NHSA H-5 newsletter header

Message from the North Hudson Sewerage Authority

The North Hudson Sewerage Authority (NHSA) and the City of Hoboken are embarking upon a major infrastructure initiative to significantly mitigate severe wet weather flooding in the City’s northwest neighborhoods: the construction of the H-5 Wet Weather Pump Station (WWPS). In order to provide information and updates about the construction, we will be periodically circulating our e-newsletter, Turning the Tide, to the Maxwell community and other interested parties.

The e-newsletter will feature regular construction updates and previews of coming work at the site. It will include an update on the activities of the Licensed Site Remediation Professional (LSRP), who will oversee the Remedial Action Plan filed with the NJ Department of Environmental Protection (NJDEP). The newsletter will also provide the latest sidewalk and automobile access information, as well as updates on the air monitoring activities. Apart from the e-newsletter, we will have an on-site Resident Engineer and a 24/7 hotline.

This $11.4 million dollar project will provide significant public health and environmental benefits by minimizing the surcharging of CSO flows onto the City’s northwestern streets during high-tide, severe rain storm events. It will also protect from flooding the electrical substation that powers the Maxwell community and its neighbors, and it is an integral part of the City’s overall flood defense strategy in the event of another Sandy-type storm.

We understand that a project of this magnitude will bring with it some neighborhood disruption. We will do our best to minimize that inconvenience. Thank you for your patience, as we move forward.

Executive Director


Pre-construction update

After meeting with the Maxwell Home Owners Association (HOA) on June 8th, pre-construction activities for the H-5 Wet Weather Pump Station project were initiated. Concurrently, the HOA and North Hudson reached agreement on an environmental indemnification agreement which will be fully executed in the coming week.


A pre-construction meeting was held on June 15th with the DEP to coordinate with the State financial aspects of the project and labor/wage rates. The traffic and access plan, as discussed with the HOA, will be presented to the Hoboken Police Department (HPD) in the next week. The HPD is likely to schedule a meeting to discuss and approve the plan by the first week of July.

Upcoming Activities and Construction Schedule

The project’s three phases are dictated by engineering and construction requirements and will occur in three areas along 11th Street, as seen in the figure above. The three phases are: 1) the installation of the emergency generator; 2) the construction of the control vault; and 3) the construction of the wet weather pump station.


On Monday, June 22nd, pre-construction survey photos will be taken to document the condition of the streets, curbs and building exteriors. The contractor will be accompanied by the Resident Engineer and Maxwell building management. The utility mark-outs (survey) will be undertaken over the next two weeks, also with building management involved. With the approval of the LSRP, soil samples will be taken in the week following utility mark-out by a small bore geo-probe from the back of a utility truck. This will determine the soils characterization prior to beginning site preparation for excavation. During the pre-construction period, the LSRP will develop environmental requirements for proceeding safely with construction. [See below, “Role of the LSRP”]  

The current schedule is as follows:

  • Pre-construction activities: now to mid-August.
  • Construction begins: Mid-August through December. This will include work on the installation of the emergency generator on North Hudson’s existing 11th Street pump station island between Hudson and Washington Streets; and beginning work on the control vault and new H-5 WWPS.
  • LSRP monitoring begins with construction and ends when the cap is restored.
  • Control vault construction continues until April 2016.
  • Pump station construction continues until August 2016.
  • Final completion and site restoration is scheduled for October 2016.

Future issues of Turning the Tide Access will provide updates on the various phases of construction as they begin and progress. Further information may be found on the website: www.nhudsonsa.com.


Role of the LSRP

The Licensed Site Remediation Professional (LSRP) serves an extremely important function in the construction of the H-5 WWPS. LSRP will oversee all environmental issues on the site, including the voluntary air monitoring that North Hudson is undertaking. In this capacity, the LSRP is responsible to the NJDEP for ensuring that all construction is done in accordance with the Remedial Action Plan filed with the State during the original development of Maxwell Place. The contractors will take no steps that impact the environment without the strict oversight of the LSRP. The LSRP will report on a regular basis to the NJDEP.

Because Maxwell Place was constructed on land that was remediated for soil and groundwater contamination, an NJDEP-approved engineered cap was placed within the development and along 11th Street. The construction of the WWPS will lift minimal parts of the cap in carefully defined areas, and the LSRP will develop a Data Collection Plan to strictly supervise and control all related construction activities. No construction that impacts the existing cap can be undertaken without the approval of the LSRP.

The LSRP will also supervise the gathering of air samples adjacent to the construction, as part of North Hudson’s voluntary air monitoring program. The LSRP will oversee the air quality data collection and provide advice before construction begins, during excavation and until the cap is replaced.

Air monitoring

Although the NJDEP does not require air monitoring for the H-5 WWPS project, North Hudson is voluntarily monitoring the air surrounding the construction site for dust and volatile organic compounds (VOCs). The LSRP will continuously monitor the air during excavation activities and until the original cap has been replaced. This is a relatively conservative approach, as it is designed to alert the construction team whenever dust is in excess of the LSRP monitoring plan. Readings that show elevated levels of dust or VOCs in the air will result in review and remedial action to abate the condition as approved by the LSRP.  Our e-newsletter will provide regular summaries of the air monitoring activities, and the website (nhudsonsa.com) will post daily readings.
