Proposals for Revising Northern California Metroplex – Alameda County/Contra Costa County 19 REQUESTED INITIAL FAA RESEARCH FOR OAK ARRIVAL ALTERNATIVE ONE: The Forum requests the FAA research and identify appropriate adjustments to avoid population and better achieve a quiet descent procedure into OAK. NEW OAK ARRIVAL PROPOSAL ALTERNATIVE TWO: The Forum requests the FAA consider establishing an OAK arrival RNAV routing of traffic to the Mendocino VOR direct to the Santa Rosa VOR towards the Concord VOR crossing Concord VOR at 10,000 feet and then routing down the California Interstate 680 highway corridor to the Oakland Runway 30 final approach (approximating the CCR 155 or 150 degree radial) (Figure 11). Establish routing to stay on the California Interstate 680 highway corridor at high altitude to enable a fuel efficient, quiet, reduced power descent approach to OAK. An alternative modification could use the initial WNDSR TWO arrival or Mendocino VOR to Santa Rosa VOR (or abeam it) toward Concord VOR at 10,000 feet. This routing allows aircraft to be kept high for fuel conservation, a quiet, reduced power descent, and Class B airspace protection from VFR aircraft starting at the CCR VOR. This routing and higher altitude follows the industrial areas and California Interstate 680 highway corridor and makes good use of compatible overflight land for noise abatement instead of placing flights over densely populated residential areas in topographically higher areas. It increases safety for SFO and OAK departures, due to reduced potential conflict with OAK arrivals. Another advantage is that it frees airspace so that SFO and OAK departures can eventually adopt quieter and more fuel efficient continuous climbing procedures. 211
