The scope of the project improvements is limited to the roadway from curb to curb. With the exception of corners and improved lighting, the project will not include replacement of sidewalks or street furniture.

UPTOWN: TYPICAL SECTION


DOWNTOWN: TYPICAL SECTION


WORK WILL INCLUDE:

Traffic Signals

Installation of 15 new traffic signals with pedestrian countdown timers, emergency pre-emption system, and optimized signal timing

ANTICIPATED START DATE:

Work on the fifteen (15) traffic signals will commence in the early Summer of 2017

ANTICIPATED END DATE:

The entire duration of signal work will extend through the Spring of 2018. However, per the contract, the first traffic signal shall become active by June 2017. It is anticipated that after the first signal is activated, that a new intersection of signals will go live approximately every three (3) weeks on average until all fifteen (15) signals are completed.

WHY THIS WORK IS BEING DONE:

The traffic signals on Washington Street are some of the oldest in the United States. In fact, the clustered signal at 1st and Washington is believed to be one of the oldest continuously operating working traffic light in the United States. The signal heads were manufactured by the Horni traffic signal corporation that was one of the largest suppliers to the City of New York and also Northern NJ. It is believed that they date to the late 1920’s or early 1930’s. Since these signals are part of Hoboken’s history, two of the oldest will be donated and relocated to the Hoboken Historical Museum.

Due to the age of the current signals, they do not have modern technology such as LED lighting in the fixtures, pedestrian push buttons and count down heads, or emergency vehicle pre-emption. Therefore, the new traffic lights will have all of these modern amenities.

HOW IT WILL BE PERFORMED:

Temporary signals may be installed to safely navigate traffic through the intersection during construction. This will be followed by the electrical underground work. Then followed by the placement of above ground signals, then activation of the new signals, and lastly the removal of the old signals.

Curb Extensions

Installation of concrete sidewalk bump outs at corners

ANTICIPATED START DATE:

Work on the concrete bump-outs at intersections will commence in late Spring of 2017.

ANTICIPATED END DATE:

The entire duration of the concrete curb extensions will extend through the Spring of 2018. However, this work will occur within each work zone and be completed on average within two (2) weeks per work zone once concrete work commences in that work zone. Additionally this work will be isolated to the corners, so the effect to the remainder of the block is minimal.

WHY THIS WORK IS BEING DONE:

Based on crash data analyzed for the project from 2010-2013, there were 17 vehicular-pedestrian collisions on Washington Street. A large fraction of collisions occurred during vehicular turning movements. Curb bump outs at intersections improve visibility and shorten the crossing distance for pedestrians crossing within cross-walks on Washington. This creates a safer environment and minimizes conflicts with pedestrians and traffic.

HOW IT WILL BE PERFORMED:

The curb bump out work will be formed and poured at each intersection. Prior to the forms being placed, the contractor would remove the asphalt to approximately two (2) feet in front of the curb so that the forms can be placed to the proper curb depth. The concrete is then poured in the forms. After the concrete cures and the forms are removed, the Contractor will pave the trench in front of the curb.

Roadway Resurfacing & Pavement Markings

Base repair, milling, and resurfacing from Observer Highway to 15th Street. The addition of high visibility crosswalks, dedicated commercial loading zones, and bike lanes from Observer to 8th Street. All pavement markings will occur immediately following paving activities.

ANTICIPATED START DATE:

The base repairs on Washington Street will commence first and coincide with other work occurring in each work zone that requires trench repair. The full curb to curb milling and repaving of Washington Street is expected to commence mid Fall 2017 from Observer Highway to 8th Street and Spring 2018 from 8th Street to 15th Street.

ANTICIPATED END DATE:

The full curb to curb milling and repaving of Washington is expected to end in the Fall 2017 from Observer Highway to 8th Street and will be followed by all pavement markings that are expected to be completed by December 18, 2017. From 8th Street to 15th Street, paving will be completed by late Spring 2018. This will be immediately followed by all pavement markings which will be completed by June 20, 2018.

