Green areas are any place prepared with grass, flowers, trees, benches or other decorative or urban furniture elements, used as decoration or for public use. They do not necessarily have to have all the elements mentioned above, but must include one or some of them. They must occupy a minimum area of approximately 20 square meters (the average surface of the lounge of a 90 square meter home). Gardens, parks and playgrounds, treed plazas and small green areas (parterres, etc.), fields or meadows not destined for agricultural use will be cases to consider as green areas.
