(h) Because safety area land use density restrictions are more effective when applied at a general plan or large development level, measurement on a gross acre basis is most appropriate. On this basis, the 4,000 people expected to occupy the 45-acre site under maximum occupancy conditions results in an average density figure of 89 people per gross acre. This is well within the density criteria established in the Handbook. (i) No portion of the Project is located in the San Carlos Airport approach zone shown in the CLUP. (j) The Airport Study evaluates risk factors associated with air transportation injuries, and supports the conclusion that the risk is low. In statistical terms, an individual is over 100 times more likely to die from an unintemional injury, or almost 60 times more likely to die from injuries sustained in an automobile accident, than in an aviation-related accident. Involvement in a fatal general aviation accident is even less likely. 3.10.13 ~: Airspace protection could be adversely affected if buildings on the Project site exceed 100 feet. The heights of the 7, 8 and 10 story office buildings could seriously affect the operation of aircraft using the airport. F. AIIlIilI~: The City hereby makes finding (1). Facts in Support of Findings: (a) No portion of the Project, including the 10-story office building, would penetrate the FAR Part 77 imaginary surfaces for San Carlos Airport. As such, no Project component should represent either an obstruction or a hazard to air navigation as defined by Part 77 of the Federal Aviation Regulations, because such criteria "are more restrictive than is needed for safe flight operations." (b) The FAA is responsible for administering Part 77 of the Federal Aviation Regulations (FAR Part 77). The FAA's objective is to "ensure the safety of aircraft and the efficient use of navigable airspace by the almraft." (FAA, Advisory Cimular 70/7460-21, "Proposed Construction or Alteration of Objects that May Affect the Navigable Airspace," p. 2.) Pursuant to Subpart B of FAR Part 77, the Project was required to submit FAA Form 7460-1, "Notice of Proposed Construction or Alteration," to the manager of the regional FAA Air Traffic Division. The FAA then conducted an aeronautical study of the Project's potential effects, including the "extent of [any] adverse physical or electromagnetic interference effect upon the navigable airspace or air navigation facilities." (FAA Order 7400.2C, "Procedures for Handling Airspace Matters.") (c) On June 17, 1996, prior to the last two Planning Commission heatings on the Project, the FAA issued its determination. The FAA stated as follows: "The -30- 7/11/96 9:56 AM