WHY THIS WORK IS BEING DONE:

The existing pavement on Washington Street is in disrepair. Repaving will allow for an even travel surface and will facilitate better surface drainage flow. Additionally, the milling and repaving will result in a fresh paved surface free of joints from multiple trenches that will result from the utility cuts for the micro-grid, water main, water services, drainage, and underground electrical for traffic signals.

HOW IT WILL BE PERFORMED:

Base repairs and trench repairs will occur first within work zones. Once all underground work is completed, then the roadway will be milled and repaved. It is likely that one side of Washington Street will be milled and repaved at a time to facilitate two-way traffic. Additionally, Washington Street will be milled and paved in two sections: Observer Highway to 8th Street and 8th Street to 15th Street. Once the repaving is completed in each section, it will be followed by high visibility striping, pavement markings, and colored markings.

Water Main Replacement

Replacement of century-old water mains and service lines to new valve boxes at the curb

ANTICIPATED START DATE:

The Water Main work will commence in March and April 2017. It will start with the installation of insertion valves for the entire length of Washington. This will be followed by the installation of a new water main, then replacement of service connections to the curb box. Hydrants will occur concurrently in each work zone with the service connections.

ANTICIPATED END DATE:

The entire duration of the Water Main work will extend through late Summer 2017, however, this work will be completed within each work zone within a matter of 3 weeks per zone on average.

WHY THIS WORK IS BEING DONE:

The Water Mains on Washington Street are a century old. As a result of the age of the lines throughout the City, there have been multiple water main breaks in recent months. Since the mains are old and the use of heavy construction equipment over the old mains increases the likelihood of a break, we are installing new insertion valves throughout Washington Street. This will enable the Contractor and SUEZ to isolate a block upon the occurrence of a break.
The water services are being upgraded and curb boxes installed for each connection to avoid future trenching of the new roadway and to ensure that all water services within the cartway (curb to curb) are new for the entire length of Washington Street. This will also decrease the number of incidents with the water main on Washington Street in the future, as individual property owners will only own up to the curb box. This will minimize the times that a property would need to tap into the mains on Washington.

The project will not include replacement of private service lines from the curb to buildings, so it is recommended that property owners who still have older lead water lines replace the service line to their property with copper pipe or other approved material. Please contact SUEZ Water at 844-341-5323 (LEAD) if you plan to replace your service line or visit www.mysuezwater.com/lead for more information.

Lastly, the hydrants on Washington are being upgraded to meet recommended separation distances.

HOW IT WILL BE PERFORMED:

Work will commence on the West side of Washington Street first on the 12” Main and then move onto the three (3) sections of 8” main on the East side of Washington. The Contractor may choose to work on both mains concurrently, provided he meets all work zone separations required by the Contract. Once a section of Water Main is completed, the Contractor will pressure test, chlorinate, and flush the line. In each work zone, once new water service connections and curb boxes are installed, then each old service connection is turned over to the new connection. This will result in a short disruption in service for each user, less than four (4) hours per connection typically. The Resident Engineer and/or his inspection staff will coordinate the timing of the disruption with the businesses and residents on each block to the best of their ability. Once the new service is completed, the old service will be abandoned and in most cases removed.

Green Infrastructure

The addition of 15 rain gardens and drainage improvements to capture stormwater and help reduce the impacts of flooding in the City

ANTICIPATED START DATE:

The rain garden installation on Washington is expected to commence in the Summer of 2017.

ANTICIPATED END DATE:

The rain garden completion will not occur until the Spring of 2018 due to the planting times.

WHY THIS WORK IS BEING DONE:

During extreme wet weather events, such as heavy rain, the combined sewer system sometimes hits its capacity and flooding occurs in the City. Additionally, if these events coincide with high tide, then the flooding is exasperated. The fifteen (15) rain gardens along Washington are designed to capture approximately 150,000 gallons of stormwater. This will reduce the amount of runoff making its way to the combined sewer system in the City, thereby reducing flooding.

