Glacial Landforms and Andover Lawns
Hydroseeding in Andover runs into a lot of glacial geology. The town has many glacial features, including drumlins, eskers and glacial erratics, and those landforms decide how steep a lot is and what kind of soil is under it.
Drumlins versus eskers
A drumlin is a smooth hill of packed till; an esker is a long ridge of sand and gravel left by a stream under the ice. USDA notes that sand-and-gravel soils on eskers and kames, such as the Hinckley series, run from gentle to very steep slopes and drain excessively. On an esker lot, seed dries out fast and slopes ravel easily, so we add loam and use a heavy hydromulch or blanket. On drumlin till the soil holds water better but the subsoil is tight, so we watch for spots where water sits.
High ground
Holt Hill, in the Charles W. Ward Reservation, is the highest point in Essex County at 420 feet. Homes on its flanks and other hills in west Andover deal with longer slopes and faster runoff than those in town center.
Two rivers
The Shawsheen River runs through town, and the Merrimack forms half of the northern border. Lots that drain toward either river, or toward Fosters Pond and Pomps Pond, get silt fence or compost sock along the low side during work.
Drinking water
Haggetts Pond in west Andover is the town's reservoir, and since the late 1990s it has received water pumped from the Merrimack to meet demand. Keeping sediment out of the pond's watershed matters to the whole town, so we stabilize soil quickly on nearby jobs.
Open land
The Conservation Commission and the nonprofit AVIS together hold around 3,000 acres. Many yards border that land, and we keep seed and mulch off it.

Andover Questions
How can I tell if my lot sits on an esker?
A long, narrow ridge with sandy, gravelly soil is a good sign. We can tell when we dig a test hole during the estimate.
Why does my sandy slope keep washing out?
Loose sand moves easily once it is bare. A layer of loam plus a blanket or heavy hydromulch holds it until roots knit.
Do you need to know if I am near Haggetts Pond?
Yes. Jobs near the water supply get extra attention to sediment control.
Can you seed right up to conservation land?
We seed to your property line and keep spray and mulch off the conservation side.
