Mr. Schachter said that the new Gothamist will look very much like the old one.

“At the relaunch, Gothamist will operate as it was operating,” Mr. Schachter said. “If you were a Gothamist user, you went to Gothamist.com, you got a Gothamist newsletter, you followed Gothamist on social media — your Gothamist will be back. If you come to WNYC.org, we will find a way to represent Gothamist on our home page.”

He said that WNYC and Gothamist’s strengths would play well together.

“We have a big reporting staff covering local news that Gothamist has never had,” Mr. Schachter said. “Gothamist has a connection with the audience that we have on the radio, but have struggled to find in text and visuals. We think that the two organizations have a real complementary set of skills and assets to bring together.”

The news was first reported by Wired.

WNYC will also maintain the archives of DNAinfo.

Many details of the integration remain to be worked out. WNYC plans to bring aboard Gothamist’s founders — the publisher Jake Dobkin and the editor Jen Chung — and a number of other Gothamist editors, who will work with WNYC journalists to relaunch the site, Mr. Schachter said.

Union representation — the very issue that hastened the shutdown of Gothamist and DNAinfo — also remains a question mark.

WNYC employees who work primarily for digital platforms are not included in the station’s bargaining agreement with SAG-Aftra, which represents members of the on-air staff. Gothamist and DNAinfo journalists, whose work was purely digital, had just voted to join the Writers Guild of America East when they were shut down in the fall.
