The purpose of the proposed Mid-Breton Sediment Diversion is to reconnect and re-establish the deltaic sediment deposition process between the Mississippi River and the Breton Sound Basin through a large-scale sediment diversion that is consistent with the Louisiana Coastal Master Plan. The Mid-Breton Sediment Diversion will deliver sediment, freshwater, and nutrients to Breton Sound Basin in order to create, preserve, restore, and sustain wetlands and counteract the effects of subsidence, sea level rise, recent hurricane events, and the DWH oil spill. The Mid-Breton Sediment Diversion is needed as a long-term resilient, sustainable strategy to reduce land loss rates and sustain and restore wetlands.
This Permitting Dashboard includes limitations on the types of milestones that are currently available to enter for tracking. The Mid-Breton Sediment Diversion project involves some authorizations/laws unsupported by the Permitting Table displayed at the bottom of this webpage. For improved transparency, USACE is providing this supplemental table to track additional authorizations/laws that may be necessary for completion of the regulatory process:

CPRA begins consultation with NMFS on marine mammal impact minimizing, monitoring, and evaluation.
Following issuance of the MMPA waiver, the State will begin consultation with NMFS (using existing coordination processes to the extent possible) regarding practicable measures to minimize impacts to marine mammals, and measures to monitor and evaluate the impacts of the MBSD from construction, operation and maintenance. To date, the project sponsor has been in contact with NMFS about Phase I and Phase II marine mammal baseline data/monitoring.
