The town of Belville sought to create a Riverwalk along the Brunswick River using land deeded by the county. Phase 1 of the park project includes just under a mile of walking trails, 1,500 feet of boardwalk, a 200-foot-long fishing pier, a 130-foot bridge, an outdoor classroom and an observation pier. KCI was contracted by the town to provide structural design for the outdoor amenities.
With cost as a primary driver, our team was asked to determine how to build the boardwalk, piers, ramps and bridge as efficiently as possible. Details were developed that allowed for use of standard lumber lengths to reduce waste, speed construction and provide a uniform appearance throughout. KCI worked closely with the geotechnical engineer to develop a boring plan and design foundations that could be easily built with small equipment. Research was conducted to identify appropriate materials for the brackish waters and coastal environment. Various levels of wood treatment, fasteners and foundation types were incorporated into the design to reduce cost while ensuring the structures could withstand the harsh environment.
Engineers worked closely with the trail design firm during permitting. Because of its location on the Brunswick River, the site was very environmentally sensitive and required 404 permits as well as CAMA permits. A mix of foundation types were selected depending on where the structure was located on the site. For example, wet jetting piles were preferred to driving piles in many areas to prevent harm to spawning fish.
Belville had a grand vision for this property to become a park that the whole community could enjoy rather than a traditional development.

Structures were designed to ensure ADA compliance while achieving designed elevations along the uneven terrain. Even the fishing pier includes accessible stations that also increase aesthetics by breaking up the continuous rails.
With construction complete, the town commissioners are pleased with the results—citing that the Riverwalk enhances property values, improves lifestyles, and creates a more attractive area for businesses and tourism.
