History

Etymology

Established in 1857 as the last county created in New Jersey, it was named after the Union threatened by slavery dispute during this period, which would erupt into civil war in 1861.

History

All of present-day Union County was part of the Elizabethtown Tract, which was purchased in 1664, by English colonists from the Lenape Native Americans that lived in the area of present-day Elizabeth, New Jersey. Union County was formed on March 19, 1857, from portions of Essex County; it was the last of New Jersey's 21 counties to be established.

Many historic places and structures are to be found in the county, including on the National Register of Historic Places listings in Union County, New Jersey.

In the fall, Union County holds its annual "Four Centuries in a Weekend" festival for the public, celebrating and touring historic buildings, museums and sites in the county.

Geography

According to the U.S. Census Bureau, as of the 2020 Census, the county had a total area of 105.41 square miles (273.0 km²), of which 102.77 square miles (266.2 km²) was land (97.5%) and 2.64 square miles (6.8 km²) was water (2.5%).

Much of Union County is relatively flat and low-lying. Only in the northwestern corner does any significant relief appear as the Watchung Mountains cross the county. It is there that highest elevations, two areas approximately 560 feet (170 m) above sea level, are found in Berkeley Heights. The lowest elevation is sea level along the eastern shore at the Arthur Kill.

Notable events in county government

In 2023, Union County agreed to honor the site in North Jersey of what local activists described as the public execution by burning at the stake of three enslaved New Jerseyans in 1741. In 2023, the county worked to revise its logo, which has had what has been described as the only county seal in the nation that depicts a woman being shot, the murder of Elizabethtown's Hannah Caldwell by British soldiers during the American Revolutionary War. In 2023, Union County moved to revise its county seal, asking residents to participate in an online poll to choose between two alternatives, both of which eliminate the depiction of the murder.

Sheriff's Office

The Union County Sheriff's Office is located in Elizabeth, New Jersey.

It is currently headed by Peter Corvelli.

It was headed by Ralph Froehlich, a Union resident who was first elected in 1977 and served in office for 37 years, making him the longest-serving Sheriff in New Jersey history. There are two top deputies, known as undersheriffs, and they are Dennis Burke and Amilcar Colon. A 1981 investigation of the Union County Jail reviewed issues relating to overcrowding, escapes, and escape attempts in the detention facility.

On July 1, 2021, the Sheriff's Office regained control of the Union County Jail and made it a division within the organization; the Division of Corrections.

The New Jersey State Policemen's Benevolent Association Local 108 is the official labor union and the collective bargaining agent for the Sheriff's Officers of Union County. This body is subdivided into Local 108 for the line officers and Local 108A for the supervisors (sergeants, lieutenants, & captains).

Union County is the only county with a county police department. The Union County Police Department operates independently of the Sheriff's office. The Union County Police Department originally began as the Union County Park Police. The Union County Police are tasked with patrolling Union County's properties. They also supplement the local municipalities with police presence and patrol when requested. Martin Mogensen has been the Chief of Police since February 2023.

The Union County Police have several divisions and are relied upon for their multiple services. Currently assigned are Patrol, Detective Bureau, Emergency Services Unit, and the Marine Unit. Union County Regional 911 and Dispatch is one of the many services that the County Police provide. They are the primary PSAP for multiple municipalities, provide police/fire/EMS dispatch, dispatch medics, and Union County Fire Mutual Aid. The PD belongs to the New Jersey State Policemen's Benevolent Association, Local 73.

Public transportation

Passenger rail service is provide by NJ Transit via the Northeast Corridor, North Jersey Coast Line, Raritan Valley Line, the Morristown Line and the Gladstone Branch. Freight service is provided by on Conrail's Lehigh Line and Chemical Coast Branch. Freight and passenger rail service was provided by the Rahway Valley Railroad from 1897 until 1992 when the short line closed due to lack of customers.

NJ Transit provides bus service to the Port Authority Bus Terminal in Midtown Manhattan, as well as service to major cities in New Jersey and within Union County.

The Port Newark-Elizabeth Marine Terminal is part of the Port Authority of New York and New Jersey.

