| wetlands subject to Section 404 (b) of the Clean Water Act of 1977, based on evidence gathered during field inspection of the aforementioned area (wetland site W-2). Based on the consideration discussed in the Final EIS, in compliance with the requirements of Executive Order 11990, it has been determined that there is no practicable alternative to the proposed construction in wetlands and that the proposed action includes all practicable measures to minimize harm to wetlands which may result from such use.
The runway extension would also encroach into a floodplain fringe area (but not the main floodway). Due to the small area affected, no appreciable increase in flood heights will occur.
COMMITMENT:
The La DOTD will minimize the area of wetlands to
be affected for the required Lafayette Regional
Airport runway extension, by utilizing design
features that avoid the need to relocate
Bayou Tortue. This will include embankment
stabilizatiton with riprap or other means.
MITIGATION:
Approximately five acres of wetlands would be adversely impacted by the project. Potential methods of mitigation for wetland impacts include restoration, creation, or mitigation banking that would provide off-site locations for this mitigation. During the Section 404 permitting process, LaDOTD will implement mitigation by one of the above methods, if determined appropriate.
STATUS:
