Among other recommendations, <br />5 the Geotechnical Investigation recommended that within the "exclusion area" <br />6 specific building foundation plans "should be reviewed on a case by case basis <br />7 by qualified professionals prior to design and construction." Record 4758. As <br />8 discussed below, the hearings official and planning commission ultimately <br />9 found compliance with EC 9.8320(6) and EC 9.9630(3)(c), but based on the <br />10 recommendation of the city public works department also imposed Condition of <br />11 Approval 10, which requires that any application to construct public <br />12 improvements or for a building permit include a geotechnical analysis by a <br />13 certified engineer. We quote Condition of Approval 10, as modified by the <br />14 planning commission, below. <br />15 The Neighbors' geotechnical consultant criticized the Geotechnical <br />16 Investigation on a number of grounds, including the number and location of the <br />17 test pits, arguing that the test pits were concentrated on the gentler slopes near <br />18 the ridgeline and not located on the steeper portions of the property, or near the <br />19 two identified slide areas. The consultant argued that the Geotechnical <br />20 Investigation was therefore incomplete and essentially recommended deferring <br />21 site-specific analysis to the building permit stage. For these reasons among <br />22 others the geotechnical consultant argued that the Geotechnical Investigation <br />Page 34 <br />
