GLOwanus–Using Light To Influence Water Quality

Brooklynites can turn to this lantern made of recycled plastics the next time a city-issued waterbody advisory is issued.

It’s scary to think that a combined sewer overflow (CSO) could be happening on your streets even when it’s not visibly flooding.

A CSO can be caused by as little as a 1/12 of an inch of rain and can result in sewage being carried into the Gowanus Canal, hindering clean-up efforts. At the time of a CSO, all water is diverted into the Gowanus Canal. By reducing water consumption, the CSO is reduced, keeping the canal healthier, cleaner, and vibrant.

GLOwanus was created to make NYC waterbody advisory alerts easier to understand for residents. When the city issues an alert for the Gowanus Canal, the lantern will emit vivid colors and continue to do so until the waterboard advisory is lifted. When the colored lights come on, this tells residents that they should be cutting back on their water usage, whether that be waiting to wash dishes, flush the toilet, or do the laundry.

GLOwanus was created by Francesca Bastianini (Sight Studio) and Steven Koller (Environmental Science and Policy PhD student), two fellows from Van Alen Institute’s Neighborhood Design Fellowship program, and was designed by artists Manav Singla and Ridima Jain.

The Gowanus Canals are a superfund site. According to Bastianini, this means that despite the rapid change and development of the neighborhood, it is still undergoing repair from a long history of pollution, and ongoing pollution from an overwhelmed sewer system.

According to Andrew Brown, the Director of Programs at Van Alen, when there’s no city-issued waterbody advisory, the light glows white. When an advisory is issued, the light flashes different rainbow colors. Each color doesn’t specifically mean something, but the rainbow colors are meant to draw people’s attention so that they realize there is a City-issued waterbody advisory, meaning there’s a good chance combined sewage overflow (CSO) has recently spilled or may soon spill into the Canal.

The lanterns are made out of recycled plastics, creating a durable and translucent product that transmits light all around and avoids creating new plastic. According to Bastianini, the prototype of the lantern was created from the VAI Gowanus fellowship in 2021, and the current product was completed in the fall of 2023.

Instructions for the open-source code and 3D printing for the lantern are available. Shiloah Coley, the Program Associate at Van Alen, says that providing this information to the public makes it easier for other communities and neighborhoods that are interested in creating a product like the GLOwanus lantern to do so.

“We learned so much working on this, and we want to make sure other communities and individuals have access to this knowledge and feel encouraged to build on it,” explained Coley.

Bastianini hopes that the GLOwanus lanterns will not only expand on a large public scale, but expand awareness, provide prompts and support for local advocacy, and keep “pressure on agencies to follow through with their local officials.”

Coley hopes the lanterns help Gowanus residents feel empowered by providing the information they need during a CSO.

“That way if they choose to, they can act and adjust their own water usage habits. It would be great to see other folks build on our open-source code to make light installations in other neighborhoods.”

Approximately 20 to 25 GLOwanus lanterns are left at time of press. If anyone is interested in picking one up, you can email Shiloah Coley at scoley@vanalen.org.

