Mayor de Blasio will reportedly call for 90 homeless shelters to be built all around the city, as part of a plan expected to be announced Tuesday.

In addition to that measure, reported by The New York Times, a source told The Post that de Blasio intends to roll out an “equity plan” mandating neighborhoods house comparable numbers of homeless people.

The announcement will come as City Council members push several proposals seeking to bring relief to areas that are overburdened with homeless shelters, jails and foster homes.

Those neighborhoods — which include Brooklyn’s Brownsville, the South Bronx and Harlem — are home to a disproportionate number of facilities that house “residential beds,” according to a council report released on Monday.

The new measures, which are intended to revamp the city’s 1989 Fair Share initiative, would prohibit agencies from placing new facilities in already-saturated neighborhoods.
