This is accomplished by the establishment <br /> of compatibility policies that seek to prevent the creation of land use features that can be hazards <br /> to the airspace used by aircraft in flight and have the potential to cause an aircraft accident to <br /> occur. Such hazards may be physical,visual, or electronic. <br /> 3.3.3.21Evaluationv <br /> Tall structures,trees, other objects, or high terrain on or near airports,may constitute hazards to <br /> aircraft. Federal regulations establish the criteria for evaluating potential obstructions. These <br /> regulations require that the FAA be notified of proposals related to the construction of potentially <br /> hazardous structures (see Appendix C from the ALUCP). The FAA conducts "aeronautical <br /> studies"of proposed projects to determine whether they would pose risks to aircraft,but it does <br /> not have the authority to prevent their creation. The purpose of ALUC airspace protection <br /> policies,together with regulations established by local land use jurisdictions and the state <br /> government, is to avoid the creation of hazards to the navigable airspace. The policies set forth in <br /> this section apply to the entire AIA. <br /> 3.3.3.3â– Measurementy <br /> Federal Aviation Regulations (FAR)Part 77, Objects Affecting Navigable Airspace,provides <br /> guidance for the height of objects that may affect normal aviation operations. The guidance <br /> provided by Part 77 is not absolute,however. Deviation from the Part 77 standards does not <br /> necessarily mean that a proposed object is prohibited from construction, only that the offending <br /> object must be evaluated by the FAA and that mitigation, such as marking or lighting may be <br /> required. Figure 3-5 (from the ALUCP) depicts the Part 77 surfaces in the vicinity of HWD. <br /> 3.3.3.41FactorsEDetermining v4irspacelProtectionZriteriav <br /> As described above, airspace protection policies rely upon regulation enacted by FAA and the <br /> state of California;ALUC policies are intended to help implement the federal and state <br /> regulations. <br /> a f FAA has well-defined standards by which potential hazards to flight, especially airspace <br /> obstructions, can be assessed. However,FAA has no authority to prevent the creation of <br /> such hazards;that authority rests with state and local officials. <br /> bf California airspace protection standards mostly mirror those of the FAA;the primary <br /> difference being that state law gives the California Department of Transportation,Division <br /> of Aeronautics and local agencies the authority to enforce the standards. <br /> SanfCarlosfAirportV C-17 ESAfAirportsf/130753f <br /> ALUCPf W hitef Pape/ Junef2014f <br />
