Decoding the operational drivers behind transformative public space investments
Gehl grounded the evaluation plan in the Parks and Trails Portfolio strategy, developing core research questions to guide the assessment. For each sub-question, the team identified key outcome indicators and outlined methodologies for data collection and analysis. The evaluation employed a mixed-method approach, including interviews with more than 60 stakeholders across both regions. Participants represented diverse roles in park and trail development, management, and advocacy — providing a nuanced understanding of the Portfolio’s impacts, opportunities, and challenges. Thematic analysis, supported by systematic tagging and coding, enabled a structured and insightful interpretation of stakeholder perspectives.
The evaluation findings illustrate how investments in physical and social infrastructure can catalyze billions in capital projects — including two signature parks, 250 miles of regional trails, and over $100 million in endowments — across regions. The study also highlighted the five key strategies that shaped the Foundation’s park and trail development model — engage, commit, align, amplify, and collaborate — each fostering shared responsibility for implementation and long-term sustainability.
Building on both effective practices and areas for improvement identified through the evaluation, the study offers valuable lessons for leaders and partners who view parks, trails, and green infrastructure as essential to community vitality and resilience and want to bring them to life.
