The city of Blumenau is managing various infrastructure developments. One project involves the construction of a new roundabout and water network in the Escola Agrícola neighborhood. This R$ 1,179,900.00 initiative, funded by a parliamentary amendment, aims to reduce traffic congestion and improve water supply for approximately 58,000 residents through the installation of a new water main.

Separately, larger-scale flood prevention works, including river desilting and the construction of an overflow channel, have faced a one-year delay. Despite a planned R$ 12 million investment in partnership with the state government, the municipality has not yet commenced work. Officials attribute the delay to necessary technical studies and project revisions required by the State Court of Accounts (TCE-SC) to ensure effectiveness. The project must still undergo bidding processes and environmental licensing before execution.
