Public works crews in Los Cabos removed more than 64 tons of trash and debris from an arroyo in Colonia Nueva Esperanza, part of the municipality’s push to clear drainage channels before the rainy season hits in July.
The cleanup targeted a dry riverbed running through the residential neighborhood, where garbage, construction debris, and household waste had accumulated. Clogged arroyos are a leading cause of flash flooding in both Cabo San Lucas and San José del Cabo during summer storms, when hard desert soil sends rainwater rushing through urban channels.
Flood Prevention and Ocean Pollution
Public Works Director Manuel Ernesto Montaño Castro said the operation is preventive. When arroyos are blocked, stormwater overflows into streets, damaging homes and infrastructure. He also warned that waste left in the channels eventually washes into the ocean, threatening marine ecosystems and the coastal environment central to the Los Cabos tourism economy.
The problem is not new. After rains in September 2024, crews pulled more than 140,000 pounds of trash from Cabo San Lucas beaches alone. Earlier this year, the Los Cabos General Directorate of Ecology and Environment announced a zero-tolerance policy for illegal dumping in arroyos, threatening significant fines and administrative sanctions against individuals and companies caught using the riverbeds as dumps.
Broader Cleanup Campaign Across Los Cabos
La Paz is conducting similar work. City officials there have begun removing vegetation, trash, and sediment from streams and bridges ahead of what forecasters expect to be an active storm season running from July through October.
In Los Cabos, the arroyo cleanup at Colonia Nueva Esperanza is one piece of a larger municipal campaign. Last September, a separate operation in the La Ballena area removed more than 105 tons of waste using six trucks and heavy machinery. Municipal officials say permanent cleanup operations will continue across Los Cabos under orders from Mayor Christian Agúndez Gómez.
Residents are being urged to stop dumping trash in arroyos and vacant lots. Officials remind the public that collection services and authorized waste centers exist for disposal of debris and special waste. Los Cabos holds 25 Blue Flag beach certifications, more than any other municipality in Mexico, and keeping arroyos clear is considered essential to maintaining those designations.
