Itapema Plans Beach Widening as Erosion Meets Brazil’s Luxury Property Boom

Itapema, a fast-growing beach city in southern Brazil, plans to artificially widen part of Meia Praia, its most valuable beachfront district, in an attempt to slow coastal erosion and protect urban infrastructure.

The project in Santa Catarina state, next to the high-rise resort city of Balneário Camboriú, received an installation environmental license from the Santa Catarina Environmental Institute (IMA) on May 6. Officials say the work will cover about 4.75 km (3 miles) of shoreline and cost roughly R$60 million, about USD 11 million at recent exchange rates.

What the Project Includes

The plan calls for dredging sand from a deposit about 19 km (12 miles) offshore and placing it along Meia Praia, between the jetties of the Perequê and Taboleiro das Oliveiras rivers. IMA said the sand has characteristics compatible with the native beach material.

The final width increase varies by source and by section. G1 reported that the beach would gain between 20 and 60 meters (66 to 197 feet) of sand, depending on the stretch. IMA described an average gain of 20 meters, while also stating that some sections could gain up to 60 meters.

The volume of sediment also differs slightly across the official material. G1 cited 416,000 cubic meters of sediment. IMA said the project may use between 416,000 and 498,000 cubic meters.

The schedule is not fully settled. G1 reported that work should begin in August and last four months. NSC Total reported an expected July start, after the end of the mullet fishing season, with completion before summer. The state environmental agency said the licensed works are expected to take four months.

Erosion and Urban Pressure

IMA and the Santa Catarina government describe the beach nourishment project as a coastal-protection measure against the advance of the sea and erosion processes that have historically affected the area.

Josevan Carmo da Cruz Junior, president of IMA, said the license was the result of technical analysis meant to assess impacts and define rules for the work. The agency says the project should increase the resilience of the beachfront against climate events and improve public use of the shore.

Meia Praia is among the most urbanized parts of Santa Catarina’s coast. Itapema had 75,940 residents in Brazil’s 2022 census, but its beachfront economy is shaped heavily by tourism, high-rise construction and second-home demand.

Real-Estate Stakes

The environmental project also sits at the center of a property-market story. According to G1, Itapema has the second-most expensive residential square meter in Brazil, behind only neighboring Balneário Camboriú, based on the FipeZAP index.

G1 cited an average of R$15,179 per square meter in Itapema, compared with R$15,185 in Balneário Camboriú. NSC Total, using April figures, reported R$15,073 for Itapema and R$15,146 for Balneário Camboriú. The discrepancy appears to reflect different reporting dates.

NSC Total reported that Itapema’s square-meter price rose 114% over five years and that real-estate professionals expect the beach widening to support a further gain of about 30%. That forecast is market opinion, not an official guarantee.

Mayor Alexandre Xepa said the project would protect the shoreline, expand use of the beach and raise Itapema’s profile. In comments quoted by IMA, he said he had “no doubt” that after the widening, Itapema would have the most valuable square meter in Brazil.

Developers are already positioning themselves around that bet. NSC Total reported that GT Home, a high-end builder associated with major projects in Balneário Camboriú, plans two seafront developments in Itapema, including one with more than 50 floors on the site of the former Shopping Andorinha.

For residents and visitors, the practical test will be simpler than the property ranking: whether the new sand holds, whether the work reduces erosion, and whether a denser urban waterfront can coexist with the coastal system it depends on.
