Kent A. Sick § 1.01. Abstract. This paper begins with a general review of major scientific and appraisal writings since 1993 on the subject of EMFs and their effect on real property value. Further, there is a brief examination of current cases, statutes, and municipal regulations on the subject. Finally, the authors explore the pros and cons of corridor valuation for expansion of existing utility easements, with an emphasis on the right-of-way marketing efforts of several major utility companies and using corridor sales data as opposed to traditional "at the fence" methods. § 1.02. Review of Original Conclusions. In 1993, one of the authors took a long look at the then-current relationship between electric transmission lines and surrounding real estate values. In the article, "Properties Near Power Lines and Valuation Issues: Condemnation or Inverse Condemnation?," this author presented a broad overview of the subject including the following: An examination of scientific inquiry of the day concerning the existence
of actual adverse effects of electromagnetic field radiation (EMF) from
major transmission lines on human health; Since 1993, there have been significant developments on all fronts. Scientifically, the debate has reached the lofty halls of the Council of the American Physical Society and the U.S. Academy of Sciences. Real estate professionals, however, even those performing studies on behalf of the power line companies themselves, are continuing to conclude that power lines are bad for property values. On the case law front, in general, there is in general continuing support for the admissibility of expert appraisal evidence based on "fear in the market place," but there is growing criticism of testimony deemed to be "junk science," fueled by the Daubert and Robinson opinions1. § 1.03. Scientific conclusions: still inconclusive. Scientific investigation of the potential adverse impacts of radiated fields has widened to include not only the low frequency emissions of transmission lines, the subject of this paper, but also high frequency emanations from cellular phones and microwave towers. Though the data indicating that higher frequency emissions may be harmful seems much more settled in the literature than that concerning low frequency emissions, it is probable that public perception blends the two such that general fear of EMF exists in the public mind across the board. [1] Good news. In an attempt to quell some concerns, the Council of the American Physical Society, a body of renowned American physicists, issued the following statement in 1995: The scientific literature and the reports of reviews by other panels show no consistent, significant link between cancer and power line fields. . . . While it is impossible to prove that no deleterious health effects occur from exposure to any environmental factor, …the conjectures relating cancer to power line fields have not been scientifically substantiated2. One year later, the U.S. Academy of Sciences joined the physicists in their conclusions: …[T]he current body of evidence does not show that exposure to these EMFs presents a human health hazard. Specifically, no conclusive and consistent evidence shows that exposure to residential electric and magnetic fields produces cancer, adverse neurobehavioral effects or reproductive and developmental effects3. These statements were foreshadowed by a British group of epidemiologists known as the Advisory Group on Non-ionizing Radiation ("AGNIR") in 1994. AGNIR, however, reserved judgment on the issue with regard to childhood leukemia: "…epidemiological studies [do] not establish that exposure to EMFs is a cause of cancer although taken together they suggest that the possibility exists is the case of childhood leukaemia."4 [2] Bad news. The most recent official pronouncement on the subject reopens the debate and muddies the waters more than ever. In June of 1998 an expert panel convened by the National Institute of Environmental Health Sciences ("NIEHS") at the behest of Congress issued an alarming press release. The panel concluded that low frequency EMFs, like those surrounding transmission lines, should be classified as a Group 2B human carcinogen under the International Agency for Research on Cancer classification scheme. A Group 2B classification means that "the agent (mixture) is possibly carcinogenic to humans. The exposure circumstances entail exposures that are possibly carcinogenic to humans." 5 [3] Ugly news. As both the following look at subsequent appraisal literature and common sense make clear, the continuing scientific uncertainty over the adverse health consequences of EMFs only serves to perpetuate the debilitating effect of power lines on abutting property values. § 1.04. More Recent Literature and Surveys. [1] Hamilton/Schwann. In 1995, two academics named Stanley Hamilton and Gregory Schwann published a highly empirical study of residential home prices in Vancouver, British Columbia. The study contrasted sales in four separate Vancouver neighborhoods of residences adjacent to power lines of 60kV or greater from 1985 to 1991. The sample size was impressive, containing 12,907 transactions in the four study areas. The percentage decreases in property values were not as great as those originally measured in the Houston area in this author’s 1993 study. Hamilton/Schwann nevertheless concluded