Passaic River Flood Tunnel

The Passaic River Flood Tunnel is a proposal for a flood relief tunnel from the central portion of the Passaic River basin in Passaic County, New Jersey in an area where a number of large tributary rivers join the Passaic River and severe flooding occasionally occurs. The tunnel would provide relief to an area that experiences severe flooding events which cause tens of millions in property damage and disruption to lives.
