I-10 Twin Peaks Traffic Interchange, Environmental Assessment

Public Involvement/Project Coordination October 2005
included: Marana Town Council, Marana Town Manager, Marana Public Works
Department, Marana Planning Department, Marana Police Department, PAG,
PCDOT&FCD, ADOT, Northwest Medical Center, and Trico Electric. Correspondence
received from agencies in response to this request may be found in Appendix A.
The intent of the agency scoping meeting was to obtain comments or concerns to be
considered in the development of the Design Concept Report and environmental
documents for the Twin Peaks Road TI. The meeting goals were to inform the agencies
of the proposed project and to establish communication lines between the project
development team and the concerned agencies. Several TI design concepts including
shifting the I-10 alignment, an elevated or depressed crossroad over or under I-10, grade
separation with the UPRR, and the use of a SPUI were discussed. These items have been
considered and are addressed in Chapter 3, Alternatives.
Special Environmental Scoping Meetings - Comments and Response Summary
A meeting was held on Monday, August 25, 2003 at FHWA offices in Phoenix to
coordinate environmental efforts currently taking place on the Twin Peaks Road TI
project. Attendees included the Town of Marana, FHWA, AGFD, Corps, ADOT, and the
consultant team. The meeting discussed the proposed project’s background, proposed
scope, and issues. The meeting asked for comments on the proposed project approach.
The level of environmental effort was discussed, both in general (e.g. environmental
assessment versus environmental impact statement) and specific to particular issues (e.g.
biological evaluation).
A follow–up meeting was held on September 2, 2003 with agencies unable to attend the
August 25 meeting. The meeting was attended by the Town of Marana, USFWS, ADOT,
and the consultant team. The routing and review of environmental documents was
discussed. The content of biological investigation documents was discussed and
agreement was reached on content and species to be considered. Methods of possible
mitigation for removal of vegetation were discussed.
