The city of San Francisco and private developers planned a $1.5 billion redevelopment of Yerba Buena Island (YBI) and its adjoining island, Treasure. This required infrastructure improvements, upgrades and slope failure repair to the road—work that was necessary after heavy precipitation in fall 2021. The heavily eroded slope had almost a sheer vertical dropoff, was 120 feet long and consisted of silty, sandy soil.
ENGEO, a geotechnical engineering firm, contacted Solmax for a solution designed to increase slope stability and erosion protection while also preserving underground utilities.
Installers used harnesses and ropes tethered at the crest for safety. After installation, the high-performance turf reinforcement mat was sprayed with a bonded fiber matrix containing native seed to establish vegetation. No additional construction equipment, road closures or traffic control were required.
The installation was so successful that the solution was installed at three additional YBI sites.
The project was recognized with an Award of Excellence in the Site Development category of the 2024 Advanced Textiles Association International Achievement Awards.
