Stamped plans that keep permits and schedules moving.
When you need to work in the public right-of-way, a generic traffic control plan or a plan that does not meet the agency’s requirements can quickly lead to permit comments and delays. We deliver site-specific, PE-stamped plans prepared for the agency reviewing your work.
Where we fit in
We handle the transportation plans your permits depend on, coordinate delivery around your schedule, and support the submittal through agency review.
- PE-stamped traffic control plans for encroachment and right-of-way permits
- Plans prepared to the specific agency’s standards, not generic templates
- Turnaround coordinated around permit milestones and scheduled work windows
- A single engineering contact from initial submittal through comments and approval

Send project details
Share the project location, scope, reviewing agency, schedule, and any agency comments you’ve received. We confirm the plan type, required inputs, submittal path, and next steps.
AI-assisted plan production
Our engineers interpret the reviewing agency’s requirements, verify project inputs, and establish the design direction. They then use CPDG’s purpose-built AI platform to develop a coordinated draft plan set, including required notes, callouts, schedules, and supporting materials.
Structured quality and PE review
Automated checks look for missing information, conflicting values, incomplete notes, discrepancies across the plan set, and items that may not align with applicable jurisdictional standards and requirements. A licensed California PE then reviews the complete deliverable under responsible charge, resolves any remaining issues, and makes the final engineering decisions.
Submittal and support
You receive a coordinated plan package prepared for agency submittal. CPDG supports the project through agency comments, revisions, and approval.
