## Government
### Local government

Manville is governed under the borough form of New Jersey municipal government, which is used in 218 municipalities (of the 564) statewide, making it the most common form of government in New Jersey. The governing body is comprised of a mayor and a borough council, with all positions elected at-large on a partisan basis as part of the November general election. A mayor is elected directly by the voters to a four-year term of office. The borough council includes six members elected to serve three-year terms on a staggered basis, with two seats coming up for election each year in a three-year cycle.
The borough form of government used by Manville is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie. The mayor can veto ordinances subject to an override by a two-thirds majority vote of the council. The mayor makes committee and liaison assignments for council members, and most appointments are made by the mayor with the advice and consent of the council.
As of 2024, the mayor of Manville is Independent Richard M. Onderko, whose term of office ends December 31, 2027. Mayor Onderko earned a third term on November 7, 2023, holding off two challengers, making him the first mayoral incumbent elected without a party endorsement. Members of the Manville Borough Council are Council President Ron Skirkanish (R, 2025), Branden Agans (R, 2024), Dayna A. Camacho (I, 2026), Joe DiVeto III (R, 2025), Barbara Madak (R, 2024), Jade Nicolle Puia (I, 2026).
Preceding Mayor Onderko was Mayor Angelo Corradino, the only five-term mayor in Manville's history, the first Manville Mayor to be elected as the president of the New Jersey Conference of Mayors and the first mayor of Manville to be elected into the New Jersey Mayors Hall of Fame.

## Redevelopment

The Federal Superfund project called The Federal Creosote Site was cleaned up by the United States Environmental Protection Agency (EPA) with $250 million of public funds. The Superfund cleanup project was performed in a 35-acre (140,000 m$^2$) residential section of town called Claremont Development and in a 15-acre (61,000 m$^2$) commercial area called the Rustic Mall, and was officially declared complete by the EPA on March 7, 2008.

## Flooding problems

Manville suffers from occasional flooding events that occur after prolonged heavy rainfall events, when the Raritan River and Millstone River overflow their banks into the northern section (Raritan) and the Lost Valley section (Millstone) of the borough. The southern parts of Main Street also suffer from the flooding, due to the presence of Royce Brook which backs up with water from the nearby Millstone River in which it empties.
There are studies being undertaken to address the flooding problems in the Millstone River basin and Manville; however, none of the flood control ideas in the Millstone River basin have gotten beyond the initial study stages as of late 2006.

### Hurricane Floyd flood of 1999

Manville was severely hit by a flood in the wake of Hurricane Floyd in September 1999, which dropped 10 to 12 inches (250 to 300 mm) of rain in the areas surrounding the borough. The floods devastated the Lost Valley section, some of the South side area along Main Street and a large portion of the North side. Water levels reached between 12 feet (3.7 m) and 17 feet (5.2 m) in parts of the borough on September 17, 1999. The only way residents could get help was by boat or helicopter. There was also a large amount of fuel oil floating on the flood water which further damaged homes, many of which came off their foundations.
A portion of the north side received water coming from the Raritan at Dukes Parkway. Much of the north side had no flooding, though the significant flooding of the northside was concentrated from Dukes Parkway to Louis Street and Main Street to 3rd Avenue. The water reached the freight tracks at Main Street, and spilled over, flooding some on the South Street side, but leaving tons of water dammed in on the North Street side, where people had to be rescued from rooftops, or second floor windows and landings, by boat.
The problem was doubled in the Lost Valley section, as flood waters backed up where the Raritan and Millstone rivers meet near the dam. All trapped and injured people had to be taken out by helicopter, as there was no way to get in or out of the Lost Valley section. The September 1999 flood disaster was the worst ever to hit Manville, although it had been flooded in 1971 during Tropical Storm Doria, when many of the Lost Valley houses were destroyed and their foundations lost, and previously before that in the 1950s. Because of the railroad tracks being so much higher than the Lost Valley land, Manville's Lost Valley will always be a number one target for flooding. Through research of Manville's history, Lost Valley was to remain open land due to the high risk of flood.

### Lost Valley flooding

Manville is where the Raritan River and the tributary Millstone River join together, in the far northeastern corner of the borough. The Lost Valley section in eastern Manville is situated on the natural flood plain between the Raritan and Millstone Rivers and bears the brunt of occasional flooding events which affect the river basins. The Lost Valley section is named so because it is generally disconnected from the rest of the borough with only a tunnel at Kyle Street and a bridge at Bridge Street crossing the railroad tracks to the neighborhood. Hurricane Floyd in September 1999 produced a particularly severe flood (a record for the river basins) in Manville, especially in the Lost Valley section of the borough, which experienced flooding all the way to the railroad tracks, with twelve feet or more water on many properties, which inundated houses with damaging flood waters. Another severe and devastating flood event occurred in Lost Valley during the April 2007 Nor'easter. It also left many homes and businesses underwater and was the worst flood since Hurricane Floyd. Flooding problems once again occurred in Manville on March 14, 2010, with rivers running already high due to recent snow melt along with 3 to 4 inches (76 to 102 mm) of rain that fell on the area on March 13, flooding was inevitable. More extensive flooding affected Manville in August 2011 when Hurricane Irene passed through New Jersey. In the aftermath of Hurricane Sandy in late October 2012, Manville did not flood but the powerful winds left many homes without power for several days.

### Hurricane Ida floods

On September 1, 2021, the tropical remains of Hurricane Ida swept through Manville, causing floods in the majority of the town. The nearby Raritan river was flooded to a record 27.66 feet (8.43 m), shattering the previous 27.1 feet recorded by Hurricane Floyd. On September 2, 2021, a house on Boesel Avenue exploded after the residents of the home had already evacuated, and nearby on North Second Avenue, another exploded and engulfed a home next to it, burning down as firefighters were unable to access the home due to the heavy floodwaters. That night, a local banquet hall, The Saffron, exploded and burned to the ground early Friday morning.

### Flood gauge on Raritan River

Flooding occurs at a 14-foot (4.3 m) stage, and severe flooding occurs when the water reaches 18 feet (5.5 m). The National Oceanic and Atmospheric Administration provides access to real time river level data.
