Why Mesothelioma Cases Occur in Redwood City
Redwood City's asbestos legacy is rooted in its waterfront industry. The Port of Redwood City, the only deep-water port on the San Francisco Bay south of San Francisco, handled bulk cargo including sand, gravel, cement, and industrial materials for decades. Dockworkers, longshoremen, and marine terminal workers were exposed to asbestos in ship insulation, cargo handling equipment, and port infrastructure.
The Pacific Shores industrial area along the bayfront was home to multiple manufacturing and processing operations. CEMEX (formerly RMC Pacific Materials) operated a cement plant where asbestos was used in kiln insulation, pipe lagging, and building materials. The Leslie Salt Company operated salt evaporation ponds and processing facilities where asbestos-containing materials were used in industrial equipment.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Redwood City facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Redwood City continues to produce new mesothelioma cases decades after asbestos use was restricted.
Redwood City's shipyard operations along the waterfront added to the asbestos exposure burden. During World War II and the postwar era, ship repair and marine construction activities used asbestos insulation extensively in ship interiors, engine rooms, and marine equipment.
The city's downtown commercial district and residential neighborhoods, largely built between the 1920s and 1970s, incorporated asbestos-containing materials in their construction. Schools, county government buildings (Redwood City is the San Mateo County seat), and commercial structures all used asbestos products.
Redwood City's Asbestos Legacy by the Numbers
The Port of Redwood City has operated since 1937. CEMEX's cement operations handled millions of tons of material. Redwood City is the county seat of San Mateo County. California allows only 2 years from diagnosis to file a mesothelioma claim. Documenting your asbestos exposure history is a critical first step.
