The Fairfax County Board of Supervisors yesterday delayed action on a six-year, $129.2 million state road improvement program after supervisors and residents complained that it does not address problems quickly enough and that there has been too little public input.

Also, some supervisors criticized a Metro report that they said underestimates the amount of parking that is needed near Metrorail stations in the county, adding that additional parking spaces should be provided on an "expedited" basis.

The actions appeared to indicate that the supervisors, most of whom were elected in November on campaign promises to improve the county's transportation network, are becoming frustrated with the slow pace of progress and the high cost of improvements. County Board Chairman Audrey Moore said state and county officials were "not hearing" her message that transportation improvements have to be completed more quickly.

After being told by the county staff and state officials that some of the 57 projects on a state list of secondary road projects would take two to three years to design, Moore lost her temper, saying that this was unacceptable. She said that it should take no more than two years from the time a road is financed to the start of construction.

"The message from the public and the board is that we've got to accelerate things and we're going to need more funding and we're going to have to go to the public for it," Moore said.

She said the state, which is responsible for road construction and maintenance in the county, must provide more money for roads. She added, "This county is going to do everything we can under the sun to bring that about."

About a dozen speakers testified at a public hearing on the Virginia Department of Transportation's proposed six-year secondary road improvement program, and most criticized what they said was a process that discourages citizen input in selecting projects.

The state program finances road design, land acquisition and construction. According to a staff report, the most money -- $22.7 million -- would be allocated for fiscal 1989, which begins July 1, and it would decrease every year to $19.9 million in fiscal 1994.

E.M. Risse, a member of the Fairfax County Chamber of Commerce board of directors, said that the "process for public notification and participation in the priority selection process is inadequate." He said that the priority list for Fairfax appeared to be unrelated to regional transportation planning.

The board delayed approving the program until March 14, allowing county residents more time to submit comments on it.

Also, the board reviewed a report by the Metro board that estimates that 10,000 new parking spaces are needed near Metrorail stations in the region, including about 2,130 near the Vienna, Dunn Loring, West Falls Church and Huntington stations in Fairfax County.

Supervisor Joseph Alexander (D-Lee), chairman of the Metro board, said that as many as 1,000 spaces might be needed at the Huntington station alone.

In other action yesterday, the Fairfax board:

Approved a new procedure for scheduling public hearings on land use rezonings and special exceptions before the Planning Commission and the county board, the two bodies that must approve land use applications. Under the new system, the board will not schedule a public hearing until after the Planning Commission has made a decision on a case. The change will leave three to four weeks between Planning Commission decisions and board hearings, compared with only four days in some instances under the old system.

Ordered the county staff to contact Domino's Pizza to state the board's "concerns" about the company's policy of giving $3 off for any delivery that takes longer than 30 minutes. Supervisor Sharon Bulova (D-Annandale) said the deadlines are dangerous because they may encourage reckless driving by Domino's employees.
