My yard in Brunswick floods after every big rain. Can grading fix it?

Usually, if there is somewhere for the water to go. Brunswick is flat and low, so the fix is rarely a steep slope; it is a gentle, consistent fall from the house toward the street, a ditch or a swale along the property line. We shoot the grades with a laser first to find where the water can actually exit, then shape the yard to get it there.

What if the whole neighborhood sits at the same level?

Then we build a swale, a shallow grassed channel that collects water and carries it to the nearest ditch or drain, and sometimes a French drain where a swale will not fit. Parts of Windsor Park, Dock Junction and the streets off Altama are like this, and the swale is what works there.

Will grading fix water under my house or against the slab?

Water against a foundation is the most important thing grading fixes. We create positive fall away from the house for the first several feet so rain leaves the foundation instead of sitting against it, and we route the downspouts to daylight rather than letting them dump beside the slab.

Can I just bring in fill and raise the low spot?

Sometimes, but not blindly. Much of Brunswick is in a mapped flood zone, and placing fill in a floodplain can need review because it pushes water onto neighbors. Raising a yard also does nothing if the water has no exit. We check the flood map for your lot and tell you whether fill, a swale, or both is the answer.

Do you build pads for sheds, slabs and driveways?

Yes. A pad in Brunswick's sandy soil has to be built in compacted lifts with the water table in mind, crowned so it sheds, and set high enough that the slab is not sitting in the wet. We also handle the driveway apron and culvert where a county road is involved.

Land grading in Brunswick, GA: getting water off a flat, low lot

Brunswick does not have slopes to work with. Grading here is the art of making a few inches of fall do the job of a hill.

Most of Brunswick sits within a few feet of sea level on ground that is nearly flat, over a water table that rises to the surface after a summer thunderstorm. That is why yards in Windsor Park, Dock Junction, Old Town and the subdivisions along Altama Avenue hold water for days, why crawl spaces stay damp, and why fences and sheds tip in the wet corners. Golden Isles Fencing and Excavation grades lots across Brunswick, and the work is almost never about moving a lot of dirt. It is about finding where the water can leave and shaping the yard so it does.

We are a family-owned, Christian-based company based in Brunswick, and because we build fences and pads here too, we know what happens to a fence post or a slab that sits in standing water every June.

Finding the exit

Every grading job in Brunswick starts with a laser level and a question: where can the water actually go? On some lots it is the street, on some it is a county ditch behind the property, on some it is a storm drain at the corner. On a few, honestly, there is no good exit, and the answer is a swale to the lowest available point and patience. We shoot the grades across the yard and the neighboring ground before we touch it, because raising a yard that has no outlet just moves the puddle to the neighbor, and in a city this flat that starts arguments.

Positive fall away from the house

The single most valuable thing grading does on a Brunswick lot is protect the foundation. We create a consistent fall away from the house for the first several feet in every direction, so rain leaves the slab or the crawl space instead of sitting against it, and we extend the downspouts to daylight so the roof water is not dumped beside the foundation. On the older raised houses in Old Town this is often the difference between a dry crawl space and one that never dries out.

Swales and French drains for lots with nowhere to go

Where the whole street sits at the same level, the tool is a swale: a shallow, grassed channel along a property line or across the low side of the yard that collects water and carries it to the nearest ditch or drain at a gentle grade. It mows like the rest of the lawn and most people stop noticing it. Where there is no room for a swale, or a driveway crosses the path, we install a French drain, a gravel trench with perforated pipe, to carry the water underground to an outlet. Both are common in Brunswick and both work when the grades are right.

Fill and the flood map

Homeowners often ask us to bring in a few loads of fill and raise the low spot. Sometimes that is right. But much of Brunswick sits in a mapped flood zone, and placing significant fill in a floodplain can require review because it displaces water onto adjacent lots. Fill also does nothing if the water has no exit; it just makes a higher puddle. We check the flood map for your parcel, and if fill is part of the answer we place it in compacted lifts and shape it to drain rather than dumping and spreading.

Pads for slabs, sheds and driveways

A building pad in Brunswick's sandy soil is built in compacted lifts, crowned so it sheds water, and set high enough that the slab is above the seasonal water table rather than in it. We strip the topsoil and organics first, because a pad built on them settles. For driveways we build the base to drain, and where a county road is involved we handle the apron and the culvert under it, which needs a county right-of-way permit that we take care of.

Permits and the wet edges

Reshaping a residential yard for drainage often needs no permit. Grading a larger area, placing significant fill, or working near a ditch, creek or marsh brings the City of Brunswick or Glynn County land disturbance rules into play, and Georgia's buffer along creeks and marsh restricts disturbance near the edge. Lots near Terry Creek, Academy Creek and the marsh behind Blythe Island are the ones to be careful with. We tell you what applies before we quote.

How a Brunswick grading job runs

Shoot the grades. Laser level across the lot and the neighbors' ground to find the outlet.
Plan the flow. Fall away from the house, a swale or drain to the exit, fill only where it helps.
Utilities and permits. Locate called in, permit confirmed if the job needs one.
Grade. Topsoil stripped where a pad goes, fill placed in lifts, surfaces shaped and compacted.
Finish. Downspouts extended, swale seeded or sodded, site cleaned.

If your Brunswick yard holds water, send us a photo after the next rain and your street. Estimates are free, and if a fence is going in afterward we will look at that on the same visit.
