Exhibit A Geotechnical Requirements for Development on Portions of Developed Lots Formerly within the Geotechnical Setback Area, or "Berlogar Line" 1) Any structures and improvements constructed on the slope of the ancient landslide mass shall have flexible utility connections to accommodate ground movement during an earthquake. 2) During a major earthquake, deformation of the materials in the ancient landslide may occur. To accommodate this potential deformation, the foundations for all structures within the geotachnical setback area shown on the attached plan, Exhibit C, shall be designed and reinforced to withstand the anticipated deformation. 3) Any necessary remedial work for both active, older active, and recent landslides shall be similar, because the older active landslides have nearly the same potential for future movements as the active landslides, and because many of the so-called recent landslides may also have significant potential for future activity. The necessity for remedial work shall be determined by the City Engineer or peer review consultant. 4) The currently proposed buttress for the lot encompassing the three existing structures (two caretaker units and one barn) may not be of sufficient size to restrain the very large landslide complex which extends upslope and beyond the limits of the project site. It does not appear that the proposed buttressing shown on Map 5-1 of the draft SEIR (dated March 1998) would provide adequate mitigation for future development or structures. Additional site-specific design work shall be performed to the satisfaction of the City to address this issue prior to any future development or structu~s on this lot. 5) All water collected within the building pads (including roofs of structures and paved surfaces) shall be transported to an approved storm drain system. No collected water shall be allowed to discharge onto project slopes. 6) All geotechnical-related improvements completed as part of new development in this area shall be included within the scope of the Geologic Hazards Abatement District, including monitoring, maintenance, liability, etc., developed for Phases 1 and 2 of the Oak Tree Farm subdivision. 7) For any proposed improvements, including residences, accessory structures, pools, etc., proposed to be constructed within this geotechnical setback area, a geotechnical analysis may be required to be submitted by the property owner at the discretion of the Planning Director and City Engineer. The property owner shall be responsible for hiring a geologist to perform the necessary geotechnical analysis and submitting it for the review and approval of the Planning Director and City Engineer. If the City determines that the analysis needs to be reviewed by a peer reviewer, the property owner shall be responsible for reimbursing the City for the cost of all peer review services it deems necessary. The property owner shall be responsible for incorporating all recommended mitigations and requirements resulting from the City's review into the proposed design and ensuring that these are completed.
