About this file
This is a technical specification document for Type C Drive Approach construction standards established by Bountiful City, Utah, for use in street improvement projects involving sidewalk, curb and gutter, and storm drain facility work. The specification details the design and construction requirements for saw-cut curb drive approaches, including dimensional standards such as a 12-foot minimum to 30-foot maximum approach length, 6-inch minimum concrete thickness throughout, and 4-foot walkway widths with variable configurations. The document specifies material requirements including Class 4000 concrete per APWA Section 03304, 6-inch road base minimum, epoxy-coated rebar with #4 bars installed at specified spacing, 1/2-inch expansion joints at 4-foot intervals, and control joints required when driveway width exceeds 14 feet. Construction methodology requirements include compaction of existing subgrade to 95 percent minimum per Modified Proctor standards, curing via curing compound application per current APWA specifications, and saw-cutting of existing concrete or asphalt to full depth with straight lines and a minimum 3-foot width removal in front of drive approaches.
The specification mandates use of straight metal forms for all tangent sections or where curb radius is not less than 150 feet, reflecting standard municipal construction practices for consistent and durable drive approach installation. This technical standard was revised in August 2017 and serves as the governing specification for drive approach construction within the City of Bountiful's random-location street improvement projects, ensuring consistency and quality across multiple construction sites throughout the municipality.
