Part of a civil engineer’s duty is to seek opportunities for constructive service in civic affairs and work for the advancement of the safety, health, and well-being of their communities. Public engagement (PE) with engineering projects is the ideal vehicle for engineers to perform this civic duty. Interest in PE for public infrastructure projects has increased due to the emphasis placed on the societal impacts of infrastructure projects and the need to insure all groups, especially underserved ones, have a voice in the process. Many resources describe effective PE practices, but there are a limited number of metric-based frameworks to evaluate their effectiveness. Urban greenways are prime transportation infrastructure for investigating PE effectiveness due to reliance on public feedback and public funding. The duration of these projects and the need for consistent engagement allow for the testing of various PE strategies and offer the ability for benchmarking and corrective measures to be implemented after initial assessment. Comparative multi-case studies will be used to create an evaluation framework to assess the effectiveness of PE efforts for urban greenway projects by applying the analytical framework of Structure Public Involvement (SPI) designed for transportation infrastructure. This project is not funded.
