instructions, which would ensure that the plane avoided Project buildings, or would follow published instructions, which would normally require the plane to continue straight ahead, parallel to the runway. Under such conditions, the airplane would not come close to the 10-story building. 3.10.12 Potential Effect: The safety of the individuals inhabiting the buildings, especially the ten-story office building, could be affected by aircraft overflight. The density of occupancy could result in safety concerns. Findings: The GID hereby makes finding (1). Facts in Support of Findings: (a) The Airport Study carefully reviews FAA airport safety guidelines. The Airport Study concludes that the Project will not conflict with the FAA Object Free Area or Runway Safety Area. (b) The Airport Study also concludes that the Project will not conflict with the Runway Protection Zones ("RPZ"), whether existing or potential (as depicted on the current Airport Land Use Plan and approved by the FAA and Caltrans Aeronautics Program). The RPZ is intended to enhance the protection of people and property on the ground from aircraft either landing short of the runway or overrunning the runway end on take-off. (c) In 1983, Redwood Shores, Inc. voluntarily reduced heights of buildings within two flight corridors at San Carlos Airport to 50 feet above ground level (60 feet MSL). The flight corridors are incorporated into the City's General Plan. The Project does not conflict with the flight corridors. (d) Approximately 8.3 acres, or 18.4 per cent of the Project site, is located within the Inner Turning Zone (safety zone 3). Within this area, the 4-story, 140,000 square foot office building would cover approximately.83 acre of ground area. The remaining portion of the Project site within safety zone 3 would be devoted to parking and landscaping. The probability of any one-acre site located in safety zone 3 being the site of an accident is .11 per cent, or 1 in 909. In other words, out of 909 aircraft accidents, only one would have the potential of affecting any one specific one-acre location within safety zone 3, including the office building to be located in the Project site. This is not a statistically significant probability, in light of the accident rate of 1-3 accidents per year, on average. (e) The Traffic Pattern Zone (safety zone 6) incorporates the remaining 36.7 acres (81.6%) of the Project site, including the 7, 8 and 10-story office buildings. -29- GIDEIRFD.DOC 7/23/96 5:44 PM
