Storms off the Sound stack up fast against the red rock west of Hamden, and in Highwood the streets run tight with parking close on both sides. PMG Properties handles the snow work there: plowing driveways and lots, clearing sidewalks and entries, shoveling out the steps, and salting before the overnight freeze locks everything in place. In a dense neighborhood the skill is in where the snow goes — banked clear of the mailbox, off the apron, out of the sightline at the corner. Nobody thinks about it when it is done well, and that is the standard the work is held to. Hamden wakes up, backs out, and gets on with the day.
