The Sammamish City Council unanimously elected Don Gerend as mayor and Ramiro Valderrama-Aramayo as deputy mayor Tuesday.

The city runs on a council-city manager form of government; the seven-member council elects the mayor.

Gerend, the longest sitting council member, has been on the council since the city incorporated in 1999. He’s been selected as the city’s mayor several times before. Gerend, who will be up for re-election in 2017, will serve as mayor for the next two years.

Valderrama-Aramayo was first elected to the council in 2011 and has previously served as deputy mayor. He was re-elected to the council in the November 2015 election.

Valderrama-Aramayo and the other two elected in November 2015 — Tom Hornish and Christie Malchow — were sworn in at the Tuesday meeting.
