However,not all obstructions are necessarily hazards. The determination of whether an object would be a hazard to air navigation is made as part of an aeronautical study conducted by the FAA. Subpart B,Notice of Construction or Alteration, of the FAR Part 77 regulations requires that the FAA be notified of any proposed construction or alteration of objects within 20,000 feet of a runway and having a height that would exceed a 100:1 imaginary surface (1 foot upward per 100 feet horizontally)beginning at the nearest point of the runway. This requirement applies to runways more than 3,200 feet in length. For shorter runways, like Runway 12-30 at San Carlos Airport,the notification surface has a 50:1 slope and extends 10,000 feet from the runway. Notification is required with regard to any public-use or military airport. Also requiring notification is any proposed structure or object more than 200 feet in height regardless of proximity to an airport. The airspace protection surfaces for San Carlos Airport and the FAA notification surface are depicted on Exhibitn3-4. AirspacelProtectiomCompatibilityvCriterimanchPolicies4onSamCarlosv Airportv The following are draft airspace protection compatibility criteria and policies that may be included in the ALUCP for San Carlos Airport. Airspace Protection Policy 1 -Airspace Protection Compatibility for New Development Tall structures,trees, other objects, or high terrain on or near airports,may constitute hazards to aircraft in flight. Federal regulations establish the criteria for evaluating potential obstructions. These regulations require that the FAA be notified of proposals related to the construction of potentially hazardous structures. The FAA conducts"aeronautical studies"of proposed projects to determine whether they would pose risks to aircraft,but it does not have the authority to prevent their creation. The purpose of the ALUCP airspace protection policies,together with regulations established by local land use jurisdictions and the state government, is to avoid the creation of hazards to navigable airspace. The airspace protection compatibility of proposed land uses within the Airport Influence Area for San Carlos Airport shall be evaluated in accordance with the policies in this section and the airspace protection surfaces depicted on Exhibit 3-4. The policies set forth in this section apply to the entire Airport Influence Area for San Carlos Airport(i.e.,Areas A and B).
