The land rising from Plymouth Bay is considered to be the foothills to the Pine Hills.
The neighborhood of the same name runs along the shoreline from Route 3A just south of the merge with Plimoth Plantation Highway to the Pilgrim Nuclear Generating Station.
Heavy rains during July and August 2008 caused a failure of a storm drain on Rocky Hill Road east of Driftwood Lane.
The rainwater was diverted, forming a 6-foot-wide (1.8 m) gully along a property downhill on Driftwood Lane and washing out a stretch of that road.
The water also exposed the foundation of the house directly above that property on Rocky Hill Road.
