This paper presents the Public-Space Toolkit for Hudson, a framework designed to enhance community engagement, accessibility, and equity in public spaces. Grounded in place-keeping principles, the toolkit ensures that public-space improvements prioritize affordability and inclusivity while mitigating displacement risks. Using Warren Street pocket parks as a pilot intervention, this study demonstrates how small-scale, community- driven urban strategies can foster long-term sustainability. The toolkit integrates equity impact assessments, zoning protections, and participatory governance models to prevent gentrification while supporting economic and cultural vibrancy. Drawing on case studies from comparable small cities, it outlines scalable policy recommendations for future applications in Hudson and beyond. By embedding equity within planning processes, this model offers a replicable approach for cities seeking socially just and resilient public spaces.
