I collected information about types of trees that last very long with little maintenance and provided a wide range of shading. It also shows watering system for the trees that is more efficient than the sprinkler. Water is important in the dry climate, it will be wise not to waste too much water. The population in the area are mostly middle age people and about 20% have family households. It is a good idea to add a playground for families and more seating space for office workers in the area.
