# Mahwah, New Jersey

Mahwah is the northernmost and largest municipality by geographic area (26.19 square miles (67.8 km$^2$)) in Bergen County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 25,487, a decrease of 403 (−1.6%) from the 2010 census count of 25,890, which in turn reflected an increase of 1,828 (+7.6%) from the 24,062 counted in the 2000 census. The name "Mahwah" is derived from the Lenape language word "mawewi" which means "Meeting Place" or "Place Where Paths Meet".
The area that is now Mahwah was originally formed as Hohokus Township on April 9, 1849, from portions of the former Franklin Township (now Wyckoff). While known as Hohokus Township, territory was taken to form Orvil Township (on January 1, 1886; remainder of township is now Waldwick), Allendale (November 10, 1894), Upper Saddle River (November 22, 1894), and Ramsey (March 10, 1908). On November 7, 1944, the area was incorporated by an act of the New Jersey Legislature as the Township of Mahwah, based on the results of a referendum held that day, replacing Hohokus Township. New Jersey Monthly magazine ranked Mahwah as its ninth best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.

## History

The Lenape and ancestral Indigenous peoples were the original inhabitants of Mahwah (the meeting place) and surrounding area.
In 1849, Hohokus Township was established from the northern part of Franklin Township in Bergen County. It extended from the Saddle River on the east to the western boundary of Bergen County with Passaic County and north to the New York border. Hohokus Township was first subdivided in 1886 with the creation of Orvil Township on both sides of the Saddle River, consisting of the eastern portion of Hohokus Township and the western portion of Washington Township. 1894's outbreak of "Boroughitis" brought the creation of the boroughs of Allendale and Upper Saddle River, both of which were created from portions of Hohokus and Orvil Townships. Next to leave was Ramsey, which was created in 1908.
Hohokus Township ceased to exist on November 7, 1944, when a referendum was passed creating Mahwah Township from the remaining portions of Hohokus Township.
For twenty-five years, beginning in 1976, Mahwah hosted the A&P Tennis Classic, a tune-up for the U.S. Open tennis tournament held at the USTA Billie Jean King National Tennis Center in New York City's Flushing Meadows–Corona Park.
The 75-room, three-story Crocker-McMillin Mansion, also known as Darlington, was built in 1901 for George Crocker, son of railroad magnate Charles Crocker. The estate, located at Crocker Mansion Drive, is one of New Jersey's historical landmarks.
Ford Motor Company operated the Mahwah Assembly plant from 1955, producing 6 million cars in the 25 years it operated before the last car rolled off the line on June 20, 1980. At the time of its completion, it was the largest motor vehicle assembly plant in the United States. The Ford plant, along with other businesses such as American Brake Shoe and Foundry Company, helped contribute to the economic development of the township and its reputation for low home property taxes. The Mahwah town sports teams remain named Thunderbirds in honor of the Ford plant.
Due to contractors' dumping of hazardous wastes at the Ringwood Mines landfill site before federal regulation, it has been designated as an EPA Superfund site which needs extensive environmental cleanup. In 2006, some 600 Ramapough Indians filed a mass tort claim against Ford for damages. Mahwah, and the closure of the Ford plant, is mentioned in the opening line of the 1982 Bruce Springsteen song "Johnny 99".
In July 2017, while holding the position of Bergen County prosecutor prior to becoming New Jersey Attorney General, Gurbir Grewal ordered the Mahwah police department not to enforce a ban on non-New Jersey residents using parks in Mahwah, stating his concern that a ban could lead to anti-Semitic religious profiling against the growing population of Orthodox Jews in Mahwah and those visiting from neighboring Rockland County, New York. On December 14, 2017, following the advice of legal counsel, the Mahwah council repealed the still-unenforced ban on out-of-state park users, and abandoned an attempt to amend the sign ordinance to bar "other matter" (the lechis) from being affixed to utility poles to form an Orthodox Jewish eruv.

