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.
Freedom Park Master Plan
In the late 20th century, Atlanta faced a critical juncture as a proposed highway threatened to tear through seven urban communities. From this crisis emerged a powerful grassroots movement whose victory not only halted the highway but birthed Freedom Park, a 130-acre green space stretching over 2.5 miles.
For years, Freedom Park existed as a patchwork ...
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.

Perk Park
Originally completed in 1972, this vestige of IM Pei’s urban renewal plan was built when the street was seen as a menace and parks turned inward. Rolling berms surrounded the edges and the sunken middle areas were filled with concrete retaining walls. After years of decline, Thomas Balsley Associates’ designed a plan to reunite the community with its park. The...
Riverside Park South
Located on the West Side of Manhattan on the scenic Hudson River shoreline, Riverside Park South is a massive, multiphase project of sweeping ambition and historic scope. Combining new green space, new infrastructure, and the renovation of landmark industrial buildings, the plan – originally devised by Thomas Balsley Associates in 1991 – is an extension of Fre...