Big win for Gowanus rezoning

Recent developments reveal an increasing support for the Gowanus rezoning.
Last week, Borough President and Democratic nominee for mayor Eric Adams formally announced his support for the ambitious zoning change.
Although borough presidents only have an advisory role in the land use process, Adams support for the neighborhood-wide rezone is a telling sign that the Democratic nominee would continue to advocate for similar developments if he is elected mayor.
“New York City is always changing, but every once in a while we need a sea change, and that’s what I believe we are embracing now,” Adams said during a press conference.
Adams made it clear that his support was contingent upon the rezoning’s commitment to funding public housing. Multiple NYCHA developments, including the Wyckoff Houses, are included within the area planned for rezoning, but the borough president is hopeful that the money put towards the rezoning will also assist low-income residents.
“This is about investing in public housing,” Adams explained. “Buildings cannot go up around NYCHA developments while residents see their futures go down.”
The Gowanus Rezoning has previously been criticized for opening the neighborhood to increased displacement and gentrification.
However, a new Racial Equity Report on Housing and Opportunity created by the City Council in collaboration with the Fifth Avenue Committee and Columbia University Urban History Professor Lance Freeman found that the zoning change would in fact make the neighborhood more diverse.
The report took neighborhood demographics and income into account, and determined that 20 to 25 percent of the new apartments coming to the neighborhood through the rezoning are projected to be filled by Black residents, while 25 to 37 percent are projected to be filled by Hispanic residents.
Currently, the area slated for rezoning is more than 60 percent white.
“In 2021, New York City remains one of the most highly segregated and unequal cities in the United States,” read the report. “Persistent disparities in access to economic opportunity, quality education, healthcare, housing, and open space have been revealed and exacerbated by a pandemic that disproportionately affects Black and Latino communities.
“Until recently, broad goals of citywide economic growth and housing production without specific regard to racial or socio-economic equity have long dominated the policymaking process,” it continued. “This model of pursuing ‘color-blind’ growth within a vision of New York as a global capital of finance, culture, and tourism continues to influence the City’s overall policy direction and has yet to be fully reckoned with.”
The Gowanus Rezoning was approved on June 24 by community boards 6 and 2 after many months of pushback and legal challenges.
The proposal was originally conceived during the administration of former mayor Michael Bloomberg, but found new life under Mayor Bill de Blasio. It will see 80 square blocks of the neighborhood rezoned to make way for new developments, including the controversial plan to build a complex on the highly polluted Public Place site along the Gowanus Canal.
The rezoning will bring approximately 8,500 new housing units to the neighborhood, including 3,000 units that would be permanently affordable.
Community groups, including the grassroots organization Voice of Gowanus, criticized both the legal process to approve the rezoning and the environmental risks that could come along with new development.
The group successfully secured a temporary restraining order that prevented the rezoning from entering the land-use review process, yet the ruling was soon reversed by New York Supreme Court Justice Katherine Levine.
At the time of the rezoning’s approval, many local politicians and community members were still wary of the negative impact the rezoning would bring. Councilman Brad Lander and members of Community Board 6 both expressed their dismay that additional NYCHA funding was not included in the rezoning proposal, and called for the city to conduct a larger study of the rezoning’s potential impact on racial equity.
With the release of the new report last week, these political figures have begun to change their tune.
“As our public statements, communications to the city, and final vote to conditionally approve the Gowanus rezoning made clear, we supported a racial impact study and are glad to see one has been done,” said Mike Racioppo, district manager of Community Board 6. “More important than the study being done are the results of the study, which show Gowanus could become more diverse after the rezoning.”
In addition to the Racial Equity Report, local activists continue to demand that the city support and fund a Gowanus Zoning Commitment Task Force to maintain a steady stream of communication with members of the community.
“The task force will monitor compliance with public and private commitments, adherence to zoning requirements, and implementation of the rezoning,” board leaderhips wrote in a joint statement.

DCP releases new Gowanus revitalization vision

The Department of City Planning (DCP) unveiled its guidebook for future development in Gowanus.
The 118-page document, titled the Gowanus Industrial Business Zone (IBZ) Vision Plan, offers suggestions and goals for commercial, industrial, and residential growth in the Brooklyn neighborhood.
“The Vision Plan that we’re releasing today contains recommendations for infrastructure and workforce training, and lays out a land use framework that will help keep the Gowanus portion of the IBZ a bustling and dynamic jobs hub for decades to come,” explained DCP director Marisa Lago in a statement.
The new document represents the culmination of a multi-year effort to organize a comprehensive plan for the historically industrial area.
While researching for the study, DCP worked closely with Councilman Brad Lander, held multiple town hall meetings with members of Community Board 6, and consulted various environmental experts.
The study area included about 20 blocks of the neighborhood between Third and Hamilton avenues to Third Avenue and 16th Street.
“While the Gowanus IBZ continues to flourish as a local employment hub, the existing zoning has remained largely unchanged since 1961, limiting the ability for businesses to grow and expand,” explains the document’s opening statement. “The study’s core goals are to put forth a land use framework that can inform future private land use applications, and identify infrastructure and workforce development opportunities that can reinforce the area as a 21st century jobs hub.”
Topics addressed in the final document include land use, transportation, infrastructure, and workforce development. A great amount of the guide is also dedicated to strategies for cleaning the highly polluted Gowanus Canal.
Primarily, the guide urged the Department of Environmental Protection to build capture tanks that will reduce sewage and stormwater runoff from going into the canal.
The plan comes on the heels of a months-long controversy surrounding a rezoning of a large majority of Gowanus. The rezoning was originally conceived by ex-Mayor Michael Bloomberg but has found new life under Mayor bill de Blasio.
It would rezone 80 square blocks of the neighborhood to make way for new developments, including a controversial plan to build a complex on the highly polluted “Public Place” site along the Gowanus Canal.
Community groups including Voice of Gowanus have consistently opposed the rezoning. Their criticism is directed at both the legal process to approve the rezoning and the environmental risks that could come with new development.
The group successfully secured a temporary restraining order that prevented the rezoning from entering the land use review process. However, New York Supreme Court Justice Katherine Levine ruled to allow the city to continue with the public review process so long as an in-person hearing option was offered for those without internet access.
The in-person hearing will take place at J.J. Byrne Playground in Park Slope and will coincide with the virtual hearing. The date and time are yet to be announced.
The Gowanus Industrial Business Zone (IBZ) Vision Plan supports the rezoning and is largely built on the assumption that the measure will pass. However, the ULURP process typically takes seven months, leaving time for a new mayor and City Council to change course in Gowanus.