to an undeniable drop in value: "We find that properties adjacent to a line lose 6.3 percent of their value due to proximity and the visual impact."6 The well-supported findings presented in this article lead one to conclude that the depressing effect power lines have on property values is not merely an American phenomenon. [2] Cowger/Bottemiller/Cahill. These three real estate professionals employed by the Bonneville Power Administration in Portland, Oregon, published another study in Right of Way magazine in 1996. This study again concluded that overhead transmission lines negatively influence value: "Overhead transmission lines can reduce the value of residential and agricultural property. The impact is usually small (0-10%) for single-family residential properties. The greatest impacts have been measured in intensively managed agricultural property (irrigators, etc., and in rural, second (vacation) home developments."7 [3] Development Strategies Survey. In 1995, a group of real estate consultants in Missouri conducted a survey of residential brokers and salespersons, some 167 professionals, all in the St. Louis area. The results were published in a study concluding that 54% of those surveyed believed high voltage overhead electric transmission lines ("HVOETLs") "very negatively affected" residential property values; another 23.8% considered HVOETLs to "somewhat negatively" affect property values.8 [4] Rikon article. In January of 1996, a New York attorney named Michael Rikon published an article in the Appraisal Journal following up on the landmark Criscuola decision, which had just been handed down at the time of this author’s original paper.9 Criscuola was the landmark New York Supreme Court decision allowing appraisal evidence in transmission line cases to be based upon fear in the market place rather than actual epidemiological evidence of adverse health effects from EMFs. Rikon noted that the Criscuola court’s embrace of the "fear in the marketplace" theory of damages had spread beyond transmission line cases to include actions against a cell phone provider to stop construction of a tower, against Amtrack to oppose electrification of its tracks in New York, and in increasing numbers of inverse condemnation cases.10 Clearly, the Criscuola buzz continues to grow. [5] Gimmy seminar. In late 1994, Arthur Gimmy, MAI, presented a seminar before the EMF Regulation and Litigation Institute11. In part, the seminar presented a matched-sales analysis of California residential property that indicated diminutions in lot values from properties abutting power line easements of 18% to a whopping 53.8%12. While the methodology employed in this study does not seem as rigorously empirical as that used by Hamilton/Schwann, it may demonstrate that California landowners are more sensitive to the EMF property devaluation issue than those in British Columbia. [6] LCRA Commissioned Study. More recently, in late 1997 the Lower Colorado River Authority commissioned a study to quantify the property value impact of electric transmission lines in and around Georgetown, Texas13. The study was performed by a local MAI who the LCRA had also hired to do all of the appraisal work for the concurrent acquisition of numerous easement parcels for a new 138kV line. Well over 100 real estate transactions were analyzed, including both sales from eight different residential subdivisions and vacant land sales. Even in a study prepared for a condemning entity in connection with a number of pending acquisitions, undeniable value damage was found: From the data analyzed, it is concluded that from an overall value perspective, an electric transmission line easement has less than a 10% impact on price, and in most instances, less than a 5% impact on price.14 It is important to note that the appraiser in this study was referring to a 10% overall impact on price, not just on the value of the land immediately affected by or adjacent to the easement. For those areas, he reached a specific conclusion: …[I]t is concluded that the area located within an electric transmission line easement has a 90% diminution in value due to the presence of the easement. … [and] [i]t is concluded that an area 200 feet wide adjoining the proposed easement has some diminished value. The extent of the diminished value can be dependent on various factors which would include the location of the easement relative to the whole tract, and the physical characteristics of the remainder.15 This author’s original 1993 estimate as to the probable width of an effective easement was 150’ on either side of the actual easement16. The fact that a study prepared on behalf of a major Texas condemnor reached a similar conclusion demonstrates the validity of the effective easement theory. § 1.05. Municipal Regulations and Statutes: More Bad News. [1] Set-back requirements. Since the original article, this author has become aware of building set-back requirements from HVOETLs imposed by a few Texas municipalities that convert effective easements from theory to undeniable reality in some jurisdictions. For instance, the Town of Flower Mound, Texas (just north of Fort Worth) mandates that no building be constructed within 100’ of the edge of the right-of-way or easement of any high voltage (60kV or higher) electrical transmission line.17 Although its requirements are not as concrete as