In 1968, when Luke Melchert took a job as Chaska's city attorney, the city was a flood-prone, far-flung backwater with a population of about 4,000.
He stayed in that position more than half a century, a key figure in projects expanding the city that today has nearly 28,000 residents.
Last month, at age 82, Melchert announced his retirement.
"He's got the context and perspective on community development that are really rare to find," said City Administrator Matt Podhradsky. Melchert understands "how it all fits together," he said.
Bob Roepke, who was Chaska mayor from 1984 to 2002, called Melchert "the resident active historian of city development."
Known for never missing a City Council meeting, Melchert could have retired in the early 2000s. But he had no interest in stepping down at 65.
"You're a young person at that age," he said. "To be part of watching a city grow, at a job I liked — why retire?"
Chaska has grown in more than population; it offers more than 10 times as many local jobs as it did in 1970, according to the Metropolitan Council. It also — again, thanks in part to Melchert's efforts — is much easier to travel to or from. His efforts in negotiations for federal funding and land acquisition helped launch the long-awaited construction of Hwy. 212 as a four-lane freeway to Chaska and sped residents' commutes to Minneapolis and other parts of the metro.
