Every delivery in Edgewater starts with the same question: top of the cliff, or bottom? The borough is a ribbon roughly four miles long and only a few blocks deep, pinned between the Hudson and the Palisades rock face, and one ZIP code — 07020 — covers all of it from the Fort Lee line down to North Bergen. River Road, County Route 505, is the single continuous street through the whole thing, and the one graded way out to the west is NJ Route 5, climbing to Palisades Park and Fort Lee. That climb is where birthday orders go sideways. A house number on Undercliff Avenue or Dempsey Avenue sits at the base of the rock, but the nearest road a mapping app can see is often the one on top of it in Cliffside Park, two hundred feet up and reachable only by coming back down to River Road. A runner who trusts a dropped pin instead of a street name spends twenty minutes above the address looking at its roof. Naming the cross street in the delivery note ends that problem in one line. The second thing to know is that Edgewater is two housing markets leaning against each other, and birthdays land in both. On the river side, the old industrial waterfront came back as gated complexes with staffed lobbies and package rooms — Independence Harbor, Avalon at Edgewater, the mid-rise blocks strung either side of the ferry landing, and the Edgewater Colony community at the south end, which is private and posted at the gate. Those are the clean handoffs: the desk signs for it, logs it and texts the resident. The cost of that convenience is a bouquet sitting behind a counter for six hours. Against the cliff, the older streets — Old River Road, Undercliff Avenue, Hilliard Avenue, Myrtle Avenue, Dempsey Avenue — are two-family houses and small walk-ups with a shared entry, a driveway wide enough for exactly one car, and a bell that may or may not still be wired. No lobby, no doorman, and nowhere to leave a box out of sight of River Road. Then there is the road itself, which carries everything the borough does: the supermarket and big-box curb cuts, the Mitsuwa Marketplace lot at 595 River Road, the ferry queue, the construction trucks and every resident of every tower. Whole Foods, Trader Joe's and Target sit within about a mile of one another on it. At the Route 5 light and again at those driveways, the late afternoon slows to a crawl, and a 1.4-mile run from Ridgefield can eat twenty-five minutes between four and six.
