In San Juan, Puerto Rico, government, residents, and technical professionals created a Community Land Trust (CLT), known locally as Fideicomiso de la Tierra, to preserve and develop informal communities along the Martín Peña Canal. A specially created public corporation, ENLACE, regularized land holdings in the communities, developed fair relocation procedures that compensate residents in at-risk areas, and protected this centrally-located community from gentrification through the establishment of a community-managed CLT.

The eight Martín Peña communities’ struggles are reminiscent of the experience in many Rio favelas and similar communities around the world. In the 1930s, a devastating hurricane season forced rural workers into unemployment and migration to San Juan surged. Faced with a housing shortage, migrants eventually built 5,000 informal homes along the Martín Peña Canal, which was a major economic and transportation artery through the city. Today, the communities’ population nears 30,000 and it is the most densely populated area in Puerto Rico.

The communities were historically underserved by the government. Informal electricity connections created fire risks and the communities’ narrow alleys prevented emergency vehicle access. Government failure to install proper sewage systems or clean the canal left the area extremely prone to flooding.

The canal became so polluted that it stopped flowing. Sections of the canal that used to be 60-120 meters wide are now maybe one meter wide, and filling has reduced depth from 2.5 meters to a less than 10 cm. In a 2015 report, the US Environmental Protection Agency (EPA) estimated that over 3,000 buildings still discharged raw sewage into the canal.

Calls to dredge the canal prompted government action. In 2001, San Juan and the US Army Corps of Engineers committed to a far-reaching project to dredge the canal and restore water flow. Because the lack of a formal sewage system was a major source of pollution, the government also committed to revitalizing the canal communities.

Before work began, two employees from the Transportation Authority visited the communities to talk with residents about the project. Under their leadership, the government ultimately held 700 participatory meetings in the communities from 2002-04. In the meetings, experts responded to community concerns and presented on legal tools to preserve affordable housing and formalize landholdings.

Residents were united in wanting to ensure that dredging the canal and the revitalization that would accompany it would not serve to displace them. Their top priority, like many in Rio favelas, was to maintain their community. Residents decided a Community Land Trust model was the best way to achieve their goal because there would be a collective, rather than individual, land title. Meeting participants also developed a plan for the District comprised of the eight communities. This Comprehensive Development Plan would guide the project going forward.

In 2004, residents created the Group of Eight Communities (G-8), a non-profit corporation, to promote their economic, social, and community development throughout the establishment and maintenance of a CLT. The G-8’s board is comprised of representatives from 12 community organizations who are chosen annually in community assemblies. Today, the G-8 facilitates communication between ENLACE and the CLT, and ensures compliance with the Comprehensive Development Plan.

In September 2004, San Juan passed Law 489/2004. The law, informed by the Comprehensive Development Plan, created the Martín Peña Canal Special Planning District and public corporation ENLACE, and provided for the future incorporation of the CLT. The District refers to an area including seven communities along the canal that would make up the CLT.

ENLACE is an arms-length, limited-lifespan, independent government agency that oversees and coordinates project implementation and is mandated to be “responsible for coordinating the implementation of all aspects of the Project: including…housing development, infrastructure, the dredging and canalization of the Canal, as well as urban and socio-economic development” and “to guarantee mechanisms for citizen participation in the planning and execution of the ENLACE Project and promote community empowerment.”

The Governor of Puerto Rico and Mayor of San Juan appoint ENLACE’s board of directors, which is made up of representatives from the public and private sectors and of community residents. The mayor and governor select community resident board members, which must make up at least 45% of the board, from a list of candidates prepared by the G-8.

Prior to Law 489, most housing in the District was informal—residents had built houses without official permission on government land. To create a CLT, land holdings had to be regularized and title transferred from the government to the CLT. Under the new Law 489, title to any land in the District owned by Puerto Rico or San Juan now automatically transferred to ENLACE.

Prior to transferring title to the CLT, ENLACE worked to regularize property rights. Residents were granted surface right deeds with a right to inherit and maintain ownership of their home, while ENLACE retained title to the land beneath. This separation insulates residents from rising real estate values—they are able to capitalize on the rising values of the home itself, but not of the land underneath.

Per Law 489, ENLACE would transfer land title to the Community Land Trust that would be created, only after regulations governing the CLT’s operations were established. From 2006-2008, the G-8 and ENLACE organized three rounds of community workshops to develop the CLT’s General Regulations. An Advisory Board and lawyers supported the process so that residents’ needs and requests would be formalized legally.

The General Regulations were promulgated on Oct. 21, 2008. They stress the CLT’s role as a “mechanism of collective possession in order to solve the problem of the lack of ownership titles” and to “avoid involuntary displacement” of canal residents. This reflects the purpose of the CLT set out in Law 489: “to contribute toward the solution of the ownership rights problem of many district residents through collective land-holding.” With Regulations complete, ENLACE transferred the land to the CLT by formal deed on May 14, 2009.


