(HWA) has performed a site exploration program, as well as geotechnical engineering analyses in support of the proposed rockery wall replacement located at the subject property in Everett, Washington. The approximate location of the project is shown in the Vicinity Map, Figure 1. Project Description It is our understanding that the existing terraced rockeries, located along your western property line, have deteriorated to the point that replacement of both rockeries is desirable. We understand that the City of Everett requires a geotechnical engineering evaluation and associated recommendations in order to issue a permit for rockery replacement. To facilitate the design of the proposed rockery replacement, HWA was tasked with evaluating the existing site soils at the wall location Site Description The project is located north of Mukilteo Boulevard and south of Madrona Avenue in Everett, Washington. The site consists of predominantly residential single-family homes. The existing residence is positioned into the hillside south of Madrona Avenue.
