# Chelsea, Massachusetts

Chelsea is a city in Suffolk County, Massachusetts, United States, sitting across the Mystic River from Boston. The 2020 census reported Chelsea as having a population of 40,787, thereby making it the second most densely populated city in Massachusetts. With a total area of 2.46 square miles (6.4 km$^2$), Chelsea is the smallest city in Massachusetts in terms of total area.

## History
### Prehistory

The area of Chelsea was first called Winnisimmet, possibly meaning "swamp hill", by the Naumkeag tribe, which had lived there for thousands of years.

### 17th and 18th centuries

Samuel Maverick became the first European to settle permanently in Winnisimmet in 1624. His palisaded trading post is considered the first permanent settlement by Boston Harbor. In 1635, Maverick sold all of Winnisimmet, except for his house and farm, to Richard Bellingham. The community remained part of Boston until it was incorporated in 1739. It was named after Chelsea, a neighborhood in London, England.
In 1775, the Battle of Chelsea Creek was fought in the area, the second battle of the Revolution. During the battle, American forces made one of their first captures of a British ship. Part of George Washington's army was stationed in Chelsea during the Siege of Boston.

### 19th century

On February 22, 1841, part of Chelsea was annexed by Saugus. On March 19, 1846, North Chelsea, which consists of present-day Revere and Winthrop, was established as a separate town. Reincorporated as a city in 1857, Chelsea developed as an industrial center and by mid-century had become a powerhouse in wooden sailing ship construction. As the century wore on, steam power began to overtake the age of the sail, and industry in the town began to shift toward manufacturing. Factories making rubber and elastic goods, boots and shoes, stoves, and adhesives began to appear along the banks of Boston Harbor. It became home to the Chelsea Naval Hospital designed by Alexander Parris in 1836.
According to local historical records, Nathan Morse, the first Jewish resident of Chelsea, arrived in 1864, and by 1890, only 82 Jews were living in the city. However, Chelsea was a major destination for the "great wave" of Russian and Eastern European immigrants, especially Russian Jews, who came to the United States after 1890. By 1910, the number of Jews had grown to 11,225, nearly one-third of the entire population of the city. In the 1930s, there were about 20,000 Jewish residents out of a total population of almost 46,000 in Chelsea. Given the area of the city, Chelsea may have had the most Jewish residents per square mile of any city outside of New York City.

### 20th century

On April 12, 1908, nearly half the city was destroyed in the first of two great fires. The fire left 18,000 people, 56 percent of the population, homeless. Many of the city's residents were taken in by those whose homes had survived the fire; others sought refuge in nearby Revere. It would take the city about two and a half years to rebuild and five years to surpass the extent of 1908's infrastructure. The city was also laid out differently after the fire, with wider streets and more access for emergency vehicles.
By 1919, Chelsea's population had reached 52,662, with foreign-born residents comprising 46 percent of the population. Fully transitioned from a suburb to an industrial city, the waterfront flourished, with shipbuilding, lumberyards, metalworks, and paint companies lining Marginal Street. Between 1940 and 1980, the population declined by 38 percent. Chelsea lost more population than other urban areas after the 1950s because of the construction of the elevated Northeast Expressway built to connect the North Shore suburbs to Boston, via the Mystic River Bridge (later renamed for Boston Mayor Maurice J. Tobin).
In 1973, the Second Great Chelsea Fire burned 18 city blocks, leaving nearly a fifth of the city in ashes. Both fires originated in Chelsea's "rag shop district," cluttered streets filled with junk shops hawking scraps, metal, and combustible items. Wood-frame buildings and three- to six-family houses were built tightly together, and quickly caught fire.
By 1990, Chelsea had collapsed economically and socially. Crime was rampant, even among the police and local government officials. The population drain made way for more immigrants but depleted the city's tax base. The cost of running the city and maintaining its infrastructure did not decrease correspondingly so, in 1991, the city suffered fiscal collapse.
The Commonwealth of Massachusetts enacted special legislation to place Chelsea into receivership. For the first time since the Great Depression, a Massachusetts city surrendered its home rule and allowed a state-appointed receiver to control all aspects of city government. Governor William Weld named James Carlin as the first receiver followed by Lewis "Harry" Spence. City Hall was eviscerated, the police and fire departments reorganized, management of the public schools given to Boston University, and indictments handed down. Mayor John "Butchie" Brennan and two former mayors were found guilty of federal crimes.
By the summer of 1995, when the state returned City Hall to the people of Chelsea, a new government had been born, brought to life by a panel of citizens charged with drafting a new city charter. The new charter eliminated the position of mayor, converting management of the city from a mayor to a council–manager government system, where a city manager is selected by City Council members. As such, municipal government focused on improving the quality of services provided to residents and businesses, while establishing financial policies that have significantly improved the city's financial condition.

