Amazon was revealed Wednesday night to be the tenant of a $250 million new development on the site of the demolished Pontiac Silverdome.

Dubbed "Project Cougar" in Pontiac Planning Division documents related to the former home of the Detroit Lions, Atlanta-based Seefried Industrial Properties is proposing a 3.7 million-square-foot, two-building distribution campus for the Seattle-based e-commerce giant housing at least 1,500 full- and part-time workers.

The Planning Commission approved a permit for the 127-acre site Wednesday night to be used as a warehouse and distribution center. The project is expected to be complete by the third quarter of 2021.

In all, Seefried Industrial Properties envisions a roughly 3.5 million-square-foot, five-story fulfillment center, along with a one-story, 200,000-square-foot delivery station, the 30-page document says.

It also says that there would be 1,800 parking spaces for the larger building and 350 spaces for the smaller building, totaling 2,150.

Crain's reported last month on the developer, which has previously used similar cryptic nomenclature for Amazon.com Inc. developments. In Gaines Township near Grand Rapids, the project was initially dubbed "Project Rapids" before the Seattle-based behemoth was confirmed as the user of an 855,000-square-foot property there.

The fulfillment center employees' wages would start at $15 per hour, the document says. A final site plan review could come Oct. 2, according to the document.

The Seefried Industrial website says the company was founded in 1984 and has at least 23 million square feet of property owned and managed.

The company has developed distribution centers for Amazon totaling at least 7 million square feet in Birmingham, Ala.; Tucson, Ariz.; and Salt Lake City, according to its website.

It is also developed a large facility for the internet retail giant that opened earlier this year in Romulus.

In addition, it has developed properties for Mercedes-Benz USA and Best Buy, the company's website says.

The city and Triple Properties reached a court agreement in March 2017 to hire a demolition contractor and raze the 80,000-plus seat stadium, which was home to the Lions until 2002, when the team moved to Ford Field in downtown Detroit.

In February 2017, the city sued Triple Properties, which purchased the Silverdome at auction from the city in 2009 for $583,000, just 1.05 percent of the total 1975 construction cost of $55.7 million. The city alleged violations of building and safety codes, as well as illegal storage of vehicles.

Demolishing the property was the next major step to finding a new use for the property, which became run down and was photographed strewn with debris. It was generally considered an eyesore in the city of 60,000 people.

Demolition began in December 2017 with a partial implosion that initially failed. The second attempt at the implosion succeeded the following day.
