August 1, 2008 File No. 087-4 Peters Residence Page 2 Surface Conditions The subject property is located immediately southwest of the intersection of Federal Avenue and 42n, Street SE, in the Forest Park district of Everett, (see Figure 1). The property is bounded on the north by 42n° Avenue SE, on the south by the Mukilteo Boulevard right-cf-way, on the east by the extension of Federal Avenue, and on the west by residential property. The Peters residence is a single story wood framed structure with an attic bedroom and a full basement. The house was built in 1926, and was moved to its current location in 1959. The Peters purchased the house in 2003. Portions of the previously mentioned remodeling work are currently underway, (see attached photo plates). This portion of Everett is dominated by a broad north -south trending ridge feature. The eastern flank of the ridge descends down to Rucker Avenue, while the western flank descends into the Pigeon Creek drainage. The Peters property is situated atop the ridge, in a relatively level upland terrain, (see photo plates 1 and 2). Immediately south of the property, the alignment of Mukilteo Boulevard crosses the upper elevations of the ridge. In some areas, construction of the roadway has formed side -cuts and/or deepened previously existing topography. In this vicinity, construction of the road appears to have deepened a natural east -west trending gap in the ridge. Slopes The natural topography and road construction work have created a steep slope which extends from the road up to the south line of this property, (see Figure 2, and Photo plates 1. 2 and 3). While this slope does not extend onto this property, its proximity to the development area has caused concern to PCD staff, and has resulted in the requirement for this assessment. A survey line was run from the proposed addition area across the south yard and down to Mukilteo Boulevard. This is shown as slope section A - A' on Figure 2, and noted in the accompanying Photo plates. Surface measurements along the survey line were made using a Suunto clinometer and a 100 foot tape. A total slope height (vertical relief) of 23 feet was recorded along the survey line. A surface inclination of 37 degrees (about 75%) was recorded along the steep, upper approximate three-quarters of the slope. This steep upper segment accounts for about 16 feet of the total 23 foot slope height (vertical relief). The base of the slope flattens somewhat, and is fronted by a 4 foot high broken (stacked) concrete wall. The wall stands vertical and appears to be performing, (see Photo sequence 4 on Plate 3). The slope is vegetated with a number of large, mature evergreen and deciduous trees and scattered brush, (see Photo plates). A thin layer of forest litter and colluvium blankets the slope. Cal
