San Francisco, California



For the past few years Groundworks Office has been working with a hardy group of neighbors and park stewards to turn this challenging remnant site into a new urban gathering node.  With commanding views to the south, the half-acre park is chock-full of site constraints and limitations; location atop a rail tunnel and its proximity to Interstate 280.  The response has been to keep the design simple and without any load bearing structures, and focused on mitigating both noise and expanding the ecological relevance of the site.  

The focal point of the new park is a flexible paved area that will provide a much-needed space for play in the neighborhood.  Site storm-water is being focused into a wetland garden that will host a number of aquatic plants and with any hope a frog.  A new site-planting regime will be installed that supports local native and drought tolerant plants.  A special focus has been placed on plants with a high ecological value that will foster and attract at risk species of both insects and small birds.
