Hurricane and Storm Damage Reduction Project, Port Monmouth, NJ, Phase II-Contract 3
A replenished coastline combined with a variety of flood-control measures will reduce risk of flooding and damage from coastal storms.
In June 2014, the district began the first phase of an extensive $110 million hurricane and storm damage risk reduction project along the shores of Raritan and Sandy Hook Bay in Port Monmouth, N.J., providing coastal-storm risk reduction for low-lying residential and commercial structures. Hit hard by Hurricane Sandy in 2012, with more than 700 structures damaged, problems had been escalating due to shoreline erosion and increased urbanization and development in an area with wetlands and creeks.
“The Army Corps of Engineers is pleased to provide this project for residents of Port Monmouth and the greater Middletown Township, home to nearly 66,000 people,” said program manager David Gentile. “A replenished coastline combined with a variety of flood-control measures will reduce risk of flooding and damage from coastal storms.”
As part of the Hurricane and Storm Reduction Project in Port Monmouth, KCC was awarded a firm-fixed price construction contract for the construction of:
- 2,225 linear feet of concrete floodwall (T-wall section)
- 415 linear feet of sheet pile spliced onto an existing bulkhead along the marina; and 23 linear feet of new sheet pile wall that ties into high ground
- 32-feet long by 7.8-feet high steel roller gate closure structure will be installed across Old Port Monmouth Road: The road closure gate work includes installation of electric winches, lighting, and signage. The floodwall and road closure gate will be supported on steel H-pile foundations and a sheetpile cutoff wall will extend beneath their base.
Additional project features include site grading, drainage swales with erosion control matting, storm water outlet pipes, manholes, armor rock, bedding stone, excavation and backfill of beach sand at dune tie-in, articulating cellular concrete blocks, utility relocations, sluice gate control chamber, road resurfacing, traffic control and signs, fencing, guide rails, vibration monitoring, planting and seeding, soil erosion and sediment control measures, removal of two existing osprey nesting structures and the installation of three new structures, site restoration, and liability insurance.
