Passaic River Basin Flood Protection Project, Storm Surge Analysis
Abstract
The US Army Corps of Engineers, New York District, Passaic River Division (PRD) has been working on plans to reduce flooding in the Passaic River Basin since 1939, but none of those plans was authorized. Congress then authorized the Corps to conduct a new study of the basin for the state of New Jersey in the Water Resources Development Act of 1976. The Corps evaluated more than 150 plans, presented an array of plans to the state of New Jersey, and the state selected a dual-inlet water diversion tunnel system as the centerpiece of its comprehensive flood protection program for the basin. In November 1990, Congress authorized construction of the $1.2 billion Passaic River Flood Protection in the Water Resources Development Act of 1990; the project cost to the state is $310 million. The major elements of the project are two underground tunnels, a 20.1-mile-long main tunnel about 40 ft in diameter and a 1.2-mile spur tunnel about 22 ft in diameter that convey central basin flood waters to an outlet in the vicinity of Kearny Point in Newark Bay. The proposed diversion tunnel and surface works are generally designed to protect against the 100-year flood event, during which it is anticipated that a flood volume equal to that of Newark Bay will be discharged over a two-day period.
