Grading and Drainage Checklist
Grading and Drainage Checklist
Quick Summary
Proper grading and drainage help prevent standing water, erosion, foundation issues, and costly callbacks. This checklist helps crews verify site elevations, drainage flow, soil conditions, compaction, and final grading. It is useful for excavation contractors, landscapers, sitework crews, foremen, and project managers.
When to Use This Checklist
- Before starting site grading work.
- During drainage improvement projects.
- When preparing building pads or landscape areas.
- Before installing sod, seed, hardscape, or paving.
- During sitework quality-control inspections.
- Before customer walkthroughs.
- Prior to project closeout.
Before You Start
- Review grading plans, drainage details, and project scope.
- Verify benchmark elevations and reference points.
- Inspect existing site drainage conditions.
- Identify low spots, erosion areas, and drainage concerns.
- Confirm equipment, materials, and crew availability.
- Verify utility locates have been completed if needed.
- Check weather forecasts and site moisture conditions.
Safety Checks
- Inspect grading and excavation equipment before use.
- Maintain safe distances from utilities and structures.
- Use proper PPE for excavation and grading activities.
- Control equipment traffic and work zones.
- Monitor slopes and excavation areas for stability concerns.
- Keep personnel clear of active grading operations.
Tools, Equipment, and Materials
- Skid steer, loader, excavator, or grading equipment.
- Laser level, transit, or grade measurement tools.
- Compaction equipment.
- Drainage pipe, catch basins, or drainage materials.
- Aggregate, fill material, or topsoil as specified.
- Layout stakes, marking paint, and string lines.
- Project plans and grading details.
Grading and Drainage Checklist
- Verify grading limits and layout match project plans.
- Remove debris, vegetation, and unsuitable materials.
- Establish rough grades according to design elevations.
- Verify positive drainage away from buildings and structures.
- Eliminate low spots that may collect standing water.
- Install drainage swales, channels, or berms as required.
- Install drainage pipe and structures according to plans.
- Verify drainage outlets are clear and functional.
- Place and compact fill materials as required.
- Check final elevations against project requirements.
- Inspect slopes for smooth transitions and consistent grades.
- Verify erosion-prone areas have been addressed.
- Test drainage flow where practical.
- Correct grading or drainage deficiencies before completion.
- Perform a final site grading and drainage inspection.
Documentation Needed
- Approved grading and drainage plans.
- Elevation and grade verification records.
- Material delivery records.
- Before, during, and after photos.
- Drainage testing notes and inspection records.
- Customer approvals and closeout documents.
Common Mistakes to Avoid
- Creating low areas that trap water.
- Failing to maintain positive drainage away from structures.
- Skipping compaction of fill materials.
- Ignoring existing drainage patterns.
- Improper drainage outlet placement.
- Failing to verify final elevations before project completion.
End-of-Day / Final Review
- Final grades match project requirements.
- Drainage systems have been inspected and tested.
- Standing water areas have been eliminated.
- Photos and project records have been saved.
- Site cleanup has been completed.
- Project is ready for final inspection and customer handoff.
