Quantico Marine Corps Base has released a study of what 3,000 more jobs will do to base and local roads, the environment and the region's socioeconomic picture.

The 308-page draft environmental impact statement is not a quick read. The military has been working on the report for more than a year.

Among the major findings and key facts:

The new jobs will be based west of Interstate 95. Several locations are being considered. One is near Russell Road, and the others are in a region referred to as MCB-1. All sites will require new construction.

If something is built, Russell Road must be widened from U.S. 1 west to the job sites, and traffic signals are recommended at up to nine intersections on Russell Road.

Secondary road intersections on the base operate at "acceptable" levels, but base access points operate at "unacceptable" levels during peak commuter periods.

In North Stafford, additional turn lanes and signal changes are recommended at the intersection of Onville Road and State Route 610.

If family sizes follow the national average, incoming workers would add 4,300 to 7,000 adults to the area and 850 to 1,400 children. The higher numbers are possible if Quantico adds another 2,000 jobs to the 3,000 shifted there by the federal Base Realignment and Closure Commission.

BRAC expects 263 students at Quantico, who will need lodging.

None of the potential sites negatively impacts land. Impact on migratory birds and waterfowl would be "minimal."

The jobs were proposed at Quantico by BRAC in 2005.

BRAC also called for Fort Belvoir in Northern Virginia to get 22,000 additional jobs. But last week there were reports that about 10,000 of those jobs are moving to a new location near Springfield Mall. The site is within walking distance of Metro and Virginia Railway Express stations.

Both military installations are assembling environmental impact statements, a federal re- quirement. Public comment is part of the process, and Quantico is accepting input through Sept. 4. Two meetings have been scheduled to include the public in the process.

Transportation recommendations in the draft EIS were presented to the Commonwealth Transportation Board last week.

Cord Sterling, a board member from Stafford, said the jobs are a positive development for the community on the whole, but he's worried about a few transportation hot spots.
