Excavation for Lake Oconee homes and lots: walkout basements, foundations, septic systems and utility trenches on sloping lake ground.

Lake Oconee touches Greene, Morgan, Putnam and Hancock counties. Septic on a lake lot answers to the county health department and, on project land, to Georgia Power.

The short answer

What should Lake Oconee owners know before hiring excavation?

Every dig starts with a Georgia 811 locate request at least three business days ahead. Trenches 5 feet or deeper need cave-in protection, and nothing can be dug, piled or graded on Georgia Power land or in the 25-foot buffer without its approval. A Class Septic handles basements, foundations, septic and utility excavation around the lake.↗↗↗

The Lake Oconee story

The walkout basement and everything under it

The typical new Lake Oconee house is cut into a slope with a walkout basement facing the water. That means a deep cut on the uphill side, a lot of spoil, and a driveway that has to carry dump trucks down a grade that was never meant for them.

The ground around the lake usually digs well. DPH's soil table lists Cecil and Pacolet, common Piedmont upland soils, with bedrock deeper than 60 inches. Weathered rock still shows up in cuts near ridgelines and stream crossings, and the plan should leave room for it.↗

Spoil placement is where lake jobs go wrong. Piling clay near the water or pushing it toward the shoreline to flatten a yard runs into Georgia Power's rule against changing the land contour in its buffer or on its land. We plan the haul-off before the first bucket.↗

On the record

  • Boathouses are not permitted on Lake Oconee except for original property owners or their heirs who still own the lot, and those must follow Lake Sinclair's boathouse specifications.↗
  • A drain field has to stay at least 10 feet from a building with a basement, versus 5 feet from one without, so the basement decision moves the septic layout too.↗

Permits · Georgia 811, OSHA, the county land-disturbance office and Georgia Power

Before and during the dig

  1. 01

    Call 811 or file online at least three business days ahead; business days run Monday to Friday, 7:00 a.m. to 4:30 p.m., and a request after 4:30 counts as the next day.↗

  2. 02

    A locate ticket is good for 30 calendar days; inside 18 inches of a marked line, dig by hand, vacuum or other soft methods only.↗

  3. 03

    Utilities get a second chance to respond until noon on the ticket's effective date; with no sign of unmarked lines, careful digging can begin after that.↗

  4. 04

    On the Greene shore, file an erosion plan and land disturbance permit when the work is within 200 feet of state waters or tops one acre.↗

  5. 05

    Shore, slope or shield any excavation 5 feet or deeper unless it is entirely in stable rock.↗

More about Lake Oconee

Private lines that 811 won't mark

Georgia 811 locates utility-owned lines. On a lake lot, the lines most likely to be hit are private: the power and water run to the dock, an irrigation pump line, the septic force main, low-voltage lighting. Georgia 811 notes that service lines past the meter are generally private and need a private locate.↗

In the trench, OSHA keeps spoil and equipment at least 2 feet back from the edge. A trench 4 feet or deeper needs a ladder or ramp within 25 feet of lateral travel, and a competent person inspects it daily.↗

  • Georgia 811 says dents, scratches and gouges to a buried pipe count as damage: stop digging and report it to 811 and the line's owner right away.↗
  • Georgia Power can permit dredging of up to 500 cubic yards per property; more needs approval from the U.S. Army Corps of Engineers and FERC, and spoil must go off Georgia Power land or at least 25 feet from the lake.↗
  • Dredged silt may not be used to backfill seawalls or to level up land.↗

Will 811 mark the line to my dock?

Usually not. Lines past the meter are generally private and need a private locate service.

Can the dirt from my basement be spread down toward the lake?

Not into the 25-foot buffer or onto Georgia Power land. Georgia Power bars changing the land contour there without written approval.

Can I dredge my cove for deeper water at the dock?

Georgia Power can permit up to 500 cubic yards per property with an approved plan, only to remove accumulated sediment, with a turbidity barrier in place.

When does a trench need shoring?

At 5 feet deep or more, unless it is entirely in stable rock. Sloping without other analysis can be no steeper than 1.5 to 1.

Can I build a boathouse on Lake Oconee?

Generally no. Georgia Power permits them only for original property owners or their heirs who still hold the lot.
