West Lawrence Pump Station Bank Stabilization Project

Description: The project generally consists of embankment stabilization improvements comprised of gabion baskets, gabion mattresses, loose stone riprap, and live staking. The improvements are intended to restabilize the eroded embankments, which are in close proximity to the pumping station. The tributary embankments have eroded to the extent that existing pavement and fencing have been damaged, and accordingly the project also proposes new chain link fencing, perimeter concrete flush curb, and pavement restoration beyond top of bank. It should be noted that the proposed edge of pavement will not extend beyond the existing edge of pavement, and the flush curb will maintain existing site drainage patterns. The pumping station is a critical facility for the Township, and accordingly the improvements are necessary scour countermeasures that are anticipated to repair existing damage within the site and mitigate future embankment erosion proximate to the site. As a result of Hurricane Ida, the West Lawrence site experience bank erosion along Sucker Brook, resulting in displacement and damage to the existing chain-link fence and undermining the damage to the existing asphalt pavement. The proposed improvements to the site are intended to stabilize the eroded streambank, restore the affected areas of the West Lawrence Pump Station site and address applicable permitting and regulatory requirements.
