These Mello-Roos districts are created to raise public financing through the sale of bonds, for the purpose of paying for public improvements and services for that community. The services may include water lines, sewer treatment, drainage, streets, schools, electricity, parks, etc. The Mello-Roos tax is used to pay for the bonds used to pay for these improvements. The passage in 1978 of Proposition 13 restricted local governments ability to pay for capital facilities and services by increasing property taxes. In 1982, Senator Henry Mello and Assemblyman Mike Roos enacted the Community Facilities District (now called Mello-Roos) to provide local governments with an additional way to raise needed funds.
