Rule of Law:
In an eminent domain proceeding, an expert's valuation of condemned land is inadmissible if it is based on the value enhancement created by the condemnation project itself. An expert cannot define a separate economic unit or its highest and best use based on the very project for which the land is being taken.
Facts:
- Daniel and Sandra Zwahrs owned a 49-acre tract of land used for cotton farming.
- The property was already encumbered by a 50-foot-wide underground pipeline easement owned by Koch Gateway Pipeline Company.
- In 1995, Exxon Pipeline Company sought to condemn a new 50-foot-wide easement on the Zwahrs' property for an ethane pipeline.
- The new 1.01-acre easement sought by Exxon ran parallel to the existing Koch easement and overlapped it by approximately 82%.
- Neither the existing Koch easement nor the new Exxon easement interfered with the Zwahrs' ability to use the surface for cotton farming.
- The Zwahrs' valuation expert, Brad Kangieser, treated the 1.01-acre strip not as farmland, but as a self-contained 'separate economic unit' with a highest and best use as a pipeline easement.
- Kangieser testified that this separate economic unit was 'created' by Exxon's condemnation and that its value increased from 'negligible' to over $35,000 per acre because of Exxon's project.
Procedural Posture:
- Exxon Pipeline Company petitioned the Fort Bend County Court at Law to condemn an easement on the Zwahrs' property.
- Court-appointed special commissioners conducted a hearing and awarded the Zwahrs $2,264.80 for the taking.
- The Zwahrs objected to the commissioners' award and requested a jury trial in the county court.
- The trial court confirmed Exxon’s right to condemn the land via summary judgment, and the case proceeded to trial solely on the issue of valuation.
- Over Exxon's objection, the trial court admitted the testimony of the Zwahrs' expert.
- The jury awarded the Zwahrs $30,000 for the easement and $10,000 for the right to assign it, and the trial court entered judgment on the verdict.
- Exxon, as appellant, appealed to the Texas court of appeals.
- The court of appeals, an intermediate appellate court, held the expert testimony was properly admitted but struck the $10,000 award for the assignment right, reducing the judgment.
- Exxon petitioned the Supreme Court of Texas, the state's highest court, for review.

Issue:
Does an expert appraiser's testimony on the value of a condemned pipeline easement satisfy the requirements for admissibility when the expert defines the condemned land as a separate economic unit and determines its value based on the condemnation project itself?
Opinions:
Majority - Justice Hankinson
No. An expert's valuation testimony is inadmissible if it improperly includes project enhancement by basing the land's value on the condemnation project itself. The expert, Kangieser, violated the project-enhancement rule, which prohibits considering any increase in property value caused by the public project for which the land is being taken. Kangieser explicitly testified that Exxon's condemnation 'created the economic unit' he was valuing, meaning the unit did not exist prior to the project. Furthermore, he valued the land based on its worth to Exxon as a pipeline corridor, not its market value to the Zwahrs before the taking. This approach calculates the value to the taker, which is improper, rather than the loss to the landowner. Because the expert's methodology was fundamentally flawed and his opinion was based on value that only existed because of the condemnation, his testimony was irrelevant, unreliable, and inadmissible under Texas Rule of Evidence 702.
Analysis:
This decision reinforces the strict application of the project-enhancement rule in eminent domain valuation, serving as an important gatekeeping function for courts assessing expert testimony. It clarifies that experts cannot artificially sever a portion of a larger tract and assign it a unique, higher value based solely on the condemnor's specific purpose for the land. The ruling prevents landowners from receiving a windfall by valuing their property based on the condemnor's special need, rather than the property's fair market value absent the project. This precedent guides lower courts to reject speculative valuations that are not grounded in pre-existing market conditions and ensures that compensation reflects the landowner's actual loss, not the condemnor's gain.
