Public Involvement/Project Coordination October 2005 Comment: Concerns about amenities – park facilities (1 comment) Response: Project amenities are discussed in Chapter 3, Preferred Alternative, page 3- 11). Comment: Expressed desire to receive information from website (1 comment) Response: The Town intends to establish a website for this project, but one has not yet been established. During the initial public information meeting, concerns were expressed regarding the safety of children attending Twin Peaks Elementary School. As a result, the Town of Marana chose Twin Peaks Elementary School as their initial Safe Routes to School program and a “Safe Routes to School” committee was formed. The committee consisted of representatives from the Town of Marana’s Engineering staff, Twin Peaks Elementary School staff (the Principal and a teacher), a parent of a student at Twin Peaks Elementary School, the Marana Unified School District’s Facilities and Transportation Department, the Marana Police Department, and an engineering consultant. The committee recommended the construction of a 4,500-foot long, 14-foot wide shared use path along the south side of Twin Peaks Road from Silverbell Road to Coachline Boulevard and along Coachline Boulevard from Twin Peaks Road approximately 725 feet to the south. The shared use path was discussed subsequently with the Town of Marana’s Parks and Recreation Department and nearby homeowners associations. As the design of the shared use path advances, an open house would be held to solicit additional input from the community. The Town participated also in a School Safety Day held at Twin Peaks Elementary School as part of the educational efforts initiated by the Town. Although the Twin Peaks Road TI project does not provide funding for this shared use path, the social, economic, and environmental effects of this path are addressed within this document to increase the probability of the grant application’s success. Public Information Open House #2 - Comments and Response Summary Approximately 135 people attended an open house on March 22, 2004 at Twin Peaks Elementary School, 7995 W. Twin Peaks Road. A presentation on the status of the project, project schedule, and Twin Peaks Road TI location alternatives was given at 7:00 p.m. The project team was available before and after the presentation to answer questions and receive comments from open house participants. Comment forms were available for participants to record any comments or ask any questions. The public was asked specifically to comment on the three Twin Peaks Road TI alignment alternatives presented. The most common comment, as it was in the first public information meeting, was that the TI should be constructed as quickly as possible. Notifications were mailed to approximately 700 residents, businesses, and government agency personnel who are stakeholders in the project or who had expressed interest in the project. Newspaper advertisements were placed in the March 7, 2004, Sunday Arizona Daily Star and the weekly Northwest Explorer newspapers on March 10, 2004. The advertisements for the meeting may be found in Appendix A. Interstate 10 Traffic Interchange at Twin Peaks/Linda Vista 5-8 Project No.: NH-010-D (AIW) TRACS No.: 10 PM 236 H5838 01D
Public Involvement/Project Coordination October 2005 Comment: Preference expressed for the center alternative (18 comments) Response: The center alignment was selected as the preferred alignment (see Chapter 3, Alternative TI Alignments, page 3-6) Comment: Preference expressed for the south alternative (12 comments) Response: The center alignment was selected as the preferred alignment (see Chapter 3, Alternative TI Alignments, page 3-6) Comment: Concerns about increases in traffic noise (5 comments) Response: The traffic noise analysis determined that future traffic noise levels in the area would increase and mitigation has been recommended (see Chapter 4, Noise Section, page 4-49). Comment: Provide an intermodal center (3 comments) Response: An intermodal center is not proposed as a part of the preferred alternative because of the additional project costs and because there are no current plans to increase mass transit into the area.. Comment: Questions about future traffic signals (3 comments) Response: The traffic report recommended future traffic signals at the intersections of Twin Peaks Road with Silverbell Road, Coachline Boulevard, Access Road, eastbound and westbound I-10 frontage roads, and El Camino de Mañana/Linda Vista Boulevard (see Chapter 3, Proposed Intersection Improvements, page 3-17). Comment: Questions about funding (3 comments) Response: A combination of federal and local funds would be used on this project. Comment: Concerns about lighting (3 comments) Response: New intersection lighting would be provided at all signalized intersections within the study area (see Chapter 3, Proposed Lighting Improvements, page 3-20). Comment: Concerns about safety of children attending Twin Peaks Elementary School (2 comments) Response: According to the Traffic Report, most pedestrian and bicycle traffic to Twin Peaks Elementary School originates south and east of the school. A shared use path was proposed south of Twin Peaks Road, but is not a part of this project (see Chapter 3, Preferred Alternative, page 3-11). The proposed traffic signals at the intersections of Twin Peaks Road/Coachline Boulevard and Twin Peaks Road/Silverbell Road would enable pedestrians to safety cross at these intersections. The Town would work closely with the Marana Unified School District on appropriate crossing measures. Comment: Preference expressed for the north alternative (2 comments) Response: The center alignment was selected as the preferred alignment (see Chapter 3, Alternative TI Alignments, page 3-6) Interstate 10 Traffic Interchange at Twin Peaks/Linda Vista 5-9 Project No.: NH-010-D (AIW) TRACS No.: 10 PM 236 H5838 01D
