Help Us Create the Next Generation LPS

The Landscape Architecture Foundation (LAF) is currently developing a new website to house its Landscape Performance Series and related resources. The goal of the redesign is to enhance the user experience with improved organization, new resources, and more ways to browse and search the content.

startrek-lps-300wTo help us create the most dynamic website possible, we are seeking input from a variety of LPS users, from the one-timers to the diehards. We’ve developed the following short surveys for different user groups.The surveys focus on your use of the LPS, what you find most useful, and what additional functionality and resources you would like to see. Please take a moment to complete the appropriate survey and tell us what you think!

As a thanks for completing the survey, your name will be entered into a drawing to win LAF’s award-winning book, “Greening Cities, Growing Communities: Learning from Seattle’s Urban Community Gardens.”

LAF is also conducting phone interviews and focus groups for those wishing to provide more detailed feedback or engage in an open conversation about the website. If you are interested, please contact us at:

Thank you in advance for your time, input, and assistance in making the Landscape Performance Series the best resource it can be!

Coming Soon: 20 New LPS Case Study Briefs

Now through November, LAF is rolling out 20 new case studies that showcase the environmental, economic, and social benefits of high-performing landscapes. Visit the LPS Case Study Briefs page to see the latest or follow us on Facebook , LinkedIn , or Twitter to get updates as each new case study is released.

The case studies are part of LAF’s award-winning Landscape Performance Series, an online, interactive set of resources to help you quantify benefits, show value, and make the case for sustainable landscape solutions. By year-end, the searchable database will contain over 80 Case Study Briefs.

From Dallas’ Klyde Warren Park to private residences in Aspen to the 1,000-acre Napa River Flood Protection Project, the new case studies represent a range of geographic locations, scales, project types. Documented landscape performance benefits include:

  • newlpscasestudiesFilters 4.5 million gallons annually, 100% of surface runoff from 12.5 acres of developable properties adjacent to the park. (Milliken State Park, Detroit, MI)
  • Improves the quality of life for 99% of 108 park users surveyed. (Buffalo Bayou Promenade, Houston, TX)
  • Creates an estimated 1,373 construction jobs and 1,254 permanent jobs on properties developed as a result of flood protection. (Napa River Flood Protection Project, Napa, CA)
  • Provided a hands-on educational experience for 450,000 people. (Chicago Museum of Science and Industry Smart Home, Chicago, IL)
  • Increased calmness in 57% and made the hospital stay easier for 50% of patients surveyed. (Advocate Lutheran General Hospital, Park Ridge, IL)

These exemplary projects were documented through LAF’s 2013 Case Study Investigation (CSI) program, a unique research collaboration that matched eight LAF-funded faculty/student research teams with practitioners from 20 participating design firms. The teams worked together to develop methods to quantify performance benefits and produce the Case Study Briefs.

Through the Landscape Performance Series and Case Study Investigation programs, LAF is working to advance our collective knowledge of landscape performance and lead the profession to routinely design with specific performance objectives, collect performance data, and integrate landscape performance in design education. The next CSI program will run March – August 2014 with applications available starting in October.

Top 7 Back-to-School Case Studies

It’s hard to believe that summer is winding down, and that in some places classes have already begun. To celebrate the upcoming schoolyear, we’ve compiled a collection of LPS Case Study Briefs on school and campus projects that showcase the environmental, economic, and social value of sustainable landscapes. Here they are, each with one key landscape performance benefit highlighted…


The Willow School - Gladstone, NJ

Engages all 250 students in an educational curriculum that includes landscape processes and ethics. When a sample of students were asked to list environmentally-friendly features of green buildings, 82% listed landscape features such as rainwater harvesting, composting, vegetable gardens, or wetlands.


Brent Elementary Schoolyard Greening - Washington, DC

Introduced 1-2 hours per week of outdoor classroom experience for grades 1-5, and 4-5 hours per week for preschool and kindergarten. Sixteen classes use the “Nature Classroom” for subjects ranging from science to art, music, and English.


TJU Lubert Plaza - Philadelphia, PA

Increases satisfaction with TJU as a workplace/university, with 81.2% of respondents saying that the presence of the plaza probably or definitely increased their satisfaction and 88% reporting to feel more positive after spending time in the plaza.


The Dell at the University of Virginia- Charlottesville, VA

Reduces sediment and nutrient loadings downstream, reducing total suspended solids by 30-92%, phosphate by 23-100%, and nitrate by -50-89% according to water sample data.


Yale University’s Kroon Hall - New Haven, CT

Saves 634,000 gallons of potable water each year by eliminating the need to use potable water for irrigation and, in concert with water-conserving plumbing fixtures, reducing the building’s potable water use by 81%.


