A coalition of groups backing an expansion of supportive housing units for the homeless has launched an email campaign to push Gov. Andrew Cuomo, Assembly Speaker Carl Heastie and Senate Majority Leader John Flanagan to sign on to a memorandum of understanding that authorizes 6,000 units be built.

Funding for the construction was included in the passage of the 2016-17 state budget in April, but the money can’t be spent until the MOU is signed.

As such, the Campaign 4 NY NY Housing launched its email campaign this week to get the ball rolling on the issue.

So far, the effort has generated 2,850 messages from New Yorkers.

In the email, the state’s top leaders are urged to back the MOU now in order to stem the growing homelessness issues in the state.

“Every day that passes without this MOU is another day thousands of New Yorkers will remain homeless,” the email states. “We need action now.”

“The homelessness crisis affects 80,000 New Yorkers. Leaving them on the streets, in shelters and cycling in and out of institutional care is not only inhumane, it is extremely expensive for local and state governments.”

At the same time, the campaign has a web page set up for a “call to action” petition backing the MOU for supportive housing.