HOW IT WILL BE PERFORMED:

Rain Gardens are in the vicinity of inlets near the intersection that are designed with overflow piping to allow runoff to enter and exit the rain gardens. The soil surface of the rain gardens are set several inches below the curb so that flow can be retained in the rain garden. The rain gardens are designed to then drain the runoff once it flows through the plantings to the appropriate level, and not to have the rain gardens pool stormwater. The rain gardens are planted with water tolerant species and areas of river stone to prevent erosion. The rain gardens are each equipped with decorative up lighting and have an area facility for long-term monitoring equipment. The purpose of monitoring a rain garden is to verify that it is functioning as designed, to inform the public of their benefits, and for the general purpose of public education and research on the benefits of Green Stormwater Infrastructure.

ADA Compliant Curb Ramps

Upgraded ADA handicap curb ramps at each intersection and at each new ADA parking stall installed on the project.

ANTICIPATED START DATE:

The ADA Curb Ramp installation on Washington Street is expected to commence in the late Spring/early Summer.

ANTICIPATED END DATE:

The ADA Curb Ramp completion will not occur until the Spring of 2018. However, this work will be completed intersection by intersection coinciding with the completion of the sidewalk curb extensions and signals at each intersection.

WHY THIS WORK IS BEING DONE:

Due to the installation of curb bump-outs, many ADA curb ramps are being relocated to the shortened crossing distance. Additionally, it is a goal of the City that the sidewalks be safe and accessible to all users.

HOW IT WILL BE PERFORMED:

The ADA ramps will be installed in accordance with all Federal Regulations and Guidelines. The sidewalk portion is formed, poured, and protected until it cures. Each ramp has landings outside of sloped areas and receives an ADA Compliant detectable warning surface that triggers those with vision impairment that they have left the roadway and have entered a safe area. It also acts as a slip resistant surface. While construction work is occurring on the ADA ramps, a safe and accessible route will be provided for pedestrians.

Lighting

Refurbishment of all existing street lights with more efficient lighting fixtures

ANTICIPATED START DATE:

The refurbishment of the existing street lights is expected to commence in the late Spring/early Summer of 2017.

ANTICIPATED END DATE:

The refurbishment of the existing street lights will end in the Spring of 2018.

WHY THIS WORK IS BEING DONE:

The street lights along Washington Street are dim and do not currently have energy efficient fixtures which are offered by PSE&G. The new LED fixtures will be brighter, have a whiter lighting effect, and be more cost effective and energy efficient. Better lighting levels assist with visibility along the sidewalks and the street.

HOW IT WILL BE PERFORMED:

The existing street lights will be re-painted with black paint by the Contractor, and PSE&G will replace all the lighting fixtures for the City. There will be coordination between the Contractor and PSE&G to accomplish this work.

Microgrid

Installation of conduit for a future electrical microgrid and fiber optic cabling

ANTICIPATED START DATE:

The installation of the microgrid is expected to commence in the early Summer of 2017.

ANTICIPATED END DATE:

The installation of the microgrid will end in late Spring 2018.

WHY THIS WORK IS BEING DONE:

When there is a mass power-outage caused by an emergency, catastrophe, and/or an extreme weather event, that is the time when the City’s Critical Facilities are the most vital. A microgrid allows critical facilities to share power and communication facilities by connecting the facilities underground through a series of conduits. This microgrid being placed in Washington Street is just the backbone system, that is sized to connect the critical facilities along Washington Street in the future. The City made the decision to install the microgrid now so that the new roadway would not need to be trenched in the future for its installation.

HOW IT WILL BE PERFORMED:

The microgrid will be installed by trenching in the roadway and installing a series of conduits and manholes for the length of Washington.
