Grading, Drainage & Civil Permit Plans
Site Plans Online USA prepares grading, drainage and civil site documentation for residential and commercial permit projects across the United States. Depending on the property and jurisdiction, a project may require more than a basic plot plan. Drainage patterns, finished elevations, access, parking, utilities, stormwater or erosion-control information may need to be coordinated with the permit set.
What We Can Prepare
- Existing and proposed grading plans
- Drainage direction and surface-flow coordination
- Finished-floor and spot-elevation coordination
- Stormwater and retention/detention layout support
- Driveway, paving and parking plans
- Accessible parking and route coordination
- Erosion and sediment-control sheets
- Utility and service coordination
- Floodplain and elevation-note coordination
- Site-development plans for residential and commercial projects
When Civil or Drainage Plans May Be Needed
Civil information may be requested when a project changes site drainage, adds substantial impervious area, modifies parking or access, introduces a new building pad, affects floodplain conditions, or requires stormwater review. Requirements vary by authority having jurisdiction, so the project address and reviewer requirements should be checked before the final scope is confirmed.
Typical Deliverables
A civil permit package may include a cover sheet, existing-conditions plan, proposed site plan, grading plan, drainage notes, spot elevations, parking or paving layout, erosion-control information, utility coordination and applicable details. Professional engineering review can be coordinated where required, available and included in scope.
What We Need From You
- Property address
- Survey or boundary information, if available
- Existing topographic or elevation information, if available
- Project scope and proposed improvements
- Photos, sketches or existing plans
- Permit comments, if the project has already been reviewed
Residential & Commercial Projects
We support grading and drainage needs for additions, detached structures, pools, driveways, parking improvements, commercial tenant work, new buildings, metal buildings and broader site-development projects.
Permit Corrections & Resubmittals
If the reviewing authority has already issued drainage, grading or civil comments, send the complete comment letter and current plans. We can identify the affected sheets and prepare applicable updates within the agreed scope.
