Solar Photovoltaic Energy Project Development on Brownfields: Leveraging Policy Incentives and Project Financing Mechanisms

This study evaluates the practice of redeveloping Brownfields with solar photovoltaic renewable energy technology. Utilizing renewable energy as a strategy to reuse contaminated or potentially contaminated property is a relatively new convention. While the benefits of redeveloping Brownfields are well established, ongoing challenges and limited literature on the subject complicate the practice. Challenges, opportunities, and benefits related to renewable energy development on Brownfields are identified and analyzed. Strategic leveraging of federal, state, local, and utility incentives for renewable energy and Brownfield revitalization, and gap finance tools is explored and evaluated. A comparison of three photovoltaic Brownfield projects is analyzed for critical success and failure factors, and lessons learned. A recommendation of best practices is made based on findings and results.

The Effectiveness of Rain Gardens as a Low-Impact Development Strategy for Storm Water Pollution Reduction in Western Washington

Stormwater runoff is a major cause of surface water pollution in western Washington and cost-effective control measures are needed to reduce contamination of receiving waters. This project evaluated the performance efficiency and costs of installing a residential rain garden by inspecting two gardens and testing water quality samples in one. Infiltration through the garden was effective in reducing metals and nutrients as indicated by reductions in copper and nitrate concentrations of 75% and 97%, respectively. The costs were affordable for most homeowners and cost-effective compared to other options. After doing on-site investigations, the storm water manual for the State of Washington was reviewed and eight recommendations were made for improving it.
