Green Brook Flood Control Project

The Green Brook Flood Control Project is a flood control project in Somerset County in central New Jersey first proposed in the early 1970s in the wake of two major flooding events: a 1971 flood event and a major 1973 flood which ravaged the Green Brook and Raritan River basins, causing millions in property damage and several deaths in central New Jersey.

The worst flooding in the Green Brook basin occurs in Bound Brook, which partially lies on a natural flood plain of the Raritan River at the junction of the Green Brook and Raritan River.

To address this flooding problem, the United States Army Corps of Engineers has proposed the Green Brook Sub Basin Flood Control Project, which entails numerous flood walls, levees, channel diversions, widening projects and retention basins throughout the Green Brook basin.

The Green Brook Flood Control project has languished for decades due to a lack of federal funding. Hurricane Floyd in 1999 caused yet more property damage and deaths in the Green Brook basin, especially in Bound Brook, and reinvigorated the flood control project. As of 2006, two levees have been built on the western and eastern sides of Bound Brook. An important levee (R2) on the southwestern side of Bound Brook, which would prevent the Raritan River from flooding the downtown and nearby residential areas, has been completed. Full 150 year protection of downtown and nearby residential areas of Bound Brook is effectively in place with final construction due to be completed by the summer of 2014.

The April Nor'easter of 2007 flooded Bound Brook with the second highest crest ever recorded in the area, as the envisioned flood protection systems were not yet fully in place. However, the April 2007 flooding did reinvigorate efforts to complete the flood levee protection system around Bound Brook, to protect it from future flooding.

Flooding of downtown occurred in August 2011 when Hurricane Irene passed along the East Coast.
