On a June afternoon the riverfront side of Brewer fills with light off the water and the grass grows nearly as fast as you can cut it. D B M Properties LLC keeps lawns mowed, trimmed and edged around the city's properties, with cleanups in spring and again when the leaves come down. A tenant walking up to a crisply cut lawn reads it before they read anything else: somebody looks after this place. Curbs edged, corners trimmed, clippings cleared, week after week without anyone having to ask. Across the water Bangor glitters, but the ground on this side is what gets kept.
