BROOKLYN - City Comptroller John C. Liu has released an audit of the Parks Department's work, exposing long wait times to fix hazards in some of the city's playgrounds.

From April 2011 to March 2012, the Parks Department was able to fix most of the problems reported within 30 days. However, the audit found that hundreds of hazardous conditions on playgrounds went untouched for months.

The comptroller's office says that out of 583 hazardous conditions in Brooklyn parks requiring immediate attention from 2011-12, 8 percent were not addressed within a 30-day period, including some that took more than a year to resolve.

The Parks Department released a statement in response to the comptroller's request for faster fixes, and said it would continue to make safety its top priority. It also disagreed that issues were not addressed in a timely manner.
