December 14, 2020 <br />Page 5 of 6 <br />Limited Geologic Evaluation <br />6. The proposal mitigates all impacts identified in the geotechnical letter or geotechnical report; <br />7. All utilities and access roads or driveways to and within the site are located so as to require <br />the minimum amount of modification to slopes, vegetation or geologically hazardous areas; and <br />8. The improvements are certified as safe as designed and under anticipated conditions by <br />a geologist. <br />The proposed landscaping work is considered `certified' as safe provided the following conditions <br />are utilized/implemented as part of development: <br />• Proper erosion control measures until final landscaping is in place <br />• All stockpile fill is removed or used as compacted structural fill behind new walls near the <br />east property line <br />• Permanent slopes have magnitudes of 2.5H:1V in areas affected by the recent and <br />proposed grading <br />• All runoff is controlled on site during construction <br />Conclusions & Recommendations <br />It is our opinion that the proposed landscaping work can be completed in a safe manner without <br />affected geologic hazards on the site or adjacent areas. The site and nearby steep slopes are stable <br />at this time with no evidence of historic or recent landslide activity or soil erosion. If there are <br />cleared areas resulting from construction, they should be re -surfaced with landscaping materials <br />and vegetation upon completion of the project. <br />The proposed construction should not adversely affect slope stability within the site and adjacent <br />areas provided the work is performed in accordance with our recommendations, permit <br />requirements, and adequate erosion control measures are put in place prior to construction. All <br />temporary and permanent runoff must be controlled and directed away from the steep slope <br />areas. <br />Closure <br />The information presented herein is based upon professional interpretation utilizing standard <br />practices and a degree of conservatism deemed proper for this project. We emphasize that this <br />report is valid for this project as outlined above and for the current site conditions and should not <br />be used for any other site. <br />www.cobaltgeo.com (2o6) 331-1097 <br />
