Crawford sits where State Highway 317 meets FM 185, eighteen miles west of Waco, with the Middle Bosque passing just north of town. The prairie starts to roll here, and the clay gets thinner.
The Middle Bosque River heads in Coryell County and runs thirty-nine miles southeast, north of Crawford, to Lake Waco. The Handbook describes the country it drains as rolling prairie surfaced by deep to shallow clay and clay loam, with oak and juniper on it, before it flattens out toward the lake. That sentence is a fair summary of Crawford's drainage: the ground has slope, which is good, and the clay over it varies from deep to shallow, which means no two lots behave alike.
Crawford itself began at Tonk Crossing, a ford of the Middle Bosque two miles east of the present town, and moved to the railroad in the 1880s. The river has been the reference point for this community from the start.
On the rolling ground west of Waco the NRCS maps Heiden clay across footslopes and side slopes, on grades from half a percent to twenty percent, often with limestone or chert fragments on the surface. It is well drained in the sense that water runs off it - runoff is rated very high on any real slope - but its permeability is still very slow, so what does not run off sits. Downslope, the deeper clay and clay loam collects everything the hillside sheds.
For a Crawford lot, that means the question is rarely 'will water stand?' and more often 'where is the water from uphill going, and is my house in the way?' Erosion on the slope and ponding at the toe are two ends of the same problem. Before we design anything we probe the depth to rock, because a trench that is easy through two feet of clay stops dead when it hits limestone, and that sets how deep and where a drain can run.
A lot of Crawford property is acreage with a house set back off the road, and the driveway and the pad are usually where the trouble starts. A drive cut across the slope acts as a dam; a pad scraped level on a hillside leaves the uphill side catching water it cannot pass. Swales and regrading that give that water a route around the house are the backbone of the fix, with a French drain on the uphill side of the slab where seepage keeps coming through the subsoil.
Where there is enough fall - and in Crawford there usually is - we daylight the drain at a low point on your own land rather than relying on a pump.
The Handbook notes that Crawford's population rose sharply in the 1980s as people chose to live here and commute to Waco or McGregor. Houses from that wave are now old enough that original grading has settled, gutters have been added or replaced and trees have grown in. If yours has developed a soft corner or water at the slab after a storm, foundation drainage - fall restored around the perimeter, downspouts carried well away - keeps the shrink-swell swing in the clay from working on the foundation.
