Per Wikipedia, the discrepancy is approximately 74 km, so digging a ditch with an average depth of approximately 74/2π ≅ 12 km around the circumference of the Earth would theoretically fix the problem.

Feasibility and geological implications are left as exercises for the reader.

Regardless, I suspect a more cost-effective fix would be to redefine the meter to be a couple "legacy" millimeters longer.
