National Infrastructure Simulation and Analysis Center Risk Development and Modeling Branch Homeland Infrastructure Threat and Risk Analysis Center Office of Infrastructure Protection In Collaboration with The National Incident Management Systems and Advanced Technologies Institute at The University of Louisiana at Lafayette Louisiana Highway 1/Port Fourchon Study July 15, 2011 i This page intentionally left blank. ii Executive Summary Port Fourchon is located at the southern tip of Lafourche Parish, Louisiana, along the coast of the Gulf of Mexico. The port is the southernmost port in Louisiana and centrally located in a large area of the Gulf that is rich in oil and natural gas drilling fields. Shallow water operations are serviced out of many ports along the Gulf Coast, but servicing for deepwater operations is located at select ports due to the use of larger vessels that are required to support deepwater operations. Due to its central location, deep channels, favorable weather conditions, and size, the oil and gas industry has chosen to concentrate its infrastructure for deepwater oil and gas operations support at Port Fourchon. Roughly 270 large supply vessels traverse the channels of Port Fourchon each day. Normally, about 75 percent of these vessels are servicing drilling rigs. Even though there are many more production platforms that require servicing than there are operating drilling rigs, drilling operations require much more material than production requires. The supplies and materials sent to rigs and platforms from Port Fourchon are brought into the port by the 600 eighteen-wheel trucks that travel on Louisiana Highway 1 (LA-1) each day.

In addition, according to the FEMA Preliminary DFIRM map provided on the LSU AgCenter website (http://maps.lsuagcenter.com), the site is located in Flood Zone “A”. A determination was requested from the Flood Plain Administrator, who determined a BFE of elevation 32 feet (determination attached).The LiDAR contours downloaded from LSU’s ATLAS site indicate that the site ranges in elevation from 23 feet to 59 feet at the top of the levee, and the mean elevation of the developable property on the site is at elevation 32 feet. The site currently has approximately 197 acres of contiguous property fronting Highway 981 that is above the base flood elevation of 32 feet. Therefore, no further action is needed to meet floodplain construction standards. Thank you for the opportunity to assist you in this project.
