About this file
This is a Standard Detail specification document prepared by the City of West Sacramento, California, for driveway construction with curb and gutter separate from sidewalk installations (Detail #205). The specification outlines construction requirements for both residential and commercial/industrial driveways, establishing minimum material standards and installation procedures. Residential driveways must be 6 inches thick concrete at 4,000 PSI minimum, while commercial/industrial driveways require a minimum of 8 inches thick with #4 rebar spaced 12 inches on center in both directions. All driveways must be placed on a minimum 6-inch compacted Class II aggregate base over 6 inches of subgrade, with all base materials and subgrade processed to 95% relative compaction. The specification addresses driveway width requirements, sidewalk compatibility, curb height standards (6 inches standard), slope limitations (10% maximum without City Engineer approval), and finishing requirements including light broom finishes applied perpendicular to the street centerline for sidewalk areas and parallel to the roadway centerline for driveway, curb, and gutter areas.
The document provides detailed technical requirements for doweling connections between new driveway sections and existing concrete through rebar installation via coring or drilling methods, with rebar placement in existing concrete using epoxy to fill annular voids. Specific construction procedures include sawcutting and removal of existing street sections, placement of minimum 6-inch thick asphalt concrete patches, and joint and score marking specifications with deep tool joints at 1-1/2 inches minimum. The standard detail was approved August 2025 and is referenced in conjunction with Standard Detail #202 for concrete, base, and subgrade installation specifications, establishing comprehensive guidelines for contractors bidding on the City of West Sacramento's CFD Sidewalk Replacement 2026 project.
