The Solution

HIGH-PERFORMANCE BUILDINGS & PLACEMAKING

Designed by landscape architect James Corner Field Operations—best known for New York’s famous High Line—and EHDD, the project includes a seismic upgrade to a historic building, the creation of two new learning labs, and a public Field Station in addition to the landscape work.​ All buildings are targeting LEED Gold certification, with a focus on reduced water and energy usage. The project is centered on creating inclusive gathering and learning spaces for visitors, with new picnic areas and play structures designed to evoke the Presidio’s natural history, as well as trails and overlooks to connect visitors with the landscape, the park’s cultural history, and beauty of the waterfront neighborhood. Incorporating this goal throughout all aspects of the project, the team repurposed old and declined cypress trees from the Presidio to create natural site furniture, driving further connection to nature and play.

REGENERATIVE LANDSCAPING

In addition to LEED certification for the buildings, the landscaped site area is targeting Bay Area-focused ReScape certification, which recognizes excellence in regenerative landscape design, construction, and maintenance practices. Half of the plants selected—180 species in total—are native to the Presidio and the new gardens are planted with world class soil that was extensively tested against high standards and incorporates compost to naturally restore and replenish the soil. Compiled of nearly 200,000 native and ornamental drought-tolerant plants, the landscaping reduces outdoor water use by 61%. Stok is managing the ReScape certification process to ensure the site is recognized for its regenerative landscaping and best practices are shared.
