Just north of Beijing, between the Great Wall and Yanqi Lake, the Xingfa Cement Plant once fueled China’s construction boom, operating for over two decades before its 2015 closure under the National Air Quality Action Plan. Today, an adjacent quarry that once provided raw materials has been remediated as a 107.5-hectare terraced park that anchors an accompanying 17-acre research campus on the site of the plant.
Where a single willow tree once stood, the valley now supports a vast, layered network of emergent plant communities selected to adapt in rocky, alkaline soils. Native arborvitae stabilize slopes and retain moisture through summer droughts. Legume-producing species enrich the thin soil, while seasonal stands of smoke tree, mulberry, and elm provide canopy and seasonal color. Invasive plants introduced during the site’s industrial era have been cleared and replaced with species that restore soil conditions. On the southwestern end of the site, a seasonal pond has been added to retain stormwater runoff and reduce erosion across the exposed quarry floor.
Paving, walls, and trail edging were constructed using recycled stone and shale. Salvaged conveyor housings and other industrial remnants were embedded into the landscape along the “Trail of Memory,” a pedestrian spine linking the two quarry pits that pays homage to the site’s industrial past. Climbing up a nearby hilltop to an overlook pavilion, a 1.2-kilometer hiking trail provides panoramic views of the surrounding Yan Mountains.
Park 101
The ambitious Park 101 aims to cover part of downtown Los Angeles’ 101 Freeway with a multi-purpose park that will include playgrounds, seating, festival areas, and a plaza. The approximately four-block cap park will reconnect the two sections of Downtown that have long been separated by the freeway, greatly enhancing the currently noisy, with much-needed shad...
Gantry Plaza State Park
Once a working waterfront teeming with barges, tugboats, and rail cars, the Hunter’s Point shoreline slowly succumbed to the realities of the Post-Industrial Age and this spectacular site was left to deteriorate. Thomas Balsley Associates, together with Weintraub di Domenico, envisioned Gantry Plaza State Park as a place that celebrates its past, future, skyli...
Hunter's Point South Waterfront Park
Hunter’s Point South Waterfront Park was envisioned as an international model of urban ecology and a world laboratory for innovative sustainable thinking. The project is a collaboration between Thomas Balsley Associates and WEISS/MANFREDI for the open space and park design with ARUP as the prime consultant and infrastructure designer.

Great Park
One of the world’s largest municipal parks, the 1,300-acre Great Park in Irvine, California, is currently under construction with phased openings continuing through 2029. The conceptual framework encompasses redesign and implementation of near- and longer-term uses, with the intent to “put the park back into the park.” The vast site, which was once the Marine ...
