NYC FloodNet expands sensor network to 500 by 2027 for real-time flood monitoring

Brooklyn is stepping up its flood management game with the introduction of a new network of flood sensors aimed at providing real-time data during storm events. At the recent Brooklyn Borough Board meeting, officials announced that the city has installed 72 sensors across the borough, part of a larger initiative to expand to 500 sensors by mid-2027. This network will allow residents to access a data dashboard that displays current flood conditions, including water levels at various locations.

During the meeting, it was highlighted that the sensors played a crucial role during the recent storm Ophelia, which hit the city hard on September 29, 2023. The sensors recorded significant flooding, with the deepest measurement reaching 36 inches in Gowanus. This data not only provides a quantitative measure of flooding but also helps inform emergency responses and infrastructure planning.

The initiative, known as FloodNet, emphasizes community engagement. Officials are working closely with local organizations to ensure that the data is accessible and useful for advocacy and understanding neighborhood conditions. Community flood reports, which consolidate sensor data, 311 reports, and local photographs, are being developed to help residents communicate their flooding issues effectively.

As the project evolves, city officials are seeking feedback from community members on how to improve the accessibility and utility of the data. The goal is to empower residents with the information they need to advocate for better flood management and infrastructure improvements in their neighborhoods. With ongoing efforts to translate materials into multiple languages, the initiative aims to reach a diverse audience and ensure that all Brooklyn residents can benefit from this critical information.