those of Flower Mound, the City of Red Oak, Texas (south of Dallas) has enacted similar restrictions tied to height. In Red Oak, buildings in residentially zoned areas adjacent to elevated power lines or towers must be set back an additional one foot for every foot by which the neighboring transmission line or tower exceeds 15’18. For instance, if a residential property abuts a 90’ high transmission line or tower, an additional 75’ building setback would be imposed. The City of Plano has related provisions tied to tower or line height19. Obviously, all other things being equal, a purchaser comparing properties affected by these regulation-imposed effective easements would pay something less for them than for other competing properties unaffected by such setbacks. [2] Potential Legal Liability. In addition, the Texas Health and Safety Code contains at least one provision related to high voltage power lines (anything over 600 volts) that the authors suspect could have a chilling effect on the values of the underlying servient estate beneath an electric line easement. Chapter 752 of the Code sets out a host of prohibited activities in and around power lines, such as restrictions on operation of certain types of machinery or structures near the line without posting a statutorily-required warning20. Curiously, the Texas Legislature even saw fit to declare violation of this chapter a criminal offense punishable by jail time, fines, or both.21 Perhaps the most damaging provision, however, is the one that establishes civil liability to the power line company for any contacts with the line caused by violations of the statute: If a violation of this chapter results in physical or electrical contact with a high voltage overhead line, the person, firm, corporation, or association that committed the violation is liable to the owner or operator of the line for all damages to the facilities and for all liability that the owner or operator incurs as a result of the contact. 22 [Emphasis added.] While at first blush an underlying landowner’s liability to a power line company for a downed transmission line or tower seems obvious, the effective global indemnity of the line operator contained in the last clause could definitely negatively impact underlying property values. Consider this hypothetical example. Developer John, whose 300 acre tract is bisected by a 138kV power line easement, is preparing the surface of his newly subdivided tract for roadways with a bulldozer. Inadvertently, the operator of the bulldozer bumps one of the towers supporting the line. The tower, having been incorrectly engineered and installed by the power company, immediately falls over on the operator, instantly killing him and knocking out power to all users serviced by the line. One of the users, a major semiconductor manufacturer, sues the power line company for consequential damages flowing from the manufacturer’s closure of two full shifts while the line was being repaired and re-energized. Can Developer John possibly be held liable? In 1984, a Federal Court sitting in Texas concluded that the "all liability incurred" language of the statute provided full indemnity to an electric utility for any claims arising out of any violation, including liability for the electric utility’s own negligence.23 Subsequently, in 1991 a Texas appeals court held the language extended even to the "violator" being responsible for the power line operator’s attorney’s fees, costs, and interest.24 There are few – if any – other types of "improvements" to real estate that require an underlying landowner to be responsible for someone else’s negligence. §1.06. A Quick Case Review. [1] Old cases. The author’s first look at power lines and diminished property values in 1993 contained synopses of three cases from literally across the country standing for the proposition that fear in the minds of potential purchasers of real estate was an admissible element of damages in a statutory condemnation proceeding.25 These cases – Criscuola26 from New York, Ryan27 from Kansas, and Daley28 from California – have all survived the appellate process and continue to be controlling law in their respective jurisdictions. One important distinction has been drawn from this principle of law, however, at least in California. In San Diego Gas & Electric Co. v. Covalt29, a landowner tried to make out a claim for inverse condemnation caused by a pre-existing power line based in part on a diminution in value of his property due to fear in the marketplace of EMFs. The court declined to accept that Daley controlled. The court held rather that while fear in the marketplace was an acceptable element of damages in a conventional condemnation, such fear could not create a new cause of action for inverse condemnation when the power line in question already exists.30 [2] Coker. One relatively recent Federal case merits discussion, though it does not directly involve power lines. In U.S. v. 14.38 acres of Land (Coker)31, the Fifth Circuit Court of Appeals embraced the fear in the marketplace theory of damages. Coker involved a condemnation for a new levee which the landowner’s appraiser testified would create "fear" that land on the river side of the levee would be significantly more likely to flood, thus decreasing its market value. The court upheld the admissibility of this testimony in this context, relying