The money, from his Ward Member Grant fund, will replace grass safety matting with all-weather Fibrefall at the Hexham Avenue play area on Oak Spring Gardens in Bourne.
Cllr Reid is a board member for Elsea Park Community Trust, which runs the local community centre and also manages public open space and several play areas in the wider Elsea Park development.
He said: "With the community continuing to grow in this area and many families moving in, there is a real need for somewhere for the youngsters to go and unwind.
"It's great for them to get outside in a safe environment and I'm pleased to be able to help a cause which is close to my heart and to support Elsea Park's continuing growth."
The development sits south of Bourne town centre and benefits from the community centre, which has been at the heart of events and activities there since 2012, as well as a Co-op store which opened two years ago.
Elsea Park Community Trust manager Barry Cook said: "It's a busy area and the play equipment is bespoke, provided by Taylor Wimpey with our residents in mind.
"This money will enable us to replace the original matting with a much safer alternative to further protect any children who may fall while they're on the equipment.
"Our next major project is the delivery of an artificial grass pitch and pavilion to the north of Oak Spring Gardens. Working closely with Kier Living (who are providing a pavilion, parking, and access road) and with the majority of the funding for the pitch itself coming from the Football Foundation, it is hoped the facility will open early in 2020.
"A number of local football clubs have indicated they will enter into key partnership agreements with The Trust, and we have worked up a programme of use that will ensure the facility is financially sustainable and available to the whole community."
In addition to managing play and recreation spaces, the Trust's groundsman maintains the extensive conservation areas and the majority of the children's play parks - as well as ponds and watercourses on land owned by The Trust.
