Public City’s 3D-Printed Models Illuminate What Drawings Can’t

It’s a very complicated project, but because of the way we’ve been able to explore it and show people exactly what we mean, I think we’ve been able to take the conversation a lot farther a lot more quickly than we would have been able to in traditional drawings.”

The Winnipeg, Canada-based firm Public City has its office’s 3D printers humming for all its projects, says Liz Wreford, the firm’s cofounder and principal landscape architect. For Thunderhead, the winning competition design for the 2SLGBTQI+ National Monument in Ottawa, the concept was rooted in the prairie landscape and the experience of both dread and celebration that a thunderhead brings.

In 2016, Karen DeSalvo, the acting assistant secretary for health at the U.S. Department of Health and Human Services, noted that public health was in a new era where “one’s zip code is a better indicator of health than genetic code.” DeSalvo’s link between health and place underscored a pervasive and uncomfortable fact about living in the United States today: Racial and class-based segregation is both common and harmful for people’s physical and mental health.

When Joseph Yamada and his wife, Elizabeth, died within nine days of each other in May 2020, obituaries and appreciations appeared in the Los Angeles Times, the San Diego Union-Tribune, and NPR. Most focused on the couple’s incredible story: Born two days apart in 1930, the two met at age 11 at a Japanese internment camp.

They later attended the same high school, studied together at the University of California, Berkeley, then moved back to San Diego, where Joe Yamada became one of the most celebrated landscape architects of his generation and Liz Yamada was the first Asian faculty member at San Diego High School, later joining her husband’s firm, Wimmer Yamada & Associates, as a partner.

After Native Americans occupied Fort Lawton—today part of Seattle’s Discovery Park—in a peaceful protest in the early 1970s, the city negotiated a long-term leaseback of 20 acres of the 534-acre site with the United Indians of All Tribes Foundation. “The land was supposed to be given back to the local tribe from which it was taken, but that didn’t really happen,” says Meghan Jernigan, a traditional medicine program director with United Indians, which led the protest. “There wasn’t a lot of political support, but a growing, cross-cultural coalition made this space thrive and allowed for development of the Daybreak Star Cultural Center.” Continue reading A Star on the Horizon

Featured Story: “Bet the House,” by Zach Mortice. New York City’s public housing was once a visionary project that combined architecture and landscape in humane and practical ways, but years of systemic disinvestment scuttled that dream. A new landscape master plan for the New York City Housing Authority by Grain Collective and Nancy Owens Studio looks to kick-start a transformation long overdue.

The territory was still recovering when Hurricane Fiona struck in September 2022, bringing up to 30 inches of rain in some areas, killing 25 people, knocking out power to the entire island, and causing some $10 billion in additional damage.
