Civil & Site Engineering
Site plans, grading, drainage and stormwater design for the ground a project sits on.
What happens outside the building envelope decides approvals as often as what happens inside it. Grading, drainage and stormwater get engineered against the actual conditions of the site, which on Long Island frequently means working around a high water table.
Scope
- Site plans and zoning compliance analysis
- Grading and earthwork design
- Drainage and stormwater management
- Groundwater separation analysis
- Driveways, parking and loading layouts
- Retaining walls and site structures
- Erosion and sediment control

Common questions
Why is drainage part of my building permit?
Because what you build changes where water goes. Most jurisdictions require stormwater to be managed on site rather than pushed to a neighbour.
What is groundwater separation?
The vertical distance between a structure and the water table. On much of Long Island it is close enough to drive design decisions.
