ASLA 2011 Student Awards Research Category Descriptive Data Summary Entry Number: SA-593G Level of Study: Graduate Individual or Team Entry: Individual Project Title: South Grand Boulevard: user orientation as a catalyst for resiliency Project Statement: The economic and environmental costs of aging stormwater infrastructure are increasing in cities all across this country and world. This study proposes a new theoretical framework that identifies how and at what time the introduction of ecological processes into the urban right-of-way is likely to be successful in the long-term. From this research, it is possible to design streets that surpass current “green street” and “complete street” initiatives and achieve a high level of resiliency. Project Narrative: Introduction Contemporary design of the urban environment focuses increasingly upon the quality of space found within the public right-of-way. Landscape architects and urban planners are beginning to ask new questions that deviate from the conventional streetscape designs of the latter half of the 20th century. Under the mantra “complete the streets,” communities all across America are calling for a paradigm shift towards multimodal, pedestrian-scaled urban rights-of-way. At the same time, existing stormwater and combined sewer infrastructure is nearing the end of its productive lifespan in cities all across the country and world. The direct costs associated with repairing this infrastructure combined with the indirect costs of poor water quality and a greater frequency and intensity of flooding events downstream present a strong argument for developing new, innovative ideas about how to best design tomorrow’s infrastructure. The reintegration of ecological processes into the urban fabric will act as a catalyst for the appreciation of genius loci (spirit of the place) and user meaning while mitigating downstream flooding, increasing water quality, and extending the lifespan of existing stormwater infrastructure. By studying the hierarchical categorization of urban rights-of-way according to increased levels of user orientation, this research project aims to clearly articulate a new theoretical framework for expanding upon the current discourse surrounding “complete streets” and “green streets” theory. In early 2006, the East-West Gateway Council of Governments introduced the St. Louis Great Streets Initiative with the goal of promoting “complete street” design principles in St. Louis, Missouri. South Grand Boulevard, selected as one of four pilot projects, seeks to be a demonstration project for socially and economically sustainable streets in the region; however, current concepts are not progressing far enough towards providing a model of future infrastructural design. With the allocation of $2.7 million of federal stimulus money towards the project, a huge opportunity presents itself for testing the Hierarchy of User-oriented Streets framework as a viable model for solving the stated dilemma. Hierarchy of User-oriented Streets Framework Innovation often comes through stepping outside the typical boundaries of the design professions to look at theories developed within other fields of research. During the 1940s and 1950s, a psychologist named Abraham Maslow was studying the differences among human needs as a way to understand what motivates human behavior. Through his research, he realized that some needs take precedence over others acting as prerequisites for attaining higher level needs. In a day when supervisors viewed their factory workers as “replaceable parts,” Maslow’s Hierarchy of Needs Framework proved to be a successful utility for increasing the productivity of workers. He discovered that as supervisors satisfied the
ASLA 2011 Student Awards Research Category Descriptive Data Summary higher-level needs of their workers, they would respond with greater outputs. Drawing a strong parallel, this study asks the question: How can identifying a hierarchy of user-oriented street types lead to greater productivity, therefore resiliency, in the design, construction, and maintenance of urban rights-of-way? While this question prompted the initial idea of formulating the proposed framework, the articulation of five distinct levels, their definitions, the associated subcomponents, contemporary urbanisms, and street design movements all came from a rich exploration of existing literature. Notable sources of literature include Echols and Pennypacker’s “From Stormwater Management to Artful Rainwater Design” (2008), Lynch and Hack’s Site Planning (1984), Meyer’s “Sustaining Beauty” manifesto (2008), Mossop’s “Landscapes of Infrastructure” (2006), Olin’s “Form, Meaning, and Expression in Landscape Architecture” (1988), and Treib’s “Must Landscapes Mean?” (1995). The Hierarchy of User-oriented Streets framework contains five levels: function, safety, ecology, genius loci, and meaning. Function is the lowest level of user-orientation in which an urban right-of-way provides the most basic levels of service to users for their efficient movement from one point of reference unto another. Safety is the next to lowest level of user-orientation in which an urban right-of-way promotes equal opportunity and experience through the health, safety, and welfare of all users. Ecology is the essential, median level of user-orientation in which an urban right-of-way reintegrates natural processes into the urban fabric through eco-technologies that promote healthier environments and an improved quality of life for the users. Genius loci is the next to highest level of user-orientation in which an urban right-of-way uses ecological processes through time to engender its distinctive character and unique identity toward a community of users. Meaning is the highest level of user-orientation in which an urban right-of-way cultivates educated “dynamic users” who voluntarily take ownership of the public space and engage in actions that promote resiliency within the corridor. Similar to Maslow’s framework, a street must fulfill the lower levels before higher levels can be attained. Methods
