Down along the Mamaroneck line, where Beaver Swamp Brook threads its low green corridor, autumn shows itself early — a few maples going red, then the whole street at once. Peter Navarra Landscaping & Maintenance follows that turn from one kind of work into the other: mowing, trimming and leaf cleanups until the yards are bare, then plowing, shoveling and de-icing when the first hard night lands. Maintenance is the honest word for it, the same lawns and the same drives, week after week, kept the way people like to find them. There is pride in a lot raked down to the last leaf, and pride again three weeks later when that same lot is open before sunrise.
