Structural fill to bc placed for sitc grading should bc co�istructed over proof-rolled, unyiclding, undisturbed, firm, native bcaring soils lollowing the siripping of surficial unsuitable soils. GGOLOGIC IIAZARDS AIVD REMEDIATION Landslidc liaz:vd The very-dense Gcsh till soils underlying the site at shallow depth arc of high shcar strcngth nnd have good resistance against slopc failures. Therefore, the potcntial for deep-seatcd landslides to occur on the sitc should bc minimail. Erosiun H:uard The loose fill, topsoil and �vr.ithcred soils are of low lo moderatc resistanc� aguinst crosion, while the undcrlying very-dense till soils are oC moderately hibh resistance against erosion. �rosion may occur over the st�eper portions of the site if die we�ilcer surficial soils are devoid of vegetation cover and overly saturated. To mitigate crosion hazard. vegetation cover outside o1� construction limits should be maintained and any unpaved exposed ground within the site resulted from construction activities should be rc-vcgetatcd as soon as possible. Concentrated stomiwater should not be dischazged onto the ground within or adjacent to the site. Stormwater over impervious surfaces, such as roofs and paved drivew�y, shouid be captured by underground drain line systems wnnecled to roof downspouts and by catch basins installcd in the paved driveway. Watcr collected by these drain line systems should be tightlined to discharge into a storm sewcr. LIU & ASSOCIAT�S, IN�'.
