My new front lawn has sprouted some very interesting sink holes. Some of it may be attributed to the water table being high, and the fill settling into the places where the contractor buried a lot of rocks and tree stumps. But 2 of the new sink holes are in the upper lawn which has been stable for over 25 years, and all of the sink holes seem to be in a fairly straight line from the 2 upper ones to the one furthest away. One of them is bubbling quite regularly. The ditch is not helping matters. We never noticed until we had land cleared that the ditch drains across this newly seeded lawn. Before, the area was all wooded. We knew it was wet, but didn't pay much attention. Now the ground level has been raised up, and the ditch still drains across it. Will need to call the town office.
