General obligation bonds are used by municipalities to raise money for a library a city hall. It is for non revenue producing projects. These bonds are backed by taxes from assessed value from property owners. So this is where im confused.. If Revenue bonds were issued then the money that is made from the project until the bonds mature would be used to pay the bond holders. You get this money from the use of the park. The city would get there ballpark the people that would never use the place will never have to pay for it and the people that use it will not mind that some of the proceeds go to paying back the bond holders.. this is not rocket science its business....
