The Project proposes to expand the existing Kaiser Permanente Los Angeles Medical Center (Medical Center) campus by replacing facilities and adding new buildings, developed in three consecutive phases. Phase 1 of the Project would include demolition of existing commercial and residential structures and surface parking lots on Sites 1 and 2, and two medical office buildings (MOBs) on Sites 3 and 4, and construction of a parking structure and MOB on Site 1 and a procedure center addition to the existing MOB on Site 2. Phase 2 would include the demolition of an existing parking structure and MOB space on Site 5 and construction of a new, larger parking structure with ground floor commercial retail space, and construction on Site 4 of either a MOB (Option A) or a hospital addition (Option B). Phase 3 of the Project would include construction of a new MOB on Site 3 and a parking structure on the south side of the existing parking structure on Site 6. If Option A is selected for Phase 2, the MOB constructed at Site 3 would be smaller (41,500 square feet). If Option B is selected for Phase 2, the MOB at Site 3 would be larger (73,500 square feet). Proposed buildings for all three phases would total 401,100 square feet of floor area under Option A or 433,100 square feet of floor area under Option B, with an additional 533,400 square feet of parking structure area.
