The MOA submitted an initial Department of Army fill permit application for this project to the United States Army Corps of Engineers (USACE) in 2003. Since that time, Phase I has been in operation, Phase IIA was constructed, and Phase IIB will begin construction in summer 2017. 

In January 2011, environmental permitting activity resumed. Coordination with the USACE has continued through 2013 and a permit was issued on June 28, 2013.

Because the project corridor traverses North Klatt Bog (“Class B” wetlands), a Section 404 permit from the U.S. Army Corps of Engineers (USACE) is required prior to construction.  The Anchorage Wetlands Management Plan defines Class B wetlands as “having a moderate overall functional valuation, but still providing significant support to key watershed and drainage area functions.  Class B wetlands usually contain a mixture of wetland features reflecting both higher and lower functional performance.”

This project also falls within the Anchorage Coastal Zone boundaries, and will require a coastal consistency review from the Alaska Department of Natural Resources, Division of Coastal and Ocean Management.   This review process ensures that projects are in compliance with the Alaska Coastal Management Program’s statewide standards and the local enforceable policies of the Anchorage Coastal Management Plan.
