Subsurface Fxploration and 2026 Grand Avenue Georechnica(Engineering Report Everert Nashinqton Narrative Sratement - II. NARRATIVE STATEMENT 5.0 INTRODUCTON The following narrative statement is a geocechnical response to the criteria requested by the Ciry of Everett for evaluation of the project application. The City criteria is in italics followed by Associated Earth Sciences, Inc.'s (AESI's) response. ; I. The proposed development tivil! not create a l:a<.ard to the subject properry, surrounding ; properties ar rights-of-way, erosion or sedimentatia: to off-site propenies or 6odies of � water. The proposed developmen[ will likety require remporary or permanent shoring of excavation cuts. Our office should complete a shoring design once desien plans have been finalized. Shoring design will consider geotechnical hazards to existing property, adjacent properti;,s, and rights-of-a�ay. This report is considered preliminary since design plans and construction decails were not complered at the time of this report. We recommend that AESI perform a georechnical plan review of the design plans to ensure tha[ erosion or sedimentation �vill not �ccur on or adjacent to the property. ?. 77ie proposal addresses die existing g��ological catstruirus oj the site, ir:cG�ding as assessment of soils and hydrology. As discussed in Section [ of this report, the eeoloQy of the sire generally consists of loose fill soils overlying glacially consolidated advance ounvash sediments. Development of the site is geologically constrained by a steep bluff on the west, private properry on the soudi and north, and public right-of-way lucated on the eas[. As discussed in Section III of [his report, we recommend that the �restern half of the buildine be supported on a deep pile foundation due to the presence of loose fill and the proximiry of the steep bluff. In our opinion, founding of che �vest part of the building on piles will allow reduction of the top of the slope set back to 8 feet and mitigate the hazard posed by the steep slope. 3. 77�e proposed merhod of constn�crion xif! red«ce erosion potential, Imidslide and seisrnic ha�ard poteritial, aiid �vill inrprove or iiot adversely affect tlre stabiliry of slopes. , The construction of the building according to the recommendations included in tttis report and any subsequent recommenda[ions �vill not adversely affect tlie stability of siopes. Construction of the building will result in die removal of existing fill soils and �vill not require the import of till soils.
