A land survey gives developers a clear picture of what they are working with before a single shovel hits the ground. Whether you are evaluating a site, planning a subdivision, or preparing for a commercial build, a land survey is one of the first steps you should not skip. Knowing what happens during the process helps you plan better and avoid costly delays.
Preparing the Property Before the Land Survey Begins
Before the survey crew arrives, there are a few things you can do to keep the process moving.
Give the crew full access to the property. Locked gates, overgrown brush, and parked vehicles slow things down. Clear the way where you can.
Gather any documents you have on the property. Old deeds, previous surveys, title reports, and recorded plats are all helpful. The more information the surveyor has upfront, the more accurate the work will be.
A few common obstacles that can affect the crew:
- Dense vegetation that hides existing markers
- Steep slopes or water features that limit movement
- Neighboring structures close to the boundary line
- Missing or disturbed property corner monuments
Connecticut properties, especially in older developed areas, often have buried or displaced markers from past construction. Letting your surveyor know about known issues ahead of time saves time in the field.
What Happens When the Survey Crew Arrives on Site
Once the crew is on site, the field work begins. This is the part most people picture when they think of a land survey.
The crew will look for existing property corners and monuments. These may be iron pins, concrete monuments, or other markers set by previous surveyors. They will also locate fences, walls, buildings, and other improvements on or near the property.
The crew collects measurements and notes. They record distances, elevations, and angles. Everything gets documented carefully because this data feeds directly into the final survey product.
Field work on a typical t development parcel can take anywhere from a few hours to several days. Larger parcels, irregular shapes, or properties with shared boundaries take longer.
How Surveyors Use Technology to Gather Accurate Measurements
Modern land surveying relies on precision tools that produce reliable results.
GPS receivers use signals from satellites to determine positions on the ground. In Connecticut, surveyors often use GPS in combination with the Connecticut State Plane Coordinate System to tie measurements to a statewide reference grid
Total stations are electronic instruments that measure angles and distances from a fixed point. They are especially useful in wooded areas or near structures where GPS signals may be blocked.
Data collectors record all field measurements digitally. This reduces errors and makes it easy to transfer data back to the office for processing.
These tools work together. GPS gives the big picture. The total station fills in the details. The result is a set of measurements that a licensed surveyor can stand behind.
Why Office Research Is an Important Part of a Land Survey
Field work is only half the job. What happens in the office matters just as much.
Surveyors review deeds, recorded plats, and historical maps. They search town land records and state archives. In Connecticut, land records go back hundreds of years in some municipalities. That history matters when setting boundaries.
The office research helps the surveyor compare what is on the ground with what the legal documents say. Sometimes those two things do not match. A deed may describe a boundary that conflicts with an old survey. An adjoining parcel may have been re-subdivided at some point. The surveyor works through these conflicts using legal interpretation and professional judgment.
This step is what separates a qualified licensed surveyor from a simple measurement service. Boundary location is a legal determination, not just a math problem.
Receiving and Understanding the Final Survey Results
When field work and research are complete, the surveyor prepares the final deliverables.
For most development projects, you can expect:
- A survey map or plat drawn to scale showing boundaries, improvements, and easements
- Property corner monuments set or confirmed in the field
- A written report or certification, depending on the survey type
- Bearing and distance calls that match the legal description
If you ordered an ALTA/NSPS Land Title Survey, the map will also show utilities, encroachments, access points, and other details required by title companies and lenders.
Review the final map carefully. Ask your surveyor to walk you through anything that is unclear. Pay attention to easements, setbacks, and any notes about adjoining parcels. These details affect what you can build and where.
Keep your survey on file. You will likely need it for permitting, financing, and future due diligence.
Frequently Asked Questions
1. How long does a land survey take?
Most standard boundary surveys on residential or small commercial lots take one to three days of field work, plus additional time for research and drafting. Larger or more complex sites can take longer.
2. Do I need to be present during the survey?
No. You do not need to be on site. However, being available by phone is helpful in case the crew has questions about access or property documents.
3. What if the survey finds an encroachment?
Your surveyor will note it on the map. From there, you work with your attorney to address it before closing or construction begins.
4. Can I use a previous survey instead of ordering a new one?
In most cases, lenders and title companies require a current survey. An old survey may also miss improvements or changes that affect the property.
5. What is the difference between a boundary survey and an ALTA survey?
A boundary survey establishes property lines. An ALTA/NSPS Land Title Survey goes further, showing improvements, easements, utilities, and other details required for commercial transactions and financing.
