I-10 Twin Peaks Traffic Interchange, Environmental Assessment

Public Involvement/Project Coordination October 2005
(see Chapter 3, Preferred Alternative, page 3-11).
Comment: Concerns about increases in traffic noise (19 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: Questions about future traffic signals (11 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: Concerns about connections and effects to other roadways (11 comments)
Response: Connections to other roadways and the effects to other roadways were
considered in Chapter 2, Connectivity Section, page 2-6.
Comment: Concerns about increased traffic on Twin Peaks Road (10 comments)
Response: Because of the increase in traffic volumes predicted in the traffic report, a
number of improvements related to traffic signals, shared use paths, and other
improvements are proposed as a part of the preferred alternative (see Chapter 3,
Preferred Alternative, page 3-11).
Comment: Concerns about speeds on Twin Peaks Road (6 comments)
Response: No changes to the speed limits along the existing section of Twin Peaks Road
are proposed. The posted speed limit on Twin Peaks Road over the Santa Cruz River
would be 45 miles per hour.
Comment: Concerns about safety of children attending Twin Peaks Elementary School (4
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: Concerns about CFPO and wildlife movements (4 comments)
Response: As discussed in the Biological Resources section of Chapter 4 (page 4-25), the
analysis conducted for the preferred alternative determined that the proposed action may
affect, but is not likely to adversely affect the CFPO or its habitat due to the project
design and mitigation measures that would be implemented as a part of this project.
Comment: Questions about funding (4 comments)
Response: A combination of federal and local funds would be used on this project.
