Riverfront Park Flagpole Garden
Redesigned, replanted and rededicated July 21, 2016. The project made possible by a generous donation by the family of Florence Weck who passed away in 2014 and a member of the club since 1962. She followed in the steps of her mother, Irma B. Ritt Ebel, who was a 1929 charter member of the garden club. A plaque in honor of Florence was placed at the flagpole garden memorializing her many years of dedication and service.
