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 make improvements to an existing Hurricane Flood Protection Project (HFPP) system based on the 1% Annual Exceedance Probability (AEP) Storm Event combined with 2070 Relative Seal Level Rise conditions. The improved Coastal Storm Risk Management (CSRM) system will increase the level of performance and resiliency of the HFPP. Authority: Section 1401 (3)3, Water Resources Development Act of 2018 (P.L. 115-270) Project Sponsor: Jefferson Co. Drainage District #7 (DD7) Port Arthur Project Overview Port Arthur Project (1% AEP and 2070 Relative Sea Level Rise) Construct 21 new road/railway closure structures Install erosion protection (stone-armoring) at multiple locations Construct concrete fronting protection at 11 existing pumping stations along the CSRM levee system Port Arthur Project (1% AEP and 2070 Relative Sea Level Rise) Raise approximately 10.95 miles of existing earthen levees (ranging from 14.5 ft to 20.5 ft) NAVD88 in elevation Construct or reconstruct approximately 5 miles of new concrete floodwalls (ranging from 17.5 ft to 24.5 ft) NAVD88 in elevation Construct approximately 4.1 miles of new earthen levee at multiple locations (ranging in height from 1 to 14 ft) Project Funding o USACE is partnering with Jefferson County Drainage District # 7, the Non-Federal Sponsor, to design and construct the Port Arthur Project. o Civil works projects like this are cost-shared between the Federal Government and the Non-Federal sponsor. The Federal Government is responsible for 65% of the cost and the Non-Federal sponsor is responsible for 35% of the cost. o Total Project funding equals $863M 35%65% USACEDD7 Project Features o Construct or reconstruct 5 Miles of New Concrete Floodwall (Ranging from 17.5 ft to 24.5 ft in height) o Replace existing I-Walls with T-Walls o Provide Levee Erosion Protection (Stone Armoring) Raise Earthen Levees o Raise approximately 10.95 Miles of existing earthen levee (Ranging from 14.5 ft to 20.5 ft in height) o Provide Levee Erosion Protection (Stone Armoring) I-Wall T-Wall Project Features Twenty-One road & railroad closure structures will be constructed or replaced on public and private roadways.
