I respectfully dissent from the conclusion expressed in the majority opinion that the testimony of the aPpraiser, Bresnahan, was violative of the decision in Department of Highways v. Schulhoff, 167 Colo. 72, 445 P.2d 402. The Schulhoff case involved a tract of land slightly more than three quarters of an acre in size. As stated in the majority opinion, Schulhoffs appraisers were permitted to arrive at their opinions by hypothetically carving the tract into residential building sites, estimating the value of each site, and then adding the values of all sites.
