The EGR report estimates that the average thickness of the aggregate layer in that area is 70.5 feet; however, DOGAMI evaluation observed only 51.5 feet depth (see Exhibit 144). The Council also finds that EGR’s Exhibit A (e.g. p. 5- 8 and 11-13, Figures 7, 8, and 9, Appendix E well logs and table), and related materials, establish that there are two contiguous, but distinct, layers of sand and gravel, in the expansion area. These layers consist of an upper layer (“younger alluvium”) and a lower layer (“older alluvium”). The EGR report also acknowledges that layers of mudflow/clay from 4 to 12 fee thick have been experienced on the existing excavation site and are encountered along the pit wall (see also in Exhibit 1, EGR’s Exhibit A (e.g. p. 5- 8 and 11- 13, Figures 7, 8, and 9, and Boring Log of pit wall) and Exhibit 216). Based on that information, we also find that neither of these individual layers of aggregate is 60 feet thick. Therefore, OAR 660-023-180(3)(d)(B) applies. In summary, even if the proposed expansion site satisfied the significance criteria of OAR 660- 023-180(3)(a), because section (3)(d)(B) applies to the site, the site would not be significant. Goal 5 Conclusion. The City finds that, for the reasons stated above the application is inconsistent with Statewide Planning Goal 5. As such, there is no need or requirement that the City to provide further analysis. Ordinance - 12
