Coastal Storm Risk Management:
A Regional Approach
•Construction of a region-wide risk reduction system,
along with ecosystem restoration, will improve our
ability to respond to future storms and address long-
term impacts of sea level rise & land subsidence.
•The Port Arthur Project is a component of the Sabine
Pass to Galveston Bay Program (S2G) which includes
project areas in the cities of Port Arthur (Jefferson),
Freeport (Brazoria), and Orange (Orange).
•The objectives of the overall S2G Program include:
•Reducing risks to human life from storm surge;
•Reducing economic damages to residents,
businesses, and infrastructure;
•Enhancing energy security by reducing storm
surge risk to petrochemical facilities; and
•Reducing adverse physical impacts to waterways
used for commercial and recreational activities.
Texas Coast Regional Approach
Port Arthur Project Executive Overview
The Port Arthur Project, one of three S2G projects, is located in
Southeast Texas, approximately 12 miles from the Gulf of Mexico, on
the west side of Sabine Lake. The Project will provide improvements
to the existing Hurricane Flood Protection Project (HFPP) system and
provide protection for the 1% Annual Exceedance Probability (AEP)
100-Year Storm Event combined with 2077 Relative Seal Level Rise
conditions.
The improved Coastal Storm Risk Management (CSRM) system will
increase the level of performance and resiliency of the HFPP.

Port Arthur Project Overview
Port Arthur Project (1% AEP and 2077 Relative Sea Level Rise)
Construct 21 new road/railway closure structures
Eliminate 1 road closure structure (FM-365) / Fill-in with earthen levee
Install erosion protection (stone-armoring) at multiple locations
Construct concrete fronting protection along the CSRM levee system
at 10 existing pumping stations
Port Arthur Project (1% AEP and 2077 Relative Sea Level Rise)
Raise approximately 10.95 miles of existing earthen levees
Construct or reconstruct approximately 5 miles of new concrete floodwalls
Construct approximately 4.1 miles of new earthen levee at multiple locations
(Western Alignment –Atlantic Road –Port Neches Extension)
o USACE is partnering with Jefferson
County Drainage District # 7 (DD7),
the Non-Federal Sponsor), to design
and construct the Port Arthur Project.
o The Federal Government is
responsible for 65% of the cost and
the Non-Federal sponsor is
responsible for 35% of the cost.
o Currently working on obtaining federal
approval for the cost increase by the
end of 2025.
o Cost increases driven by a variety of
factors including: increased scope due
to updated storm modeling, labor and
construction cost increases, inflation,
and revised utility relocation costs.
