Cities are getting big revenue boosts from U.S. states, leading some municipal budgets to recover from the 2007-09 recession, Pew Charitable Trusts found in an analysis of financial reports for the 30 most-populated cities released on Monday.

A time lag in assessing property taxes, the largest revenue source for cities, caused the recession to hit local budgets later than state and federal ones and prolonged the economic pain. Through 2011 cities continued to cut services, tap reserves, shrink pension contributions and raise taxes, Pew found.

Still by fiscal 2011, which for most cities ended on June 30, 2012, the revenues of nine cities reached their pre-recession peaks. Two were in Texas: San Antonio and Dallas. Revenues for Washington, D.C., Atlanta, San Francisco, Pittsburgh, St. Louis and Chicago also had recovered.

Portland, Oregon had the highest level, with revenues near 110 percent of the pre-recession peak, Pew found.

"In each, aid from other governments was the first- or second-largest contributor of growth as city revenue recovered," Pew found. "This group of cities typically got larger increases in intergovernmental aid and received infusions from states and the federal government later...than did the other 21 cities."

Revenues were approaching pre-recession levels in five other cities by 2011, the last fiscal year full data was available: Baltimore, Cincinnati, Denver, New York, Philadelphia.
