� DAVID L. NELSON AND ASSOCIATES, INC. "� Consulting Engineering Geology � October 6, 1992 Project No. 9892 � Page 2 � All elevations mentioned in this report refer to existing qrade. We were provided by you with a site plan of the lot araa, which was used for preparation of our Location Map. We did discuss with you on site the proposed residence placement area, based � upon desired building setbacks. Locations and observed conditions are graphically shown on the � enclosed Location Map (sheet M-1 ) and Slope Profile (sheet M-2 ) . i � ERISTING CONDITIONS � � The site consists of about 2.5 acres located just of 46th Street SW, at about the 300 Dlock, in the City of Everett, Wa�hington. The proposed residence development area consists of a small, I westerly part of the lot; whereas, the majority of the lot consists of a steep easterly facing slope, which ends along Pigeon Creek �1. ' Presently, the site is undeveloped, but sho�os signs of some past clearing, yrading and filling within the proposed development area. Vegetation on the site consists primarily of grass and a ffew trees along the top of slope within tlie upslope portion. Mixed deciduous trees, evergreen trees and underbrush occur within the sloping portion of the lot, and off-site to the north � and north withinsthe upslopeparea1oPAstopWofgslope tlinee occurs at a point about as shown on the Location Map, which crosses the � site in an undulating fashion, qenerally from southwest to ;iortheast. Below this top of slope, the sloping portion is steep to very steep down generally to the east. The proposed residence is planned to be above the top of slope. A cross section showing I the top of slope and the underlying soil conditions are presented on Sheet M-2. IGealogic Conditions Landforms within this region comprise a system of glacially sculptect features, which have been exposed by post-glacial I erosion. Locally, the terrain of this area are interpreted to have been glacially modified, and to have been placed during the latest and next to latest glaciation of the Puget Lowland area. �t Subsequent erosion by drainages such as Pigeon Creek #1 have created local steep slope areas within these deposits. Glacial ice is thought to have last occupied the region during the late � The1latesteqlacial adva;ice�r�ivertthe3ar�ea isareferr�detorasethe Vashon Stade of the Frarez Glaciation. Evidence of at least three (3) glaciations have been recorded in this portion of the � city of Everett. � l � __
