Weather reaches Paterson from the west, over the shoulder of Garret Mountain, and from the ridge you can watch it coming down onto the flats. SALINAS LANDSCAPING LLC keeps an eye on that sky, because what starts as rain up on the mountain road can be four inches by the time it reaches the streets below. The work is plowing, shoveling and de-icing: lots opened, walkways cut down to bare pavement, entrances scraped so nobody has to guess where the step is. The cold hours after a storm are their own job, when meltwater runs back across the concrete and turns hard again overnight. Winter here is short-tempered, and the answer is going out early and coming back.
