Fairfax County supervisors swallowed a long list of individual grievances Monday to unanimously pass a $3.3 billion budget that leaves few completely happy but balances county spending by closing a $650 million shortfall.

It is the first spending plan approved since Democratic Chairwoman Sharon Bulova took the reins of the 10-member board. The budget’s loudest detractors came not from the board’s Republican minority, but from Democrats unhappy with what they believed to be a retreat from the county’s commitment to affordable housing.
