Abstract
Wilmington, Delaware, the state’s largest city with a population of 70,000, faces critical challenges with its aging combined stormwater and sewer systems, exacerbated by rising sea levels and intensified storm events. Severe flooding from Hurricane Ida underscored these vulnerabilities, disproportionately impacting underserved communities and highlighting the urgent need for enhanced infrastructure resilience. As a result, increased funding and initiatives have been directed to green stormwater infrastructure (GSI) including bioswales, green space, and permeable pavement. This study focuses on Northeast (NE) Wilmington, a neighborhood situated along the Brandywine Creek that is poised for redevelopment but faces significant flood risks. This study aims to identify: 1) existing plans for GSI in the NE; 2) perceived challenges related to flooding and stormwater management; 3) proposed and possible solutions to address challenges related to GSI. To do this, we reviewed 4 urban plans for the Northeast and the city. Inductive and deductive coding techniques were employed to systematically analyze all texts.
Findings emphasize the need to update Wilmington’s current stormwater management and propose that while GSI cannot replace comprehensive system upgrades, it can mitigate flood impacts and enhance neighborhood aesthetics. GSI is desirable within the community and can bolster economic vitality and reduce health risks. Furthermore, the equitable distribution of green infrastructure should be a central consideration in the design process to ensure that all communities benefit from these improvements. As Wilmington undergoes redevelopment, prioritizing effectiveness in planning new infrastructure is crucial for fostering economic growth and resilience of all areas, especially in light of intensifying climate stressors. With this in mind, community involvement and expert input are pivotal in determining optimal locations and types of green stormwater solutions that align with community needs and preferences. Thus, future research will include interviews with community leaders and hydrological modeling to further refine these strategies.
