I On all three maps, the two lines representing East 30th Avenue and the <br />2 UGB intersect. On the 1980 and 1987 maps, the UGB line in this area is a <br />3 fairly straight line, angling in a southwest direction from Interstate 5 for <br />4 approximately one mile and intersecting East 30th Avenue at something close to <br />5 a right angle. On the 1980 and 1987 maps, the UGB line passes through the <br />6 northerly portion of the POS plan designation, with most of the POS <br />7 designation south of the line, and only a very narrow band of green color <br />8 visible in the area north of the intersection of East 30th Avenue and the UGB. <br />9 In contrast to the two earlier maps, on the 2004 Metro Plan Diagram the <br />10 UGB line in this area has several significant curves in it, and in particular at its <br />11 -western end dips almost straight south before turning west to intersect the East <br />12 30th Avenue right-of-way. That dip and intersection form an inverted triangle <br />13 somewhat similar in shape to the one established in the 2007 annexation <br />14 decision.4 Also in contrast, on the 2004 Metro Plan Diagram the body of the <br />15 triangle north of the intersection of East 30th and the UGB line is colored <br />16 entirely green, representing the POS designation. At the one inch equals 7,000 <br />17 feet scale of the 2004 map, the north to south width of the POS designation in <br />18 the area of the triangle where it borders East 30th Avenue appears to be about <br />19 3/8ths of an inch, well over 1000 feet on the ground. South and southeast of <br />20 the apex of the triangle, outside the UGB, there is a relatively narrow area <br />4 Petitioners dispute that the 2007 annexation decision relied on the 2004 Metro Plan Diagram to determine <br />the precise location of the UGB line. That may be, but there is no possible dispute that the curves and general <br />shape of the 2007 UGB line established in the annexation decision resembles the curves and general shape of the <br />UGB line depicted in the 2004 Metro Plan Diagram. Compare Petition for Review Appendix 22 and Appendix <br />46. In particular, the southwest portion of both lines form the rough shape of an inverted triangle where the <br />UGB line dips south to intersect the East 30th Avenue right-of-way. The record does not reflect the explanation <br />for this similarity, but it is easy to speculate that the curves depicted on the 2004 Metro Plan Diagram were <br />intended to approximate the location of the ridgeline, based on more recent topographic data available since <br />1987. That could account for the resemblance, because the location of the ridgeline was one of the factors the <br />boundary commission considered in establishing the precise location of the UGB line. <br />Page 7 <br />Laurel Ridge Record (Z 15-5) Page 1045 <br />
