The decision of the BTA is affirmed.
Trebmal’s appeal challenges the land valuations for 1988 and 1989 and the building valuation for 1989. Trebmal also contends that the land and building values for 1989 constitute an unconstitutional taking of property without due process of law; that the BTA abused its discretion in violation of the uniform applicability provision of the Ohio Constitution, Section 26, Article II; and that the BTA decision constitutes a denial of equal protection of the laws, as guaranteed by the Ohio and federal Constitutions.
Trebmal’s constitutional issues are without merit. The valuation found by the BTA was not “grossly excessive,” as asserted by Trebmal, but was supported by credible evidence. The valuation did not constitute an unlawful taking of property in violation of the Fifth Amendment to the Constitution of the United States, or a denial of due process under the Fourteenth Amendment to the Constitution of the United States, or a violation of the Ohio Constitution.
In R.R.Z. Assoc. v. Cuyahoga Cty. Bd. of Revision (1988), 38 Ohio St.3d 198, 202, 527 N.E.2d 874, 878, we rejected appellant’s (R.R.Z. Associates’) claim that the subject property was not valued uniformly under Section 2, Article XII of the Ohio Constitution, stating: “[SJince we find that there is sufficient probative evidence to support the BTA’s decision, we disagree with appellant’s premise and hold that the property is valued uniformly.”
In Rick Case Motors, Inc. v. Tracy (1994), 71 Ohio St.3d 380, 382-383, 643 N.E.2d 1137, 1138, we stated:
“Finally, Case claims that this application of the statute denies it equal protection. It then recites examples of how this problem could occur; however, Case presented no evidence of how other taxpayers were actually treated in contrast with it. Consequently, the record is not factually sufficient to establish its claim. Lyons v. Limbach (1988), 40 Ohio St.3d 92, 94, 532 N.E.2d 106, 109.” See, also, Koblenz v. Cuyahoga Cty. Bd. of Revision (1966), 5 Ohio St.2d 214, 34 O.O.2d 424, 215 N.E.2d 384.
Trebmal can find no support in Allegheny Pittsburgh Coal Co. v. Cty. Comm. of Webster Cty. (1989), 488 U.S. 336, 109 S.Ct. 633, 102 L.Ed.2d 688. That case is factually distinguishable because, as the school board observes, in Allegheny, the Supreme Court was presented with the question whether certain tax assessments constituted an equal protection violation when the assessments were up to thirty-five times more than the assessments for comparable neighboring property over a ten-year period. See 488 U.S. at 342, 344, 109 S.Ct. at 637, 638, 102 L.Ed.2d at 696, 697.
Trebmal presented no evidence to establish that its property was assessed at a value that was “greatly in excess of the prevailing average ratio of assessed value *34to the fair market value * * * [of] property in Cuyahoga County.” Koblenz, supra, at 215, 34 O.O.2d at 424, 215 N.E.2d at 386.
In its cross-appeal, the school board contends that the BTA erred in not excluding the report and testimony of Trebmal’s expert witness, and that the BTA’s determination of value as to land and buildings was unreasonable and unlawful because it was based upon evidence which should have been excluded. The school board also contends the BTA’s decision should be reversed and remanded because it failed to impose monetary sanctions against Trebmal.
Taking the cross-appeal first, we agree with the BTA as to the request for sanctions. Apparently, Trebmal had intended to present the testimony of its officers to the BTA and had so advised the school board. The hearing was continued three times at Trebmal’s request because its witness was unavailable. However, on February 15, 1993, Trebmal changed its tactics and decided to present the appraisal evidence of Wesley Baker, and advised the school board of this change. Baker’s appraisal report was not available until the morning of the hearing, which was held on February 24, 1993. At the hearing, the school board moved for sanctions against Trebmal, seeking reimbursement of its costs incurred in opposing appellant’s original strategy and in challenging Baker’s appraisal.
Ohio Adm.Code 5717-1-10(A) states: “Discovery may be permitted by deposition upon oral examination or written questions; written interrogatories; * * * and requests for admissions. The ‘Ohio Rules of Civil Procedure’ shall be used as a guideline for discovery purposes * * The school board contends that the late notice of Trebmal’s intention to present an expert witness constituted “surprise.”
Although Civ.R. 37(B) provides for sanctions when a party fails to comply with discovery rules, the BTA found that there were other sanctions available to it, under Ohio Adm.Code 5717-1-13, which include prohibiting the introduction of expert testimony into evidence and ordering the payment of reasonable expenses caused by failure to obey an order. The BTA found, and we agree, that such sanctions were not appropriate because the school board was given a choice to cross-examine the appraiser at the hearing or to continue the hearing until a later time. In addition, the school board was prepared to, and did, in fact, offer the testimony of its own expert appraiser. Moreover, counsel for the school board was familiar with the underlying information and was able to cross-examine Trebmal’s appraisal witness effectively.
As to the true value of the subject property, we hold that the decision of the BTA was reasonable and lawful under paragraph four of the syllabus of Cardinal Fed. S. & L. Assn. v. Cuyahoga Cty. Bd. of Revision (1975), 44 Ohio St.2d 13, 73 O.O.2d 83, 336 N.E.2d 433:
*35“The fair market value of property for tax purposes is a question of fact, the determination of which is primarily within the province of the taxing authorities, and this court will not disturb a decision of the Board of Tax Appeals with respect to such valuation unless it affirmatively appears from the record that such decision is unreasonable or unlawful. (Bd. of Revision v. Fodor, 15 Ohio St.2d 52 [44 O.O.2d 30, 239 N.E.2d 25], approved and followed.)”
We are satisfied from our review of the record that the BTA’s findings are based upon sufficient probative evidence, including expert appraisal testimony. See First Union Real Estate Equity & Mgte. Investments v. Cuyahoga Cty. Bd. of Revision (1990), 53 Ohio St.3d 236, 560 N.E.2d 177.
Both Wesley Baker and Richard Van Curen, the school board’s appraisal witness, agreed that the highest and best use of the property was for office development and they utilized the same method of appraisal, the cost method, which the BTA found to be the most appropriate here. The BTA also agreed with Van Curen’s estimate of land value of $200,000 per acre as of January 1, 1988, and that that value should apply as well to 1989. Despite Baker’s conclusion that the reasonable value of the land was $150,000 per acre, the record discloses a forty-acre sale in the area in July 1988 for $180,000 per acre, and a six-acre sale of land with freeway exposure in July 1988 for $237,500 per acre. In addition, the BTA found Van Curen’s estimate of $220,000 per acre as of January 1, 1989 was not inconsistent with its finding because it was appropriate to carry forward the 1988 values to 1989.
Finally, Trebmal argues that the BTA ignored the zoning requirement that all tracts be at least six acres in size, and that this led to an excessive valuation for the land by the BTA. This issue is not dispositive because Wesley testified that the 4.593-acre tract could have been made to comply with zoning requirements, either by acquiring adjoining land (albeit with difficulty) to enlarge the tract to six full acres, or by selling the tract. In any case, there was sufficient evidence to establish that the BTA determination of $200,000 per acre was not unreasonable or unlawful, and thus its decision is affirmed.
Decision affirmed.
