The Hawthorn Park Enhancement Project, managed by Eric Diehl and supported by project engineers Daniel Conley and Andy Bolyard, focuses on improving key aspects of the park located in Indiana, previously owned by the Hulman Family. Recent progress includes thorough investigations of Burns Lake Dam, hydrologic studies, and compliance with Indiana dam regulations. Future directions aim to enhance trail connectivity, assess spillway adequacy, and design necessary safety improvements. Ultimately, the project seeks to ensure a sustainable and safe environment for park visitors.
