Abstract To aid urban entities desiring to reduce runoff from precipitation while increasing aquifer recharge, we present an approach for simultaneously quantifying runoff and infiltration. Developing the approach involved using: (1) the Windows version of the Source Loading and Management Model (WINSLAMM) to estimate runoff from precipitation in areas with green infrastructure (GI); and (2) the SCS runoff curve method to estimate infiltration. Computed infiltration and runoff values enable the estimation of the runoff reduction and infiltration increase due to alternative GI construction modes. We relate infiltration ratios to land use for a range of event rainfall depths in southwestern USA. These ratios can aid estimation of aquifer recharge while improving storm water management. We apply the approach to a Salt Lake City residential area for current land use and three assumed runoff control practices. Although currently applicable for a wide range of precipitation and urban land use situations in southwestern USA, the approach is extensible to guide urban development elsewhere.

<em>Abstract.</em>—Relations between stream habitat and urban land-use intensity were examined in 90 stream reaches located in or near the metropolitan areas of Salt Lake City, Utah (SLC); Birmingham, Alabama (BIR); and Boston, Massachusetts (BOS). Urban intensity was based on a multi-metric index (urban intensity index or UII) that included measures of land cover, socioeconomic organization, and urban infrastructure. Twenty-eight physical variables describing channel morphology, hydraulic properties, and streambed conditions were examined. None of the habitat variables was significantly correlated with urbanization intensity in all three study areas. Urbanization effects on stream habitat were less apparent for streams in SLC and BIR, owing to the strong influence of basin slope (SLC) and drought conditions (BIR) on local flow regimes. Streamflow in the BOS study area was not unduly influenced by similar conditions of climate and physiography, and habitat conditions in these streams were more responsive to urbanization. Urbanization in BOS contributed to higher discharge, channel deepening, and increased loading of fine-grained particles to stream channels. The modifying influence of basin slope and climate on hydrology of streams in SLC and BIR limited our ability to effectively compare habitat responses among different urban settings and identify common responses that might be of interest to restoration or water management programs. Successful application of land-use models such as the UII to compare urbanization effects on stream habitat in different environmental settings must account for inherent differences in natural and anthropogenic factors affecting stream hydrology and geomorphology. The challenge to future management of urban development is to further quantify these differences by building upon existing models, and ultimately develop a broader understanding of urbanization effects on aquatic ecosystems.

Rail Service

Transit-oriented developments are touted as providing a variety of social benefits, but personal benefits to residents are underresearched. The authors surveyed 51 residents before and after a new light rail stop was constructed in their revitalizing Salt Lake City neighborhood. Residents anticipated and then later experienced increased housing and neighborhood economic values, enhanced sense of community, and improved neighborhood reputation. Residents experienced greater than anticipated pedestrian and child safety after rail service started. Compared with resident perceptions of walkable neighborhoods elsewhere, the Salt Lake residents perceived their neighborhood to be denser, and offering less land-use diversity and more crime safety problems. Perceived walkability increased, with residents reporting greater land-use diversity and neighborhood satisfaction after rail stop completion. However, residents said more stores, parks and trails, and trees would improve walkability. These results show the personal benefits residents desire to make transit-oriented living a satisfying residential alternative.

Literacy Resources

The pathway to successful medical innovation includes a labyrinth of business hurdles including regulatory approval, reimbursement strategy, intellectual property, and marketing challenges. Early consideration of these factors informs critical decisions in the biomedical engineering (BME) design process that minimize product and business risks. Information literacy training provides students with strategies for discovering the wide range of resources for biomedical engineering design. This expanded knowledge base can be leveraged to generate more fully realized solutions that may improve commercialization success and decrease time to market, ensuring the medical innovations more quickly reach patients and healthcare providers.This poster presents a cohort study of BME students who matriculated through an expanded information literacy program. This updated information literacy curriculum, implemented in two phases over two academic years, exposes students to the complex environment surrounding innovative design in healthcare broadly, and medical device design in particular. This additional component of the design project requires BME students to consult and cite a diverse array of information sources within their project documentation, including patents, business intelligence, legal proceedings, FDA regulatory information, as well as insurance reimbursement and medical bill coding.
