The purpose of this report is to evaluate the steep slope on this property with regard to the proposed addition. Background: The subject property is located at 2325 Taylor Drive in Everett(parcel#00417000100202). It has been proposed to subdivide the subject parcel into two separate parcels by bisecting it in the east- west direction. After dividing the property, a new residence is planned to be constructed on the lot bordering Taylor Drive, whereas the planned development for the northern lot consists of remodels/additions that will enlarge the building footprint on the northern and southern sides of the existing house. A steep north-facing slope exists on the northern two-thirds of the subject property. The existing residence is at the top of the steep slope. Since this steep slope is considered a geologic hazard and is situated within 200 feet of the proposed developments, a geotechnical assessment is required by City of Everett per Everett Municipal Code(EMC)1 chapter 19.37.080(B)(1). Geological Overview: Geological mapping'indicates the presence of Quaternary transitional beds (Qtb)near the surface at the site of this property. Transitional beds typically consist of mostly thick beds of gray silt and fine to very fine sand, though some layers of sand to peaty sand and gravel may be present in the lower part of these formations. In terms of hardness,transitional beds generally 13705 Bel-Red Road •Bellevue,Washington 98005 Phone 425/649-8757 •Fax 425/649-8758
