DuPont has bought the former Bicknell Manufacturing properties adjacent to its waterfront plant.

The two properties had been eyed by Valerie Landsburg, who had proposed a major mixed-use development that would have included retail shops, offices and residences.

DuPont purchased the two properties — 8 and 11 Lime St. — Wednesday, May 1. The two lots include the former Bicknell building and an adjacent vacant lot. The two lots total about 2 acres that include the 26,000-square-foot former Bicknell facility.

"DuPont is often seeking opportunities to purchase adjacent property to its facilities. We are considering all options in regards to future plans for this new area next to our Rockland site, but nothing has been defined yet," DuPont spokeswoman Lindsay Torriero said Friday, May 3.

Sale prices have not yet been released, but the asking price had been about $1.8 million for the properties, which are assessed at about $700,000.

A telephone message and text message were left Friday with Landsburg about the sale of the properties she had been interested in developing with the help of investors.

DuPont had publicly expressed its concern to the Rockland City Council about a proposal to change the zoning on the Bicknell properties that would have allowed residences next to an industrial plant.

The City Council had given preliminary approval last month to the change to that waterfront zone to allow for residences on upper floors. A public hearing and final vote had been scheduled for May 13.

City councilors had mixed reactions to the proposed development, with Councilor Valli Geiger saying the city had waited for a long time to see development of the Tillson Avenue peninsula.

The former Bicknell properties were owned by two different limited liability companies, both owned by Miami real estate developer Finlay Matheseon, who had bought the properties in 2004.

Matheson also owns 2two acres on Tillson Avenue that had been the location of Redlon & Johnson.

DuPont is Rockland's largest property taxpayer and largest user of the sewer treatment plant. The DuPont plant, which it bought from FMC in November 2017, employed 107 people at that time. DuPont paid $440,000 in property taxes to Rockland last year.