on a prior power line case: Causes of diminution of market value, [such as] the construction of a powerline carrying high voltage electricity across a tract of land which create in the general public fears which make the property less desirable and thus diminish the market value of the property are proper to be considered, though as a separate item of damage might be too speculative and conjectural to be submitted to the Court.32 Interestingly, the lower court in Coker had excluded entirely the testimony of Coker’s appraisal expert, finding essentially that his opinions were "junk science" under the Supreme Court’s now famous 1993 opinion in Daubert v. Merrel Dow Pharmaceuticals, Inc.33 In holding that Coker’s expert should have been allowed to testify, the court observed: The value of property taken by the Government…is largely a matter of opinion. Since there are no infallible means of determining with absolute conviction what a willing buyer would have paid a willing seller for the condemnee’s property at the time of taking, eminent domain proceedings commonly pit the Government’s valuation experts against those of the landowner…Recognizing the critical role of expert witnesses in these cases and the strong interest on both sides that compensation be just, trial courts should proceed cautiously before removing from the jury’s consideration expert assessments of value which may prove helpful.34 The Coker court thus acknowledged the obvious: "how much" in any given condemnation case, particularly ones involving the establishment or expansion of high voltage power lines, will always be a matter of opinion for competing appraisal experts to set forth and for a fact finder to ultimately decide. § 1.07. Newer Issues: Utility Corridors Can Be Extremely Valuable. Within the past few years a new industry has emerged requiring the use of right-of-way corridors for communication lines and fiber optic cables. These communication lines are responsible for transmitting data involving national security, banking, world wide web, teleconferencing, and most types of data transmission. What better avenues to install the hardware necessary for this product than existing utility corridors, which already offer the physical, economic, and legal attributes for this kind of use. [1] ATF or True Market Value? A Question of Highest and Best Use. Acquiring rights for Communication lines by condemning entities has been fairly rare until recently, primarily because there was no need. As the need for communication lines increased, the utility companies have begun to acquire these property rights. Naturally, the valuation issue is now becoming a factor. The position taken by most companies with the power of eminent domain is to value the property rights as simply the pro rata share of the easement value as determined by the "at the fence" (ATF) prices. From a pure appraisal perspective, this method is inappropriate and does not conform with generally accepted appraisal practices set forth in the Uniform Standards of Professional Appraisal Practices (USPAP). "In developing a real property appraisal, an appraiser must be aware of, understand, and correctly employ those recognized methods and techniques that are necessary to produce a credible appraisal."35 The foundation of proper appraisal methodology is an analysis of a property’s value based on its highest and best use, defined as "[t]he reasonably probable and legal use of vacant land or an improved property, which is physically possible, appropriately supported, financially feasible, and that results in the highest value."36 The basis for appraising property rights of this type is plainly set out in the Appraisal Institute’s text book, which is universally accepted as the best authority: "Analysis of the highest and best use of the property as though vacant and of the property as improved is essential in the valuation process."37 In the evaluation of a taking of additional property rights within an existing right of way corridor, very rarely can the highest and best use be anything other than for those kind of uses that are already found within the corridor. That being the case, those property rights being acquired must be appraised based on that highest and best use. ATF prices rarely have anything to do with the market value of property rights within the established corridor. [2] Corridor Property Availability. The proper method for appraising properties within a corridor is to use market data occurring within a corridor. There is a vast amount of existing corridor space currently available, literally hundreds of thousands of miles. If buyers and sellers for a particular type of property exist in the market place, then market data will be available to the appraiser. Consider the following examples of corridor property availability. Union Pacific advertised on the rear cover of Right of Way from at least
1993 through 1996.38 With a map showing the approximate locations of
their corridors, the ad states: Available Throughout the West Transmission Lines Signboard Sites One major Texas power line company advertises the sale or lease of rights
of way corridor properties located throughout southeast Texas for various
uses, including mineral leasing, commercial leasing, drainage easements,
roadways, pipeline easements (private), commercial large-demand pipelines,
