I Immediately south of that dotted line is a wavy line that depicts the UGB. Like <br />2 the Metro Plan Diagrams, the location of the UGB line depicted on the 1982 <br />3 refinement map is approximate, since the UGB line location in this area was <br />4 not precisely determined until 2007. A portion of East 30th Avenue is depicted <br />5 in the southwestern corner of the refinement map. The UGB line has several <br />6 curves similar to those shown on the 2004 Metro Plan Diagram, but at its <br />7 western end does not appear to dip as sharply south as on the 2004 Metro Plan <br />8 Diagram, or as depicted on the 2007 annexation map. <br />9 South of the UGB line, outside the plan area, the refinement plan map is <br />10 blank and nothing is depicted. North of the two lines, inside the plan area, the <br />11 map shows three types of land use designations, using shaded and hatched <br />12 markings: Low Density Residential, Medium Density Residential, and <br />13 Commercial. The area immediately north of the two lines representing the plan <br />14 area boundary and the UGB is shaded to represent the Low Density Residential <br />15 plan designation. The 1982 refinement map does not depict the Parks and Open <br />16 Spaces plan designation anywhere within or without the plan area. Petitioners <br />17 argued to the city that the Laurel Hill Refinement Plan map indicates the city's <br />18 intent to designate as LDR all lands north of the UGB in this area, and to <br />19 designate as POS no lands north of the UGB in this area. <br />20 D. The City's Decision <br />21 The hearings officer concluded that 2004 Metro Plan Diagram <br />22 unambiguously designates some portion of the subject property POS, and <br />23 rejected petitioners' reliance on the 1982 Laurel Hill Refinement Plan map as <br />24 support for petitioners' claim that no part of the subject property is designated <br />Page 9 <br />Laurel Ridge Record (Z 15-5) Page 1047 <br />