### 21st century
## Geography

Located on a small peninsula in Boston Harbor covering 2.21 square miles (6 km$^2$), Chelsea is the smallest city by area in Massachusetts. Chelsea is bordered on three sides by water. The Mystic River borders Chelsea to the southwest, the Chelsea Creek and Mill Creek and the Island End River border it to the west.
The topography of Chelsea consists primarily of coastal lowlands, punctuated by four drumlins formed during the last Ice Age. These drumlins are located in the southwest (Admirals Hill), southeast (Mount Bellingham), northeast (Powderhorn Hill), and northwest (Mount Washington). A smaller drumlin (Mill Hill) is located on the east side of Chelsea, adjacent to Mill Creek. This sloped and hilly landscape helps to divide the city into discernible neighborhoods, each with its own character, thereby giving the city a manageable sense of scale and orientation.

### Neighborhoods and districts

There are several distinct neighborhoods in Chelsea:
* Admirals Hill: Admirals Hill sits atop a point of land between the Mystic River and Island End River. Containing the Naval Hospital Historic District, the area is mostly residential development. On the south slope of the hill is the site of the historic Chelsea Naval Hospital. Between the Naval Hospital and the shoreline is Mary O'Malley Park, the largest public park in Chelsea.
* Addison-Orange: Adjacent to the north side of downtown, the Addison-Orange neighborhood is residential, flat, and densely populated. Washington Avenue runs through this neighborhood.
* Bellingham Square: This historic district became the center of commerce and government after the 1908 fire. The design is the result of community planning after the Great Fire of 1908. The district includes City Hall, modeled after Old Independence Hall in Philadelphia, the Public Library, and Phoenix Charter Academy's campus.
* Box District: Just over a block from City Hall, this neighborhood gets its name from various box manufacturing companies that operated in the area as early as 1903, when the Russell Box Company began operations at the foot of Gerrish Avenue. Abandoned in the 1960s, the area was rezoned for residential use in the 2000s.
* Carter Park—Wyndham Area: The neighborhood around Carter Park is a small enclave of mostly single-family Queen Anne style homes. Route 1 is above the southeastern edge of this tree-lined neighborhood, and Revere Beach Parkway winds along the northern edge. The Chelsea High School, Boston's FBI regional field office, MGH Healthcare Center, and Mystic Mall are located in this area. The historic Chelsea Clock Company used to be located in this area until 2015.
* Chelsea Square: This historic district includes a waterfront district (South Broadway neighborhood). Third Street is also in the area, becoming Everett Avenue. The Chelsea Police Department is located here.
* Chelsea Commons: Formerly known as Parkway Plaza, Chelsea Commons sits on a low flat area near the end of Mill Creek, part of which was on a former landfill and clay pit. The plaza consists of big-box retail, fast-food restaurants, and two large apartment buildings. It is bordered by a strip of wetlands on both sides. Webster Ave, Mill Creek Riverwalk, Creekside Common, and Beth Israel Deaconess HealthCare.
* Mill Hill: This largely residential area consists mostly of two- and three-story wood frame detached buildings. Covering the smallest of the city's drumlins, the Mill Hill neighborhood sits on a small neck of land bounded by Chelsea Creek and Mill Creek. This neighborhood is on the Revere line. Eastern Avenue goes through this neighborhood.
* Prattville: This is the northwestern section of the city. It also borders Revere and Everett to the west. Washington Park and Voke Park are located in this area. A smaller Chelsea fire station is located here as well. Garfield and Washington Avenues are in Prattville. Route 1 is on the east side of Prattville, and Route 16 is on the south side.
* Soldiers Home: The Soldiers Home neighborhood covers the steep slopes and the peak of Powderhorn Hill. This residential area contains Queen Anne style architecture. Soldiers Home is one of the least dense neighborhoods in the city. At the peak sits the Soldiers Home, a structure.
* Waterfront District: For the first time, Chelsea is reconnecting with its waterfront. It was established to promote water-oriented industrial uses at Forbes Industrial Park and the lower Chelsea Creek waterfront, its use also remains primarily industrial. Most of the waterfront from the Tobin Bridge to the mouth of Mill Creek is a Designated Port Area (DPA).