and for communication uses. In order to expand the fiber routes beyond the core river system, the LCRA seeks proposals from Carriers. Depending upon the amount of fiber requested in a proposal, LCRA will install the fiber cable and license dark fiber reserve capacity to a third party. The LCRA is positioned to leverage its transmission ROW and towers, which includes approximately 2300 miles of transmission lines and over 200 electric substations.39 These advertisements have all the earmarks of typical market forces at work. Without doubt, these examples are indicative of market data for rights of way throughout Texas and the United States for established easement corridors. [3] What Happened to The Landowner’s Rights? Usually forgotten are the underlying rights of ownership of the landowner. When a utility company has obtained the right of way and created a corridor, but has not obtained a specific property right (i.e. a fiber optic cable), then the value to the property owner should be assessed or appraised based on its highest and best use. This conclusion necessitates that market data (sale and lease) within utility corridors be used for comparison purposes. It is inappropriate to use ATF prices when evaluating the rights of ownership within the corridor for a condemning authority and ignore the data and evaluation methods used when the same rights are sold or leased to users of corridor properties. [a] Expanding an Existing Easement: The Condemnor’s Valuation. Consider this scenario. A major utility company owns a prior easement which grants the rights for three electric transmission lines across an approximate 110 acre tract of land in central Texas. A petition is filed to obtain additional property rights within the easement for the "right to construct, place, operate, maintain, reconstruct, replace, rebuild, upgrade, remove, inspect, patrol and repair communication lines and facilities and all necessary and desirable appurtenances on, across, and within the property…" The proposed easement is within the existing 75-foot easement and the length is approximately 1849 lineal feet or about 113 rods. Citing sales data averaging about 150 acres in size and prices averaging about $1000.00 per acre, the utility company’s appraiser concludes to a market value for the communication easement with the following: 3.24 acres (area of the existing easement) x $ 1000.00 per acre = $3,224 Value of the property rights within the existing easement 95% or $3,078 Value of the Communication Easement 5% or $162 [b] The Landowner’s Valuation. Assume for purposes of this hypothetical that the condemnor utility company had recently leased a fiber optic line to a communication company on the basis of $21,312/year, equating to a value of $266,400 (based on a capitalization rate of .08) or $832 per rod. Utilizing this and other actual market data of sales and lease information from comparable corridor uses averaging between $300/rod and $880/rod, the landowner’s appraiser, considering the property’s true highest and best use, could conclude to a significantly higher value: 113 Rods x $500 per rod = $56,000 Given the foregoing example, it seems manifestly unreasonable for a utility company to consider only the ATF value when it is purchasing an easement and then turn around and sell or lease the same easement, based on its true highest and best use, for an exponential profit. § 1.08. Arguments Against Corridor Valuation Theory. [1] Corridor Transactions Are Inadmissible Data. The traditional rule in Texas has long been that market data involving entities with the power of eminent domain are legally inadmissible to determine just compensation, because such transactions are not arms-length as a matter of law.40 There are obvious inequities raised when a utility company is allowed to take using one valuation method and sell based on another. This fact, considered along with the rationale behind the prohibition against sales involving condemnors, leads the authors to believe that a good faith argument exists for the extension of the existing law. [a] Does The Existing Rule Make Sense Here? The Texas prohibition against using transactions involving condemning entities really arose in the context of appraisers using sales to condemning entities as opposed to from them. As one court stated: The reason for excluding proof of such sales is that they do not meet the willing seller-willing buyer concept; they are made under a direct or an implied threat of condemnation and, theoretically at least, are not free and voluntary.41 Applied in that context, the rule makes perfect sense. But what about when a condemnor is advertising to sell right-of-way, or the right to use right-of-way? Potential purchasers are not compelled to buy at that condemnor’s price; they can condemn their own right-of-way elsewhere or purchase from some other supplier. It seems logical that a meeting of the minds has occurred when a purchaser acquires rights for an advertised price, and that such sales (or leases) constitute competent market evidence, regardless of whether one or both parties to the transaction possess the power of eminent domain. [b] Bauer v. Lavaca-Navidad River Authority At least one Texas case indicates that if a landowner demonstrates that the highest and best use of desired property is for an easement corridor, then corridor sales are appropriate data to consider