I 4.1, Develooment CondiHons Curcently, the northern half of the site is occupied by a pharmacy�nd a one-story medical office buiiding with a daylight basement enGosing an open-air courtyard. Asphalt-paved parking areas I lie north of the building and occupy the entire southem half of th�:: site, with access from two locations: one on the west from Kromer Avenue, and one on the north from Pacific Avenue. Concrete walkways surround the building and extend to Pacific Avenue at the north building I entrance. Underground utilities are located throughout the project site, along wilh above-ground utilities and overhead powerlines. I It is our understanding that the northern portion of the project site was previously occupied by a hotel structure built in the late nineteenth century. Because tum-of-the-century demolition projects I typically involved filling remnant basements with concrete fragments and discarded lumber, we anticipate that demolition debris associated with this previous development might still be present on the site. I4_2 Surface Conditions Surtace grades across the project site are gently sloping to the north/northwest, congruent with I regional topography. The entire southern half of the sitP is asphalt-paved, in addition to a small parking area north of the building and a fire lane to the east. The buiiding's northem and westem sides are landscaped with small to medium-sized trees and shrubs. A ravine exists on the south I edge of the site; its northern slopes are on the order of vertical to 1H:1V, and both slopes are heavily vegetated with groundcover. We did not observe evidence of recent landsliding along the ravine slopes. 4.3 Pavement Conditions The existing pavement appears to be in fair condition; no significant cracking or potholes were observed. Our exploratory borings revealad 1 Y:to 2 inches of asphalt concrete pavement over 2 to 3 inches of crushed rock. I 4_4 Soil Conditions According to United States Department of Agriculture maps of Snohomish County, on-site soils correspond to the Aldenvood soil type and to the hydrologic soil group 'C'. Published geologic maps of Snohomish County indicate that soil conditions in the site vicinity are characterized predominantly by glacially derived sediments deposited during the Vashon Stade of the Fraser Glaciation, known as Vashon till. � I5 avORDPROC`�9?PiqecislSeame�R000s�fP:]Ro��nsomPrcrdmce MrnO�Ro�wpC O I
