Key takeaways
- Grading design must coordinate drainage, buildings, roads, utilities, accessibility, and neighboring property.
- Reliable survey and jurisdiction criteria are foundational inputs.
- Stormwater calculations must match the elevations and facilities shown on the plans.
Why grading is more than drawing contour lines
Site grading establishes how people, vehicles, water, buildings, utilities, and landscapes fit together vertically. A local change intended to solve one drainage problem can create ponding, inaccessible slopes, utility conflicts, or discharge onto adjacent property.
The engineer should use current survey information and the reviewing authority's drainage, stormwater, erosion-control, and accessibility criteria.
Site-civil review checklist
Coordinate plans and calculations from the same survey, design surface, and drainage assumptions.
- Boundary and topographic survey with benchmarks and existing drainage features
- Finished floors, pavement, walks, ramps, walls, slopes, and tie-in elevations
- Existing and proposed drainage areas, flow paths, and discharge points
- Storm sewer, inlet, culvert, swale, detention, and outlet information
- Hydrology, hydraulics, storage, water-quality, and erosion-control calculations
- Utilities, easements, flood information, soils, landscaping, and construction phasing
Check downstream and neighboring impacts
The design should consider where runoff goes after leaving the site, whether receiving systems have constraints, and how construction-phase drainage differs from final conditions. Jurisdictions may require additional reports or approvals for floodplain, wetland, or off-site work.
Frequently asked questions
Do residential grading plans need a PE stamp?
Requirements vary by jurisdiction and scope. Steep sites, drainage changes, walls, flood conditions, or engineered stormwater systems commonly increase professional-design requirements.
Can grading be finalized before the building plan?
Preliminary coordination is possible, but final footprints, finished floors, entrances, utilities, roof drainage, and accessible routes should be coordinated before issuance.
