Description
This report is the consolidated work of an interdisciplinary course project in CEE494/598, CON598, and SOS598, Urban Infrastructure Anatomy and Sustainable Development. In Fall 2012, the course at Arizona State University used sustainability research frameworks and life-cycle assessment methods to evaluate the comprehensive benefits and costs when transit-oriented development is infilled along the proposed light rail transit line expansion. In each case, and in every variation of possible future scenarios, there were distinct life-cycle benefits from both developing in more dense urban structures and reducing automobile travel in the process.
Results from the report are superseded by our publication in Environmental Science and Technology.

Description
The rate of urbanization has been impacted by global economic growth. A strong economy results in more people moving to already crowded urban centers to take advantage of increased employment opportunities often resulting in sprawling of the urban area. More natural land resources are being exploited to accommodate these anthropogenic activities. Subsequently, numerous natural land resources such as green areas or porous soil, which are less flood-prone and more permeable are being converted into buildings, parking lots, roads and underground utilities that are less permeable to stormwater runoff from rain events. With the diminishing of the natural landscape that can drain stormwater during a rainfall event, urban underground drainage systems are being designed and built to tackle the excess runoff resulting from urbanization. However, the construction of a drainage system is expensive and usually involves massive land excavations and tremendous environmental disturbances. The option for constructing an underground drainage system is even more difficult in dense urban environments due to the complicated underground environments, creating a need for low footprint solutions. This need has led to emerging opportunities for low impact development (LID) methods or green infrastructures, which are viewed as an environmentally friendly alternative for dealing with stormwater runoff. LID mimics the pre-development environment to retain the stormwater runoff through infiltration, retention, detention and evaporation. Despite a significant amount of prior research having been conducted to analyze the performance of runoff volume reduction and peak flow decrement of various green infrastructures, little is known about the economic benefits of using LID practices.
This dissertation fills the gap in the knowledge regarding the life-cycle-cost effectiveness of green infrastructure in current urban developments. This study’s two research objectives are:
(1) Develop a life cycle cost calculation template to analyze the cost benefits of using LID compared to the traditional drainage system
(2) Quantify the cost benefits based on the real-world construction projects
A thorough literature review led to the data collection of the hydrological benefits of using LIDs in conjunction with overviewing three real-world construction projects to quantify the cost benefits of LIDs.

Description
Stern Produce has been a prominent agricultural produce distributor in Arizona since 1917, with three distribution locations in the state: Phoenix, Tucson and Flagstaff. The company is a wholesale supplier of produce, meat and dairy products. Stern Produce is seeking to create comprehensive sustainability metrics to develop sustainability baseline information on their operations. This project, in partnership with Stern Produce’s Sustainability Coordinator, provides a final report that describes the sustainability indicators and metrics, provides recommendations for future growth, and highlights immediate areas of impact using the Hart and Milstein’s Sustainable Value Framework (2003). Under the three tenets of people, earth and business, the sustainability areas to focus on for Stern Produce are: sustainable procurement (internal and external); fleet management; organizational continuity; sustainable communities; and, sustainable building operations. By formulating sustainable focus areas, Stern Produce is acknowledging the significance of integrating environmental consciousness with economic performance and social benefits. Based on the findings, the project will assist Stern Produce in identifying intervention points and find new ways to mitigate negative operational outputs. Moreover, the project will facilitate cross-department engagement and involvement, provide data for sustainability key performance indicators, and further social commitments to operating sustainably. Measuring and reporting operations also improve transparency within the company and with external partners. Furthermore, the assessment proposes sustainability initiatives to address staff and community wellbeing concerns. Thus, the project uses a triple-bottom line approach to assess Stern Produce and translate the sustainability indicators into value for the company.
