Deepening Areas: ► Deepen from the Entrance Channel to approximately River Mile 13
from the existing 40-foot depth to 47 feet
Widening Areas:► Area 1: Mile Point: increase to the north by 200 feet
Training Wall Reach: increase to the south 100 feet transitioning to 250 feet
► Area 2: St. Johns Bluff Reach/White Shells Cut: up to 300 feet
Turning Basin Areas:► Blount Island: ~ 2700' long by 1500' wide

Estimated Project Cost: ~$684 million► Federal Share ~ $312.7 million
► Non-federal Share (JAXPORT) ~$371.5 million
► Benefit-to-Cost Ratio (BCR): 2.70
► Mitigation $2.9M
► Monitoring: Construction + 1 yr: $7.5M
► Monitoring/Corrective Action Plan:
Year 2-10: $23.3M (non-federal)
Estimated Construction Duration:
4 - 6 years
18 million cubic yards of material
expected to be dredged
Dredged material placed in an ocean site
(unless suitable for beach or other areas)
Principles and Guidelines:
“Contribute to national economic development
consistent with protecting the Nation’s environment”
“Each alternative plan is to be formulated in
consideration of: completeness, effectiveness,
efficiency, and acceptability. Appropriate mitigation
of adverse effects is to be an integral part of each alternative plan.”

DEEP DRAFT NAVIGATION ECONOMICS“HARBORSYM”
Corps “Enterprise” model for
coastal navigation projects
Inputs include:
► Port layout
► Vessel calls
► Transit rules/restrictions
Model calculates costs of delays and changes in vessel
transportation costs
Savings in transportation costs = NED benefits
NED Plan “reasonably maximizes” net benefits

PROJECT AND SEA-LEVEL CHANGE
Used current guidance (EC 1165-2-212)
Results of analysis for the 50-year
period, 2018-2068:
Low: 0.39 feet
Intermediate: 0.87 feet
High: 2.4 feet
Conclusion for navigation:
Based on these sea-level rise
projections and elevations of
current and planned port facilities,
no impacts on navigation and
minor impacts on port facilities
Conclusion for salinity impacts:
Majority of salinity changes will
occur due to sea-level change;
only minor impacts attributable
to the project
