Section 106 process requires Federal, Federally assisted, and Federally licensed undertakings to take into account the proposed effects of the undertaking (as referred to in 36 CFR 800.9), including noise and visual impacts, on properties listed on or eligible for inclusion on the
National Register of Historic Places (NRHP), it was necessary to identify the area of potential effect for the 1-49 Connector. Through consultation with the State Historic Preservation Officer (SHPO) and LaDOTD it was determined that the area of potential effect would include all that area within 1/4 mile (0.4 kilometer) of the outer limits of all alignments-resulting in a standing structure survey corridor measuring approximately 314-mile (1.2-kilometer) wide. However, as the area between the Union Pacific Railroad and the I-10/I-49 interchange was developed after World War II, that area was excepted from the standing structure survey by the SHPO (Appendix A).
After the long delay since the July 2000 publication, are parts of the exempted area still ineligible? What property has been added to the NRHP database since this report studied the area?
