According to the comptroller’s web site, five audits have been released so far in 2012, including the blockbuster audit of city water billing practices that has resulted in the city’s promise to refund more than $4 million in overbillings to consumers. There were 10 audits published in 2011, 15 in 2010, and 19 in 2009. In those years, the War Memorial Commission was audited three times, as required by state statute. There were no comprehensive audits of the Police Department, the Department of Public Works, or the Department of Housing and Community Development. Those three city agencies have a combined annual budget of about $900 million—about 30 percent of total city expenditures.
