Phoenix Considering Extensive Infrastructure Buildout for Taiwan Plant

Six months ago the big Taiwan Semiconductor Manufacturing Company announced plans to build a $12 billion manufacturing plant in Phoenix at an undisclosed site.

Now members of the Phoenix City Council are contemplating funding up to $205 million in new public infrastructure work to support the construction and operation of that plant.

According to a city document, the building of the infrastructure is important because the Taiwan Semiconductor Manufacturing Company will bring “one of the largest foreign investments in Arizona history and provide thousands of quality jobs” to the state.

If the council approves a development agreement with TSMC it will also be committing itself to more than $200 million in infrastructure work, including the construction of new streets, sidewalks, gutters, and streetlights.

The effort will also see the building of public water infrastructure with a pressure reducing station and 16-inch to 54-inch diameter water transmission lines, as well as wastewater system improvements with 15-inch to 60-inch diameter gravity sewer mains and one or more lift stations.
​
Although the exact location for the new plant has not been publicly announced, the Phoenix Business Journal last month said the facility will most likely go up on the north side of Phoenix, on a portion of 3,500-acre site near Loop 303 and Interstate 17.
