In <br />looking at the Schirmer-Satre maps (notably ZC-4), at the extreme western edge of the map, west of <br />the Spring/30th interchange, their registration of the centerline of the R-o-W for 30th falls apart. At <br />the west edge of the map, their centerline is 124 feet north of the center of the black line denoting <br />30th Ave on the Metro Plan Diagram. This is due to an approximately 179-foot shift (in a direction of <br />N 58 W) of the layers containing the tax lots, City Limits, 30th Ave Centerline (as obtained by their <br />surveyors) and the UGB relative to the Metro Plan Zoning Diagram and the tax lots as they are <br />plotted according to LCOG. <br />This is, of course, in addition to the rotation issue, which partly allows them to slide everything to the <br />NW. They're using the fact that 30th Ave is not straight anywhere throughout the map cutout used by <br />them to fudge things. But they didn't cut the system off far enough east and a significant offset shows <br />up at that west edge... <br />The 179-foot shift to the NW moves the entire parcel N by approximately 95 feet and west by 151 feet <br />relative to the zoning map. The 95-foot northward shift, over the 4,490-ft E-W length of the parcel <br />accounts for 9.79 acres of reduction of POR, the rotation results in a reduction of 8.1 acres, and the <br />fact that the nearly N-S trending combined parcel boundary and UGB in the western portion of the <br />site slides west by 151 feet, makes up the rest of the 20-acre discrepancy we have between what <br />LCOG and the City's Parks and Open Space department came up with (around 40 acres) and what <br />Schirmer-Satre came up with (around 20 acres). <br />Nifty, eh? <br />Haven't heard back from Bill Clingman <br />Gunnar <br />Laurel Ridge Record (Z 15-5) Page 990 <br />
