An idea: You could organize a toy exchange in the neighborhood, something like: “if you have toys you no longer want, bring them here, and take home anything you like”. Some toys will probably remain in the end. Leave the weather-resistant ones at the sand pit, offer donating the rest to the nearest kindergarten, throw the unwanted ones away. Do this regularly once or twice per year.
