HERCULES -- Three months after Nelson Oliva and his family company settled a $3.2 million lawsuit with the city, the City Council is poised to ask the District Attorney to investigate potential criminal wrongdoing by the former city manager.

Oliva oversaw development for the city from April 2007 to January 2011 and steered city contracts to his family company. Under his tenure, the city spent millions in redevelopment funds for projects that were never completed.

"The citizens of Hercules are entitled to an explanation why no criminal charges have been filed against anyone," said Councilman Bill Kelly, who along with his four colleagues ran on promises to clean up City Hall and wants Contra Costa District Attorney Mark Peterson to investigate. "The citizens of Hercules deserve nothing less."

The council action comes three years after a housecleaning at Hercules City Hall that included a complete makeover of the council and some top management. There is an ongoing investigation by federal law enforcement, but no one has been charged with a crime.

Oliva was fined $70,000 in November by the state Fair Political Practices Commission for conflicts of interest and unreported gifts. Days earlier, Oliva and his family company, NEO Consulting Inc. (DBA Affordable Housing Solutions Group,) agreed to settle a lawsuit with the city for $3.2 million, the amount he directed toward family contracts for housing, loan and construction management and administrative services.

Oliva and his attorney, Richard Ewaniszyk, could not be reached for comment.

The council will meet on the matter at 7 p.m. Tuesday at Hercules City Hall, 111 Civic Drive.
