The purpose of my visit was to make a reconnaissance level assessment of slope stability/landslide risk issues, associated with a proposed replacement decks (or the existing residence. This letter is a summary of my observations and our discussions, and is intended to highlight general areas of my observations. SITE CONDITIONS The site is located in the western part o1 Everett on a ridge east of Merrill & Ring Creek. Specifically, the lot is at the top of the west facing siope into the Merri!I & Ring Creek valley. City of Everett Critical Areas IAapping identifies th� slope descending into the valley as a Medium to High Erosion and High to Very Fligh Landslide Critical Areas. The portion of the site east of the top of the slope (between the stn�et and the top of the steep slope) has been developed in a conventional suburban man�er. Tt�e slope area is in a quasi-natural state, vegetated with a mix of conifer and deciduous tree:; and associated underbrush. My observations of the vegetation and landforms on the slope as viewed from the top of the slope suggest the typical quasi- stable/quasi-unstable conditions of the Me�rill 8 Riny Creek valley siopes. The existing residenlial struclure is built into ;he upper portion of the slope with the highest surrounding ground in the southeast corner of the house (garage area) and the lowest at the northwest corner. The rear (west side) of the house is set back from the top of the steep slope various distances, depending on the specific location on the structure. The northwest corner of the structure is at the closest approach to the steep siope. There appears to be a minor indentation of the steep slope near the north property line and on the adjacent property to the
