We don’t often work on two projects for the same location at one time or get interrupted by a hurricane, but with the Nord du Lac and River Chase projects in St. Tammany Parish, that’s exactly what happened.
Sain Associates began work on the site in 2003 by preparing a Traffic Impact Analysis for a movie theater and hotel on the site.
As time went on, it became apparent that the site would become much larger than initially imagined, and we started working with other consultants and agencies to develop what was once an old rest area into a functioning interchange to service large retail tracts on both the north and south sides of Interstate 12. On the north side of Interstate 12, plans moved forward to develop over 1 million square feet of retail that would become Nord du Lac. On the south side of Interstate 12, River Chase began developing plans for a mixed-use site. With so many players designing various parts of the site, there was a tremendous need for good coordination.
While the Nord du Lac site was attempting to gain approval from St. Tammany Parish, Hurricane Katrina blew through and stalled progress. After the storm, all studies had to be updated in order to gain approval.
Sain Associates performed the traffic impact studies for both Nord du Lac and River Chase. Services included the roadway design for Pinnacle Parkway and the roadway on the Nord du Lac site that connects LA Highway 21 to the new Tchefuncte River Interchange.
Sain worked with site designers on both projects to review internal traffic circulation. We also performed traffic signal designs and timing for the Tchefuncte River Interchange exit ramps, as well as several signals along Pinnacle Parkway, Brewster Road and LA Highway 21.
