Residents of the Ejido José María Pino Suárez in southern Tulum reported alleged environmental damage in recent months, accusing businessman Helio Alejandro Monforte Jaimes of carrying out earthmoving works with heavy machinery in an ecologically sensitive area. According to the residents, the activities have affected mangroves and wetlands and have continued despite previous environmental warnings and restrictions.

The complaints focus on a proposed mixed-use tourism and residential development known as Pastizales, planned over 42.2 hectares within the agrarian nucleus. The site is located near the Nopalitos lagoon and just a few kilometers from the Sian Ka’an Biosphere Reserve, an area internationally recognized for its environmental sensitivity and limited infrastructure capacity.

Local residents say the works have been ongoing for several months and involve clearing and land modification in zones classified as wetlands and mangrove ecosystems. They argue that these ecosystems are legally protected and play a crucial role in flood control, biodiversity conservation, and the stability of the region’s hydrological systems.

Allegations of unpermitted environmental impacts

According to the residents, the use of heavy machinery has altered natural water flows and caused visible damage to mangrove vegetation. Mangroves in Mexico are protected under federal law, and any removal or alteration typically requires specific authorizations and mitigation measures.

Several inhabitants said that the scale of the works suggests preparation for large-scale construction rather than minor land management. The Pastizales project, as described by the complainants, would include approximately 540 hotel rooms and residential units, representing a significant increase in density for an area designated for low-impact use and conservation.

The residents contend that the area is already under pressure from previous developments approved in earlier years. They estimate that around 10,000 housing units in the broader region remain unoccupied or are not in full operation, raising questions about the necessity of additional large projects in environmentally fragile zones.

Project location raises regulatory concerns

The proximity of the proposed development to protected natural areas has been a central point of contention. The Nopalitos lagoon forms part of a broader system of wetlands and surface water bodies that connect hydrologically with surrounding ecosystems.

Residents argue that the location of the project conflicts with land use restrictions established in local and regional planning instruments. In particular, they cited the Local Ecological Land Use Program of Tulum, known by its Spanish acronym POEL, which sets strict limits on density, construction types, and permissible activities in areas classified for environmental preservation.

According to the complaints, the project area falls within zones intended for low-density use due to its ecological value and vulnerability to environmental degradation. Any deviation from these guidelines, they argue, increases the risk of long-term damage not only to natural habitats but also to surrounding communities that depend on ecosystem services such as flood mitigation.

Conflicting positions among federal authorities

One of the most sensitive aspects of the case involves the role of federal environmental authorities. Residents stated that the National Commission of Natural Protected Areas had previously determined that the Pastizales project was not environmentally viable, citing its proximity to protected areas and existing regulatory restrictions.

Despite that assessment, residents allege that the Secretariat of Environment and Natural Resources later granted environmental impact authorization for the project. The apparent contradiction between agencies has fueled mistrust and confusion among community members.

Environmental regulations in Mexico require that projects of this scale undergo a detailed environmental impact assessment. Such assessments are intended to evaluate cumulative impacts, especially in regions already experiencing development pressure. Residents argue that cumulative impacts were not adequately addressed in this case.

Claims of past enforcement failures

Community members also raised concerns about enforcement and oversight. According to several residents, environmental authorities had placed closure seals on the property in previous years due to irregularities. They claim those seals later disappeared, and work resumed without clear explanations or public updates on compliance measures.

These allegations have intensified suspicions of irregularities and insufficient monitoring. Residents emphasized that transparency is essential, particularly in areas where environmental degradation can be difficult or impossible to reverse.

While no official confirmation has been issued regarding the alleged removal of closure seals, residents insist that the pattern reflects broader challenges in enforcing environmental law in fast-growing parts of the Riviera Maya.

Environmental saturation and urban strain

Beyond the immediate environmental impacts, residents warned of broader urban and infrastructural consequences. They argue that southern Tulum is already experiencing saturation from previously approved developments that have strained roads, water management systems, and waste disposal capacity.

The addition of hundreds of new rooms or residential units, they say, would further stress an area not designed to support high-density tourism or residential use. This concern is particularly acute in zones with wetlands, where altered drainage can increase flooding risks during heavy rains and hurricanes.

One resident summarized the concern by saying the environment is delicate and cannot withstand additional pressure. Mangroves and lagoon systems, they stressed, do not recover quickly once damaged, and their loss would have lasting consequences for wildlife and local communities alike.

Calls for independent verification and review

In response to the ongoing works, residents called for environmental organizations and competent authorities to conduct on-site inspections and independently verify the activities taking place on the property. They are requesting a review of the legal basis for the authorizations granted, as well as confirmation that all technical opinions and mitigation requirements are being fully respected.

They also urged authorities to assess whether the project aligns with existing land use plans and environmental protection policies. According to the residents, restoring public trust will require clear communication, transparent decision-making, and visible enforcement actions where violations are found.

The situation highlights ongoing tensions between development interests and environmental protection in Tulum, a municipality that has seen rapid growth over the past decade. As The Tulum Times has reported in previous coverage, balancing economic activity with ecological preservation remains one of the region’s most complex governance challenges.

The dispute over the Pastizales development underscores what is at stake for communities living near sensitive ecosystems and for regulators tasked with safeguarding them. Whether the alleged environmental damage will be formally confirmed and what actions may follow remain unresolved, but the controversy has renewed attention on environmental oversight in southern Tulum and the future of development near protected areas.
