Projections show that the coastal strip corresponding to Carrasco will be compromised. The major problems arising from frequent or permanent flooding in the area will impact the neighborhood's population and also those who frequent its
beaches in the summer.

Marrero said that, "Were we to be left without a beach in Carrasco, there would be an impact on those who live on the coastline, as they will see their environment modified." For example, the Carrasco Sofitel Casino Hotel is located in an area susceptible to flooding, as well as the entrance to and exit from Arocena Avenue, the neighborhood's main commercial avenue, along the Rambla.

"And there will be an impact on the people who go to the beach in summer," affirmed Marrero. The sociologist said that within the framework of the National Adaptation Plan for the Coastal Zone in the face of Climate Change, qualified informants from the neighborhood were consulted who "told us that the people who live in Carrasco do not use the neighborhood's beach. Some people may go jogging or walking but those who use the beach during the summer season are people from the outlying neighborhoods of Montevideo, who cannot spend the summer in the beach resorts east of the country."

In addition, forecasts predict that, around 2100, extreme events will flood the Carrasco waterfront promenade, one of the main land connections between Montevideo and Canelones.

This forecast contrasts with the strong migration trend from Montevideo to Ciudad de la Costa that has taken place since 2000. Between 1996 and 2011, the population of this area grew by 37.4%. As a result, the national and departmental governments improved the road infrastructure. During the 2000s and 2010s, the entire waterfront road from Canelones to El Pinar, which connects the seaside resorts of Ciudad de la
Costa with the Rambla of Montevideo, was widened with a dual carriageway.

In 2009, the two bridges over Arroyo Carrasco that connect the Montevideo and Canelones waterfront avenues were also inaugurated, which investment amounted to 100 million pesos at the time.

The population to the west of Montevideo, on the mouth of the Santa Lucía River, will face other challenges.

The capacity of the city's drainage system was frequently exceeded in several episodes of heavy rains. In 2022 the rains caused Arroyo Malvín to swell, flooding homes on Concepción del Uruguay Street where the old creek was channeled.

In Malvín neighborhood, the streets were flooded when two phenomena were combined: an extreme event -the southeast wind that caused the Río de la Plata to overflow, not allowing the drains and micro-basins to discharge-, combined with heavy rainfalls that caused Arroyo Malvín to also overflow, which prevented the discharge of the neighborhood's storm drains. However, this situation is not due to climate change but to the climatic variability associated with the micro-basins.

"Montevideo was the first city in Latin America to create a water and sanitation system," states a report issued by the Inter-American Development Bank, IDB. "Its construction began in 1886, shortly after cities like London and New York implemented such systems. Over the years, the population multiplied and with it the demand for water grew, but the pipes were never renewed. Eventually, the infrastructure proved to be insufficient."

In 2011, 2014, 2015, 2018, 2020 and 2022 heavy rains flooded several points of the city, such as the neighborhood of La Aguada, in front of the former AFE Central Railway Station, Jacinto Vera at the intersection of Bulevar Artigas and Garibaldi, La Comercial, and several of the lower areas of Bulevar José Batlle y Ordoñez.

In 2011 the national and local government began works to expand the capacity of the drainage network: huge subway tanks of millions of liters were built to capture excess water, as buffers, and prevent flooding of the streets. The tanks were financed with a $25 million loan from the IDB. By 2022, 5 tanks had been built.
