Wetland Resources

Auburn-Lewiston Municipal Airport

CES, Inc. recently teamed with Hoyle, Tanner & Associates, Inc. (HTA)  to successfully provide an environmental study and to permit the construction of a new parallel taxiway and apron expansion at the Auburn-Lewiston airport. This much needed safety project was under intense deadline pressure to complete the permitting process within FAA grant timelines. CES, Inc. completed wetland delineation and critical habitat surveys, and mapped natural resources areas and significant wildlife habitat on the project site. CES combined GIS data from State and municipal agencies, and local environmental resources to identify the suitable sites. Using GIS, CES analyzed available data to refine the search and maximize ecological/environmental benefits for the region and the community while meeting regulatory goals. Visual displays were then created to highlight the key components of mitigation sites within a watershed context for community, municipal, State, and Federal groups.

CES and HTA coordinated environmental alternatives analysis, and worked with local conservation groups, wildlife biologists, City officials and State and Federal agencies to minimize impacts and move the project forward and complete the permitting on time. CES coordinated all phases of the archeological investigation with research team from the University of Maine at Farmington Archeological Resource Center. CES also provided technical support on the Airport’s Site Location of Development Permit and performed a boundary survey for the mitigation site.

A major factor in approval was a successful mitigation plan to compensate for unavoidable wetland impacts and lost habitat. Through a partnership with the Androscoggin Land Trust and the City of Auburn, a plan was implemented to protect over 25 acres of undeveloped forest near an existing preserve in the heart of Auburn’s downtown and to restore riparian habitat along Moose Brook. The project also incorporated critical habitat protection and implemented Best Management Practices for airport maintenance to improve the habitat for the Upland Sandpiper, a State threatened species.  By working together and coordinating efforts with many diverse groups, the taxiway project was ultimately successful in reducing environmental impacts and meeting the project goals on time.
