r SHANNON F�WILSON,INC. Iactions such as dumping water, which can cause accclerated erosion of the hillside. These ffactors should be recognized. In our opinion, it is in the avner's best interest to approach the City aad d�nvnslope property owner regarding these concems. The City and the dawnslope avnec should be made awue of such wncerns. The adjacent awner may wish w � take precautions to protect any futune faciliries at the davnslope site from soil movement on I the slope. These measures could include providing adequace setbacks from the toe of the slope and constructing a berm to act as a buffer against sliding, among others. Such measures wene beyond the scope of our study. Finally, the owner should consider a readjustment of the curnent east property line ftnm its Iacisdng location. In our opinion, it is logical to readjust the property line to the top of the slope and have the dawnslope owner eztend his property co the top. Because the InUawest I Seaway site will rest on glacial, till-like soils, there is little risk of the adjacent owner's ac6ons affec6ng your site. Additionally, the slope will not be visible from the top and may I be neglectecl by the upslope tenant, while the downslope owner can observe any signs of instability and correct them as required. I8.4 �it rdding and S�berade Prep�ration I8.4.1 General � Site grading, as described in this report, includes all excavations and fills necessary to bring the site to the proposed elevadons, including excavation and fill to support building foundations, slab-on-grade floors and pavemenu, and backfill for foundations. The nadve soils at the project site wntain suf6cient amounts of silt and clay to � produce a cohesive mizture when wet. Such soils are highly :uscepdble to changes in water content and become soft and difficult to handle when wet. Proof-mlling and wmpacdon Imay become difficult or impossible when the moisture content of these soils acceeds their opdmum moisture content. It is generally not feasible to dry out such soils during wet � weather periods. 1Yeatment with cement or other addipves is an option; however, it will add cost to the projecL Therefore, we recommend that site grading and earthwvrk be � performed during the drier, warmer months of the year (generally June through September). Based on our experience on similar sites, it is our opinion that �nificant incre?ces in c�sL f W-6693-01 14