The CLT has been operating successfully under the Regulations for eight years, and in partnership with ENLACE has made significant progress towards being self-funding and relocating residents humanely and as necessary to dredge the canal. In 2015, it won a Building and Social Housing Foundation World Habitat Award recognizing it as a model for other informal communities.

The CLT is run by an 11-member board of trustees which has a duty to administer the CLT for the community’s benefit. The G-8 selects a total of six board members: four who are residents and leaders of community organizations and two who need not be residents or leaders of community organizations. The board of directors of ENLACE chooses one of its own members, who is neither part of the G-8 nor the government, to serve on the board. The CLT’s board itself chooses another two members. The Mayor of San Juan and Governor of Puerto Rico each appoint a government representative to the board. Additionally, the president of the G-8 serves as a non-voting member of the board.

According to the Regulations, the CLT must work to resolve land title problems in the District, avoid involuntary displacement of residents, acquire and maintain properties for the community’s benefit, and facilitate resident involvement. When working toward these objectives, the CLT must follow guiding principles, which include promoting resident participation in decision-making; encouraging equality, safety, and access to basic services; and improving public spaces and transportation.

Among the CLT’s most important duties is developing housing and keeping it affordable. To make sure the CLT achieves this goal, the Regulations provide that the CLT cannot resell land and can only sell or rent housing for the members’ benefit. When a resident decides to sell, the CLT has an option to buy back the home, so that it then resells the home at an affordable price. When residents mortgage their homes, the CLT appears on the mortgage and has the option to buy back the home if the resident defaults on loan payments. To support residents with loans, the CLT also provides financial education to families.

The CLT aims to be fully self-funding once relocations are complete and ENLACE’s lifetime has expired. The CLT makes money from selling homes, renting property, investing in the community, and receiving donations. Regulations require that the CLT reinvest profits into the communities through a revolving fund for infrastructure projects, buying property, and other priorities set in place by the Comprehensive Development Plan.

When a resident sells their home, the proceeds go in part to the resident and in part to the CLT. This sharing scheme considers that the increase in home value came from two sources: the resident’s investment in the structure, and the CLT investments in the surrounding community.

Currently, the CLT receives significant subsidies from both the public and private sector. The CLT also relies on a significant amount of volunteer work to meet its budget. While these two factors could leave potential for long-term financial instability, the CLT has been stable to date.

One of ENLACE and the CLT’s most difficult tasks is relocating residents whose homes were so close to the canal that they must be removed for the EPA to dredge the canal. In total, 1090 households must be moved; so far, ENLACE has successfully relocated 110.

The relocation process begins with a visit from a Relocation Committee made up of other residents who have also been through the relocation process. The Committee visits the household and conducts an assessment to find out what support the family needs during the relocation process. ENLACE has a third party assess the value of the home, provide residents with an offer, and assist them in finding a home for sale within or outside the District. ENLACE supports the family throughout the entire process, including paying moving expenses.

The Martín Peña Canal CLT, Fideicomiso de la Tierra, as it is known to residents, is successfully working towards permanent preservation and affordability in the Martín Peña Canal communities and can serve as a helpful model for other informal communities around the world, as they struggle with the conflict between development and gentrification, in years to come.


This article originally appeared on on April 28, 2017. Rio Olympics Neighborhood Watch (RioOnWatch) was started by Catalytic Communities, a US nonprofit and Rio de Janeiro-based NGO, to bring visibility to favela community voices in the lead-up to the 2016 Olympics. RioOnWatch brings attention to the perspectives of community organizers, residents, international observers, and researchers on the fast-paced urban transformations in Rio.

Beginning in 2017, RioOnWatch's new editorial line is committed to:

  • Documenting favela residents’ views of and for public policy so as to inform municipal decision-making and international development professionals.

  • Publishing favela-specific columns and opinion pieces written by residents so as to mainstream favela perspectives on their own communities.

  • Highlighting organizing strategies, community solutions and green technologies from favelas in Rio and around the world so as to inform and inspire collaborative and sustainable grassroots development initiatives.

  • Popularizing urban planning concepts so citizens can develop their communities more effectively.

  • Observing the Olympic legacy and monitoring international and domestic press coverage of favelas so as to maintain and build on the legacy of RioOnWatch as an Olympic watchdog news site and offer lessons for cities contemplating or hosting mega-events.

  • Analyzing parallels and showing solidarity for informal communities around the world so as to establish connections, networks of support, and a sense of common experience and purpose across traditionally isolated communities worldwide (and in partnership with groups or sites similar to CatComm/RioOnWatch).

  • Continuing to analyze, introduce and inform local policy and social debates on Rio so as to dramatically strengthen the contextual understanding and compassion necessary to engender larger political shifts that would benefit the entire society.

Progressive City has partnered with RioOnWatch to reprint articles in order to increase awareness and bring attention to urban issues in Rio. For additional information and articles, please visit
