Most of the money the State Government has available for grants comes from the Federal level which they are distributing where there is need. For success, nonprofits need to show the level of impact their program will have on their local community. It is also very helpful to have the backing of bureaucrats and politicians to campaign for your cause.
There are not many places to look for State grant announcements. It's best to contact the department that is controlling the grant for further information.
