OPINION OF THE COURT
A party who claims relief for injury to real property need establish the amount of damages under only one measure, although other measures may be applicable. Damages, however, must be established under at least one measure.
Plaintiffs and defendants owned adjoining lots partly separated by a small pond jointly owned and used by them. In fall, 1975, defendants purchased landfill for spreading on their property as part of a landscaping project. Water flowing from a culvert washed a large quantity of the fill material into the pond, discoloring the water and effectively preventing its use during the summer of 1976. A number of trees planted by plaintiffs on both parties’ properties were also destroyed. Defendants eventually hired a contractor to compact the fill properly. The pond cleared and was again usable by summer, 1977, although there remained some residual silt damage that would not dissipate for several more years.
Plaintiffs brought suit to recover for the cost of removing the silt from the pond, the replacement cost of the destroyed trees, and the loss of use of the pond. After a trial without jury, plaintiffs obtained a judgment for $6,950 to cover the cost of removing the silt and nominal damages of $1 for loss of use of the pond. The trial court denied recovery for the trees on the ground that there was insufficient proof.
Both parties appealed. The Appellate Division affirmed the award for restoring the pond. It found, however, that there was sufficient evidence to support plaintiffs’ claim for loss of 12 trees and awarded $2,160 for their replacement.
Defendants first attack the award for the cost of removing the silt. Referring to the long-established rule that the proper measure of damages for permanent injury to real property is the lesser of the decline in market value and the cost of restoration (see Hartshorn v Chaddock,
The nature of the claim that a different measure of damages would yield a lesser award raises a question somewhat akin to mitigation of damages or avoidable consequences; i.e., is the plaintiff receiving no more than is reasonably necessary to remedy fully the injury while avoiding uneconomical efforts. As a “mitigation” issue, the burden falls upon the defendant to prove that a lesser amount than that claimed by plaintiff will sufficiently compensate for the loss (cf. People’s Gas & Elec. Co. of Oswego v State of New York,
Plaintiffs here met their obligation to provide evidence of the amount of the injury. That they did not prove their
The remainder of the Appellate Division’s order increasing the award for plaintiffs’ other claimed injuries was incorrect, however. The Appellate Division erred in awarding to plaintiffs the replacement cost of the trees. A careful reading of the record reveals that plaintiffs were never able to state the precise number of trees that were present on their property and destroyed by the siltage. Inasmuch as recovery for this loss would necessarily be predicated on speculation, the Appellate Division’s award must be reversed.
Finally, awarding $500 for loss of the pond’s use is unsupported by the evidence. Recovery for temporary injury to real property may be measured by the value of the loss of use, which is determined by the decrease in the property’s rental value during the pendency of the injury (see Reisert v City of New York,
