Drainage swale installation cost in Dallas-Fort Worth depends on length, depth, slope, soil movement, rock or grass finish, catch basin tie-in, erosion control, sod, utility conflicts, and whether the swale is part of a larger yard grading plan.
For planning, swales can range from a few hundred dollars for small shallow grading to several thousand dollars for longer rock-lined drainage paths. Larger yard drainage projects can include add-ons like sod restoration, downspout modifications, or sump pumps.

FAQ

A swale handles surface water; a French drain handles subsurface water. The right answer depends on the problem.
