Burien City Manager Michael H. Martin was granted deferred prosecution Tuesday on a drunken driving charge and will undergo two years of alcohol treatment, have an ignition interlock device installed on his car and be under court supervision for five years.

The charge against Martin will be dismissed if he undergoes the treatment and follows the other conditions during those five years, according to his agreement with King County prosecutors.

Martin, 55, was charged in May with driving under the influence of alcohol in King County District Court after he was involved in an accident on April 19 in which he allegedly drove into a planter in front of a home in the 12600 block of 14th Avenue Southwest north of Burien.

Martin was arrested after a King County sheriff's deputy said he found Martin outside his car, "leaning forward and swaying side to side." Martin's breath strongly smelled of alcohol and his speech was slurred, according to a Sheriff's Office report. He told the deputy he had consumed a couple of glasses of wine and two beers, the report said.

Martin refused field-sobriety tests or a preliminary breath test and, after being arrested, declined to submit to a Breathalyzer test, the report said.

Under state law, refusal to take a Breathalyzer test results in automatic suspension of a driver's license for at least one year. Drivers may ask for a hearing to challenge the suspension or seek approval for an alcohol-ignition interlock device.

Martin was named Burien city manager in November 2006. His yearly salary is $135,180.

He resigned in October 2005 from a top administrative job in Kent after a hit-and-run incident. He admitted to causing the accident, paid a $1,025 fine and underwent alcohol-abuse assessment, alcohol- and drug-information school and attended a victim-impact panel.
