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. Environmental Working Group - Comments and Response Summary An environmental working group was established to maintain open communication between the Town of Marana, ADOT, FHWA, resource agencies, and the project consultant team. The group met on three occasions (October 1, 2003, and January 8 and May 13, 2004). The major points from each of the meetings are summarized below. The first meeting was held on Wednesday, October 1, 2003. The meeting was attended by the Town of Marana, FHWA, ADOT, and the consultant team. Meetings with several of the property owners in the study area had been conducted and a summary of comments received from the property owners was discussed. Coordination with other projects within the study area (especially trail projects) was discussed. The second meeting of the group was held on January 8, 2004. The meeting was attended by the Town of Marana, FHWA, ADOT, and the consultant team. The meeting discussed relationships with the SNP and the proposed closure of Picture Rocks Road by the NPS. This issue is discussed in detail in Chapter 4, Affected Environment. Coordination with other ongoing projects in the study area was also discussed.

Public Involvement/Project Coordination October 2005 The third meeting of the environmental working group was held on May 13, 2004. The meeting was attended by the Town of Marana, FHWA, ADOT, USFWS, AGFD, and the consultant team. The intent of the meeting was to update all parties on the current status of the project and to solicit comments on the proposed design so that suggestions could be considered for incorporation into the project plans. The Town of Marana’s three year survey efforts for the CFPO were discussed. Coordination with other ongoing projects in the study area was discussed. Construction techniques and timing within the Santa Cruz River and maintenance or replacement of vegetation were discussed. The sizing of drainage facilities on both sides of the interstate to accommodate wildlife crossing was discussed. Scoping Meeting with Saguaro National Park - Comments and Response Summary At the request of the NPS, a meeting was held on November 13, 2003. Attendees included the Town of Marana, NPS, and the project consultant team. Project issues related to SNP are discussed in detail in Chapter 4, Affected Environment. The first public information meeting for the Twin Peaks Road TI was discussed. NPS supports the Twin Peaks Road TI and expressed a desire to close Picture Rocks Road through SNP after the TI is constructed. Technical Advisory Committee (TAC) Meetings - Comments and Response Summary The TAC was formed early in the project to help guide decisions. The TAC consisted of technically based individuals who participated in discussions and review of documents and concepts. Several potentially impacted agencies served on the TAC and this provided a broader perspective to the project. Members of the TAC included representatives from the Town of Marana, ADOT, FHWA, UPRR, PAG, PCDOT&FCD, and the consultant team. The TAC met on October 1, 2003 and on January 8, February 26, and May 13, 2004. Public Information Meetings A number of meetings with the affected community have been conducted. These have included a collective meeting with residential property owners, meetings with the Continental Ranch and Sunflower Neighborhood Associations, two public information meetings, two collective meetings with area business owners, and numerous meetings with individual residential property owners and business owners. Property Owner Informational Meeting - Comments and Response Summary Meetings with the Continental Ranch and Sunflower Neighborhood Associations were held on August 26, 2003 and August 27, 2003, respectively. A total of 20 attended the Continental Ranch presentation and approximately 100 attended the Sunflower presentation.
