A low carbon concrete case study for a historic single-family home renovation in San Francisco's Presidio Heights — a William Wurster-designed ranch home requiring approximately 500 cubic yards of concrete for foundation, retaining walls, and metal deck applications. All final submittals came in below the cement thresholds set by the Bay Area low carbon concrete working group. Keys to success included early discussions with the homeowner, identifying applications that tolerate longer curing times, and team agreement on carbon reduction goals.
