DEPARTMENT OF TRANSPORTATION
v.
Frank BRAGG and wife, Jo Anne Bragg; Orville D. Coward, Trustee; and Don D. Cogdill and Clem H. Cogdill.
No. 670PA82.
Supreme Court of North Carolina.
May 3, 1983.
*228 Rufus L. Edmisten, Atty. Gen. by Eugene A. Smith, Sr. Deputy Atty. Gen., Raleigh, and Frank P. Graham, Asst. Atty. Gen., Asheville, for plaintiff-appellee.
Coward, Coward & Dillard, Sylvia and Brown, Ward, Haynes & Griffin by H.S. Ward, Jr., Waynesville, for defendants-appellants.
MARTIN, Justice.
The sole question presented for review is whether Judge Sitton erred in granting plaintiff's pretrial motion to exclude from trial evidence of injury and damage to the remainder of defendants' property which occurred after the Department of Transportation condemned part of the tract. This question concerns the elements of damages which should be considered in determining the amount of compensation to be paid the landowners. We hold that it was error to grant the motion and thus reverse the decision of the Court of Appeals and remand for further proceedings not inconsistent with this opinion.
*229 On 28 March 1978, the Department of Transportation filed a complaint condemning part of defendants' property for the purpose of widening U.S. Highway 441. By N.C.G.S. 136-104 this filing had the effect of immediately vesting title to and right of possession of the property in the Department of Transportation. After 28 March 1978, the Department began widening and improving a section of Highway 441 adjacent to defendants' land. In the process the Department caused surface and subsurface water from a spring formerly originating to the west of the highway to drain in a new course running under defendants' motel and then into Shoal Creek. In a motion in limine, plaintiff sought to prevent the introduction at trial of evidence of the new drainage pattern and the injury it caused to defendants' remaining property. The trial court ruled that this evidence was inadmissible. We hold that this ruling was error.
Evidence of damage caused by the alleged water diversion is relevant to a determination of the amount of just compensation due for the taking of the property described in the 28 March 1978 complaint. When the Department of Transportation condemns only part of a tract of land, the owners of the land are entitled to receive the difference between the fair market value of the entire tract immediately before the taking and the fair market value of the remaining property after the taking, less any general and special benefits. N.C.Gen. Stat. § 136-112(1) (1981). See also, e.g., Charlotte v. Recreation Comm., 278 N.C. 26, 178 S.E.2d 601 (1971); Gallimore v. Highway Comm., 241 N.C. 350, 85 S.E.2d 392 (1955); Power Co. v. Hayes, 193 N.C. 104, 136 S.E. 353 (1927). See generally Power Co. v. Winebarger, 300 N.C. 57, 265 S.E.2d 227 (1980); Nichols, 4A Eminent Domain §§ 14.01-.02 (1981). In determining the fair market value of the remaining property, the owner is entitled to recover compensation for any damage caused to the remainder as a result of the condemnor's use of the appropriated portion. Board of Transportation v. Warehouse Corp., 300 N.C. 700, 268 S.E.2d 180 (1980); Light Company v. Creasman, 262 N.C. 390, 137 S.E.2d 497 (1964); Highway Commission v. Black, 239 N.C. 198, 79 S.E.2d 778 (1954); Board of Transportation v. Brown, 34 N.C.App. 266, 237 S.E.2d 854 (1977), aff'd per curiam, 296 N.C. 250, 249 S.E.2d 803 (1978). That is, "[t]he fair market value of the remainder immediately after the taking contemplates the project in its completed state and any damage to the remainder due to the user [sic] to which the part appropriated may, or probably will, be put." Board of Transportation v. Brown, supra, 34 N.C.App. at 268, 237 S.E.2d at 855 (emphasis ours).
In Board of Transportation v. Warehouse Corp., supra, this Court was concerned with what elements of damages could be considered by the jury in determining just compensation to be paid the landowner. One such element was water damage to the landowner's remaining property caused by the diversion of Gashes Creek after the date of taking. Although the Court was principally deciding whether the reasonable use rule of surface water drainage, adopted in Pendergrast v. Aiken, 293 N.C. 201, 236 S.E.2d 787 (1977), was applicable to condemnation proceedings, it held:
It follows, therefore, "that a body possessing the right to exercise the power of eminent domain is required to make compensation for damages to land not taken resulting from the obstruction or diversion of, or other interference with, the natural flow of surface water, by a public improvement, although a private landowner would not be liable in damages under the same circumstances, upon the ground that such obstruction, diversion, or interference is a taking or damaging of such land within the meaning of a constitutional provision requiring compensation to be made on the taking or damaging of private property for public use."
300 N.C. at 706, 268 S.E.2d at 184 (citations omitted). In Warehouse Corp., the jury was allowed to consider as an element of just compensation damage to the landowner's remaining property caused by the diversion of water occurring after the taking. *230 Therefore, we hold that when the Department of Transportation takes only a part of a tract of land, the owners may introduce at the jury trial on the issue of compensation any evidence of damage to the remaining property caused by the Department of Transportation before the opening of the jury trial. Here, defendants were entitled to show any damage to their remaining property caused by plaintiff's diversion of water during the construction of the highway project prior to trial. Id.
If the jury finds that the injury is permanent in nature, plaintiff would acquire a permanent drainage easement over the property of defendants.[1] If the jury finds that the injury is not permanent, defendants would be entitled to be compensated for the taking of a temporary drainage easement. In determining the amount of damages which defendants may be entitled to recover for the alleged water diversion as a part of just compensation, evidence of the "cost to cure" the water diversion would be competent. Cf. Nichols, 4A Eminent Domain § 14.04 (1981); 27 Am.Jur.2d Eminent Domain § 314 (1966).
For reasons stated above, the decision of the Court of Appeals is reversed and the case is remanded to the superior court for further proceedings.
REVERSED AND REMANDED.
NOTES
[1]  In this respect the evidence disallowed below would have been competent to show that, in effect, the Department of Transportation had inversely condemned a permanent drainage easement not listed in its original complaint. See N.C.Gen.Stat. § 136-111 (1981). Cf. Board of Transportation v. Warehouse Corp., 300 N.C. 700, 268 S.E.2d 180 (1980); City of Kings Mountain v. Goforth, 283 N.C. 316, 196 S.E.2d 231 (1973). A property owner may initiate a proceeding to receive just compensation for inverse condemnation of his property by the Department of Transportation. N.C.Gen.Stat. § 136-111 (1981). However, when, as here, the Department has initiated a partial taking under N.C.G.S. 136-103 and trial on the issue of damages has not yet occurred, principles of judicial economy dictate that the owners of the taken land may allege a further taking by inverse condemnation in the ongoing proceedings.
