This knowledge not only empowers you to make informed decisions but also helps you communicate more effectively with surveyors, real estate agents, and contractors.

In the following sections, we will explore the key elements that make up a property survey and offer guidance on how to approach reading one with confidence. By the end, you’ll be better equipped to interpret these important documents and understand what they reveal about your land.

Understanding the Symbols and Notations on a Property Survey

Property surveys use a variety of symbols and notations to convey detailed information about the land and its features. Familiarity with these markings is essential to accurately interpret the survey.

Common symbols include:

Boundary lines: Solid or dashed lines outlining the property limits.
Monuments: Small circles, squares, or crosses indicating physical markers like iron pins, concrete posts, or natural features used to define boundaries.
Easements: Dashed or dotted lines often labeled to show legal rights others have to use part of the property.
Setbacks: Lines depicting minimum distances structures must be from boundaries, roads, or other landmarks.

Additionally, surveys often use abbreviations such as:

R/W: Right of Way
P.O.B.: Point of Beginning (the starting reference point for the survey)
N/F: Now or Formerly (refers to current or previous owners of adjacent properties)
B.L.: Building Line

Understanding these symbols and abbreviations helps clarify the spatial relationships and legal constraints within the property.

Reading the Property Boundaries and Dimensions

Property boundaries are the most critical aspect of a survey. They define the exact perimeter of the land parcel. On the survey, these boundaries are typically drawn with heavier or continuous lines and are accompanied by measurements.

Key elements to focus on include:

Length of each boundary line: Usually shown in feet or meters.
Bearing or direction: Indicates the compass direction of each boundary line relative to north, often expressed in degrees, minutes, and seconds (e.g., N 45° 30′ 00″ E).
Corner markers: Points labeled and often marked with physical monuments on the ground.

When reading dimensions, note how the surveyor uses bearings and distances to describe each boundary line sequentially. This creates a closed polygon that represents the property. The Point of Beginning (P.O.B.) is critical as it anchors the entire description.

Identifying Easements, Rights of Way, and Encroachments

Easements and rights of way are legal permissions allowing others limited use of your property for specific purposes, such as utility access or roadways. These are typically shown on the survey as distinct lines or shaded areas labeled accordingly.

Encroachments occur when a neighboring structure or fence extends onto your property. They may be indicated by dashed lines or notes on the survey.

When analyzing these features, consider:

The location and dimensions of any easements or rights of way.
The purpose and restrictions associated with each easement.
Whether any encroachments could affect property value or require resolution.

Interpreting Topographic Features and Improvements

Surveys often include topographic details such as elevations, contours, and natural features. These are important for understanding drainage, slope, and potential construction challenges.

You may find:

Contour lines: Curved lines that indicate elevation changes, usually marked with elevation values.
Bodies of water: Lakes, ponds, or streams shown with specific symbols or shading.
Vegetation: Trees or wooded areas may be marked with symbols or notes.
Improvements: Existing structures like buildings, fences, driveways, and utilities are typically drawn and labeled.

Surveyor’s Certification and Legal Descriptions

At the bottom or side of the survey, look for the surveyor’s certification. This statement confirms that the survey was conducted according to professional standards and often includes:

The surveyor’s name and license number.
Date of the survey.
Reference to the legal description of the property.

Legal descriptions are often detailed text entries that describe the property’s boundaries using the metes and bounds system or lot and block references. These descriptions may be lengthy but are the official legal definition of the property.

Common Survey Terms and Their Meanings

Term	Definition
Metes and Bounds	A method of describing land by listing the compass directions and distances of boundaries.
Plat	A map drawn to scale showing the divisions of a piece of land.
Benchmark	A fixed physical point of reference, usually marked, with a known elevation.
Easement	A legal right to use another’s land for a specific limited purpose.
Setback	The required distance a structure must be from a property line or other feature.
Adjoiner	Neighboring property owner or parcel adjacent to the surveyed land.

Understanding these terms will aid in interpreting the survey and discussing it with professionals such as real estate agents, surveyors, or attorneys.

Understanding the Components of a Property Survey

A property survey is a detailed map that outlines the boundaries, dimensions, and key features of a parcel of land. To read a property survey effectively, familiarize yourself with its primary components:

Boundary Lines and Measurements

Boundary lines define the exact perimeter of the property. These are typically represented by solid or dashed lines on the survey. Measurements are usually given in feet and decimals, showing the length of each boundary segment.

Bearings: Indicate the direction of each boundary line relative to north, often expressed in degrees, minutes, and seconds (e.g., N 45°30’00” E).
Distances: The length of each boundary line, usually adjacent to the bearing.
Monuments and Markers: Physical markers such as iron pins, concrete monuments, or natural landmarks that identify key boundary points.

Legal Description

Surveys include a legal description that uses metes and bounds or lot and block references to define the property’s location and boundaries. This description is essential for legal and transactional purposes.

Improvements and Structures

The survey will show existing buildings, fences, driveways, and other improvements. Their location relative to property lines helps determine compliance with zoning setbacks and easements.

Survey Element	Description	Common Symbols
Boundary Line	Defines property edges	Solid or dashed lines
Monument	Physical marker at boundary points	Circles, crosses, or labeled pins
Building Footprint	Outline of structures	Solid outlined shapes
Easements	Rights of way or access	Dashed or shaded areas, labeled

Interpreting Easements, Setbacks, and Restrictions

Easements, setbacks, and restrictions significantly influence property use and development potential. Proper interpretation is critical when reading a survey.

Easements: These are rights granted to others to use a portion of the property for specific purposes, such as utilities or access roads. Easements are usually marked with dashed lines or shading and labeled accordingly.
Setbacks: Required distances between structures and property boundaries, mandated by zoning laws. These are often indicated by dashed lines parallel to the property boundary, showing the buildable area within the lot.
Restrictions: May include zoning classifications, flood zones, or deed restrictions noted on the survey or accompanying documents. They affect how the property can be used or modified.

When reviewing these elements, consider the following:

Verify the location and dimensions of all easements to understand any limitations on property usage.
Check setback lines to ensure proposed or existing structures comply with local ordinances.
Review notes or legends on the survey that describe restrictions or special conditions affecting the property.

Identifying Key Survey Symbols and Legends

Surveys use standardized symbols to represent various features, making the legend crucial for accurate interpretation. The legend provides explanations for symbols, line types, and abbreviations used throughout the document.

Common symbols and their meanings include:

Symbol	Description
● or ▲	Survey marker or iron pin
Solid line	Property boundary
Dashed line	Easement or setback line
Crosshatch or shading	Restricted or reserved areas
Circle with cross	Monument location

Additionally, abbreviations such as R.O.W. (Right of Way), O.H.W. (Overhead Wire), and U.E. (Utility Easement) frequently appear and should be referenced in the legend for clarity.

Using Measurements and Scale for Accurate Interpretation

All property surveys are drawn to scale, which allows for precise measurement and spatial understanding of the property layout.

Understanding Scale

The scale is typically indicated as a ratio (e.g., 1″ = 20′) or graphically with a scale bar. It defines how distances on the survey correspond to actual distances on the ground.

Applying Measurements