The southern portion of Newark Liberty International Airport is located in Elizabeth, within Union County.

Potential rail-to-trails

Union County Park Line rail trail is a proposed walking and/or biking trail proposed on old railroad tracks. Two abandoned rails exist in the county.

The City of Summit and the Summit Park Line Foundation are working on turning the line from Morris Avenue to Briant Park in Summit into a rail trail that will be approximately one mile long. This rail trail, potentially called the Summit Park Line, could provide a greenway to connect several county parks, akin to a Summit High Line. A path could run directly from Summit to the Arthur Kill in Linden, New Jersey on the Rahway Valley Railroad and the Staten Island Rapid Transit line.

The Summit city council applied for a $1 million grant toward the Summit Park Line project in November 2016. "If Summit is able to complete the project, it might help other parts of the greenway come through," said Union County Public Relations Coordinator, Sebastian Delia.

The Rahway Valley Railroad runs from Summit to Roselle Park. Beginning in Hidden Valley Park, the railroad right-of-way continues by connecting Houdaille Quarry, Briant Park, Meisel Park, Rahway River Parkway, Galloping Hill Golf Course and Black Brook Park. The ending of the railway is on Westfield Avenue in Roselle Park. The Staten Island Rapid Transit runs from Cranford to Staten Island, although the project would only include the section that runs from Cranford to Linden. The possible inception in Cranford would be a lot on South Avenue East. The ending of this trail would be in Linden at an empty lot. A boardwalk would run over the existing tracks to ease line reactivation.

Hawk Rise Sanctuary is a 95-acre ecological preserve and wetland complex in Linden in an area previously concealed by various industrial land uses. Its trails were created adjacent to the former Linden Landfill area by the New Jersey Department of Environmental Protection, the city of Linden and the New Jersey Audubon Society. The trails in the Hawk Rise forest are boardwalk, with some continuing as gravel along the edge of the former Linden Landfill. It has an overlook area where hikers can view the Rahway River and nearby marshes. It has been open to the public since 2012. The site includes diverse environments: forested wetlands, vernal pools, grasslands, shrublands, salt marsh, mudflats, a pond, and the tidal Rahway River. 163 bird species have been spotted there. It has been reported as vandalized.

Rahway River Parkway

The Rahway River Parkway is a greenway of parkland that hugs the Rahway River and its tributaries, such as Nomahegan Brook. It was the inaugural project of the Union County Parks Commission designed in the 1920s by the Olmsted Brothers firm, who were the sons of landscape architect Frederick Law Olmsted. Several county and municipal parks run along the Rahway River.

Elizabeth River Parkway

The Elizabeth River Parkway is a greenway of parkland alongside the Elizabeth River and its tributaries. It runs through Kean University and Liberty Hall Museum on the river's way to the Arthur Kill. The Elizabeth River Parkway is broken down into separate sections.

• Chatfield/Zimmerman - Hillside and Union Township
• Lightning Brook - Hillside and Union
•

Public golf courses

Union County's Division of Golf Operations runs two golf courses, which offer golf lessons and practice areas.

• Ash Brook Golf Course in Scotch Plains.
• Galloping Hill Golf Course and Golf Learning Center in Kenilworth. The facility, which hosts the headquarters of the New Jersey State Golf Association, hosted the 2016 New Jersey State Open golf tournament, the first public golf course to host the tournament since it was established in 1921.

Another notable course

• Shady Rest Country Club in Scotch Plains is recognized as the first African-American owned and operated golf clubhouse in the United States. As such, Shady Rest is the home course of the first African-American golf professional to play in the U.S. Open, John Matthew Shippen, Jr. (1879-1968), who is considered a pioneer of the sport. Originally a private club and center for African-American social life, the township acquired and renamed it in the 1930s as the 'Scotch Hills Country Club' and made it open to the public. The history and significance of the course and clubhouse has not always been promoted as a place of national historic interest. Thankfully, the National Park Service has listed the Shady Rest Golf and Country Club (_100007869) in the National Registry of Historic Places, in large part due to the efforts of the Preserve Shady Rest Committee. The committee continues working to further solidify Shady Rest as a local, state, and national landmark given its historical significance.
