Loudon sits in Merrimack County on the southern edge of our range, forty-seven square miles of ridge, hayfield and river bottom between Concord and the Lakes Region. There is no municipal sewer anywhere in town and no public water either — all of the roughly 5,600 people here draw from a private well and send their wastewater to a private tank. Route 106 runs the length of the town past the New Hampshire Motor Speedway and down into the village, where it meets Route 129 at the Soucook River.
Loudon is really three settlements and a lot of countryside: the village along the Soucook, Loudon Center, and Pearls Corner, with farms strung along Loudon Ridge above them and forest and wetland filling in the rest. The town has been deliberate about staying that way — the 2018 master plan is largely an argument for keeping the farmland and the undeveloped river shoreline intact — and the practical result is big lots, long driveways, and no utility corridors to build density around. Most of the housing is postwar ranches and capes on two to five acres plus a stock of genuinely old farmhouses whose systems have been rebuilt in pieces over sixty years. A good share of the working population drives to Concord, which borders Loudon on the southwest, and comes home to a house where the water and the wastewater are both entirely their own problem. Then there’s the speedway, which for a handful of weekends a year puts more people inside the town line than live in it.
Loudon has almost no protected shoreland — a little frontage on Clough Pond, Rocky Pond and the Soucook, and that’s about it — so the RSA 485-A:39 site assessment that forces the issue in the lake towns almost never applies to a sale here. Nothing external is going to make you look at your system, which is the exact reason NHDES’s every-2–3-years recommendation belongs on a calendar instead of in the back of your head.
