Civil engineering for site, grading and drainage
Site plans, grading, drainage and utility designs prepared from your survey and building layout. Every slope, pipe and structure is shown so reviewers and site contractors can follow the design. [Confirm civil scope with AMG]

A site plan only helps if water goes where the plan says
AM's civil drawings show grades, drainage paths and utilities with the design basis on the sheets.
A site plan you have to interpret
What an unclear site design leaves open
? Where does stormwater leave the site?
? Do the finished grades drain away from the building?
? Was the storm system sized for the required design storm?
? Where do new utilities connect to the public mains?
? How much cut and fill does the grading need?
A design you can check
What AM Engineering delivers
✓ Existing and proposed grades shown on every sheet
✓ Drainage areas and storm calculations included
✓ Utility routes and connection points located
✓ Erosion control measures shown for construction
✓ Survey and soil assumptions stated on the drawings
What we design →
Six civil scopes for a buildable site
From the property line to the building pad.
Site plans
Building layout, parking, access and setbacks on the survey base.
Grading
Finished grades, building pads, slopes and cut and fill balance.
Drainage
Stormwater collection, pipes, inlets and detention or retention design.
Utilities
Water, sewer and storm connections from the building to the public mains.
Paving
Driveways, parking lots and sidewalks with pavement sections.
Erosion control
Sediment and erosion control plans for the construction phase.
How it works →
From survey to a checked site design in five steps
Every civil assignment follows the same review path.
1
Send your files
Boundary and topographic survey, building layout, geotechnical report and site address.
2
We confirm criteria
Local requirements, design storm, utility providers and deliverables.
3
We design
Grading, drainage, utilities and paving are calculated and drafted.
4
We check
Grades, pipe sizes and connections are checked against the survey and calculations.
5
You receive the package
Civil drawings and calculations ready for review. [Confirm PE stamp]
Revisions and plan review
Reviewer comments are answered with revised sheets and a response letter that records what changed.
Accepted inputs
Boundary and topographic surveys, architectural site plans, geotechnical reports and utility records.
What you receive →
What every civil package includes
Drawings and calculations issued together for the reviewer and the site contractor.

Why AM Engineering →
Built so the site drains as drawn
Seven habits that run through every civil package.
Water traced
Every drainage area is traced to a discharge point
Grades on every sheet
Existing and proposed grades are shown so a reviewer can check slopes
Calcs included
Stormwater calculations are issued with the drawings
Utilities located
Connection points to public mains are located and detailed
Survey-based
The design is built on your survey, with gaps listed as assumptions
Construction phase shown
Erosion control is drawn for the work, not only the finished site
Plan review support
Reviewer comments are answered with revised sheets and a response letter
FAQ →
Civil engineering questions
Surveys, drainage, permits and stamps.
Do I need a survey first?
Yes. A boundary and topographic survey is the base for grading and drainage design.
Do you design detention ponds?
Yes, where your jurisdiction requires detention or retention, sized from the stormwater calculations.
Can you handle site permits? [To confirm]
Confirm whether AM submits site permits or prepares drawings for the client to submit.
Do you design public road or utility extensions? [To confirm]
Confirm whether off-site public improvements are in AM's scope.
Do you stamp civil drawings? [To confirm]
Add the states where AM's engineers hold a PE license.
How long does a site design take? [To confirm]
Add typical turnaround for residential lots and commercial sites.
How is civil design priced? [To confirm]
Add the pricing basis, for example per acre or a fixed fee per site.
