Vage 2 December 18, 2003 Mr. Brady next identified aircraft noise and airspace safety as the potential AELUP issues. Referring to graphic depictions, he described the JWA noise footprint easterly of the project and the actual radar traclts of arrivals to Runway 19R for the 24 -hour period of November 1, 2003. Ile noted that JWA operations data show about 102,000 annual arrivals to 19R primarily by jet/turboprop aircraft, adding that staff has updated the AVA Airspace Map with the project site and the adjacent high -rise office building. Mr. Brady next cited the cautionary statement about aircraft noise in the FAA's Determination of So Hazard for the project, anal he explained that the 13 -story residential tower will rise from a 3 level parking structure, thus accounting for the unprecedented physical height at that location, Re opined that the combination of height and residential use serves to make this project unique and some portion of future residents will be annoyed by aircraft noise. Mr. Brady next reviewed in detail the FAA's Determination, and his follow -up discussions with FAA staff, He explained the FAA requirement for subsequent filing by the sponsor, with the FAA to use the Finished project data for future airspace analyses and chart publishing, Mr. Brady described the FAA's circular search, within a 2 -mile radius, that identified 358 prior aeronautical studies With a two page listing of structures at least 250' in height, He noted the FAA finding that the project will penetrate the JWA Horizontal Surface by 31', but will not impact any current or planned aircraft procedures. He stated that staff does not Iaiow whether the ntuiterous structures compiled by FAA are in the approach area or are off to the sides of JWA, and he pointed out the AELUTs recognition of the FAA's expertise and authority on airspace and the requirement for rooftop obstruction lighting as mitigation by both the FAA and the AELn Mr. Brady concluded that the project is technically consistent with the AELUP while being less than a desirable use so close to the 1WA approach, and he recommended a Finding of Consistency for the project with conditions requiring flail FAA compliance and Notice of Airport in Vicinity to all future occupants perAELUA Section 3.3.6. added a brief description ob of his conversations with FAA staff, his results from searching the FAA's obstruction evaluation Website database, and lie noted the presence of the project sponsors and the City's planner who could address questions. Replying to Commissioner H. Beverburg, Mr. Brady explained that "technically consistent" is meant to convey the situation where the Project's physically extremely high and close to JWA and is a residential use, Surface the project is not within the JWA noise footprint and although it penetrates the Horizontal Surface, so do many other buildings to the cast and west of the airport Again replying to the Commissioner, Mr, Brady explained his having learned that "critical to flight Safety" means that FAA insists on subsequent filing of the building's final, as -built height azid location data, which will be added to their airspace database for inclusion in future aeronautical studies and possible depiction on future aeronautical charts, He added that staff does not aeronautical how much closer the project could get without becoming a hazard to air navigation Commissioner H, Beverburg observed that FAA rarely issues Hazard Determinations, but rather will gather such information until a dangerous point is reached when the thresholds must be moved and the minimunis raised.
