When PPN members were asked to name technically innovative projects, we received many unique ideas and suggestions, with projects from across the country and around the world. The following were the only ones mentioned more than once:
- Central Park, New York City
- The High Line, New York City
- Jefferson National Expansion Memorial and the Gateway Arch, St. Louis
- Millennium Park, Chicago
- National 9/11 Memorial, New York City
- Teardrop Park, New York City

Chicago City Hall’s green roof, installed in 2000, has become a symbol of a commitment to sustainability. The building is shared with the county, where no green roof exists, providing a research laboratory for measuring impacts on temperature and air quality.

At the start of 2013, a questionnaire was sent out to members of ASLA’s Professional Practice Networks (PPNs). The theme: favorite spaces. As you can imagine, responses were varied, and included many insightful comments and suggestions. Synopses of the survey results were originally shared in LAND over the course of 2013, and we are now re-posting this information here on The Field. For the latest updates on the results of the annual PPN Survey, see LAND’s PPN News section.
