4 <br /> -12- 2P2/386/61-1 <br /> 2. Groundshaking -- Significant groundshaking may occur at the <br /> site which will require consideration in engineering evaluation <br /> of slope stability and structure design. <br /> 3 . Liquefaction -- Soils potentially susceptible to liquefaction <br /> are present but are expected to be limited in extent and capable of <br /> identification and definition. It appears likely that such deposits <br /> are at relatively shallow depth and accessible to remedial treatment <br /> `4` where performance may be critical. Elsewhere , such soils can be <br /> avoided or structure support achieved at greater depth. <br /> ^: 4 . Shallow groundwater -- General shallow groundwater conditions <br /> will have a significant impact on construction and design. Local <br /> de-watering is expected to be feasible for construction of indivi-• <br /> dual project elements. Mitigation for structure design could incluc; <br /> T; local grade raises and/or subdrainage. General subdrainage require <br /> ments are not anticipated. <br /> 5: Weak/Compressible Soils -- Weak and/or compressible soils are <br /> :expected to be limited in extent and mitigable through over-excava- , <br /> on and replacement as engineered fill and appropriate structure <br /> r <br /> esign. <br /> ~y: Expansive Soils -- Expansive soils conditions are expected <br /> Obe' limited in extent. where identified they can be readily <br /> ligated through appropriate design and construction. Expansive <br /> 1s conditions .are substantially mitigated in the presence of <br /> allow groundwater . <br />
