|The CEMVN, in cooperation with the NPS, proposes to partially restore the hydrologic connection between Bayou aux Carpes and Bayou Barataria (Gulf Intracoastal Waterway or GIWW). This work would involve removing earthen and shell material that was deposited to plug Bayou aux Carpes circa 1974 where these two waterways previously met. The BAC Site and relevant features are shown in Figure 1. The purpose of the Proposed Action would be to construct an augmentation feature(s) that would provide environmental benefits to the BAC Site’s ecologically significant wetlands to offset any unanticipated indirect impacts associated with the WBV 404(c) floodwall. A description of these wetlands and their significance is included in Section 4.2.3.
