Gila Street Improvements

The Gila Street Improvements project consisted of improvements along four separate streets located near downtown Yuma. In general, the design elements include following:

  • Demolition of approximately 800 LF of 8” PVC sewer line, 30 LF of 30” DIP waterline, cap and abandonment of a 16” CA waterline.
  • Design of approximately 1,400 tons of ½” and ¾ “Hot Mix asphalt pavement, 4,500 tons of ABC base and engineered subgrade. The design includes the mill and overlay on two separate streets and complete reconstruction on one street, curb to curb.
  • Design of 800 LF of 8” PVC sewer main, associated laterals and 6 sanitary sewer manholes. Sewer design included bypass requirements for bypass pumping operations.
  • Design of 300 LF of 8” PVC water main and associated laterals.
  • Design of striping and pavement markings.
  • Design of 4 new ADA compliant sidewalk ramps.
  • Evaluation and replacement of select, severely distressed Portland cement concrete sidewalk slabs, and curb and gutter.

Construction plans included plan and profiles, paving and grading plans, striping plans, phasing plan and associated details. All pre-design services were completed by Nicklaus including the Topographic Survey, Geotechnical Investigation and the coordination of utility locate services. The construction is complete and in use.
