When I did this we went to a local park. Like a play ground. We cleaned it, repainted park furniture, fixed the signs.. they were wood ones that we sanded down and varnished with outdoor sealer crap. Raked up leaves and tons of acorns. (This was in Texas) Of course we had some direction from the local parks office on paint colors and stuff that could be done. In fact they paid for and gave us the paint to use.
