Do I need a permit to build a stream crossing in Georgia?

Usually. Work in or near a state waters channel typically involves buffer requirements and county land-disturbance review, and federal permitting can apply. We confirm what your specific crossing needs before designing it.

Culverts keep access dry year-round and suit daily use. An armored ford can be appropriate for occasional farm access on a wide, shallow channel where a pipe would be impractical.

Why did my last crossing wash out?

Nearly always undersized openings, a poorly compacted fill, or no end protection. Water that cannot get through goes over and takes the fill with it.

What is a rolling cross-drain?

A shallow grade break built into a road or driveway that turns water off the surface at intervals. On long slopes they prevent the runs of flow that cause scour.

Property access

Stream Crossings & Cross-Drain Installation in North Georgia

Permitted stream crossings, sized culverts, fords and cross-drains that carry farm access over water without annual repairs.

A crossing is the highest-consequence piece of infrastructure on most rural properties. Get it wrong and you lose access, lose the fill, and create a compliance problem downstream. Get it right once and it is the least interesting thing on the place.

Part of our Estate Driveways & Property Access in North Georgia work across North Georgia.

What we see most often

Crossings washed out or impassable after heavy rain
Undersized pipe damming flow and blowing out the fill
Unstable approaches dumping mud and silt straight into the creek
Work done without permits on a regulated stream

Scope of work

What this work includes

Crossing type selection

Culvert, multi-pipe, bottomless arch or armored ford chosen from flow, channel shape and how the crossing gets used.

Hydraulic sizing

Contributing watershed and design storm used to size openings so the crossing passes flow instead of backing it up.

Approach stabilization

Stone, matting and grade breaks on both approaches so runoff and sediment do not run directly into the channel.

Permitting & controls

Coordinating required approvals and installing the erosion and sediment controls the work calls for.

A crossing that passes the storm, keeps the creek clean, and does not become an annual project.

How it goes

Our process

Step 01
Survey the channel
Measure section, slope and high-water marks.
Step 02
Design & permit
Size the structure and clear it with the authority having jurisdiction.
Step 03
Build in the dry
Divert or time the work, then set and backfill the structure.
Step 04
Armor & stabilize
Riprap the ends, stone the approaches, seed the disturbance.
