New investment will improve sports activities at Morley's oldest park.
The Lawn Tennis Association has shown its commitment to the courts at Dartmouth Park with the pledge of up to 40,000.
This will help to pay for the resurfacing of courts to a higher standard and the provision of improved fencing.
The work is estimated to cost between 35,000 and 45,000 and any extra funds will come from money paid by developers to the community.
"The courts are reasonably well used all year round," said Coun Judith Elliott, "but have not had any investment for several decades.
"The need for resurfacing has been apparent for several years and we have received requests for the work from a number of residents. We have worked with them to come up with a plan."
The four upper courts will be resurfaced and the lower courts will become the site of a multi-games area which will provide space for football and basketball.
Coun Terry Grayshon said the improvements would start in March, adding: "There has been some delay in progressing the refsurfacing of the tennis courts."
"But this has been due to the necessity of putting together a partnership bid."
The parkland was the first to be opened in the town on land was presented by the Earl of Dartmouth. The corporation laid out the park which was opened by the Earl in 1890.
Councillors have also agreed money for Hirst Park on South Queen Street which is to get new seating and planting.
They have also agreed with Gildersome Parish Council to upgrade Gildersome playground.
