Civil Defense points to trash, erosion and risk of landslides in 11 points in PG

A Defesa Civil de Ponta Grossa survey reveals that 406 homes, with an estimated population of 1,789 residents, are located in areas of care for landslides and floods in the municipality. The data are part of the Municipal Contingency Plan, updated on November 3 and published in the Official Gazette on Wednesday (11).

The analysis of the records shows that the risks are not only associated with the natural conditions of the land. The municipal document itself points to problems such as rubbish accumulated in streams, erosion of the banks, lack of cleaning of valley floors, obstruction of shackles and precarious constructions near slopes.

In all, there are 11 areas of attention distributed in ten locations identified in the registry. Four records deal with landslides and another seven with floods.

Round focuses on two types of risk

The Ronda appears in two different surveys, which add up to 82 residences and 382 potentially affected residents.

In Republic of Panama Street, Defesa Civil identified land with slopes between 45% and 75%, as well as cracks in the ground and trees and inclined poles. Some buildings are situated just 1.5 metres from slopes on the slopes.

At another point in the region, in the vicinity of Arroio da Ronda, the plan records garbage accumulation, erosion of the banks and residences very close to the water course.

The survey gains relevance in the face of the recent history of landslides in the neighborhood, including the tragedy of September 2026, which left three people dead.

Vila Vilela has 370 residents in attention area

In Vila Vilela, Defesa Civil estimates 370 residents in 74 residences located on land with marked slopes, near the Arroio Pião de Pedra.

The document identifies cracks in the ground, inclined poles and trees, erosion of the margins and lack of cleaning of the valley floor.

In the Vila Ana Rita, the conditions are similar. There are 36 residences and 180 residents potentially affected by slope instability and problems related to the stream.

In the Vila Margarida, the plan points to 32 residences and 128 residents in a region with precarious constructions, sloping terrain and the possibility of slipping during rainy periods.

 

Garbage and obstructions aggravate problems

The situation of Boa Vista is one of the examples of risk related to urban infrastructure.

According to the Defesa Civil, the accumulation of garbage can clog two rails through which a stream passes under some residences. Water dams can cause flooding in the region.

In Vila Cipa, the problem identified is the silting of the stream, associated with the proximity of the houses and the accumulated waste.

In Olarias, the register indicates residences built below street level, while in the DER are reported overflows of the stream during heavy rainfall and wastewater in the course of water.

Schools are cited as sensitive points

The document also identifies three educational institutions as sensitive points in the vicinity of the monitored areas: the Professor Meneleu State College of Almeida Torres, in the region of Vila Ana Rita; the Municipal School Prefect Dr. Elyseu Campos Mello, in Ronda; and the Professor Professor School Dr. Othon Mader, in the region of Santo Antônio.

The inclusion of these units in the planning does not mean that their buildings present structural risk or are prohibited, but reinforces the importance of preventive measures in the environment.

Raising requires follow-up

The data represent scenarios of possible damage and do not indicate that all residences are currently banned or in an emergency situation.

The publication, however, allows to identify points that require follow-up and clarification on maintenance of streams, containment of slopes, monitoring of lands and care for families.

The survey is part of version 57 of the Ponta Grossa Contingency Plan, published in the Official Gazette No. 4749, dated November 11, 2026.
