Our speaker was Thomas Woltz, the landscape architect with Nelson Byrd Woltz (NBW), responsible for the Memorial Park renovation plan, including the Eastern Glades and the land bridge currently under construction. Mr. Woltz discussed the role of landscape architecture in designing equity and community wellness in civic spaces. In his role as Principal of NBW, Thomas and his team have developed a body of work that responds to complex ecological systems and amplifies the historical and cultural narratives of the landscape.
Around 1975 after Ima Hogg passed away, Sadie Gwin Blackburn was one of the primary citizens who rallied to protect Memorial Park. Also, in 1990, she was one of the founders of the Memorial Park Conservancy.
It is, therefore, fitting that Mr. Woltz will discuss the amazing transformation of Memorial Park and two additional NBW projects for the 32nd Annual Sadie Gwin Blackburn Seminar.
We hope you will join us!