## Government
### Local government

Mahwah is governed within the Faulkner Act (formally known as the Optional Municipal Charter Law) under the Mayor-Council system of municipal government (Plan B), implemented by direct petition as of July 1, 1984. The township is one of 71 municipalities (of the 564) statewide that use this form of government. The governing body is comprised of the Mayor and the seven-member Township Council, with all members elected at-large to staggered four-year terms of office on a non-partisan basis as part of the November general election in even-numbered years. Four council seats are up for vote together and then three seats and the mayoral seat are up for vote together two years later. The legislative powers of the township are exercised by the Township Council. In September 2010, the township council voted to shift the township's non-partisan elections from May to November, citing increased voter participation and prospective savings of $30,000 associated with supporting each election, with the first November election taking place in 2012.
As of 2023, the Mayor of Mahwah is Jim Wysocki, who was elected to succeed John Roth, and whose term of office ends December 31, 2028. Roth had been elected in November 2018 following the recall of the former mayor, William Laforet. Members of the Township Council are Council President Rob Ferguson (2026), Council Vice President Michelle Paz (2028), Janet Ariemma (2026), George Ervin (2028), Ward Donigian (2026), Dave May (2028) and Jonathan Wong (2026).
Then-Mayor Bill Laforet faced a recall election in November 2018, after a resident group submitted in June a list of 5,000 petition signatures that they had collected calling for the action, in excess of the 25% needed to place the measure in front of voters. In the November 2018 general election, Laforet was recalled from office and John Roth was elected mayor. The successful recall was the first in the county for at least 25 years.
Michelle Paz, a Republican, was appointed to fill the seat expiring in December 2020 that was vacated following the resignation of Steven Sbarra that became effective at the end of December 2017, and was elected in her own right in November 2018 to fill the unexpired term.
At the January 2017 reorganization meeting, David May was sworn in to fill the seat expiring in December 2020 that had been won by Jonathan Marcus in the November 2016 general election, but which Marcus decided not to accept; May was elected in his own right in the November 2017 general election, to serve the balance of the term.
In December 2016, the Township Council selected George Ervin to fill the seat that had been held by Mary Amoroso expiring in December 2018 that became vacant after she was elected the Bergen County Board of Chosen Freeholders; Ervin served on an interim basis until the November 2017 general election, when voters elected him in his own right to fill the balance of the term. Ervin was re-elected in the November 2018 election to fill a full four-year term, expiring in 2022.
In August 1997, due to personal debt, then-Mayor David J. Dwork shot and killed himself in the town's mayoral offices. There were also unverified allegations of corruption. Dwork was memorialized with a tree dedicated to him at the site of the Mahwah Public Library. Dwork was succeeded by Richard J. Martel, then a township council member, who served for 14 years until his own death, of natural causes, on March 7, 2011. Martel himself was succeeded by Council President John DaPuzzo as acting mayor.

## Education
### Public schools

The Mahwah Township Public Schools provides public education for students in pre-kindergarten through twelfth grade. As of the 2019–20 school year, the district, comprised of six schools, had an enrollment of 2,913 students and 262.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 11.1:1. Schools in the district, with 2019–20 enrollment data from the National Center for Education Statistics, are Lenape Meadows Elementary School with 328 students in grades Pre-K–3, Betsy Ross Elementary School with 241 students in grades K–3, George Washington Elementary School with 189 students in grades K–3, Joyce Kilmer Elementary School with 414 students in grades 4–5, Ramapo Ridge Middle School with 685 students in grades 6–8 and Mahwah High School with 900 students in grades 9–12.
The district's newest building, Lenape Meadows, was opened in 2002 and changed the way the district divided up grade levels. Since the K–3 grades are broken up by location in the township which determines the elementary school to attend, before Lenape Meadows was built, students of that section of town attended Commodore Perry School. Commodore Perry School, Betsy Ross, and George Washington originally only housed the K–2 grades and the entire 3rd grade class attended Joyce Kilmer. The construction of Lenape Meadows added enough room for 3rd grade students as well, allowing Betsy Ross and George Washington room to house their students for 3rd grade, too.
Public school students from the township, and all of Bergen County, are eligible to attend the secondary education programs offered by the Bergen County Technical Schools, which include the Bergen County Academies in Hackensack, and the Bergen Tech campus in Teterboro or Paramus.
