A door in this city sits anywhere from one riser to seven above the path, and the path is on sand. Those are the two facts a flight here is built around, and the second is the one that undoes it.
Around the Plaza the houses went up between the 1900s and the 1920s on raised wood floors, so the front door stands three or four feet above the walk and the flight has five, six or seven risers with a porch at the top. The tracts that ring Old Towne were poured on slabs, and their doors sit one or two risers up. East of the 55 the hill tracts sit on pads, and the stair there is often in the side yard, dropping from a driveway to a terraced garden. The height is set by the era.
The ground is not. Under the flat of the city the walk sits on Santiago Creek wash, sand and rounded gravel that drains fast and compacts poorly, and a path poured on it in 1965 has been dropping ever since while the house beside it, on a footing, has not. Ours sits on its own footing below the path, doweled to the porch, so the heights set on the story pole are the ones a foot finds in twenty years. Where a flight climbs a bank the retaining wall shares its footing.
