helpful tip in outlining the scope of services of the land surveyor is to thoroughly go over the elements of “Table A – Optional Survey Responsibilities and Specifications”.

ALTA Survey Requires Title Committment

Before an ALTA Title Survey can be completed, there must be a current title commitment. This is where the land surveyor will refer for the legal description of the property and all legal encumbrances or exceptions. The areas of ownership, encumbrances, and improvements will be presented graphically including encroachments, if there is any.

All the affected parties; the buyer, seller, lender, and title insurance company must be indicated on the ALTA Title Survey certificate. The land surveyor and the title insurance company must closely work together in order to illustrate comprehensively all matters affecting the ownership of the land and improvements.

Requirements for an ALTA/ACSM Land Title Survey as detailed by the American Land Title Association, National Society of Professional Surveyors and the American Congress on Surveying and Mapping is certainly met through an ALTA Title Survey.

What is Land Surveying?

Land surveying is the art and science of accurately measuring parcels of land. Measurements such as dimensions, lengths, boundary lines, including structures within the area are all precisely determined through a land survey. These measurements are used to establish land maps, boundaries for ownership or for governmental purposes. It is a detailed study of every physical and cultural property of the land, whether above or beneath it, to illustrate it in usable form. 

 Data is gathered through observations, research, field measurements, and data analysis for establishing property boundaries. Records from previous surveys and government records will strengthen the reports made after the survey. 

What covers land surveying?

A land survey is classified according to the purpose or why the survey is being performed. Some of the common types of land survey are boundary surveys, topographic surveys, partition or subdivision surveys, flood elevation survey, property line adjustment survey, and extended title insurance coverage survey. 

Other services such as mapping, construction layout surveys, judicial surveys, registered land surveys are all part of land surveying. It is an essential element in every development of the environment especially in the fields of construction, transport, communication, mapping, and most especially in the definition of legal boundaries for ownership.

The key component in the field of land surveying is the land surveyor. A land surveyor is a person that takes charge of every activity that transpires during a land survey. It is the surveyor who makes the research and data gathering and even interpretation and analysis of all data wherein translation of all data gathered is crucial and should be checked, attested, and sworn in the law to be true and correct. It is important then for you to choose a land surveyor with the highest degree of expertise and who can assume responsibility for the complex tasks at hand. It should be emphasized that only a surveyor who has knowledge of the elements of geometry, trigonometry, engineering, mathematics, physics, and the law are expected to have the best land survey outcomes.

Land surveying – dated back in history

Land surveying is a profession as old as the Egyptian times yet its importance to the human race still lives on. It is the best method to settle disputes over land ownership, it gives a clear picture of what buildings are suited to be constructed in a given land area, and it’s a convenient way to determine the exact dimensions of real estate to be purchased or sold. 

Optimum potential of the land you own can only be defined once you have a land survey. Whether you are planning to put it on the market, or should you want to use it for commercial purposes, a land survey must back you up if ever questions regarding everything about the land arise. Land surveying will provide a sense of security and peace of mind to every land owner and even to the future buyers.

Land surveying will always be an integral part in protecting real estate and upholding of laws governing the utilization and distribution of your land assets.

Today, man-made constellations are in orbit. Their purpose is to provide instant, exact and global positioning information. This global positioning system of GPS is revolutionizing the modern construction sites, automating and guiding land surveying equipment, providing instantaneous circles and volume gap, simplifying total and controlled surveys. Nearly everyone involved in the land surveying and construction industry has heard something about satellite positioning technology or maybe you or someone you know is already using it. Whether an operator or a casual observer, there are still many questions about how this exciting system really works.

These positioning satellites don’t stay in one place like the stars; they orbit the earth about twice a day. Constantly transmitting uniquely identified radio signals that can be perceived by specialized units on earth. These signals are used to precisely measure the distance to the receiving instrument from each satellite visibly overhead.

Just as stars have exact locations in the sky, the locations of the GPS satellites are also defined, becoming orbiting reference points. Using a process based on triangulation, a GPS receiver processes the signals from multiple satellites to compute an accurate position on Earth, which is why it is widely use in land surveying.

For mobile applications that require high accuracy, such as three dimensional machine control, there are two requirements that must be met. First, the signals from a minimum of five satellites must be received at all times. And second, those five satellites must be distributed across the sky. This is called Dilution of Precision or DOP. The simple rule of thumb is this, the more satellites received the better your system will perform.

All land surveying receivers incorporate standard GPS tracking technology; unfortunately the GPS satellite constellation alone cannot continuously make the minimum requirement of accurate mobile positioning. For any given location, there are times in a day when there are less than five available satellites or very poor DOP.

Now, consider a land surveying job site with trees, buildings, or other obstructions when satellite receptions are easily be further reduced. All land surveying GPS receivers suffer this same problem because they all use the same satellites to operate.

Even the planned signal modernization to the GPS satellites won’t solve this problem. An obstruction that blocks one signal blocks all signals from that satellite. A land surveying equipment provider has solved this problem. The solution isn’t adding more signals from the same satellites; it’s adding more satellites.

Today, there is a second positioning satellite constellation in operation, the Glonass System. This positioning system is operated and maintained by the Russian government; much like the GPS is operated and maintained by the United States government; combining these two satellite constellations give land surveyors access to 38 different satellites; 14 more than a GPS-only system.

The additional satellites mean stronger and more accurate positions and better performance in obstructed land surveying areas. These additional satellites mean maximum up time in all land surveying locations, in all conditions.

The Daily Republic in South Dakota published an article that talks about an earthen dam that recently failed because of a nine-inch rainfall last 29^th of July 2010. The heavy rainfall overwhelmed the dam’s capacity causing it to fail.

