Conventiunul footing fo�mdations poured on or into the Gesh Esperancc Sand soils may bc uscd for sup�rting ►hc buildings. Duc to the sensitive nature of the steep slo�: within thc subject lot, grnding and foundation construction work for the proposed residences should proceed and be completed during thc dryer months 1'rom April 1 to Gctober 31. The site should be stabiliud with proper erosion control in place beyond this dry season grading period. If conswction work to be carried out outside of the above drycr period, the rccommendations for sile stabiliwtion, erosion mitigation and drainage control in this rcport should be in place and operetional on a daily basis, end the site stability should be monitored by a geotechnical engincer daily during site gtading. GEOLOGIC HAZARDS Landslidc Hazards The hillside on which the subject lot is siwated is formed with dense to very-dense, Gesh, L'•sperancc Sand soils nt shallow depth. These soils are of moderately-high tu high shear strength und have high resistancc aguinst slope failures. 'I'hcn�fore, the risk for decp-seated landslides culting into the ticsh Espersncc Sand de�sits underling the subjcct lot should be minimnl. F.rosion Hazard l�he surficial topsoil and loose wcathered Gsperance Sand soils mantling the stecper portion of the subject lot can bc easily eroded if devoid of vegetation and overly saturatcd. Pmgrcssive erosion can result in shallow mudtlow•s in the we�ilcer surficiul soils. To mitigate such erosion potcnti:d, the vegctation cover outsiJe of construction limits should not tx: disturbed. Concentrated stormwater shoulJ not lx released onto the ground within the lot or adjacent proExrtics. Unpaved ex�wsed groand within thc lot resulted Gom construction uctivities should bc rc-vcgetated a soon as possible. Stortn runoff ovcr im�rvious surfaces, such ns roofs and Jrivcways, should be captured with undergrounJ drain line systems connected to roof LIU & ASSOCIATES, INC.
