Introduction to the Flood Risk Atlas and its Importance

The State of Mexico’s Governor, Delfina Gómez Álvarez, unveiled the 2025 Flood Risk Atlas (Atlas de Inundaciones edición XXXI 2025) to tackle the challenges posed by atypical rainfall and protect the state’s residents’ property. This strategic tool coordinates preventive and corrective actions in 34 crucial municipalities facing flood risks.

Background on Delfina Gómez Álvarez

Delfina Gómez Álvarez, a dedicated educator and politician, has been serving as the Governor of the State of Mexico since 2017. Her background in education and commitment to public service have made her a prominent figure in addressing the region’s challenges, including natural disasters.

Key Areas and Vulnerable Municipalities

The Atlas focuses on 34 municipalities, primarily those with high vulnerability to flooding. These include Ecatepec, Nezahualcóyotl, Chalco, Naucalpan, Tlalnepantla, Coacalco, Cuautitlán Izcalli, La Paz, Atizapán, Tultitlán, Toluca, Metepec, San Mateo Atenco, and Lerma. These areas are situated in the Valle de México and Valle de Toluca watersheds.

Critical Points and Collaborative Effort

The Atlas identifies 98 critical points across 99 neighborhoods in the mentioned municipalities. These areas face risks due to high population density, overwhelmed drainage systems, unplanned urbanization, and public waste accumulation.

The document was created by the State of Mexico Water Commission (CAEM) using citizen reports and fieldwork from Grupo Tláloc, Protección Civil, and municipal authorities. This ensures a territorial and participatory approach.

Call to Action for Citizens

Beatriz García Villegas, the Executive Vice President of CAEM, reported that 28 Grupo Tláloc camps are operational in 19 strategic municipalities to address immediate infrastructure and hydro-meteorological contingencies.

The Centro de Operaciones de Monitoreo y Concentración de Información (COMCI) remains active 24/7 through the hotlines 800-201-2489 (Valle de México) and 800-201-2490 (Valle de Toluca) for real-time updates and assistance.