No injury was reported on the said event. The said damn was built in 1935, as were a number of them during the Work Programs after the Great Depression. In 2007, it was inspected by a Department of Game, Fish and Parks Engineer and he noted that they “were satisfied with the condition of the dam” during that time. It was then again inspected in 2008 and it was said that the dam breach “was caused by an extraordinary natural event and not by any structural weakness in the dam.” (Photograph by Laura Wehde/The Daily Republic).

Earth dams are almost too numerous to count around the country. In fact, you might just be living near one without you knowing it. A great percentage of these dams were built over 70 years ago and, in many cases, the owners today were not the same ones when they were initially built. For this reason, maintenance and inspection of these dams became less popular.

FEMA estimates “there are over 80,000 dams in the United States”, and that approximately “one third of these pose a ‘high’ or ‘significant’ hazard to life and property if failure occurs.”

The South Fork dam, the country’s worst dam failure disaster in May of 1889, took over 2200 lives and almost half of which were under 20 years old. This incident happened in the town of Johnstown, PA, thus it was known as the “Johnstown Flood”. A 37-foot high wall of water hit Johnstown, located 9 miles downstream from the dam. It almost destroyed the entire city as 1600 homes and 280 businesses was flushed away.

In March 1928, the St. Francis Dam in California also failed. This caused a legislation to be enacted in and around the said state. This, and other later legislation led to life-saving advance warning when the Baldwin Hills dam near Los Angeles, California failed on December 14, 1963. Because of the advance warning which enabled the evacuation of approximately 16,500, the casualties from dam failures has significantly decreased to 5 individuals

Even though there have been far less loss of lives in the United States from dam failures since the 1970’s, reports that…

there were 132 dam failures and 434 “incidents” between January 2005 and January 2009.

Of course, It should be noted that the failure of the earthen levees near New Orleans, LA during and after Hurricane Katrina are purported to be responsible for killing more than 1000 people.

Failure in The KaLoko Dam on the Island of Kauai, Hawaii in March 2006 has resulted to the death of 7 people. Two years after the said incident, developer James Pfluegar was indicated for manslaughter and reckless endangerment in relation to the dam failure. The incident had caused the country of Kauai and the State of Hawaii to pay out over $9 Million in of lawsuits after the failure.

Cause of Dam Failures

Heavy rains cause overtopping, which is by far the most common cause of dam failures. Dam spillways and structures are typically not designed for more than a 1-percent chance (aka 100-year) storm event. When a rain event exceeds this, the water starts to travel outside of the control spillway. This causes erosion of the soil on the dam from the excessive amount of water traveling over it. It is also possible for overtopping to occur from smaller rain events because of debris blockage of the outlet structure or spillways or because of settlement of the dam crest.

Foundation defects, including settlement and slope instability, cause about 30% of all dam failures.

Seepage or Piping causes the remaining 20% of the U.S. dam failures. Piping is the internal erosion caused by seepage under and through the dam. This usually happens around structures such as pipes through the dam and spillways. Seepage can also be caused by animals, like beavers, muskrats, groundhogs, and other rodents, burrowing in the dam, by roots of trees growing on the dam, and through cracks in the dam.  All earth dams have seepage resulting from water permeating slowly through the dam and its foundation. But this seepage must be controlled or it will progressively erode soil from the embankment or its foundation, resulting in rapid failure of the dam.

What Should You Do To Protect Home?

Since the failure of a dam causes flood, your best option is to avoid building in a flood zone, unless you elevate and reinforce your home. Have your area surveyed and investigated for dam failure and flood determination so you’ll know if your dream house is safe to be constructed in that certain area.

Do you live downstream from a dam? Is the dam a high-hazard or significant-hazard potential dam? To find out, contact your state or county emergency management agency and/or visit the National Inventory of Dams. There are around 5,132 dams on the National Inventory in Georgia. And among those, 640 are listed as high or significant hazard potential dams.

If you live downstream from one of these dams, find out who owns and regulates the dam. This information should also be available from the National Inventory of Dams.

Next, find out if there is an Emergency Action Plan in place. Again, consult your state or county emergency management agency. (Georgia Environmental Protection Division)

FEMA's Flood Insurance Rate Maps (FIRMs) or just Flood Maps are provided after a flood risk assessment has been completed or updated for a community.  This study is known as a Flood Insurance Study.  The FIRM gives you the Base Flood Elevations (BFEs) and insurance risk zones in addition to floodplain boundaries.  The FIRM may also show a delineation of the regulatory floodway. 

Once the "insurance risk zone"  (commonly referred to as the flood zone) is determined, actuarial rates, based on these risk zones, are then applied for newly constructed, substantially approved, and substantially damaged buildings.  FEMA uses these rates to determine the insurance rate you will pay for flood insurance

FEMA's Digital Flood Maps

FEMA discontinued the production and distribution of paper flood maps in 2009 as part of its Digital Vision Initiative. This affected all the Flood Maps, boundary information, and study reports. However, clients can still view the products for free through their website or buy them in digital format.

To view these flood maps online, go to FEMA's Map Service Center and key in your address (hi-lited area shown here) search for your home.  This will prompt you to then select the map that covers your area.  The Flood Maps are somewhat cumbersome to use online. It is best to go through the tutorial on the bottom right of the address search page for an easier and more effective use of the GIS map.

Montgomery Flood Maps by FEMA

If you are located in the City of Montgomery, you might also want to check the Phenix City Interactive GIS maps for more information and a little easier interface. Check the FEMA Flood Insurance Rate Map box on the left to view the flood zones on this map.

Call Phenix City Land Surveying at  (334) 408-4311 or  contact us if you need help with this process or if you discover you are near a flood zone and need an elevation survey completed.  We are here to help you minimize your flooding risk.
