Permits & Typical Steps

Most excavation in or adjacent to public streets, sidewalks or utility corridors requires an encroachment or grading permit and coordination with utilities. Typical steps are:

  • Apply for an encroachment or grading permit with Development Services or Public Works.
  • Provide plans, utility clearance, and traffic control details.
  • Pay application, inspection and restoration fees as required.
  • Schedule pre-construction and post-backfill inspections.
  • Complete backfill, compaction and surface restoration to city standards.
Apply early — permit review and bonded restorations can take multiple weeks.

Backfill Timelines & Inspection Sequence

Backfill and compaction are inspected in stages: open-trench inspection for shoring and utility work, a compaction inspection after successive lifts, and a final surface restoration inspection. Contractors should provide compaction test results if requested by the inspector.

  • Temporary backfill or trench plates may be allowed same day with an approved traffic control plan.
  • Permanent backfill typically requires compaction per the approved plan; timelines depend on testing and inspector availability.
  • If utilities must be exposed again, follow permit amendment procedures and re-inspection.
Compaction test reports help avoid rework and inspection delays.
