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.
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...
Palisades Park
Santa Monica’s famous pier area draws visitors who often disregard pavement boundaries and compact the landscape soil. Palisades Park, adjacent to the iconic pier, is a particularly active site for cyclists and tourists that has long been in need of a planting strategy to discourage pedestrian overflow into the landscape. SWA’s defensive planting strategy tack...
Temple City Playgrounds
Ten miles east of Los Angeles at the base of the San Gabriel Mountains, Temple City sought to upgrade its aging parks and existing playgrounds into safe and welcoming spaces for community members of all ages. SWA worked with the city to host a community engagement workshop focused on renovating two city playgrounds: Live Oak Park, the city’s largest park, span...
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.
