The 2016 completion of the Panama Canal expansion allowed larger ships to transit directly between Asia and the U.S. east coast. This provided a unique high-economic-value opportunity for the Port of Jacksonville to become one of the few ports on the U.S. east coast capable of serving the larger ships traversing the canal. Monetizing this opportunity requires expansion of the federally authorized Jacksonville Harbor Navigation Project. To that end, the U.S. Army Corps of Engineers (USACE) Jacksonville District worked with the local sponsor—the Jacksonville Port Authority—to develop and implement the National Economic Development alternative, the channel redesign which produces the highest net benefit to the nation. During its studies, USACE enlisted Taylor Engineering multiple times as the project evolved from general reconnaissance and planning phase in 2009 to the complex plan formulation process—documented in a General Reevaluation Report (GRR) and an Environmental Impact Statement (EIS)—completed in 2014. The plans investigated depth alternatives from 40 to 50 feet from the river mouth upstream a distance of 20 miles. Taylor Engineering met the accelerated schedule (14 months ahead of schedule), the Chief of Engineers signed the Jacksonville Harbor Deepening Project report, and the U.S. Congress authorized the project as part of the Water Resources Development Act of 2014. We subsequently assisted the USACE with expert witness services defending a challenge to the USACE’s state-issued environmental permit.
