Located in Wilmington, Delaware, along the shoreline of the Brandywine Creek in the Greater Philadelphia/Delaware River Watershed, this project responds to a specific and critical need for the site as prioritized by multiple stakeholders. The project applies an innovative approach for quantifying increased flood resilience while simultaneously reducing contamination levels through the implementation of green infrastructure. To solve joint issues related to increased flood risk concurrent with higher potential for exposure to environmental contaminants transported in flood waters from adjacent industrial sites, brownfields, and combined sewer overflows, the research team develops a phased approach to decreasing stormwater runoff and pollutant loads on a 130-acre (52.6 hm2) site along the Brandywine Creek, applying the Long-Term Hydrologic Impact Assessment (L-THIA) model to quantify design impacts and performance of a master plan. Overall, the proposed master plan can reduce stormwater runoff and pollutant loads to levels significantly less than existing conditions or the current land use plan. Further, this research is unique in that it uses outputs from the L-THIA to compare existing conditions, effects of the current comprehensive plan, and impacts related to the proposed neighborhood-scaled master plan to evaluate the effectiveness between each scenario.

Many urban areas affected by flood disasters are also becoming increasingly ecologically and socially fragmented due to the accumulation of vacant properties. While redevelopment is often viewed as the primary objective in regenerating vacant properties, they can also potentially provide ecological and hydrological land uses. Rather than chasing development- based incentives for regenerating vacant lots in high flood-risk communities, a balance should be sought between new developmental land uses and green infrastructure to help counteract stormwater runoff and flood effects, or "Resilience through Regeneration." This paper uses landscape performance measures to evaluate the economic and hydrologic performance of green infrastructure regeneration projects for three marginalized neighborhoods in Houston, Texas, USA. Each project site is characterized by excessive vacant lots and flood issues. Results suggest that, when using green infrastructure to regenerate vacant properties, 1) flood risk continually decreases, 2) upfront economic costs increase in the short term (when compared to conventional development), and 3) the long-term economic return on investment is much higher.

This project is to develop a comprehensive master plan incorporating key principles of sustainable urbanism for a business district in Houston, Texas, USA. The main design objectives are to create a livable and sustainable urban business center, to promote economic growth and to implement a streetscape design guideline to promote walkability and bikeability.
