Peachtree Drive is officially Boucher Drive in honor of 92-year-old Leon Boucher and his late wife.
The access road to Conklin Park is a stone's throw from the house where Boucher has lived since 1955.
Service crews erected the sign during a ceremony Nov. 5, the day after City Council approved a resolution renaming the drive.
"This is the best place you can be," Boucher said Nov. 4 after accepting a copy of the resolution from Council President Brett Sciotto.
Boucher said about 650 people lived in the city when he and his wife, Virginia, moved into their Conklin Drive residence.
Former Hilliard Mayor Roger Reynolds and his wife, Phyllis, suggested that Bill Uttley, one of the new City Council members to be seated in January, propose the resolution.
The Reynolds' son, Dave, spoke on behalf of the Boucher family. Virginia Boucher died Oct. 14.
In the early 1960s, Boucher, his wife and their two children, Dave and Carole, traveled to developing nations throughout the world.
Boucher, who has a doctorate degree in agriculture from Ohio State University, assisted teams in creating clean water systems and sustainable agriculture systems.
Reynolds described the Bouchers as "one of the humblest couples one would ever meet."
A World War II veteran, Mr. Boucher also was a professor at Ohio State and a teacher in Hilliard schools.
