Hi Stacey,
A playground project is a huge (and well worth it) effort that takes time and often a combination of fundraising, community support, and grants. Here are some resources that may help:
Hello, our elementary school in Atkinson NH is looking for funding to add a new playground at our school. Has anyone been successful with doing this or have any ideas? We tried Lowe's toolbox grant last year (didn't get it) and will try again for the next deadline but I'm hoping someone has other ideas. Playgrounds are extremely expensive so getting financial help is necessary. Thank you!!
