Once the site of a Wyeth factory that produced penicillin, a 30-acre brownfield in West Chester — vacant for around a decade — could soon become an e-commerce retail distribution center, writes Bill Rettew for the Daily Local News.

According to the developer’s plans, 611 East Nields Street would consist of a 143,000-square-foot, 42-foot-tall structure with around 1,000 parking spaces.

An undisclosed tenant is leasing the property by builder 611 E. Nield Street, LLC through E. Kahn Development. It will invest between $50 million and $60 million in the project.

The planning commission reviewed plans last week. Expectations are for borough council to approve the by-right-plan by August.

“It’s a dream-use with fairly low impact, and traffic is lower than Wyeth’s,” said Kahn. “It’s a great job creator for West Chester, with tax benefits.”

According to the builder, the new project will generate around $700,000 in annual real estate taxes. The new tenant expects to hire between 150 and 175 direct employees, along with 250 third-party contractors.

The factory that previously stood on the property was demolished by Wyeth about 10 years ago.
