A motion to restudy the McLean central business distirct made Monday at the Opening session of the Fairfax County Supervisors' annual review of the county's comprehensive plan fell on deaf ears and died of lack of a second.

Supervisor John P. Shacochis (R-Dranesville) got only a feeble attempt at support from Supervisor Martha V. Pennino (D-Centreville) who proposed a public hearing in June to discuss whether the citizens wanted another study of the zoning and land use patterns already established in the McLean central business district. Her proposal failed by a 4 to 4 vote, with Supervisor Joseph Alexander (D-Lee) absent.

As the public hearing on amendments to the county's, comprehensive land use plan in areas I and II progressed, the Supervisors supported, across the board, recommendations of the McLean Citizen Association.

"This is a victory for responsible citizen participation and for their capacity to plan their future," said Lilla Richards, first vice president of the McLean Citizens Associations.

"The Board of Supervisors is supporting not only the PLUS plan (the county's comprehensive land use plan) but the procedure to amend it as well."

Eight of the nine proposed amendments to the plan which had been endorsed by the citizens association were accepted by the Supervisors. The ninth amendments was deferred.

The loudest sigh of relief from the McLean residents came after the Supervisors agreed with the county's planning commission to keep a parcel of land at the intersection of Rtes. 123 and 193 zoned for 2 to 3 units per acre and to deny a request to rezone it for 4 to 5 units, which could have permitted townhouse development there.

The property in question is situated across from the CLA and next to "Hickory Hill," the home of Ethel Kennedy.

Earlier in the day at their regular meeting, the Supervisors unanimously supported a move by Board Chairman John F. Herrity to request that the ongoing alternative analysis study by Metro include the alternative of an all-bus system.

The all-bus system is what Fairfax County residents now utilize and Herrity wants this option included in the overall study of alternate suburban routes of Metro.

Under an all-bus system, the only place at which commuters would transfer to trains on their ride into Washington would be at the Huntington station, scheduled to be built in Fairfax County.

Fairfax County was allowed to select six alternatives to be evaluated under the alternative analysis study. This last alternative, which Herrity readily admits was possible only after the federal government's approval of construction of Rte. I-66, is a seventh alternative.

In other action, Supervisor Alan R. Magazine (D-Mason) got approval of a resolution asking the Virginia Department of Highways and Transportation to analyze, again, traffic patterns in the Annandale central business district in order to re-open the right-hand turn from Backlick Road onto Columbia Pike.

The Fairfax Supervisors have also requested that the Federal Aviation Administration and the Metropolitan Council of Governments come to Fairfax next Tuesday to explain the proposed landing and take-off routes at National Airport.

All the incoming and outgoing planes at National now use one major route over the Potomac River and FAA recently proposed that several alternative routes be used in order to reduce the amount of noise in the Potomac corridor by dispersing it over a larger area. The Fairfax Supervisors, who have been fighting the landing of Concorde at Dulles because of noise, are now worried that southern Fairfax citizens will be annoyed by more airplane traffic noise from National if the new routes are implemented.
