The 11th Street Bridge Park will be Washington, D.C.’s first elevated public park and a new venue for healthy recreation, environmental education, and the arts. As a result of a unique partnership with the Landscape Architecture Foundation (LAF), park managers now have a set of metrics and recommendations to track performance towards the park’s key objective of improving the surrounding environment.
Expected to open by late 2019, the park will be built on the piers of the old 11th Street Bridge spanning the Anacostia River. The park is being designed by OMA+OLIN, the team that won a seven-month design competition. The park vision, design, and desired impacts have been informed by an extensive community outreach and consultation process.
Over the past year, LAF partnered with the 11th Street Bridge Park staff to document environmental performance goals and objectives, make recommendations to collect baseline information, and propose a set of metrics and methods that can be used to effectively evaluate the Bridge Park’s performance once it is built and operating. Many of these metrics can also be used to test scenarios and inform the design of the space.
The report draws on LAF’s seven years of experience measuring and documenting the performance of exemplary landscape projects for its Landscape Performance Series. It represents an important, but often overlooked, first step in the performance evaluation process: thinking about and documenting how success will be defined and measured. This should be done from the earliest stages of a project and refined throughout the design process.
LAF hopes that this partnership with 11th Street Bridge Park can serve as a model for how landscape performance should be integrated into the design and development process. LAF will continue to pursue similar collaboration opportunities through grants and fee-for-service partnerships.
LAF plans to stay involved with the 11th Street Bridge Park project as it moves through the design process and hopes to partner to evaluate the performance of the site and produce a Case Study Brief once the park is built and operating.
Landscape architecture is a practice of continual inquiry with investigation at its core. But how and why do we undertake research? How do we assess its legitimacy? Where does basic research fit in? And how might we better transform knowledge into practice?
On Friday, October 21 at the American Society of Landscape Architects (ASLA) Annual Meeting, LAF will participate in a panel to consider these questions. Eric Kramer of Reed Hilderbrand, Kate Orff of SCAPE Landscape Architecture, and Heather Whitlow of the Landscape Architecture Foundation will discuss these issues in an interactive panel session that aims to probe and envision the next frontiers of landscape architecture research.
To prepare for the session, we want to know how practitioners are using and engaging in research. If you are a landscape architecture practitioner, please take a few moments to complete this short 6-question survey:
Research and Practice: What Does It Mean? Why Do We Do It?
Fri, Oct 21, 10:30am-12:00pm
Ernest N. Morial Convention Center, Room 271
The Landscape Architecture Foundation (LAF) and its research initiatives will be well-represented at the upcoming Council of Educators in Landscape Architecture (CELA) Conference March 23-26 in Salt Lake City, Utah. Organized by Utah State University, the conference will also involve a day trip to the main campus in Logan, Utah.
LAF staff will present during two Concurrent Sessions, report to the CELA Board and Administrators during their respective meetings, and host a meet-and-greet for the 2016 CSI Research Fellows and past Landscape Performance Education Grant and Case Study Investigation (CSI) participants. The conference also features a number of presentations from LAF program participants, who will speak about their methods, findings, and further research.
In total, research from and about LAF’s various Landscape Performance Series initiatives will be part of seven sessions:

Evaluating Performance of Campus-based Agriculture: Is Bigger Better?
D. Scott Douglas, University of Illinois at Urbana-Champaign
From October 2014 through September 2015, the Landscape Architecture Foundation (LAF) partnered with the General Services Administration (GSA) to evaluate the performance of the U.S. Coast Guard Headquarters site on the St. Elizabeth’s West campus in southeast Washington, DC, the largest federal redevelopment project since the Pentagon. This acclaimed project earned LEED Gold certification and features an extensive stormwater management system.
GSA is charged with providing workplaces for the federal government by constructing, managing, and preserving government buildings and by leasing and managing commercial real estate. Because GSA has committed to incorporate sustainability principles — including sustainable site design and management — in all of its real estate transactions, the agency was interested in studying the U.S. Coast Guard Headquarters site to test assumptions, assess materials, and understand the built condition.
The collaboration followed the model of LAF’s award-winning Case Study Investigation (CSI) program, with an academic team (Professor Christopher D. Ellis, PhD and student research assistant C. Dylan Reilly of the University of Maryland) leading the research and members of the design team (Emily McCoy of Andropogon and Brandon Hartz of HOK) lending their insights. Because of the longer timeframe, the partnership provided the opportunity for a more expansive study than what is possible through the 6-month CSI program.
The year-long partnership allowed the 31-acre site to be studied through all four seasons in order to achieve a more balanced and nuanced picture of its performance. The research looked at a variety of ecosystem services provided by the site’s most notable features: 985 new trees, over 400,000 sf of green roofs, and a 2.4-acre stormwater pond. It also assessed workers’ use of and satisfaction with the outdoor open spaces, and use of alternate modes of transportation.
The researchers used temperature loggers to record and compare surface temperatures on areas of conventional black rubber roof, sedum green roof, and green roof planted with tall grass. They also compared native plant species and average site surface temperatures to those at a traditional office landscape. For the two courtyards, they used time-lapse photography to quantify the number of people using the space and determine the most common uses. They also observed commuter traffic to document the modes used and conducted a survey of employees to determine their satisfaction with the outdoor spaces.
The products of this collaboration are a Landscape Performance Series Case Study Brief and an internal report for GSA that discusses performance, provides recommendations for site management and maintenance, and suggests areas for further research.
LAF was proud to be part of this important study and will continue to pursue opportunities for longer-term research partnerships to evaluate the performance of exemplary built landscapes.
Tum Suppakittpaisarn, a Doctoral student at the University of Illinois at Urbana-Champaign, is conducting a visual preference survey of urban stormwater management strategies. He is working under the supervision of Dr. William Sullivan in the Department of Landscape Architecture.
Landscape Architecture professionals, professors, and students (18 or older) are invited to complete a short survey to rate images of landscapes from seven cities across the United States. The images depict different ways of dealing with flooding and rain water. The survey takes less than 10 minutes to complete.
