John Brick, who has been administrator of the tiny island city of Jamaica Beach since 2000, will retire in April.
Brick, 78, announced his retirement during a city council meeting Monday.
"It's just time to get fresh faces, fresh people, fresh ideas," Brick said Thursday.
Jamaica Beach is an independent city in the middle of Galveston Island. Its estimated population is about 1,065, according to the U.S. Census Bureau.
The city's population dropped to less than 1,000 after Hurricane Ike in 2008, but has now returned to its pre-hurricane levels.
Brick said the city had grown during his tenure, citing the construction of new city buildings and a public pool.
"I don't think it's Mayberry anymore," Brick said, comparing the community to the tiny town in "The Andy Griffith Show."
Brick plans to stay with the city through part of April, as the council searches for his replacement. Advertisements for the job were expected to be published Friday.
Brick earned $105,433 in salary during the past fiscal year, according to city records.
