Problems described in the April 22 front-page article “Big firms scooping up home bargains,” about Wall Street firms outbidding individuals for homes in recovering real estate markets (such as this one), and in the same day’s Metro article “Budget cuts threaten to upend Fairfax man’s fragile existence” are aggravated by the failure of most area jurisdictions to plan for, and permit, enough housing for their ­workforces.

That failure also worsens the effects of gentrification in Alexandria, the closing of the District’s public housing list, homelessness and declining affordability in and around the city. The resulting inadequate housing supply hits low- and moderate-income people hardest.

Major potential sources of new housing in Northern Virginia are being planned along the new Silver Line to Dulles Airport and eastern Loudoun County. But the local governments that ultimately will make the decisions about these communities have resisted allowing enough housing for future workers in those areas.

There are many documented success stories of communities near transit that are predominantly residential. New residents generally are not a significant drain on local government finances, as some officials fear.
