From the Morning Memo:

A measure introduced late last night by Senate Majority Leader John Flanagan would extend mayoral control of New York City schools for one year.

The bill would also seek to expand access to the state’s charter schools as well by raising the statewide cap on the schools by 100, from 460 to 560 — a proposal first backed by Gov. Andrew Cuomo at the start of the year.

The bill just hours after New York City Mayor Bill de Blasio left Albany following a round of meetings with Flanagan, as well as Cuomo and Assembly Speaker Carl Heastie.

Speaking with reporters, de Blasio had warned against a 12-month extension of mayoral control, saying such a move would make it a “political football.”

But de Blasio also said he secured no commitments from top state lawmakers and the governor on a host of issues, including mayoral control and rent control regulations as well as the 421a tax abatement reforms he is seeking.

Still, the measure has always been seen as linked to an expansion of the charter school cap. Statewide, there are fewer than 460 charters and opponents of argued a lifting of the cap is unnecessary.

Assembly Democrats, meanwhile, approved a bill last week that would provide for an unchanged mayoral control extension for the next three years, an expiration date that de Blasio said he could live with even as he pushed for keeping the system in place permanently.

Senate Republicans have called for unspecified changes to mayoral control in the city, though at least one Republican from the city, Brooklyn’s Marty Golden, backed an extension.

The GOP conference are not political allies for de Blasio, who backed Senate Democrats politically in last year’s elections. Republicans gained full control of the chamber last year.

Incoming Senate Education Committee Chairman Carl Marcellino said in an interview last week that mayoral control as well as the charter cap expansion would ultimately be a “conference decision.”
