Evidence shows that green infrastructure planning relies on technocratic and economic valuation approaches to protect lands of high monetary value against flooding without considering climate justice. Contrasting epistemic justice against recognition and socio-cultural valuation of ecosystem services, this study explores how flood adaptive green infrastructure planning may recognize and include the local experiential knowledge of underrepresented groups. We focus on Thorncliffe Park, a dense tower neighborhood with a low-income immigrant population in Toronto, Canada, to explore: (1) the local experiential knowledge of residents about floods, climate-adaptive green infrastructure, and structural vulnerabilities; (2) the root causes of epistemic injustice in previous adaptive green infrastructure interventions; (3) siting options for future adaptive green infrastructure. The methodology includes 199 online surveys-among Thorncliffe Park's residents and 20 in-depth interviews with local community leaders and Toronto-based planning experts, policy reviews. Additionally, a spatial component consists of 120 online participatory mapping activities and spatial analysis of surface run-offs. Our findings-reveal that Thorncliffe Park residents are excluded from adaptive green infrastructure planning because flood management-remains a technocratic process-grounded in economic valuation approaches and technical justifications. Our findings-indicate that decision-makers have not credited residents' needs and testimonies over decades due to-historical racial and socio-economic prejudice toward Thorncliffe Park's residents. We also-identify four hermeneutical barriers that prevent residents from impacting decisions, namely a lack of: social networks, citizenship rights, climate awareness opportunities, and communicational tools.
