GeoTest Services, Inc. <br />4320 Thomson Avenue, Everett, WA <br />I&L& = <br />Image 3: 2009 Aerial Photo. Taken from Google Earth. <br />April 12, 2019 <br />Project No. 19-0050 <br />1 <br />The 1990 aerial photo (Image 2) appears to indicate that land use within the subject <br />and adjacent properties has remained relatively unchanged within the last 28 years. <br />Since 1990, new single-family residences have been constructed upslope from the <br />subject property, and some vegetation has been removed from the slope. <br />There does not appear to be any noticeable signs of large-scale "global" instability on <br />or just west of the subject property, as observed in the reviewed aerial photos <br />spanning 28 years. Please note that the aerial photos may not fully depict actual <br />surface conditions due to the tree canopy and/or other vegetation possibly obscuring <br />the ground surface. <br />Bare Earth Imagery Review <br />GTS reviewed bare earth imagery of the site vicinity, subject property, and slope. <br />Based on a review of this imagery, there does not appear to be any visible indications <br />of tension cracks or large-scale head scarps associated with slope instability. Outside <br />of the general topographic profile of the slope, no signs of large scale "global" <br />instability on the subject property were observed in our bare earth imagery review. <br />Please note that not all signs of slope instability can be observed in the bare earth <br />imagery review due to imagery resolution and scale. In addition, any signs of instability <br />on the site slopes that have occurred within the last -5 years, if present, have occurred <br />after original imagery acquisition. <br />5 <br />
