Main Street separates two drainage directions
Moorestown's environmental inventory places Main Street on a ridge, with elevations exceeding 100 feet above sea level. It identifies that ridge as the divide between the Pompeston Creek/Swede Run watershed to the north and the Pennsauken Creek watershed to the south.
We use this as a starting point when discussing runoff, not as a promise that higher ground keeps a basement dry. At your house, we inspect the slope immediately beside the wall and look at where roof water lands. A local low spot against the foundation deserves attention even when the surrounding neighborhood sits uphill.
