In a condemnation proceeding, the defendant State of New York appeals and claimant cross-appeals from a judgment of the Court of Claims (Silverman, J.), dated August 14, 1987, and amended August 24, 1987, which, inter alia, awarded the claimant damages in the principal amount of $344,000.
Ordered that the judgment as amended is modified, on the law and on the facts, by increasing the award to the principal amount $377,300, representing the sum of $12,250 per acre for the 30.8 acres appropriated; as so modified the judgment as amended is affirmed, with costs to the claimant.
The evidence amply supports the determination that the highest and best use of the subject parcel, a property comprised largely of wetlands, would be a cluster-type development pursuant to Town Law § 281. The State of New York failed to establish the existence of any ordinance or regulation prohibiting the use of the wetlands for yield for the purpose of establishing an appropriate density under Town Law § 281. In the absence of any regulation or ordinance to the contrary, open land may be used in determining appropriate density, even if the open land itself cannot be built upon (see, Matter of Friends of Shawangunks v Knowlton, 64 NY2d 387, 394-395).
Nor was it proved that it was the policy of the Town of Brookhaven to prohibit the use of wetlands for yield purposes. Apart from the potential problems that might be presented by an uncodified policy, none was established here where no such Town Law § 281 application had ever been presented to or passed upon by the town.
We find, however, that the court erred in its calculation of the claimant’s damages. Prior to the taking, the claimant’s parcel consisted of approximately 32.5 acres of land, of which approximately 23 acres were considered tidal wetlands. The court properly found that the before value of the entire parcel was $398,000, or $12,250 per acre. By the instant condemnation, the State acquired all of the wetlands acreage and over seven acres of uplands, leaving claimant with approximately two acres of uplands still in its possession.
