On August 12, 2018, I attended a meeting of a new committee created by the Environmental Water Research Institute (EWRI) of the American Society of Civil Engineers (ASCE). The task force, comprised of approximately 40 stormwater professionals, is titled: ASLA/EWRI Committee on Plants and Soils Performance in Green Stormwater Infrastructure (GSI). The committee will produce recommendations over the next few years that will be distributed in a booklet and online. This work will be specifically focused on providing better research-based guidelines for soil performance and plant performance as an overlapping, interrelated system rather than as individualized elements. The committee’s goal is to provide guidance on short-term, medium-, and long-term practices to ensure that systems maximize performance.
Additionally, other sub areas such as biodiversity, maintenance, and soil microbial functions will be considered. The landscape architects on the taskforce will take the lead in addressing aesthetics and other social parameters that can support or impede acceptance of Green Infrastructure as an important component of place making.
The first phase of the task force’s efforts is to create an annotated bibliography as an indicator of where research is headed and to reveal significant gaps that should be addressed. The literature review phase is being organized by Harris Trobman, Project Specialist in Green Infrastructure at the Center for Sustainable Development and Resilience, The University of District of Columbia. The committee needs good research-based literature, especially as it relates to the performance of plants in green infrastructure. If you have a favorite book or article that you would like to share, please send it to me by December 1, 2018, and I will format it for inclusion in the bibliography. Currently, the bibliography is reflective of the vast preponderance of research that has traditionally come from engineers and scientists. Please free to contact me with questions and/or comments as well. If you would like to format the citation yourself, I can send an example.
