California's Delta Tunnel Project Cost Surges to $20 Billion

New analysis reveals significant cost increase, sparking debate over environmental and economic impacts.

The Delta tunnel project's estimated cost has risen by $4 billion since 2020, now totaling $20.1 billion.
State officials argue the tunnel is essential for securing water supplies against climate change and infrastructure risks.
Opponents, including environmental groups and local communities, claim the project threatens ecosystems and local economies.
The state’s analysis suggests the tunnel would generate $2.20 in benefits for every dollar spent, despite the high costs.
Lawsuits and formal protests have been filed to block the project, citing potential harm to fish populations and tribal cultural resources.
