River Rock for Landscaping Around Ann Arbor Clay
Most of Ann Arbor sits on heavy clay. Water sheets off it, puddles against foundations, and drags fine mulch right down the driveway. Rounded stone does not float, so river rock for landscaping is the usual fix for downspout splash zones, foundation strips and the low corner of the yard that stays wet into June.
In Water Hill and the Old West Side, lots tilt toward the old Allen Creek drainage that runs under the neighborhood. A dry creek bed of mixed river rock handles that runoff and still looks like it was meant to be there. If the bed under it needs work first, start with a layer of screened topsoil for Ann Arbor beds so the grade sends water where you want it.