Judge rules Gowanus rezoning can move forward

This past Monday a Brooklyn judge lifted the temporary restraining order on the controversial Gowanus rezoning. The land use proposal is now allowed to move ahead to the public hearing phase of the approval process after months of bitter legal battles.
The rezoning was originally conceived by ex-mayor Michael Bloomberg, but found new life under Mayor Bill de Blasio.
It would rezone an 80-square-block area of the neighborhood to make way for new developments, including a controversial plan to build a complex on the highly polluted “Public Place” site along the Gowanus Canal.
The grassroots community group Voice of Gowanus, as well as other elected officials and organizers, have consistently opposed the plan. Their criticism is directed at both the legal process to approve the rezoning and the environmental risks that could come with new development.
In a meeting last month, Voice of Gowanus members argued that the Uniform Land Use Review Procedure (ULURP) for city projects should be halted during the pandemic. Alicia Boyd from the Crown Heights group Movement to Protect the People, explained how Virtual ULURP hearings were inaccessible for many New Yorkers.
“Forty percent of our community did not have access for an online hearing,” Boyd explained. “It’s another way to silence people’s voices, there is no way to protest.”
Jason Zakai, an attorney for the group, applied for a motion from the courts that would compel the city to conduct ULURP in person or otherwise more adequately, resulting in the restraining order.
“Before we even get to the political process, we need to make sure it is done correctly,” Zakai explained during last month’s meeting. “We want the city to follow New York City law.”
This past week, that restraining order was reversed when New York Supreme Court Justice Katherine Levine ruled to allow the city to continue with the public review process so long as an in-person hearing option was offered for those without internet access.
The in-person hearing will take place at J.J. Bryne Playground in Park Slope and will coincide with the virtual hearing. The date and time are yet to be announced.
However, Voice of Gowanus is still fighting the rezoning.
“The lifting of the temporary restraining order was provisional and contingent upon the city meeting certain requirements, which it has not yet done,” Zakai clarified in a new statement. “The court proceeding continues, and Voice of Gowanus will not waver in its fight on behalf of the community to ensure there is increased public participation, access, and transparency at any public hearings on the massive and controversial rezoning plan.”
Despite the pushback, the two City Council members representing the area — Brad Lander of and Stephen Levin — support the rezoning. In a statement, Lander’s Land Use and Budget director Julia Ehrman spoke of the need for the rezoning and the importance of forthcoming environmental review processes.
“The Gowanus neighborhood has been changing around us with as-of-right development over the last decade,” Ehrman wrote. “As we emerge from the pandemic, we have a chance to steer its future in the direction of a more integrated, affordable, and resilient community.
“Now that the public process is moving forward, we can have the conversations we need to ensure the rezoning plan addresses critical issues in Gowanus,” she added, “including the clean up, infrastructure, and funding for NYCHA.”
The Gowanus Canal is one of the most polluted waterways in the world, due in large part to its history as a former hub for industry.
Voice of Gowanus members are concerned that development along the waterway, especially at the Public Place site, could release residual contamination into the neighborhood.
Yet even as the rezoning moves towards public hearings, there is no guarantee that the project will see the light of day. The ULURP process typically takes seven months, leaving time for a new mayor and City Council to change course in Gowanus.
