Dover climbs as you walk away from the center, and the streets off Bergen tilt just enough that October leaves gather in long drifts against the curbs. Alberto Mendoza Landscaping LLC clears them, with leaf removal, fall and spring cleanups, mowing, edging and mulch through the growing months. In February those same slopes need salt and a careful pass with the plow so a car can get up to the door. The work is measured in small mercies: a walkway you can cross in shoes, a yard raked down to bare green before the first hard frost. Steady work on steady ground, and the borough keeps it interesting.
