Proposals for Revising Northern California Metroplex – Alameda County/Contra Costa County 34 TRUKN TWO—NOISE FORUM REQUESTS: The Forum requests the FAA consider TRUKN proposals in two sections as detailed above – TRUKN North and TRUKN East. The Forum also requests the FAA consider the WNDSR proposals above as part of overall noise mitigation for TRUKN. As detailed above, moving WNDSR TWO has additional significant advantage in that it frees airspace so that SFO and OAK departures can eventually use quieter and more fuel efficient continuous climb procedures. TRUKN TWO NORTH REQUEST: The Forum requests that the FAA restore the historical traffic concentrations in the topographically lower areas where it existed prior to NextGen and that communities grew and developed under. To accomplish this, the Forum requests the FAA move the current GRTFL and DEDHD tracks westward of Highway 13 and East Oakland to reestablish and better restore historical patterns of SFO departing traffic in this area as the proposed mitigation (Figure 20). The Forum also requests the FAA adjust the TRUKN waypoint to better restore the legacy earlier turn northward over the Bay and keep the lower altitude portions of the climb occurring over water instead of communities in Alameda, East Oakland and San Leandro. Figure 20: Preferred mitigation proposal to restore traffic patterns to TRUKN North. Figure shows traffic restored by sample adjustment of tracks westward to echo where traffic was prior to NextGen and under which communities developed and grew. Sample Pre NextGen 2014 flight paths shown to exemplify restoration of previous traffic pattern. Prior to NextGen, aircraft turned northward further west over the Bay which kept traffic over the water during the lowest part of the climb. TRUKN shifted traffic from the water to communities in Alameda, East Oakland and San Leandro. 226