#### Economic development

Under City Manager Ambrosino, Chelsea has implemented several innovative data analysis and tracking programs. Many of these programs are led and administered in conjunction with fellows from the Harvard Kennedy School's Innovation Field Lab. According to Chelsea's 2017 "State of the City" report, "this partnership allows the city to benefit from the questions and suggestions of [domestic and] international graduate students." In 2016, the City Council approved a $5.2 million grant for infrastructure improvements in the district. The project has been supported by a newly hired Downtown Coordinator and aims to engage residents and local businesses in a collective effort to advance the economic prosperity and quality of life in the district.
Since the beginning of 2017 City officials kicked off Reimagining Broadway as a way to improve the downtown streets for motorists, pedestrians, and public transit. On July 23, 2019, the Baker-Polito Administration announced the expansion of the Transformative Development Initiative (TDI), a MassDevelopment program for Gateway Cities designed to accelerate economic growth within focused districts. Lt. Governor Karyn Polito made the announcement with MassDevelopment President and CEO Lauren Liss, New Bedford Mayor Jon Mitchell, and members of the New Bedford legislative delegation at the WHALE Co-Creative Center in New Bedford. "Our administration is pleased to further expand this program, which represents an innovative, block-by-block approach to revitalizing local economies." said Governor Charlie Baker.
Chelsea has programs such as "Re-Imagining Broadway" and "Chelsea Centro". The project includes design and parking studies of the corridor from Chelsea Square through Bellingham Square to Fay Square. There are other similar projects like "Commonwealth Places", a collaborative initiative from MassDevelopment and the civic crowdfunding platform Patronicity, and "The Chelsea Business Foundation" are in progress and scheduled for spring/summer 2020.

#### Capital Improvement Plan

As summarized by the "State of the City" report, Chelsea's Capital Improvement Plan will invest in "park development, building improvements, water and sewer upgrades, and neighborhood street/sidewalks improvements. Other specific investments in new graffiti removal and snow removal equipment will enhance the quality of life for residents." The expenditures for Fiscal Year 2018 and Fiscal Year 2018–2022 can be found to the right. Total expenditures are divided between utility enhancement, equipment acquisition, parks and open space, public buildings and facilities, public safety, and surface enhancement. For Fiscal Year 2018, almost 64% of the budget will be dedicated to surface enhancements, which includes citywide sidewalks, marginal street pre-engineering, Shurtleff Street roadway and sidewalks, casino mitigation/transportation, citywide traffic calming, Congress Avenue road and sidewalks, Downtown Broadway engineering and construction, and Highland Street Greenway Phase II.

#### Residential development

Housing Composition: According to the 2011–2015 Community Survey, there are a total of 12,940 households in Chelsea, 27.9% of which are owner-occupied and 72.1% of which are renter-occupied. Although Chelsea has been known as the "City of Renters", there has been a push for home ownership. This has been pushed in particular by the Chelsea Restoration Corporation, which offers educational housing workshops and works in partnership with other state, municipal, and private partners to "rehabilitate properties and increase the stock of affordable housing."
Over half (55.4%) of the housing units in Chelsea use utility gas, 29.8% use electricity, 12.7% use fuel oil, kerosene, etc. and smaller portion (2.1%) of housing units use bottled, tank, or LP gas, as well as other fuel or no fuel at all. With these statistics in mind, Chelsea has started several initiatives towards renewable energy and sustainability. One includes a partnership with SolSmart, a team of individuals dedicated to implementation of Solar energy, by making solar panels accessible through zoning laws, offering affordable solar options and providing education and resources for those who are interested in these efforts.

