changes. <br />is: <br /> <br />Thus the change in value caused by proximity to a landfill <br /> <br />Percent price change = <br /> <br />Average price in zone Average price in zone <br />far from landfill near landfill <br /> <br />Average price in zone far from landfill <br /> <br />The problem with this method is that it does not account for differences <br />in the characteristics of the houses sold. For example, if mostly smaller <br />houses near the landfill were sold, it would exaggerate the effect. If <br />houses further from the landfill had a style less in demand, it would <br />underestimate the effect. <br /> <br />The second method not used was the comparative neighborhood method. <br />In this method, the average price of houses sold in whole neighborhoods <br />near the landfill were examined and compared to whole neighborhoods 2 <br />or more miles away. The problem here is similar to that above, except <br />it is compounded by the lack of discrete distance measurements. <br />The third method is the appraiser-based method. In this method, the <br />appraised price of the property by the County Assessor is used instead <br />of sales data. This allows evaluation of properties for which recent <br />sales data is not available. <br /> <br />Peer reviewers were unanimous in not wanting to rely on assessor estimates <br />unless sufficient data from other sources was unavailable. Since adequate <br />sample sizes from all but Oak Grove were available, this method was not <br />employed. <br /> <br />Once it was determined that these methods would be used in research, <br />a panel of Peer Reviewers were assembled to review methods, confirm <br />the validity of proposed modifications to research methods, and comment <br />on progress and findings. Panel members were selected by research <br />consultants conducting the study. They conferred by letter and were <br />paid for their independent review. The following published scientists <br />were on the Peer Review Panel: <br /> <br /> Joseph Havilecek, Ph.D., Economics, Ohio State University. <br /> Dr. Havilecek pioneered landfill-based property value impact <br /> research in the early 1970's with a study of five landfills in <br /> Indiana. <br /> <br /> · J. Walter Milon, Ph.D., Economics, University of Florida. <br /> Dr. Milon's expertise for this project is in statistical manipulation <br /> of property value data. <br /> <br /> · Arthur C.
