Professional Practice Networks
Sustainable Design and Development



The main objective of the ASLA PPN on Sustainable Design and Development is to collect, advance, and disseminate information on sustainable design practice and theory within the field of landscape architecture and affiliated fields. In this realm, we seek to establish and maintain alliances with ASLA National, USGBC, AIA, ULI, APA, and other organizations with similar focus.

We plan to research and make available references and documents related to our cause and strive to have a strong presence at both the local and national levels through our web page, The Field, conferences, and publications. Eventually, we anticipate gaining international alliances and affiliations to strengthen the influence of sustainable design.

The ASLA Sustainable Design and Development PPN’s secondary role, but initial impetus, has been to provide the motivation, drive, and framework for the development and implementation of a site-based rating system. The sustainable site rating system to be produced through the Sustainable Sites Initiative continues through a large, multi-organizational effort led by ASLA, the Lady Bird Johnson Wildflower Center, and the US Botanic Garden. This rating system is particularly targeted toward the designer or developer of a landscape site, park, infrastructure, or other non-building project. As a PPN, we continue to support the Initiative through local and professional outreach and speaking engagements.

We invite you to join the Sustainable Design and Development PPN. Your membership dues help us pursue our goals and disseminate information in a timely and efficient manner. You membership also gives you access to an online network with a discussion forum, and updates on the development of the Sustainable Sites Initiative. Members will be asked to comment and report on findings and product drafts.