University of AZ Sonoran Landscape Laboratory - Tucson, AZ

Reduced potable water use for irrigation during the desert establishment period (first 3-5 years) by 83%, or 280,000 gallons annually. After the establishment period, the need for potable water in irrigation should be eliminated.


Gary Comer Youth Center - Chicago, IL

  • Produces 1,000 lbs of fruits and vegetables annually. Food from the rooftop feeds 175 children at the center each day, is distributed among four local restaurants, and is sold at a local farmers market.

In Sept/Oct, look for 20+ new Case Study Briefs as we publish the products of the 2013 Case Study Investigation (CSI) program.

LPS on the Road: EDRA and Upstate New York

Over the past month, LAF has presented the Landscape Performance Series to landscape architects, design researchers and other built environment professionals across the northeast, including conference visits in Providence and Rochester.

edra44In Providence, LAF participated in the Environmental Design Research Association (EDRA) 44th Annual Conference, presenting on the Case Study Investigation (CSI) program as part of a panel with researchers from the University of Maryland and firm liaisons from EDSA, Reed Hilderbrand, and Sasaki. The presentation focused on the experience of these CSI participants, who worked together during the summer of 2012 to study and document the performance of three diverse projects:

The panel discussed opportunities and challenges in evaluating landscape performance. The designers from each firm spoke about their approach to researching their project’s performance, their reaction to receiving the performance data, and how their work has changed since.

Eric Kramer, of Reed Hilderbrand, explained that prior to CSI, “we talked about how projects performed, but we didn’t use those words… The value of CSI, was in part, to give us the language with which to have these conversations.” Of particular interest to Kramer were the CSI research team’s findings on Central Wharf Plaza’s effect on traffic safety: The number of accidents decreased from six in the years prior to the project, to just one in the years after completion.

Derek Gagne, of EDSA, explained how the experience of trying to gather performance data for Castiglion de Bosco led his team to incorporate performance metrics into projects from day one. The panel also discussed the larger issue of translational research as it relates to landscape architecture.

The next week in Rochester, LAF led a half day workshop for the New York Upstate ASLA Chapter’s “No Excuses” conference. The conference focused on green infrastructure, with presentations from LAF and experts from design firms, engineering firms, and industry. NYU ASLA President-Elect Joy Kuebler explained that “our goal for this event was to provide every opportunity to equip as many landscape architects with the basic knowledge and confidence needed to become green infrastructure community leaders at a price point that was affordable – hence the name ‘No Excuses’.”

LAF’s workshop introduced participants to the concept of landscape performance, the resources in the Landscape Performance Series, and the process of evaluating performance to show impact. Each participant brought in a project and used the full-morning session to analyze it and develop a research plan to document its performance.

As Kuebler summarized, the intensive workshop covered “how to use this incredible online resource to not only inform design, but to showcase the work that high performance landscapes do.” The workshop enabled “the group to critically examine their own projects and review their environmental, economic and social performance… This was an amazing opportunity to see how the documentation of our work contributes to the body of knowledge that defends the role of landscape architecture in the built environment.”

If you are interested in engaging your colleagues in dialogue on landscape performance, LAF would be happy to visit or schedule a webinar with your firm, organization, or university. For more information, contact us at

LPS Case Studies: A Preliminary Analysis

As LAF gears up to begin analyzing the collection of 50+ Landscape Performance Series (LPS) Case Study Briefs per the $22,500 cooperative agreement with researchers at Utah State, Temple, and Kansas State University, we did a few quick in-house analyses and thought we’d share the results.

The word cloud below shows the performance benefits represented in the first 50 Case Study Briefs, weighted by frequency. Stormwater management, water conservation, social & recreational value, and educational value are the most commonly quantified benefits. The least common are scenic quality/views, habitat preservation, and air quality benefits. To some extent, the benefits depend on the type of project — for example, a schoolyard would be expected to provide educational value, whereas a private residence likely would not — but more often the benefits simply reflect what data and information is available for each project.


Participants in LAF’s Case Study Investigtion (CSI) program, which has produced two-thirds of the LPS Case Study Briefs, are charged with conducting field observations, scouring achives and public datasets, and interviewing clients and users to evaluate the performance of projects. Through their expertise and ingenuity, they have found or developed dozens, if not hundreds, of methods for determining performance benefits. Some of the most commonly-used ones described in the case study Methodology documents seem to be:

We’re excited to work with the USU/Temple/KSU researchers to conduct a deeper examination of the metrics and methods in the collection of Case Study Briefs to gain insights and develop guidance that will make the evaluation of landscape performance more accessible to all.
