The city is taking steps to reduce the impact of heavy rainfall in the Homecrest neighborhood.
The project covers about 350 acres and includes Kings Highway, Coney Island Avenue and Avenues P through V.
The $95 million plan includes upgrading the tennis courts at Kelly Park, though the bulk of the work will be done underground.
Porous pavement will be installed in some parking lanes to help rainwater seep into the ground more quickly.
An underground storage tank beneath the tennis courts will temporarily hold excess stormwater until the sewer system can manage it.
Officials say the system will be able to handle 2.3 inches of rain per hour.
“This project will help protect homes, streets and businesses from extreme rainfall,” said Lisa Garcia, commissioner of the New York City Department of Environmental Protection.
Local officials say flooding has been a persistent problem in the area.
The project is part of a broader city effort to upgrade stormwater management in parks, schoolyards and other public spaces in South Brooklyn.
Officials say the network of projects is expected to handle about 30 million gallons of stormwater every year.
The plan is still in its design phase, with a community presentation set for mid-May.
Construction is expected to begin in three to four years.
