ALTA Survey vs Topographic Survey: Which One Does Your Project Need?

One of the most common sources of confusion in commercial real estate is understanding the difference between an ALTA survey and a topographic survey.

Many property owners assume they serve the same purpose because both involve professional land surveying.

In reality, they answer very different questions.

Choosing the wrong survey can delay a project, while choosing the right one can save significant time and money.

What Is an ALTA Survey?

An ALTA survey is primarily focused on property ownership, title matters, and legal rights associated with the land.

The survey documents items such as:

• Property boundaries

• Easements

• Rights-of-way

• Improvements

• Access points

• Encroachments

ALTA surveys are commonly used during:

• Commercial acquisitions

• Refinancing

• Title insurance reviews

• Commercial lending transactions

The goal is to understand the property's legal and physical conditions.

What Is a Topographic Survey?

A topographic survey focuses on the land itself.

Instead of ownership issues, it documents:

• Elevation changes

• Contours

• Drainage features

• Trees

• Utilities

• Surface improvements

• Terrain conditions

Topographic surveys are frequently used during:

• Engineering

• Site planning

• Development

• Construction projects

The goal is to understand how the land physically behaves.

When You Need an ALTA Survey

Commercial buyers typically need an ALTA survey when:

• Purchasing property

• Obtaining financing

• Working with title companies

• Evaluating commercial risk

The survey supports due diligence and helps identify potential title concerns.

When You Need a Topographic Survey

Developers and engineers often request topographic surveys when:

• Designing a site

• Planning drainage

• Creating grading plans

• Designing infrastructure

The survey provides the information needed for design work.

Sometimes You Need Both

Many commercial development projects require both surveys.

The ALTA survey helps verify ownership conditions.

The topographic survey helps determine how the site can be developed.

Together, they create a much more complete understanding of the property.

Conclusion

ALTA surveys and topographic surveys serve different but equally important purposes.

Understanding the distinction helps commercial property owners choose the right survey for their project goals.
