Smithtown Highway Superintendent Glenn Jorgensen pleaded not guilty Wednesday to felony charges accusing him of tampering with public records for a town paving project, Suffolk County District Attorney Thomas Spota said.

Jorgensen, 63, of St. James, was directed to appear in First District Court in Central Islip for his arraignment, where he faced several charges, including tampering with public records, falsifying business records, filing false records, official misconduct and grand larceny, relating to incidents dating back to Nov. 18, 2014.

The district attorney alleged that Jorgensen directed a highway foreman to alter road construction reports to conceal that he had approved a contractor, Suffolk Asphalt Corporation of Selden, to pave at least eight Smithtown streets in freezing temperatures in November. The altered records misrepresented the weather conditions during the repaving work, Spota said.

Jorgensen’s misdemeanor grand larceny charge also accused him of stealing a public work order for the improper repaving and taking the official document home. District attorney detectives found the records in Jorgensen’s Hope Place residence, under his bed, Spota said.

“State department of transportation construction standards dictate asphalt must not be applied to a road surface in freezing temperatures and, in fact, the town’s own engineer has said repaving in freezing weather would result in the asphalt falling apart,” Spota said. “The repaving of a residential street doesn’t happen that often and when it does, residents are paying for a job done correctly, not a faulty repaving that will soon need pothole repair work.”

Both Jorgensen and Anthony M. La Pinta, a Hauppauge-based attorney representing him, did not return calls seeking comment.

Jorgensen has authority over 142 employees with a $30 million annual operating budget to pay for snow removal and the paving, drainage and maintenance of roughly 450 miles of roads and curbs in the town. He was first elected in 2010 to serve as superintendent, but has worked in the department for 37 years in various capacities, including as a foreman. He left retirement in 2009 when he was elected superintendent and was re-elected in 2013.

Smithtown Supervisor Patrick Vecchio declined to comment on the district attorney’s charges against the highway superintendent.
