Task Force member organization Citizens Committee for New York City offers grants of $500 to $3,000 to grassroots community groups in economically under-resourced neighborhoods to work on community improvement projects that bring neighbors together. Groups may be newly established or forming, and are not required to have 501c(3) non-profit status. Applications are accepted twice a year, in the fall and spring. The fall deadline is September 30.
