Premier Storage Everett, LLC ES-2432 <br /> June 26, 2012 Page 4 <br /> Revised June 28, 2012 <br /> Geologically Hazardous Areas <br /> ESNW reviewed Everett Municipal Code (EMC) section 37.080 — Geologically Hazardous <br /> Areas. The slope located on the west side of the site contains gradient in excess of 40 percent <br /> and are on the order of 14 feet in height. <br /> Proposal <br /> Based on review of the current site layout, a small portion of the northwestern corner of building <br /> B will be about 18 - 20 feet from the top of the slope area. The remainder of the project will <br /> maintain a setback of at least 25 feet from the slope area. The current proposal would result in <br /> a setback for a small area located in the northwest portion of the site. This setback would result <br /> in a minimum horizontal setback of about 18 - 20 feet from the top of the slope which is greater <br /> than the slope height of about 14 feet. The current proposal includes constructing a fire lane <br /> along the west side of the project. <br /> Conclusion <br /> In our opinion, the current proposal as depicted on the site plan is acceptable from a <br /> geotechnical standpoint for the following reasons: <br /> 1. The proposed development will not create a hazard to the subject property, surrounding <br /> properties or rights-of-way, or erosion or sedimentation to off-site properties or bodies of water. <br /> Soil stability and drainage conditions will be improved by the current site layout along the west <br /> side of the project. <br /> 2. The proposal addresses the existing geological constraints of the site, including an <br /> assessment of soils and hydrology. While there is limited fill along the upper slope area, the <br /> proposal will improve the soil conditions within the project area and will improve drainage <br /> provisions. <br /> 3. The proposed method of construction will reduce erosion potential, landslide and seismic <br /> hazard potential, and will improve or not adversely affect the stability of slopes, by utilizing <br /> engineered fill and retaining walls. <br /> 4. The proposal uses construction techniques which minimize disruption of existing topography <br /> and natural vegetation. The proposal will maintain the maximum buffer from the top of the <br /> slope outside the area required to construct the fire access lane and associated retaining wall. <br /> 5. The proposal is consistent with the purposes and provisions of this chapter and mitigates any <br /> permitted impacts to critical areas in the vicinity of the proposal; <br /> 6. The proposal mitigates all impacts identified in the geotechnical letter or geotechnical report; <br /> Earth Solutions NW, LLC <br />
