Your compost pile should have an equal amount of browns to greens. You should also alternate layers of organic materials of different-sized particles. The brown materials provide carbon for your compost, the green materials provide nitrogen, and the water provides moisture to help break down the organic matter.
Green Stormwater Infrastructure. Green stormwater infrastructure includes a range of soil-water-plant systems that intercept stormwater, infiltrate a portion of it into the ground, evaporate a portion of it into the air, and in some cases release a portion of it slowly back into the sewer system. Vision. Tools. Programs. Projects.
Among the Top Ten of the Infrastructure 100 is the Venice MOSE Flood Barrier project, which is one of the biggest public works projects in Italian history and will use compressed air to raise flood gates to protect Venice from flooding.
