Once We Stood Grandly . . .

. . . now we slink out through the poor door:

Mayor de Blasio and other officials denouncing “poor door” entrances for subsidized tenants in luxury buildings actually voted in favor of a measure that made such separation possible, a Post review found.

When the lengthy text of a zoning resolution was amended by the City Council in July 2009, then-Councilman Bill de Blasio — who arrived late to the meeting — was among the majority who voted “aye.”

One provision said developers of market-rate condos could include affordable units on site, instead of off-site, while allowing for the separation of a number of services that included the entrances.

But de Blasio’s vote didn’t stop City Hall officials last week from putting the blame for the controversial Extell Development project at 40 Riverside Blvd. — which will have separate entrance for subsidized tenants — solely on former Mayor Mike Bloomberg’s team.

Among the other elected officials who voted in favor of the 2009 zoning changes are current Manhattan Borough President Gale Brewer and Public Advocate Letitia James.

The two were among those who took part in a press conference on the steps of City Hall this past Friday condemning the prior administration for signing off on the project.
