This is our local park composting setup for leaves and grass, not long after having removed finished material. Leaves (browns) are abundant in late winter, and grass is abundant in summer. Water is usually an issue, as volunteers who take leaves don't have time to wet everything down, so that usually gets resolved when we turn the compost (a community event 2-3 times a year). We just had an automatic watering system installed, so that should help. Doors are attached with wingnuts and come off fairly easily.
