Hanoi to build Hoa Lac super satellite urban area
The green belt area will include the agricultural zone on the west of Tich River, the ecological zone in Vien Nam Mountain, Ba Vi National Park and the green buffer zone near Hoa Lac Air Base.
The general planning of Hoa Lac Urban Area was also approved by the prime minister in 2015. The new urban area is 30km away from Hanoi's centre, next to Hoa Binh Province, Thach That District and Son Tay Town.
In 2011, the government approved Hanoi master plan to 2030 in which the city will have five satellite urban areas including Hoa Lac, Son Tay, Xuan Mai, Phu Xuyen and Soc Son. Hoa Lac will be the biggest out of five areas and play an important role in the capital's development strategy.
