A proposed 300-plus-unit residential development near La Paz’s Palmira Estuary has drawn opposition from residents and environmental groups, adding a second large project to a stretch of coastline already entangled in permit disputes. The La Paz wetlands development would place 10 buildings of up to seven stories on a 2.7-acre site next to the Humedales El Mogote-Ensenada de La Paz, a wetland system protected under international treaty. No official permits or detailed plans have been publicly confirmed by authorities.
The proposal arrives while a separate project, Balaena Costa Apartments, has resumed construction on the same wetland perimeter. That seven-story luxury condo was shut down by federal authorities in July 2025 for lacking required environmental permits. It is now back under way after receiving authorization from SEMARNAT, Mexico’s federal environment ministry.
Ramsar and AICA Protections Cover the El Mogote Wetland System
The Humedales El Mogote-Ensenada de La Paz earned its Ramsar designation in 2009 under the Ramsar Convention, an international treaty signed in 1971 that commits member nations to conserve wetlands of global ecological importance. Mexico has 144 Ramsar sites, more than any other country in the Americas. A Ramsar listing does not ban development outright, but it obligates Mexico to maintain the “ecological character” of the site through land-use planning and environmental review.
The same wetland system also holds an AICA designation, which stands for Área de Importancia para la Conservación de las Aves (Area of Importance for Bird Conservation). AICA sites are identified by CONABIO, Mexico’s national biodiversity commission, and the international organization BirdLife International. The La Paz estuary supports over 200 bird species, including reddish egrets, roseate spoonbills, and several migratory shorebird species that travel the Pacific Flyway between Alaska and Central America.
The mangrove forests lining the estuary also serve as nursery habitat for fish and invertebrates. Whale sharks feed in the bay’s plankton-rich waters between October and April each year. Both the mangroves and the whale shark population are central to La Paz’s ecotourism economy, which generates tens of millions of pesos annually from snorkeling tours, kayak excursions, and guided birdwatching.
Balaena Costa Resumed Construction After July 2025 Federal Shutdown
The Balaena Costa project’s path illustrates how environmental enforcement works, and stalls, in practice. In July 2025, PROFEPA (Mexico’s federal environmental enforcement agency) ordered a “total and definitive closure” of the construction site. The agency found that the developer had begun building without the Environmental Impact Authorization (MIA) required by SEMARNAT for any project inside or adjacent to a protected ecosystem.
PROFEPA inspectors also documented damage to coastal sand dunes and disruption of natural water drainage patterns. Environmental groups including Las Guardianas de los Manglares, a La Paz collective of women activists focused on mangrove conservation, and CEMDA (the Mexican Center for Environmental Law) filed formal complaints. They alleged the construction had destroyed native dune vegetation and threatened ongoing mangrove restoration work in the estuary.
Yet by early 2026, SEMARNAT authorized Balaena Costa to resume. State authorities said the project now complied with applicable environmental and forestry regulations. The developer began marketing and selling ocean-view units on a pre-sale basis. For critics, the reversal raised questions about whether a federal shutdown carries lasting consequences or functions as a temporary pause that developers can outlast through the permitting process.
La Paz Water and Sewer Systems Already Under Strain
Both projects would add hundreds of residents to a corridor where infrastructure is already stretched. La Paz draws most of its drinking water from a depleted aquifer. CONAGUA, Mexico’s national water commission, has classified the La Paz aquifer as overexploited since 2009. The city’s water utility, OOMSAPAS La Paz, has struggled to maintain consistent service in newer developments along the Palmira and Coromuel corridors, areas where much of the city’s recent residential and hotel construction has concentrated.
Sewage capacity is another concern. La Paz’s main wastewater treatment plant operates near its design limit. Untreated or partially treated wastewater discharges into the bay have been documented repeatedly. Adding over 300 residential units in one project, plus the Balaena Costa condos, would increase demand on both water supply and sewage processing in a zone with limited spare capacity.
Traffic on the coastal boulevard connecting Palmira to downtown La Paz has also worsened as hotels and residential towers have multiplied along the waterfront over the past decade.
How Residents Can Engage the Permitting Process
Under Mexican environmental law, projects near protected ecosystems require a Manifestación de Impacto Ambiental (Environmental Impact Statement), known as the MIA. When a developer submits a MIA to SEMARNAT, the agency must open a public comment period. Citizens can submit written observations, and SEMARNAT is required to consider them before issuing or denying the permit.
Residents can also request a public information meeting (reunión pública de información) through SEMARNAT’s regional office in La Paz, located on Paseo de los Deportistas. CEMDA has published guides in Spanish on how to participate in the MIA process, available on its website. Las Guardianas de los Manglares post updates and calls to action on their social media channels and have organized community forums on previous development proposals in the estuary zone.
No MIA for the proposed 300-unit project has appeared in SEMARNAT’s public registry as of this writing. The next scheduled session of La Paz’s municipal planning commission (IMPLAN) could provide the first official forum for public input.