#### Reimagine Broadway

Reimagine Broadway was a six-month long planning effort that began in 2017 to transform downtown Chelsea, with the guidance of the Chelsea City Council, City Manager Ambrosino and several others. This effort ranges from supporting small business owners to re-designing the streetscape. The goals of this project were to "Enhance how public space is used and accessed downtown, support existing businesses and encourage new growth, beautify the area and create a consistent, vibrant look, improve overall safety for all users, establish a circulation pattern that works for cars, buses, pedestrians, transit riders, and bicyclists."

## Transportation
### Roads

The Route 1 North Expressway is a limited access highway that cuts the City of Chelsea in half. The Tobin Bridge, a major regional transportation artery, carries Route 1 from Chelsea across the Mystic River to Charlestown.

### Train

Chelsea is served by the Massachusetts Bay Transit Authority's Commuter Rail. The Commuter Rail provides service from Boston's North Station with the Chelsea station on its Newburyport/Rockport Line. Some MBTA Bus routes have a link to subway transit systems, including 111, 112, 114, 116, and 104.

### Bus

Chelsea is served by many MBTA bus routes providing local service to East Boston, Revere, Everett, and other nearby cities as well as bus rapid transit connections to Logan Airport and downtown Boston via the MBTA's Silver Line.
The Silver Line's SL3 route to Chelsea has been in operation since 2018. The new SL3 route begins at South Station and runs through the Waterfront Tunnel, along with the SL1 and SL2 routes, to Silver Line Way, continuing with the SL1 through the Ted Williams Tunnel. The new route diverges to meet the Blue Line at Airport Station, and follows the Coughlin Bypass Road (a half-mile commercial-use-only road which opened in 2012) to the Chelsea Street Bridge. The Silver Line stops at the four stations in Chelsea: Eastern Avenue, Box District, Downtown Chelsea, and Mystic Mall. A new $20 million Chelsea commuter rail station and "transit hub" was constructed at the Mystic Mall terminus of the new Silver Line route, so that trains no longer block Sixth Street. The new Silver Line and commuter rail stations are fully handicapped accessible.
Additionally, a multi-use 0.75-mile (1.21 km) shared path 0.75-mile (1.21 km) linear park runs parallel to the Silver Line bus rapid transit busway utilizing the Boston & Albany Railroad's Grand Junction Branch right-of-way. Located within the Box District neighborhood, the path connects Downtown Chelsea and Eastern Avenue stations.

## Education

Chelsea Public Schools has four elementary schools, three middle schools, and one high school, Chelsea High School. The Chelsea school system has historically been towards the bottom of the state's test score rankings. It has a high turnover among students. A high percentage of students move in or out over the course of the year, and the dropout rate is high. In 1988, the school board delegated its authority for control of the school district to Boston University. In June 2008, a partnership with BU ended, and the schools returned to full local control. Chelsea has no private schools remaining with St. Rose closing in June 2020. In addition, there are two public charter schools, the Excel Academy and Phoenix Charter Academy. Bunker Hill Community College and the for-profit Everest Institute have satellite locations of their schools in Chelsea.

## Fire department

The city of Chelsea has firefighters of the City of Chelsea Fire Department, operating from three fire stations across the city, each shift commanded by a Deputy Chief. Chelsea Fire operates an apparatus fleet of four engines, two ladders, two special operations units, a maintenance unit, a foam-tender unit, and several other special, support, and reserve units. Chelsea Fire responds to ~11,000 emergency calls annually. The Chief of Department is John Quatieri who was sworn in on March 8, 2024.
Emergency Medical Services are contracted to private ambulance provider Cataldo Ambulance Service, which has serviced the city since 1982.
