Seventeen people per square mile spread across ninety-one square miles of land. That’s Sandwich, and it’s another way of saying the driveways here are long. The town has practice at this. Sandwich Notch Road was cut through in 1801 — about nine miles of it between here and Thornton — and better than two centuries later it is still dirt. A Sandwich driveway that lasts gets built the way that road survived: water first, grade second, surface last. Do it in the other order and you’ll be regrading every spring.
The Notch road is worth understanding because it’s the local baseline. Thirty or forty families lived up in there in the early 1800s with mills and schools and a tavern; by the early 1900s there was a single year-round resident left and the farms had gone back to woods. The road stayed. A conservation push in the seventies and eighties — Save the Notch — put essentially the whole length inside some form of protected land, which is why it is still a rough dirt road and not a paved shortcut to Waterville. Beede Falls and Sandwich Notch Park sit at the Sandwich end of it. The lesson in all of that is simple: a dirt road built for drainage outlasts a paved one built for speed.
Sandwich has its own numbers for this. A driveway has to be at least ten feet wide, a street access at least eighteen, and neither may exceed fifty feet where it meets the roadway. A driveway may serve no more than two lots — past that the town treats it as a road, which is a different standard entirely. You need 160 feet of frontage in Rural/Residential, 320 on water, and the principal structure sits seventy-five feet back from the road centerline. Whether the permit comes from the town, from NHDOT, or from both depends on what you’re coming off: Routes 25, 109, 113 and 113A are state highways and everything else is town or private. One more wrinkle worth knowing early — inside the Shoreland District there are limits on what you can surface a driveway or a parking area with, so on a lot near water the material is a permitting question, not a preference.
Two scheduling realities nobody mentions in a brochure. Mud season first: the working window runs roughly April through November and the opening weeks of it are the worst time of the year to put a loaded truck on a soft camp road. Second, the Sandwich Fair, which runs Columbus Day weekend on its own fairgrounds in Center Sandwich and brings something like thirty thousand people into a town of about fifteen hundred, most of them up Routes 109 and 113. Nobody should be scheduling a gravel delivery into the village that weekend, and we don’t. We also won’t take a loaded truck up a seasonal drive in late March because somebody’s in a hurry. Might cost us the job. That’s fine.
If your Sandwich drive washes every spring, don’t order stone yet. Walk it in a hard rain and find where water joins the drive and where it leaves. Nine times in ten the fix is a crown, a ditch and one pipe — not a new surface.
Crown and ditch, then everything else. A driveway is a long narrow roof — its job is to shed water sideways into something that carries it away. We cut a crown of roughly a half inch per foot, ditch both sides where the grade calls for it, and put cross-culverts in wherever water is already crossing the line. Skip that last part and the water picks its own crossing, which is usually straight through the middle of your drive in the first thaw.
On the hills, and most of this town is hills, the layout matters more than the material. Grade breaks and short flat landings keep water from running the entire length and taking the surface along with it. Turnouts go in where a truck has to pass or back up. The turnaround at the top gets sized for a fire truck rather than for your car, because the fire truck is the one vehicle you cannot carry up the hill yourself. Steep runs get coarser stone than flat ones; the fine stuff washes.
Base, then surface. On soft or wet ground, geotextile under the base earns its cost in one season by keeping the subgrade out of the stone. Bank-run gravel for the base, compacted in lifts, then three-quarter crushed on top for a surface that locks instead of rolling under a tire. Rebuilding an existing drive — re-crowning, re-ditching, adding the cross-culverts somebody skipped, topping with crushed — costs a fraction of new construction and fixes most of what people around here call a drainage problem.
New gravel driveways in Sandwich run $15–$30 per linear foot for a twelve-foot travel way with base, surface and crown. Long, gently graded runs sit toward the low end per foot; hillside drives with grade breaks, turnouts and cross-culverts land at the top. Regrading and re-crowning an existing drive costs a fraction of new. Culverts, headwalls, aprons and the permit meeting are quoted per site.
At least ten feet by ordinance, and no more than fifty feet where it meets the roadway. A street access has to be at least eighteen. A driveway may serve no more than two lots; serve a third and the town treats it as a road, which is a different standard. We build most residential drives twelve feet with turnouts.
Depends on the road. Routes 25, 109, 113 and 113A are state highways, so access off those goes through NHDOT, sometimes alongside town approval. Off a town road it’s the town. On a private or Class VI road it’s a different conversation again. We find out which applies before any design, because the answer can move the whole entrance.
Check the ordinance before you decide. Sandwich’s Shoreland District reaches 600 feet from several named lakes and ponds and it carries limits on driveway and parking surface materials, which makes the surface a permitting question rather than an aesthetic one. Pervious options exist, and on some lots they are the only options.
Almost always the crown, the ditches, or a missing cross-culvert, in roughly that order. Water runs the length of the drive instead of leaving it, picks up speed and carries the surface off. Re-crowning, re-ditching and putting a pipe where water already wants to cross fixes most of them for a fraction of a rebuild.
Roughly April through November, and we’re honest about the early end of it. Loaded trucks on a soft camp road in late March do more damage than the job is worth. We also stay out of the village on Sandwich Fair weekend, Columbus Day weekend, when thirty thousand people are coming up Routes 109 and 113.
