Hampton Falls, Sanborn Rd Box Culvert

Sanborn Road, Hampton Falls, NH


Subject to frequent flooding from the Taylor River, Sanborn Road in Hampton Falls, NH was a continual maintenance concern and a potential detriment to public safety.  As the Town Engineer, Jones & Beach Engineers, Inc. (JBE) designed, permitted, and inspected a complete replacement of the existing concrete and stone box culvert.  The cross culvert was upgraded with a new precast structure; the crossing also featured three additional culverts to provide additional discharge capacity above bank full elevation.  With the placement of new granite retaining walls, the vertical alignment was raised out of the floodplain and a dry hydrant installed to service the surrounding neighborhood’s fire protection needs. Together, these improvements reduced flooding so significantly that the characteristically inundated crossing was not overtopped during the epic “Mother’s Day Storm” that overwhelmed southeastern New Hampshire in the spring of 2006.