in the appraisal problem.42 In Bauer, the River Authority sought to condemn a 50’ wide water line easement across Bauer’s property. The location of the desired easement was in the midst of an established, 432’ wide "easement corridor" containing eight other easements previously granted to various oil companies and electric utilities. The court held that Bauer should have been permitted at trial to prove that the highest and best use of his property was for an easement corridor. Further, the court found that sales of easement rights-of-way within such corridors were relevant and admissible, provided the sales did not involve entities with the power of eminent domain. In the opinion, the court set out a guideline to determine when such evidence was proper: …[A]ppellant Bauer offered testimony that the highest and best use of the land in question was the sale of pipeline easements in his "pipeline corridor." He showed that the corridor was well-defined, and he offered testimony regarding the value of the condemned land by showing what he and his neighbor received for the sale of other pipeline easements to prior companies. … Bauer’s right to have the fact finder consider the land’s highest and best use in determining its market value was thus denied.43 The undisturbed holding of Bauer leaves open the right of Texas landowners to claim an easement corridor as highest and best use, and hints that sales from condemning entities of corridor rights-of-way may become fair game for an appraiser to consider when determining value for this property. [c] Other Support for Using Sales From Condemnors Other support, although limited, for the valid use of comparable market data involving public or quasi-public entities include various environmental groups and some right of way professionals. Their position calls "for the inclusion of a highest and best use for environmental preservation in a real estate appraisal based on comparable market data evidence. Some of the environmental value proponents argue for use of public agency comparable sales data, some for private sales data and some for both."44 In the state of California, where most of the debate over this issue originates, there is, in addition to prevailing case law, a provision in their evidence code which: (i) allows for a merger of the appraisal highest and best use of a property and the use for which a public entity is acquiring it; and (ii) allows use of prices paid by public agencies for open space as comparables for valuation purposes where such purchases were voluntary and not under the threat of condemnation.45 Certainly, the current argument against using market data involving a party having the power of eminent domain currently predominates. The inherent inequity of this rule in the context of corridor valuation, however, calls for modification of existing Texas law. Regardless, appraisers ought to acknowledge market reality. [2] The Condemnor Created the Value. Another argument commonly urged by condemnor utility companies is that they created the corridors through the original acquisition such that any future benefit would accrue to their rights of ownership. Consider the following example, though, that exposes the flaw in this logic. The State Highway Department builds a new freeway along the property line of Mr. Jones’ farm near the edge of town, creating valuable commercial frontage. A couple of years after completion, Wal-Mart comes along and wants to purchase Jones’ farm which now has frontage along a new freeway. Mr. Jones contributed no land nor any monies for the construction of the roadway. Should the value of his property be based on who assembled the right of way or who built the roadway? Obviously, once the road is built, future appraisals of Jones’ property would be based on its new highest and best use, without regard to who built the road. Likewise, when appraising property rights within a corridor, no consideration should be given to the creator of the corridor. [3] It’s Not a Corridor, It’s a Closet. The third emerging argument against corridor valuation is that usually the underlying property owner possesses only a small portion of the corridor and that value is only created when the whole corridor is assembled. Again, the value should be determined by analyzing market data such as the following (actual) transactions by a southeast Texas utility company: June 1993 to June 1998, 2-5 year options; 7.87 rods leased to a restaurant. For now, it is true that current law (in Texas anyway) discourages using sales between condemning entities as market data. The extremely active marketing efforts of power line and pipeline companies, however, coupled with increasing amounts of actual sales data point to corridor valuation for expansion of existing easements as the only logical way of conforming with the Uniform Standards of Appraisal Practice. Perhaps our Native American forebears had it right all along: Back in the days when agents representing a newly formed railroad were buying land for right of way they encountered some shrewd bargainers among the Indians. One Chief was asked whether he would sell a small eroded piece of land. "Sure, me sell for $50,000," said the Chief. "$50,000! Why that land is no good for planting or pasture. It is just no good for anything!" the agent exclaimed. The Chief grunted, "It heep good for railroad." 46
