Steamboat Springs Stuart Orzach, president of the board of the Community Alliance of the Yampa Valley, resigned his seat on the board this week.
A new president will be elected Feb. 1. Members of the Community Alliance are in the process of taking nominations.
Orzach did not return calls for comment on Thursday.
"Stuart was the smartest, brightest, hardest-working man we've had," Alliance member Bob Enever said.
"I'll be sorry to see him go, but I'm sure he'll continue working on the issues."
Orzach became a public figure over the past two years. He spoke at numerous Steamboat Springs City Council meetings on issues ranging from the county's bid for a new courthouse to Triple Crown softball.
Orzach described the function of the Community Alliance in a letter written to the Steamboat Pilot & Today in November 2001.
"Our role is to have productive relationships with all city and county officials to carry out our goals of encouraging the community to support growth control measures and to protect the environment," he wrote.
