In Wakefield a fair amount of the ground you’re digging in is somebody’s drinking water. The town lays an Aquifer and Wellhead Conservation overlay across the stratified-drift deposits the USGS mapped and across every wellhead protection area, and that overlay has teeth. Blasting has to be planned so it doesn’t foul groundwater or pull down the neighbor’s well. Any inactive well on the lot has to be sealed before you disturb the first shovel of earth. We plan around it. Cheaper than being told to stop.
Stratified drift is sand and gravel, and sand and gravel is the best digging in town and the most fragile water in town at the same time. It takes a machine easily. It also takes whatever you spill straight down. The master plan is blunt about it — contaminants spread fast through permeable soil and can ruin an aquifer as a supply — and the ordinance follows through. In the overlay, road salt can’t be stored outdoors and salted snow can’t be dumped. Sand and gravel can’t be taken within ten feet of the seasonal high water table unless the Planning Board grants an exception under RSA 155-E:11. Any infiltration structure needs four feet of clean vertical separation over that same seasonal high water table, and a soil scientist or engineer has to be the one who says where it is.
The well rule is the one that surprises people, and it comes up constantly on old Wakefield camps. Before land-disturbing work starts, every inactive well on the property counts as abandoned and has to be sealed to the state Water Well Board standard. On a place that’s been in a family since the forties there is very often a stone-lined dug well behind the shed that nobody has thought about in thirty years, planked over and grown in. Finding it with a machine is a bad afternoon. We look for it on the walk-through — old depressions, a suspiciously flat spot, a pipe stub in the cellar going the wrong way.
Blasting gets its own line in the ordinance: it has to be planned and carried out to minimize groundwater contamination, and excavation generally has to avoid dewatering nearby drinking wells. That matters here because the other half of town isn’t gravel at all. The soils the master plan flags as poor for septic are limited by slope, by seasonal wetness, by slow percolation and by shallow depth to bedrock, and shallow depth to bedrock means exactly what it sounds like. On those lots the question isn’t whether there’s ledge, it’s how far down and whether we break it, hammer it, or move the house eight feet.
There’s a coverage ceiling too, and it changes what fits. Impervious surface generally can’t exceed 80 percent of buildable area; in the aquifer overlay it’s 50 percent, and in the protected shoreland zone it’s 30. Go past 15 percent impervious — or 2,500 square feet, whichever is larger — on an overlay lot and you need a conditional use permit with a real stormwater plan behind it. House, garage, drive and patio add up quicker than anybody expects.
If your Wakefield lot is on the mapped aquifer, add up the house, the garage, the drive and the patio before you draw anything. Crossing 15 percent impervious — or 2,500 square feet — turns a building permit into a conditional use permit with a stormwater plan attached.
Test pits first, always, and we’d rather dig three than guess once. They tell us the depth to ledge, the depth to seasonal high water, whether we’re in the gravel or the till, and whether the spoil is going to be reusable structural fill or a trucking bill. On an overlay lot that water-table number is the whole design: it sets how deep the footings can go and whether an infiltration system is even legal on that spot.
Then Dig Safe. Call 811 and wait the marks out, every time, and that goes for the private camp roads too, where buried service to a neighbor rarely runs where you’d expect. Foundation and utility trenching gets dug to frost, and frost in this part of the state runs four feet and more, so footings go below it and water line goes below it and nobody gets a call in February.
Season is April through November, give or take the year. We front-load foundations to spring and early summer so there’s time to backfill, grade and get cover established before the ground shuts. Late-fall digs are doable and we do them, but the stabilization plan has to be honest about what will and won’t grow in October. Spoil stays on plastic or on the pad, never stockpiled loose over gravel ground, and nothing with fluid in it parks over the aquifer overnight.
Machine and operator run $110–$200 an hour. Most Wakefield foundation digs land between $3,000 and $10,000 — the clean gravel lots sit at the bottom of that, and shallow-bedrock ground where we’re breaking ledge or working a tight camp access pushes the top. Test pits are how the range becomes one number.
It’s an overlay over the USGS stratified-drift aquifers plus every public wellhead protection area, and the town keeps the map in the zoning office as part of the official zoning map. If the boundary looks wrong on your parcel the ordinance lets you hire a hydrogeologist to pin it down and ask the Planning Board to adjust it.
Yes, and before the machine starts. The ordinance treats any well not in use or properly maintained as abandoned, and it has to be sealed to the Water Well Board standard prior to land-disturbing activity. It’s a short job when you find it first and an expensive one when a bucket finds it for you.
Depends where you are. The gravel side of town digs clean; the ground the soil survey flags for shallow depth to bedrock is a different story. Test pits answer it before you commit. Sometimes the cheapest fix isn’t breaking rock at all — it’s shifting the footprint a few feet or raising the slab and bringing in fill.
It can be done, with a licensed blaster and the ordinance’s conditions met — the work has to be planned to avoid contaminating groundwater or dewatering nearby drinking wells, which on overlay ground means a pre-blast well survey and monitoring. On smaller jobs a hydraulic hammer is often slower per yard but simpler to permit.
Roughly April through November. Frost runs past four feet in this part of the state, so winter digging means frozen spoil, poor compaction and no realistic way to stabilize bare ground. We’ll work late into the fall when the job calls for it, but we’d rather have the backfill graded and seeded before the ground closes.
