Mr. Erik Berg-Johansen <br />August 14, 2015 <br />Page 3 <br />Schirmer-Satre describe the process of the overlay as follows: <br />"Located the Subject Property on the Diagram. <br />❑ Obtained a drawing of the legal centerline of the 30th Avenue Right-of-Way from the project's surveyor. <br />Obtained updated edition of previously generated and field verified boundary survey of the subject property <br />with the 30th Avenue centerline added to the survey drawing. <br />❑ Generated a Zone Change "base sheet" utilizing the updated survey at a scale of 1" = 200'. The base sheet <br />contains the subject property boundary survey, the 30th Avenue right-of-way centerline and the eligible <br />"referents" of 30th Avenue and the north arrow. Printed this as Sheet No. ZC-2 - Zone Change - Subject <br />Property. <br />❑ As suggested by LUBA, enlarged the Metro Plan Diagram to the same scale as the property boundary <br />survey (1" = 200') and printed the Diagram (that portion in the vicinity of the subject property) on the base <br />sheet containing the subject property's boundary survey, 30th Avenue and the north arrow. <br />❑ Fit the location of the Metro Plan Diagram on the subject property by utilizing the Metro Plan Diagram <br />referents. Kept north oriented north, while aligning the Metro Plan Diagram's single black line <br />representation of 30th Avenue with the surveyor-located 30th Avenue centerline. Printed the Metro Plan <br />Diagram alone as Sheet No. ZC-3 - Zone Change - Adopted Metro Plan Diagram. Printed the Metro Plan <br />Diagram on top of the Subject Property as Sheet No. ZC-4." <br />Using this method, Schirmer-Satre obtain a total area of 20.47 acres of POS designation. This is <br />approximately half the area which has been reported to us by others, including the City of <br />Eugene's Parks and Open Space staff who indicated in a meeting held in 2014 for precisely this <br />purpose that their analysis showed that the Metro Plan Diagram indicated approximately 40 acres <br />of POS zoning designation on the Laurel Ridge PUD tax lots. <br />The Devil is in the Details - Even with North Arrows <br />Given the significant difference of approximately 20 acres of POS designation on Laurel Ridge <br />between the map version and methodology developed by Schirmer-Satre and the version <br />developed by LCOG and the City, the question looms as to the causes of this discrepancy. Both <br />maps cannot be "right". Given the fact that Schirmer-Satre felt the need to limit their method to <br />only two "referents", one of which (the North Arrow) is not even in the pertinent section of the map, <br />it appears that a likely problem is located in that methodology of registering the tax lot to the Metro <br />Plan Diagram. <br />Schirmer-Satre emphasizes that for their methodology, they obtained a hard copy of the original <br />Metro Plan Diagram adopted by the City of Eugene in 2004. A copy of this diagram is included in <br />the application as Exhibit C. However, the fact that the boundary lines on the site maps <br />accompanying the application (Exhibit G) are perfectly crisp indicates that it is likely that Schirmer- <br />Satre used the digital version of the Metro Plan Diagram available from LCOG, which is comprised <br />of GIS "layers". According to LCOG's disclaimer statement on the diagram, this version would <br />have also been used to create the hard copy in Exhibit C. <br />
