Enhancing Urban Resilience: The Impact of Tree Planting on Stormwater Management and Heat Island Reduction in Baltimore

Abstract Submission: Climate change is causing increasingly severe weather events, such as heatwaves and intense storms, which excessively affect vulnerable communities in Baltimore City. This research explores the integration of tree planting into stormwater management systems as a strategy to mitigate these impacts. The study focuses on evaluating the performance of existing stormwater management practices and analyzing the co-benefits of tree canopy coverage in enhancing these systems. Utilizing PCSWMM simulations, various tree-planting scenarios are modeled at Broadway East Baltimore to assess their impact on stormwater management and urban heat island effects. The analysis reveals that increasing tree canopy coverage significantly improves stormwater management by enhancing infiltration, reducing surface runoff, and mitigating flood risks. Additionally, the presence of trees helps lower urban temperatures and improve air quality, offering critical cooling benefits and contributing to overall public health. The results underscore the dual advantages of incorporating green infrastructure into urban planning, demonstrating that tree planting not only addresses stormwater challenges but also enhances climate resilience and sustainability. This research provides valuable insights for policymakers and urban planners aiming to integrate nature-based solutions into climate adaptation strategies.
