Stabilizing a Wet, Weedy Area with Groundcovers and Grasses

A homeowner removed weed mat and chips from a wet area; chips washed into neighbor's yard. Now only weeds and mud remain. They want a low-maintenance solution without herbicides.

Replace weeds with groundcovers or grass. Groundcovers: creeping phlox, sedum, creeping thyme, veronica, periwinkle, wintercreeper, ice plant. Grasses: English rye, Kentucky bluegrass, blue sheep fescue, rough meadow grass, sedges/rushes (some for wet soil), sweet vernal grass. These hold soil and prevent erosion.
