Fairfax County needs to increase transportation spending by $100 million to $150 million during the next several years, with most of the funds generated through tax increases, according to a long-awaited report on the county's future.

The recommendation comes in a 90-page report by the Fairfax County Goals Advisory Commission, established last February by the county supervisors after a controversial debate over limiting development. Some officials complained at the time that the issue was being delayed until after the supervisors' November election.

The report, a draft of which was released yesterday, suggests that the county's transportation crisis has become so bad that residents and businesses would not fight a tax increase to finance road improvements if spending in other areas, such as the county and school system operating budgets, remained constant.

The study also calls for completely overhauling the county's Comprehensive Land Use Plan by 1990, and integrating it with a new countywide transportation plan and a revised Capital Improvement Program for public facilities.

Although transportation and land use were the most publicized aspects of the commission's work, the report also analyzes the county's progress in such areas as education, affordable housing, human services, and culture and recreation. "All {areas} must be dealt with quickly, thoughtfully and forcefully if we are to continue to prosper," the report said.

Composed of some of the county's most influential business and civic leaders -- including developer John T. (Til) Hazel and former Board of Supervisors chairman Jean Packard -- the 22-member commission was created in response to the County Board's controversial December 1986 decision not to reduce the amount of development allowable on 10,000 acres of land zoned for industrial use.

Many officials believe that the divisive development issues that boiled to the surface during the so-called I-Zone debate catapulted three new "slow-growth" supervisors into office and led to Democrat Audrey Moore's landslide victory over Board Chairman John F. Herrity in the November election.

The goals commission met dozens of times, held public hearings and received briefings from the county staff and other experts about 16 broad goals drawn up by a similar committee in 1975. The commission evaluated the county's progress in those 16 areas and in its report makes 285 recommendations for changes in county policies and procedures.

Commission and government officials said the draft of the final report, which was approved unanimously by the commission, is being proofread and that no major changes are expected before the final version is presented to the Board of Supervisors Jan. 11.

Highlights of the report include:

Transportation. The report recommends "a major revision" of the county's transportation plan "based on achieving . . . specific levels of service throughout the county by balancing transportation and development."

The "highest priority" should be obtaining additional financial support from the state, the report says. At the same time, the report criticizes the Virginia Department of Transportation, noting that it "has failed to provide either effective planning or local design and construction of roads" and "has not demonstrated any innovations for funding, implementing, or expediting transportation improvements."

During the estimated two to three years that it would take to devise a new comprehensive land-use and transportation plan, the report suggests, the county should spend $50 million annually in new road construction "as a good-faith effort to encourage the {state} to assume its primary responsibility for highway construction funding."

The report says the funds should come not from bonds -- the way the county usually finances roads -- but from higher real estate, personal property, sales or capital gains transfer taxes.

Land use. In revising the county's comprehensive land-use plan, county officials "should develop timing mechanisms to manage the pace of development," getting enabling legislation if necessary, the report says. The revised plan also should "establish the amount, type and location of open space to be preserved," and "establish a policy for redevelopment of existing commercial and residential developments of all sizes."

The report suggests the county set aside low-cost industrial areas to encourage more service industries and minority-owned and small businesses. The study recommends a "comprehensive review" of the county zoning ordinance and the density of development allowed in all zoning districts.

Human services. The commission found that human services such as public and mental health services, programs for the elderly, preschool education, housing and job opportunity services "suffer from an inadequate level of funding."

The report recommends that the county appoint a human services council by March and develop a comprehensive human services plan by August. Child care services, especially for low- and medium-income families, must be increased, the report says, and it calls on the county to recruit family day care providers at a rate of 400 to 500 annually during the next five years.

The report recommends that the county give "immediate attention to certain critical health care demands, including early teen-age pregnancies and day health care centers for the elderly, for Alzheimer's victims and for AIDS victims."

The county should develop a six-year plan to address "critical" needs such as increased emergency housing and shelters, more residential care facilities for the mentally handicapped and emotionally disabled, and more services for the chronically ill, the report says.

Affordable housing. The study notes that a lack of affordable housing makes it difficult to attract and retain county employes and limits the labor pool for service and entry-level employes in the private sector. It also notes that many people who work in the county live in other jurisdictions and commute to work, contributing to traffic jams. The report recommends that the county seek more affordable-housing proffers from developers when their site applications are approved. The report also says the county should be prepared to purchase about 2,500 low-cost housing units that are controlled by the federal government and that probably will come up for redevelopment by 1990.
