New lawns and drainage

New lawns on new grade, and the drainage that goes under them when a yard holds water: filter fabric, crushed stone and infiltration chambers.

How we build it

Water that sits on a lawn or runs toward the house has to go somewhere. On the job in these photos, the excavation was lined with filter fabric, bedded in crushed stone and fitted with infiltration chambers, which hold the runoff and let it soak back into the ground.

Along porches and foundations, a bed of drainage stone does the same job on a smaller scale.

Then the yard is graded and brought back as a new lawn, often together with the walls, walks and plantings around it.

Questions

Where can a drywell go?

Under Title 5, at least 10 feet from the septic tank and 25 feet from the leaching field. A trench deeper than 3 feet also needs a trench permit from the town, even on private land.