This study investigated four precedents: SW the 12th Avenue Green Street (located in Portland, Oregon), the 12th Street Rain Gardens (located in Kansas City, Missouri), St. Charles Avenue (located in New Orleans, Louisiana, and Stephen Epler Hall (located at Portland State University). In order to further develop the ideas represented in the proposed framework, each of the selected precedents were qualitatively evaluated using the framework as a metric. The specific methods for this assessment included using a coded imagery analysis to identify individual components with the appropriate level of the framework. During the precedent study, the theoretical framework established a set of criteria with which to evaluate three precedent projects and one existing place. Because of its utility, the framework was employed for organizing the site inventory and analysis; however, this time, it was used as a point of departure for generating specific methods rather than serving as a metric for evaluation. Seeking to maintain the hierarchical ordering within the proposed framework, the site analysis methodology consistently categorizes each of its steps into the five framework divisions of function, safety, ecology, genius loci, and meaning. In this way, landscape architects and urban planners can look to this study as a guide for which type of analysis questions they should ask depending on where their project is intended to hit upon the framework. If your end goal is to design a “complete street,” there is little to no reason for you to spend time analyzing hydrological watersheds and existing impervious surfaces. These are two examples of site analysis tasks found within the ecology level of the proposed framework. Only in designing a “green street,” “destination street,” or “resilient street” would you address these tasks. Higher level analysis is not needed for a lower level design. The first step of the site analysis methodology included completing a user analysis for each level of the theoretical framework. Following the user analysis, three project goals were selected for each level of the framework. While these goals would eventually be used to guide the conceptual thinking for design explorations, they served an immediate function to break down the subcomponents of each level of the
ASLA 2011 Student Awards Research Category Descriptive Data Summary framework for the development of site appropriate programmatic elements. An ongoing literature review and precedent study feedback loop aided in the selection of additional programmatic elements for South Grand. The next step in the methodology formalized specific analysis questions that related and referenced the given user group, project goals, and programmatic elements to South Grand as an existing site. In many cases, these questions were quite complex requiring the formalization of subsequent inventory questions to further delineate an appropriate path of inquiry for answering the original question. In the end, task sheets outlining the inputs, source data, methods, and potential outputs were assembled to guide the production work of South Grand’s inventory and analysis. Results The application of the framework to the design proposal for South Grand yields several unique, site appropriate design strategies. At the function level, the design strategies include transforming the arterial corridor from four travel lanes to two travel lanes separated by a middle turn lane and incorporating concrete wet vaults underneath the sidewalk. In addition to serving many ecology-related services, the wet vaults protect the limestone foundations of the adjacent buildings from unwanted subsurface water. At the safety level, design strategies include raised intersections acting as “speed tables,” a dispersion of bike parking throughout the district, radiant heating of sidewalk and on-street parking spaces, extra-wide parking stalls for users with disabilities, and a 3” tall safety curb around all stormwater infiltration planters. At the ecology level, design strategies include stormwater infiltration planters and a significant investment in the district’s urban forest. Disregarding soil infiltration rates, the stormwater planters can accommodate 9,410 cubic feet (CF) of the total runoff volume leaving 5,489 CF to enter into the underground wet vaults. In terms of the investment in the urban forest, this study’s design proposal for South Grand, obtains a net annual benefit of $12,255.18 (Davey Resource Group 2009). This is a substantial increase in value as the existing urban forest is only valued at a net annual benefit of $3,920.62. At the genius loci level, design strategies include painted spherical bollards at the raised intersections, electric car charging stations, the use of local materials, expressive paving patterns, and the incorporation of lighting into the stormwater planters. Finally, at the meaning level, design strategies include incorporating a cast iron pump within the right-of-way to provide users the opportunity to physically interact with the eco-technologies and the design of an interactive and educational pocket park intended to encourage the development of a “community of users” and a “user land ethic.” Conclusions In this study, the proposed framework was utilized throughout the precedent study, the site inventory and analysis, the development of program, the design proposal, and the project evaluation. As evidenced through its application at South Grand, the incorporation of this framework into one’s design process yields a substantial return towards attaining resiliency in urban rights-of-way. The Hierarchy of User-oriented Streets framework provides the road map for how landscape architects and urban planners can lead the movement that transforms our cities’ infrastructure from functional thoroughfares to resilient places. Future Research Two important opportunities exist for future research in relation to this study. First, future investigations could establish performance baselines for each level of the framework allowing for a quantified measure of success. Second, though presented within the scope of urban rights-of-way, the proposed framework could be easily adapted to other project types (parks, golf courses, community planning, suburban sprawl, gardens, greenways, brownfield sites, etc.) as a design process model that effectively addresses the creation of productive, resilient landscapes.

Proposed master plan for southern portion of project site: Design area included the public right-of-way along South Grand Boulevard and the conversion of an underutilized surface parking lot into an educational pocket park.

Detail plan of street block containing the educational pocket park: The adjacent parcel was selected as an underutilized parcel most suitable for conversion. One of the primary factors was its current ownership by the city of St. Louis.
Coded imagery analysis for detail plan of street block: This coded application of the framework to the design imagery reveals that function, safety, and ecology are easier to accomplish within the narrow right-of-way than genius loci and meaning.
Perspective view from within the educational pocket park: The design of the park promotes user interaction with the site and the development of a “community of users.”
