Anand Arya and Kannan Jaiswal, residents of Sector-15-A, Noida, said they had decided to file a PIL in the apex court in this connection.

The residents are concerned about construction on the Yamuna bank and the resultant damage to the environment.

The Noida Authority is constructing a boundary wall on the Yamuna bank situated in the green belt area. Residents allege that thousands of trees have been uprooted for this construction.

Residents allege that there are many parks opposite Sector-15-A, like Mansrover Park, Nature Trail, Children Park, Navyug Park, Sumriti Van and Nar Greh Park. Thousands of trees in these parks and in the entire green belt have been uprooted for the construction of this wall. A six-foot deep foundation has been dug up, which is eight-and-half-foot high from the ground level, say the residents.

They further complaint that the construction work is causing dust and noise pollution. About 50-60 metres from the construction site is the Okhla Bird Sanctuary where Siberian birds come in winter. The noise and pollution affects these birds.

According to the guidelines of the union ministry of environment, says Anand Arya, no heavy construction work is allowed within 10 kms of a bird sanctuary.
