Bay Remediation Site 1: Horseshoe Cove
San Francisco, CA
Interstice Architects, San Francisco
Project Principal: Zoee Astrakhan and Andrew Dunbar
Team Leader: Arjun Bhat
Project Designer: Jon Ganey
Client: California Architectural Foundation

View of Horseshoe Cove from Kayak Launch —The view shown of BRS 1: Horseshoe Cove is looking bay-ward toward the City of San Francisco, with Golden Gate Bridge pictured on the right.  Once constructed, this project will contribute to the production of a local and regional, healthy bay ecology, while simultaneously engaging its human community - a critical aspect of its success, becoming a visible and magnetic destination for tourists, naturalists, scientists, and recreationalists alike.

Site Section D—Shows the trajectory passing through the lupine meadow, a production and remediation field with observatory beyond, the tidal marsh and tidal generator wall, and a seeder buoy array.  The tidal generator wall is accessed by a boardwalk which also shares access to the research hut, an observatory for marine and tidal scientists to interface with the public.
Site Section C—Shows the trajectory passing through the lupine meadow, a wetland zone, a production and remediation field and a breakwater habitat island extending south into the water.  The intertidal plot field is accessed by a ramp from the catwalk so that production beds may be maintained, monitored by researchers as well visiting educational groups.
Site Components Diagram—This diagram illustrates the basic components that together comprise the site access, environmental and energy generation infrastructure for any given Bay Remediation Site. Prefabricated auxiliary program infrastructure can be deployed on a site-by-site basis to accommodate the specific research, event and social program opportunities for each site.
Species Timeline—The timeline illustrates the increased bio-diversity that is anticipated within and directly adjacent to BSR 1 as the project develops over time. The adjacencies and inter-connections are instrumental in the success of the entire 6.3 acres as an ecologically productive network comprised of both plants and animals.

Local to Regional Remediation—The eelgrass productivity cycle is illustrated here, as a foundational bio-remediation process at BRS 1, among other strategies that will be implemented.  The eelgrass is selected both locally for habitat establishment and in terms of its ease of transport to future sites.
Regional Remediation Strategy—The BRS 1: Horseshoe Cove Bio-Farm is constructed and managed as a nursery to export eelgrass seedlings to other remediation sites throughout the Bay.   As new BRS site are grown, the on-going production of eelgrass seedlings are transferred by buoy to sites in need
Site Plan—The Site Plan illustrates the ecologically-based and agriculturally-informed infrastructures constructed throughout the site, situated to support habitat and species diversity.  Examples of the constructed features include, planted meadow and forest, “farming” of eelgrass and oysters, power generation and resource distribution features, and walkways and platforms for scientific and recreational engagement by the public.
Site Concept / Strategic and Component Diagrams—Strategic Formal Concepts:
The first Strategy is Rethinking the Seawall – turning a boundary of resistance into a boundary of exchange and thereby creating edge porosity and biological potential.The second Strategy is site-wide Cut and Fill Balance, providing an extended literal zone through a simple topographical change and opportunities to create wave breaks and habitat islands that are crucial to tidal marsh environments.
Site Potentials—The 6.3 acre historic site for Bay Remediation Site 1 (BRS 1) is situated just north of the Golden Gate Bridge on the San Francisco Bay.  The project proposes taking advantage of the site’s inherent potentials and adjacencies: adjacency to the Bay and the Bay Area Discovery Museum, location at the outlet of the local watershed for Fort Baker as part of the GG National Recreation Area, adjacent to the Coast-guard station and nearby NOAA research facilities in Tiburon, adjacent to the Travis marina and Presidio Yacht Club and other recreational maritime activities in the direct vicinity.

BRS 1 is a 6.3 acre bio-remediation nursery and ecological educational center located in Horseshoe Cove on the San Francisco Bay.  It is a new bayside typology, a highly visible and evolving landscape infrastructure that addresses the loss of estuarine flora, fauna and habitat by taking advantage of rising sea levels which threaten our future.  The former seawall is demolished, creating an intertidal boundary of exchange, thereby revitalizing this brackish nutrient rich cove.  Eco-structures—appropriated agricultural models of industrial food production—are deployed on a large scale and include: a nursery of biological crops, a filigree of modular catwalks anchored to wind and tidal-power piers, a field of pre-seeded remediation plots, integrated oyster farm fences, seeding buoy arrays, and fixed and dynamic structures to view, maintain and learn from the remediation.  The biological products of this agriculture-based operation supply animal and plant ‘seed’ material for subsequent Bay remediation sites.
