Tom Treharne, longtime community development director for the City of Marion, is stepping down in early December to pursue a new opportunity in the private sector.
Treharne joined the City of Marion in 2001 as planning and development director. In 2019, he became the community development director with the merging of the Planning and Development and Building Departments. Treharne also served as interim city manager for several months in 2021 following the departure of Lon Pluckhahn.
During his time with the City, Treharne led the community’s long-term planning efforts. One of his greatest accomplishments was his role in developing the 2010 Central Corridor Plan and reimagining the former railroad right-of-way through the community. In recent years, he was able to see many of the planning efforts come to fruition with the completion of the 6th Avenue corridor and the 7th Avenue Reconstruction and Streetscape Project. Projects like the Neighborhood at Indian Creek, Tower Terrace Road, the Uptown Master Plan and the Central Plaza all happened under Treharne’s oversight.
Throughout his career, he kept the community at the forefront. Treharne was an active partner and supporter of the Marion Chamber of Commerce, Marion Economic Development Corporation and Uptown Marion District and continues to serve on the board of directors for Marion Cares, a local non-profit that focuses on helping children and families in the community.
“Much of the momentum we are currently experiencing is the product of many years of planning and establishing a bigger vision for our city,” said Marion Mayor Nick AbouAssaly. “Tom Treharne was an important part of these efforts. We thank him for his contributions and 21 years of dedicated service to the City and its residents, and wish him all the best in his future endeavors.”
Treharne and his family will remain in Marion and look forward to continuing to contribute positively to the community.
