Environmental Re-evaluation

The DOTD 2003 ROD Selected Alternative approved by the Federal Highway Administration (FHWA) in the 2003 ROD is Alternative RR-4 Elevated in conjunction with the MPO Subalternative and Subalternative H. The 2003 ROD Selected Alternative uses parts of the existing Evangeline Thruway alignment as well as a new alignment adjacent to the railroad right-of-way.

Following the Public Hearing for the Draft Environmental Impact Statement (DEIS), the LCG adopted the RR-4 Elevated alignment as the locally preferred alternative with the request that two local collector streets remain open under the freeway. This request, identified as the MPO Subalternative was included in the 2003 ROD Selected Alternative. Subalternative H applies to the area north of Willow Street. It provides U-turns both north and south of the Martin Luther King Jr. Drive/Castille Avenue intersection and another U-turn farther north nearer the I-10 interchange.

The 2003 ROD Selected Alternative represents a balance of impacts in which certain factors were weighed in reaching a decision.

The 21 Commitments in the 2003 ROD to provide measures to avoid, minimize or mitigate potential adverse impacts are as follows:

1. Displacements
2. Standing Structures and Archaeological Investigations
3. Sterling Grove Historic District
4. Other Historic Properties
   (Eligible for Listing on the National Register of Historic Places)
5. Noise
6. Air Quality
7. Waste Sites
8. Water Quality
9. Chicot Aquifer
10. Lafayette Regional Airport Runway/Taxiway Displacement
11. Wetlands
12. Vermilion River
13. Parks
    (Section 4(f) and 6(f) Properties)
14. Live Oak Trees
15. Construction Debris
16. Destination Signing and Traffic Control Plans
17. Local Access and Circulation
18. Community Impacts and Cohesion
19. Corridor Preservation
20. Facility Construction
21. Joint Use Development Plan

A Section 106 Study was conducted during the Environmental Impact Statement in compliance with the National Historic Preservation Act. It was determined that unavoidable visual impacts would occur at the Sterling Grove Historic District, which is listed on the National Register of Historic Places (NRHP). A MOA was signed by FHWA, DOTD, State Historic Preservation Officer (SHPO), and the Advisory Council on Historic Preservation, with three MPO committees and the Lafayette MPO as concurring parties, that requires actions to minimize or mitigate impacts to the Sterling Grove Historic District and potential effects to archaeologically significant properties. Two other properties adjacent to the project, Wallis Estate and Trappey’s Plant Complex, were determined to be eligible for the NRHP; however, the project will not be an adverse visual effect. Another eight properties in the study area were determined eligible for the NRHP, but the Selected Alternative does not affect these properties. Mitigation in regard to Sterling Grove will be considered through the CSS process and defined in the Sterling Grove Mitigation Plan.

For additional historic properties identified during this Functional Plan phase, FHWA and DOTD will consult with the SHPO and other Consulting Parties.

• Prepare a mitigation plan for Sterling Grove Historic District
• Consideration of the following in the plan: landscaping, earthberms, masonry walls, special lighting, long span bridges, attention to use of under bridge areas, hardscape and brick paver treatment, fencing and parks
• Consideration of downlighting as appropriate on all lighting installations
• Provide the following to St. Genevieve Church and School:
  • Lighting in front and along adjacent streets for aesthetic and security purposes
  • Develop an illuminated and landscaped plaza in front of church
  • A decorative fence enclosing the area
• St. Genevieve will accept ownership and maintenance responsibilities upon completion of No. 4
• Greig Street will be redeveloped in a manner that enhances the St. Genevieve properties
• Assure that construction methods will minimize vibration damage to the church
• Seek input from St. Genevieve Catholic Church and School and the general public and the local government before submitting to the SHPO for approval
• Receive approval of the Mitigation Plan from the SHPO prior to preparing final plans for I-49 in the vicinity of the Sterling Grove Historic District
• If additional historic properties are identified following completion of the Mitigation Plan, the owners of the additional historic properties will be made aware of the Mitigation Plan and their input will be considered for amendments to the terms of the MOA.
