GEOTECHNICAL REPORT GEOTECHNICAL RECOMMENDATIONS & GEOLOGICALLY HAZARDOUS AREAS ASSESSMENT Proposed Parking Garage and Surface Parking Saint Edward Seminary Kenmore, Washington PROJECT NO. 16-163 June 2016 Prepared for: Daniels Real Estate Geotechnical & Earthquake Engineering Consultants Geotechnical & Earthquake Engineering Consultants June 29, 2016 PanGEO Project No. 16-163 Ms. Trevina Wang Daniels Real Estate 2401 Utah Avenue South, Suite 305 Seattle, WA 98134 Subject: GEOTECHNICAL REPORT GEOTECHNICAL RECOMMENDATIONS & GEOLOGICALLY HAZARDOUS AREAS ASSESSMENT Proposed Parking Garage and Surface Parking Saint Edward Seminary 14445 Juanita Drive NE, Kenmore, Washington Dear Ms. Wang: As requested, PanGEO, Inc. is pleased to present the attached report to assist the project team with the design and construction of the proposed parking garage and surface parking adjacent to the Saint Edward Seminary in Kenmore, Washington. In preparing this report, we completed 11 test borings to evaluate the subsurface conditions, conducted a reconnaissance of the geologic hazards at the site, conducted laboratory testing, performed our engineering analysis, and prepared this report. Based the results of our study, the site is underlain by glacially consolidated clay, silt, and silty sand with gravel. In our opinion, the proposed parking garage can be supported on conventional spread footings. Saint Edward Park contains areas mapped by the City of Kenmore as geologic hazard areas due to erosion and landslide hazards. Based on our review of the City’s mapping and a reconnaissance of the study area, it appears the planned improvements are located more than 150 feet from the mapped geologic hazards. As such, in our opinion, provided that the surface water will be properly managed, the potential for the planned improvements to affect these geologically hazardous areas is minimal.
