Eugene Hearings Official <br />October 12, 2016 <br />Page 5 <br />(b) The survey data are precise in the real world. Only the applicant has submitted <br />survey data. <br />Survey data are now available for the boundaries of the subject property and the <br />following real world features tied to the subject property: Centerline of E. 301h Ave.; the <br />centerline of Spring Blvd.; the boundaries of TL 301 - the green finger; the east boundary <br />of TL 500; and the west, north and east boundaries of TL 800 - Bloomberg Park. All <br />these data are shown on a single survey map by Branch Engineering, submitted at the <br />hearing. <br />The Applicant's September 21 hearing submittal also included four large sheets, each <br />fitting the survey of the subject property to one of four surveyed referents - the center <br />line of 301h Ave., the green finger, Spring Blvd, and Bloomberg Park. <br />Survey data are available for only one proposed location of the plan boundary line. That <br />is the line proposed by the applicant and approved in the previous decision. <br />(c) The GIS data, notably county tax lot data and the city limits line, are not precise in the <br />real world. By definition these data sets are all approximations. Every source of GIS data that <br />was used by the City or the opponents is a database that comes with substantially the same <br />disclaimer about limitations on its accuracy and use. See verbatim disclaimers, quoted in the <br />Schirmer Satre October 5 letter, from the City, the County, LCOG, and RLID. LCOG says: <br />"The relative accuracy and absolute accuracy of this product are not guaranteed * * * The <br />County says about its tax lot maps: "Current configurations and/or designations for specific <br />parcels should always be confirmed with the appropriate jurisdiction(s)." The City says: "the <br />maps and data are dynamic and in a constant state of maintenance, correction and revision. Any <br />maps and associated data for access do not represent a survey." <br />The inherent limitations of the GIS data and shortcomings in the opponents' and staff's <br />use of GIS data are now well documented in the Record. See especially the Schirmer <br />Satre September 28 open record submittal, and the Schirmer Satre October 5 rebuttal <br />evidence. <br />4. Discussion. <br />The Hearings Official must choose a methodology to locate the boundary line, and then he must <br />actually locate the line. <br />Choosing a methodology: The applicant's methodology uses all survey data for <br />referents on the Diagram. The opponents use only imprecise GIS data for referents on the <br />Diagram and other stuff not on the Diagram. <br />Neither methodology allows simultaneous matching of multiple referents on the Metro Plan <br />Diagram to the subject property. The Applicant showed this for the surveyed referents in its <br />
