The urban thermal environment varies not only from its rural surroundings but also within the urban area due to intra-urban differences in land-use and surface characteristics. Understanding the causes of this intra-urban variability is a first step in improving urban planning and development. Toward this end, a method for quantifying causes of spatial variability in the urban heat island has been developed. This paper presents the method as applied to a specific test case of Portland, Oregon. Vehicle temperature traverses were used to determine spatial differences in summertime ~2 m air temperature across the metropolitan area in the afternoon. A tree-structured regression model was used to quantify the land-use and surface characteristics that have the greatest influence on daytime UHI intensity. The most important urban characteristic separating warmer from cooler regions of the Portland metropolitan area was canopy cover. Roadway area density was also an important determinant of local UHI magnitudes. Specifically, the air above major arterial roads was found to be warmer on weekdays than weekends, possibly due to increased anthropogenic activity from the vehicle sector on weekdays. In general, warmer regions of the city were associated with industrial and commercial land-use. The downtown core, whilst warmer than the rural surroundings, was not the warmest part of the Portland metropolitan area. This is thought to be due in large part to local shading effects in the urban canyons.
As a result of three workshops within each community, the residents brought forth ideas that they want to see implemented to increase their thermal comfort and safety during extreme heat days. As depicted below, residents’ ideas intersected around similar concepts, but specific solutions varied across neighborhoods. For example, all neighborhoods would like to add shade to their pedestrian corridors but preferences for the location of shade improvements differed. Some neighborhoods prioritized routes to public transportation, others prioritized routes used by children on their way to school, and others wanted to see shaded rest stops in key places. Four overarching strategic themes emerged across all three neighborhoods: advocate and educate; improve comfort/ability to cope; improve safety; build capacity. These themes signal that there are serious heat safety challenges in residents’ day-to-day lives and that community, business, and decision-making sectors need to address those challenges.
Heat Action Plan elements are designed to be incorporated into other efforts to alleviate heat, to create climate-resilient cities, and to provide public health and safety. Heat Action Plan implementation partners are identified drawing from the Greater Phoenix region, and recommendations are given for supporting the transformation to a cooler city.
To scale this approach, project team members recommend a) continued engagement with and investments into these neighborhoods to implement change signaled by residents as vital, b) repeating the heat action planning process with community leaders in other neighborhoods, and c) working with cities, urban planners, and other stakeholders to institutionalize this process, supporting policies, and the use of proposed metrics for creating cooler communities.
The intent of this study is to develop a new eco-cultural design model of development for the Salt River watershed and surrounding areas with renewed respect for the land in modern society. It includes both conceptual and practical community guides to facilitate and catalyze a new community-driven typology of planning prepared for rapid community change and climate challenges. This study includes the review of prominent existing projects, both regionally and globally, with expertise in the areas of urban development, culture and place keeping/making, ecology and water management. This study aims to exhibit the diverse components of urbanism and its effects on the Salt River corridor, surrounding urban ecosystems and climate. This thesis argues for simultaneous and codependent cultural and ecological growth and healing, and its necessity for sustainable urban development. Lastly, an urban revitalization framework is manifested in a community-oriented handbook based on key findings to produce a unified vision executed by watershed community co-design of the Phoenix metropolitan area.
Preventing heat-associated morbidity and mortality is a public health priority in Maricopa County, Arizona (United States). The objective of this project was to evaluate Maricopa County cooling centers and gain insight into their capacity to provide relief for the public during extreme heat events. During the summer of 2014, 53 cooling centers were evaluated to assess facility and visitor characteristics. Maricopa County staff collected data by directly observing daily operations and by surveying managers and visitors. The cooling centers in Maricopa County were often housed within community, senior, or religious centers, which offered various services for at least 1500 individuals daily. Many visitors were unemployed and/or homeless. Many learned about a cooling center by word of mouth or by having seen the cooling center’s location. The cooling centers provide a valuable service and reach some of the region’s most vulnerable populations. This project is among the first to systematically evaluate cooling centers from a public health perspective and provides helpful insight to community leaders who are implementing or improving their own network of cooling centers.
The project is divided into four sections. The first section explores what Sensory Processing Disorder is, how Occupational Therapy with Sensory Integration positively impacts healing processes, and how designers can expand this processing into the natural healing environment of the great outdoors in a toxic and urbanized world. The second section discusses the vision, goals and objectives for implementation of Sensory Design Guidelines as discussed in the third section. And finally, the fourth section provides a conceptual example of what SDG would look like when applied to a physical site along a natural corridor in a densely urbanized landscape.
The final example of SDG implementation is applied to a site along the Salt River (Rio Salado) Corridor in Phoenix, Arizona. The Corridor is the subject of a coordinated inter-agency public/private restoration initiative spanning more than fifty-five miles along the Salt River that has been strongly supported by former U.S. Senator John McCain and greatly influenced by active involvement from Arizona State University students. The designated example site is designed as one site to be utilized in a larger network of easily accessible Sensory sites, each to be designed with a different approach to sensory development, as well as variation in challenges based on age and sensory abilities. Guidelines are intended to work in conjunction with future local projects promoting social and ecological growth and wellbeing, such as the Phoenix site is intended to work in conjunction with future Rio Re-imagined projects.
The findings, guidelines, and examples provided throughout the paper are focused on re-inventing the relationship between the built and natural environments in the urbanized landscape into one of daily nature-engagement and can be applied to any group living within an urban setting. By designing for society’s most vulnerable populations, design application benefits not only the individual, but creates a resilient, healthy environment for the entire urban population today, and for future generations.
have on the environment and how to enhance the sense of place by investigating
ecoregional design for now and for the future. The specific site where examples of
sustainable design will be implemented is at the proposed new Arizona State University
Track and field that will be relocated as part of the Novus Innovation Corridor Athletic
Village. First, we will discuss the impact sports have on our health and culture and why
athletics matters to society. Understanding the history of track and field and the
evolution of track stadiums and looking at current designs of stadiums will provide
insight for future track designs. Next, we will look at some existing track stadiums
around the United States and how each design is adjusted to the climate and weather of
the region to help the stadium last longer and be more sustainable. After that, we will
look at what is working for the existing Sun Angel Stadium and what should be improved
and implemented in the new design. Lastly, we will explore a proposed design for the
new Sun Angel Track Stadium and how it will benefit the student athletes, spectators,
and the environment.
