Why driveway markers matter most on Ottawa's newer suburban lots
Damage happens where the ground has not settled and the surfaces are new. On the newer lots in areas like Findlay Creek, Riverside South, Barrhaven South and Kanata Lakes the sod is a season or two old, the grading is still moving, and the interlock apron has not locked into a firm base yet. A plow edge riding a centimetre off the hard surface lifts fresh sod in a continuous strip, and a driveway edge that has settled unevenly gives the blade something to catch on. Older central neighbourhoods have the opposite problem: a narrow lot, a tight parking pad and a boundary that is only obvious to the person who lives there. Both cases are solved the same way, by putting the edge into the ground and into writing before the snow arrives, rather than arguing about it in the spring.
