Taoyuan Aerotropolis

Taoyuan Aerotropolis () is a large urban planning development at the Taiwan Taoyuan International Airport in Taoyuan City, Taiwan.
The 4,500 hectare development, centered around the existing airport, will include a districts for transportation, logistics, industry, and residential development, and has been called "one of Taiwan’s largest national infrastructure projects ever." The Aerotropolis is expected to create 200,000-300,000 new jobs, generate annual revenues of NT$2.3 trillion (US$75.4 billion), and accommodate 4.5 million tons of container cargo a year.
The development may require the acquisition of up to 3,200 hectares of land and the relocation of over 40,000 people 
A third runway and terminal will be added to Taiwan Taoyuan International Airport, boosting the capacity of the airport from 40 million to over 60 million passengers by 2025. Previously approved during the administration of Ma Ying-jeou, the Aerotropolis project proved to be controversial, "due to allegations of forced relocations, the prospect of added pollution, and insinuations of irregularities in land acquisition."
The Taoyuan City Mayor Cheng Wen-tsan, serving since 2014, has promised that the current, revamped version of the project will be developed according to five principles:
It will also strive to deliver low energy consumption, low pollution, and low water usage, along with high added value—guidelines that the mayor has dubbed "three lows and one high"—which will help resolve problems left from the Ma administration's approach to development.
