The history is that the HOA clears sidewalks near parks (not the walking trails), green courts, townhouses (no matter what they're called) and areas where there are no houses abutting the sidewalks (i.e. the lake and the weed field near the DCC). The HOA has sent out emails and postings to that effect. It takes days, sometimes.
Homeowners must (per HOA rules and city codes) shovel their own sidewalks within stated time frames. Questions can be directed to the HOA at 254-8062;Shirley can answer your questions. If your sidewalk, miraculously, got cleaned it was a kind neighbor.
Every now and then, when I'm out plowing and see someone struggling with walkways, I'll stop and pitch in but I have more time than sense, I suspect. Many folks help out those around them. It's a Daybreak thing.
