Livermore Excavation and Storm Drain Permit Guide
This guide explains excavation permits, restoration timelines, and storm drain obligations for projects in Livermore, California. It summarizes what triggers a permit, typical restoration and inspection steps, how storm drain protections and temporary controls apply during work, and where to submit applications or complaints. Use this as a practical roadmap for homeowners, contractors, and engineers to plan compliant excavation and restoration work within Livermore city limits.
When a Permit Is Required
Excavation, trenching, and any work in or under the public right-of-way or that affects storm drainage typically require an encroachment or excavation permit from the City. Permits cover temporary shoring, backfill, pavement restoration, and any connections to storm drain infrastructure. For legal requirements and penalties see the municipal code and the City Public Works permit pages. City of Livermore Municipal Code[1] Encroachment and excavation permits[2]
Typical Permit & Restoration Timeline
- Apply: submit permit application and plans (allow 7-21 business days for review depending on scope).
- Review: engineering review for shoring, traffic control, and stormwater measures; revisions may be requested.
- Inspection: pre-pour and final inspections scheduled by the City; do not cover trenches until inspected.
- Restoration: comply with City standards for pavement, curb, sidewalk, and landscaping restoration.
Storm Drain Protections During Work
Work that can discharge sediment, concrete wash, or other pollutants to the storm drain system must use best management practices (BMPs) such as silt fences, inlet protection, and stabilized entrances. Temporary controls must be maintained until the site is permanently stabilized. Follow City stormwater rules and erosion control requirements set by the municipal code and Public Works permit conditions.[1]

Applications & Forms

Common Violations
- Working without an encroachment or excavation permit.
- Improper backfill or failure to restore pavement and sidewalks to City standards.
- Allowing sediment, concrete wash, or pollutants to enter the storm drain system.
FAQ
- Do I need a permit to dig on my property?
- If excavation affects the public right-of-way, storm drains, or requires work on sidewalks, curb, or pavement you must obtain the City encroachment/excavation permit; private property-only small landscaping digs may not require it but check with the Building Division.
- How long does pavement restoration take?
- Restoration scheduling depends on weather and City inspection availability; permanent pavement is usually scheduled after passing required compaction and base inspections and once surfaces are accepted by the inspector.
- Who inspects stormwater controls?
- Public Works inspectors and Building Division inspectors check temporary BMPs and final stabilization as part of the permit inspections.
How-To
- Prepare plans: site plan, traffic control, erosion and sediment control, and restoration details.
- Submit application: file the encroachment/excavation permit application with Public Works and pay applicable fees.
- Schedule inspections: request pre-work and final inspections as required by your permit.
- Complete restoration: perform restoration to City standards and obtain final sign-off.
Key Takeaways
- Always check for an encroachment permit before work that affects public right-of-way or storm drains.
- Plan for reviews and inspections—allow time for revisions and scheduling.
- Unpermitted work can trigger orders, fines, and mandatory costly restoration.
