Construction update

During the week of November 9th, the contractor began the installation of the reinforcing steel within the formwork for the walls of the pump station. Neighborhood residents have inquired as to the construction of the transition vault. In spring 2016, the excavation for the transition vault (see below diagrams) will begin. The transition vault, which is immediately adjacent to the pump station excavation, is separate from the control vault and the pump station. The first diagram below depicts the three (3) main below grade elements of the pumping station. These three elements are: 1) the weir, which allows the wet weather overflows to enter the pump station during storm events; 2) the pump station; and 3) the transition vault over the CSO outfall, which pumps wet weather flow back into the outfall during storm events. The second figure shows the location of the below ground transition vault at street level looking West on 11th Street.

Transition vault street level

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

Latest construction activity

During the week, construction submittals from the contractor continue to be reviewed and processed by NHSA engineers. The relocation and placement of the electrical ductbank within 11th Street was completed between the control vault and the 11th Street Pump Station. The contractor installed temporary asphalt pavement at the ductbanks and will mill and repave the area once the remaining work is completed in the spring of 2016. As indicated above, the contractor has completed the concrete for the control vault and the foundation slab of the pump station. The construction of the walls of the pump station are underway. The contractor is coordinating with PSE&G for approvals to continue preparatory work for the installation of the emergency generator at the NHSA island between Hudson and Washington Streets.

As of November 12th, a number of submittals have been approved or are close to approval. These are:

  • Removable handrails for the control vault
  • Stormwater pump column mounting and discharges
  • Heating and ventilating equipment
  • Electrical equipment
  • Valves for the mechanical process piping
  • Reinforcing steel for the pump station foundation
  • Storm drain relocation
  • Force main relocation
  • ┬áDust control plan
  • Process piping for pumping equipment
  • Reinforcing steel for transition vault
  • Reinforcing steel for pump station
  • Electrical wiring and grounding
  • Soil sampling plan for pump station
  • Waterproofing
  • Dewatering plan
  • Emergency generator

Coming up

In the next two (2) weeks, the contractor will continue to prepare submittals and obtain approvals for construction activities. Going forward into the week of November 16th, these activities will include:

  • The contractor will be placing the concrete in the formwork for the pump station walls. Once the walls have been placed the contractor will continue with the top slab formwork and reinforcing steel installation.
  • The contractor is coordinating the electrical service from PSE&G to continue electrical rough in and installation of equipment within the control vault.
  • The contractor will continue to have a water truck available to abate dust and soil an erosion controls to prevent the migration of dust from the construction area.
  • The Licensed Site Remediation Professional (LSRP) air monitoring program continues in place.

The following new submittals are being reviewed by NHSA engineers:

  • Stormwater pump columns and discharges
  • Removable handrail at the control vault
  • Heating and ventilating equipment
  • Electrical submittals
  • Process piping
  • Process valves and operators

LSPR update

The LSRP’s recent activities include:

  • Air monitoring of the site began on Thursday, August 27th and continues, in accordance with the LSRP-approved plan.
  • The air monitoring readings are continuing. Daily updates are being sent to the HOA and the weekly updates are being posted on the NHSA website.

Overall construction schedule

The current overall construction schedule remains as follows:

  • Pre-construction activities: Completed as scheduled.
  • Construction activities, now underway: Mid-August through December. This includes work on the installation of control vault and pump station. The emergency generator on North Hudson’s existing 11th Street pump station island between Hudson and Washington Streets will also be constructed once the transformer and generator are procured.
  • 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.

Role of the LSRP

The LSRP serves an extremely important function in the construction of the H-5 WWPS. He 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.


The recent air monitoring data can be found on the NHSA website.

Sidewalk and auto access

This is the most current information and will be updated going forward.



South sidewalk on 11th Street: Open at all times.

East sidewalk on Sinatra Drive North: Maintain drop-offs for school.

North sidewalk on 11th Street: Brief intervals of closure between Sinatra Drive North and Hudson Street.

East and West sidewalk at Maxwell Lane: Maintain access for drop-offs to daycare.




Uninterrupted access to parking garage.

Eastbound traffic lanes 11th Street: Short temporary closures during utility relocation; both lanes closed during pump station construction between Maxwell Lane and Sinatra Drive North. Open at all times from Maxwell Street to Hudson Street.

Westbound traffic lanes 11th Street: Temporary closures for traffic relocation between Maxwell Lane and Hudson Street. Both lanes closed during pump station construction from Maxwell Lane to Sinatra Drive North.




No street parking during construction hours between Maxwell Lane and Hudson Street.

No street parking on 11th Street from Hudson Street to Sinatra Drive North (Eastbound).


Effect on local businesses


Sidewalk access permits unimpeded foot traffic to local businesses.

Traffic controls at site will minimize business impact.

Drop-off point will be maintained during construction.

Parking access may have
limited effect.

Parking garage access remains in place.

Restrictions on street parking will be impacted during construction.

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.
