Combine Municipal Databases
I do some volunteer work with students in Trenton, NJ. One year one of the students I worked with had the misfortune of having his parents threatened with eviction. We were able to work it out, but that was as a private citizen. If a student's family is going to be evicted, that affects the students performance at school. Any family with children enrolled in a public school district, should be guaranteed help when threatened with eviction. Eviction notices are issued by the Sheriff. Once the Sheriff's office issues them, an electronic alert should go to the Board of Education about a given family. At that point there should be a posting to a site like donorschoose.org or some entity, asking folks if this family can be aided in come way by the private sector.
This would require a seamless municipal database, with a feed into multiple philanthropic sites.
