摘要：	Many airports undertake stormwater projects to accommodate facility expansion, address obsolescence, and respond to evolving regulatory requirements. Often, stormwater infrastructure is installed or upgraded on a project-by-project and piecemeal basis, resulting in mismatches of sizes, material types, ages, and conditions. When airports are considering expanding or improving their stormwater facilities, the immediate need for stormwater infrastructure modification may not be clear, and a BCA is needed. Recently, BCAs have begun incorporating risk assessment and the triple bottom line, consisting of financial, environmental, and social considerations. Yet there has been limited guidance for addressing these factors in a BCA for airport stormwater infrastructure projects, and research was needed to address this gap. The research used to develop the guidebook was led by the Cadmus Group, LLC. The team began its research with an extensive literature review. The team then conducted interviews with stakeholders associated with stormwater projects at airports of various sizes and in differing climates and regions. Because it was difficult to identify airports that had used a BCA to select stormwater projects, the research team instead performed tabletop exercises for two airport cases of how a BCA could be employed. The research team used its findings and expertise to prepare the guidebook. The guidebook’s introduction offers an overview of the steps for conducting a BCA and common drivers for airport stormwater projects. This is followed by guidance for setting up a BCA, including framing the analysis and identifying data needs. Next, guidance is provided for incorporating a triple bottom line approach that considers capital, operations and maintenance, and financing, as well as more difficult to quantify factors such as climate resilience and regulations. A unique feature of the guidebook is the inclusion of a hypothetical example of Bayside Airport: As concepts and guidance are introduced, the guidebook demonstrates how they can be applied using the Bayside Airport example. The guidebook also features numerous checklists, flowcharts, and decision trees to help practitioners navigate the process. Lastly, the guidebook offers suggestions on how to use the BCA results, including how to make a case for the recommended alternative with stakeholders.
