A: An impervious surface is a hard surface that does not let water soak into the ground or greatly reduces the amount of water that soaks into the ground. Examples include roofs, solid decks, patios, sidewalks, driveways, parking areas, and roads.Compacted gravel is considered an impervious surface.: Areas covered with grass or that are planted (such as forests or gardens) are not counted as impervious surface. For billing purposes, wooden decks (without roofs) and the area of swimming pools that actually hold water are considered pervious.
The Dalai Lama, along with scores of other Tibetan refugees, actually stays at McLeodganj, also called Upper Dharamsala, in the beautiful Indian state of Himachal Pradesh. McLeodganj is approx. 530 kms. from Delhi and approx. 100 kms. from Pathankot.
In exile, the Dalai Lama began the task of trying to preserve the culture of the Tibetan people and publicise their plight on the world stage. He appealed to the United Nations and persuaded the General Assembly to adopt resolutions in 1959, 1961 and 1965 calling for the protection of the Tibetan people.
